　　2022年專升本部分省份政策都已經(jīng)公布，英語科目對于大家來說是非常重要的，好學(xué)校小編為大家整理了專升本英語的練習(xí)題及答案，2022年參加專升本的同學(xué)可以練習(xí)下。

　　閱讀理解：

　　Human cloning(克隆) technology could be used to reverse heart attacks. Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged, and other problems may be solved if human cloning and its technology are not forbidden.

　　With cloning, infertile couples could have children. Current treatments for infertility, in terms of percentages(百分比)， are not very successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before. We should be able to clone the bone marrow(骨髓) for children and adults suffering from leukemia(白血病). This is expected to be one of the first benefits to come from cloning technology.

　　We may learn how to switch cells on and off through cloning and thus be able to cure cancer. Cloning technology can be used to test for and perhaps cure gene-related diseases. The above are just a few examples of what human cloning technology can do for mankind.

　　This new technology promises unprecedented advancement in medicine if people release their fears and let the benefits begin.
