『壹』 誰有高中英語必修二unit4的一篇課文，animal extinction,給個文檔文件，謝謝！
Many animals have disappeared ring the long history of the earth.The most famous of these animals are dinosaurs.They lived on the earth tens of millions of years ago,long before humans came into being and their future seemed secure at that time.....Dinosaurs died out suddenly about 65 million years ago .Some scientists think it came after an unexpected incident when a huge rock from space hit the earth and put too much st into the air.Others think the earth got too hot for the dinosaurs to live on any more.Nobody knows for sure why and how dinosaurs disappeared from the earth in such a short time .

『肆』 英語必修二第四單元的知識點
1．suggest
【原句回放】but I』d like to help as the WWF suggests. (Page26)
【點撥】suggest vt. 建議，提出，使想起，暗示
1) 接名詞、代詞或動名詞
That girl's sun-tanned face suggests excellent health.
He suggested going out for a walk.
2) 接從句，構成：
It is suggested that... 有人提議……
I suggest that... 我覺得/認為
The doctor suggested that I (should) come again next day.
【拓展】
1) 當suggest表「建議」時，從句中要用虛擬語氣；當suggest表「暗示」，從句中用陳述語氣。
如：He suggested that the meeting（should）be put off. 他建議這個會議應該推遲。
His expression suggests that he didn』t sleep well last night.
他的表情說明他昨晚沒睡好。
2) suggest的名詞為suggestion，其後接表語從句或同位語從句時，從句中也用虛擬語氣。
如：My suggestion is that we（should) add some sand to the soil. （表語從句）
His suggestion that you（should）eat more vegetables to lose weight is reasonable.
(同位語從句)
【隨時練】
He came to my class every week, but his attitude ______ he was not really interested in the subject.
A. expressed B. described C. explained D. suggested
【答案與解析】D。題乾的意思是「他每周來我班裡，但他的態度表明他不是真的對這門課程感興趣。」比較四個詞的意思：expressed「表達、表述」；described「描寫」；explained「解釋」；suggested「暗示、表明」。
2．die out
【原句回放】 As a result these endangered animals may even die out. (Warming up)
【點撥】die out
1）滅絕，絕種
Elephants would die out soon if men were allowed to shoot as many as they wish.
如果人類可以如願地射殺掉大量大象，那麼大象將會很快滅絕。
2）逐漸消失
Many old customs are dying out. 很多老的習俗將要逐漸消失。
3）熄滅
The fire died out in the end. 火最後熄滅了。
【拓展】die away （聲，光，風等）漸弱
die off （家庭成員，種族等）相繼死亡，草木枯死。
die down （火，興奮等）漸弱，漸息
die of 因……而死(死於疾病、情感等)

