When it was near midnight， the rain stopped and people started to go out. When I walked slowly to the door， I found a boy sleeping on the floor. He had no shirt on， and held a small bag made of clothes in his arms. I shook him softly so that I woke him up. He jumped up and opened his eyes wide before he realized it was me. He opened the bag hurriedly， gave me my shoes， and said sorry to me shyly. He was waiting here all the time although we didn't know each other. I was deeply moved. I paid him and said goodbye to him. Then I put on my shoes and walked home， thinking about the boy in my mind.

并列连词
and 和 but 但是 or 或者，否则
so 因此，所以 while 然而 yet 但是
both…and… ……和……都；
既……也…… either…or… 或者……或者……；
不是……就是……
not only…but also… 不但……而且…… neither…nor… 既不……也不……
并列连词both…and…，either…or…，not only…but also…和neither…nor…的辨析

大卫既喜欢英语，又喜欢数学。
Both Beijing and Guangzhou have traffic problems.

辨析 例子
2. either…or…意为“或者……或者……；不是……就是……”，表示在两者之间进行选择。连接句子两个主语时，谓语动词采取“就近原则” He will come either on Saturday or on Sunday.
他不是在周六就是在周日来。

考点二：
从属连词if的用法
辨析 例子
if引导条件状语从句，它表示的意思是“假如，如果”等。在复合句中如果主句用一般将来时或者为祈使句或使用情态动词时，则if引导的状语从句用一般现在时（主将从现） If it doesn't rain，we will go to the park next Sunday.
如果下周星期天不下雨的话，我们将去公园。

从属连词when，while的用法：when，while都有“当……时候”的意思。
考点三：
辨析 例子
when既可表示某一点时间，也可以表示某一段时间。在when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，可与主句中的谓语动词同时发生，也可在其后发生 I was just reading a book when she came into my room. 她走进我房间时，我正在看书。
Were you writing when the teacher came in？
老师进来的时候，你在写信吗？
while只能表示某一段时间，不能表示某一点时间。在while引导的时间状语从句中，其谓语动词只能是延续性的，而且也只能与主句中的谓语动词同时发生或存在 While Jim was mending his bike，Lin Tao came to see him. 正当吉姆修自行车时，林涛来看他。
Jenny is doing her homework while Simon is watching TV. 西蒙在看电视的时候，珍妮在做家庭作业。
1. while引导的时间状语从句多用进行时态，主从句的动作都是进行时的时候只能用while。
I was doing my homework when my mother came back home yesterday evening.
昨天晚上妈妈回家的时候，我正在做家庭作业。
While/When I was doing my homework，my mother came back home yesterday evening.
昨天晚上当我正在做家庭作业的时候，妈妈回家了。

