现在看看答案：
1.A 考的是现在完成时的特殊用法，在“it is (has been )….since”结构中，主句常用现在完成时，也可用一般时。但是在since后面要用过去时，如：It is (has been)about 7years since I came here .我来这儿近7年了。
2．C 此题考的是一般过去时的特殊用法，在“would rather、would sooner、would just as soon、might as well,would prefer(宁愿，但愿)”等后面的从句中，如表示现在或将来的动作或情况，用一般过去时。I’d rather you left now.我宁愿你现在就走。因此选C.
3．B 这是一般现在时表将来时的一种特殊用法,在时间或条件状语从句中,分句不能用将来时,要用一般现在时代替将来时,例:Unless you get rid of smoking,you will not stay healthy你只有戒烟,方可保持健康.When you come next time,I’ll show you around our campus.你下次来时,我将带你到我们的学校去看看.
