Department of Homeland Security recommends having at least a two - week supply of water and food.PotatoesShelf life：2 to 5 weeks if stored in a cool, dry, dark placeYukon Gold, red, and fingerling potatoes will last from two to three weeks. Larger white potatoes can last for three to five weeks. Sweet potatoes have about the same shelf life. Don't store them next to onions, however. The two might go together well in cooking, but raw, each gives off gases and moisture that might cause the other to spoil faster.Tea※Shelf life：6 to 12 months past "sell - by" dateDried tea leaves, whether loose (in a sealed container) or in teabags (in an unopened box) can easily last a year or more if they' re not subjected to damp or humidity. However, the tea does tend to lose flavor over time.Peanuts● Shelf life：1 to 2 monthsPeanuts in their shell, especially when kept cool and dry, are perfectly happy in the cupboard for as long as two months.Canned fruits and vegetables● Shelf life：1 to 2 years past "sell - by” dateCanningis an extremely efficient means of preserving food. Generally speaking, if canned foods aren't subjected to extreme heat, their contents should stay good for two years or more. Be aware, however, of dented cans or those with swollen tops, which may indicate the presence of bacteria inside.1. Which can go bad faster if stored with onions?A. Potatoes.B. Tea.C. Peanuts.D. Canned fruits and vegetables.2. What is special about tea?A. The flavor of tea can always remain the same.B. Tea leaves are better to be preserved in an open jar.C. Tea leaves should be kept away from the state of being wet.D. The maximum length of time that tea can be stored is 6 months.3. What may shorten the "sell - by” date of canned foods ?A. Shapes of cans.B. Categories of foods.C. Decline of the temperature.D. Exposure to high temperature.BFor fishermen and sailors in the seaside town of Shangpan in Linhai, Zhejiang province, where recently 12 stranded（搁浅的）whales were found, it is not unusual to spot whales or dolphins in the sea — they would always call them haizi, or “son of the ocean”. And if the local fishermen spot such intelligent sea creatures in need, they will save them from danger without hesitation.In the recent rescue of melon-headed whales, they tried their best to help as a 37-second video of a young man sleeping in the water holding a whale soon went viral online, with netizens applauding his constant efforts and caring heart in trying to keep the whale alive. “The melon-headed whale knew I was trying to save it and would be more cooperative and wouldn’t move.” said Lu Wenhui, a 21-year-old diver from Hangzhou Changqiao Polar Ocean Park, who held up the whale’s head so it could breathe easily. Lu had been staying in the water for 10 hours by 4 a.m. Wednesday after coming for the rescue work on Tuesday, when the stranded whales were first spotted.“Whales are mammals and need to breathe in air — that’s why I had to hold its head, to ensure it could breathe smoothly the whole time,” Lu said. The stranded whales, after the struggling of being transported, were worn out when they arrived at the fish farm and might have drowned if they were left unattended.The reason why the whales were stranded is still not clear. And these stranded whales were returned to the ocean because they are not adapted to artificial breeding environments on land.4. What do local fishermen usually do after finding haizi in danger?A. Ignore them.B. Feed them.C. Transport them.D. Protect them.5. Why does the author describe Lu’s rescue work?A. To introduce the whales in detail.B. To voice his views on the diver.C.

