Not all mosquitoes bite people. Male mosquitoes eat nectar from plants. But female mosquitoes need animal blood. When a female mosquito bites a person, it puts its saliva into the person's blood. This saliva might have a deadly disease in it. Sometimes the bite just makes you itch, but other times it can be very serious and even cause death.

Mosquitoes bite a lot of people in their lives. They can easily spread diseases from one person to another. Every year, over 700 million people get sick from these diseases, and at least 2 million people die from them.

Some people use mosquito nets over their beds to keep mosquitoes away. Mosquitoes also have natural enemies like bats, birds, dragonflies, and some fish. If we bring more of these animals to places where mosquitoes live, it might help reduce the number of mosquitoes. But this doesn't always work well. We can also use sprays or poisons to kill mosquitoes, but these can hurt other plants or animals too.

Even though mosquitoes don't look as scary as big animals, they're actually more dangerous to people. But things are changing. Scientists are working hard, and one day they might find a way to protect everyone from mosquitoes and the diseases they carry.

In a few studies, researchers found that young people are more motivated by scientists whose success comes from hard work than those who seem naturally brilliant, even if that scientist is Albert Einstein.

Danfei Hu, a student at Pennsylvania State University, and Janet N. Ann, a professor at William Paterson University, said their findings could help explain what it takes to succeed in science. Their research was recently published in a science journal.

Many students want to study science in school, but some give up on science careers after college. To help with this problem, Hu and Ann looked at role models, who can show students what goals to aim for and how to achieve them.

The researchers did two studies, one with 176 people and the other with 162 people. In the first study, everyone read the same story about a scientist's struggles. Half were told it was about Einstein, and the other half were told it was about Thomas Edison. Even though the stories were the same, people thought Einstein's success was because he was a genius. But those who thought the story was about Edison were more motivated to solve math problems.

Hu said, "People usually see Einstein as a genius, and they think his success is because he was super talented." But Edison is known for trying over 1,000 times to make the light bulb, and his success is linked to hard work. Hu added, "If students know that hard work can lead to great things, they'll be more confident in pursuing science careers."

Even with such a powerful imagination, Liu, who is 55 years old, probably didn't expect that he would become the first Asian to win the Hugo Award in 2015. That's the top prize in science fiction. He might also have never imagined that former US President Barack Obama would read his book The Three-Body Problem, or that he would win the 2018 Arthur C. Clarke Award for Imagination in Service to Society on November 9 in Washington DC. This was the first time a Chinese writer had ever won this award.

In his speech when he accepted the award, Liu said that his imagination came from Arthur C. Clarke, a famous UK sci-fi writer. He said that reading Clarke's book 2001: A Space Odyssey in the early 1980s changed his life.

"My mind opened up in a way it never had before. I felt like a small river finally seeing the ocean," Liu said. "That night, the night sky looked completely different to me. For the first time, I was amazed by how mysterious the universe is."

But even though Liu's imagination takes him to faraway places, his books always make sense. In The Three-Body Problem, for example, he tells a story about aliens coming to Earth. But instead of just focusing on the aliens, he talks about how different civilizations interact, the rules of survival, and what life means. In another book, The Wandering Earth, he thinks about what will happen when our solar system ends and humans need to find a new home. But all his ideas are based on real science. Liu's books aren't just dreams — they're grounded in facts.

History

Madrid has more than 3 million people. It has a really big palace, the biggest in Western Europe. Many people think it's the most beautiful building in Madrid. The palace has 2,800 rooms, and they're all fancy with nice furniture and art. Tourists can visit 50 of these big, pretty rooms.

Shopping

Madrid has some of the best shopping malls in Europe. People like to look for good deals in the stores. There's also a huge outdoor flea market called the Rastro. It's been around for 500 years. You can find all kinds of things there, like old stuff and CDs.

Entertainment

When you go to Madrid, you should see a flamenco show. Flamenco is a famous Spanish art. Performers sing, dance, and play guitars in small cafes and big theaters every day.

Food

Madrid has lots of different restaurants, but Spanish people usually eat dinner late, around 9 or 10 p.m.. So, it's hard to find good dinner food earlier. If you get hungry before that, you can go to a tapas bar. They serve small snacks. Make sure you try jamon, which is a special kind of ham. Spain is famous for it.

We sometimes take our loved ones' concern for granted and show our worst mood to the family. During my growth, an experience in senior high school stood out in my memory.

