高中英语句子成分和句子种类

句子成分和句子种类详解
句子成分和结构是英语的基础，是理解和表达英语的关键。

英语中许多词类都对句子成分和结构有影响。

英语中的句子是由词或短语组成的，这些词或短语在句子中起一定的作用，叫做句子成分。

英语的篇章是由句子构成的，不同的内容需要不同类型的句式结构，这些句式结构又构成英语中不同的句子类型。

学习英语句法的基础是了解句子成分、句子的基本结构和句子种类。

I 句子成分
组成句子的各个部分叫做句子成分。

II 句子种类
英语句子按照使用目的和交际功能分为陈述句、疑问句、祈使句和感叹句。

1. 陈述句：陈述句用来叙述一件事情或表明说话人的看法、态度等，句末用“.”，一般读
作降调。

包括肯定陈述句和否定陈述句。

陈述句的语序一般为“主语部分+谓
语部分”。

1）陈述句的肯定形式：正常语序：He has answered my question clearly.
他已经清楚地回答了我的问题。

倒装语序：In front of our village runs a clear river.
在我们村庄前流淌着一条清澈的小河。

2）陈述句的否定形式：
（1）如果句子的谓语为be动词、助动词或情态动词等，其否定形式是在这些动词之后加not。

I am not good at Chinese.
我汉语不好。

She cannot play the piano.
她不会弹钢琴。

（2）如果句子的谓语是实义动词，在谓语动词前要用don't, doesn't, didn't的形式。

他们不知道我的地址和电话号码。

We don't go to school on Sundays.
我们星期天不上课。

She doesn't like coffee.

（3）其他否定词（如no, never, seldom, hardly, nobody等）也可构成否定式。

She seldom writes home.
她很少给家里写信。

注意：含有否定词缀（如由un-, im-, in-, dis-, -less等）构成的词，像dislike, unfortunate, impatient, impossible, unnecessary等，在句中表示否定意
义，但不看作否定句。

通常来说，像scarcely, seldom, hardly, few, little, almost not/no/never
等词表示的意思为半否定意义。

（4）双重否定
双重否定即两个表示否定意义的词连用的情况。

双重否定实际上是表示肯定，是一种强调用法。

常见的有：no/not/never...+without..., can
not/ never... too...to do..., no/ not/ never... + 表示否定意义的动词或短语。

Nothing is changeless.
万物都在变化中。

Man can't live without water or air.
没有水喝空气人类就无法生存。

（5）部分否定
总括词all, both, everyone, everything, everywhere, many, always等与not或never连用表示部分否定。

如果要表示完全否定，则用相应的否定词none, no
one, neither, nothing, nowhere, never等。

他并非总是上课迟到。

并非这儿所有的书都有用。

（6）否定前置
当主语为第一人称，谓语动词是think, believe, suppose, imagine, expect, feel 等时，说话者要委婉提出看法时，其宾语从句中的否定词往往转移到主句中。

I don't expect Tom has won the first prize.
我没有料到汤姆获得了一等奖。

We don't believe you have read that book, have you?
我们相信你没有看过那本书，对吗？
注意：英语中有些特殊句式，如疑问或感叹句式可以表示否定意义。

God only knows! (= No one knows. ) 天才晓得。

有些句子形式上为否定，但意义上却是肯定。

You can't be careful enough. 你越小心越好。

2.疑问句：疑问句用来提出问题，句末用问号“？”。

常见得疑问句有五种：
1）一般疑问句：用yes, no来回答的疑问句叫做一般疑问句，但在口语中有时也
用yes, no之外的词回答。

口语中若无特殊含义，句末用声调。

（1）用yes, no回答的一般疑问句
－Are your parents doctors? 你父母都是医生吗？
－Yes, they both are. 是的，他们都是。

（2）用yes, no之外的词回答的一般疑问句
一般疑问句也可用其他表示肯定或否定的词回答，如

at all, never, sorry, not yet, I'm afraid not等。

－Would you mind my joining your talk?

感谢，再讲明原因。

schedule is full that day. / I wish I could, but you
see I have a friend to visit.
你真是太好了，不过那天我的计划都满了。

/
我想来，不过我要去看望一个朋友。

（2）在回答带有否定词的一般疑问句时，答语中务必保
持“yes + 肯定句”“no + 否定句”的一致，同时
还要注意yes译成“不”，no译成“是”。

－Haven't you been to England?
你没到过英格兰吗？
－No, I haven't. / Yes, I have.
是的，没去过。

/ 不，我去过。

2）特殊疑问句：就句中某一部分进行提问的疑问句叫做特殊疑问句。

when, why, how等。

特殊疑问句末一般用降调。

疑问句。

如果你想外出吃饭，吃中餐怎么样？
How come you were late again?

因，表示惊讶。

3）选择疑问句：选择疑问句是说话者对问题提出两个或两个以上的答案，供
对方进行选择。

选择疑问句的前一部分用升调，后一部分用
降调。

这种疑问句有两种形式：一种以一般疑问句为基础，另
一种以特殊疑问句为基础。

or连接的两个并列成分可以是状
语、宾语、表语、谓语或两个句子等。

Shall we go home or stay here for the night?
我们今晚回家呢还是呆在这里？
How shall we go to the park, by bus or by taxi?

我们什么时候会和，六点还是七点？
－(We shall meet) At six.

你难道不知道你又错了吗？

5）反意疑问句：反意疑问句时附加在陈述句后的简单问句（又称附加问句），它征询对前面陈述内容的意见是肯定还是否定，或者希望证实陈述内
容。

反意疑问句分为形式上的反意疑问句合内容上的反意疑问句两类。

形式上的反意疑问句：要求与前面陈述句的主谓部分保持一致；
内容上的反意疑问句：要依据前面陈述内容或说话人的语气强调
中心而定。

其答语要根据内容的需要，要么
肯定要么否定。

（反意疑问句多用于证实一种情况或表达一种感情色彩）
结构为：“肯定，+ 否定？”或“否定，+ 肯定？”

在句首加do。

You be quiet for a moment.
你安静一会儿。
