1、學(xué)必求其心得，業(yè)必貴于專(zhuān)精unit 3 science versus nature cloning： where is it leading us?cloning has always been with us. it is a way of making an exact copy of another animal or plant. in 1996, the scientists succeeded in cloning dolly the sheep. on the one hand， the whole scientific world paid close attention to

2、 the growth of the first successful clone, dolly the sheep。in general the scientists were praised for their wonderful scientific breakthrough. on the other hand, dollys appearance raised a storm of objections. it suddenly opened everybodys eyes to the possibility of using cloning to produce valuable

3、 tissues and organs that could be used to save human lives.however, some scientists have adopted the technology with the intention of cloning human beings although it is illegal in the majority of countries. human cloning has aroused a lot of anxiety.many people insist that if we toy with life， we m

4、ight create problems.from my point of view, i am not in favour of human cloning。 we must be responsible for the consequences of our actions. we ought to be very cautious about human cloning。 when we make a decision whether we clone human beings or not, everything should be taken into consideration.i

5、n brief， we can push ahead with the technology of cloning to meet our needs instead of destroying our life。克隆:將我們引向何方？克隆一直與我們同在.這是一種用來(lái)生產(chǎn)與原型完全相同的動(dòng)植物的方法。1996年，科學(xué)家們成功克隆出多莉羊.一方面，整個(gè)科學(xué)界都在關(guān)注著首例成功的克隆動(dòng)物多莉羊的成長(zhǎng)。從總體上來(lái)說(shuō)，科學(xué)家們因?yàn)槠浣艹龅目茖W(xué)突破而得到了人們的稱(chēng)贊。另一方面，多莉的出生引起了一陣強(qiáng)烈的反對(duì).它突然打開(kāi)了人們的眼界，看到了有可能利用克隆技術(shù)來(lái)生產(chǎn)能夠用來(lái)拯救人類(lèi)生命的寶貴的組織和器官。然而，有些科學(xué)家已經(jīng)采用這一技術(shù)目的是克隆出人類(lèi)，盡管在大部分國(guó)家這是不合法的?？寺∪祟?lèi)已經(jīng)引起了很多擔(dān)憂(yōu)。很多人堅(jiān)持認(rèn)為如果我們把生命當(dāng)作兒戲，我們可能會(huì)制造很多問(wèn)題。從我個(gè)人觀(guān)點(diǎn)來(lái)看,我不贊成克隆人類(lèi)。我們應(yīng)當(dāng)為我們行為的后果負(fù)責(zé)。我們應(yīng)當(dāng)謹(jǐn)慎對(duì)待克隆人類(lèi)。當(dāng)我們決定是否克隆人類(lèi)的時(shí)候，我們應(yīng)該把各種因素考慮在內(nèi).簡(jiǎn)言之，我們可以努力推進(jìn)克隆技術(shù)來(lái)滿(mǎn)足我們的需要而不是破壞我們的
