• A． can avoid-
• B． arrived
• C． had avoided-
• D． could have avoided

Answer 1

分析 多小心一點(diǎn)，你就可能避免這起交通事故．很幸運(yùn)你只是傷到手臂．

解答 答案D．
由句意可知本題考查虛擬語(yǔ)氣．根據(jù)后面的語(yǔ)境"It's lucky that you just hurt your arm．"可知虛擬部分是對(duì)過(guò)去事實(shí)的虛擬，因此用could+have done表示本能做（實(shí)際未做）．可將句子轉(zhuǎn)化成if引導(dǎo)的非真實(shí)條件句：If you had been with a little more care，you could have avoided the traffic accident．所以答案選D．

點(diǎn)評(píng) 本題考查虛擬語(yǔ)氣．注意掌握if條件句的虛擬有三種情況，做題時(shí)就可得心應(yīng)手．if條件句的虛擬有三種情況：對(duì)過(guò)去的虛擬，從句用had done，主句用could/would/might+have done；對(duì)現(xiàn)在的虛擬，從句用did，主句用could/would/might+do；對(duì)將來(lái)的虛擬，從句用did/were to do/should+do，主句用could/would/might+do．
