1选择题
My sister ______ a teacher. She works in a primary school.
答案:B
解析:本题考查be动词的用法。主语“My sister”是第三人称单数,因此be动词应使用“is”。易错点:学生可能误选A(am)或C(are),需牢记“我用am,你用are,is连着他她它”的口诀。故选B。
2选择题
— ______ you swim when you were ten? — No, I ______. But I can swim now.
- A. Can; can't
- B. Could; couldn't
- C. Can; could
- D. Could; can
答案:B
解析:本题考查情态动词和时态。问句中的时间状语“when you were ten”(你十岁时)表明是过去的能力,应用情态动词的过去式“Could”。答句需保持时态一致,用“couldn't”表示“不能”。易错点:学生可能忽略时间状语而误选A。故选B。
3选择题
Look! The children ______ happily in the park.
- A. play
- B. plays
- C. are playing
- D. played
答案:C
解析:本题考查现在进行时。句首的“Look!”提示动作正在进行,主语“The children”是复数,因此用“are playing”。易错点:学生可能根据主语复数误选A(一般现在时原形)。故选C。
4选择题
The classroom ______ every day by the students.
- A. cleans
- B. is cleaned
- C. cleaned
- D. was cleaned
答案:B
解析:本题考查一般现在时的被动语态。主语“The classroom”是动作“clean”的承受者,且时间状语“every day”表明是经常性动作,因此用一般现在时的被动语态“is cleaned”。易错点:学生可能忽略被动语态结构,漏掉be动词,误选A。故选B。
5填空题
She ______ (go) to school by bus every morning.
答案:goes
解析:本题考查一般现在时。主语“She”是第三人称单数,且时间状语“every morning”表明是经常性动作,因此动词需用第三人称单数形式“goes”。易错点:学生可能忘记动词加-s。
6填空题
We ______ (not see) the movie yet. Let's go to see it together.
答案:haven't seen
解析:本题考查现在完成时。时间状语“yet”常用于现在完成时的否定句中,主语“We”是第一人称复数,因此用“haven't seen”。易错点:学生可能误用一般过去时“didn't see”。
7解答题
根据汉语提示完成句子:如果明天不下雨,我们将去野餐。
If it ______ rain tomorrow, we will go for a picnic.
答案:doesn't
解析:本题考查if引导的条件状语从句。在if条件状语从句中,用一般现在时表示将来。主语“it”是第三人称单数,否定形式需借助助动词“does”,后接动词原形“not rain”,缩写为“doesn't rain”。易错点:学生可能误用将来时“won't”。
8解答题
将下列句子改为被动语态:People speak English in many countries.
答案:English is spoken in many countries (by people).
解析:本题考查一般现在时的主动语态变被动语态。原句主语“People”是泛指,变被动语态时可省略。原宾语“English”变为被动语态的主语,谓语动词“speak”变为“is spoken”,介词短语“in many countries”保留。易错点:学生可能漏掉be动词“is”,或忘记将动词过去分词。
