九下英语复习(9B Units 3~4)资料

【考点精讲】

一、核心词汇

1.whatever pron.

[考点点拨] whatever意为“任何,一切事物”,主要有两种用法:

(1)引导名词性从句。如:

Whatever she did was right.

她做的一切都是对的。

(2)引导让步状语从句,此时相当于no matter what。如:

Whatever we said, he disagreed.

=No matter what we said, he disagreed.

无论我们说什么,他都不同意。

2.satisfy vt.

[考点点拨] satisfy动词,意为“满足,使……满意”。如:

Though this is an attractive image, it somehow doesn't satisfy.

虽然这是一个有吸引力的形象,但不知为什么,它并不令人满意。

satisfied形容词,意为“满意的;满足的;毫无疑问的;确信的”.be satisfied with意为“对……满意”。如:

John's mother is satisfied with his progress in English.

约翰的妈妈对他在英语方面的进步感到很满意。

3.mess n.

[考点点拨] mess为可数名词,常用单数形式,意为“杂乱,不整齐”。常用的搭配有:be in a mess杂乱无章;make a mess搞得一塌糊涂。如:

She always makes a mess of things.

她总是把事情弄得一团糟。

4.pill n.

[考点点拨] pill意为“药片;药丸”,in the form of pills以药片的形式。

5.polluted adj.

[考点点拨] polluted形容词,意为“被污染的”;pollute动词,意为“污染”;pollution名词,意为“污染”。如:

Cars not only pollute the air in cities, but make the roads crowded.

汽车不仅污染城市空气,而且使道路拥挤不堪。

The air pollution is harmful to our health.

空气污染对我们的健康有害。

二、核心句型

1. After a few comfortable weeks, however, things started to go wrong.

然而,几周舒适的生活之后,情况开始不对了。

[考点点拨] go wrong出现问题。如:

Things started to go wrong when they moved to the city centre.

当他们搬到市中心后,问题出现了。

go wrong用于描述机器时,可表示机器“发生故障,出毛病”。如:

Something has gone wrong with the watch.

这块手表出毛病了。

2. It is hoped that people could start all over again and build a better world on Mars.

人们有望能够在火星上重新开始,并且建设一个更好的世界。

[考点点拨]句型“It is hoped that…”表示“……可以指望”,指说话者希望如此。结构为“It+动词的被动语态+that从句”,that从句的内容才是该句真正的主语。若听说的内容是普遍性的、真理性的,则that从句用一般现在时;若发生过了,用一般过去时;若还未发生,则用一般将来时;若带有主观猜测,则可以和情态动词连用。类似结构还有:

It's told that…据告之….

It's reported that…据报道……

It's believed that…普遍相信……

3. The gravity on Mars is only about three-eighths of that on the Earth.

火星上的重力只有地球上重力的八分之三;

[考点点拨] three-eighths 3/8。分数的表示:分子用基数词,分母用序数词;分子大于一,分母加“s”。如:

l/4-a/one-fourth:1/7-a/one-seventh

3/5-three-fifths:6/7-six-sevenths

We have finished three-sevenths of the work

我们已经完成了这项工作的七分之三。

三、重点语法

简单句和复合句之间的转换

1.我们可以用“宾语+宾语补足语”“疑问词+动词不定式”将宾语从句换成简单句;我们可以用动词不定式将结果状语从句或目的状语从句转成简单句。如:

I saw that he was reading the book carefully.

→I saw him reading the book carefully.

我看到他正在仔细读书。

(1)我们可以用“宾语+宾语补足语”将宾语从句转换成简单句。如:

I found that he was very happy.

→I found him very happy.

我发现他很快乐。

注意:和find,notice有相同用法的动词有hear,see,think,watch等。

(2)我们可以用“疑问词+动词不定式”将宾语从句转换成简单句。如:

I do not know what l will do tomorrow.

→I d o not know what to do tomorrow.

我不知道我明天要做什么。
