v Unit6 An old man tried to move the mountains. 从属连词as soon as, so....that, unless在状语从句中的用法归纳 1.as soon as 在时间状语从句中的用法 as soon as意为“一....就...”，表示从句的动作一发生，主句的动作随即发生。as soon as引导的时间状语从句，需要用一般现在时替代一般将来时（主将从现）。主语为一般将来时或祈使句。 e.g.As soon as she graduated ,she found a good job.她一毕业就找到了好的工作。 I’ll teach you how to use it as soon as I come back.我一回来就教你如何使用它。 Tip:英语中表示“一...就...”的，相当于从属连词作用的还有：immediately,hardly...when. no sooner...than等 2.so...that在结果状语从句中的用法 在“so...that”从句中，so是副词，修饰形容词或副词。引导结果状语从句时常用以下结构： so+形容词/副词+that从句 e.g. He is so tall that I can’t touch him. 他太高了，我摸不到他。 Tips:①当“so...that”引导结果状语从句时，从句若是否定句，可与“too...to”互换。 e.g. We were so sleepy that we couldn’t do it any more. We were too tired to do it any more. ② so..that 意为”如此...以至于”，“so that”意为“结果，以至于”，两者不可相等。 e.g. The film is so interesting that all of us laughed. The film is interesting, so that all of us laughed. 3.unless在条件状语从句中的用法 Unless意为“除非“，与“if...not”可以互换，但unless语气较强。需要注意：在unless引导的从句中，谓语动词不能再用否定形式。 e.g. You will pass the exam unless you study hard. If you don’t study hard you will fail the exam. 练一练 一.根据汉语提示完成填空。 1.他们一到那里就爱上了那个地方。 They________ _______ _______ _______ the place______ soon ______ they got there. 【答案】fell in love with; as;as 【解析】爱上....fall in love with ，根据“got”可知此处为过去时，fall-fell。 一...就... as soon as 2.李娜是如此出名，以至于很多人都2她。 Li Na is _____ famous ______ many people know her. 【答案】so；that 【解析】如此...以至于 so...that 3.他昨晚发生了什么事？ What ________ ______ him last night? 【答案】happened to 【解析】根据“last night”可知该题时态为过去时，某人怎么了：what happen to sb？ 4.这个男人一说完愚公就说到他们家人能够继续移山在他死后。 _____ ______ _____the man finished ________,Yu Gong said that his family could continue_____ ______the mountains after he died. 【答案】As soon as;talking;to move 【解析】一...就 as soon as；完成做某事 finish doing sth；继续做某事 continue to do sth 5.除非他将尾巴藏起来，否则他没法将自己变得像人那样。 He can’t turned himself into a man______ he can hide his _______. 【答案】unless；tail 【解析】“除非”unless；“尾巴”tail 用所给词的适当形式填空。
