優(yōu)質(zhì)解答

只能用 if you did sth.…因?yàn)椋?根據(jù)文法)
英文條件句有三種基本結(jié)構(gòu)：
a.現(xiàn)在式 + 將來(lái)式 If you go …I 'll go too…
b..過(guò)去式 + 現(xiàn)在條件式 If you went…I would go too…
c.過(guò)去完成式 + 過(guò)去條件式 If you had gone… I would have gone too…
必須熟記,不能亂用.
你的句子明顯屬于第二種,故只能用 I would appreciate it if you did sth.……
另外,你寫(xiě)的 if you could do sth.…不妥,要不去掉 would,要不改為 have done ,即前面的第三種句型.
望對(duì)你有所幫助.
