Ⅰ. 阅读理解
Astronauts travelling in space meet various types of radiation that are uncommon on Earth. Some of the radiation has been shown to be harmful to human health,which is linked to cancers and heart problems. Yet a new American study suggests this radiation does not shorten astronauts’ lives.
The researchers studied nearly 60 years of health records and other data about male astronauts from the United States. They then compared the data with information about a group of men who are in good health,richer than most Americans and receive good health care — professional athletes. The study found that neither group has higher rates of dying at a young age. In fact,both groups generally live longer than other Americans.
Astronauts are usually well-educated,earn more money and are in better physical condition than the average American. Some earlier research has linked being an astronaut to a lower risk of early death,the researchers noted.
Much of the existing research on the death rate among astronauts has not yet explored the mental and physical demands of this job. There also has not been a lot of research on whether astronauts show what is known as the “healthy worker effect”. This effect leads people with employment of any kind to have fewer medical problems than people who are unable to work,said a researcher.
The researcher said,“The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but never gone to space at all. To do this,we need to find a group that is comparable in several important factors.”
