兩種可能：1 He said that he would come if his work WAS over before 5:00 pm.(一般過(guò)去時(shí)) 2 He said that he would come if he HAD FINISHED his work before 5:00 pm.(過(guò)去完成時(shí)) 3 He said that he would hav...the teachear said he would fail me if i don't work harder.中為什么主語(yǔ)是過(guò)去將來(lái)時(shí)，而從句用一般現(xiàn)在時(shí)。有主語(yǔ)是過(guò)去將來(lái)完成時(shí)，從句是過(guò)去完成時(shí)的情況嗎？你好。不管這一句是從哪里來(lái)的，The teachear said he would fail me if i don't work harder.是錯(cuò)句。應(yīng)該是：The teachear said he would fail me if i didn'twork harder.--------注意，時(shí)態(tài)必須保持一致。真的錯(cuò)了，必須保持一致嗎？這是《新概念英語(yǔ)2》的句子有主語(yǔ)是過(guò)去將來(lái)完成時(shí)，從句是過(guò)去完成時(shí)的情況嗎？1是《新概念英語(yǔ)2》課文，還是中國(guó)人編寫(xiě)的練習(xí)？2 有主語(yǔ)是過(guò)去將來(lái)完成時(shí)，從句是過(guò)去完成時(shí)的情況-------- she said that she would take me out to dinner IF i had finished all my homework before 6:30 pm.== she said that she would take me out to dinner IF i finished all my homework before 6:30 pm.(你自己回顧一下你所學(xué)過(guò)的英語(yǔ)時(shí)態(tài)知識(shí)吧)
