The dried baby worms will then be made into feed.These mealworms can be a continuous solution to several problems. Using a small land and giving out less carbon, they turn food waste into feed and offer an alternative source of protein. Ynsect SAS, a small French business that keeps mealworms to feed fish and pets, attracted money from investors includingIron Manmovieactor Robert Downey Jr. in a round of fund-raising last year.The deal will give Singapore's farmers access to domestically produced animal feed, which is traditionally bought from abroad. The Southeast Asian nation imports more than 90 percent of its food and has set a goal to produce a third of its food locally by 2030. It also aims to achieve a general recycling rate of 70 per cent by then. Presently, less than 20 per cent of Singapore's food waste is recycled.As part of the partnership, Dubai-based Dnata will add Blue Aqua to its list of suppliers to buy locally farmed seafood for its catering service.8. What is the function of mealworms?A. To cut the use of imported fish feed.B. To eat food waste and make fish feed.C. To domestically produce animal feed.D. To replace traditional fish and soybean meal.9. What does Paragraph 4 mainly talk about?A. The producers of the feed.B. The purpose of the projectC. The advantages of the project.D. The composition of the feed.10. What can we infer about Singapore from Paragraph 5?A. It is a rich country.B. It is short of self-produced food.C. Its recycling rate is very high now.D. Its farmers don't support the deal.11. What is the text mainly about?A. A new way to produce fish feed.B.An introduction to a company.C. A plan to reduce food waste.D. A deal to protect farmers.DAs a rider, Anna Kiesenhofe’s Olympics victory might be a surprise. The winner of the road race at the Tokyo Olympics left the sport at the end of 2017 when she found herself out of contract (合同). She came into Tokyo without a professional team and left as an Olympic champion.The 30-year old began her cycling career in 2014 after running injuries that prevented her from continuing her pursuits of triathlon (铁人三项). She later joined a Catalan team and won the Spanish National Cup in 2016.The then-26 year old signedher first professional contract with Lotto Soudal Ladies for the following season. However, she ended her 2017 campaign in April and did not sign a contract for 2018, eventually taking a year off the bike. In 2019, Kiesenhofer came back to the sport as a rider, winning the Austrian national road race. Despite her results, Kiesenhofer sill had no professional contract while going into the Tokyo Olympics.Kiesenhofer was the first rider to attack in the Olympic road race, eventually forming a breakaway along withCarl Oberholzer, Omer Shapira, Vera Looser and Anna Plichta, which went on to reach a gap of 11 minutes. After Looser and Oberholzer were dropped, Kiesnhofer ataced her two remaining breakaway companions.After Shapira and Plichta were caught by the peloton (主车群), the rest of the riders seemed to believe that they were racing among themselves for Gold, not knowing that Remehofere was still in front. While it might be a misjudgment from the rest of the peloton that allowed Kiesenhofer to keep her lead of more than two minutes, other riders’ mistakes should not detract from the Austrian’s efforts.Off the bike the new Olympic Champion has a PhD in mathematics after studying at the Technical University of Vienne as well as at Cambridge University. She currently works at the University of Lausanne.12. Why did Anna give up triathlon?A. She got injured.B. She lost interest in it.C. She had to attend university.D. She never won a medal.13.

Long-standing． D. World-class．BHave you ever noticed that some people can eat what they want and stay in shape, while others carefully watch what they eat and still put on weight? How annoying! However, scientists are beginning to believe that some people get the ability to stay thin from their parents.Scientists say that when some people eat, their bodies will naturally store the excess energy from food as fat. These people gain weight if they eat more than they need each day. Meanwhile, other people eat more than they need but their bodies are able to “burn off” the extra food without making fat, so they rarely have weight problems.To show that this is true, scientists have experimented on laboratory mice. They gave the mice a special diet with a lot of fat. Some mice gained weight while the other mice stayed thin, even though both groups of mice ate the same amount of food and got the same amount of exercise. Scientists concluded that weight gain seemed to be influenced by genetic (基因的) factors. They also believe they have now identified the genes that may cause this tendency. These genes, according to the scientists, get passed down the generations. Armed with this knowledge, they believe it may be possible to develop medicines thatcan target the genes and stop people from gaining weight.The study of weight gain is becoming more important as the numbers of people who are overweight continues to grow. In theUnited States, over seventy percent of the population have weight problems. This means they are at risk of illness such as high blood pressure and heart disease.Current medicines for weight control do not work very well because they can have serious side effects, such as heart problems. However, it takes a long time to develop and thoroughly test new drugs. Therefore, despite this breakthrough in the study of weight-loss drugs, scientists and health professionals all agree that currently the best way to control weight gain is to have a healthy, balanced diet and an active lifestyle with daily exercise. This will not only help people avoid becoming overweight, but also help them stay healthy and energetic.4. According to the scientists, some people ________.A. are able to stay thin because of genetic factorsB. can eat what they want and stay healthy foreverC. usually keep doing exercise to lose their weightD. don’t eat anything every day but still put on weight5. Some people don’t need to worry about weight problems because ________.A. they eat many vegetablesB. they eat less than othersC. they don’t store any energy from food as fatD. they can burn off the extra food without making fat6. What can we learn from the passage?A. Fewer people will have weight problems in the future.B. People with weight problems may suffer from heart trouble.C. We now have good medicine for people with weight problems.D. The result of the experiments on mice and humans are different.7. What does the last paragraph imply?A. Current medicine solve weight problems well.B. We should exercise regularly and eat properly.C. Taking exercise every day may cause heart problems.D. Testing new drugs is hard because of the side effects.CChimps use loud calls and gestures to make their feelings known but until now, the exact meaning for individual