They are used to breathing in the sea.C. They aren’t suited to artificial surroundings.D. They are fond of swimming near the seaside.7. Which of the following can be the best title for the text?A. Melon-headed Whales Were StrandedB. Rescuers Went All out to Help WhalesC. Fishermen Transported Stranded WhalesD. Witnesses Voiced Opinions on Rescue WorkCI am a part of the Windward Robotics team known as the Omnicats, one of the many clubs offered at my school. My eight teammates and I started out by watching the robotics qualifiers and finals of Chinese teams. We used these robotics videos for inspiration and drew up mind maps of what our team wanted to do.We meet every day for two hours after school in order to build our robots. Typically, adultsoverseewhat students are building, but my school lets teens take control. It leaves room for more errors, but we're prouder of our final product.Before our first real match, a practice was offered at the actual site. My sub-team had been further along than other teams but quickly fell behind. When we arrived on that big day, I immediately felt my teammates' nervousness. Our first match was in three minutes. All of us glanced around at each other since we were not prepared at all. Our robot was still sitting in a box. Two of our teammates rushed to take the robot for an official examination as the rest of us discussed our strategy (策略).Our team captain explained that we all should try driving the robot now, while it was early in the season. She gave me the remote. I had only driven for a limited amount of time in practice so I was extremely nervous. Our autonomous code (自动代码) beganto run almost immediately after our short discussion. Despite all the drama, we ended up winning the match.Not too bad for the first match! I was so proud. I did not enjoy the pressure of driving but liked building the robot behind the scenes instead.We have transferred to a different type of robotics at the end of the semester, which involves the whole team designing one giant robot with large tools. I am a part of the electrical team now, so I make sure the motherboard(母板) can supply the robot's energy needs. We have all enjoyed the rest of the season and learned that robotics it never dull!8. What does the underlined word in paragraph 2 probably mean?A. InspectB. AdmireC. OverlookD. Assume9. Why did her teammatesfed so nervous before first match?A. Because it was really too difficult for them.B. Because they didn't prepare for it at all.C. Because they didn't know what the match would be like.D. Because they didn't make full preparations before the match.10. How did the author feel about their first robotics match?A. It was tiring but exciting.B. It was stressful but wonderful.C. It was terrible but powerful.D. It was boring but professional11. What is the best title for the text?A. A Girl Who Loves RobotsB. My First Robotics MatchC. Teamwork for RobotsD. Robotics Is Never DullDIf you could travel back in time, which period of history would you visit? It’s a great question to ask your friends, and time travel is the subject of many science fiction films. Of course, sci-fi is familiar to most of us, butwhat is cli-fi? The simple answer is climate fiction which focuses on the subject of climate change.Many of the cli-fi examples we watch tend to be disaster films. It could be solar flares (太阳耀斑), ice ages devastating (摧毁) the planet, extreme flooding swamping the earth with water, or super-storms that threaten life as we know it. While films and novels of this style are often subject to the typical images of a hero or heroine battling to save the day, what sets it apart from most sci-fi films is that the plots will often draw on apparently reasonable outcomes in the near future.Climate change and the potential threats have long been established. Some believe that the issue of climate change has even led to more fans watching films to learn more about what's happening to the world – seeing it as a form of edutainment. A study conducted by the Yale programme on Climate Change Communication tested the effects that two climate fiction novels can have on its readers and found “significant positive effects” in terms of their attitudes and beliefs towards the climate crisis – for example, understanding global warming will harm themand future generations.Most climate films are not only extremely popular action films, but also cause our fear of what some see as the approaching end of the world. This sounds bad, but according to a study conducted on 310 adults in the US, watching such scary films can help us feel more prepared and less alone in situations such as the pandemic (疫情). So, it looks like cli-fi is hereto stay – and there seem to be some benefits. Whether it’s there to educate, entertain or prepare you for a climate crisis, it might have a role to play.12. Which of the following may be the subject of cli-fi?A. Time travel.B. Global warming.C. Weather forecast.D. Economic climate.13. What can we learn about cli-fi films from paragraph 2?A. They are often about extreme natural disasters.B. They want to show that man can conquer nature.C. They usually have similar plots with sci-fi films.D. They can show the true near future of the world.14. Why is the study conducted by the Yale programme mentioned in paragraph 3?A. To prove that climate change has potential threats.B. To show that people like climate fiction novels.C. To tell that cli-fi novels have positive effects on readers.D. To explain how the climate crisis affect the human being.15. What does the writer mainly want to tell us in the last paragraph?A. Cli-fi films are very popular as action films.B. A study was conducted on 310 adults in theUS.C. The pandemic make people scared and alone.D. Cli-fi films are useful and will be here to stay.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。

