Question

【題目】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】考查同位語和賓語從句。“half of_________it used to charge”是$20的同位語，即原來價格的一半是現(xiàn)在的$20；另外，of后跟名詞或名詞短語構(gòu)成介賓短語，所以，這里是賓語從句；賓語從句中的charge后面缺少賓語，所以用what來引導(dǎo)賓語從句，并充當(dāng)賓語從句的賓語，故選C。
