in the group to be able to resist new illnesses.

2. Why is it wrong to clone an extinct animal if it would live in a zoo? It is not a good idea to clone an animal that would live in a zoo because it is not a suitable habitat to develop and increase its numbers.The zoo is not a natural environment for a wild animal.

3. Why can’t you clone the DNA of animals that have been extinct longer than 10,000 years? The DNA of animals more than 10,000 years old is not suitable for cloning, for it can’t survive so long.

One possible version【范文】
Together with the modern advances in science

and technology, the news that Dolly had been
born was announced in 1997.

However, Dolly’s death raised many opinions
about cloning. Personally, I would like to agree

that cloning may do no good to our human
beings.

Firstly, seeing Dolly, we may think that cloning animals can easily develop a disease.

They can’t live long. Secondly, we can’t clone
animals that have been extinct longer than

10000 years, even if the DNA of dinosaurs
could survive this long. Thirdly, based on

what we know now, human cloning is just
a matter of time.

But the assumption that human clones have already been born hasn’t been proved yet. In one word, personally, the chances of cloning animals and cloning human beings living on the earth naturally are merely a dream.

Language Points
1. The popularity of the film Jurassic Park, in which a scientist clones several different kinds of extinct dinosaurs, proves how the idea struck a mixture of fear and excitement into people’s heart. 电影侏罗纪公园的受欢迎证实了普通人对 这一话题是多么感兴趣, 在该电影中一位 科学家克隆了几种不同的绝种恐龙。 本句是一个复合句, in which引导非限制 性定语从句, 修饰 “the film”; how引导宾语 从句, 作prove的宾语。

Many people who had seen the film were afraid to go to the forest when they A remembered the scenes _____ people were eaten by the tiger. (05, 广东) A. in which B. by which C. which D. that

解析: 答案A。题意为“很多看过这部电影的人, 当回想到人被老虎吃掉的情景时, 就不敢去森林 了”。本题考查“介词+关系代词”引导的定语从 句。“people were eaten by the tiger”是定语从句, 先行词 the scenes在定语从句中作地点状语, 表示 “在这种场景中”所以选A。

1. strike vt. & vi.打,撞击,冲击,罢工,打动,划燃, 侵袭,突然想起 n.罢工,打击 strike...into one’s heart 使??刻骨铭心 be struck with(by)为??所侵袭; 为??所触动(感动) It strikes me that...我觉得??;我的印象是??

(5)Great damage has been caused by the tornado

上周侵袭这一地区的龙卷风造成了巨大的损失。

【辨析】strike/hit/beat/knock
这四个词均有“打”的意思。 (1)strike 通常表示“打一下、打若干下”,丌 一定都是有意的;还有“打动,使??着迷, 某种想法突然闪现在脑海里”的含义;也可指

“打、擦出(火),(蛇、兽)抓、咬,(钟)敲响”。

2)hit 指“打中”“(对准??来打”“敲打戒打击对方

的某一点”,还可用来表示传染病戒自然灾害“袭击”
某一地区,而其他动词一般丌这样用。作“被??想起”

讲时,不 strike 同义。
(3)beat 侧重“连续地打击”,如殴打戒体罚;也指在

游戏、竞赛戒戓争中击败对方;也指“心跳”。
(4)knock 侧重于“敲打,叩击”,常用做丌及物动词, 通常不 at 连用。
