Every newborn baby is dealt a hand of cards which helps to determine how long he or she will be allowed to play the game of life. Good cards will help those who have them to have a long and healthy existence, while bad cards will bring to those who have them terrible diseases like high blood pressure and heart disease. Occasionally, cards are dealt out that doom their holders to an early death. In the past, people never knew exactly which cards they had been dealt. They could guess at the future only by looking at the kind of health problems experienced by their parents or grandparents.
Genetic testing, which makes it possible to find dangerous genes, has changed all this. But, until recently, if you were tested positive for a bad gene you were not obliged to reveal this to anyone else except in a few extreme circumstances. This month, however, Britain became the first country in the world to allow life insurers to ask for test results.
So far, approval has been given only for a test for a fatal brain disorder known as Huntington’s disease. But ten other tests (for seven diseases) are already in use and are awaiting similar approval.
The independent body that gives approval, the Department of Health’s genetics and insurance committee, does not have to decide whether the use of genetic information in insurance is ethical. It must judge only whether the tests are reliable to insurers. In the case of Huntington’s disease the answer is clear-cut. People unlucky enough to have this gene will die early, and cost life insurers dearly.
This is only the start. Clear-cut genetic answers, where a gene is simply and directly related to a person’s risk of death, are uncommon. More usually, a group of genes is associated with the risk of developing a common disease, dependent on the presence of other genetic or environmental factors. But, as tests improve, it will become possible to predict whether or not a particular individual is at risk. In the next few years researchers will discover more and more about the functions of individual genes and what health risks — or benefits — are associated with them.
The author’s purpose in writing the passage is
选项
A、to indicate the way genetic testing works.
B、to show the power of one’s genetic makeup.
C、to introduce genetic testing and its function.
D、to reveal the influence of environment on genes.
答案
C
解析
主旨大意题。文章主要介绍了基因测试以及它在检测疾病方面的作用,故[C]最能概括作者的写作意图。[A]只是文章的一个方面;[B]、[D]只分别在第四段和最后一段提及,不是文章的主要内容。
