No sooner had he arrived than it began to rain. 他刚到天就开始下雨了。 5.表示“一就”的一些副词有：immediately，instantly，directly等。 Immediately the bell rang，the boys rushed out. 铃一响，男孩子们就冲出去了。,6.一些表示时间的名词词组，如the moment，each time，every time，the first time，the last time，next time，the minute，the instant等也可以用来引导时间状语从句，起连词的作用。 Every time he came，he would bring me good news. 他每一次来，都会给我带来好消息。 The first time I went to Mount Tai，I was very happy. 第一次去泰山，我非常高兴。,二、条件状语从句 条件状语从句是由if，once，as/so long as，unless，on condition that，in case等引导的。在条件状语从句中，通常用一般现在时代替一般将来时，一般过去时代替过去将来时，现在完成时代替将来完成时。,1.if和unless是最常用的条件状语从句的连接词，unless在意义上等于if.not.，并且语气较强。if可用于虚拟条件句。 You will improve your oral English if you keep on practising. 如果你坚持练习的话，你将会提高你的英语口语。 Unless he studies hard，he will never pass the examination. 他如果不努力学习，就永远不能考及格。 2.in case后接一般现在时、一般过去时或包含should的从句，为主句的动作提供理由。 Dont go out tomorrow morning in case Mr Li should come to visit you. 明天上午不要出去以防李先生来拜访你。,三、让步状语从句 让步状语从句由although/though，as，even if/though，while，whatever，no matter who/how/when等词引导。 1.although和though意义一样，意为“虽然，即使”，表示让步，一般可换用，只是although语气较重，大多置于句首。although/though引导让步状语从句时，主句中不可出现but。另外although不可当副词用，而though可以。 They are generous though/although they are poor. 虽然他们很穷，但他们很慷慨。,2.whatever，however和no matter what/how这两种形式都可引导让步状语从句，意义无差别。 Whatever/No matter what happens，we will not change our minds. 无论发生什么事，我们都不会改变想法。 However difficult/No matter how difficult the work is，we will try our best to finish it in time. 无论工作多么困难，我们都要尽全力及时完成。,3.形容词/副词/名词/动词/分词as/though可引导让步状语从句，表示强调。 Young as/though he is，he knows a lot about life. 尽管他很小，但他对生活懂得挺多。 Hard as she tried，she failed to pass the exam. 尽管她努力了，但还是没有通过考试。,注意 (1)as引导让步状语从句时，要用倒装结构，动词或现在分词放在句首，谓语要加助动词do，does，did或will等；作表语的单数可数名词置于句首时，其前不加冠词。 Fail as he did，he would never give up. 尽管失败了，他也绝不会放弃。 Intelligent student as he is，he doesnt study hard. 尽管他是个聪明的学生，但他不努力学习。 (2)though引导的从句也可像as引导的从句一样使用倒装语序，但是although引导的从句只能用正常语序。,4.whether.or.引导的让步状语从句 Whether you go or not，I will go to visit my teachers. 不管你去不去，我都要去看望我的老师。 5.while也可引导让步状语从句，突出对比主句和从句所表示的两种情况。一般要位于句首。 While he is young，he is experienced. 他虽然年轻，却有经验。,单句语法填空 1. we dont stop climate change，many animals and plants in the world will be gone.(2018北京) 2. you can sleep well，you will lose the ability to focus，plan and stay motivated after one or two nights.(2018江苏) 3.If you dont understand something，you may research，study，and talk to other people you figure it out.(2017北京) 4. birds use their feathers for flight，some of their feathers are for other purposes.(2017北京),If,Unless,until,While/Although/Though,查看答案,6.My grandfather still plays tennis now and then，even hes in his nineties.(2016北京) 7. the average age of the population increases，there are more and more old people to care for.(2016天津) 8.Over time， the population grew，people began cutting food into small pieces so it would cook more quickly.(2016全国) 9. it cried，she rocked it back and forth and gave it little comforting pats.(2016四川),though/if,As,as/when,When/If,查看答案,PART 2,达标检测,当堂检测 基础达标演练,1.No matter who you are，I wont open the door. you are，I wont open the door. 2.We will not have direct contacts with you until you agree to do what we say.
