　　There are many ways in which human cloning is expected to benefit humans.
　　Dr Richard Seed, one of the leading supporters of human cloning technology, suggests that it may someday be possible to completely change the aging process because of what we learn from cloning.
　　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. Heart disease is the number one killer in the US and several other industrialised countries.
　　There has been a breagh with human stem cells. Embryonic stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, and kidneys could be produced. By combining this technology with human cloning technology, it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimer¡¯s disease, Parkinson¡¯s disease, heart failure, and other problems can be cured if human cloning and its technology are not banned.
　　Though current treatments for infertility (²»ÉúÓý) are getting a fair amount of publicity in the news, they, in terms of percentages, are not very successful. Some data shows that current infertility treatments are less than 10 percent 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 possible.

　　C£®most people in industrial countries suffer from heart disease
　　D£®more people die of heart disease than of other diseases in the US
　　3£®What is the main idea of the last paragraph?
　　A£®With cloning infertile couples could have children.
　　B£®Treatment of infertility is not successful.
　　C£®Infertile couples suffer a lot physically and mentally.
　　D£®It is difficult for couples to have more children now.
　　4£®If a patient is treated with an organ cloned from his own stem cells, ________.
　　A£®he will suffer from heart failure
　　B£®he is more likely to develop other diseases
　　C£®he won¡¯t be likely to catch other diseases
　　D£®his immune system won¡¯t reject the new organ

　　First impressions are important as everybody says. If you like the person within the first nine minutes of your first meeting, it is likely that the sense of a ¡°good fit¡± will endure for a long time.
　　Don¡¯t buy fancy new clothes. Dress in a way that doesn¡¯t call attention to itself. Blacsers or a black skirt and comfortable shoes are OK.
