并列连词and_or_but_so用法_全面.doc

并列连词and，or，but，so用法英语中，连词是连接单词、短语或者句子的一种虚词，在句中不单独做任何成分。按照性质，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。并列连词可以用来表示并列关系、转折关系、选择关系或因果关系等。1.and的用法 并列连词and意为“和，又”，表示并列关系，常用来连接表示对等成分的单词、短语或者句子，表示意思的顺延或增补。例如：（1）Our Maths teacher is kind and helpful.我们数学老师和蔼可亲而且乐于帮助我们。(连接连个形容词）（2）I went to the supermarket and bought some vegetables this morning.今天早上我去超市买了一些蔬菜。（连接两个动词短语，表示意思的顺延，动作的先后发生）（3）Her uncle gave her a new bike as her birthday present and she liked it very much.她叔叔给了他一辆新自行车作为生日礼物，她非常喜欢。（连接连个简单句，表示意思的顺延，并列句） and用作并列连词有多重含义，除了表示并列关系外，还可以表示目的（and之后）和条件（and之前）等关系。例如：（4）Come and see my family.来见见我家人。（see表示目的）（5）Be careful,and you will make fewer mistakes.如果仔细，你犯的错误就少）（Be careful表示条件）2.but的用法 并列连词but意为“但是”，表示转折关系，所连接的成分意思相反或相对。例如：（1）Our school is small but beatiful.我们学校虽然小但很漂亮。（连接两个形容词，意思相对）（2）The car is very old but it runs very fast.虽然小汽车旧了，但跑得很快。3.or的用法 并列连词or意为“或者”，表示选择关系。例如：（1）Which do you like better ,juice or Coke?果汁和可乐，你更喜欢哪个？（连接两个名词）（2）Do you often go to school on foot or by bike?你经常步行去上学还是骑自行车去上学？（连接连个介词短语）（3）You can stay here, or you can leave.你可以待在这里，也可以离开。（连接两个简单句） 另外，在否定句中否定并列成分时，用or，而不用and。例如：（4）I cant speak English or French.我不会将英语和法语。（不能使用and） 英语中，“祈使句+or+简单句”结构，也是一种常用句型。句型中，or意为“否则”，祈使句相当于一个条件，可以和以“if”引导的条件状语从句进行转换。例如：（5）Put on your coat，or you will catch a cold.穿上你的上衣，否则你会感冒的。 =If you dont put on your coat,you will catch a cold.（转换成以“if ”引导的条件状语从句时，要去掉并列连词or）4.so的用法 并列连词so表示“因此、所以”之意，常用来连接两个简单句，这两个简单句有意思上的因果关系。例如：（1）The rain began to fall,so we went home.天开始下雨了，所以我们就回家了。（2）Everyone in the town knew him ,so we had no trouble finding hishouse.镇上谁都认识他，因此他们毫不费力就找到了他的家。so和从属连词because（因为）不能一起连用。也就是说，使用了并列连词）。就不用because(从属连词）；使用了because，就不用so。例如：他病了，没去上学。（3）He was ill,so he didnt go to school (本句是一个由并列连词so连接的并列句）（4）He didnt go to school because he was ill.（本句是一个由从属连词because引导的主从复合句） 并列句and,but,or练习题一：选择1.
