Question

【題目】By the end of last term, we ________ over two thousand new words.

A. have learnedB. learnedC. had learned

Answer 1

【答案】C

【解析】

句意：到上學(xué)期末，我們已經(jīng)學(xué)了兩千多個(gè)新詞了。A. have learned現(xiàn)在完成時(shí)；B. learned一般過(guò)去時(shí)；C. had learned過(guò)去完成時(shí)。by+過(guò)去的時(shí)間點(diǎn)，表示“到過(guò)去某一時(shí)刻為止”，要求句子用過(guò)去完成時(shí)，表示“在此之前已經(jīng)發(fā)生的動(dòng)作”，即“過(guò)去的過(guò)去”。故選C。
