题目内容
10.-I'll call your parents if your homework __________ before four o'clock today.-Sorry,Mr.Li.I'm doing it right now.
| A. | isn't done | B. | won't be done | C. | doesn't do | D. | won't do |
分析 句意:--如果今天四点前你的家庭作业还没有做完,我将打电话给你的父母.
----对不起,李老师,我马上就做.
解答 答案:A.这是一个时态和语态结合的句子,首先,if的用法是:当if 翻译为"如果",引导条件状语从句时,主句用一般将来时,从句用一般现在时.由此排除C,D.而从句的主语是your homework,是动作的承受者,而不是作业主动去完成,所以用一般现在时的被动语态,即am/is/are+动词过去分词.联系语境,这里指作业没被完成,所以用否定式,主语为单数homework,故用is not done.故选A.
点评 本题要想做的正确,掌握if的用法是一个重点,对时态语态的掌握是另一个重点.且必须结合题意进行选择.
