Answer 1

保证答案准确率！

1.A
for many years = since many years ago，常用作现在完成时句子的时间状语

1. A
it's necessary that从句中，从句必须使用虚拟语气，即从句谓语动词由“should + 动词原形”构成，由此排除B；
句意明显为被动，排除D；
he has refused to是he has refused to be sent to Beijing的缩写，此is后面的表语从句并不缺少其他成分，所以用that引导，而不能用what引导，排除C。

2. A
考查强调句型的特殊疑问句。
it was.... that made his daughter so absent-minded this morning是强调句型，被强调部分（即省略号部分）用what代替，并提前至从句句首，即为答案A。

3. A
they thought为插入语，做题加以忽略不计。
句意很明显要求选项指代“某人”somebody，并做从句的主语，由此排除CD。
whichever要求上下文必须有相应的选择范围，排除B。

追问

您的回答非常好！
但是晚辈还是有两处不懂。
第一，refused to 后面省略的be sent to Beijing,我是否可以认为表语从句缺宾语，从而选择what.
第二，they thought是插入语，请问老师怎么能看出来，教我下方法，谢谢。

A for many years
A. not be sent,that
A what it wasthat 其实这句最好就用what was that 或是WHAT
A. whoever
