三、阅读理解
A
The cloning technology has aroused heated discussions among people. Some of them speak highly of the technology by claiming that it offers a way for human beings to conquer their own genetic defects.
★ Others consider it as an ogre (怪物) who will destroy us all in the end.
FOR
◆Equal importance is that women who are single could have a child, using cloning instead of artificial insemination (受精). Cloning could also provide a copy of a child for a couple whose child had died.
◆Another goal of cloning is to produce livestock (家禽) with ideal characters for the agricultural industry and to be able to manufacture biological products such as proteins for humans.
◆Cloning could be used in various ways to benefit the lives of humans.
◆It may provide a way for completely sterile individuals to reproduce. It may provide a way for homosexual couples to reproduce themselves. It probably will provide a valuable basic research and possible spin off technologies related to reproduction and development.
◆Cloning would also mean that organs could be cloned, so it would be a source of perfect transplant organs. This surely would be immensely beneficial to millions of unfortunate people who are expected to lose their lives due to failure of single (or more) organ(s).
AGAINST
◆Cloning would intervene with the normal cycle of life. There would be a large number of identical (相同的) genes, which minimize (使减小) the chances of mutation (变异), and, in turn, evolution — the fundamental reason how living things naturally adapt to the ever — changing environment.
◆With genetic engineering and human cloning it is possible to use these in the arsenal (兵工厂) of ethnic cleansing (清洗) inequality in our society, which would be the beginning of many wars.
◆Another argument against cloning is that it would be available only to the wealthy and therefore would increase social inequality.
◆If the technology were to be so that scientists could transfer human genes into animals and vice-versa, which would heighten the danger of developing zoonoses, diseases that are transmitted from animals to humans. It could create a worldwide catastrophe that no one would be able to stop.
◆Genetic engineering will cause unseen disasters spiraling our world into chaotic darkness.
◆Cloning dead loved ones will not bring them back; they may look like them, but they will have a different personality.

You Are What You Eat
Genetic (基因的) engineering is the scientific change of the genetic material in a living organism. It allows scientists to identify specific genes, to remove them from an organism’s chromosomes (染色体), improve them, analyze them, and possibly clone them, and to then reinsert the changed gene into the original organism, or a completely different organism. Unlike traditional breeding (繁殖), where a desired quality would be bred within the same species, genetic engineering can insert desired ones into organisms of different species. Wow… Did you catch that?
Genetic engineering creates many positive contributions to agriculture. For example, by genetically engineered (GE) foods, anti-cancer agents, minerals and vitamins can be increased. Improved taste, shelf life, and better transport are all possible. Also, GE plants can increase pest and bacterial resistance, therefore, making the food safe for consumers.
But some argue that the possible negative effects outweigh the positives, and critics are starting to voice their concerns. Unlike Europe, in the United States labeling is not required on genetically engineered foods or on foods that contain genetically engineered products. Most Americans do not realize that they are, in fact, eating GE foods.
The public is also concerned about the unknown health risks. With limited understanding of genes, scientists cannot predict possible effects. Because most genes introduced into GE plants come from sources not introduced into the human body, it is impossible to know if they will cause reactions. Moreover, due to the lack of labeling, if allergies develop, it will be extremely difficult to find the origin of them.
There is also a major moral question in many minds. For many, the conflict is not if it is safe or not, but it disturbs them because it is unnatural and unnecessary. We are currently producing one and a half times the amount of food needed to feed the world, yet one in seven people are starving. GE food is unnecessary, and fails to address the root of hunger. Many believe that the only people wh
