1.[考題] ____ are playing computer games.

A. All of boys B. The all boys C. All the boys D. Boys all

[要點]all 作形容詞時,意為“所有的,全部的”,指三者或三者以上的人或物,常用于定冠詞、物主代詞、基數(shù)詞或指示代詞this, that, these, those 等之前。例如:

all the young trees 所有的幼樹 all those students 所有的學生

[拓展] all 還可作副詞,意為“完全”,常位于系動詞、情態(tài)動詞或助動詞之后,行為動詞之前。例如:

They are all teachers. 他們都是教師。(系動詞之后)

They all went to work. 他們都上班去了。(行為動詞之前)

另外,all 也可作代詞,可指代人或物,常與of連用。例如:

All of us are here.=We are all here. 我們都在這兒。

[答案] 選C。(all of 后接名詞時,名詞前要用定冠詞the, 故排除A項;定冠詞應(yīng)放在all 之后,故B也錯誤;all 作形容詞,修飾名詞時要放在名詞前,所以D項也不對。)

2.[考題] I found some boys ____ on the playground when I passed No. 19 Middle School.

A. playing the football B. play football C. to play football D. playing football

[要點] found 是find 的過去式,意為“發(fā)現(xiàn)”,句型“find sb. doing sth.”指“發(fā)現(xiàn)某人正在做某事”,這里動詞-ing 形式作find 的賓語補足語,表示動作正在發(fā)生。例如:

On her way home, she found a little girl crying. 在回家的路上,她發(fā)現(xiàn)一個小女孩在哭。

[拓展] find 之后還可接省略to的動詞不定式作賓語補足語,即“find sb. do sth.”句型,表示“發(fā)現(xiàn)某人做某事”,強調(diào)發(fā)現(xiàn)這個動作的全過程。例如:

I found him open the window. 我發(fā)現(xiàn)他打開窗戶了。

[答案] 選D。(play football 是固定短語,football 前不加定冠詞,可先排除。根據(jù)句意“當我路過19中學時,發(fā)現(xiàn)一些男孩子正在踢足球”,可知動作正在發(fā)生。故選playing football。)

3.[考題] I think well have great fun ____ the hill tomorrow.

A. climb B. to climb C. climbed D. climbing

[要點] have fun doing sth. 意為“做某事很開心”,其中fun 是不可數(shù)名詞,fun 前面常用great, much, a lot of 等詞語修飾。例如:

Many people have great fun playing football. 很多年輕人踢足球很快樂。

[拓展] have fun with sth. 表示“做某事有樂趣”。例如:

We have fun with English and Chinese. 我們學英語和語文有很多樂趣。

[答案] 選D。(have fun doing sth. “做某事很開心”是固定句式。)

4.[考題] My watch doesnt work, so I decided ____ ____ (buy) a new one.

[要點] decide to do sth. 表示“決定做某事”,decide 后要用動詞不定式作賓語,變?yōu)榉穸ň鋾r在to前加否定詞not。例如:

Peter decided to go on Monday. 彼得決定星期一走。(肯定句)

The boy decided not to become a doctor. 這個男孩決定將來不當醫(yī)生。(否定句)

[拓展] decide (動詞)的名詞形式為decision, 常用短語為make a decision 做決定。例如:

He has made a decision. 他已經(jīng)做了決定。

[答案] to buy (句意“我的手表壞了,我決定買一塊新的。”)
