______ ( not catch) the early bus.15. Peter ________(major) in English if he ____(pass) the exams in Peking your wife,單三人稱主語,所以用goes D. will go, will go , will go If your wife _________, so will mine。例句: I will e to see you if I have time. 我有時間,我就來看你。 二、時態(tài)問題 Unless it rains, the game will be played.除非下雨,比賽將照常進行。s go out for a walk. 另外,if從句還表示不可實現(xiàn)的條件或根本不可能存在的條件,也就是一種虛擬的條件或假設,從句多用一般過去時或過去完成時。 If you fail in the exam, you will let him down.如果你考試不及格,你會讓他失望的。 If you ask him, he will help you.如果你請他幫忙,他會幫你的。 引導條件狀語從句最常用的連詞是if,由if引導的條件狀語從句表示在某種條件下某事很可能發(fā)生。:if(如果)、unless(除非)或 as long as(只要)等。unless在意思上等于if...not。 一、條件狀語從句用法如: 如: If I were you, I would invite him to the party.如果我是你,我會邀請他參加聚會。三 如果 if 條件句談論的是重復發(fā)生和預示要發(fā)生的情景和事件,則主從句大多用一般現(xiàn)在時態(tài)。 if 既可以引導條件狀語從句,表示“如果”,也可以引導賓語從句,表達“是否”。.
