as-well-as讲解.doc

一、as well as构成同级比较结构，意为“和一样好”。这时，第一个as是副词，第二个as是连词，引导一个状语从句，表示同级比较。 He speaks English as well as a native speaker.他讲的英语是和英语是母语的人一样好。 He can operate the machine as well as I do.他操作这台机器和我一样熟练。 二、as well as用作连词，连接两个并列的同等成分，其意义为“不但而且”，“既又”，这时相当于not only . but also .。它所连接的部分既可以是单词、短语，也可以是句子。值得注意的是，在A as well as B的结构里，语意的重点在A，不在B。翻译时要特别注意。 The girl is lively as well as healthy.（连接两个表语）这女孩既健康又漂亮。 He can speak Spanish as well as English.(连接两个宾语) 他不但会说英语，而且会讲西班牙语。 In China, as well as in Canada, the weather changes from season to season. (连接两个状语) 中国的天气和加拿大一样随季节的变化而变化。 The teacher as well as the students enjoys listening to English songs.（连接两个主语）老师和学生都爱听英语歌曲。三、as well as当作复杂介词，意思是“除了之外，还有”，后面通常接名词或动名词，相当于besides，apart from，in addition to。 Hiking is good exercise as well as fun. 徒步旅行除了有趣之外，还是很好的运动。 As well as eating seven-course meals, they drank three bottles of wine.他们除了吃了七道菜之外，还喝了三瓶酒。 四、在使用as well as时还应注意以下几点： 1.连接两个并列成分作主语时，句子的谓语动词应该与前面那个名词或代词的人称或数保持一致。 Mary as well as I has been to the Great Wall.我和玛丽去过长城。 His children as well as his wife were invited to the party.不但他太太，连他的孩子们也都被邀请参加了聚会。 2.连接动词时应注意以下几种情况： 如果as well as连接的是两个简单动词形式，它和第二个动词实际上起着插入语的作用，这时as well as后的动词在人称和数上应与主语保持一致。 They play the piano as well as sing.他们不但会唱歌，而且会弹琴。 He works, as well as sleeps, in the room. 他既在这房间里睡觉，又在这儿工作。 如果as well as前面的动词是复合时态，或由情态动词can，may，must等加动词构成时，as well as后面可省去助动词或情态动词。 The boy has learned to speak English as well as read some English books.这个男孩不仅读了一些英语书，而且学会了说英语。 She can / could sing as well as dance.她既会跳舞也会唱歌。 如果as well as前面是带to的动词不定式，其后的动词不定式省去to；当重复同一动词时，可用do代替。 You cant expect her to do the housework as well as look after the children.你不可能叫她既照看小孩又做家务。 He seemed to understand human nature as well as do science.他不但 如果谓语是一般现在时或一般过去时，as well as之后可与前面一致，也可用动名词形式。 She sings as well as playing the piano.她不但会弹钢琴，而且会唱歌。 The report was impersonal as well as being precise.这份报告不仅精细，而且不带个人色彩。 如果as well as前面的动词是分词，as well as后的动词也应用分词形式。 We are repairing the roof, as well as painting the walls. 我们既油漆墙壁，又修房顶。 3.用于否定结构中not位于as well as后时，两者都否定；not用于as well as前时，否定前者，肯定后者。试比较： I shall not see the film as well as he.他将去看电影，而我不去。 I, as well as he, shall not see the film.他不去看电影，我也不去。 4. as well as连接的人称代词，既可以是主格，也可以是宾格，但句意不同。 They have invited you as well as me. 他们邀请了我，也邀请了你。（you和me都作宾语） They have invited you as well as I. 他们和我一样都邀请了你。（they和I都作主语） 五、用法拓展 1. as well，是副词短语，意思是“也”，相当于too / also常位于句尾，与too位置相当，无须用逗号与句子分开。 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。 （注：专业文档是经验性极强的领域，无法思考和涵盖全面，素材和资料部分来自网络，供参考。可复制、编制，期待你的好评与关注）
