情景导读:为了让彼得在家里能表现好,妈妈为他制定了家庭规则。让我们看一看吧。
Peter is a good student at school. But sometimes he is not a good boy at home. He doesn't like to do housework. He often makes a mess in his room. He watches TV too often. He reads in bed and he goes to bed very late. Peter's mother writes some home rules for him:
Home Rules
You should:
1. help to do housework.
2. keep your room clean.
3. go to bed early.
You shouldn’t:
1. get up late.
2. watch TV too often.
3.read in bed.
重难点
You should go to bed early. 你应该早点儿睡觉。
原 我想要买一辆摩托车。
知识点1
You should.建议对方应该做某事 You should+动词原形+其他.
点拨:本句为含有情态动词should的肯定句,后面跟动词原形,共同构成谓语。
例句:You should work hard.你应该努力工作。
拓展:should引导的一般疑问句,用来询问意见。
例句: Should I go to bed early 我应该早点儿去睡觉吗?
You shouldn't read in bed. 你不应该在床上看书。
知识点2
You shouldn't.建议对方不应该做某事
You shouldn't+动词原形+其他.
点拨:本句为含有 should的否定句。shouldn't为should not的缩写形式,意为“不应该”。
例句:You shouldn't copy the homework. 你不应该抄袭作业。
But sometimes he is not a good boy at home. 但是有时他在家不是一个好孩子。
点拨:sometimes意为“有时”,为频度副词,一般情况下放于主语之后,实义动词之前,be动词之后。为了强调也可放于句首或句尾。
例句:He sometimes goes shopping with his mother.
他有时和他的妈妈一起购物。
He is sometimes late for school. 他有时上学会迟到。

小试牛刀
— I feel tired every morning.
— You ______ go to bed earlier. It’s good for you.
A. could B. should C. would D. might
答案:B
解析:
本题考查情态动词 should 的用法。句子表达建议对方“应该做某事”,符合知识点中“You should...”的结构。其他选项中:
A. could(表示能力或请求许可) C. would(表示意愿或委婉请求)
D. might(表示可能性)均不符合语境。
— ______ I take an umbrella It’s cloudy outside.
— Yes, you should. It might rain.
A. Should B. Must C. Will D. Can
答案:A
解析:
本题考查 should 引导的一般疑问句,用于询问意见(知识点拓展)。句子询问“是否应该带伞”,符合语境。其他选项中:
B. Must(表示“必须”,语气过强) C. Will(表示将来时)
D. Can(表示能力或请求许可)均与题干中“征求意见”的语境不符。
— My eyes hurt after playing video games for hours.
— You ______ play for so long. It’s bad for your eyes.
A. shouldn’t B. can’t C. mustn’t D. won’t
答案:A
解析:
本题考查 shouldn’t 的用法,表示建议对方“不应该做某事”。题干中给出“长时间玩游戏对眼睛不好”,符合否定建议的语境。其他选项中:
B. can’t(表示“不能”,强调能力或可能性) C. mustn’t(表示“禁止”,语气过强)
D. won’t(表示“将不会”,与建议无关)均不符合题意。
— ______ I eat too much candy
— No, you shouldn’t. It’s unhealthy.
A. Should B. Can C. Must D. May
答案:A
解析:
本题考查 should 引导的一般疑问句,询问是否应该做某事。答句用“shouldn’t”否定建议,因此问句需用 Should。其他选项中:
B. Can(询问能力或可能性) C. Must(表示“必须”,与答句矛盾)
D. May(请求许可,与健康建议无关)均不符合语境。
— Is your brother late for school
— Yes, he ______ late.
A. sometimes is B. is sometimes C. sometimes be D. is some times
答案:B
解析:
本题考查 sometimes 的位置。频度副词 sometimes 应放在 be 动词(is)之后。选项 B 符合语法规则。其他选项中:A. sometimes is(顺序错误,应放在 be 动词后)
C. sometimes be(语法错误,主语为第三人称单数,需用 is)
D. is some times(拼写错误,正确形式为 sometimes)均不符合要求。
My sister ______ forgets to bring her lunch. She needs to be more careful.
A. always B. never C. sometimes D. usually
答案:B
解析:
本题考查频度副词 sometimes 的含义。题干中“需要更小心”暗示“偶尔忘记”,因此选 sometimes。其他选项中:
A. always(“总是”,与“需要更小心”矛盾)B. never(“从不”,不符合逻辑)
D. usually(“通常”,与语境不符)均无法准确表达“偶尔”的含义。
— When will you visit your grandparents
— I plan to visit them ______ next summer. Let’s go together!
A. sometimes B. sometime C. some time D. some times
答案:B
解析:
本题考查 sometime 的用法,表示“某个时间点”。题干中询问“何时去”,答句需用 sometime 表达不确定的将来时间。其他选项中:
A. sometimes(“有时”,表示频率) C. some time(“一段时间”,强调时长)
D. some times(“几次”,表示次数)均不符合“某个时间”的语境。
It took me ______ to solve the math problem. It was really difficult!
A. sometimes B. sometime C. some time D. some times
答案:C
解析:
本题考查 some time 的用法,表示“一段时间”。题干中“解决数学题花了我……”需用 some time 描述时间长度。其他选项中:
A. sometimes(“有时”,与时间长度无关)B. sometime(“某时”,表示时间点)
D. some times(“几次”,表示次数)均无法表达“花费一段时间”的含义。
