二、单选题
1. David, ______ you please sweep the floor and take out the rubbish
A. may B. should C. could D. must
【答案】C
解析：这是一个礼貌请求的句型。在英语中，“could” 常用来委婉地提出请求或询问可能性，比起 “may”、“should” 和 “must” 更为合适。“May” 虽然也是礼貌的但现在使用较少，“should” 是建议，“must” 是强制的意味，不适合这里的语境。
2. —Must I hand in my book report today, Mr. Brown
— No, you _______. The book report is due in two weeks.
A. can’t B. mustn’t C. shouldn’t D. needn’t
【答案】D
解析：“needn’t” 相当于 “do not need to”，意思是 “不必”。这里 Mr. Brown 在告诉学生不用今天交书面报告，因为报告的截止日期是两周后。
3. — Could I ride an electric bicycle to school
— No, you _______ . You are too young to ride an electric bicycle.
A. couldn’t B. needn’t C. can’t D. mustn’t
【答案】C
【解析】“can’t” 用于表示不可能或不被允许的行为。由于孩子年龄太小，因而 “不能” 骑电动自行车到学校。
4. Everyone wants to reach the top of the mountain, but all the happiness happens while you _____ it.
A. climb B. climbed C. are climbing D. have climbed
【答案】C
【解析】“are climbing” 表示正在攀登的过程。这个句子强调的是过程中的幸福，而不是实现目标之后的幸福，因此使用进行时态。
5. —Could you please do the dishes
—________. I cut my finger and I'm trying not to get it wet.
A. Yes, sure B. No problem C. Sorry, I'm afraid I can't D. That would be fine
【答案】C
【解析】由于切到了手指并且尝试保持不弄湿它，所以说话者不能清洗餐具。因此选择 “Sorry, I’m afraid I can’t” 表示抱歉并解释不能做餐具的原因。
6.—Could I borrow your camera
—________, but please give it back by Saturday.
A. I'm sorry B. Of course C. Certainly not D. No, thanks
【答案】B
【解析】本题考查情景交际用语。A项用来表达遗憾，常译为“对不起”,B项表达同意，意思为“当然”，C项表达不同意，译为“当然不”，D项表达不同意，意思为“不，但同样谢谢你。”句意：—我能借借你的照相机吗？—当然可以，不过，请到周六归还。根据题意，应该是同意借了，故答案为B项。
7. —It is sunny today. __________________ taking a walk with me
—That sounds interesting.
A. Could you please B. Would you please C. Why not D. How about
【答案】D
【解析】句意：——今天天气晴朗，和我一起去散步怎么样？——听起来很有趣。Could/ Would you please do… 意为：请你做……好吗？please后跟动词原形；Why not+动词原形？意为：为何不做某事；How/What about doing sth. 意为：做某事怎么样？根据句式结构可知，应选择D。
8.—What do you usually do ________ your parents aren't at home
—I do my homework. Sometimes I watch TV or play computer games.
A. because B. while C. but D. before
【答案】B
【解析】本题考查while引导的时间状语从句，句意：—当你父母不在家时，你通常做什么？—我做作业。有时候看电视或玩电脑游戏。A项because引导原因状语从句，含义为“因为，由于”，B项引导时间状语从句，含义为“当…时候”，C项but为并列连词，含义为“但是”，D项before引导时间状语从句，含义为“在…之前”。根据题意，B项正确。
9.—Sally, could you ________ me your camera
—Sorry, Jack. Mine is broken. You can ________ Amy’s.
A. keep; borrow B. borrow; lend C. lend; borrow D. lend; keep
【答案】C
【解析】句意：——Sally，你能把你的照相机借给我吗？——抱歉Jack。我的照相机坏了。你可以借Amy的。
考查动词辨析。keep保留；borrow借入；lend借出。第一空，主语you是借出，用lend；第二空主语You是借入，用borrow。故选C。
10. — How many books can I ________ from the school library at a time
— Two. And you can ________ them for two weeks, but you can’t ________ them to others.
A. borrow；lent；keep B. lend；keep；borrow
C. keep；lend；borrow D. borrow；keep；lend
【答案】D
【解析】句意：——我一次可以从学校图书馆借多少本书 ——两本。你可以把它们保存两个星期，但不能借给别人。
考查动词辨析。borrow借入；lend借出；keep保留。根据题意，第一个空是指从图书馆借入，所以填borrow，第二个空是指你可以保留它们两个星期，所以填keep。第三个空是指借出，所以填lend。故选D。
11. —What about having a party for Bob
—I don’t think it’s a good idea. Bob ________ parties.
