小學(xué)英語語法:句子的種類

13. 句子的種類

(一)按使用目的可分為陳述句、疑問句、祈使句和感嘆句。

1) 陳述句(Declarative Sentences)：說明一個事實或陳述一種看法。

Light travels faster than sound.　光比聲速度快。　　(說明事實)

The film is rather boring.　這部電影很乏味。

(說明看法)

2) 疑問句(Interrogative Sentences)：提出問題。有以下四種：

a.　一般疑問句(General Questions)：

Can you finish the work in time?

你能按時完成工作嗎?

b.　特殊疑問句(W Questions; H Questions)：

Where do you live?　你住那兒?

How do you know that? 你怎么知道那件事?

c.　選擇疑問句(Alternative Questions)：

Do you want tea or coffee?

你是要茶還是要咖啡?

d.　反意疑問句(Tag-Questions)：

He doesn't know her, does he?

他不認(rèn)識她，對不對?

3) 祈使句(Imperative Sentences)：提出請求，建議或發(fā)出命令，例如：

Sit down, please.　請坐。

Don't be nervous!　別緊張!

4) 感嘆句(Exclamatory Sentences)：表示說話人驚奇、喜悅、憤怒等情緒，例如：

What good news it is!　多好的消息啊!

(二)句子按其結(jié)構(gòu)可以分為以下三類：

1) 簡單句(Simple Sentences)：只包含一個主謂結(jié)構(gòu)句子叫簡單句，例如：

She is fond of collecting stamps.　 她喜歡集郵。

(主)　 (謂)

2) 并列句(Compound Sentences)：包含兩個或兩個以上主謂結(jié)構(gòu)的句子叫并列句，句與句之間通常用并列連詞或分號來連接，例如：

The food was good, but he had little appetite.

(主)　　 (謂)　　　　　 (主)(謂)

食物很精美，但他卻沒什么胃口。

3) 復(fù)合句(Complex Sentences)：包含一個主句從句和一個或幾個從句的句子叫復(fù)合句，從句由從屬連詞引導(dǎo)，例如：

The film had begun when we got to the cinema.

主句　　　　　　 從句

我們到達(dá)電影院的時候，電影已經(jīng)開演了。

(三)基本句型(Basic Sentence Patterns)：英語中千變?nèi)f化的句子歸根結(jié)底都是由以下五種基本句型組合、擴展、變化而來的：

1)主 + 動(SV)例如：

I work.　我工作。

2)主 + 動 + 表(SVP)例如：

John is busy.　約翰忙。

3)主 + 動 + 賓(SVO)例如：

She studies English.　她學(xué)英語。

4)主 + 動 + 賓 + 補(SVOC)例如：

Time would prove me right. 時間會證明我是對的。

5)主 + 動 + 間賓 + 直賓(SVOiOd)例如：

My mother made me a new dress.　我母親給我做了一件新衣裳。

13.1 祈使句結(jié)構(gòu)

祈使句用以表達(dá)命令，要求，請求，勸告等。

1) 祈使句有兩種類型，一種是以動詞原形開頭，在動詞原形之前加do (但只限于省略第二人稱主語的句子)。

Take this seat.

Do be careful.

否定結(jié)構(gòu)：

Don't move.

Don't be late.

2) 第二種祈使句以let開頭。

Let 的反意疑問句

a. Let's 包括說話者

Let's have another try，shall we / shan't we?

= Shall we have another try?

b.　Let us 不包括說話者

Let us have another try，will you / won't you?

= Will you please let us have another try?

否定結(jié)構(gòu)：

Let's not talk of that matter.

Let us not talk of that matter.

13.2 感嘆句結(jié)構(gòu)

感嘆句通常有what, how引導(dǎo)，表示贊美、驚嘆、喜 悅、等感情。

what修飾名詞，how 修飾形容詞，副詞或動詞，感嘆句結(jié)構(gòu)主要有以下幾種：

掌握它的搭配，即掌握了感嘆句的重點。

How +形容詞+ a +名詞+　　　　　　　陳述語序

How+形容詞或副詞+　　　　　　　　　陳述語序

What +名詞+　　　　　　　　　　　　陳述語序

What+a+形容詞+名詞+　　　　　　　　陳述語序

What+ 形容詞+復(fù)數(shù)名詞+　　　　　　 陳述語序

What+ 形容詞+不可數(shù)名詞+　　　　　 陳述語序

How clever a boy he is!

How lovely the baby is!

What noise they are making!

What a clever boy he is!

What wonderful ideas (we have)!

What cold weather it is!

感嘆句的省略形式為：

What a clever boy (he is)!

典型例題

1)___ food you've cooked!

A. How a nice　　B. What a nice　　C. How nice　 D. What nice

答案D. 由于How 修飾形容詞，副詞;what修飾名詞。且food為不可數(shù)名詞，因此A，B 排除。C How + adj. 后面不能再加名詞，因此只有D正確，其句型為What + adj. +n. (不可數(shù))

2)___terrible weather we've been having these days!

A. What　 B. What a　　C. How　 D. How a

答案A. weather為不可數(shù)名詞，B，D排除。C為how + adj. 后面不應(yīng)有名詞。只有A，符合句型What +形容詞+不可數(shù)名詞。

3) --- _____ I had!

--- You really suffered a lot.

A. What a time　　B. What time　　 C. How a time　　 D. how time

答案A.　感嘆句分兩類：

1：What + n.+主謂部分

2：How + adj. / adv. / v.+主謂部分。本題屬第一種，但省略了bad，相對于 What a bad time I had! 這是個習(xí)慣用語。

13.3 強調(diào)句結(jié)構(gòu)

?？嫉膹娬{(diào)句結(jié)構(gòu)是it 引導(dǎo)的句子。

It is (was) 被強調(diào)部分+ that (who) + 句子其他部分。

此結(jié)構(gòu)強調(diào)的成分僅限于主語，賓語和狀語。

It is from the sun that we get light and heat.

It was not until I had read your letter that I understood the true state of affairs.

典型例題

1) It was last night ___ I see the comet.

A.　the time　B.　when　 C.　that　　D.　which

答案C. 強調(diào)句的結(jié)構(gòu)是： It +be +強調(diào)部分 + that (who) + 主謂句?！娬{(diào)句的連詞只有兩個，that和who。當(dāng)強調(diào)的部分是人，且為句子的主語時，才用 "who"，其余用that。

原句：　My father did the experiment in the lab yesterday evening.

強調(diào)主語： It was my father who did the experiment in the lab yesterday evening.

強調(diào)賓語： It was the experiment that my father did in the lab yesterday evening.

強調(diào)時間： It was yesterday evening that my father did the experiment in the lab. (注意不用when)

強調(diào)地點： It was in the lab that my father did the experiment yesterday evening.

2)It is ten years ___ Miss Green returned to Canada.

A. that　B. when　 C. since　 D. as

答案C. 考點是連詞用法。 本題易誤選為A. that. 其實本句不是強調(diào)句。若是，去掉It　 be… that還應(yīng)是一個完整的句子。而本句去掉 'It is…that'，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是強調(diào)句。

It is /was +時間+ since…　其中is<---> has been　 was <---> had been.

13.4 用助動詞進(jìn)行強調(diào)

強調(diào)句還有一種類型，就是用助動詞do (did，does) 強調(diào)謂語。

She does like this horse.　她的確喜歡這匹馬。

Please do take care of yourself. 千萬保重。
