1、阅读下面短文,根据题目要求用英语回答问题。请在答题卡指定区域作答。
Japan started releasing nuclear-contaminated water into the Pacific Ocean on August 24th and will continue to do so for at least 30 years. In the face of strong questioning and opposition from the international community, Japan plays word games by referring to the discharged "nuclear-contaminated water" as "treated nuclear wastewater".
However, the two are fundamentally different. Nuclear wastewater refers to the wastewater produced during the normal, daily operation of a nuclear power plant, such as large quantities of water used to cool down the reactor of the plant. Because the water doesn't touch radioactive substances(放射性物质)in the nuclear reactor, it can be flushed out after strict processing.
Nuclear-contaminated water refers to cooling water that comes into direct contact with radioactive materials inside the reactor when the reactor is breached after a nuclear accident. The cooling water becomes contaminated with highly radioactive substances, thus becoming nuclear-contaminated water.
The Fukushima nuclear power plant experienced a major incident in 2011, bringing water into contact with radioactive substances. The Japanese side's conflation(混淆)of this with wastewater from normal operations is a deceptive attempt to hide the truth. The Japanese side claims that the multi-nuclide treatment system ALPS is used to treat nuclear contaminated water, and that the treated water is safe and even meets drinking water standards. However, such statements fail to alleviate public concerns. Japan has yet to address major international concerns, such as the long-term reliability of the purification facility, the authenticity and accuracy of the nuclear-contaminated water data, and the effectiveness if the monitoring arrangement. This is extremely selfish and irresponsible, as the discharge will spread the risks of nuclear contamination to the rest of the world.
(1)、How does the Japanese mislead the international community?(2)、In what way nuclear-contaminated water is different from nuclear wastewater.(3)、Please decide which part is false in the following statement, then underline it and explain why.> Japan's deceptive attempts to hide the truth alleviate public concerns over the long-term reliability of the purification facility, etc.
(4)、How is Japan's dumping nuclear-contaminated water related to you? (In about 40 words) -

Have you become really interested in self-improvement lately? This pursuit of more and better things, whether they be better health, clothes, or money has been normalized, but sometimes to the detriment of people's wellbeing. This self-improvement mindset can make you feel disempowered, like you should be someone else. Here are five time-wasting self-improvement habits that are harmful to you.
Extremely high and unrealistic expectations
Having goals can be very helpful since it can help give you something to work towards and place your energy into. This is a harmful habit because you're not focused on yourself and your enjoyment of life, but on achieving other people's ideals. Remember, you don't have to be perfect, you just need to be yourself.
The quick culture mentality
The idea about how you must never give up or that you must constantly hustle, even at the expense of your health can be very damaging to your wellbeing. Sometimes, things just don't work out and you need to give up, but that's not a bad thing. As much as there are people who have support themselves and others by working long hours, constantly hustling without taking any breaks for yourself to get your bearings may only lead to burnout.
Putting aesthetics(审美)over health
Social media can be a tool to help you change your life for the better, it can also mislead how you see yourself and others. Women are implored to get dangerous, unnecessary cosmetic surgery and men are told to be jacked and in the gym by any means for those gains, but our bodies are not trends that we should be ashamed of.
Information without application
Like many others, you may decide to apply the self-improvement information once you finished reading all of it, but there are so many books about it and new ones keeps coming out. As powerful as knowledge is, applied knowledge is the best kind. Don't be afraid to apply what you've learnt into the world.
Visualizations without action
Perhaps you see yourself as a painter, or you wish you'd have a big house. Visualizing the life you want and putting it out there can be a great way to get yourself motivated. However, this can become an issue when you only put it out there and dream about it with nothing in between to bridge the gap. Remember that you have to actually do it to get there.
A. It can be heartbreaking and tough, but it may be necessary.
B. It will be too bad if you fail to keep your momentum and work on.
C. You need to create great expectations in order to drive yourself forward.
D. If it lacks the structure and action, all you dreamt about is only a dream.
E. However, you might create wild expectations which are too much for yourself.
F. Instead of promoting healthy lifestyles, it advertises certain body types as desirable.
G. All of these how-to's can be helpful, but they are useless if you don't actually use them.

