In late September or early October, falling fruits as hard as baseballs threaten the skulls (头骨) of you, your children, your neighbors and those that reside next door to them. Umbrellas in the yard are a must while dining in early August, and as for me, I wear my bike helmet while working in the garden.The black walnut also releases a chemical substance through its roots as a competitive strategy. It’s poisonous to several common plants. There have been many new plant varieties tha t I brought home with hopes that maybe the black walnut would accept them, but they failed toflourish.What does work are native plants that naturally grow in the area. Native plants are important to have around since they provide beneficial pollinators (传粉者) like birds, bees and butterflies with seeds and contribute to a healthy and biodiverse environment. Native plants for this area are generally easy to grow, so they experience less stress.Have I thought of getting rid of this giant pain in my tiny backyard? Yes, however, getting rid of this tree standing at 50 feet with an 87-inch trunk is next to impossible. It’s also protected under the law. Rightfully so. Trees are important to the urban forest and for all of those that inhabit it.Sometimes I think about my life without the black walnut. I can’t imagine a spring without the birds who arrive every year and loudly sing their songs before dawn. I’d miss falling asleep on lazy weekend afternoons as I look up into its leaves.Every spring, I wonder what the season holds: What are the chances of being knocked unconscious while barbecuing? Like any good relationship, I’ll never be pleased. I’m stuck with this tree, so I’ll listen to its needs and give it the space it requires. In return, my walnut offers a habitat for wildlife and a reminder.19.Why does the author wear a bike helmet while working in the garden?A. To protect the injured skull.B. To prevent herself from sunburn.C. To avoid being hit by the nuts.D. To reduce the chance of getting bitten by bees.20.What is the tree’s survival strategy?A. It attracts beneficial pollinators.B. It lets out poison to drive away pests.C. It produces a chemical fatal to some plants.D. It competes for nutrition with similar species.21.Which of the following DOESN’T account for the author’s love-hate relationship with the tree?A. The volume of its fruits may bring inconvenience.B. The tree outcompetes the native plants in the garden.C. The tree is home to numerous birds and other creatures.D. The presence of the tree takes up much space of the garden.22.The author most probably got a reminder from the tree that ________.A. it’s better to give than to takeB. trees and plants have their own ways to flourishC. even a good relationship is not always trouble-freeD. acceptance, instead of resistance, is the better way to beCIt was raining like nothing before when Ehdaa Bujeldain, an English teacher living with her family in the mountains of Derna in eastern Libya , heard a loud noise that sounded like an explosion (爆炸). Later they learned that a dam (大坝) in Derna had broken down under the pressure of running water. For the next four days, they had no power or internet, and it was only recently that they started to fully understand of the damage caused by the floods.“Half of the city has been destroyed. My mom’s relatives, my friends, my coworkers ——they are all gone. Now we, the survivors, are just ghost s in shells,” says Bujeldain, whose sadness can be easily told from her blank expression.Five days have passed since the terrible flooding in Derna, Libya’s Red Crescent organization estimated that 11,300 people have died, while the city’s mayor believes the number of deaths could be as high as 20,000.Derna is a coastal city with a seasonal river called the Wadi Derna. Despite the abnormally heavy rain, people living near the river had little warning before the floodwaters came rushing in on that terrible morning. United Nations aid chief Martin Griffiths described the scale of the flood as “appalling” (令人惊骇的) and blamed the flood partly on sudden climate change.Now international aid teams are arriving in Derna, but they face challenges due to damaged roads, lack of access to power, water, and fuel. Tarhoni, doctor of the rescue team, warns that the most difficult weeks lie ahead. “One disaster is done and there is another to come,” he says. “The thousands and thousands of people who lost everything these people now need comfort, they need company, t hey need psychological support.”23.What do we know about Bujeldain’s family from paragraph 1?A. The explosion they heard led to the destruction of the dam.B. Bujeldain saved her family from the floods with her bravery.C. Bujeldain immediately recognized the outbreak of the floods.D. For several days, they didn’t fully realize the seriousness of the floods.24.What does Bujeldain mean by saying they are “just ghosts in shells” in paragraph 2?A. They run out of energy and are very tired.B. They feel lucky as they are safe and sound.C. They are completely saddened and shocked.D. They are sorry for the loss of their homeland.25.According to the passage, which of the following does NOT contribute to the loss of lives?A. The absence of warning.B. The extraordinary rainfall.C. Unexpected climate change.D. The damage to environment.26.What might be the main focus of international aid efforts in Derna?A. Addressing mental problems.B. Providing immediate