As a taxi driver, my dad drove through chaotic streets with heavy traffic. Sometimes he had to deal with rude passengers and struggle with thin income. Despite these, he never complained. Dad was devoted to our family and cared much about us. The sunflower keychain I had given him as a Father's Day gift in fifth grade had long lost its shine. Yet he had it attached to his leather belt everywhere he went. Every day, he simply headed out early in his worn-out uniform with two patches (补丁) and returned late with a tired but warm smile. When we joked about his "fashionable patches", he'd laugh and say, "These are my medals of honor!"

As I entered senior high school, my world became overwhelming. Math problems danced in my head. My grades didn't improve but even declined. School pressures skyrocketed. Even small things would set me off. Dad's daily "How's school today?" felt like another weight on my back. I was mean to his inquiries, even though I knew he meant well.

One day after a frustrating exam, I returned home, my backpack strap (肩带) cutting into my shoulder. Dad was calculating the taxi bills then. "Hey," he said, with a smile on his face, "How is …"

"STOP IT!" The words exploded out of me. "You're always in my business! Can't you just...leave me ALONE?"

He froze. The pen he was holding rolled off the table. His face fell, as if I'd thrown cold water on him. Then he stood up slowly and walked to his room. The door shut softly—not a slam (砰地关上), just a quiet click—that somehow hurt me worse.

Walking through his neighborhood supermarket in Australia, packs of Chinese sauerkraut (酸菜) line the shelves, Huang Xiqing feels like he's shopping in his hometown of Shenyang in Liaoning province. "The sauerkraut soup tastes just like home," says the 45-year-old Chinese living in Canberra, (sound) a little homesick.

Chinese sauerkraut, a pickle which (make) of Chinese cabbage, is a traditional specialty of the northeastern region and is now sold around the country exported overseas. Chinese cabbage has gained (popular) with ordinary household, because it is cheap and can be stored for a relatively long period of time.

During the last decades, Chinese businessmen have set several sauerkraut companies. Among them, the Xinmin agricultural product company of the Heilongjiang Cuihua Group has sold its Chinese sauerkraut not only (domestic), but also to countries including Canada, Japan and the United States. When people were making purchases for Spring Festival, sales of Chinese sauerkraut on Douyin increased more than10-fold, (compare) to the previous year.

But for Huang, Chinese sauerkraut is an everlasting link to home. "Although I have tried delicacies from across globe, Chinese sauerkraut is still one of my (favourite), and reminds me of my hometown," Huang says.

One morning, cyclists2 by — dark shorts, bright shirts, laughter floating like bells. Hesitant but3, I let my finger follow the headline on newspaper: "New Riders Welcome." It is not like me to join something where I know no one, but I4 myself to attend an organizational meeting.

At the first meetup, I5 my shyness and started a conversation with two cyclists. Days later, twelve newcomers began our first eight-mile ride. We6 through quiet neighborhood paths like a wobbling centipede (摇晃的蜈蚣). Soon, we were pedaling three times a week,7 increasing our distance and speed. Stopping to8 became our routine and we soon adopted our slogan, "We bike for food." As we sat chatting over cups of9 coffee, strong friendship began to form. As time wore on, many other shared interests emerged and we began10 them together.

Now,11 with several members of the cycling club, I decided to attend a handful of their social events. There, I met more folks. Out of these gatherings grew a small dinner group and again my circle12. More opportunities for gathering13 when our club members planned a few overnight cyclings.

Adventuring beyond comfort taught me more than cycling — it was courage as the oil that keeps life's wheels rolling toward14 and joy. Belonging begins where15 ends.

TV shows, movies, and music are consumed worldwide. But is this leading to cultural homogenization (均匀化) ? Are we all starting to dress, talk, and act the same way? It's a worrying thought. But on the other hand, media can also provide a platform for diverse voices.

Language is another hot topic when it comes to globalization. English has become the lingua franca (通用语) of the world. But what does this mean for other languages? Some linguists estimate that half of the world's more than 6000 languages will have disappeared by the end of this century. That is what really needs our attention.

Education is also hugely impacted by globalization. Students are no longer limited to their local schools or universities. This leads to a more global perspective, but it also means that educational standards are becoming more uniform. Is this a good thing or a bad thing?

