◎ 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.