movements has remained a mystery. Now researchers believe they have translated the key gestures used in the chimp community and identified their intentions for the first time.From 4,351 gestures, experts were able to identify 66 that are used for 19 specific message meanings, including showing a foot to tell a child they can climb on their back. The researchers were able to narrow down these 66 gestures to 36 that are used intentionally to achieve 15 purposes. The translations were made by Dr Catherine Hobaiter and her colleagues at St Andrews University in Scotland.Dr Hobaiter used behavior sampling and filmed all recorded cases of gestural communication. Other gestures include stomping their feet to ask another chimp to stop what they are doing, and slapping objects together to ask another to follow them. Of the 19 meanings,17 encouraged interactions to start, or to develop, such as “move closer,” and “change play”. Some of the gestures were found to have more than one meaning. and only 10 of the 66 gestures were used for only a single meaning.Researchers collected a total of 471 video clips from two social groups of chimps at a shelter near Kinshasa, Democratic Republic of Congo. As well as identifying what the gesture means, they also discovered the technique needed to increase the chances of success.“Human children use gestures to communicate before they produce their first words, and their earliest gestures typically appear around 10 months of age,” explained the researchers. “In great apes, there is good evidence that language-trained individuals are capable of acquiring and understanding signals, but this is far less clear in their natural communication. ”8. Chimps slap the objects to____________.A. tell others to stop what they are doingB. ask others chimps to join themC. gather other chimps to move closerD. encourage interactions to start9. What did researchers find after studying 471 video clips?A. Chimps trained in language are good at understanding signals.B. Two social groups of chimps live at a shelter near Kinshasa.C. Language-trained individuals do well in natural communication.D. Chimps’earliest gestures appear around 10 months of age.10. How is the last paragraph developed?A. By analyzing causes.B. By examining differences.C By making comparisons. D. By following time order.11. What can be a suitable title for the text?A A New Research on Chimps B. Human Children and ChimpsC. Getting the Chimps Trained for LanguageD. Translating the Sign Language of ChimpsDThe shade of a single tree can provide welcome relief from the hot summer sun. But when that single tree is part of a small forest, it creates a considerable cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our cities cool.According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. And the effect is quite noticeable from neighborhood to neighborhood, even down to the scale of a single city block. “We knew that cities are warmer than the surrounding countryside, but we found that temperatures vary just as much within cities,” says Monica Turner, a professor in the department of Integrative Biology, Wisconsin-Madison University and a co-author of the study.With climate change making extreme heat events more common each summer, city planners are working on how to prepare. Heat waves drive up energy demands and costs and can have big human health impacts. One potentially powerful tool, the study's authors say, are organisms that have been around long before human civilizations could appreciate their leafy benefits. And those trees may be the secret to keeping the places we live livable.Essentially, says Turner, roads, sidewalks and buildings absorb heat from the sun during the day and slowly release that heat at night. Trees, on the other hand, not only shade those surfaces from the sun's rays, they also release water into the air through their leaves, a process that cools things down.To get the maximum benefit of this cooling service, the study found that tree cover must be more than 40 percent. In other words, an aerial picture of a single city block would need to be nearly half-way covered by a leafy green network of branches and leaves.12. What can we infer from Paragraph 2?A. Temperatures in cities mainly depend on their green coverage.B. People living and working in cities must plant trees in summer.C. Cities are warmer than the countryside because they don't have trees.D. An area with more trees can be cooler than the other parts within a city.13. Which of the following problems is caused by extreme heat events?A. Severe damage of city facilities.B. Serious human health problems.C. Residents' growing demands for plants.D. Unnecessary waste of energy resources.14. Why are trees crucial to cities?A. They help shade and cool the cities.B. They make urban scenery beautiful.C. They build up city cooling systems.D. They essentially block and release heat.15. What can city planners conclude from the study?A. They should publish the study in a newspaper.B. They should educate citizens to protect forests.C. They should plant trees on roads and sidewalks.D. They should cover nearly half the city with trees.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

My wallet was gone. And I could only have left it one place: the G9 bus, from which I had gotten off minutes earlier and which was now speeding to some stops. The moment of realizing it was gone was followed by mental math. How much time and money would it cost to replace the credit cards, the driver's license, the expensive lipstick ($ 55!).Two hours after I was back at my house, I heard a knock on the door. My husband answered while I sat in the dining room on the phone with a credit card company. "Does Jennifer live here?" I heard someone say. In her hand was my wallet, without a penny missing. She left before I could offer my gratitude to her.After I posted the story, I heard from her boyfriend, who identified the good citizen as Erin Ball, a 26-year-old girl working for a trade organization.Once I figured out her, I called to thank her. She said she spotted my wallet and thought that it's more dangerous to go to a stranger's house than leaving the wallet with the driver, but she still decided to take the chance. "If I were in that situation, I would want someone to try to find me," she said. Ball doesn't find her actions particularly excellent. She added, "It's not hard to do small things for people."After Ball found my wallet, she decided to post a picture of my driver's license online before going to my house, trying to see if anyone knew me. No sooner had she left my doorstep than I got emails from two neighbors who recognized my face, both offering to help me find my missing property.Ball found my house on a bitterly cold night for which I was extremely grateful. Looking back, I'm not surprised someone had wanted to help a stranger. A warm current of honesty and harmony is running through this town.4.

