Question

-_______do you spare time to visit your parents every month?
-Twice.

A．How long

B．How often

C．How soon

D．How fast

Answer 1

B

試題分析：考查特殊疑問詞。根據(jù)下文的twice，說明是對(duì)頻率進(jìn)行的提問。故使用how often, how long是對(duì)一段時(shí)間進(jìn)行提問。How soon是對(duì)將來時(shí)進(jìn)行提問。故B正確。
點(diǎn)評(píng)：how long是對(duì)一段時(shí)間進(jìn)行提問。How soon是對(duì)將來時(shí)進(jìn)行提問。How often是對(duì)頻率的提問。在平時(shí)要多加辨析和識(shí)記。
