Question

【题目】We choose this hotel because the price for a night here is down to $20,half of_________it used to charge.

A.that B.which C.what D.how

Answer 1

【答案】C

【解析】考查同位语和宾语从句。“half of_________it used to charge”是$20的同位语，即原来价格的一半是现在的$20；另外，of后跟名词或名词短语构成介宾短语，所以，这里是宾语从句；宾语从句中的charge后面缺少宾语，所以用what来引导宾语从句，并充当宾语从句的宾语，故选C。
