Question

【題目】By the age of thirteen, Jay Greenberg _______ five symphonies（交響樂(lè)）.

A.wroteB.has writtenC.would writeD.had written

Answer 1

【答案】D

【解析】

句意：到13歲時(shí)，Jay Greenberg已經(jīng)寫(xiě)了五部交響樂(lè)。

考查動(dòng)詞時(shí)態(tài)。A. wrote一般過(guò)去時(shí)；B. has written現(xiàn)在完成時(shí)；C. would write過(guò)去將來(lái)時(shí)；D. had written過(guò)去完成時(shí)。根據(jù)時(shí)間狀語(yǔ)By the age of thirteen,可知句子時(shí)態(tài)用過(guò)去完成時(shí)，其結(jié)構(gòu)為had+動(dòng)詞的過(guò)去分詞，故選D。
