It won't be long.”He passed the Mother again in the candy aisle. Of course, the little girl began to shout for candy. When she was told she couldn't have any, she began to cry. The mother said, “There, there, Ellen. Only a little bit longer, and then we'll be checking out.”The man again happened to be behind the pair at the check-out, where the little girl immediately began to cry for a gum and burst into a terrible anger upon discovering there would be no gum purchased today. The mother said, “Ellen, we'll be through this check out stand in five minutes, and then you can go home and have a nice nap.”The man followed them out to the parking lot and stopped the woman to compliment her. “I couldn't help noticing how patient you were with little Ellen ...”The mother broke in, “My little girl's name is Tammy...

Which word can best describe the woman?A. patientB. anxiousC. caringD. humorousCThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at home with her parents. All she’s ever wanted to do is to become an elementary school teacher. However, Hipp has racked up(累计) $100,000 (about 0.67 million yuan) in student loan debt and isn’t able to earn enough through working as a part-time skating instructor and restaurant server to live anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of adults who have been moving back in with their parents or never leaving home in the first place has been growing steadily.The Pew Research Center recently reported that 2016 was a milestone in the evolving living arrangements of young adults in the US. Until 2016, the most common living arrangement for young adults was to be living in their own property as part of a couple. UBS Financial Services, a Swiss global financial services company, released a report that even suggests one reason for the growing number of young adults still living at home could be that their f amily doesn’t want them to leave. The report shows that 74 percent of millennials (千禧一代) get some kind of financial support from their parents after college. Millennials see their parents as peers, friends and mentors. In return, their parents happily provide financial support well into adulthood, helping fund everything for them. Stuart Hoffman, chief economist for the PNC Financial Group in the US, said “Although job growth for millennials since 2014 has improved, that doesn’t necessarily mean that millen nials are starting to fly the nest, he said. “They may like living at home and being able to save money.”He added, “While it has held back household formation and purchases on things, they are probably traveling more and eating out more. I don’t know if it represents a change in moral values, it’s much more common for adult children to live in their parent’s homes because it’s becoming part of the culture.”8. What’s the purpose of Caitlin Hipp’s story?A. To prove the author’s view.B. To introduce her situation.C. To present the topic.D. To make readers rethink about the problem.9. What does the underlined part (Paragraph1) probably refer to?A. live with parentsB. live independentlyC. stay at homeD. leave home10. According to Hoffman, which of the following is true?A. It isn’t necessary for millennials to leave the nest.B. Job growth for millennials since 2004 has improved.C. Moral values are changing gradually.D. Young adults are living in a different life style.11. What’s the main idea of the passage?A. Why is the number of the millennial growing steadily?B. Why has the percentage of adults living with their parents been on the rise?C. Why are parents willing to help fund for young adults?D. Why do more adults treat their parents as peers, friends and guides?DRed wolves used to be a common sight across the southeastern United States. But today, there are just 50 left in the wild.The red wolf is one of the most endangered wild canine species（犬科动物）in the world. In the past five years, the species' population in the wild has dropped by half. The US Fish and Wildlife Service had been working for decades to reintroduce the species into the wild, but the organization recently put the program on hold.According to Cindy Dohner, the southeast regional director for the Fish and Wildlife Service, the agency is focusing on our commitment to get the science right and rebuild trust