________ was expected，only five people turned up at the party，________ disappointed the hostess very much.

C．It；that	D．It；which

Answer 1

A
解析　在非限制性定語(yǔ)從句中，當(dāng)從句置于句首時(shí)，或從句意為“正如……”時(shí)，只能用as而不能用which來(lái)引導(dǎo)從句。C項(xiàng)和D項(xiàng)中第一空若要用it，則應(yīng)把前半句改為“It was expected that only five people turned up at the party”此時(shí)it作形式主語(yǔ)。第二空是which引導(dǎo)的非限制性定語(yǔ)從句，且在從句中作主語(yǔ)。
