一般现在时知识点梳理及经典练习(超详细)(word)

一般现在时知识点梳理及经典练习(超详细)(word)

一般现在时知识点梳理及经典练习(超详细)(word)一、一般现在时1.—How do you usually go to school?—I ________ to school on foot.A. goB. wentC. was goingD. will go【答案】 A【解析】【分析】句意:——你通常怎么去上学?——我步行去上学。

根据How do you usually go to school? 可知,此句为一般现在时,所以答语也应该为一般现在时,所以用go,故选A。

【点评】考查动词时态。

注意根据问句的动词判断句子的时态,答语与问句时态一致,分析选项选出正确答案。

2.She _____ out alone at night.A. dare not to goB. dares not goC. doesn't dare to goD. doesn't dares go【答案】 C【解析】【分析】句意:晚上她不敢一个人出去。

dare可以作情态动词也可以作行为动词,作情态动词时,后面直接跟动词原形,没有人称与数的变化,构成否定时直接在dare 后加not,作行为动词时后跟动词不定式,构成否定需要助动词,故答案是C。

【点评】考查dare的用法,注意dare做情态动词和行为动词的用法上的区别。

3.If he _____ the money, he _____ a lot of clothes.A. has; will buyB. had; boughtC. had; would buyD. had; will buy【答案】 A【解析】【分析】句意:如果他有钱,他会买许多衣服。

if引导的时间状语从句遵循主将从现的原则,即主句用一般将来时,从句用一般现在时,从句主语是he,动词用三单形式,have有,其三单是has,主句用一般将来时,其结构为will+动词原形,buy买,动词原形,bought是buy的过去式,故选A。