They say these defects result from epigenetic changes that can potentially affect multiple generations.The study, published in theAmerican Journal of Stem Cells, suggest both parents contribute to the health status of their offspring — a common sense conclusion which science is only now beginning to demonstrate, says the study's senior investigator, Joanna Kitlinska, PhD, an associate professor in biochemistry, and molecular and cellular biology.“We know the nutritional, hormonal and psychological environment provided by the mother permanently influences organ structure, cellular response and gene expression in her offspring,” she says.“But our study shows the same thing to be true with fathers — his lifestyle, and how old he is, can be reflected in molecules that control gene function,” she says. “In this way, a father can affect not only his immediate offspring, but future generations as well.”For example, a newborn can be diagnosed with fetal (胎儿的) alcohol spectrum disorder (FASD), even though the mother has never consumed alcohol, Kitlinska says. “Up to 75 percent of children with FASD have biological fathers who are alcoholics, suggesting that preconceptual paternal alcohol consumption negatively impacts theiroffspring.”Advanced age of a father is correlated with elevated rates of certain diseases, and birth defects in his children.A limited diet during a father’s preadolescence has been linked to reduced risk of cardiovascular death in his children and grandchildren. Paternal obesity is linked to enlarged fat cells, changes in metabolic regulation, diabetes, obesity and development of brain cancer. Psychosocial stress on the father is linked to defective behavioral traits in his offspring. And paternal alcohol use leads to decreased newborn birth weight, marked reduction in overall brain size and impaired cognitive function.“This new field of inherited paternal epigenetics needs to be organized into clinically applicable recommendations and lifestyle alternations,” Kitlinska says. “And to really understand the epigenetic influences of a child, we need to study the interplay between maternal and paternal effects, as opposed to considering each in isolation.”4. What’s the message the writer conveys in the passage?A. Both parents contribute to the health status of their offspring.B. Father’s age and lifestyle are tied to birth defects.C. Father plays a more critical role in birth defects.D. Birth defects can potentially affect multiple generations.5. What can we infer from the example in Paragraph 5?A. FASD can only be diagnosed in a newborn whose father is addicted to alcohol.B. A newborn will not contract FASD if his mother has never consumed alcohol.C. A father’s lifestyle can negatively impact his offspring.D. Most children have biological fathers who are alcoholics.6. Which of the following situations is less likely to lead to children’s birth defects?A. Having a father with a limited diet.B. Having a father who is an alcoholic.C. Having an overweight father.D. Having a father with psychosocial stress.7. What will the research probably continue to focus on in the part that follows?A. The maternal epigenetic influences of a child.B. The ways to avoid negative paternal influence on children.C. The clinical application of the research findings.D. The interaction between maternal and paternal effects.CAs artificial intelligence(AI) systems become more advanced, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate(模仿）the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing detailed patient information in quantities is a crucial factor for their success.One of the most important areas for influencing global health is in the field of epidemiology(流行病学）。

Miles has had some health problems. Though he had received more than thirty operations in a Jewish Hospital in New York, he would be back for more.Miles enjoyed spending his time in our VIP lounge looking at the entire wall filled with the pictures of many celebrities (名人) who often came to our office. We soon added Miles' picture to the wall among those celebrities.Among the celebrities, Miles like the country singer Garth Brooks best. Miles would just sit and stare at Garth's picture,Oneday, Mr. Brooks was waiting in the lounge for his flight. As he looked at the collection of photographs, Garth asked about the youngster with the big smile. We told him about Miles. We also told him how much Miles loved and respected (尊重) him. He nodded and left.About six months later, Garth was going to be performing in Kansas City and he asked our workers to help him get in touch with the family. He wanted Miles to be his guest. That evening, not only did Miles sit in the front row, but he and Garth also had a private meeting after the performance.Although Miles would receive many more treatments after that special evening, his smile greeted us with every following visit.

