The study of genetics has given rise to a profitable new industry called biotechnology. As the name【C1】______, it combines biology and modern technology through such【C2】______as genetic engineering. Some of the new biotech companies, as they are called, 【C3】______in agriculture and are working enthusiastically to patent(取得专利)seeds that give a high yield(产量), that【C4】______disease, drought and frost, and that reduce the need for dangerous chemicals. 【C5】______such goals could be achieved, it would be most beneficial. But some have raised【C6】______about genetically engineered crops.
"In nature, genetic diversity(多样性)is created within certain limits," says the book Genetic Engineering, Food and Our Environment. " A rose can be crossed(杂交)with a different kind of rose, but a rose will【C7】______cross with a potato... " Genetic engineering, on the other hand, usually involves taking genes from one species and inserting them into another in an attempt to【C8】______a desired property or character. This could mean, 【C9】______, selecting a gene which leads to the production of a chemical with antifreeze properties from an arctic fish, and joining it into a potato or strawberry to make it frost-resistant. It is now possible for plants to be engineered with genes【C10】______from bacteria, viruses, insects, animals or even humans. 【C11】______, then, biotechnology allows humans to break the genetic walls that【C12】______species.
Like the green revolution, 【C13】______some call the gene revolution【C14】______to the problem of genetic uniformity(千篇一律)— some say even more so【C15】______geneticists can employ techniques such【C16】______cloning and organ culture, processes that produce perfectly 【C17】______copies, or clones. Concerns about the biodiversity, therefore, remain. Genetically altered plants, however, raise new【C18】______, such as the effects that they may have on us and the environment. "We are flying blindly into a new【C19】______of agricultural biotechnology with high hopes, few constraints, and little idea of the potential【C20】______," said science writer Jeremy Rifkin.
【C20】
选项
A、navigations
B、mystery
C、outcomes
D、destinations
答案
C
解析
名词词义辨析。little idea of意为“不知道”。navigations“航行,航海”;mystery“神秘”;outcomes“产生,结果”;destinations“目的地,终点”。根据句意,不知道基因技术会带来的潜在结果。故答案为C。