A. dying out B. dying off C. dying of D. dying from
2. The practice of children working in factories has nearly ______.
A. died off B. died out C. died D. died down
【答案與解析】1.A 2.B
1. 句意為: 現在一些動物有滅絕的危險。 die off 是指多個主體的相繼死去。C,D兩項後要接賓語。
2. 根據拓展，題意應解釋為「幾乎消失」。die down是聲音等逐漸消失，不合題意。。
3．affect
【原句回放】It contains a powerful drug which affects mosquitoes. (P26)
【點撥】 vt. 影響, 感動, 侵襲
如：Smoking affects health. 吸煙影響健康。
We were deeply affected by the news. 我們深深被這消息所感動。
【拓展】affect和effect用法辨析：
1）effect是名詞，意為「結果」、「效力」、「影響」，常用在 have effect on等片語中。如：
The medicine has little effect on the old man. 這葯對那老人幾乎沒有效果。
Punishment almost had no effect on the naughty boy. 懲罰對這個頑皮的孩子幾乎沒有用。
come into effect 開始生效，開始實施
have an effect on 對……有影響； 對……起作用，產生效果
in effect 正在實行
2）affect 指「產生的影響之大足以引起反應」,著重「影響」的動作, 有時含有「對......產生不利
影響」的意思。
如：The rise in prices will affect all classes. 價格的漲幅將會影響到各階層的人。
The climate affected his health. 氣候影響了他的健康。
【隨時練】
The incident ______ the relations between the two countries.
A. affected B. effect C. effort D. had an effect
【答案與解析】A。該題基本為詞義辨析，結合句子意思最關鍵。「這個事件影響了兩個國家的關系」，句子需要謂語。
4．with的復合結構
【原句回放】There Daisy saw an antelope looking sad.(P26)
【點撥】原句可換為There Daisy saw an antelope with a sad face looking at her.
「with+復合賓語」即「with+賓語+賓語補足語」的結構。
眾所周知，能夠充當with的賓語的通常是名詞和代詞，問題的關鍵是賓語補足語的形式，結構如下：
1) with +賓語 +形容詞
You mustn』t sleep with the door open.
2）with +賓語+ 副詞
He has a bad habit of sleeping with the light on.
3）with +賓語+ 介詞短語
A woman came in with a baby in her arms.
4）with +賓語+不定式
With so much work to do, he could not go home.
5）with +賓語+現在分詞
Coming into the school, we may find rows of classroom with trees standing in front of
them.
6）with +賓語+ 過去分詞
With the task completed, we may have a good rest now.
【拓展】「with+復合賓語」在句中的作用
1)「with+復合賓語」結構在句中主要作狀語。
如：With the old man leading, the soldiers started toward the mountains.
在老人的帶領下，士兵們開始向山裡進發。
Two soldiers stand at the gate with a gun in their hands.
兩個士兵手裡拿著槍站在大門口。
2)「with+復合賓語」結構可在句中作定語。如 ：
The room with the window half open is my bedroom. 那個半開窗戶的屋子是我的卧室。
There were rows of white houses with trees in front of them.
在白色的房子前面有很多排樹。
【隨時練】
______ proction up by 60%, the company has had another excellent year.
A. As B. For C. With D. Through
【答案與解析】答案C。選項和後面的名詞及副詞up構成with復合結構。整句意思為「產量增長了60%，公司又經歷了一個極好的年頭。」其他詞不能構成此結構。
5．peace
【原句回放】About 30—40 remain after being left in peace with no hunting.（Warming up）
【點撥】peace
1）安靜，平靜
Don』t disturb her. Just leave her in peace for a while.
不要打擾她，讓她安靜一會兒。
There was a short peace, but then another war broke out.
短暫的和平後又有一場戰爭爆發。
2）治安
The UN troops were busy keeping the peace in that area.
聯合國部隊正忙於維持那個地區的治安。
3）和解，和睦
We tried to make peace with them.
我們試圖和他們和解
【拓展】in peace 和平地，安心地
at peace 平靜地

peaceful adj. 安靜的
【隨時練】
It is our hope that the two countries will live ____ forever.
A. in a peace B. in peace C. peaceful D. in peacefully
【答案與解析】B。從句的意思是「兩個國家永遠和平相處」。A項的結構是不正確的；因為空白處要填狀語，故C項不正確；D項，把in 去掉就可以了。
6．contain
【原句回放】It contains a powerful drug which affects mosquitoes.(P26)
【點撥】contain
1）包含；裝有
This book contains all the information you need. 這本書包含所有你需要的信息。
2）容納
The hall can contain 500 people. 大廳能容納500人。
3）抑制
She couldn』t contain herself for the joy. 她高興得難以自製。
contain 和 include
contain 指作為組成部分而被「包含」或「容納」。
include 指作為整體中的一部分而被包括進去，使用「句子，including +被包括部分」。
【隨時練】
1. In the accident, five passengers were killed, ______ a foreigner.
A. including B. included
C. include D. which were included
2. The bag ________ a lot of books ___________ some English books and history books.
【答案與解析】1. A 2. contains；including
1. 本題考察的是include的一種特殊用法。從句子結構來說，已經有了主語和謂語，空格中就不應是謂
語，而是非謂語動詞。此處including 可以看作介詞用法。
2.書包中「裝有」許多書籍，有容納之意，故首空填contain。
7．protect...from
【原句回放】I』m protecting myself from mosquitoes. (Page 26)
【點撥】protect...from 保護……免受……危害
protect sb./ sth. from + n
protect sb./ oneself from +doing

give /provide protection 提供保護
【隨時練】

A. on B. to C. against D. with
【答案與解析】C。本題考查的是protect 與介詞from 或against 連用的用法。表示「免遭」。
8．reserve

修；retain保持，保留； sustain 支撐，供養。
