1.It is the book____I am looking for .A that B which C whom D how_英语解答

1.It is the book____I am looking for .A that B which C whom D how
为什么只选择A对,而B不对,这里A,B不都行吗?that在定语从句中用法是怎样?
2.It certainly is .或I'll certainly be more careful.而不是It's certainly.副词修饰动词放在动词后面才对呀.怎么 certainly全在be动词前面?就它特殊?

解答

It is...that 这是固定句型
必须用that
certainly
当然
这不是一般的表示程度的副词
就看作是修饰整个句子好了
而不是修饰某个动词.
