时间状语从句课件(课堂PPT)

翻译下列句子: 你一按按钮,灯就会亮。 The lamp will light instantly you press the button. 他一出现,便一片沉寂。
Directly he appeared ，there was dead silence.
4. 另外还要注意（一……就……） hardly …(had done ) when …( did ) scarcely … when … no sooner … than … (放句首则倒装） e.g. I had hardly/scarcely got home when it started to rain.
5> 在将来时的从句中常用when, 且从句必
须用一般现在时。
You shall borrow the book when I have
finished reading it. 6> when还用在表示 “一……就……”的
句型中。 Hardly/Scarcely had I entered my room when the telephone rang.
原因状语从句中应注意的问题
as, because, for, since 的区别 1> as作为从属连词引导原因状语从句时,语气 不如because 强烈。它引导的从句常放在 句首, 说明原因, 后面的主句则说明结果。 2> because 引导从句时, 语气最强, 直接回答 why的问句。她引导的句子是语意中心所 在, 一般在句后。 (最强答why）
当主从句动作同时发生, 且从句动作
为延续性动词时, 三者可互换。 When/While/As she was making a phone call, I was writing a letter.

If you study hard, you will pass the exam. (如 果你努力学习，你会通 过考试的。)

A. whenever B. until C. while D. wherever
② 如果主句谓语动词是瞬间动词，则用否定式的主 句表示“直到…才”。
如：I didn’t go to bed until (till) he came back. 3) ---Was his father very strict with him when he was at school?
3、原因状语从句：
通常由连词：because, as, since, now that引导。
注意： ① 在强调句中强调原因状语从句，只能用because引导， 不可用as或 since，如：
It was because he was ill that he didn’t go with us. ② because可以引导表语从句,而 as, since不可以， 这时状语一 般都是it, this, that
(3)before “在…之前” Before I came downstairs I had prepared myself very carefully for what I must say.
*如果before引导的从句位于主句之后，有时不能译
成“在…之前”，而要译成“就”、“才” 等。如： The struggle lasted four years before the North won in the end. He almost knocked me down before he saw me.
1) Someone called me up in the middle of the night, but they hung up ____ I could answer the phone.(’00全国） A. as B. since C. until D. before
