As the supply of genetically modified (GM)food increases, many people are unaware that some food they are eating is a product of the GM process. Scientists in a laboratory have artificially changed food by copying genes from one cell and putting them into another cell in order to achieve some supposedly desirable result.
Nowadays, there are a variety of GM foods being produced—such as soybean, nuts, and potato. The reason for the modification process is to make these foods resistant to insects and viruses so that farmers do not need to use much herbicide (除草剂). Taking the example of tomatoes, which are sensitive to the weather, they can be inserted with genes from a type of fish that lives in very cold seas so as to survive frost.
Its supporters argue that GM technology is the future of food and has many advantages. They assert that because of GM food’s stronger resistance to nature’s forces, farmers can produce better harvests. Moreover, it can increase the worldwide supply of food, which can in turn help those areas suffering from food shortages. In addition, common food such as bananas and tomatoes can be injected with vaccines for illnesses to help prevent the spread of serious diseases.
Nevertheless, there has been increased concern about the dangers of GM food. Some people have an unusual reaction to specific proteins called allergens (过敏原). Nuts and soybeans are two of the major sources of these allergies, and reactions to these foods can be life threatening. In addition , the ecosystem might be destroyed by the GM process—the practice of feeding animals with GM crops could lead to health problems related to growth or metabolism (新陈代谢).
The U. S. , Canada, and Argentina, the world’s three largest producers of GM foods, have challenged countries that protect against GM products. Meanwhile, the EU has urged for a wise and careful approach to this matter, labeling products containing GM elements, and some European companies have stopped using GM ingredients. GM food is a complex issue associated with both benefits and risks. The debate on it will continue until we fully examine the long-term consequences.
Questions 71—75
Complete the summary with a maximum of two words from the passage, changing the form where necessary.
Genetic modification refers to the process of copying genes from one cell and putting them into another cell, which is aimed at 【R1】______some supposedly desirable result. More and more genetically modified (GM)food is being produced. It can be 【R2】______ to nature’s forces, insects and viruses, and benefit farmers and areas that 【R3】______food shortages. Although it has many advantages, there is also increased concern about it. Some countries produce GM foods, while others take measures to 【R4】______GM products. The debate on it will not stop until the long-term consequences are 【R5】______. [br] 【R2】
选项
答案
resistant
解析
(根据文章第三段的第二句话可知,由于转基因食品对自然力量的抵抗力更强,农民可以生产更好的作物。故填形容词resistant。)
