英语中的强调句型 it is/was...that/who... 中的that、who可以省略吗？最好有详解。

Question

His writing is so confusing that it's difficult to make out what it is he is trying to express.
这是安徽省2011年高考题，为什么what it is后面没有that?这不是强调句吗？

Answer 1

强调句的基本句型：It is / was + 被强调的句子成分 + that / who + 句子的其他成分。

who可以用that代替，但是that不能用who代替，更不能省略，这是句型的构成的条件。

It was Doctor Smith that (who) gave us a lecture last week.上周给我们讲课的正是史密斯博士。

It was last summer that my daughter learned to swim.正是去年夏天我女儿学习游泳了。

Answer 2

不可以，强调句中的这两个连词是绝对不能省略的。追问

追答

这个不是强调句。
首先一个so...that 句型，这个你应该看明白了。
接下来是个it is + adj+to do的句型
what it is he is trying to express 这是个定语从句，本来的句子应该是：he is trying to express is what，it 这里是个代词代替he is trying to express.这句话的；由于这个句子又要做make out 的宾语从句，把本来的特殊疑问句 what is it？变成了宾语从句的陈述语序，就出现了what it is

追问

what it is he is trying to express 我觉得这个是宾语从句吧，做make out 宾语；如果是定语从句，没有先行词。

追答

嗯，我理解错误了。应该是这样理解才对，it作为形式主语代替后面的句子he is trying to express,那么这个宾语从句就是 what he is trying to express is.

Answer 3

it is/was +被强调部分＋that/who+其他
现在时态用is,过去时态用was;被强调部分是人that和who都能用，被强调部分是物只能用that. 注意强调句不能强调谓语部分。下面举例
I lost my watch in the park last week.
这句话 主语I 谓语lost 宾语my watch 地点状语 in the park 时间状语 last week
强调主语可以改为 It was I that/who lost my watch in the park last week.
强调宾语 It was my watch that I lost in the park last week.
强调地点状语It was in the park that I lost my watch last week。
强调时间状语It was last week that I lost my watch in the park。
