課本中不會(huì)教你的756　是強(qiáng)調(diào)結(jié)構(gòu)還是主語從句結(jié)構(gòu)

756　是強(qiáng)調(diào)結(jié)構(gòu)還是主語從句結(jié)構(gòu)

◎ 由it作形式主語的從句結(jié)構(gòu)，辨別的方法是：如果將It is/was…that這一句結(jié)構(gòu)去掉，句子仍然成立，就是強(qiáng)調(diào)結(jié)構(gòu)，如果句子不能成立，就是由that引導(dǎo)的主語從句結(jié)構(gòu)。比較：

It is the committee's decision that has been carried out. 被執(zhí)行的是委員會(huì)的決定。（為強(qiáng)調(diào)結(jié)構(gòu)）

The committee's decision has been carried out.

It is the committee's decision that he will be in charge of the work. 由他負(fù)責(zé)這項(xiàng)工作是委員會(huì)的決定。（為主語從句結(jié)構(gòu)，it為形式主語，代替that引導(dǎo)的主語從句）

He will be in charge of the work is the committee's decision.