A Helpless MotherDThefirst thing we notice about new people are their faces. The next time we see these people, we remember them because we remember their faces. This seems like a simple process. However, scientists found that it is not such a simple process. The section of the brain that is responsible for face recognition seems to work differently for different people. Some people have great difficulty remembering and recognizing faces, while others almost never forget a face.Normal babies are born with a natural ability to recognize faces. In fact, their face recognition abilities are much better than their parents. Babies are most highly skilled at face recognition at six months. But by nine months, they lose this skill. By nine months, a baby’s face-recognition skills are about the same as an adult’s.Unfortunately, some people are not born with this ability to recognize faces. The part of the brain that is responsible for face recognition doesn’t work for them. This condition is called face blindness. People with very severe face blindness cannot even recognize their own faces. In fact, people with this condition can sometimes be frightened when they look in the mirror. They don’t recognize their own face, so for a second they are startled when they see this unfamiliar face.Face blindness is not always severe. Scientists believe up to 10 percent of the population may be affected by face blindness to some degree, yet many people with mild face blindness might not even know they have it. They have no reason to know they are different from anyone else until someone points it out. This is similar to people with color1 blindness. Colorblind people can’t see the difference between certain color1 s such as red and green, until someone tells them that green and red are two different color1 s.There is no cure for face blindness. So for the time being, people with face blindness need to find simple techniques to compensate for their problem. They can try to recognize people by their hairstyle, their voice, or their glasses. Hopefully, in the future as scientists learn more about this condition, they may find a cure.12. What is the first paragraph mainly about?A. The way to improve one’s face-recognition skills.B. The simple process of the brain to recognize others’ faces.C. The fact that some people have face-recognition problems.D. The importance of face recognition in human communication.13. When do children have the best face-recognition skills?A. At birth.B. Half a year old.C. Nine months old.D. In adolescence.14. What does the underlined word “startled” in the 3rd paragraph probably mean?A. Depressed.B. Confused.C. Embarrassed.D. Surprised.15. What does the author think of the problem of face blindness?A. People need to take it seriously.B. Certain techniques can make up for it.C. It will be cured in the near future.D. It has the same effect with color1 blindness.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。

Make a campfire, photograph sunset over the sea and try to absorb this charming spot with your entire being.Alaska-Bartlett Cove Campground, Glacier (冰川) Bay National ParkIn a state full of natural riches,Glacier Bayis a wonder, home to high peaks, whales, 700 miles of coastline, and light blue glaciers that flow directly into the sea. Set within temperate rainforest along Bartlett Cove, the park's only campground is impressively green and an easy jumping-off point for boat tours.Arizona-Havasupai Campground, Havasupai ReservationGetting to Havasupai is a challenge.

The new research indicates that doing enough exercise could make up for some of the unhealthy impacts of bad sleep. While the health benefits of exercise and sleep are nothing new, it's the relationship between them that is interesting in this particular study — it could even give doctors another option to suggest for patients dealing with sleep problems.“We found those who had both the poorest sleep quality and who exercised the least were most at risk of death from heart disease, stroke, and cancer,” says epidemiologist Bo-Huei Huang, from the University of Sydney in Australia.Participants were grouped into three levels of physical activity (high, medium or low) and were also given a sleep quality score from 0-5 based on the amount of shut-eye they got, how late they stayed up, insomnia, snoring and daytime sleepiness.Those with the highest risk of dying from cancer or heart disease during the study period were those with the worst quality sleep and who didn't meet the WHO recommended guidelines for exercise. That risk went down for people with poor quality sleep but who did meet the exercise guidelines.In the case of all forms of cancer, for example, those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer than those with good sleep scores who kept physically active. However, that risk just about disappeared for those who didn't score well on sleep but did score well on physical activity.For now it's not clear why more exercise might make up for poor sleep, as far as our health goes. It could be that the increased activity iscounteractinginflammation (炎症), or reducing irregularities in glucose metabolism, suggest the researchers.