问题补充：

the flight to New York will be put off is I’m especially worried about.

A. Why; what

B. Whether; what

C. How; that

D. When; that

答案：

A. Why; what

(答案→)B. Whether; what

C. How; that

D. When; that

解析：考察从句连词的选择。第一空为主语从句，从句中不缺少成分，根据句意可知，此处需要填写是否的意思，第二空是表语从句，从句中缺少about的宾语，所以选择what

,句意为这个去纽约的航班是否会被推迟是我特别担心的。
