6、 读后续写阅读下面材料, 根据其内容和所给段落开头语续写两段, 使之构成一篇完整的短文。
Devi looked through the observation window at the kids below, all waiting in line to get into the pool. She turned to her mother with a furious frown on her face. "Mom, theyˈre all little kids! Iˈm 15 already! This is ridiculous!"
"I know, Devi, " replied her mother, "but youˈre a beginner, too, and you have to start somewhere!"
Devi had never been to a swimming lesson in her life. Between schoolwork and helping on her grandfatherˈs farm, she hadnˈt had time for lessons. The closest swimming pool Devi had been to was the alligator pool her mother bought her when she was five. Now that Devi was older, her mother had found a new job in the city, and Devi faced a new challenge-school field trips to the local pool.
The first day that Devi went with her class to the pool, she had no idea what she was in for. What could be so difficult about swimming? Devi confidently slipped into the water and held onto the side of the pool, expecting to be able to touch the bottom with her feet. But when Devi let go of the side of the pool, she slipped under the water-the whole pool was one big deep end! Devi threw her arm toward the side of the pool and grabbed the ledge (池壁), out of breath. "I really canˈt swim! Everyoneˈs going to laugh at me!" she thought to herself in a panic.
On the next field trip to the pool, Devi sat on the side on a bench, paralyzed with fear. She huddled with a towel over her shoulders, too embarrassed to try again. When she came home, her mother noticed right away that Devi was upset. "Honey, Iˈve signed you up for Angelaˈs swimming lessons at the local pool. Soon youˈll learn how to swim just like everyone else, " she assured Devi, showing photos of Angela with her prize-winning students.
注意:(1)所续写短文的词数应为150左右;(2)每段的开头语已为你写好;
Paragraph 1
Then came the time for Devi to take her first lesson.
Paragraph 2
Soon Angela came over to where Devi sat and introduced herself.

Iˈve always loved the ocean. In the (seven) grade, I started volunteering at the Monterey Bay Aquarium in California. I was upset to learn that many sea animals eat plastic garbage, (think)it is food.
I decided to do something (educate) people about this problem. I held presentations at schools to teach kids about plastic waste. I wanted to reach businesses too. I decided that if I learned of a company used a lot of plastic, Iˈd send it an email urging it to cut back.
One day, I saw a commercial for a health-care company. People in the ad were using plastic straws (吸管). I found the contact information of the company emailed its president. I told him how (harm) plastic could be to the environment and asked him to consider using more eco-friendly options. I was so (excite) when he wrote back to me. He said he would make sure that the company cut its use of plastic straws in half.
I kept going. Whenever I heard of businesses using plastic, Iˈd send an email. One of the biggest companies I wrote to (be) Alaska Airlines Paris. A company (represent) wrote back and told me the airline was switching overplastic to paper cups on all of its 1, 200 daily flights.

The summer after my freshman year college, I had to get my first job. This was probably one of the1 tasks I have ever had to do. I had never held a job when I was in high school because my parents wanted me to put all my 2 into my studies.
At first, it was very hard. I filled out dozens of 3 but got no calls back in the first two weeks. It made sense because I had 4 no job experience. All I could 5 was that being a high school graduate and a year of college.
However, halfway through the third week, I finally got a call back from one of the places I 6 . We had set up a meeting time, and after my 7 , I was more than ready to start working the following Monday. I was 8 at the chance of working for my wages.
When I started, it was very clear that I was not 9 . I made mistakes with orders and often 10 sales promotions(推销). My parents made a bet I would not 11 the first two weeks, and I would be back looking for more 12 . However, I stuck with it.
After working a while, I got better at orders, and always 13 the cheaper options for customers. A couple of weeks later, I had been told by the manager that I had 14 the award of the best employee of the month. It taught me a lot about responsibility and gave me the 15 of working.

10、 阅读下面短文, 从短文后的选项中选出能填入空白处的最佳选项;选项中有两项为多余选项。
In 1985, 16-year-old Douglas Casa, ran the championship 10, 000 meter track race at the Empire State Games. Suddenly, with just 200 meters to go, he collapsed on the final straightaway, with his body temperature at dangerous levels. He had suffered an exertional heat stroke(运动型中暑)or sunstroke.
From ancient soldiers on the battlefield to modern warriors on the gridiron(足球球场), exertional heat stroke, has long been a serious concern. And unlike classical heat stroke, which affects people such as babies and the elderly during heat waves, exertional heat stroke is caused by intense exercise in the heat.
So how do you diagnose an exertional heat stroke? The main criterion is a core body temperature greater than 40℃ along with signs of central nervous system disfunction such as confused behavior, or loss of consciousness.
As far as treatment goes, the most important thing to remember is cool first, transport second. The human body can withstand a core temperature above 40℃ for about 30 minutes before cell damage sets in. After any athletic or protective gear has been removed from the victim, place them in an ice water tub while stirring the water and monitoring vitals continuously. As you wait, itˈs important to keep the victim calm while cooling as much surface area as possible until emergency personnel arrive. If medical staff are available on site, cooling should continue until a core temperature of 38. 9℃ is reached.
As Dr. J Levick wrote of exertional heat stroke in 1859, "It strikes down its victim with his full armor on. Youth, health and strength oppose no obstacle to its power. " But donˈt be frightened so much for it has been 100% survivable with proper care.
A. Fortunately he survived with immediate treatment.
B. When possible seek out places with air-conditioners.
C. So itˈs necessary to start cooling as quickly as possible.
D. But emergency services should be called before you start.
E. The sun can also take lives away if people are not careful.
F. So far it has been one of the top three killers of athletes in training.
G. It is important to keep the body temperature close to its normal temperature.

