[单项选择]Every newborn baby is dealt a genetic hand of cards which helps to determine how long he or she will be allowed to play the game of life. There are good cards, which predispose those who have them to a long and healthy existence, and there are bad cards, which predispose people to high blood pressure, say, or heart disease. Occasionally, cards are dealt out that doom their holders to an early death. In the past, people never knew exactly which cards — in other words, which genes — 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 probe for dangerous genes, has changed all this. But, until recently, if you 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.
S

B. Environmental factors are more important than genes.
C. Genetic factors may contribute to some common diseases.
D. It is common that some genes are directly related to a person’s risk of death.

[简答题]
从2012年5月开始,河南省周口市开始了一项颇受争议的“平坟复耕”工作。到目前为止,已有200多万个坟头先后被平掉。“平坟复耕”之所以备受争议,一是因为其平坟工作缺少相关法律依据;二是几百万民众不愿意,政府就采取强硬措施;三是“平坟”之后“复耕”难得保证,因为很多坟都在山上,无法成为良田。明知平坟不能复耕,为何还要大规模平坟?一是当地农田数量离国务院规定的土地“红线”相差甚远,平坟可保住账面上的农田数量。二是当地财政吃紧,平坟能扩大可卖土地,增加财政收入。2012年11月20日该市“平坟复耕”工作已暂停推行。
结合材料,运用政治生活知识分析周口市“平坟复耕”工作对我国政府的启示。

[单项选择]
It is clear that some people who participate in exercise training will develop injuries to their bones, muscles, and joints (关节). Despite unfounded reports in the mass media of extremely high injury rates among adult exercisers, there have been few good studies of exercise injuries in populations. One of the difficulties in performing such studies has been the need to identify both the number of cases and the number of people at risk for injury. In other words, it is difficult to know the number of individuals injured and the total number of individuals exercising in the population. But these two figures are necessary in order to calculate (统计) true injury rates. Normally, injury is defined as an accident that causes a person to stop exercising for at least one week. The best available studies on injury rates show that about 25 to 30 percent of adult runners become "injured" (based on the above definition) over the course of a year. More serious injuries include those f
A. The amount of exercise.
B. The age, sex and body type.
C. Structural abnormalities.
D. The sudden increases in training intensity.
