贝木卧烟远江:一篇需要更正的英文稿子

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.

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。

We want to talk about the use of genetic technology. Through scientific discoveries, we know that many diseases exist [with] the change of DNA. Scientists not only find out the kaput genes but also repair them. They can put normal genes [into] diseased genes of patient’s cells or shut down these diseased genes, then the diseases, especially hereditary disease, will be cured. This technology was used in 1990 in U.S.A for the first time. Now the scientists are researching for the genetic way to cure foetus. So the genetic technology is also very important for medicine. Genetic medication is the representation of the DNA-recovering. These medications are proteins which can e.g. 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 that some new genes and proteins which can cure diseases like cardiac muscle disease are created.
Although 40% of agricultural products in the USA are genetically engineered, [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 should be negative.
The Chinese think it [] were also a profit conflict between the USA and Europe, wherefore the Europeans are against GM food. [While] American is the biggest investor in genetic area and the law [limits people] can only buy genetic seeds, [] [they] can’t bring them under cultivation. Therefore the market is monopolized by the USA.

原文写得很好。
建议在陈述一个事实的时候，不要用you、I之类的代词，用it、these等比较好。
