Question

【题目】_________ the flight to New York will be delayed is _________ I’m especially worried about.

A. If; what B. Whether; that

C. When; that D. Whether; what

Answer 1

【答案】D

【解析】

试题分析：考查名词性从句。Whether引导主语从句whether the flight to New York will be delayed.意为：去纽约的航班是否被推迟；what引导表语从句what I’m especially worried about并在句中做宾语。故选D。