You can potentially remember more by handwriting, according to a new study.The potential benefits of handwriting for memory have been debated for some time. The new study set out to answer one question: How does handwriting compare to using a keyboard when it comes to remembering new information?In all,24 participants took part. Researchers asked each of them to write with a pen and then each was also asked to type on a keyboard. While performing these tasks, each volunteer wore a cap that held electrodes next to their head. It looked somewhat like a hair net fitted with 256 sensors. Those sensors recorded the participants' brainwaves. The electrodes noted which parts of the brain turned on during each task. And they showed that writing turned on memory areas in the brain while typing didn't.Audrey van der Meer, the new study's leader, says this suggests that when we write by hand, we remember better. “This is because writing involves complex movements that activate more areas of the brain. The increased brain activity gives the brain more ‘hooks’ to hang your memories on,” she explains. Van der Meer also points out that writing by hand is related to visual notetaking. “Rather than typing blindly, the visual notetaker has to think about what is important to write down. Then, key words can be interlinked by boxes, arrows and small drawings,” she adds.This study does not recommend banning digital devices. In fact, its authors point out, computers and otherdevices with keyboards have become necessary in modern society. Keyboarding can especially benefit those with certain special needs (such as if they have trouble using their hands) and typing beats writing when it comes to speed, they add.8. Why were participants asked to wear caps in the study?A. To record their brainwavesB. To inform them of their tasksC. To allow them to focus on writingD. To protect their heads like hair nets9. What does Audrey van der Meer try to explain?A. Why handwriting is more complex than typingB. Why the brain works when it comes to learningC. Why handwriting helps remember informationD. Why key words are helpful to visual notetaking10. What is the study's authors' view on typing?A. It relieves people's handsB. It remains vital and helpfulC. It is not worth recommendingD. It is more challenging than writing11. Which of the following can be a suitable title for the text?A. How Can You Remember New Information?B. Handwriting Benefits Health in the LongRunC. Should Typing Take the Place of Handwriting?D. Handwriting Is Better for Memory Than TypingDKenyan mother Beth Mwende heard her sleeping child cry out, but did not worry after the three-year-old quickly quietened down. The next morning, however, she found her daughter, Mercy, nearly unconscious with two bite marks in the neck. “I didn’t know that it was a snake,” Mwende said.Although snakebites are common in her hometown, antivenom medication is difficult to get. Mwende lives about 160 kilometers east of Nairobi, Kenya’s capital. So she took her daughter to a traditional healer. He placed stones over the bites. Mercy died within hours. She was one of about 700 Kenyans killed by snakebites each year, notes a report in the scientific publicationToxicon.The Kenya Snakebite Research and Intervention Center (KSRIC) is working to change that. The KSRIC hopes to have East Africa’s first antivenom medication on the market within five years. It estimates the cost will be about 30 percent of an imported product, which often sells for about US $ 30.More than 70, 000 people are bitten in East Africa each year. Climate change and deforestation are worsening the problem as snakes get pushed out of natural surroundings into populated areas.Nearly 100 snakes live at the research center in a forest near Nairobi. Researchers take venom from snakes and study it before injecting small amounts into other animals, such as sheep. The animals then create antibodies that can be made into antivenom.“Up to now, no one has made any kind of antivenom in Kenya,’’ said Geoffrey Maranga Kepha, a senior snake handler.Two effective antivenoms are available in Kenya, from India and Mexico, the center says.The center is teaching communities that using antivenom immediately after receiving a snakebite can save lives, said head researcher George Adinoh.“After seeing how people died in Kenya from snakebites I decided to devote my life to coming up with a rescue measure that will help or prevent people from dying from snakebites,” snake handler Kepha added.12.

Why did Mwende take her daughter to a traditional healer?A. She couldn’t afford any modern treatment.B. She lived where antivenom medication is not available.C. The traditional way is very effective to treat snakebites.D. She believed a traditional healer could cure her daughter.14. What is causing more snakebites to happen in East Africa?A. Lack of antivenom medication.B. Environmental damage and climate change.C. People’s low awareness of the danger of snakes.D. People’s pursuit of traditional cures for snakebites.15. What do we know about antivenom in Kenya from the text?A. Itis taken from antibodies of sheep.B. There is only one effective antivenom available.C. KSRIC is trying to develop a local antivenom now.D. People refuse to use antivenom after being bitten by snakes.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