medical care.C. Conducting climate change research.D. Rebuilding roads and access to resources.DBy the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.At the heart of the phenomenon lie tiny microorganisms (微生物) in the ocean called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colorful patterns at the ocean surface. Ocean color varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.Phytoplankton live at the ocean surface, where they pull carbon dioxide into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate (调控) the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3C, it found that multiple changes to the color of the oceans would occur. The model projectsthat currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions more suitable for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing.” she said, “but the type of phytoplankton is changing.”And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to live on.” Those kinds of changes could affect the food chain.Whatever color changes the ocean experiences in the coming future will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happe ning because of climate change,” Dutkiewicz said, “but the change in the color of the ocean will be one of the early warning signals that we really have changed our planet.”27.What are the first two paragraphs mainly about?A. The cause of the changes in ocean color.B. The various patterns at the ocean surface.C. The way light reflects off marine organisms.D. The efforts to fuel the growth of phytoplankton.28.What does the underlined word “vulnerable” in Paragraph 3 probably mean?A. beneficialB. sensitiveC. significantD. unnoticeable 29.What can we learn from the passage?A. Dutkiewicz’s model aims to project phytoplankton changes.B. Phytoplankton have been used to control global climate.C. Phytoplankton play a declining role in the ecosystem.D. Oceans with more phytoplankton may appear greener.30.What is the main purpose of the passage?A. To explain the effects of climate change on oceans.B. To assess the consequences of ocean color changes.C. To introduce a new method to study phytoplankton.D. To analyze the organization of the ocean food chain.The Chubby Diaries creator is part of a community of larger-bodied travelers who are showing the world that they can do anything. Following them helps because you can be like, “Oh, this place works with larger bodies.” 31 .Second plane seats and belt extendersSouthwest is one of the few airlines to offer plus-size passengers a free second seat. To ensure the extra space, Southwest recommends booking both seats beforehand, then making a request to get your money back. 32 Southwest states: “The armrest is t he definitive gauge (测量仪) for a customer of size. If you’re unable to lower both armrests, you need a second seat.” Even if your frame fits between the lowered arms, you may still need a seat-belt extender.33 .Finding size nclusive tripsFor Natalie Robinson, ziplining (压缩) in Costa Rica determined her bucket list. “Literally for the last 10 years, that’s all I talked about,” said the co-owner of Fat Girls Travel. 34 . Her fortunes changed completely on an August trip to Costa Rica, when a friend found an outfitter without weight restrictions. The guide said Robinson could dash through the rainforest as long as she could reach the starting point high in the tree tops.35When researching a trip, ask about weight restrictions as well as the availability of equipment that can accommodate your size. If you have concerns, bring your own equipment. Plus-size travelers emphasize the importance of being self-sufficient. Finding special clothes and equipment can be challenging in unfamiliar destinations.A. Pack your own equipmentB. Find supportive travel groups and tripsC. Their extra efforts are paying off as they discover how to travel comfortably andconfidentlyD. Ziplining provides much convenience for those fat girlsE. Many airlines use the armrests to determine whether a passenger requires more spaceF. Air-lines provide this extra piece of equipment free, and you can request it at the time ofboardingG. But ziplining generally has a weight limit, so she hadn’t been able to do itYou might say I found marathoning, step by step. Or perhaps it found me. I was 36 an athlete growing up. In fact, I have a hard time 37 that term to myself even today.It started when I joined a group of women in my neighborhood for a daily three-mile walk. At first it was 38 . But soon, my body adjusted and I wanted 39 . Before long, I was running 5 miles. Then I set a goal to run a half marathon. And I did complete the Covered Bridges Half Marathon. I thought, “Now what?” I started to 40 a marathon.It so happened that I 41 a meeting one night and listened to the speaker and coach, Rick Muhr, and was so 42 by his words. I told him that I had signed up for the Ocean State Marathon, just a week away, and that I really didn’t believe I could 43 . Rick locked eyes with me and said, “Trish, you’ve done enough training. You’ll finish!”I never had someone 44 me like that, let alone a real, live coach. He gave me the45 I needed. I set out to run my 46 marathon and completed it in 4:25:00. Little did I know that this would be the beginning of nearly a decade of marathon and distance running. Running a marathon isn’t for everybody. But it is for anybody, anybody who wants to47 the unreachable and to take that 48 into the rest of their life.

