虚拟语气题目
1 she( )come if she( )so busy.
A would have;hadn't been
B should have;hasn't been
C should ;hadn't been
D might;wouldn't be
还有图中4 5 6题

Answer 1

1 选A 意为：如果她当时不那么忙的话她就过来了。主句和从句说的都是与过去的情况相反，即实际上当时她很忙，所以那时候她没过来
对应的结构为：从句if had done，主句would have done

4 注意前面的动词demand，凡是有表示要求、建议（suggest，suggestion，proposal，recommand）、命令（order）等这类含义的动词或者名词，后面的从句（动词的话后面是宾语从句，名词的话后面多为同位语从句），谓语都需要用虚拟语气：should+动词原形，其中的should很多时候都是可以省略的
再举个例子：老师建议他多做练习：The teacher suggested that he (should) do more practice.

5 特殊句式，it is time/high time that+过去时

6 同第4题的情况，这里是省略了should。完整的应该是...necessary measures （should）be taken

追问

谢谢你
