Is the cloud computing perfect now?Cloud computing, or the cloud, is a colloquial expression used to describe a variety of different types of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet. And with various terminals developing fast, the durative, massive and intricate computing related to these terminals really become urgent problems. And for the present, cloud computing is a solution. But if we allow the cloud computing to contact with our private information, is it secure enough? And in which field can we improve the security? In the Security Benefits of Cloud Computing, Felician Aleca introduced the cloud computing and analyze its extensive application in the Internet field. It clarified many advantages of the cloud computing. In addition, it also introduced some major security benefits for individuals or companies which are provided by the cloud computing. But nearly every Internet technique will produce some latent vulnerability. In an essay about computer hacker, How Do Computer Hackers “Get Inside”a Computer?, by Julie J. C. H. Ryan, it introduced the various ways that hackers use to invade into computer. And there are three major patterns of these ways, which are gaining access to the stored contents of a computer system, gaining access to the processing capabilities of system, or capturing information being communicated between systems (J.C.H.Ryan,2004). And in the end, it reminds the importance of protecting our computer. As we all known, the personal terminals always store many private information, and the cloud store the users’ data on the Internet servers , in this way, it will cause large-scale information leakage once the hackers invade to these servers online. In fact, we are becoming more vulnerable while we enjoy the benefit of centralized processing by cloud computing. So how to improve the security of the users’ data stored in the cloud is real ly worth studying.ReferenceJulie J. C. H. Ryan. How Do Computer Hackers “Get Inside” a Computer?.

学术英语学院名称:材料科学与工程学院学生姓名:***学号:**********专业班级:新能源材料与器件1312015年 6月16 日The current development of genetically modified crops ofChina and its safety issuesZhang Qingfei(College of materials science and engineering, Nanchang University, 10001) Abstracts:GM technology as a new, highly efficient genetically modified technology, already widely used in the cultivation of new varieties of field crops. China's transgenic technology started earlier, China's current GM technology level in the forefront of the world, especially made great achievements in the cultivation of new varieties of crops. In this paper, the status quo using gene transfer on Chinese agriculture and safety of transgenic technology are introduced, and the resolve of GM safety issues some thought. On this basis, I made some new ideas of transgenic technology and application of transgenic technology development prospects were discussed.Keywords: GM technology; GM crops; GM safety issues; ChinaIntroduction:As the core of the biotechnology giant leap .Transgenic technology is known as the second "green revolution." In 1983, the world's first strain of transgenic tobacco plants marks the arrival of the era of gene transfer plants. In the ensuing decades, genetically modified crops developed rapidly. In 2014, there are 28 countries in the world planted GM crops, the planting area has reached more than 180 million hectares, Chinese genetically modified crops planting area is 3.6 million hectares. With the widespread planting of genetically modified crops, the impact of transgenic technology in agriculture is growing. As the research of GM crops, China has made great achievements in the research of rice and cotton.The development of anything will not be smooth. With the development of GM technology, its security deposit issues also be exposed. The safety of genetically modified crops has been disputed by people, opponents argue that GM crops have great potential risk, it should be resisted. What is more, some people exaggerate the risk of genetically modified crops. Aroused people's fear of genetically modified. In this paper, the people of GM crops concerns, the status of the development of GM crops were elaborated. Besides, security problems of genetically modified crops and their solutions will be discussed.The current development of genetically modified crops in chinaGM refers to the Technology that use molecular biology method to transfer the artificial separation and some modified biological gene to other species and change the genetic characteristics of the species .Plant transgenic technology is the genetic transformation of plants, making plants to meet human needs in aspects of shape, nutrition and consumer quality.China's biotech crop improvement research began in the 1980s, during the past 30 years, Chinese agricultural and biological high-tech has been developing rapidly. At present, China's hybrid rice, cotton and other advanced in the world. GM technology Applied on cotton, rice and other crops on behalf of China's development status of GM crops.As a cotton producing countries, the industrialization of Chinese insect-resistant cotton has brought huge economic and ecological benefits to Chinesesociety. Since the 1990 s, China's major cotton producing areas often suffered insect outbreaks and the effect conventional control is poor. In 1994, under the impetus of the country, Bt gene was successfully imported into The main plant cotton species .China has become the second country with the independent development of insect-resistant cotton.In 1999, China began to commercial cultivation of cotton. In 2010, gm cotton planting and product in China reached 3.45 million hectares, accounting for 69% of the total cotton planting and product. The planting of insect-resistant cotton have effectively controlled the damage caused by the cotton bollworm .The insect-resistant cotton also reduced pesticide use, protect the farmland ecological environment.Cotton yield and growth of calendar year in China:China's research on genetically