句子结构及成分.docx

1、句子结构及成分句子结构及成分一. 陈述句, 疑问句, 祈使句, 感叹句句子按用途可分四种：1）陈述句（肯定、否定）：He is six years old. She didnt hear of you before.2）疑问句（一般、特殊、选择、反意）：Do they like skating? How old is he?Is he six or seven years old?Mary can swim, cant she?3）祈使句：表示命令或者请求. 又叫无主句，主语通常为you,省略.Be careful, boys. Dont talk in class4）感叹句：how 后面加上

2、的是形容词副词.what后面加上的是名词.How clever the boy is! What a clever boy he is!二. 简单句、并列句和复合句句子按结构可分为简单句、并列句和复合句。1）简单句：只有一个主语（或并列主语）和一个谓语（或并列谓语）。e.g. He often reads English in the morning.Tom and Mike are American boys.She likes drawing and often draws pictures for the wall newspapers.（划线部分为并列谓语 ，只有一个主语，仍为简单句。

3、）2) 并列句：由并列连词（and, but, or等）或分号（；）把两个或两个以上的简单句连在一起构成。要注意哟,逗号是不可以连接句子的,这一点和汉语不同.e.g. You help him and he helps you.The future is bright; the road is tortuous. 前途是光明的，道路是曲折的。1、表示连接两个同等概念，常用and, not onlybut also, neithernor, then等连接。e.g. The teachers name is Smith, and the students name is John.2、表示选择，

4、常用的连词有or, eitheror, otherwise等。e.g. Hurry up, or youll miss the train.3、表示转折，常用的连词有but, still, however, yet, while, when等。e.g. He was a little man with thick glasses, but he had a strange way of making his classes lively and interesting.4、表示因果关系，常用的连词有so, for, therefore等。e.g. August is the time of t

5、he year for rive harvest, so every day I work from dawn until dark.3）复合句：复合句含有两个或两个以上主谓结构，其中一个主谓结构作另一个的成分。（而并列句的两个主谓结构间是并列关系， 而不是从属关系）。复合句包含：名词性从句（主语从句、宾语从句、表语从句和同位语从句）、定语从句和状语从句等。当简单句的一个成分从词或词组变为句子时，整个句子就成为复合句了。1. It is wrong. （只有一个主谓结构，是简单句） 2. What he said is wrong.（what he said,是一个主谓结构，he为主语，sai

6、d为谓语，what是宾语。What he said is wrong. 是另外一个主谓结构。What he said作主语，is wrong系表结构作谓语。因此，本句是复合句。What he said是名词性从句作主语）。3. The boy over there is my brother. （只有一个主谓结构，是简单句）4. The boy who is wearing a hat is my brother.（The boy is my brother.是一个主谓结构 who is wearing a hat也是一个主谓结构，作了前一个主谓结构中主语the boy的定语。因此本句是复合句

7、。）5. I was doing my homework at six. （只有一个主谓结构，是简单句）6. I was doing my homework when he came in.（I was doing my homework是一个主谓结构，he came in也是一个主谓结构。后面一个主谓结构作前一个的时间状语。因此是复合句。练习：判断下列句子是简单句、并列句还是复合句：1. We often study Chinese history on Friday afternoon.2. The boy who offered me his seat is called Tom.3.

8、There is a chair in this room, isnt there?4. My brother and I go to school at half past seven in the morning and come back home at seven in the evening.5. He is in Class One and I am in Class Two.6. He was fond of drawing when he was yet a child.7. Neither has he changed his mind, nor will he do so.

9、8. What he said at the meeting is very important, isnt it?9. The farmer is showing the boy how to plant a tree.10. Both Tom and Jack enjoy country music.11. Right now it is the summer vacation and Im helping my Dad on the farm.12. It is the time of year for the rice harvest, so every day I work from

10、 dawn until dark.13. Sometimes we go on working after dark by the lights of our tractors.14. We grow rice in the south of the States, but in the north where it is colder they grow wheat 15. Although the farm is large, my Dad has only two men working for him.考点： 两个主谓结构时，要用连接词，变为并列句或复合句一个句子如果出现两个主谓结构，

11、那它就不是简单句了，要么是并列句，要么是复合句。是并列句时要有and, so, but,等并列连词或用分号。是复合句时也要有连接词。总之，只用逗号而不用连接词简单的把两个主谓结构连接到一起的句子是错误的。如：I like English, my English is very good.I like English and my English is very good.As I like English, my English is very good. I have a house, its windows are very big. I have a house and its wind

12、ows are very big.

13、e playing football, they are from Class One.(6) Yesterday I helped an old man ,he had lost his way. (7) That is the teacher, he teaches us physics. 三. 句子成分现代汉语里一般的句子成分有六种，即主语、谓语、宾语、定语、状语和补语。英语的基本成分有七种：除 主语（subject）、谓语（predicate）、宾语（object）、定语（attribute）、状语(adverbial) 和补语（complement）之外还有 表语（predicati
