Question

Will was stupefied with exhaustion, and he _____ his head on the grass under one of the trees and slept, but he saw a cat acting strangely. 

A．should have lied

B．ought to have lay

C．might have laid

D．must have laid

Answer 1

C

試題分析：句意：Will過(guò)度勞累，他本來(lái)可能已經(jīng)將頭枕在樹(shù)下的草地上睡著了，但是他看見(jiàn)一只貓走過(guò)來(lái)。這里表示對(duì)過(guò)去的事情的不太肯定的推測(cè)，用might have done，should have done是虛擬語(yǔ)氣“過(guò)去本應(yīng)該做卻沒(méi)有做”，ought to have done和should have done意思一樣，也是“過(guò)去本應(yīng)該做卻沒(méi)有做”，must have done“過(guò)去一定做了…”。所以選C。