modified (gm) rice have got rich achievements. In August 17, 2009, the Ministry of Agriculture promulgated transgenic rice security certificate for the two anti-lepidopteran pests transgenic rice -----"Hua Hui 1" and "Bt Shan You 63" .In addition, China has produced the anti-amino phosphonic herbicide Bar gene rice lines, the new salt tolerance strains which represented by T22-77. Compared with ordinary rice, these transgenic rice has unmatched superior properties .It will bring huge economic benefits to Chinese farmers if these rice be planted on large-scale .For example, each 667m2 planting salt-tolerant transgenic rice can increase the income of 100 yuan. Transgenic rice can reduce the use of pesticides and fertilizers, which is benefical to the environment.GM soy is the world's first commercialization, promotion and application of the fastest growing GM crops .Dates from Agropages shows that show in 2012 , global soybean acreage reached 107 million hectares, of which GM soybeans accounted for 79 percent (84.5 million hectares). As the world's first four major soybean producing countries, China is planting soybeans which are non-GMO soybeans. The transgenic soybean was still in the research stage, failed to achieve commercial GM soy production and large-scale demonstration.Analysis about safety issuesGM technology could efficiently improve crop yield, quality and resistance to meet growing human material needs. Transgenic technology is a double-edged sword, both its positive and beneficial side, also has its negative, the negative side, The biggest potential hazards of transgenic technology is the escape of target gene and gene pollution. With the genetically modified plants wide spread around the world ,the gene of interest may vary pollen spread to other species, or spread into the environment, which may causing unpredictable results. Canada's "superweeds" event and Mexican’s “corn genetic pollution” incident has sounded the alarm for us. Besides, certain genetic traits like instability of some transgenic plants are instability, transge nic plants’ good traits will become weaken over time. Another possibility is that some transgenic plants will produce some harmful variations which will endanger human health.Effects of transgenic expression products on humans is a problem that people are most concerned about. Some of the transgene expression product will make people allergic to. But for the most expression product we are lack of direct evidence to affirm their effects on human health and the environment.In order to verify the impact of Bt proteins on animal health. Since 1999, scientists feed white mouse with genetically modified food which containing the Bt protein for many years, the results showed that mice genetically modified agricultural products containing Bt protein is safe to the mouse. However, in the short-term animal feeding trials data can not prove the Bt protein is safe to us.Because human is the long-term consumer of rice. Recently, Canadian scientists discovered, Bt proteins can enter any place of the body. Even the in baby's umbilical cord blood were also found the Bt proteins. Therefore, this discovery had to let the people worried about the safety of transgenic Bt crops.Since the transgenic technology used gene beyond the conventional sexual hybridization gene scope, and for the problem that whether transgenic plants will affect human health and the environment or not we are also lack of systematic knowledge and experience .By the current level of science ,we can not be completely accurate prediction of the results of an outer genes in the new genetic background would cause.Currently, the safety evaluation of transgenic plants primarily relates to environmental safety and food safety aspects. The core issue of environmental safety assessment is after transgenic plants released into the field, whether it will evolve into weed, whether the genes will transfer to wild plants drift or not ; whether it will destroy the natural environment and break the original biological populations homeostasis ; whether it will destroy biodiversity, and so on. Ecological effects of GM crops may arise mainly in the gene flow, non-target effects, the target pest resistance evolution, etc.ConlusionFor security issues, by taking the right measures and scientific management system is able to solve these problems. We can improve the safety of transgenic plants from the following aspects:(1) Carrying out propagandas about genetically modified technical and transgenic plants.Cultivating people’s objectivity awareness of security issues to genetically modified(2) Improving the legal system transfer plant genes and their products;(3) The establishment of transgenic crop management technology system and risk assessment system; and(4) Using food processing technology to process raw materials of transgenic food, remove the transgene expression product that exist in the raw materials of transgenic food.In addition to cultivation of crops, we can also use transgenic technology to cultivate some asexual reproduction and non-food plants. This concept have two advantages .On the one hand, it is a good solution to the genes escape and genes pollution problems. Because the escape and contamination of genes mainly through plants’ pollen s, and asexual reproduction plants will not produce pollen. On the other hand, people do not worry about the transgene expression products will affect human health, because these transgenic plants is not food crops. Transgene expression products don’t enters the body. For example, we can cultivate forestry trees which with high resistance; foliage plants which can glowing; Aquatics which can absorb the harmful heavy metals in water and so on. These plants will bring great benefits to humanity. Prospects of transgenic technology is unlimited, as long as strengthen supervision and follow scientific methods, can be avoided completely turn the negative effects of human gene technology may bring.Reference:[1] Deng Xu, Wei Bin, Hu Zhang Li.