Making electricity out of fossil fuels releases lots of greenhouse gases, which accumulate in the atmosphere and heat up the planet. Nuclear power, on the other hand, has the potential to be an almost unlimited and more climate-friendly energy source. That is because in contrast to fossil fuels, no greenhouse gases are released directly during the immediate use of the fuel.
However, there are also several major problems. First, the mining of nuclear fuel is costly and energy intensive and causes many environmental problems. Second, nuclear energy production generates significant amounts of radioactive waste, which is extremely dangerous if not handled safely. Finally, the entire process requires very complex and energy intensive infrastructure(基建), which contributes to indirect greenhouse gas emissions.
We use computer and mathematical models to understand if it might be possible to redesign nuclear power stations in a way that they run on nuclear waste. This would reduce the negative impacts of current and future nuclear power generation immensely.
Our model show that it is feasible(可行的) to redesign nuclear power stations in a way they can run on spent nuclear fuel (SNF). Plus, the SNF does not have to be further modified before it is used. Even better, our advanced nuclear power stations do not produce any additional waste. While these innovative power stations do not yet exist, our research indicates that they are a real possibility for the future.
In our research, so-called molten salt reactors seem a promising candidate for the new type of nuclear power station as they could be redesigned to run on SNF. Molten salt reactors operate on fuel melt in liquid salt. Over a lifetime of 60 years, one of these reactors would "eat up" roughly 70 tons of SNF. This amount accumulates in 3 to 4 years of operation in a traditional nuclear power station of comparable size. Our suggested redesign would make nuclear energy generation much more efficient and sustainable, as it could "squeeze out" up to 20 times more energy from already spent nuclear fuel. It would also eliminate any SNF as a source of highly problematic waste.
Creating nuclear power stations that can run on existing nuclear waste is a worthy endeavor, and our feasibility analysis shows that it can likely be done. However, we need a lot of innovative and multidisciplinary research to put this vision into reality. "Eating up" radioactive waste as fuel would eliminate the long-term storage problem of current nuclear waste. Also, it would relieve us from the costs and environmental damages done by mining current nuclear fuel and the complicated processes required for long term operation. The new operational model would only consist of melting the SNF, operating the reactor, and cleaning the fuel salt. All in all, it would reduce many environmental, social and political issues of current nuclear power production. Using our current nuclear waste as fuel would allow us to take full advantage of the climate-friendly aspect of nuclear power generation.
Even in science and technology, it's important to realize when we have to rethink our current approaches and what our options are for improvement. Current nuclear power stations have been created with past technologies and goals in mind. Nowadays, some people claim, they might create often more problems than they solve. We need innovative alternatives to provide sustainable, safe and clean energy for generations to come.

Chinese scientists recently achieved precise total synthesis(合成)of sugar from carbon dioxide in the laboratory, marking a crucial step in artificial sugar synthesis.
The synthesis, which took more than two years to realize, was achieved by teams from the Chinese Academy of Sciences' Tianjin Institute of Industrial Biotechnology and the academy's Dalian Institute of Chemical Physics. Their research was published last week in a paper in Chinese Science Bulletin, a multidisciplinary academic journal.
Sugar is a major source of energy for the human body and a key raw material for industrial production, and it is mainly obtained by extracting it from crops such as sugar cane. However, the traditional method of extraction is limited by the energy conversion efficiency of plant photosynthesis. Moreover, the process of extracting sugar has been affected by uncertain raw material supplies due to land degradation and shortages, ecosystem degradation and extreme weather and natural disasters caused by global warming.
As a result, artificial sugar synthesis has been continually studied by the scientific community in recent years, and scientists around the world have contributed to the effort. In their latest research, the Chinese scientists adjusted high-concentration carbon dioxide and other raw materials in the reaction solution. With the help of chemical catalysts and enzyme(酶)catalysts, they obtained four kinds of sugars: glucose, allulose, tagatose and mannose.
The experiment lasted about 17 hours, much shorter than the time required for traditional methods of sugar extraction, according to Yang Jiangang, lead author of the paper and associate researcher at the Tianjin institute.
The efficiency of sugar synthesis in this study was 0.67 grams per liter per hour, which was more than 10 times higher than the previous results achieved by scientists worldwide. Yang said that the carbon dioxide to sugar conversion rate of glucose reached 59.8 nanomoles of carbon per milligram of catalyst per minute. This is the highest level of artificial sugar production known domestically and internationally.
The study also achieved precise control of artificial sugar synthesis. "By controlling the varied catalytic effects of different enzymes, theoretically almost any type of sugar can be synthesized," Yang said. Regarding the study, Manfred Reetz, a member of the German National Academy of Sciences Leopoldina, said it is a particularly challenging task to convert carbon dioxide into sugars.
The achievement by Chinese scientists has provided a flexible, multifunctional and efficient sugar synthesis route, which opens a door for green chemistry, Reetz said. Green chemistry, similar to sustainable chemistry, is a rapidly developing field that focuses on how to fully utilize raw materials and energy in the process of producing the intended product while minimizing or eliminating the use and generation of harmful substances.
Carbon dioxide to sugar conversion is seen as an example of green chemistry, since it was conducted under normal temperature and pressure conditions and did not yield any harmful substances.
(1)、Why do scientists keep studying artificial sugar synthesis?A、Because sugar is an essential energy source for industrial production. B、Because the traditional extraction approach is not environmentally friendly. C、Because raw material supply is unreliable in the process of traditional sugar extraction. D、Because the traditional extraction approach is less productive than plant photosynthesis.(2)、How is the Chinese study significant?A、It synthesized almost all types of sugar in the laboratory. B、It controlled varied catalytic effects of different enzymes. C、It converted high-concentration carbon dioxide into sugar. D、It lasted 17 hours, shorter than previous traditional methods.(3)、What can we infer from the passage?A、Green chemistry helped use up all raw materials to generate more products. B、Carbon dioxide to sugar conversion will be used in industrial production soon. C、Green chemistry is a new field where Chinese scientists will put more efforts on. D、Carbon dioxide to sugar conversion will take up all sugar production due to its efficiency. -

