重点释解“并列句与主从复合句”
第三讲
一、并列句
[要点个个清]
1.and, not only ...but (also) ...,both ... and ... 等,表并列、顺承或递进关系
There the air is clean and the mountains are green.
那里空气清新,千山一碧。
2.but, yet, whereas等,表转折关系
The failure was a big blow to him, but he wasn't discouraged and soon got as enthusiastic as ever.
这次失败对他是个很大的打击,但他并没有沮丧,很快便像以前一样充满热情。
3.or, either ... or ..., not ... but ...等,表选择关系
Either you must improve your work or I shall dismiss you.
要么你改进工作,要么我就辞退你。
4.for, so,表因果关系。for连接的分句一般不能放在句首
The leaves of the trees are falling, for it's already autumn.
树叶在坠落,因为秋天已经到了。
5.and, or, 表条件或结果关系,常用于句型“祈使句+and/or+陈述句”中
You have to move out of the way, or the truck cannot get past you.
你得让出路来,否则卡车无法从你身旁通过。
6.while,作为并列连词,强调两种情况的对比
I love to drink black coffee while he prefers it with milk.
我爱喝黑咖啡,而他更喜欢喝加牛奶的。
[名师点津]
when可用作并列连词,相当于and at this/that time,意为“正在这/那时;突然”,常用于下列句式:sb. be about to do/going to do/on the point of doing sth. when ... (某人正要做某事,这时……);sb. be doing sth. when ... (某人正在做某事,这时……);sb. had just done sth. when ... (某人刚做完某事,这时……)。
He was about to go out when the telephone rang.
他正要出去,这时电话响了。
He had just finished writing a report when the boss let him type a letter.
他刚写完一篇报告,这时老板让他打印一封信件。
[易错对对碰]
1.并列句与定语从句
防止并列句与定语从句混用:并列句由and, but等并列连词连接,句中已有连接词,这时就不能再用引导定语从句的关系词了。
①They live in a small house, in front of ______ stands an orange tree.
②They live in a small house, and in front of ________ stands an orange tree.
分析:两句的区别是连词and,句①逗号后为非限制性定语从句,空格处为引导词,表示物,故填which;句②and连接两个并列分句,空格处指代前面分句中的a small house,故填it。
③The old man has three sons, none of ______ is a doctor.
④The old man has three sons, but none of ________ is a doctor.
分析:两句的区别是连词but,句③逗号后为非限制性定语从句,空格处为引导词,表示人,故填whom;句④but连接两个并列分句,空格处指代前面分句中的three sons,故填them。
2.并列句与状语从句
辨清并列句与状语从句:并列句是连词连接两个“互不依存的主谓结构”,两者之间是并列关系;而在状语从句中前后两个句子一个是主句,一个是从句,从句是用来修饰主句的。
①______ you take the medicine, you will be all right.
②Take this medicine, ________ you will be all right.
分析:句①空格处引导条件状语从句表示“如果”,故填If;句②中两个并列分句是顺承关系,故填and。
③________ money is ne