A. hates B. imagines C. likes D. changes
【答案】A
【解析】句意：——为Bob举行一个聚会怎么样？——我认为那不是一个好主意。Bob讨厌聚会。
考查动词辨析。hates讨厌；imagines想象；likes喜欢；changes改变。根据“I don’t think it’s a good idea”可知应是不喜欢聚会，故选A。
12. Mike doesn’t know French. And ________.
A. so do I B. so am I C. neither do I D. neither am I
【答案】C
【解析】句意：Mike不知道法语。并且我也不知道。
考查so和neither引导倒装句的辨析。so+助动词/be动词/情态动词+主语，表示“也”，即表示和上句表达的肯定内容是一样的情况；neither+助动词/be动词/情态动词+主语，表示“也不”，即表示和上句表达的否定内容是一样的情况。根据“Mike doesn’t know French.”可知此处应表达“也不”，而由“doesn’t”可知此处应用助动词，故选C。

十、阅读理解
A
Everyone has different ways of letting their kids do housework. Here are some ideas that I think would work.
Start young. Of course, when your kids are babies, your main job is to talk to them. But at the same time, letting them see you at work might help, especially when they begin to walk.
Start from some easy housework. You can give them some easy housework to do, such as washing vegetables and taking out the rubbish. And when they do a good job, you can reward them with some candies or ice-cream.
Do the housework together. Let them help you while you’re folding clothes. They can pass you the clothes. And maybe they can fold one or two of them. When you get back home from shopping, they can help you to put away your things and help to wash the dishes after dinner.
Praise them. Remember when you ask your children to help, you should make them feel as if they’re doing a great thing by praising them. You can say something like “What a strong boy you are!” or “You’re so helpful.” It will make them feel happy. And they'll be ready to help you next time.
Tell the importance of doing chores. Discuss the importance of doing chores with kids. Most parents feel it’s their children’s job to do chores by themselves. Not only help out around the house, but also to share in tasks and responsibilities as members of the family.
1. How many ways are there to make children help with housework
A. Two. B. Three. C. Four. D. Five.
2. When might children learn to help according to the passage
A. When they’re babies. B. When they’re older.
C. When they begin to walk. D. When they begin to talk.
3. What does the underlined word “reward” mean in Chinese
A. 考察 B. 对待 C. 奖励 D. 关爱
4. Which of the following is NOT true
A. When your kids are babies, you should just talk to them.
B. Washing vegetables is a kind of easy housework for children.
C. Children can help to pass you clothes while you are folding them.
D. Words like “You’re helpful” can make children feel happy.
5. What can we learn from the passage
A. How to do chores. B. How to say sorry.
C. How to let kids do chores. D. How to stay young.
【答案】1．D 2．C 3．C 4．A 5．C
【解析】文章大意：本文是一篇说明文，主要介绍了一些让孩子做家务的方法。
1．细节理解题。根据“Start young”；“Start from some easy housework”；“Do the housework together”；“Praise them”；“Tell the importance of doing chores”可知，一共介绍了五种方法。故选D。
2．细节理解题。根据“letting them see you at work might help, especially when they begin to walk.”可知，在他们开始走路的时候就要学会帮助，故选C 。
3．词义猜测题。根据“ with some candies or ice-cream”可知，这些都是对于孩子们的奖励，所以单词“reward”指的是“奖励”，故选C。
4．推理判断题。根据“when your kids are babies, your main job is to talk to them. But at the same time, letting them see you at work might help, especially when they begin to walk.”可知，当你的孩子还是婴儿的时候，你的主要工作就是和他们说话。但与此同时，让他们看到你工作的样子可能会有帮助。故选A。
5．主旨大意题。通读全文及“Everyone has different ways of letting their kids do housework. Here are some ideas that I think would work.”可知，文章主要介绍了几种让孩子做家务的方法。故选C。
B 根据短文内容从下面方框内的六个选项中选择五个还原到文中,使短文意思通顺,结构完整。
A. And they also give children a sense of responsibility, importance and confidence. B. Parents must make children understand how hard they work. C. However, the chores should suit(适合) children. D. Doing chores can help children get better grades. E. Some believe that children should not do chores. F. Perhaps more chores on weekends can be helpful.
Should parents ask their children to do chores 1 They think that children are too young to cook or clean for themselves or their parents. But many people believe that children can learn a lot from doing regular chores. Parents should help children learn to do the housework that they will have to do when they live on their own. 2
Most experts(专家) agree. 3 Parents shouldn’t, of course, ask a schoolboy to cook when he is doing his homework. If the child has activities after school, the time left to do chores may be short.
4 When a child does what his parents ask him to do happily, he will probably have the feeling of growing up. Chores can be useful. They are a teaching tool(工具). Parents use the tool to teach children so that they can care for themselves someday. 5 If parents keep a clean house, children won’t find any reason to do chores.
