发布:2024/11/9 9:0:1组卷:11引用:7难度:0.71246.Astronauts travelling in space meet forms of radiation that are uncommon on Earth.Some of this radiation has been shown to be harmful to human health.It is linked to cancers and heart problems.Yet a new American study suggests the radiation does not shorten astronauts' lives.
Researchers studied nearly 60 years of health records and other data about male astronauts from the United States.They then compared this 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.The findings were reported in the publication Occupational & Environmental Medicine.
Much of the existing research on mortality rates in 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 Robert Reynolds.
Reynolds said, "The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but had never gone to space at all.To do this,we need to find a group that is comparable on several important factors."
(1)How did researchers carry out their study?
A.By doing interviews.
B.By analysing some factors.
C.By comparing different data.
D.By doing experiments in the lab.
(2)What can we learn from the text?
A.All radiation is harmful to human health.
B.Athletes tend to be poorer than most Americans.
C.Healthy worker effect makes working people healthier.
D.Research has explored the mental and physical demands of being astronauts.
(3)What can be inferred from Reynolds' words?
A.Researchers are determined to face the challenge.
B.The research is almost impossible to conduct.
C.Several important factors hold back the research.
D.Astronauts are as healthy as they would be if they haven't been astronauts.
(4)What can be a suitable title for the text?
A.Astronauts-healthy or otherwise
B.Astronauts are as healthy as athletes
C.Radiation affects astronauts' health

"I just got my first A minus," he said.
Year after year,I watch in depression as students are crazy about getting straight A's.Some sacrifice their health;a few have even tried to charge their school after failure.They believe top marks are a ticket to elite graduate schools and rewarding job opportunities.I was one of them.I started college with the goal of graduating with a GPA of 4.0.It would be a reflection of my brainpower and willpower,showing that I had the right things to succeed.But I was wrong.
The evidence is clear:Across industries,research shows that the association between grades and job performance is modest in the first year after college and insignificant within a handful of years.For example,at Microsoft,once employees are two or three years out of college,their grades have nothing to do with their performance.(Of course,it must be said that if you got D's,you probably wouldn't end up at Microsoft.)
Academic grades rarely assess qualities like creativity,leadership and teamwork skills,or social,emotional and political intelligence.Yes,straight A students master large amounts of information and reproduce it in exams.But career success is rarely about finding the right solution to a problem-it's more about finding the right problem to solve.This might explain why Steve Jobs finished high school with a GPA of 2.65,and Martin Luther King Jr.jye.ai only one A in his four years at Morehouse.
(1)Why did Jack feel sad?
A.His girlfriend abandoned him.
B.He was caught cheating in exams.
C.He failed to get straight A's.
D.He didn't hand in his paper in time.
(2)What did the author once believe?
A.It was wrong to care too much about marks.
B.Failure was schools' fault.
C.Marks didn't reflect willpower and brainpower.
D.Top marks meant well-paid job offers.
(3)Why are the employees at Microsoft mentioned?
A.To indicate academic performance is important.
B.To stress the company values employees with top marks.
C.To introduce successful examples in the technology industry.
D.To show academic excellence isn't a strong predictor of career performance.
(4)What should people focus more on to succeed?
A.How to solve a problem.
B.What problem to be solved.
C.How to be a creative leader.
D.What to do with detailed information.发布:2024/11/9 9:0:1组卷:9引用:2难度:0.51248.阻止,制止