Bruce, a parrot missing part of his beak (喙), creatively uses stones to clean feathers (羽毛), highlighting advanced intelligence in parrots.
Bruce lost the upper part of his beak in 2012 and was sent to live at a reserve in New Zealand. The defect made Bruce unable to search for food on his own, let alone keep his feathers clean with his beak. But in 2021, when comparative psychologist Bastos arrived at the reserve with colleagues to study parrots, zookeepers reported something strange:Bruce had seemingly figured out how to select and use small stones to clean his own feathers with his beak.
Over nine days, the team kept a close eye on Bruce, quickly taking, videos if he started cleaning his feathers. It turned out that Bruce had indeed invented his own way to do so, the researchers reported in Scientific Reports.
"It's crazy because the behavior was not from the wild, " Bastos says. When Bruce arrived at the reserve, he was too young to learn how to clean his feathers. And no other bird in the reserve uses stones in this way. "It seems like he just invented this tool use for himself, " she says.
Tool use is just one of parrots' many talents. They're famous for copying and even understanding human speech. Some species can also solve complex puzzles, like how to enter a covered rubbish bin or practice self-control.
For a concept as abstract (抽象的) as intelligence, it's challenging to develop a definition that applies across animals. Researchers often point to features once thought to make humans special—enhanced learning, memory, attention and movement control—as signs of advanced skills. However, many of these abilities can also be seen in parrots, as well as other animals like chimpanzees, dolphins and elephants.
"Parrots are our evolutionary (进化的) mirror image. These brilliant birds may teach us about how humanlike intelligence can appear, " behavioral ecologist Antone wrote in his 2022 book The Parrot in the Mirror. With powerful brains and a preference for words, these birds are "the very best example, " he writes, "of nature's 'other try' at humanlike intelligence. "
(1)、What does the underlined word " defect" in paragraph 2 mean?A、Disadvantage. B、Playfulness. C、Cruelty. D、Measure.(2)、Why did Bastos and her team watch Bruce closely?A、To observe how he lives alone. B、To find out how he gets food. C、To prove his ability to defend himself. D、To confirm his reported behavior.(3)、What can be known concerning the parrots?A、They do well in critical thinking. B、They're born skillful at using tools. C、They can complete complicated tasks. D、They can't match other animals in memory.(4)、What's the significance of studying the parrots?A、Offering an insight into human behavior. B、Helping further research other species of birds. C、Learning more about parrots' living environment. D、Giving reference for the evolution of humanlike intelligence. -

The hens look up at me from their nesting boxes. They seem slightly annoyed but unsurprised. A child runs up, pushes one of the chickens aside, and snatches two eggs. Around me, a half-dozen more children and adults collect eggs while a half-dozen others hand-feed dried mealworms to birds flocking around our ankles. I reach for an egg from an empty nest. There is something perfect about the way it fits warmly in the palm of my hand before I transfer it into a pretty wire basket provided to me by my hosts.
The egg harvest is a brief, carefully designed agritourism experience offering an experience of the labor rather than just having a bite of food. Snatching a few eggs and uprooting a few vegetables on the farm tour donˈt constitute a full dayˈs work, but it is also a useful reminder that food doesnˈt just magically appear on restaurant plates and grocery store shelves. Of course, visitors can take those eggs home or bring them to the on-farm restaurant, Clay, where a chef will use them to prepare breakfast.
A few centuries of industrialization, urbanization, and globalization have collected people into cities, but the attraction of the countryside has always remained. In the new urban-centered world, enterprising farmers have found plenty of opportunities to sell their rural lifestyle along with their crops. Italy promoted the modern model for combining agriculture and tourism in the wake of World War Ⅱ, when the national government encouraged rural populations to continue producing food rather than move to urban areas in search of more profitable jobs.
Agritourism acts as an umbrella term for a wide variety of activities that take place on farms, including farmstays, where guests sleep on-site. For varying investments of time, energy, and money, anyone can engage in our farming system, giving consumers a peek behind the farm-to-table world.
(1)、Why does the author describe children and adults collecting eggs in the beginning?A、To introduce agritourism. B、To describe the use of eggs. C、To show the innocence of the children. D、To emphasize the happiness of the children and adults.(2)、What is accessible to consumers in agritourism activities?A、Engaging in planting vegetables in person. B、Doing some simple but meaningful farm-work. C、Enjoying some self-made egg products on the farm. D、Clarifying the farm-to-table concept through practice.(3)、What can you learn from the last two paragraphs?A、The appeal of rural life gradually fade away due to industrialization. B、The desire to search for more well-paid jobs accelerated the speed of agritourism. C、Italian governmentˈs calls contributed a lot to the trend of moving from villages to cities. D、Promising farmers were dedicated to promoting their lifestyle along with agricultural products.(4)、What is the authorˈs attitude toward agritourism?A、Doubtful. B、Dismissive. C、Supportive. D、Sympathetic. -

Where does the meat on our table come from? It usually comes from livestock like chickens and cows. But did you know that meat can also be made in a lab? US company JUST has announced that lab-grown meat could be on some restaurant menus in the United States and Asia by the end of 2018, The Independent reported.
"These meats include chicken nuggets (鸡块), sausage and foie gras (鹅肝酱), " Josh Tetrick, CEO of JUST, told The Independent. Lab meat is sometimes referred to as "clean meat". It is made using the stem cells (干细胞) of living livestock. The cells need to be grown in a lab for a few weeks. For example, making a hamburger patty (肉饼) takes about nine weeks, CNN reported. This is faster than raising a cow, which usually takes over 20 weeks.
The first clean meat was a beef burger that was produced in 2013, but it was said to taste quite dry. How does clean meat taste now? Clean meat supporters told CNN that they think it tastes just like traditional meat.
Clean meat has other advantages. It is healthier than traditional meat. Meat producers can control what type of fat goes into the meat. They can produce clean meat that contains healthy fats, such as omega-3 fatty acids (脂肪酸). This kind of fat is good for people's hearts.
Clean meat can also help to solve global warming. According to The Washington Post, about 14. 5 percent of the planet's greenhouse gas emissions (排放) come from raising livestock. That's more than the emissions from every car, train, ship and airplane in the world combined. It is predicted that switching to clean meat could lower greenhouse gas emissions by 96 percent, The Independent reported.
(1)、Where may the meat we eat come from in future?A、Companies. B、Greenhouses. C、Labs. D、Restaurants.(2)、What can be used to make "clean meat"?A、Stem cells. B、Fatty acids. C、Hamburger patties. D、Chicken nuggets.(3)、What is the advantage of clean meat?A、It is fatty. B、It is healthy. C、It is free. D、It is smelly.(4)、What do we know about clean meat from the last paragraph?A、It comes from livestock. B、It can be switched off. C、It results in global warming. D、It benefits environment. -

20、 阅读下列短文,从每题所给的 A、B、C、D四个选项中选出最佳选项。
Natural selection is the process by which one type of animal within a species develops well because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth(桦尺蛾) is an example of the natural selection process.
In nineteenth-century England, certain types of peppered moths were able to better blend (融合) into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection usually takes hundreds or even thousands of years to occur. For the peppered moth, this process occurred relatively quickly .
At the beginning of the Industrial Age, most peppered moths in England were light-coloured and covered with black markings, although a few moths had dark-coloured wings. Because the light-coloured moths blended into the light-coloured bar k on the trees, they could not be easily seen by birds that would eat them. As the air grew more polluted, however, tree trunks (树干) became covered with soot (煤烟) and became darker. The light-coloured moths became easy for birds to see against the dark tree trunks. Since the dark-coloured moths now had the advantage, their numbers grew. Within 50 years, the peppered moth went from being mostly light-coloured to being mostly dark-coloured.
In the twentieth century, the air cleared up, and the peppered moth population changed again. As tree trunks lightened due to less soot in the air, light-coloured moths once again had an advantage. Their numbers increased as soot levels declined. Depending on their environment, the colouration of the moths helped them to be "naturally selected" to survive.
(1)、What was unusual about the peppered moth's natural selection process?A、Its uncertainty. B、Its complexity. C、Its contributing factors. D、Its length of time.(2)、What can we learn from paragraph 3?A、Both kinds of moths preferred dark-coloured trunks. B、Light-coloured moths were more sensitive to pollution. C、Different kinds of moths preferred different air conditions. D、Dark-coloured moths were originally easier to see on trees.(3)、What would most likely happen if soot darkened England's trees again?A、New species of moths would appear. B、Light-coloured moths would die out. C、Dark-coloured moths would rise in number again. D、Moths would be less dependent on their surroundings.(4)、What does the author want to illustrate with the example of moths?A、Nothing is permanent. B、It is the fittest that survives. C、Keep up with the times. D、Environmental protection is essential.
