Question

— ________ times a week do you go to the library?
— Twice a week.

A．How long

B．How soon

C．How often

D．How many

Answer 1

D

試題分析：句意：—一周你去圖書館多少次？—每周兩次。How long 多長時(shí)間，  how soon多長時(shí)間以后  how often 多長時(shí)間一次how many多少，后跟復(fù)數(shù)名詞。從語境中可看出，問多長時(shí)間一次，如果沒有times a week,要用how often,它的干擾性很大。因此選D。
