1.句子的類型(Types of Sentences)

英語句子按結(jié)構(gòu)分為：簡單句、并列句和復合句等三種類型。

(1)簡單句(The Simple Sentence)

由一個主語(或并列主語)和一個謂語(或并列謂語)構(gòu)成的句子叫作簡單句。例如:

I usually get up at six in the morning on weekdays.

在工作日，我一般在早上六點鐘起床。

My sister and I didnt go skating last week.

上周，我和妹妹沒有去滑冰。

Are you going to study and work in London?

你要去倫敦學習和工作嗎？

(2)并列句(The Compound Sentence)

由并列連詞(如and, but, or, so, yet)把兩個或兩個以上的簡單句連在一起而構(gòu)成的句子叫作并列句。例如:

She turned off the light and went out. 她關(guān)了燈，出去了。

Mona was ill, so we took her to the hospital.

莫娜病了，因此我們送她去了醫(yī)院。

I like Spanish, but I need help.

我喜歡西班牙語，可是我需要人來幫我。

You can draw a good horse in five minutes, yet you kept me waiting for a year. 你能在五分鐘內(nèi)畫好一匹馬，卻讓我等了你一年。

(3)復合句(The Complex Sentence)

由一個主句和一個或一個以上的從句構(gòu)成的句子叫作復合句。例如:

Ill tell him as soon as I see him. (狀語從句)

我一看見他就告訴他。

She didnt come to the party because she was busy. (狀語從句)

她因為很忙，所以沒來參加聚會。

Hell go to see you if he has time. (狀語從句)

他如果有空，會去看你的。

I dont think you can miss it. (賓語從句)

我想你不會看不見的。

The problem is that he wont return on time. (表語從句)

問題是他不能按時回來。

What surprised us most is a strange cup with three legs. (主語從句)

最使我們感到吃驚的是一個有三只腳的杯子。

The time Yang Lei spent as a volunteer was the best year of his life. (定語從句)

楊磊作為一名志愿者那段時光是他一生當中最好的時間。

延伸 含時間狀語從句的復合句，既可以將狀語從句放在主句之后(念降調(diào))也可以將狀語從句置于主句之前(念升調(diào))，此時，從句和主句間加逗號。例如:

We were talking and laughing when the teacher came in.

(=When the teacher came in, we were talking and laughing.)

老師進來時，我們正在說笑。

應(yīng)用 指出下列句子中的錯誤，并改正。

①Mr Li with his children have fun in the park.

②Because she was ill, so she didnt come to school.

③Come to my house if you will have time.

④The man asked how we thought of his car.

⑤Sorry, Ive no pen to write now.

⑥The car hit the tree and slow down.

解答 ①have→has 主語是Mr Li。

②去掉Because或者sobecause與so不能同時用于一個句子中。

③去掉will在條件狀語從句中，將來的動作常用一般現(xiàn)在時表示。

④how→what 句型“what…think of”意思是“覺得……怎樣”。

⑤write→write with 動詞不定式to write with與被修飾詞pen有邏輯上的動賓關(guān)系。

⑥slow→slowed 前后時態(tài)一致，句中hit是過去式。

2.狀語從句(The Adverbial Clause)

在復合句中修飾主句的動詞、形容詞或副詞等的從句叫作狀語從句。狀語從句根據(jù)它表達意思的不同可分為時間、地點、原因、目的、結(jié)果、讓步、比較(或方式)和條件等狀語從句。

(1)時間狀語從句

由when, before, after, while, until, as, as soon as等連詞引導。

I went to bed after the TV play was over. 電視劇播完后我就睡了。

She has been here since she came to the school.

自從她上學，她就一直住在這兒。

As I was waiting, I suddenly heard a voice from above.

我正等的時候，突然從上面?zhèn)鱽砹寺曇簟?/p>

Go straight until you come to a crossing. 筆直走，一直走到十字路口。

(2)條件狀語從句

由if, unless等連詞引導。

Ill go with you to the movies this afternoon if Im free.

今天下午我如果有空，我將與你一起去看電影。

Youll be late unless you hurry. 如果不趕快，你會遲到。

(3)原因狀語從句

由because等連詞引導。

The store wont be open today because theyre repairing.

商店今天不開業(yè)，因為在維修。

(4)目的狀語從句

由so that, in order that等連詞引導。

Speak loudly so that all of us can hear clearly.

大點聲講，以便我們大家都能聽清楚。

(5)讓步狀語從句

由though, although等連詞引導。

They were still working in the street though it was so hot.

天雖然這么熱，但是他們?nèi)匀辉诖蠼稚瞎ぷ鳌?/p>

警示 英語中表示“雖然……但是……”不同于漢語，要么用連詞though或although,要么用連詞but。例如:

Though (Although) Lisa is young, she knows much Chinese.

(=Lisa is young, but she knows much Chinese.)

麗莎雖然年輕，但是知道不少漢語。

類似地，because也不與so同時用于一個句子中。

(6)比較(或方式)狀語從句

由than, as…as, not as(so)…as等引導。

Our earth is bigger than the moon (is). 我們住的地球比月球大。

This story is as interesting as that one (is).

這個故事與那個故事一樣有趣。

India is not so developed as the U.S.A. 印度不如美國發(fā)達。

應(yīng)用 選擇填空。

A. since B. when C. while D. until

②____ you dont find the library book, youll have to pay for it.

A. If B. Unless C. After D. While

⑤At that time the train ran slower than the carriage ____.

A. ran B. was C. did D. could

⑥Please be quick, ____ well miss the early bus.

A. and B. but C. so D. or

解答 ①B while引導的從句中不能用非持續(xù)性動詞。

②A 表示假設(shè)關(guān)系。

③B A和D不正確，C項前后時態(tài)不一致，只能是B。

④D so…as只用于否定句，as…as可用于所有句型。

⑤C 此空要么不填，要么用did代替前文的動詞ran。

⑥D(zhuǎn) or表示“否則”的意思。