So, what's the conclusion on globalization and its impact on culture? Well, it's complicated. There are definitely benefits—increased diversity, greater understanding, and more opportunities for cultural exchange. But there are also disadvantages—cultural homogenization, loss of traditional practices, and the threat of a global monoculture. Globalization isn't a one-way street. It's a process of giving and taking, of integrating and borrowing. And it's up to us to shape it in a way that preserves the best of our cultures and also accepts the new.

A. The key is to accept the complexity.

B. They are influenced by globalization.

C. They can study anywhere in the world.

D. Small, local cultures might feel threatened.

E. Media plays a huge role in cultural globalization.

F. It's the language of business, science, and the internet.

G. However, the spread of English can also contribute to global issues.

His research shows users of car-sharing platforms reduce their impact by only 3 to 18 percent — much less than 51 or 37 percent claimed in previous research. This is caused by so-called "rebound effects", which are rarely accounted for by companies or even researchers.

For example, shared vehicles are replaced with new models more frequently than private cars. Additionally, the introduction of sharing schemes (方案) can encourage people to drive when they would have otherwise taken public transport. These rebound effects turn out to be highly influential. Amatuni also found users of sharing platforms don't significantly reduce their driving. "And if they do, they often take buses and trains, which aren't emission-free," he says. While public transport is usually a better option, its impact is not negligible. So, this data must be included to make an accurate assessment.

Similarly, Amatuni discovered that a second-hand phone only offsets (抵消) about one-third of a new phone's production. Rebound effects are the cause. If people couldn't sell their old devices, they would use them for longer.

In other words, reuse both extends the lifetime of a device — by giving it a new owner — but also shortens it, as people tend to sell their newly bought devices sooner.

Amatuni doesn't want people to conclude taking small steps towards sustainability is pointless. "Our intentions are still what's most important," he says, "but meanwhile, people need to realise there're no easy fixes." He recommends prioritising overall consumption reduction rather than continuing current habits while trying to make them more efficient.

Today was my first day back in San Francisco after (camp) in the Redwood Forest and visiting the wine country of Napa Valley. I have to admit that it (definite) feels good to be back in the city again. And what a city — a city that was able to rebuild (it) after the earthquake that occurred in 1906.

My hotel is near downtown, in the Mission District, one of oldest parts of the city. Many of the people living here are from Mexico or Central America. This district used to be a poor area of town,it is now a centre for art, music, and food. In fact, an art (move) called the "Mission School" started here. It's influenced by graffiti art and comic art.

In the afternoon, I headed to a local museum showed the historical changes in California.I learnt that America got California from Mexico in 1848. In the same year, gold (discover) near San Francisco, which started a gold rush. Over 300,000 people came from all over the world (seek) their fortune, and San Francisco quickly became a big city. The museum did a really good job of showing how America was built by immigrants from different (country) and cultures. When these immigrants left their countries, actually they carried a bit of home in their hearts, and built a new home here.

At the park, Freddy and his classmates saw many different kinds of4. They were very beautiful. Then they went to5 a bird show. The birds performed(表演)so6. Freddy loved the show a lot.

Many people often lack energy and feel tired. If you are one of them, take the following suggestions to become an energetic person and make use of your full potential.

Manage your stress. If you are upset by emotions that result from stress, you will likely find that you have run out of energy. To control your stress, consider talking things out with a close friend or perhaps consulting a psychiatrist.

Take a nap when it is possible. Although you might be busy every day, there is always some time to get a few minutes of shut-eye. Don't sleep too long, or you might experience difficulty in falling asleep normally that night, which will throw off your whole sleep schedule.

Foods that have too much sugar can lead to glucose fluctuations (血糖波动) which then cause energy levels to decrease. Many people suffer from low energy due to a lack of protein. For fast and effective energy change, you can eat a few handfuls of nuts.

Schedule your time in a practical, realistic manner. Being too busy can decrease your productivity and do harm to your mental health. So try to get one day of relaxation a week.

Exercise out. Exercising out ensures sound sleep at night, and it helps oxygen to circulate, providing the cells with higher amounts of energy to burn. It also leaves you feeling refreshed and full of energy.

