We are going to talk about the use of genetic technology. Through scientific discoveries, we have known that many diseases exist due to DNA changes. Scientists not only have found out the kaput genes but also repaired them. They can put normal genes in the places of diseased genes in patient's cells or shut down these diseased genes, and as the result, the diseases, especially hereditary diseases, will be cured. This technology was used in 1990 in U.S.A for the first time. Now scientists are searching the genetic way to cure diseased fetus. The genetic technology is also very important for medicine. Genetic medication is the representation of the DNA-recovering. These medications are proteins which can, say, help the increase of red blood cells. Then diseases can be healed without operation. The molecular evolution is the newest genetic technology today. It imitates the natural evolution of organism so to create new genes and proteins which can cure diseases such as the cardiac muscle disease.

about 40% of agricultural products in the USA are genetically engineered, and most people buy them without any worries. But in the Europe the GM food isn't very popular because of its unknown side effect which is a negativefactor to promote GM food.

Chinese tend (seem) to think that this situation was caused by the profit consideration in the USA and Europe, and that's why the Europeans are against GM food. Because U.S. is the biggest investor in the area of the genetic food, the law says that you can only buy genetic seeds, but you can't bring them under cultivation. Therefore the market is monopolized by the USA.

原文写得不错，尤其是开始两段。

简单改了一下。不懂专业，可能有错，特别是最后一段。 仅供参考。
