单元语法归纳与练习
1.在英语中,连词是连接单词、短语或句子的一种虚词,在句中不单独充
当任何成分。按照性质不同,连词可以分为并列连词和从属连词。由并
列连词连接的两个(或两个以上)简单句叫做并列句,由从属连词连接的
句子叫做主从复合句。并列连词可用来表示并列关系、转折关系、选
择关系或因果关系等。
连词——and,but,or,so
2.种类
英语中连词的用法讲解
表示并列关系 and意为“和、而且”,多用于肯定句。在否定句中,多用or表示“和”。(见例①和例②)
表示转折关系 but 意为“但是”。(见例③)
表示选择关系 or意为“或;否则”。(见例④)
表示因果关系 so意为“所以;因此;于是”。(见例⑤)
例句:
①Smile to the world,and the world will smile back to you.
对世界微笑,世界也会对你微笑。
②I have no brothers or sisters.
我没有兄弟姐妹。
③I want to buy a new iPad,but I don’t have enough money.
我想买一个新iPad,但我没有足够的钱。
④Which season do you like better,summer or winter

⑤The traffic was too heavy,so we were late.
交通太拥堵,所以我们迟到了。
3.常见的短语连词
both...and...这一连词的意思是“……和……都……,既……也……”,它可以连接句
中句子成分相同的词语,如果用它连接主语时,谓语动词要用复数形式。
Both Li Ping and her mother take exercise every morning.李萍和她妈妈每天早
晨都进行锻炼。
not only ...but also ...意为“不但……而且……”,可以连接句中句子成分相同的
部分,如果用它连接主语时,谓语动词的单复数应该和but also后面的主语保持一致。
Emma is not only beautiful but also kind.埃玛不但漂亮,而且人非常好。
either...or...的意思是“或者……或者……,不是……就是……”,它可以连接句中句
子成分相同的词语,在用它连接主语时,谓语动词的单复数应该和or后面的主语保持一致。
Either you or he is right.或者你是对的,或者他是对的。
neither...nor ...的意思是“既不……也不……”,它可以连接句中句子成分相同的词
语。由于它本身带有否定含义,所以谓语动词应该用肯定形式。用它连接主语时,谓语动
词的单复数要和nor后面的主语保持一致。
Neither his parents nor he has lunch at home.
他的父母和他都不在家里吃午饭。
温馨提示:
在汉语中“因为……所以”,“虽然……但是”可以连用,但是在英语中,because和so,(al)though和but不能同时在一个句子中出现,只能使用其中一个。
例如:He studies hard,so he makes great progress.
=Because he studies hard,he makes great progress.
因为他努力学习,所以取得了很大进步。

【易错提醒】
1.易错选B,受provide...for...意为“为……提供……”的影响。本题中
考查短语:provide sb.with sth.为某人提供某物,故选A。
2.易错选B,看到了提示词then“在那时”,错误地以为是一般过去时,但忽
视了since,“since+时间点”是现在完成时的标志,故选C。
3.易错选A。没理解Thanks=Thank you。题中宾语是the bus driver,若选
A,不符合逻辑。thanks to多亏,选C。
4.易错选A。只考虑了because“因为”,便想到了“所以”。但在英语中,
because和so不能同时出现在一个句子中。
5.易错选D。受主句中will的影响,错误地选择D项。但是在本题中,if引导
条件状语从句,主句用一般将来时,从句要用一般现在时,遵从“主将从
现”的时态规则。所以选B。
