Speech on cloning
Everything has two sides and cloning is not an exception，i t has both advantages and disadvantages. On the contrary， most people are against of cloning technology been used in our life, One of the biggest reason is that human cloning technology will break the gender balance，it will be bring up a great chaos. As far as I think cloning technology is more m uch disadvantage for human being ,we should very careful to use it, I believe that only in this way our life will be more Beautiful. 任何事情都有两面性,克隆也不例外,它既有优点和缺点。 大多数人都反对克隆技术被使用的，因为我们的生活中 最大的一个原因是克隆人类。克隆技术将打破性别平衡, 它将制造出混乱。我认为克隆技术是人类更多的缺点,我 们应该非常小心使用它,我相信只有这样,我们的生活将更 加美丽的。
cloned animals
Nowadays, rapid development in science and technology makes it possible that we can clone any animal according to our own will, even including ourselves, provided that we master related techniques . 如今,科学在快速发展,我们可以根据我们自己的意愿用 克隆技术克隆任何动物,甚至包括克隆我们自己,只要 我们掌握相关技术。
In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell had been taken from the udder of adult sheep, which show the first cloning experiment was successful.
首先,人口爆炸无疑导致激烈的资源竞争,这将被克隆人类绝对扩展更多。其次,作 恶,如恐怖分子,可能得到它来创建严重的灾难,这是一个重要的元素对克隆中发挥 着举足轻重的作用。最后,它不仅可以摧毁地球的多样性的人但也威胁到人类的健 康。因为如果科学家人类基因转移到动物,可能从动物传播到人类的疾病。总之,这 是完全可能的,即人类克隆将创建一个世界范围的灾难,没有人能够停止。
当克隆技术提高很快,许多科学家 和医生有不同的看法,有人认为它 是不错,但有人认为这是不好的。 克隆可以给人类带来很多好处,如 复兴,对有缺陷的基因,肝功能衰 竭、肾衰竭和白血病。这些疾病 是非常不同的治疗,如果我们使用 克隆技术我们可以改变基因的DNA 顺序,所以我们可以救很多人。但 是克隆还是有一些问题。科学家 们发现,克隆动物的基因有一点不 同于原始的动物。所以会比现实 生活的生活。事实证明,克隆绵羊 多莉已经死亡。它只有一半生活 常见的羊。
利用克隆技术可以在抢救珍奇濒危动物、扩大良种动物群体、提供足量 试验动物、推进转基因动物研究、攻克遗传性疾病、研制高水平新药、 生产可供人移植的内脏器官等研究中发挥作用
Some other uses of clone
Rescue endangered animals. Provide experimental animals and organizations. Produce new productions for humans. Cure and go against some genetic diseases. Contribute to high level new medicines.
Now the cloning scientific has been used for many years to produce plants, it has brought us a lot of benefits but has create d some serious problems as well. The benefit of cloning is cloning human organs or body parts , such as that if a parson in traffic accident lost his arm or leg ,or someone get a serious heart Disease and face danger ,he need a new body parts replace , At this time we can use cloning technology copy a new parts of body to replace ,in the this way can be ensure that someone continue to live ,so that the clone is benefit for us .
Is clone good or not?
Research advances over the past decade have told us that, with little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!
When the cloning technology improves so quickly, many scientists and doctors have different opinions, someone think it is good but someone think it is bad. Cloning can bring many benefits to the human, such as rejuvenation, helpful for Defective genes, Liver failure, Kidney failure and Leukemia. These disease are very different to cure, if we use the cloning technology we can change the Gene’s DNA(Deoxyribonucleic Acid) or der, so we can save lots of people. But cl oning still has some problems. The scientists found that the cloning animal’s Gene has a little different from the original animal. So the life will shorter than the real life. The fact proved that, the cloning sheep D olly has died. It only has the half life of the common sheep.
So, we can clone things, but why would we want to? Let's look at some of the reasons people give to justify cloning.
Using the clone technology may in the rescue precious endangered animal, the expanded improved variety animal community, provides the sufficiency experiment animal, the advancement transgene animal research, to attack and capture the hereditary disease, the development high level new medicine, the production to be possible in internal organs official rank research which transplants for the human to play the role
现在,克隆科学已经使用多年,它给我们带来了许多好处,但也带来了 一些严重的问题。克隆的好处是克隆人体器官或身体部位,例如,如果 一个牧师在事故中失去了他的手臂或腿,或者面对严重的心脏疾病和 危险,他需要一个新的身体部分取代,在这个时候我们可以利用克隆技 术复制一个新的身体部分来代替,这样可以确保一个人继续生活。如 此，克隆对我们有好处。
Do you know who is the first user of cloning ？
Mr. Sun
There is no doubt that the application of clone, to a certain degree, is beneficial to mankind. But we should be conscious of that human cloning has little value i n reality and it even can invite unthinkable destructio n.

The complex st ructure of the brain.B．How changes in the muscles affect the brain.C．The importance of the brain.D．How the brain becomes stronger by learning new things.4．What does the underlined word “perspicacious” in the last pa ragraph probably mean? A．Strong. B．Smart.C．Popular.
