七年级英语句子成分

1、

英语句子与汉语句子一样,都是由单词按照一定的规则所组成的。不同的词类在句中所起的作用是不同的。因此,只有搞清不同词类在句中可充当哪些成分,才能正确分析、理解句子的含义,并能准确地遣词造句,逐渐达到流利地说出地道的英语。

【问】什么是句子成分?英语句子包含哪些成分?

【答】组成句子的各个部分叫做句子成分。它包括:主语、谓语、宾语、定语、状语、表语和宾语补足语等。 【问】各成分在句中的作用如何?分别由哪些词及短语充当?

1.主语:是句子要说明的人或事物,是句子的主体,一般由名词、代词、数词、不定式或动名词等充当。如:

? The car is running fast. / The girl can sing many English songs.(名词) ? We are students. / This is my pen . Yours is on the desk.(代词) ? One of my classmates is from Shanghai. / Two and three is finve.(数词) ? The blind need more help.(名词化的形容词) ? It's bad manners to spit in public. (不定式) ? Eating too much is bad for your health.(动名词)

? 【注意】若不定式短语作主语常用it作形式主语,而把真正的主语(不定式短语)放在句后。

.2.谓语:说明主语的动作或状态,也是句子的主体部分,一般由动词充当。动词分为实义动词、连系动词、情态动词和助动词。实义动词单独作谓语,连系动词与表语一起构成谓语,情态动词与省略to的不定式构成合成谓语,助动词与动词原形共同构成谓语部分。如:

? 由单一动词作谓语:We are Chinese. / He has an English- Chinese dictionary. ? 情态动词加主要动词:We can play the piano. / You must see the doctor. ? 助动词加主要动词构成谓语:She is talking with her sister. ? 【注意】谓语与主语在人称与数方面要相互照应。

3.表语:用于说明主语的身份、特征或感受,一般由名词、数词、形容词、分词等充当。常用的连系动词有:be,look,get,sound(听起来),feel,become, smell,turn,taste(尝起来)等。如:

? They are workers.(名词) ? Two and three is five.(数词) ? The story is very interesting.(形容词) ? M y job(工作)is teaching English.(动名词) ? She is at home.(介词短语) ? I feel terrible.(形容词)

? The dish tastes delicious.(形容词) ? He is here (副词)

? It’s getting dark. / He got very angry.

? 4, 宾语:是及物动词所涉及的对象,是动作的对象或承受者。一般由名词、代词、不定式及动名词等充当。

如:

? He is doing his homework. / I saw a plane in the sky just now. (名词) ? They did nothing this morning.

? I want three./ Please pass me the first. (数词) ? She wants to go home.(不定式) ? We enjoy playing football.(动名词)

? 【注意】①有的动词可接双宾语,间接宾语指人,直接宾语指物。这类动词常见的有:give,buy, tell等。

如:

? He bought me a book yesterday

? Xiao Liu bought a dictionary for Tom.(直宾+间宾)

? ②有的动词常用不定式作宾语,而不能用动名词。这类动词有:want,wish, hope等。如: ? I hope to see you again.

2

? ③有的动词一般只用动名词作宾语,而不用不定式。这类动词有:enjoy,practise等。如: ? He practises speaking English every day. ? I enjoy reading story books

? ④有的动词后接不定式与动名词含义不同。

? a)stop to do(不定式为状语)表示“停下原来的事,去做另一件事”,stop doing表示“停止做某事”。如: ? I stopped to talk with him.(我停下来与他谈话。)

? The students stopped talking when the teacher came in.(老师进来时学生们停止谈话。

? 注意:英语中带有宾语的谓语动词叫及物动词,不带宾语的叫不及物动词。及物动词后必须跟上宾语意义才

完整,不及物动词本身意义已完整,后面不跟宾语。 ? You may use my pen. / Do you like fish? ( 及物) ? Dick swims very well. / The sun rises in the east. (不及物) ? 不及物动词可加介词再加宾语 ? We are listening to the music. ? They are talking to each other.

既可以作及物动词又可以作不及物动词的词: ? My mother teaches in this school. / She teaches English. ? We are studying. / We study English.

? We began our lesson at nine. / The lecture began at nine. 5. 直接宾语与间接宾语。

? 有些及物动词可带有两个宾语,其中一个指物(直接宾语),另一个指人(间接宾语)。我们称为双宾语。? 动词+间接宾语(人)+直接宾语(物)

He bought me a pen.

6. 定语:用于修饰名词或代词,一般由形容词、名词、数词、不定式等充当。如:

? What a beautiful kite it is!/ They have a clever son.(形容词) ? She is a math teacher..(名词)

? There are two students in the classroom.(数词) ? This song is vey boring. (代词)

? Do you know the young man over there? (副词) ? We have something to do tomorrow.(不定式) ? The man in blue is my brother.(介词短语)