Anna, a young writer, often visited this oasis(绿洲)of knowledge. She was on the 3 of publishing her first book but was facing the crippling self-doubt that often troubles creators. One evening, as she wandered between the shelves, she happened to see an old, dusty 4 . It was a journal from the 1800s, written by a then-unknown writer named Lillian.
As Anna skimmed through the pages, she was 5 by Lillian's struggles which mirrored her own. Lillian wrote of her rejections, her moments of despair, and the nights she wanted to give up. But she also wrote of her 6 moments, where the words flowed like a river and the stories took a life of their own.
The final entry was dated a day before Lillian's first book was published. It read, "To the future dreamers who may find this: Remember, every 7 has its dawn. Your struggles are merely the dark before the morning light. Keep writing, keep dreaming, and one day, your stories will light up someone's 8 just as you have lit up mine."

18-year-old Sadiya was born in Deora, a small village in eastern India, but moved to the city of Mumbai when she was 3. In 2020, when the pandemic (疫情) broke out, her father's small business was forced to close temporarily and the family returned to her ancestral village to wait out the pandemic.
However, it greatly shocked her when she found that attending school was uncommon in Deora, where almost half of the villagers couldn't read. Unable to afford textbooks, many families often withdrew their children from schools. They didn't wish to educate their children, many of whom had to work in the fields with parents though some had the desire to read.
Sadiya, the college girl with a strong sense of social responsibility, has been trying to seize opportunities to open doors for others. Fluent in Hindi, Urdu, and English, she often speaks at inter-college events on the right to education and enjoys a high reputation among college students.
Used to taking on challenges, Sadiya was determined to do something for the children. One day last July, Sadiya sat down with her family elders and proposed the idea of setting up a library. Many shook their heads in disagreement this wasn't how a young girl should spend her time.
After many discussions, Sadiya finally convinced them and gained access to her relative's guesthouse, mending it with $67 that she'd won in public-speaking awards. She took the help of her uncle, Akbar, and cousin, Nawaz, and got to work. Walls were repainted the bamboo roof was repaired and lights and bookshelves were fixed, and the room was filled with chairs and a long table. Vivid charts stuck on the walls — from anatomy (解剖) to transportation, lightened the space.
Looking at the newly-decorated "library", Sadiya couldn't hold back her excitement while imagining the children reading books here by light.
All was ready except books. So what Sadiya was desperate to do next was fill the shelves with books. She drew on all her savings and purchased many books suitable for children online.

Volunteer travel involves taking a trip all or part of the purpose is to participate in an arranged service opportunity helping others. Usually, these trips are arranged by church organizations, human interest groups, non-profits.
Charitable interests often go far beyond national boundaries and sometimes, donating money is not enough (satisfy) the need to help. Volunteer travel is a way to combine a visit to a new location meaningful work that has a direct impact on communities in other parts of the world.
This type of travel has been option for many years. (historic), church groups made up a large part of this market. Once a year a religious organization would organize a trip to another country. The primary purpose of the trip was very specific. For example, it would be to help build a school, dig wells or engage in hundreds of other (project) that would impact those less fortunate.
As international travel becomes by far (easy), volunteering in other countries has become as accessible as browsing a website and signing up. Instead of (travel) with a group that is organized at the volunteers home base, the volunteer may join a group that gathers at the worksite from all over the world. This sort of volunteer travel (refer) to as voluntourism or vacanteerism from time to time.