孩子们正在跑步，这时他们听到了摩托车的声音。
He is strong while his brother is weak. 他长得结实而他弟弟却很瘦弱。

并列连词and和or在“祈使句＋and/or＋简单句”句式中的运用。
1. “祈使句＋and＋简单句” 与 “If you…，you'll…” 同义。
　Work hard，and you will pass the exam. 努力学习，你会通过考试。
＝If you work hard，you will pass the exam. 　
如果你努力学习，就会通过考试。
＝If you don't work hard，you won't pass the exam. 　
如果你不努力，就不会通过考试。
2. “祈使句＋or＋简单句”与“If you don't…，you'll…”同义，其中or意为“否则”。
Hurry up，or you will miss the bus. 　
快点，否则你就错过公交车了。
＝If you hurry up，you won't miss the bus. 　
如果你快点，就不会错过公交车了。
＝If you don't hurry up，you will miss the bus. 　
如果你不快点，就错过公交车了。
状语从句在复合句中起状语的作用，修饰主句中的谓语动词、形容词或副词。状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用。根据意义可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、条件状语从句、结果状语从句、让步状语从句、比较状语从句。
考点四：
状语从句
1. 时间状语从句
引导时间状语从句的连词有：when，before，after，while，since，as，till，as soon as，until等。
（1）when 当……的时候
when引导时间状语从句时，表示主句的动作与从句的动作是同时发生的，或者从句的动作发生在主句之前的。可表示“一段时间”或“时间点”。
eg. She was reading a book when I called her.
我打电话给她时，她在看书。
（2）while 当……的时候
while引导的时间状语从句只能表示一段时间（与延续性动词连用），不能表示时间点（不可与非延续性动词连用）
eg. While she was doing her homework，her mother was doing the cooking.
她做作业时，她的妈妈在做饭。
I came in while he was watching TV. 　他看电视时，我进来了。
（3）until＝till 直到
until，till引导的时间状语从句时，主句与从句都是肯定句，主句的谓语动词为延续性动词。当主句用否定句，从句用肯定句，主句的谓语动词为非延续性动词，即是not…until…结构，意为“直到……才……”，常可以与after，before进行句型转换。
eg. I will stand here until your father comes back. 　
我会站在这儿等你爸爸回来。
He didn't go home until he finished his homework.
＝He went home after he finished his homework.
直到做完作业，他才回家。
（4）as soon as 一……就……
eg. I will tell him about this as soon as he comes back.
他一回来，我就告诉他这件事情。
注意：不管主句是用一般将来时，还是一般现在时，或主句是祈使句时，时间状语从句都用一般现在时，不能用一般将来时。
I will tell him the news when he gets back tomorrow. 　
当他明天回来时，我会告诉他这个消息。
2. 条件状语从句
引导条件状语从句的连词或短语有： if，unless＝ if… not（除非……，如果不……）；as long as（只要） 。
What will you do if it rains tomorrow？ 如果明天下雨，你将干什么？
You will fall behind others unless you work hard. ＝You will fall behind others if you don't work hard.
你会落后于别人，除非你努力学习。
As long as you help us， we will finish the task on time.
只要你帮助我们，我们就会按时完成任务。
注意：主句用一般将来时，从句要用一般现在时表示一般将来时（主将从现）。
3. 地点状语从句
地点状语从句用连词where和wherever引导。
She follows him wherever he goes. 　他无论到哪里她总跟着。
4. 原因状语从句
引导原因状语从句的连词有：because（因为），since（既然），as（由于）等。
◇because表示事情发生的直接原因。
He didn't come to school today because he was ill. 　
因为他病了，所以没上学。
◇since意为“既然，因为”，since从句表示显然的或已知道的理由。
Since everybody is here，let's begin our meeting. 既然大家都在这儿，让我们开始我们的会议吧。
◇as引导原因状语从句，意思是“由于”，表“双方已经知道的原因”，与because相比，较口语化，只是对结果的附带说明，所表达的原因语气较弱。
As the weather is so bad， we have to delay our journey.
因为天气太糟糕，我们不得不推迟旅游。
5. 比较状语从句
引导比较状语从句的连词有：than，as…as…，not as…as…等。

English is as important as Chinese. 　英语与语文一样重要。
6. 结果状语从句
引导结果状语从句的连词有：so…that…．，such…that…，意思都是“如此……以致……”，so之后接形容词或副词，such之后接名词。
◇ so＋ 形容词/副词＋that…
◇ such ＋ 名词＋ that…
◇ so many/few＋可数名词复数＋that…
◇ so much/little＋不可数名词＋that…
eg. The girl is so young that she can't go to school.
女孩太小，以致不能上学。
He is such a kind teacher that we all like him.
他是如此好的老师，以至我们都喜欢他。
注意：so…that…可以和too…to…，not…enough to…句型转换。
eg. The box is so heavy that we can't move it. ＝The box is too heavy for us to move.
＝The box is not light enough for us to move.
这个箱子太重，我们搬不动。
7. 目的状语从句
引导目的状语从句的连词有：so that，in order that 等。从句in order that 可以用in order to do sth. 来转换。
　I sit in the front of the classroom so that I can hear the teacher clearly.
＝I sit in the front of the classroom in order that I can hear the teacher clearly.
＝I sit in the front of the classroom in order to hear the teacher clearly.
我坐在教室的前面为了能听清楚老师说的话。
8. 让步状语从句
引导让步状语从句的连词有：although，though，even though，even if，和no matter…短语等。
Although he is young，he knows a lot. 尽管他年轻，但他懂很多。
注意：（1）though与but；because与so 不能出现在同一组主从复合句中，二者只能取其中一个。
Although he is young，he knows a lot. ＝He is young but he knows a lot.
no matter 短语有：no matter what＝whatever，no matter when＝whenever，no matter who＝ whoever，no matter where＝ wherever
（2）让步状语从句不能用一般将来时，要用一般现在时表示一般将来时。
9. 注意：when和if在宾语从句与条件状语从句时的时态问题。when和if引导宾语从句时，后接的从句该用什么时态就用什么时态；引导条件状语从句，后接的从句用一般现在时表将来时。如：
（1）I don't know when he will come（宾语从句，他还没来，用一般将来时）. If he comes（条件状语从句），please ring me up at once. 我不知道他什么时候来。如果他来，请马上给我电话。
（2）He wonders if he will go with her this afternoon（宾语从句，他还没去，用一般将来时）. If he goes with her（条件状语从句），he will tell her by himself. 他不知道他下午是否和她去。如果他和她去，他会亲自告诉她。
