Question

Wang Fang ______ to college last year. Unfortunately, she couldn't take the examinations because of a sudden illness.

1. A.
   could go
2. B.
   did go
3. C.
   could have gone
4. D.
   must have gone

Answer 1

C
解析：
本題考查虛擬語(yǔ)氣。首先應(yīng)明確could go與could have gone所表示的時(shí)間概念。該題常錯(cuò)選A項(xiàng)或D項(xiàng)。情態(tài)動(dòng)詞(should, could, might, ought to)+不定式的完成時(shí)，表示“過(guò)去本應(yīng)該（本可以……）做某件事，而實(shí)際上并未做”的含義。情態(tài)動(dòng)詞could+動(dòng)詞原形，表示“過(guò)去將要做”或“過(guò)去能做某事”。must+動(dòng)詞不定式的完成時(shí)，表示“一定做過(guò)了”。句意為“王芳去年本可以去上大學(xué)，不幸的是，因一場(chǎng)突然的病，她未能參加考試”。
