Question

---_____do you visit your uncle?
---once a week .

A．How long

B．How many

C．How much

D．How often

Answer 1

D

解析試題分析：how long多長、多久 ； how many 多少（對(duì)可數(shù)名詞多少進(jìn)行提問）；how much多少（對(duì)不可數(shù)名詞進(jìn)行提問）；howoften意為“多久……次、是否經(jīng)常”,用來提問在某一特定的時(shí)間進(jìn)行某個(gè)動(dòng)作的次數(shù),答語通常是always,usually,often,sometimes,once/twice a day.本句答語是once a week一周一次，所以答案是D。
考點(diǎn)：考查特殊疑問詞組的用法。
