状语从句与并列句

状语从句与并列句

状语从句与并列句状语从句(Adverbial Clause)和并列句(Compound Sentence)是语法中的两种常见句子结构。

它们不仅具有不同的特点,而且在句子中扮演了不同的语法角色。

本文将详细介绍状语从句和并列句的定义、特点和使用方法。

状语从句的特点状语从句是一个从属从句,它用来修饰主句中的动词、形容词或副词,并提供了更多的背景信息或条件。

状语从句通常由连词引导,比如when(当),while(当...时),if(如果),although(尽管)等。

下面是一些例句:1. When I arrived home, it started to rain.(当我到家的时候,开始下雨。

)2. Although she was tired, she continued working.(尽管她很累,她还是继续工作。

)3. If you study hard, you will pass the exam.(如果你努力学习,你会通过考试。

)可以看出,这些状语从句提供了额外的信息,使得整个句子更加完整、具体。

并列句的特点并列句是由两个或多个独立的子句组成的句子,这些子句平等地并列在一起,通过逗号、分号或者连词来连接。

并列句的结构如下:[独立子句1],[连词] [独立子句2]。

常见的并列连词有and(和)、but(但是)、or(或者)等。

下面是一些例句:1. I like playing basketball, and my sister likes playing tennis.(我喜欢打篮球,我姐姐喜欢打网球。

)2. It was raining heavily; therefore, we decided to stay at home.(雨下得很大,所以我们决定呆在家里。

)3. You can either come with us, or you can stay here.(你可以跟我们一起去,也可以留在这里。

高中英语语法:并列句和状语从句常见的并列连词1. and和or◆and的用法如下:(1) 表示另加:其意为“和”“又”“而且”。

如:☞Let me have some toasts and a cup of coffee. 给我来几片烤面包和一杯咖啡。

(2) 表示结果:意为“因此”,与so的用法比较接近。

如:☞He fell heavily and broke his arm. 他摔得很重,手臂都摔断了。

(3) 表示条件:相当于if…then,含有“如果……那么……”的意味。

如:☞Do that again and I’ll call a policeman. 你再这样做我就要叫警察了。

(4) 表示连续:既可表示一种连续不断的状态,也可以表示一个动作完成之后连续做另一个动作。

如:☞The train ran faster and faster. 火车开得越来越快。

☞He finished lunch and went shopping. 他吃完午饭而后去买东西。

(5) 表示对比:含有“尽管……还”的意味。

如:☞Tom’s 15 and still sucks his thumb. 汤姆15岁了,还嘬大拇指。

◆并列连词or要比and用法简单此,它主要表示选择,其意为“或”“还是”等。

如:☞It’s a lovely baby. Is it a boy or a girl? 宝宝真可爱,是男孩还是女孩?☞He speaks French, or perhaps he understands it. 他会讲法语,或者他懂法语。

另外,or还可以表示一种否定的条件,相当于if…not…如:◆Be careful, or you’ll break that vase! 小心,否则你会把那花瓶打碎。

=If you don’t be careful, you’ll break that vase.2. 表对比或转折的连词主要有but和yet(1) but的用法:其意为“但”“但是”“却”。

如:☞He looked around but could see nobody. 他向四周望望,却没看见什么人。

☞I know of the town but I’ve never been there. 我知道有这座城市,但从未去过。

(2) yet的用法:其意也表示“但是”“却”,与but用法相似,有时可换。

如:☞It is strange yet true. 这很奇怪,却是真实的。

☞I have failed, yet I shall try again. 我失败了,但我还要尝试。

3. 表因果关系连词主要有for和so(1) for的用法:表示原因,意为“因为”“由于”。

如:☞The days were short, for it was now December. 白天很短,因为现在已经是12月。

注意:for表示原因时,它引出的句子不能放在句首,如不能说:For it was now December, the days were short.(2) so的用法:表示结果,意为“所以”“因此”。

如:☞It’s very cold, so wear a heavy coat. 外边很冷,因此穿一件厚大衣吧。

注意:汉语可以说“因为……所以……”,但英语中表示结果的so不能与表示原因的because连用,如不能说:Because it’s very cold, so wear a heavy coat.4. 其他并列连词除上面提到的并列连词外,还有both…and, either…or, neither...nor, not only...but also等并列连词。

