问题 In the following article, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list [A]-[G] to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the blanks. Mark your answers on ANSWER SHEET 1.
    In February of 1997 Dolly, the first successful mammalian clone, was born in Edinburgh, Scotland. With the extensive news coverage of this momentous event, the study of genetic engineering and recombinant DNA was thrown into the public spotlight.
    (41)__________Much of this unfounded fear is based upon memories of poorly researched science fiction novels, fear of the unknown, and a "growing mistrust of science".
    (42)__________For example, it will be possible for cows to be genetically engineered to produce pharmaceuticals in their milk. This means that vaccination shots and pills would become obsolete. Babies could be brought up immune to diseases by simply being fed this milk. Imagine the impact on the quality of life for people who live in third world countries like Somalia. Whole countries could be made healthy and immune to disease.
    (43)__________Rice does not provide all of the nutrients that the body needs and in these countries other food is very scarce. If rice or bread, another major staple, are genetically engineered to contain additional necessary vitamins and minerals then we could go a long way towards wiping out malnutrition all over the world.
    (44)__________Organ transplants and cosmetic procedures, like silicone breast implants, that may cause disease would soon cease to exist. Instead of using materials foreign to the body for such procedures, doctors will be able to manufacture bone, fat, connective tissue, or cartilage that match the patient’s tissues exactly, thus ensuring that the needed tissue will be free of rejection by their immune system. Victims of terrible accidents that deform the face and body would be able to have their features repaired with new, safer technology.
    (45)__________
    Throughout time people have always been afraid of new technology and the power it might possess. When the car was first invented some contemporary scientists were convinced that the human body could not survive at speeds as high as twenty miles per hour. At one time birth control pills, in vitro fertilization, and heart transplants were criticized on the same grounds.
    Genetic engineering is an extremely new aspect of our technological research and should, at all costs, be allowed to develop further. The immense possible benefits from genetic engineering are endless and should not be overlooked. Genetic engineering, then, is a tool that humans can use to cure many of their problems.
    [A] Even though the risks are great, the beneficial possibilities are endless. Genetic engineering should be allowed to progress because of the potential benefits for the human species outweigh the consequences.
    [B] Scientists are only beginning to explore the dangers and benefits of genetic engineering. Yet, instead of seeing the immense potential benefits, much of the American public is automatically rejecting this field of research.
    [C] Genetic engineering also has the power to cure infertility, which a painful reality that many couples throughout the world face.
    [D] Even with all these miraculous benefits, many people throughout the world feel that the issue of genetic engineering is absolutely preposterous and extremely unethical. Such opinions are understandable, considering that the majority of people are always going to be afraid of the unknown.
    [E] Malnutrition, a common problem in many third world countries where impoverished peoples rely on a single crop such as rice for the main staple of their diet, could also possibly be cured with genetic engineering.
    [F] But perhaps, the area that stands to benefit the most from genetic engineering is medicine.
    [G] Genetic engineering is like performing heart surgery with a shovel. Scientists do not yet understand living systems completely enough to perform DNA surgery without creating mutations which could be harmful to the environment and our health.
选项
答案D
解析 此处是一个承上启下的段落。从上题已知，上段主要讲遗传工程会在医疗上成为更安全的一种技术。下一段第一句意为：在历史上人们一直都惧怕新技术及其拥有的能量。然后用汽车及避孕药的例子做了进一步说明。由此可知，D选项第一句与上段衔接，最后一句又引出下段内容。D选项意为：尽管有了所有这些奇妙的利益，但世界各地的人还是担心遗传工程这个问题是完全荒谬的，是极其不合伦理道德的。考虑到大多数人总是对不知道的事物产生害怕感，这样的观念是可以理解的。
