1．If he had come yesterday, I should have told him about it．

2．If he had not been ill and missed many classes, he would have made greater progress．

3．If you had asked him yesterday, you would know what to do now．

4．If it had rained last night, it would be very cold today．

Answer 1

答案：
解析：

1．He did not come yesterday, so I did not tell him about it． 　　2．He was ill and missed many lessons, so he did not make greater progress． 　　3．You didn’t ask him yesterday, so you do not know what to do now． 　　这是一个混合时态的句子，从句与过去事实相反，主句与现在事实相反，但是主句的现在时对从句的过去时而言是将来的情况，因此主句用过去将来时。 　　4．It didn’t rain last night, so it is not very cold today．
