However, is it really an option that should be considered as a way to extend hum
7、an life? Reproductive cloning may help human families gain children, but theres also a benefit for the animal world.It brings hope to people eager for children but unable to have their own or adopt. It can also bring about the recreation of species that have long since died, allowing scientists to f
8、ully study the species as a living creature instead of simply looking at images or bones.Many believe that cloning can be used to replace failing organs. This will reduce the waiting list for organ donations and allow more people to be saved. Not only that, but because the organ is, in fact, your ow
9、n organ, there would be less chance of rejection.Cloning could prove helpful in genetic research. Using cloning technologies, genetic researchers would have a better understanding of the composition of genes and the effects of genetic constituents (成分) on human characters. Theres also the possibilit
10、y of changing genetic constituents in cloned humans, and cloning could help fight genetic diseases.While the cloning of body organs can help extend human life, it could also cause a lot of malpractice (玩忽职守). Along with the ability to clone desired characters, there could be the possibility of peopl
11、e deliberately reproducing undesired characters. This could lead to a rise in malpractices within society.Cloning involves a process of creating identical genes. As such, there would be a lack of diversity in humankind. Scientists believe this lack of diversity will lower the human races ability to
12、adapt. Whatever your view on cloning may be, studies show that the clone would in fact not be completely identical to the original just as twins are not completely identical. Though they might look alike, twins have different personalities and enjoy different things. The same could be said of clones
13、. Even if technology were created in which your memories and thoughts could be transmitted (传送) to the clone, your clone would still be a different person.24.

16、 a clone will be like.CMy parents both left school at 14. They could read and write, but except for a quick look at the daily newspaper, reading and writing didnt play a big part in their lives. There were very few books in the house. When I was only 14 years old my father gave me an important lette
17、r that hed written to the bank and asked me to check it for grammar and spelling mistakes. And there were quite a lot. He never wrote letters or postcards or even Christmas cards. So when he had to write he wasnt comfortable or confident. Does that mean that my father had a low level of literacy (读写
18、能力)? I dont think so.There are lots of different definitions (定义) of literacy. Some experts define it as having the reading and writing skills that you need to be independent in your everyday life. So, for example, if you can read instructions, write a cheque, fill in a form anything that you need t
19、o do in everyday life then you are functionally literate.If you live in a society where most people are literate then you will feel ashamed and avoid situations in which you have to read or write. A friends father finally admitted to his family that he couldnt read when he was 45 years old. He had b
20、ought the newspaper every day and pretended to read it. Being illiterate can have a big effect on peoples lives. Worldwide statistics show that literacy problems are associated with poverty and a lack of political power. More women than men are illiterate. Illiterate people have worse health, bigger
21、 families and are more likely to go to prison. So literacy campaigns must be a good thing. But dont forget that an illiterate person, or someone with a low level of literacy, isnt necessarily stupid or ignorant (无知的) and may not be unhappy at all. Knowledge and wisdom isnt only found in writing.28.

But as his family had never grown tea,he had no idea how to do it.Being a layman (外行)in this field, Tenzing went to me
27、et with many tea experts and followed their instructions. But whenever he sprayed pesticide (农药)on his farm, hed get a headache and feel indisposed.