with our neighbors in those communities as we address problems regarding the recovery of the red wolf. But the animal-rights group Defenders of Wildlife said on its website that the decision made by the Fish and Wildlife Service falls well short of what is needed to continue red wolf recovery.The red wolf was declared an endangered species in 1967. By1980, it had been hunted to extinction in the wild. Some hunters thought the red wolves were coyotes（土狼）, so most people killed them because they believed wolves were dangerous and would attack people. This wrong belief has made it difficult to restore the species, because people are afraid to have red wolves reintroduced near human communities.Experts say that one way to fight these fears is simply to teach people about red wolves. In reality, they are shy animals that they don't get close to humans and hunt mostly at night. According to the Fish and Mildlife Service, captive breeding centers in the US are home to about 200 red wolves. But without continued efforts from the government and private groups, red wolves will continue to suffer.12. The underlined phrase "put...on hold" in Paragraph 2 probably means “”.A. pausedB. promotedC. overlookedD. accomplished13. What does Defenders of Wildlife think of the Fish and Wildlife Service's decision?A. Practical.B. Annoying.C. Satisfactory.D. Disappointing.14. The trouble in reintroducing red wolves near human communities lies in__ __.A. humans' over-huntingB. fears in human beingsC. shortage of food in the wildD. lack of governmental support15. What can we know about red wolves from the text?A. They don't hunt in the daytime at all.B. Their total population in the world is only 50.C. They keep away from humans due to shyness.D. They are dangerous because they attack people.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

Which word can best describe the woman?A. patientB. anxiousC. caringD. humorousCThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at home with her parents. All she’s ever wanted todo is to become an elementary school teacher. However, Hipp has racked up(累计) $100,000 (about 0.67 million yuan) in student loan debt and isn’t able to earn enough through working as a part-time skating instructor and restaurant server to live anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of adults who have been moving back in with their parents or never leaving home in the first place has been growing steadily.The Pew Research Center recently reported that 2019 was a milestone in the evolving living arrangements of young adults in the US. Until 2019, the most common living arrangement for young adults was to be living in their own property as part of a couple. UBS Financial Services, a Swiss global financial services company, released a report that even suggests one reason for the growing number of young adults still living at home could be that their family doesn’t want them to leave. The report shows that 74 percent of millennials (千禧一代) get some kind of financial support from their parents after college. Millennials see their parents as peers, friends and mentors. In return, their parents happily provide financial support well into adulthood, helping fund everything for them. Stuart Hoffman, chief economist for the PNC Financial Group in the US, said “Although job growth for millennials since 2019 has improved, that doesn’t necessarily mean that millennials are starting to fly the nest, he said. “They may like living at home and being able to save money.”He added, “While it has held back household formation and purchases on things, they are probably traveling more and eating out more. I don’t know if it represents a change in moral values, it’s much more common for adult children to live in their parent’s homes because it’s becoming part of the culture.”8. What’s the purpose of Caitlin Hipp’s story?A. To prove the author’s view.B. To introduce her situation.C. To present the topic.D. To make readers rethink about the problem.9. What does the underlined part (Paragraph1) probably refer to?A. live with parentsB. live independentlyC. stay at homeD. leave home10. According to Hoffman, which of the following is true?A. It isn’t necessary for millennials to leave the nest.B. Job growth for millennials since 2004 has