A. Eat less.

B. Sing alone or get up and dance.

C. Consider what you eat and drink.

D. Naps should be a maximum of 30 minutes.

E. In other words, emotions caused by stress eat up your energy.

F. This allows your body to get enough rest and gain energy for next week.

G. One highly effective way to become energetic is doing exercise regularly.

Cambodian people first came to the 38th District when they escaped from being killed by the Khmer Rouge during the 1970s. Cambodian traditions are kept alive in the celebration of the Cambodian New Year in April, which features (以……为特色) native food, religious events, and traditional Cambodian dances, with their costumes and beautiful movements. The Hmong people, who came to the 38th District because of the war in Vietnam, celebrate their New Year in December. Wearing colorful costumes, singing native songs and playing native instruments, the Hmong celebrate New Year by performing ceremonies to honor the dead and the spirits of nature.The tradition of the Indo­Americans in the District is kept through their social, professional and political clubs, and by wearing their traditional dress and performing folk dances from India. The Chamorro people, first from the Mariana Islands and Guam in the Pacific, hold an annual cultural fair in Long Beach; central to the Chamorran tradition is respect for elders, religious beliefs, storytelling, dancing, canoemaking, and the production of tools. Marking the end of slavery, Juneteenth was first celebrated on June 19 in Galveston, Texas, in 1865. Today African­Americans in Long Beach celebrate the holiday with choir performances, African dances and displays of African art products.

Individual events also help to combine many races and nationalities in the 38th District. Kidsday recognizes the outstanding achievements of 100 to 200 Downey youth in academic, athletic and community­based activities. Other 38th District events include the annual Downey Youth Fishing Day and the Anaheim International Festival street fair. The Long Beach Municipal Band is also important to the 38th District and so is Long Beach's sister city of Sochi, Russia.

Gradually, her health broke down, and she began to think that she could never work any more, but after a long rest in England, she came back to America and did something far greater than teaching. She went through the whole country where she first observed the inhumane treatment of the mentally ill. During Dorothea's traveling for nearly two years throughout the state, and meeting similar conditions, she always spoke kindly to the ill-treated, but she spoke wrathfully to the men who ill-treated them. In January 1843, she submitted to the Massachusetts legislature (立法机关) a detailed report of her fully documented findings.

In the next 40 years Dorothea inspired legislators in 15 US states and in Canada to establish state hospitals for the mentally ill. Her continuous efforts directly affected the building of 32 institutions in the United States. When the Civil War broke out, she went straight to Washington and offered to nurse the soldiers without pay. She hired houses to keep supplies in and bought an ambulance. She gave her time, strength and money to her country.

Dorothea Dix has been called the most useful woman of America. She is an, American educator, social reformer and humanitarian whose devotion to the welfare of the mentally ill led to widespread reforms in the United States and abroad.

Not much is known about Gellar's character on the show, except for the fact that she is playing Kristin Ramsey, an expert who moves to Los Angeles to find the person who started the wildfires. She spoke to Fox News Digital about her big return to TV, and explained why she thought she was drawn to projects featuring monsters (怪物).

"For me, it's always about the stories, and in talking today, we have discovered that the superhuman allows you to tell the most human stories because it really allows you to use these monsters to explore emotions, fears and anxieties that you can't experience in other worlds," Gellar explained.

"I think it's a really important conversation that people will be along for the ride, but then realize what the meaning is behind all of it," she added. Gellar's co-star, Rodrigo, agreed with her, saying he hoped audiences could look at the deeper meanings behind the monsters on the show and realize they were all metaphors (隐喻) to discuss in our own inner monsters."

Gellar recently told SFX Magazine she was very proud of the show.

As a crane (吊车)1 working on a construction site, Edwards2 found himself in a life-saving mission when a fire broke out. He recalled how he3 the trapped worker from his crane's cabin (驾驶舱), and how he came up with the idea of saving the man by lowerin a cage to him to let him4.

However, his attempt to5 the cage before the man was by no means an easy job, as each post (弹) of wind prevented to throw his crane off balance. Besides, the smoke and flames also added to the difficulty.6 the great challenges, Edwards refused to give up and fought to7 control. Luckily, someone on the ground offered8 on where to land the cage through a radio. Edwards9 the crane's movements, inch by inch, until the cage hanged (盘旋) just inches from the edge of the10. With determination, Edwards successfully landed the cage.

Eventually, Edwards watched the cage11 the man away from the horrible fire below and lowering him to safety. The crowd12 a big round of applause, a tribute (致敬) to the courage and skill13 by Edwards. He knew that his quick thinking and strong14 had made all the difference between life and death in the face of disaster.

A GoFundMe page has now been set up to raise money for him —— with organizers15 people to "buy Glen a beer" for his life-saving efforts.
