由lest,for fear that,in case 引起的从句中多使用should 表达与事实相反 1.与现在相反：使用[过去时]：I wish I were not here!(一般现在一般过去) Suppose we were not here.He loved me as if I were his own son.(一般现在一般过去) Hope I weren't always losing things!(现在进行过去进行) If only/If I hadn't been there!(现在完成过去完成) What if I hadn't been waiting right here!(现在完成进行过去完成进行) 常考句型：It's (high) time (that)…; would rather (that)… 这两个从句,只能表达对现在的看法,所以,从句中只有一般过去时.2.与过去相反：过去完成时； How nice it is if I had past the test!How nice it is if I had slept a little more this morning!3.与将来相反?将来的事情没有发生,所以只能推测.If it rains tomorrow,we'll have to stay one day more.
