Question

9．-_____do your parents take exercise，William？
-Less than three times a week．（　　）

• A． How long
• B． How much
• C． How soon
• D． How often

Answer 1

分析 William，你父母多久進(jìn)行一次鍛煉？--一周不到三次．

解答 答案：D 根據(jù)答句"Less than three times a week"（一周不到三次），可知回答的是父母做運(yùn)動(dòng)的頻率．詢(xún)問(wèn)頻率用how often．how long提問(wèn)時(shí)間段；how much提問(wèn)價(jià)格和不可數(shù)名詞的數(shù)量；how soon提問(wèn)多久之后．故選D．

點(diǎn)評(píng) 本題考查疑問(wèn)詞組．如果答句是three times，那么就應(yīng)該用how many times提問(wèn)．注意頻率和次數(shù)的區(qū)別．
