中考英语语法连词.ppt

1、连词,连词是一种虚词, 在句中不单独充当句子成分，只起连接词与词、短语与短语以及句子与句子的作用。在汉语里，通常可以把两个或更多的句子连起来而不用连词，这在英语中一般是不行的，句子只要一超过两个，通常就要用连词连接。连词一般不重读，分为并列连词和从属连词。并列连词引出并列句，从属连词引出主从复合句。,考点一 并列连词 并列连词是用来连接语法地位相同的单词、短语以及句子的连词。并列连词主要分为表示并列关系、转折关系、因果关系及选择关系的并列连词。,【温馨提示】 1. 两对“冤家对头”不能同时出现在一个句子中: although/ though与but；because与so。 2. and和or的

4、oull get good grades. =If you work hard, youll get good grades. 努力学习，你会取得好成绩。,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 couldnt leave the house. 他把鞋拿走了，我出不了门。 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
