Question

－_______ do you practice dancing every day?
－For two hours.

A．How long	B．How often
C．How much	D．How many

Answer 1

A

試題分析：A.多長(zhǎng)時(shí)間 B.多久一次 C.多少 D.多少。句意：—你每天花多長(zhǎng)時(shí)間練習(xí)舞蹈？—兩小時(shí)。故選A
點(diǎn)評(píng)：how long指多長(zhǎng)時(shí)間，主要用來對(duì)一段時(shí)間如（three days, four weeks 等)提問，也可詢問距離；how often指每隔多久，主要用來對(duì)頻度副詞或狀語(yǔ)(如once a week等)提問；how many用來修飾可數(shù)名詞的復(fù)數(shù)，它的句式是:How many+復(fù)數(shù)名詞+一般疑問句＋? ；how much用來修飾不可數(shù)名詞，表示數(shù)量，也可單獨(dú)使用。
