what is your opinion of genetic engineeringFar-reaching significance of genetic testing: All diseases are genetically related. Genes are DNA molecules carry the genetic information of the function of fragments of biological material to pass genetic information. Genes for life itself, is the root of life, sickness and death. 1, predictive medicine. In health and sub-health era will be able to accurately predict the risk of disease. 2, disease prevention. Disease = internal + external factors. Through the understanding of internal factors, which can effectively avoid the impact of external factors, thereby reducing the risk of illness. 3, health management. Through genetic testing, knowing that they have certain aspects of disease susceptibility genes, we can take the initiative for improving the environment and living habits,
Make their own health management. 4, personalized health care services. Through genetic testing, prompt us to what medicines to be used with caution, not only significantly reduce unnecessary medical expenses, increased efficacy, but also to avoid causing more harm to the human body.基因检测深远的意义： 一切疾病都与基因有关。基因是 DNA 分子上携带有遗传信息的功能片断，是生物传递遗传信息的物质。基因主宰生命，是生命生老病死的根源。 1 、预测医学。在健康和亚健康时期就能够准确预测疾病的风险。 2 、疾病预防。疾病＝内因＋外因。通过对内因的了解，可有效地避免外因的影响，从而可降低患病的风险。 3 、健康管理。通过基因检测，知道自己有某方面的疾病易感基因，就可主动的改善环境和生活习惯，做好自己的健康管理。 4 、个性化医疗服务。通过基因检测，提示我们哪些药物要慎用，不但大大地降低了不必要的医疗支出，提高了疗效，更避免了对人体造成更大的伤害。

Go Out To Travel 时间:2009-05-07 15:10作者: 点击: 16066次 I went to three cities to play during last summer holidays. They are Beijing, Dalian and HuHehot. I went to Beijing more than eight times. Beijing is the capital of China. It’s a big city. I am very familiar with Beijing. It takes an hour and forty minutes from Nantong to Beijing by plane. There are many tall buildings in Beijing. It’s a modern city. My family visited the Great Wall, the Summer Palace, the Palace Museum, the Beihai Park, the Space Museum, etc. I went to the countryside of Beijing to go boating and fishing. It was very interesting. I went shopping in WangFuJing. I bought lots of souvenirs and other things. I like eating Beijing snacks. They are delicious. Don’t miss Beijing Duck. It is really nice. Dalian is a beautiful city. Dalian is close to Beijing. I spent 5o minutes on the plane. Dalian is near the sea. I smelled the salt in the air. The roads are clean. There are lots of trees and flowers near the roads. There are many esplanades and Japanese buildings. There are some fountains in one of the esplanades. Some people flew kites and walked on the esplanades. We went to see the beach and the sea. The sea is blue. There were many swimmers in the sea. I lay on the beach to see the sky. Dalian is a very nice place to live in. Huhehot is in Inner Mongol. There are lots of large grasslands. The grasslands are endless. The sky is bright blue. There were a lot of horses and sheep. They were running or eating grass. I rode a horse on the grassland. I picked some colourful flowers. We drank tea with milk. There is a small desert, it was very hot when I walked on it. The sand could sing. These trips helped me open my eyes. I enjoyed my day.
