Question

--The mistake_____, I had been more careful.
---But you weren’t at that time.

A．might have avoided	B．would avoid
C．would be avoided	D．might have been avoided

Answer 1

D 

試題分析：句意：--如果我更加仔細(xì)一些，這個(gè)錯(cuò)誤就會(huì)避免。--但是你當(dāng)時(shí)沒(méi)有。首先這個(gè)句子是個(gè)對(duì)過(guò)去情況的虛擬條件句，表示與過(guò)去事實(shí)相反的情況，if+主語(yǔ)+had done +其他+主語(yǔ)+should/would/could/might+have done+其他，所以排除BC，因?yàn)閙istake和avoid是被動(dòng)關(guān)系，所以選D。