She also taught Rachel a deep love for books. As a quiet child, Rachel liked to read and write stories. At a very early age, she decided she wanted to be a writer some day. Her st ory first appeared in a children’s magazine when she was ten years old.Her first books, Under the Sea Wind came out in 1941. In 1948, Miss Carson began working on another book, The Sea Around Us. She always remembered carefully when she wrote. She collected information from more than one thousand places to write The Sea Around Us. When the book came out in 1951, it won the National Book Award. It was No. 1 on the bestseller list for more than a year. The Sea Around Us made Rachel Carson famous.Rachel Carson’s most famous book, Silent Spring came out in 1962. In this book, she pointed out that the use of some kinds of pesticides(杀虫剂) like DDT would cause the number of birds to decline because it would kill them as well. Finally, in November 1969, the United Sates government decided that the use of DDT must stop in two years.Rachel Carson has been regarded as a great environmentalist(环保主义者) and writer. She will be remembered by the world.24. Rachel Carson had a deep love for nature and books because of ____________ .A. her fatherB. her motherC. her schoolteacherD. her brother25. Rachel decided that she wanted to be a writer when ___________ .A. she was very youngB. she was in collegeC. she became a teacherD. she became famous26. The Chinese meaning of the word ”decline” in this passage is probably “___________” .A. 增加B. 减少C. 维持D. 翻番27. Which of the following is NOT true according to the passage?A. Rachel Carson was a careful and serious writer.B. The Sea Around Us won the National Book Award.C. In Silent Spring Rachel said some pesticides were bad for the environment.D. The use of DDT was stopped as soon as the book Silent Spring came out.CA Koala Isn’t a BearKoalas remind people of teddy bears. They have thick fur and large ears. Their broad, flat nose makes them look cute, similar to teddy bears. In fact koalas aren’t cute. They have sharp teeth and very sharp claws! Koalas are marsupials. This means the mother carries her baby in a pocket while it develops, similar to a kangaroo. The baby koala lives in its mother’s pocket for the first six months of its life.The name “koala” comes from a native Australian word that means “no drink”. The koalas get almost all their water from the eucalyptus(桉树)leaves they eat. That’s where they get their food too. Koalas eat only eucalyptus leaves, and only the leaves of certain eucalyptus trees. The eucalyptus trees are where the koalas live. It’s also where they sleep. Koalas sleep about nineteen hours a day!Why do they sleep so much? Some people think it’s because they’re lazy. But koalas aren’t lazy. They sleep so much because there isn’t much nutrition in eucalyptus leaves. Koalas store hardly any fat, so they must save their energy. One way to do this is to move slowly and sleep a lot.After a day of sleeping they like to move around and eat just after sunset. They live alone most of the time. Koalas are very protective of their trees. If a koala sees another koala eating in its favorite tree, it might tell the other koala to leave by “barking” at it. Koa las do “talk” to each other. Besides barks, the males make a deep grunting sound.The mothers and babies talk in soft clicking sounds. If they get scared they may scream like a baby.28. According to the article, how are koalas and kangaroos alike?A. They both have thick fur.B. They both have sharp teeth.C. They both eat eucalyptus leaves.D. They both carry their young in a pocket.29. The word “koala” comes from a word that means ________.A. no drinkB. moving slowlyC. large earsD. barking loudly30. Why do koalas sleep a lot?A. Their babies need to get much rest.B. They get tired from playing so much.C. Their food does not give them much energy.D. They do not like to be awake when it is warm.31. If an adult koala screams like a baby, he may get ________.A. worriedB. scaredC. hungryD. sleepyDThere are thousands of products of all colors and shapes in a supermarket, making you believe that they are worth a try. How? Packaging is the silent but persuading salesman.There on the shelves, each bottle, can, box, and jar has been carefully designed and measured to speak to the inner self of the consumer(消费者), because he/she is buying not only a product but also his/her belief in life. Scientists have studied consumer behavior recently and found that the look of the package has a great effect on the “quality” of the product and on how well it sells, because “consumers generally cannot tell between a product and its package. Many products are packages and many packages are products.”, as Louis Cheskin, the first social scientist studying consumers’ feelings for packaging, noticed.Colors are one of the best tools in packaging. Studies of eye movement have shown that colors draw human attention quickly. Take V8 for example. For many years, the bright red color of tomatoes and carrots on the thin bottle makes you feel that is it very good for your body. And the word “green” today can keep food prices going up.。