如:(1) both…and的用法:意思是“不仅……而且”“……和……”。

如:☞He speaks both English and French. 他既说英语也说法语。

☞Both brother and sister are college students. 兄妹俩都是大学生。

(2) either…or的用法:意思是“要么……要么”“……或是……”。

如:☞We can have either fish or beef. 我们可以吃鱼或是牛肉。

☞We can either fly there or go by train. 我们可以坐飞机去也可坐火车去。

(3) neither...nor的用法:意思是“既不……也不”。

如:☞He neither drinks nor smokes. 他既不喝酒,也不抽烟。

☞She felt neither frightened nor sorry. 她既不感到害怕也不感到遗憾。

(4) not only...but also的用法:意思是“不仅……而且”。

如:☞Not only men but also women were chosen. 不仅仅是男的,女的也有被选中的。

【名师点睛】“祈使句+and/or+陈述句”结构(1)祈使句+ and(then,and then)+陈述句在这个句型中,前边祈使句+ and(and then)相当于if引导的条件句。

如:☞Come early,and you’ll catch the first bus.=If you come early,you’ll catch the first bus.来早点,你就能赶上第一班汽车。

☞Use your head,then you’ll find a way.开动脑筋,那么你就会找到办法。

☞One more word,and I'll get angry with you.如果你再说一句话,我就生你的气了。

☞Another week,and the railway station will be completed.再有一周,火车站就完工了。

(2)祈使句+(or,or else,otherwise)+陈述句在这个句型中,前边祈使句+(or,or else,otherwise)相当于unless引导的条件句。

如:☞Work hard,otherwise,you’ll fail. = Unless you work hard,you’ll fail.努力干,要不,你会失败的。

☞Use your head,o r else you won’t find a way.= Unless you use your head, you won’t find a way.开动脑筋,否则,你就找不到办法。

巧选and, or:选择连接词,只看陈述句,and叫人心欢畅,or的后果不好尝so用作并列连词时主要表示结果,意为“因此”“所以”。

如:☞I was tired, so I went to bed earlier. 我累了所以早点睡了。

☞He took my shoes, so I couldn’t leave the house. 他把鞋拿走了,我出不了门。

☞It was very cold, so we had to wear warm clothes. 天气很冷,所以我们得穿暖和的衣服。

按英语习惯,表示结果的so不能与表示原因的because套用,在使用时只能保留其中的一个。

如:那是一个难题,所以我最后才回答。

误:Because that was a difficult question, so I answered it last.正:That was a difficult question, so I answered it last.正:Because that was a difficult question, I answered it last.易错点2 but与although/though的混用汉语中可说“虽然……但是……”,但按英语习惯,通常不能说although…but或though…but:虽然很危险,但我要试试。

误:Although it is dangerous, but I will try.正:Although it is dangerous, I will try. / It is dangerous, but I will try.不能将汉语的“虽然……但是……”直译为(al)though…but…,这是因为(al)though 为从属连词,用于引导让步状语从句;而but在表示“但是”时,它是并列连词,用以连接两个句子使之成为并列句。

由于在同一句中既用了从属连词(al)though,又用了并列连词but,使得句子一半像复合句,一半像并列句,从而导致错误。

正确的做法是,任意去掉(al)though 和but 中的一个,使之要么成为复合句,要么成为并列句。

易错点3 时间、条件状语从句中引导词的误用一、时间状语从句的用法归纳1. 引导时间状语从句的从属连词很多,常见的有before, after, when, while, as, since, till, until, as soon as 等。

2. 表示“当…时候”的while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用when;当表示“一边……一边……”或“随着”时,只能用as。

另外,用于此义的as 所引导的时间状语从句谓语只能是动作动词,不能是状态动词。

3. until 在肯定句中通常只连用延续性动词,表示相应动作结束的时间;在否定句中通常连用非延续性动词,表示相应动作开始的时间,意为“直到……才……”。

如:☞If you must go, at least wait till the rain stops. 如果你坚持要走, 至少也要等雨停了再走。

☞The letter passed from one to another until everyone had read it.那封信逐一传阅,直到每个人都看过为止。

4. 表示“一…就”除用as soon as 外,还可用the minute, the second, the instant, immediately, directly, instantly,no sooner…than, hardly…when 等。

如:☞I came immediately you called. 你一来电话我就来了。

☞Hardly had I opened the door when he told me. 我刚开开门,他就告诉了我。

☞The moment I have finished I'll give you a call. 我一干完就给你打电话。
