题目内容
4.I'm waiting for my friend.If she ______,I'll go shopping alone.( )| A. | doesn't come | B. | comes | C. | won't come |
分析 我在等我的朋友,如果她不来,我就一个人去购物.
解答 答案:A
首先根据句中的go shopping alone(独自去购物)推断,前面if引导的条件状语从句的意思是"如果她不来"本句考查if引导的条件状语从句,在含有条件状语从句中的复合句中,如果主句中用一般将来时,从句使用一般现在时表将来,一般现在时的构成是:主语+动词原形/动词的第三人称单数形式;且从句中主语she是第三人称单数形式,再根据句意"如果她不来",应该用doesn't后加动词原形come为doesn't come.故选A.
点评 做本题的关键是正确判断从句的类型,并熟练掌握对状语从句中时态方面的要求.
