Question

Does ________ matter much if they do not come tomorrow?

A．this

B．it

C．that

D．he

Answer 1

B

試題分析：考查it的用法：為了避免頭重腳輕，it可以代替主語從句，這句話是主語從句是if they do not come tomorrow，句意：他們明天不來很要緊嗎？選B。
點(diǎn)評(píng)：主語從句能用it作形式上的主語。常以it作形式主語的句型有： A.It+be+形容詞（obvious，true，natural，surprising，good，wonderful，funny，possible，likely，certain，probable，etc.）+that從句。B.It+be+名詞詞組（no wonder，an honor，a good thing，a pity，no surprise，etc.）+that從句。C.It+be+過去分詞（said，reported，thought，expected，decided，announced，arranged，etc.）+that從句。D.It+seem，happen等不及物動(dòng)詞及短語+that從句。E.It+doesn’t matter（makes no difference，etc.）+連接代詞或連接副詞引起的主語從句。