The research by OECD that was analyzing the homework of 15-year-old school kids has shown that Italian children are overwhelmed with homework as they have to spend over 9 hours on it weekly. The other countries where children have to work over 6 hours on their tasks are Ireland, Poland, the USA and Australia. No wonder children would rather find hundreds of other activities than do their home assignments. According to the Cooper's review of homework studies, 70% of students show better academic success thanks to homework they were completing. Consequently, we should not underestimate its benefits and now it is time to focus on the reasons why it should not be banned.
Additional practice
Sometimes the percentage of this knowledge is relatively low, but the requirements of the curriculum make teachers give many self-study tasks home for them to achieve better test results. Moreover, the obligation to repeat the material learnt at the lesson contributes to its better memorizing and understanding.
It teaches students responsibility
When students only visit classes, they have no idea how difficult it is for teachers to prepare for the lessons and may behave abusively. These features can be very useful for the future career too.
It teaches important life skills
When we say that students do their homework, we implement many meanings in this phrase. Pupils learn to manage time effectively, set priorities, and improve self-discipline.
If teenagers would have too much time for leisure activities, the probability that they will interfere with some illegal or criminal issues rises greatly. Being busy with tasks, they do not waste their time and spend it with the unmatched benefit.
A. It keeps students busy.
B. It enriches students' knowledge.
C. Therefore, it's high time that homework should be banned.
D. Not all the information is grasped by students at the lessons.
E. That is a good preparation for future career and meeting deadlines set by bosses.
F. At the same time, each person realizes that homework is extremely important in studying.
G. When they are given assignments on a regular basis, they raise responsibility, punctuality, and execution.

A new study of older adults finds excessive daytime napping (小睡) may signal an increasing risk of Alzheimer's disease. Investigators from Brigham and Women's Hospital report a relationship between daytime napping and cognitive (认知的) aging: excessive daytime napping predicts an increased future risk of Alzheimer's, and a diagnosis of Alzheimer's speeds up the increase in daytime napping during aging.
"Daytime sleep behaviors of older adults are often ignored, and a consensus (共识) for daytime napping in clinical practice and health care is still lacking," said Peng Li of the Medical Biodynamics Program in Brigham's Division of Sleep and Circadian Disorders. "Our team calls for a closer attention to 24-hour sleep patterns — not only nighttime sleep but also daytime sleep — for tracking the health of older adults."
Researchers at the Brigham recognized that all previous studies on Alzheimer's disease assessed napping within a participant only once, most of which were subjective and questionnaire-based. In the new study, more than 1000 individuals, with an average age of 81, were provided Actical, a watch-like device, to wear on their wrist for up to 14 days. After napping episodes were identified, the nap duration and frequency were calculated.
The results suggest that excessive daytime napping may signal an increasing risk of Alzheimer's, and that faster yearly increase in daytime napping may be a sign of worsening or unflavored clinical progression of the disease.
Researchers acknowledge that although the method of the new study has been widely used in sleep field studies, they recognize that polysomnography (多导睡眠记录仪) is the gold standard for sleep scoring. Moreover, the participants studied were older, and therefore, the findings may not be easily translated to younger people. In addition, future studies should test whether a direct intervention in daytime napping can lower the risk of Alzheimer's or cognitive decline.
"We hope to draw more attention to daytime sleep patterns and the importance of patients noting if their sleep schedule changes over time," said co-senior author Kun Hu of the Medical Biodynamics Program. "Sleep changes are critical in shaping the internal changes in the brain."
(1)、What is the new study about?A、Ways to prevent Alzheimer's disease. B、Causes of sleep disorders in older adults. C、The symptoms of age-related cognitive decline. D、The link between Alzheimer's and daytime sleep.(2)、What does Peng Li's team advocate?A、Encouraging elders to get enough rest at night. B、Investigating the health of elders with poor sleep. C、Monitoring elders' sleep patterns throughout the day. D、Providing good health care for elders with Alzheimer's.(3)、What does the underlined word "episodes" mean in Paragraph 3?A、Periods. B、Incidents. C、Experiences. D、Series.(4)、What is Paragraph 5 mainly about?A、Advice on adjusting sleep patterns. B、Limitations of the present research. C、The potential value of the study findings. D、Supporting evidence for the research results. -

