(3)時(shí)態(tài)搭配(it = 形式主語(yǔ))

2.主語(yǔ)從句的考點(diǎn)和難點(diǎn)

(2)陳述語(yǔ)序

例句： Whether it will do good to us remains to be seen.

How the accident happened is still unknown.

Who won the game hasn't been announced yet.

(3)時(shí)態(tài)搭配(it = 形式主語(yǔ))

用it做形式主義的目的：避免主語(yǔ)過(guò)長(zhǎng)，導(dǎo)致整個(gè)句子頭重腳輕

例句： It surprises us all (that) he will come to our village tomorrow.

[考點(diǎn)]：<1>以what / whatever引導(dǎo)的主語(yǔ)從句不可以改為 it 形式主語(yǔ)的結(jié)構(gòu)；除了做連接詞外，what/ whatever還會(huì)做從句中的成分，比如主語(yǔ) / 賓語(yǔ)。(所以不可以改為 it 形式主語(yǔ)的結(jié)構(gòu))

<2> It is + 形容詞 / 名詞 / 名詞性短語(yǔ)等 + 主語(yǔ)從句

（表示重要/必要的詞/詞組，如 Important necessary A necessity）

that從句中的謂語(yǔ)動(dòng)詞一般要采用‘’should + do‘’的虛擬語(yǔ)氣形式，should的經(jīng)常省略

例句： It is necessary that we (should) learn English well.

It is highly important that we (should) fasten the belt while driving the car.
