　　Dr. Carl Sagan has been a leader in space exploration. He is an astronomer at Cornell University and director of the Laboratory for Planetary Studies. The author talked with Dr. Carl Sagan about how he became an astronomer.

　　Q: At the age of five did you know what the stars were?

　　A: I didn't know what they were, so I asked my friends and some older children, I got answers like “They're lights in the sky, kid.”That wasn't much of an answer. What were they? Were they little electric light bulbs(燈泡) held by black wires you couldn't see?

　　Q: If there are creatures living on another planet, what do you think they would look like?

　　A: I can't imagine what they'd look like, and they couldn't imagine what we'd look like. All of life on Earth is the same, except for some external(外部的) differences in form. Every one of us on Earth, from bacteria(細(xì)菌) to human being; is made up of the same kinds of proteins and the same kinds of nucleic acids(核酸). But on another planet, everything is different, and I would expect that the organisms would be totally different from us.

　　Q: Do you think we should have a manned mission(工作團(tuán))to Mars?

　　A: I don't think there's any reason to send people to Mars if our goal is to find out about Mars. Let's send robots instead. They're cheaper. There's no risk of human lives. Robots can go to more dangerous places. But I think there are reasons for sending people there that are not connected to finding out about Mars. Planning for a manned mission to Mars would force us to improve some of our technology. It would encourage the major technological nations to come together for the project. Space flight also speaks to something deep within us. A human mission to Mars would provide a sense of adventure. It would help to stimulate a new generation of scientists, and it would make all people feel a little more optimistic about what we can do as a planet.

　　Q: What advice would you give a young person who wants to be an astronomer?

　　A: I'd say,“Study physics. But before you can study physics you have to know mathematics, so study mathematics.”I would also encourage them to read a lot, be curious, and ask questions.

1．As a boy, Carl Sagan didn't ________.

[　　]

A．often ask questions

B．a(chǎn)lways get satisfying answers from his friends

C．try to do well in physics

D．read a lot

2．We human beings are interested in finding life on another planet because ________.

[　　]

A．we are naturally drawn to other things that are alive and are curious about them.

B．most of us want to have more friends.

C．some of us are eager to rule the universe

D．scientists want to show how modem our technology is

3．Robots can be sent to Mars because ________.

[　　]

A．we have enough robots

B．they're strong and big

C．everything is easy to them

D．some duties are too dangerous for human being to fulfill

4．A manned mission to Mars ________.

[　　]

A．is reasonable if the goal is to collect information

B．is O.K. if robots are sent as well

C．can make us improve some technology to prepare for it

D．can make strong nations come together

5．Which of the following statements is true?

[　　]

A．Carl Sagan is an astronaut.

B．Carl Sagan used to ask friends silly questions.

C．Carl Sagan thinks we can't imagine what creatures on another planet look like until they can imagine our appearance.

　　Increasing fluid intake(攝入量)by about a liter per day appears to have no negative effects on healthy older men．Dutch researchers report．

　　Dr．Mark G．Spigt of Maastricht University and his colleagues note that older people are often dehydrated(脫水)，partly because their sensation of thirst may be slow．On the other hand, the elderly can easily become overly hydrated, because their kidneys(腎)tend to work less efficiently．Keeping extra water reduce the level of sodium(鈉)in the body, which can have serious consequences．

　　To investigate the general effects of increased fluid intake, the researchers examined data from a study involving 141 healthy men aged between 55 and 75．In random(隨意的)order they were either advised to increase their water intake by a liter and a half per day, or were given a spoonful of syrup(糖漿)per day．

　　After 6 months, the men urged to drink more water had managed to boost their daily fluid intake by an average of about a liter per day．There were no significant differences between the two groups in blood pressure or sodium level．

　　The researchers thus concluded that the advice to increase fluid intake had no negative effects．

　　Summing up, Spigt added,“It seems unreasonable to worry about the harmful effects of drinking extra water, he warned,”This does not mean that one can drink too much．Extreme intakes of water-more than 10 liters–can be harmful．

　　Would you eat a ready meal from the fridge rather than cook from scratch?Have you been doing internet shopping rather than going to the stores?What can’t you be bothered to do?

　　A study into how lazy British people are has found more than half of adults are so lazy they’d catch the lift rather than climb two flights of stairs．

　　Just over 2000 people were quizzed by independent researchers at Nuffield Health, Britain’s largest health charity．The results were astonishing．

　　About one in six people surveyed said if their remote control was broken, they would continue watching the same channel rather than get up．

　　More than one third of those questioned said they would not run to catch a bus．Worryingly, of the 654 respondents with children, 64％ said they were often too tired to play with them．

　　This led the report to conclude that it’s no wonder that one in six children in the UK are classified as obese(very fat)before they start school．

　　Dr Sarah Dauncey, medical director of Nuffield Health, said：“People need to get fitter, not just for their own sake, but for the sake of their families, friends and evidently their pets too．”

　　“If we don’t start to take control of this problem, a whole generation will become too unfit to perform even the most rudimentary of tasks．”

　　And Scotland’s largest city, Glasgow, was shamed as the most inactive city in the UK, with 75％ surveyed admitting they do not get enough exercise, followed closely by Birmingham and Southampton, both with 67％．

　　The results cause serious challenges for the National Health Service, where obesity-related illnesses such as heart disease and cancer have been on a steady increase for the past 40 years and are costing billions of pounds every year．

(1)

What causes children in the UK to be obese?

[　　]

A．

Eating ready meal

B．

Watching TV

C．

Doing Internet shopping

D．

Being lazy

(2)

What can be inferred from the passage?

B．

Internet shopping will do harm to your health．

C．

Many people would not run to catch a bus in Britain．

　　The success of James Cameron's science-fiction blockbuster(賣(mài)座的大片), which has already taken more than ＄1 billion(￡600 million)at the box office, is fuelling a surge in popularity for three-dimensional movies and new 3D television sets．

　　But prolonged viewing may result in an aching head, according to Dr Michael Rosenberg, an ophthalmology(眼科學(xué))professor at Northwestern University Feinberg School of Medicine in Chicago．

　　He said："There are a lot of people walking around with very minor eye problems, for example a minor muscle imbalance, which under normal circumstances the brain deals with naturally．"

　　Watching a 3D movie confronts viewers with an entirely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," he said．

　　Dr Deborah Friedman, a professor of ophthalmology and neurology(神經(jīng)學(xué))at the University of Rochester Medical Center in New York, said："If your eyes are a little off to begin with then it's really throwing a whole degree of effort that your brain now needs to exert．This disparity for some people will give them a headache．"

　　Experts say there are no studies tracking how common it is to get a headache after watching a 3D film．

　　Rick Heineman, a spokesman for RealD, which provides 3D equipment to cinemas, said headaches and nausea were the main reasons 3D technology never took off before．

　　But he said new digital technology addresses many of the problems that had previously caused sore heads．