The world's biggest electric vehicle — a 45-ton mining dump truck named the eDumper — may have to give up its throne. A newcomer powered with both electricity and a reserve of hydrogen fuel, is going to steal that title as the largest electric mining truck.
London-based Anglo American is developing the beast of a machine — it weighs 290 tons — as part of its sustainable mining vision. The conceptual work is done, but UK-based Williams Advanced Engineering will bring the truck to life. The idea is to replace the vehicle's diesel engine (柴油机) with a high-power modular lithium-ion battery (锂电池). "We are delighted to be involved in this innovative and exciting project which shows the potential of battery technology that can adapt to increased demands, from automotive and motorsport to ‘heavy duty' industrial applications," Craig Wilson, managing director of Williams Advanced Engineering, said.
While the eDumper — a mining truck used to move stones from the sides of mountains in Switzerland — relies entirely on pure electricity and pure physics for power, the Anglo American truck will use both a lithium-ion battery and hydrogen fuel cell (电池) module. Altogether, the new truck will have over 1,000 Kilowatt hours of energy storage.
Hydrogen fuel is a clear fuel that produces only water as a by-product when consumed in a fuel cell. It's typically produced from natural gas, nuclear power, or renewable wind and solar power. Adding hydrogen fuel cells to the vehicle's battery will allow the truck to run for longer periods of time without recharging.
There's also a third type of power that comes into play with the Anglo American truck: kinetic (动力的) energy created through the process of regenerative braking (再生制动系统). When an electric vehicle — be it the Anglo American truck, or the eDumper — rolls down a hill, that movement creates electrical energy for the battery as you brake. The electric motors power the car through the battery's stored energy, but can also become mini generators that return some energy back to the battery.
After Anglo American finishes test trials with the truck, the firm will conduct studies to understand how the truck's power units can be used to provide energy storage in other applications.
(1)、What can be known about "the eDumper"?A、It weighs more than 290 tons. B、It is powered by hydrogen fuel. C、It will no longer be the largest electric truck. D、It will discourage buyers for being expensive.(2)、What is Craig Wilson's attitude towards the future of the lithium-ion battery?A、Negative. B、Neutral. C、Indifferent. D、Positive.(3)、What is the benefit of adopting hydrogen fuel cells?A、It can save a lot of money. B、Vehicles become more eco-friendly. C、It has no environmental impact at all. D、Vehicles no longer need to be recharged.(4)、According to Paragraph 5, which of the following can be a feature of regenerative braking?A、Autonomous braking. B、Energy transformation. C、Simple operation. D、Zero-carbon emission. -

Bookstores, like wines, have different notes, different flavors, each one distinct. There are the musty (有霉味的), odd ones with random piles and dusty rows, usually with both used and new books. There are small independent stores charming and cozy. Then there's the big-box with long, straight rows, bright and dustless, usually featuring a cafe and a kids section you can get lost in.
My adoration for bookstores is, without a doubt, partly nostalgic (怀旧的). I came of age in the late 1990s, when Amazon was mostly known as a river in South America, phones were not smart____and bookstores were dotted around cities.
When my husband and I were dating, our go-to date was to get coffee and walk around bookstores together. It was the best. We'd move slowly, wandering through the religion section, the memoirs, fiction, poetry, history. I'd pick up a title I'd heard about and sit in the aisle reading a chapter. I'd find one I'd never heard of and scan the back cover. We'd sip our coffee and read each other interesting paragraphs from books we found.
I fell for bookstores and for my husband at the same time. So when stores began closing down all over America, we were both sorrowful. What were we supposed to do with a night out now?
In a recent very informal and unscientific poll (调查) of my friends, I found that many of us love and miss physical bookstores. Friends described the feeling of discovery and exploration, the calming serenity (宁静) of being surrounded by words and ideas. My wise friend Greg said, "Bookstores are like the best parties: You may discover a new friend or join an unexpected conversation with a simple turn of your head."
I dream of an America with streets full of independent bookstores whose inventories (库存清单) contradict one another. But right now I'm in favor of any brick-and-mortar (实体的) book store, really. Any place that reminds us that the material world is beautiful and worth spending time in. Any place where we can learn how to exist together in communities full of words and ideas. Any place where we may discover something unpredictable and new. And if there's coffee nearby, even better.
