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。