improved.C. Moral values are changing gradually.D. Young adults are living in a different life style.11. What’s the main idea of the passage?A. Why is the number of the millennial growing steadily?B. Why has the percentage of adults living with their parents been on the rise?C. Why are parents willing to help fund for young adults?D. Why do more adults treat their parents as peers, friends and guides?DRed wolves used to be a common sight across the southeastern United States. But today, there are just 50 left in the wild.The red wolf is one of the most endangered wild canine species（犬科动物）in the world. In the past five years, the species' population in the wild has dropped by half. The US Fish and Wildlife Service had been working for decades to reintroduce the species into the wild, but the organization recently put the program on hold.According to Cindy Dohner, the southeast regional director for the Fish and Wildlife Service, the agency is focusing on our commitment to get the science right and rebuild trust with our neighbors in those communities as we address problems regarding the recovery of the red wolf. But the animal-rights group Defenders of Wildlife said on its website that the decision made by the Fish and Wildlife Service falls well short of what is needed to continue red wolf recovery.The red wolf was declared an endangered species in 1967. By1980, it had been hunted to extinction in the wild. Some hunters thought the red wolves were coyotes （土狼）, so most people killed them because they believed wolves were dangerousand would attack people. This wrong belief has made it difficult to restore the species, because people are afraid to have red wolves reintroduced near human communities.Experts say that one way to fight these fears is simply to teach people about red wolves. In reality, they are shy animals that they don't get close to humans and hunt mostly at night. According to the Fish and Mildlife Service, captive breeding centers in the US are home to about 200 red wolves. But without continued efforts from the government and private groups, red wolves will continue to suffer.12. The underlined phrase "put...on hold" in Paragraph 2 probably means “”.A. pausedB. promotedC. overlookedD. accomplished13. What does Defenders of Wildlife think of the Fish and Wildlife Service's decision?A. Practical.B. Annoying.C. Satisfactory.D. Disappointing.14. The trouble in reintroducing red wolves near human communities lies in__ __.A. humans' over-huntingB. fears in human beingsC. shortage of food in the wildD. lack of governmental support15. What can we know about red wolves from the text?A. They don't hunt in the daytime at all.B. Their total population in the world is only 50.C. They keep away from humans due to shyness.D. They are dangerous because they attack people.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

一、现代文阅读（36分）（一）论述类文本阅读（本题共三小题，共9分）阅读下面的文字，完成1-3题。
所谓文学，就是以言达意的一种艺术。
言所以达意，然而意决不是完全可以言达的。
因为言是固定的，有迹象的；意是瞬息万变，飘渺无踪的。
言是散碎的，意是混整的。
言是有限的，意是无限的。
以言达意，好像用断续的虚线画实物，只能得其近似。
文字语言固然不能全部传达情绪意旨，假使能够，也并非文学所应希求的。
一切艺术作品都是这样，尽量表现，非惟不能，而也不必。
《论语》：“子在川上曰：‘逝者如斯夫，不舍昼夜!'”几句话决没完全描写出孔子说这番话时候的心境，而“如斯夫”三字更笼统，没有把当时的流水形容尽致。
如果说详细一点，孔子也许这样说：“河水滚滚地流去，日夜都是这样，没有一刻停止。
世界上一切事物不都像这流水时常变化不尽么? 过去的事物不就永远过去决不回头么? 我看见这流水心中好不惨伤呀！……”但是纵使这样说去，还没有尽意。
而比较起来，“逝者知斯夫，不含昼夜!”九个字比这段长而臭的演义就值得玩味多了!陶渊明在《归园田居》用四十字把乡村风景描写得多么真切!然而仔细观察起来，乡村景物还有多少为陶渊明所未提及。
从此可知文学上我们并不以尽量表现为难能可贵。
在音乐里面，我们也有这种感想，凡是唱歌奏乐，音调由洪壮急促而变到低微以至于无声的时候，我们精神上就有一种沉默肃穆和平愉快的景象。
《琵琶行》里形容琵琶声音暂时停顿的情况说，“别有幽愁暗恨生，此时无声胜有声”，这就是形容音乐上无言之美的滋味。
英国诗人济慈在《希腊花瓶歌》也说，“听得见的声调固然幽美，听不见的声调尤其幽美”，也是说同样道理。

一、现代文阅读（36分）（一）论述类文本阅读（本题共三小题，共9分）阅读下面的文字，完成1-3题。
所谓文学，就是以言达意的一种艺术。
言所以达意，然而意决不是完全可以言达的。
因为言是固定的，有迹象的；意是瞬息万变，飘渺无踪的。
言是散碎的，意是混整的。
言是有限的，意是无限的。
以言达意，好像用断续的虚线画实物，只能得其近似。
文字语言固然不能全部传达情绪意旨，假使能够，也并非文学所应希求的。
一切艺术作品都是这样，尽量表现，非惟不能，而也不必。
《论语》：“子在川上曰：‘逝者如斯夫，不舍昼夜!'”几句话决没完全描写出孔子说这番话时候的心境，而“如斯夫”三字更笼统，没有把当时的流水形容尽致。
如果说详细一点，孔子也许这样说：“河水滚滚地流去，日夜都是这样，没有一刻停止。
世界上一切事物不都像这流水时常变化不尽么? 过去的事物不就永远过去决不回头么? 我看见这流水心中好不惨伤呀！……”但是纵使这样说去，还没有尽意。
而比较起，“逝者知斯夫，不含昼夜!”九个字比这段长而臭的演义就值得玩味多了!陶渊明在《归园田居》用四十字把乡村风景描写得多么真切!然而仔细观察起，乡村景物还有多少为陶渊明所未提及。
从此可知文学上我们并不以尽量表现为难能可贵。
在音乐里面，我们也有这种感想，凡是唱歌奏乐，音调由洪壮急促而变到低微以至于无声的时候，我们精神上就有一种沉默肃穆和平愉快的景象。
《琵琶行》里形容琵琶声音暂时停顿的情况说，“别有幽愁暗恨生，此时无声胜有声”，这就是形容音乐上无言之美的滋味。
英国诗人济慈在《希腊花瓶歌》也说，“听得见的声调固然幽美，听不见的声调尤其幽美”，也是说同样道所谓无言，不一定指不说话，是注重在含蓄不露。