“Considering that physical activity is perhaps more modifiable than sleep, our study offers people more health incentives to be physically active.” says population health researcher Emmanuel Stamatakis, from the University of Sydney.4. This research is of particular interest in that ________.A. it’s in this study that exercise is known to be beneficial to sleep.B. this study offers people more health treatments to be physical active.C. it could enable doctors to cure patients of their sleeping condition.D. the relationship between exercise and sleep is updated in this study.5. Which of the following statements istrueaccording to the passage?A. Those who had the poorest sleep quality were most at risk of death from heart disease.B. Those scoring lowest on sleep and exercise scale were more likely to die from cancer.C. There’s no risk of cancer for those who didn't sleep well but did score well on physical activity.D. It's evident that in terms of health more exercise could make up for poor sleep.6. What does the underlined word in Paragraph 6 mean?A. interactingB. increasingC. preventingD. causing7. Where can this passage most probably be taken from?A. A research findings reportB. A medical examination reportC. A poor sleep study reportD. A physical activity study reportCWhen an animal species is considered endangered, it means that the International Union for Conservation of Nature (IUCN) has evaluatedit as nearly extinct, which means that a majority of its population has already died off and the rate of birth is lower than the species’death rate. Today, more and more animal and plant species are on the way to extinction because of a variety of major factors that cause a species to become endangered, and as you might expect, humans play a role in quite a few of them — in fact, the biggest threat to endangered animals is human encroachment (侵入) on their habitats.Every species needs a habitat, where an animal finds food, raises its young. Unfortunately, humans destroy animal habitats in a number of different ways: building houses, clearing forests to getlumberand to plant crops, draining rivers to bring water to those crops, and making streets and parking lots.In addition, human development pollutes the environment with all kinds of chemicals, which destroys food sources and shelters for the creatures and plants of that area. As a result, some species die out while others are pushed into areas where they can’t find food and shelters — to make matters worse, when one animal population suffers, it affects many other species in its food web, so more than one species’population is likely to decrease.Habitat destruction is the number one reason for animal endangerment, which is why conservation groups work hard to repair the effects of human developments — many non-profit groups like the Nature Conservancy are taking measures to clean up coastlines and establish nature preserves to prevent further harm to native environments and species around the world.8. A species is considered endangered________.A. when the IUCN has noticed its population changeB. when most of its population has died offC. when the species’ birth rate is close to its death rateD. when the species is losing its habitat9. What does the underlined word “lumber” probably mean?A. Gas.B. Food.C. Chemicals.D. Wood.10. What is being done to protect the endangered species?A. Calling for human development.B. Raising money.C. Establishing nature preserves.D. Educating people.11. What is the main idea of the passage?A. Habitat destruction causes animal endangerment.B. Animals die out due to environment pollution.C. Measures need to be taken to increase species.D. Non-profit groups are making great contributions.DWhen Chip heard the mail truck arriving on his sixth birthday, herushed out—not knowing that he’d come back with a treasure.Outside the house, which was decorated with birthday balloons, postwoman Shelley held a pile of boxes. One was marked with Chip’s name and a greeting for his Special day, November 5.“So,” when he came running out the door, she said, “You must be Chip!” And he said,“Yes.” She said, “Today’s your birthday?” And he started smiling. Shelley said, “So, let me see if I can find you something for your birthday.”She checked her pocket and surprised him with a gift: a dollar bill and four quarters.On this day, the 42-year-old postwoman made one little boy very happy. “He was very excited,” said his mom, Bonnie. “He came running back in the house just waving his money.” Chip is saving up to buy a Spider-man action figure.“Our family has had money problems since I lost my job. Gestures like that are valuable memories.” Her hope is that Chip and his eight-year-old sister, Bennett, will remember this when they grow up. “Not the ugly that is out there right now, but the good and the kind and the giving.”A photo of a smiling Chip and Shelley next to the mail truck has been shared widely on social media. Shelley said she was just trying to give back, because people are often nice to her eight-year-old son, Joshua.On a recent day, Chip heard the mail truck and rushed out again, this time to deliver an envelope with a thank-you card for his favorite mail carrier. Since that day, the families have kept in contact. Shelley has struggled to find someone who can take care of her son, and Bonnie has agreed to watch him at her home while his mom ison her mail route.12.
