在if和when后的從句應(yīng)該用一般現(xiàn)在時表示將來。這樣看問題其實不全面，因為if和when又同時可以是連接主句和賓語從句的從屬連詞，請看下面兩個例子：1.我不知道他明天什么時候來。Idon’tknowwhenhewillcometomorrow.2.我不知道他明天是否會來。Idon’tknowifhewillcometomorrow.以上兩個例子中when后引導(dǎo)的不是時間狀語從句，而是賓語從句，因為come是說明天發(fā)生的動作，在主句用一般現(xiàn)在時的情況下，從句依然要用willcome來表示將來的意思；if后跟的也不是條件狀語從句，而是賓語從句，所以依然要用一般將來時表示將來。IV.我們?nèi)绾闻袛鄆f和when后面的句子到底是賓語從句還是狀語從句。從以下兩個方面來考慮：1、因為狀語從句的位置可以變化，它既可以放在主句，也可以放在主句；而賓語從句的位置只能跟在主句的謂語動詞例如：Wewillvisittheparkifitdoesn’traintomorrow.=Ifitdoesn’traintomorrow,wewillvisitthepark.（所以這個復(fù)合句中if引導(dǎo)的從句為條件狀語從句。）IwillbeateacherwhenIgrowup.=WhenIgrowup,Iwillbeateacher.（所以這個復(fù)合句中when引導(dǎo)的從句為時間狀語從句。）我們不能把“Idon’tknowwhenhewillcometomorrow.”說成“Whenhewillcometomorro
