Using both . and ., not only . but (also) ., either . or . and neither . nor,连 词 (Conjunction),一、连词定义: 用来连接词、短语或句子的词。 e.g. I study English and Chinese. Does he work at school or in the hospital? I get up early, but my brother gets up late.

2、,二、连词分类： 并列连词 从属连词,连词：and, but, or, so, for,连词词组: eitheror, neithernor, not onlybut also, bothand, (as well as),that, whether, if, unless, while / when, until, because, so that, sothat, though/ although, even if, asas 等,and的用法,1. and用来连接两个词性相同的词、短语或句子，表示并列关系。如： English and Chinese are different lang

3、uages.,and的用法,2. 如果连接两个含有相同的主语的句子或两个含有相同的主语和谓语的句子，and后可以省去相同的部分。如： We saw the tower and (we) liked it very much. He felt cold and (he felt) hungry.,and的用法,3. “祈使句+and+简单句”。 其中祈使句表示一个条件，并列连词and引导的简单句则表示一个较好的结果，谓语常用一般将来时。 该结构可转化为if引导的条件状语从句。如： Use your head, and you will find a way. = If you use your

4、head, you will find a way.,1）改错： They sat down and talk about something. They started to dance and sang. I saw two men sitting behind and ate there.,and (“和，并且”),eating,sing,talked,“and” 连接平行结构。,考点一：,but的用法,1. but的意思是“但是，然而，却”， 可用来连接两个有转折关系的词、短语或句子。如： He likes singing, but his sister likes dancing.,

5、but的用法,2. 如果连接两个含有相同的主语的句子或两个含有相同的主语和谓语的句子，but后可以省去相同的部分。如： The park was small but (the park was) beautiful.,表转折的连词but 和however： e.g. (他努力工作，但以失败告终。) He worked hard, _ he failed at last. He worked hard. _, he failed at last. 区别: but 后没有逗号，直接连接分句； however 后有逗号相隔，可放句末。,but,However,考点二 ：,*although/ tho

6、ugh 和but这两个关联词不能同用。,考点三 ：,(1) Although he is over sixty, but he works as hard as others. (F) 改为：Although he is over sixty, he works as hard as others. 或 He is over sixty, but he works as hard as others.,or的用法,1. or的意思是“或者”，表示选择关系。如： Are you coming or not? 你来还是不来？,or的用法,2. “祈使句+or+简单句”。 相当于otherwise祈

7、使句表示一个条件，连词or后的简单句则表示一个不愉快或不理想的结果。 该结构可转化为if引导的条件状语从句 （从句用否定形式，主句用一般将来时）。 如： Hurry up, or youll be late. = If you dont hurry up, youll be late.,or的用法,3. 在否定句中并列成分通常用or连接，而不用and I cannot speak Japanese or French.,（1）肯定句中用“and” 表“和”； （2）否定句中用“or”表“和” 。,1）翻译： 我喜欢英语和数学。 我不喜欢英语和数学。,I like English _ math.

8、,I dont like English _ math.,and,or,考点四：, and 和or,= Study hard, _ your math will be worse.,2 ）用 “and” 或“or” 填空： Study hard, _ your math will be better.,and,or,“and”意为“这样，那么”； “or” 意为 “否则” 。,or的用法,4. or连接两个主语时，谓语动词的单复数形式与or后面的主语表示一致，即遵循“就近原则”。如： James or Helen is going to tell us a story.,so的用法,1. so

9、意思是“因此，所以”，表示因果关系或结果。如： My teacher asked me to go, so I went.,so的用法,2. so不能与because同时出现在一个句子中。因为because是从属连词，而so是并列连词， 用来连接并列句。如： Mr Li was ill, so Mr Wang took his class instead.,(2) Because John was ill, so I took him to the doctor.,此句错误。 改正：John was ill, so I took him to the doctor. 或：Because Joh

10、n was ill , I took him to the doctor.,because 和 so 等关联词都不能同时使用。,考点五 ：,(F),1. Which is bigger, the sun _ the moon? 2. It was hard work, _ they really enjoyed it. 3.
