用语as well 与as well as用法归纳

用语as well 与as well as用法归纳
用语as well 与as well as用法归纳

用语as well 与as well as用法归纳as well与as well as只有一词之差,但意义和用法却相差甚远。

一、as well 用法:

1、as well常用作状语,作“又;也”解,相当于too或also,常位于句末,无须用逗号与句子分开。如:

I am going to London and my sister is going as well(=going,too).我要到伦敦去,我妹妹也要去。

I not only play the guitar,I sing as well(=I also sing ). 我不但弹吉他,而且还演唱。

2、as well 在口语中也可用于句中,作“也好,也行”或“倒不如”解,用来缓和语气。如:

You may as well go. 你去也好。

The weather was so bad that we might(just)as well have stayed at home.

天气太坏了,早知道如此,倒不如呆在家里为好。

3、as well 可以直接用于just后,用作应答语(可视为It's just as well、的省略),作“幸亏,幸而;无妨;没关系”解。如:

—We were too late to see the film.我们去得太晚了,没有看上电影。

—Just as well、I hear it isn't very good. 不必遗憾,我听说电影也不怎么样。

二. as well as

一、分清本义与引申义

1.用于本义

as well as 用于本义,可视为as…as结构与well的自然搭配,其意为“与……一样好”,在否定句中可用not so well as代替 not as well as。如:

He speaks English as well as her. 他说英语说得跟她一样好。

She plays every bit as well as the men. 她打得一点不比男人们差。

He sings as well as, if not better than, Mary. 要是他唱歌不比玛丽唱得更好,但至少也是一样好。

2.用于引申义

用于引申义,表示“不但……而且”“既是……也是”“而且”“还”。如:

He grows flowers as well as vegetables. 他既种菜也种花。

She shares (in) my troubles as well as my joys. 她与我同甘共苦。

注:有时还可译为“除……之外,还”,与besides, in addition to的用法相似。如:

As well as learning to swim, he has been taking Spanish lessons this summer. 今年夏天,他除了学习游泳外,他还在上西班牙语课。

二、弄清强调重点

A as well as B这一结构强调的重点是A不是B,即 A as well as B=not only

B but also A,注意体会以下例句的译文:

She is clever as well as beautiful. 她不但漂亮,而且聪明。

He speaks Spanish as well as English and French. 他不仅会说英语和法语,而且会说西班牙语。

三、把握主谓一致

当 as well as 连接两个成分作主语时, 其后的谓语通常要与前面一个主语保持一致。如:

Tom as well as his parents is going to London. 汤姆和他的父母要去伦敦。

The captain, as well as the other players, was tired. 队长和其他队员都累了。

四、牢记后续动词的形式

as well as 后接动词到底是该用什么形式,这是一比较复杂的问题,归纳起来有以下几点值得注意:

1. as well as 通常被视为介词,所以后接动词时,一般用动名词形式。如:

He sings as well as playing the piano. 他不但会弹钢琴,而且会唱歌。

As well as breaking his leg, he hurt his arm. 他不但摔断了腿,而且还伤了胳膊。

She is a talented musician as well as being a photographer. 她不但是摄影师还是个天才的音乐家。

注:as well as 后接动词用动名词的情况主要见于主句谓语为简单时态(即一般现在时和一般过去时)的时候。

2.如果主句谓语为复合时态(即其中含有情态动词或助动词),则as well as 后的动词通常要与情态动词或助动词后的动词形式保持一致。如:

Students should pursue their own interests, as well as do their school work. 学生不仅应该做要好家庭作业,而且还要有自己的兴趣。

I have to feed the animals as well as look after the children. 我不但要照顾孩子们,而且还要喂动物

3.如果as well as 是连接两个不定式,则其后用不带to的不定式。如:

A museum should aim to entertain as well as educate. 博物馆不仅要有教育性还且还要有娱乐性。

We cannot expect her to do the homework as well as look after the children. 我们不能指望她既做作业又照看孩子。

4.当as well as 用于句首时,其后习惯上要接动名词。如:

As well as eating a seven-course meal, they drank three bottles of wine. 除吃了一顿有七道菜的饭之外,他们还喝了三瓶酒。

As well as walking, he likes fishing and shooting. 他除散步之外还喜欢钓鱼和打猎。

As well as visiting Niagara Falls, we spent a day in Toronto. 我们参观了Niagara 瀑布,而且学在多伦多玩了一天。

注:as well as 有时也被视为准并列连词,后接的动词可以与主句谓语动词形式一致(但这种情形远不如用后接动名词普遍)。如:

He publishes as well as prints his own books. 他不但印刷而且还出版自己的书。

高中英语 语法复习二十一 连词

语法复习二十一:连词 连词分为并列连词和从属连词两大类。并列连词是连接主语与主语,谓语与谓语,句子与句子,分词与分词的词,它要求前后两部分有相同的形式和语法作用;而从属连词一般连接主句与从句,从句形式有名词性从句,定语从句和状语从句等。 (一)并列连词: 并列连词可用来连接词与词,词组与词组,分句与分句。常用的并列连词有:and(和),as well as(既…又),both … and(不但…而且),not only … but also(不但…而且),not … but(不是…而是),neithe r … nor(既不…也不),either … or(不是…就是),or(或者),but (但是),yet(然而),for(因为),so(所以),while(而),when(这时)等。如:Both my brother and my sister are teachers./ His room is bright but mine is gloomy(暗沉沉的)./ He can not only repair radios but also fix them./ It is a glorious(光荣的)yet difficult task./ Strike while iron is hot. (二)从属连词 从属连词是指在复合句中引导从句的连结词。常见的从属连词有: 引导时间状语从句的:after, before, when, as, while, since, until, till, as soon as 引导原因状语从句的:because, since, as 引导让步状语从句的:although, though, no matter(无论), even if (though) 引导条件状语从句的:if, unless, once, so (as) long as 引导结果状语从句的:so … that …, such … that … 引导目的状语从句的:so that …, in order that … 引导比较状语从句的:as … as …, not so (as) … as …, … than … 引导方式状语从句的:as if … 引导主语,宾语或表语从句的连词主要有:that, whether, if三个。其中that 和whether 间或还可以引起同位从句和状语从句。 (三)某些用法比较特殊的从属连词用法区别 1、当while, when, as引导时间状语从句时的区别:①while引导的状语从句中动词必须是持续性。谓语动词多为进行时,或状态动词的一般时。while 的这些用法可用when代替,等于“at the time that”, “during the time that”。例如:Please keep quiet while (when) others are studying;② when除可指一段时间外,还可用来指一点时间,等于“at the time”,也就是说when引出的时间状语从句中的谓语动词可以是终止性的,也可以延续性的。因此主句和从句的谓语可以是一般时,进行时,或完成时。例如:When I went into the lab, the teacher was doing an experiment.(when不能换成while)He often makes mistakes when he is speaking English.(when可换成while)③as常可与when,while通用,但强调“一边、一边”。例如:
