分析句子結(jié)構(gòu)是對所學語法的綜合運用。對句子的結(jié)構(gòu)是否清楚、明白是能否正確解答問題的關(guān)鍵。因此學會如何分析句子對更深刻、準確地理解題意，提高解題能力至關(guān)重要。

所謂分析句子就是要剖析句子各個不同成分，并弄清楚他們彼此之間的關(guān)系。現(xiàn)對怎樣分析句子做一簡單介紹。

分析句子的步驟：

①先找出句子的謂語動詞，并考慮動詞的性質(zhì)，這是能否正確分析句子的關(guān)鍵。

②找出和謂語關(guān)系最密切的句子成分一主語。審查兩者之間的關(guān)系是否一致。

③確認動詞性質(zhì)后，進一步分析動詞與其他句子成分的關(guān)系。如與賓語、賓語補足語、表語、狀語以及與小品詞的關(guān)系等。

現(xiàn)做具體說明如下：

1.謂語動詞：謂語動詞是句子的核心。任何時態(tài)、語態(tài)，語氣都是由謂語動詞表示出來。所以在分析句子時首先要分析謂語動詞。

動詞有及物動詞和不及物動詞。根據(jù)他們的功能，可以構(gòu)成下列幾種基本句型，

①主語+系動詞+表語(主系表結(jié)構(gòu))，如：

This lesson is very difficult.這課很難。

②主語+不及物動詞，如;

He has come.他已經(jīng)來了。

③主語+及物動詞+賓語(主謂賓結(jié)構(gòu))，如，

He reads English everyday. 他每天讀英語。

④主語+及物動詞+間接賓語+直接賓語或主語牛及物動詞+直接賓語+介詞(to或for等)+間接賓語，如:

His father bought him 9 new bike yesterday.

His father bought a new bike for him yesterday，

昨天他父親給他買了一輛新自行車。

⑤主語+及物動詞+賓語十賓語補語，如：

We made him our monitor.我們讓他當班長。

2。主謂關(guān)系：任何簡單的句子都有主語和謂語，在分析主謂關(guān)系是否一致時，可從三個方面考慮。即語法上的一致，語言內(nèi)容上的一致和就近一致。

①語法上的一致：指謂語動詞的形式要與主語的形式一致。主浯為單數(shù)形式，謂語動詞也采取單數(shù)形式;主語為復數(shù)形式，謂語動詞也采取復數(shù)形式。這個法則符合語法形式上一致的原則。

以單數(shù)名詞或代詞，動詞不定式短語，動名詞短浯或從句做主語時，謂語動詞一般用單數(shù)形式。以what引起的從句做主語時，在大多數(shù)情況下其后面的謂語動詞也用單數(shù)形式。如：

What we have seen is different[rom what we have heard.

(what從句作主語，動詞用單數(shù))

To answer correctly is more important than to finish quickly，

(不定式短語作主語)

A great deal of work has been done to improve the people's living standard.

(不可數(shù)名詞作主語)

用“and，，和“both … and”連接的并列主語，謂語動詞多用復數(shù)形式，但并列主語如果指同一人、同一事物或同一概念的時候，and后面的名詞沒有冠詞，謂語動詞用單數(shù)形式。如：

Both the man and his wife want to go to the cinema.

The poet and writer has come.

Bread and butter is daily food in the West.

主語是單數(shù)后面跟as well as，with，besides，along with，together with等，謂語動詞仍用單數(shù)，如：

The teacher as well as the students likes this novel.

My sister，together with Jane and James，is gone.

一些有復數(shù)的名詞，例如clothes.scissors，trousers，scales，spectacles等，作主語時，謂語動詞用復數(shù)形式，但如在成雙的東西的名詞前面有apairo{時，其謂語動詞用單數(shù)。如：

My trousers are being mended。

This pair of scissors belongs to me.

有些詞尾有“s”的學科名稱，做主語時，謂語動詞用單數(shù)形式。如：

Mathematics is taught here.

.

②語言內(nèi)容上的一致：主要指從意義上考慮主謂一致的問題。主語形式上為單數(shù)，但意義上為復數(shù)，謂語動詞要用復數(shù)形式;主語形式上是復數(shù)，但意義上為單數(shù)，謂語動詞用單數(shù)形式。

One hundred tons of water were used last week.(強調(diào)數(shù)量)

Ten minutes is enough.(強調(diào)整體)

News is travelling fast nowadays.

This glass works was built in 1985.

有復數(shù)意義的名詞，如：police，militia，people，cattle等作主語時，謂語動詞用復數(shù)形式。如：

The police are trying to catch the thief who has stolen a bike.

Cattle feed on grass.

有些集合名詞，如;family，group，crowd，class，audience，government，committee。說話人把它們所表示的人或事當做整體看時，作單數(shù)看待，謂語動詞用單數(shù)形式;說話者把它們表示的人或事物當做若干個體來看時，作復數(shù)看待，謂語動詞也用復數(shù)形式。如：

My family is large.

My family are anxious about his safety.

③就近一致：由并列連詞如：whether...or，not only...but also，either...or，neither...nor，or連接的并列主語，謂語動詞與其最近的主語保持一致。如：

Either his friends or his brother is wrong.

Either his brother or his friends are wrong.

Not only you but also he is wrong.

Not only he but also you are wrong.

3.動賓關(guān)系：在確認動詞性質(zhì)后，要注意審查其后面的賓語。要特別注意賓語應該用動詞不定式還是應該用動名詞;賓語補足語是應該帶to還是不應該帶to;動詞后帶的動名詞或動詞不定式的意義基本相同還是意義不同。

時態(tài)的一致：某些從句特別是賓語從句的謂語動詞的時態(tài)，常受主句謂語動詞的時態(tài)的影響，這種現(xiàn)象稱為時態(tài)的呼應或時態(tài)的一致。因而在分析復合句時要注意主句和從句的時態(tài)的一致性。

主句的謂語動詞是現(xiàn)在或?qū)頃r態(tài)時，從句的謂語動詞可以用任何需要的時態(tài)。

It is said that a new hospital is going to be put up there next year.(現(xiàn)在時后接將來時)

Do you know 他昨天為什么沒有來?

A.why he did not come yesterday

B.why he not come yesterday

C。why didn't he come yesterday

D.why did he not come yesterday

現(xiàn)在時后接過去時。答案A

I'll write to him when I arrive there.(主句將來時，從句現(xiàn)在時。)

主句的時態(tài)是過去時，從句的謂語動詞一般也用過去時。

①從句的動作與主句的動作同時發(fā)生時，從句謂語動詞用一般過去時或過去進行時。

He told me that his uncle...(fly)to Britain the next month.

(答案would fly)

She told me that her daughter was doing her homework.

②從句謂語動詞的動作先于主句謂語動詞的動作，從句用過去完成時，如：

She said she had seen the film before.

She said she had finished the work an hour before.

③從句的謂語動詞的動作發(fā)生在主句謂語動詞的動作之后，從句謂語動詞用過去將來時。如：

She said she would come again.

He told me he would join the army the next year.

但是如果從句有表示過去的具體時間狀語，謂語動詞發(fā)生的動作雖在主句的謂語動詞的動作之前，仍用一般過去時。如：

Johntold us hismotherdiedin 1967.

如果從句表示的是不受時間限制的真理或事實，即使主句的謂語動詞是過去時態(tài)，從句仍用一般現(xiàn)在時。如：

The teacher told the students water boils at 100C.

She said twice two is four.
