第六讲并列句和复合句教学目标:1. 掌握并列句的构成和用法。

2. 熟练掌握宾语从句的构成和基本用法。

3．熟练掌握状语从句的构成和基本用法。

—、并列句用并列连词连接起来的两个或两个以上的简单句叫做并列句。

(一)并列句的构成其结构是“简单句+并列连词+简单句”。

(二)常用的并列连词2．其他的并列连词有：then，while，when，not only...but also...,neither...。

nor，either...or，as well as等。

二、复合句复合句是由一个主句和一个或一个以上的从句构成的句子。

主句和从句都具有完整的主谓结构，主句是全句的主体，从句是主句中的一部分，不能独立存在。

根据从句在全句中的不同作用，从句可分为：宾语从句、定语从句、状语从句、主语从句、表语从句和同位语从句。

在这里重点讲解宾语从句、状语从句和定语从句。

(一)宾语从句注意：whether和if引导宾语从句时，一般情况下可以互换，但在下列情况下须用whether，不能用if。

①具有选择意义，宾语从句中有or或or not时。

例如：We really don’t know whether news is true or not．我们真的不知道这消息是否是真的。

②在介词后接宾语从句或不定式时。

例如：We are talking about whether we’ ll go back to our hometown．我们正在讨论是否回老家去。

③作discuss等词的宾语时。

例如：We discussed whether we should close the shop．我们讨论了是否应该把商店关掉。

2．宾语从句的语序宾语从句无论是陈述句、一般疑问句或特殊疑问句意义，一律用陈述句语序，即“主语+谓语”结构。

句尾标点符号取决于主句。

例如：Are you a student? He asks．→He asks if you are a student．他问你是否是学生。

Where does he work? Do you know?→Do you know where he works?你知道他在哪工作吗?3．宾语从句的时态(二)状语从句1．时间状语从句①时态：当主句是一般将来时态或祈使句或含有将来的意义时，由when，as soon as，till／until，before引导的时间状语从句用一般现在时。

例如：As soon as he returns home，I’ ll let you know．他一回到家，我就告诉你。

②引导词：由when，while，as，since，after，before，until／till，as soon as等连词引导。

Father was waiting for me when I got home yesterday．昨天我到家时，爸爸正在等我。

While we were having a meeting，my sister came in to ask for me．正当我们开会时，我妹妹进来找我。

She sang happily as she walked along the lake．她一边沿着湖边走，一边欢快地唱着歌。

I didn’t go to bed until／till he came back at ll o’ clock last night．直到他昨晚11点回来我才睡觉。

Please Wait here until I come back．请在这等，直到我回来。

c)since引导的从句，表示“自……以来”，从句中的谓语动词表示动作的起点，要用一般过去时，主句的谓语动词表示延续性动作，通常情况下使用现在完成时。

在句型“It i s／hasbeen...since+从句”中，从句用一般过去时，主句用一般现在时或现在完成时。

例如：It is ten years since she joined the army．她参军已有十年了。

2．条件状语从句①条件状语从句由if(如果)，as long as(只要)，unless(除非)等引导。

如果主句为祈使句、一般将来时或含有情态动词时，从句用一般现在时。

例如：If it SNOWS tomorrow，we will have a day or two off．如果明天下雪的话，我们将放假一两天。

We won’t go to his party unless he invites us．如果他不邀请我们的话，我们就不去参加他的晚会。

②if的用法3．结果状语从句①结果状语从句由so，so...that...，such...that...，so that等引导。

例如：It is so cold outside that nobody will go out to play．外面很冷，以至没有人愿意出去玩。

He is such a good man that we all like him．He is so good a mall that we all like him．他是一个大好人，我们都喜欢他。

4．原因状语从句原因状语从句由because，as，since等引导。

如果是直接原因，通常用because引导；如果原因是人们已知的事实，用since引导；如果原因和理由是不言而喻、为人所知的、显而易见的，用as引导。

由since，as引导的原因状语从句，一般位于主句之前。

例如：Jim didn’t go to school yesterday because he was ill．吉姆昨天没去上学，因为他病了。

Since we are middle school students，we should listen to our teachers．既然我们是中学生，我们就应该听老师的话。

5．目的状语从句目的状语从句由so that，so，in order that等引导。

从句中常用can，could，may，might 等情态动词。

例如：My father gets up early every day so that he can catch the first bus．爸爸每天都起得很早，以便能赶上头班车。

6．让步状语从句让步状语从句由although，though等引导。

意思为“虽然(尽管)……但是……”，要注意不能与but用在同一个句子中。
