Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation (睡眠不足).

       Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools.They began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night.

       The friends imagined a smart alarm clock that could track how much time people spend in the most restorative (有回复作用的) stages of the sleep cycle: REM (rapid eye movement) and deep sleep.What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists.

       Their company, Zeo, based in Newton, Mass, launched its product in June, 2009.The Zeo device uses a headband with tiny sensors (传感器) that scan your brain for signs of four sleep states- REM, light, deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep (which is when you're least groggy).In the morning you can upload the data to the company's Web site, and so track your sleep over time.Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept.

       "Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO.

       Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm.

       For now the company is selling Zeo online only.Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels.

Who will support Zeo?

       A.People full of imagination.          B.People suffering sleeping problems.

       C.People having access to the Internet. D.People having bad lifestyles.

Why did the three graduate students imagine a smart alarm clock?

       A.To wake them up on time in the morning.

       B.To earn enough money for their study.

       C.To improve the quality of people's sleep.

       D.To enjoy their life while working at night.

To design the Zeo device, the three graduate students ____.

       A.spent much time and money           B.were widely supported by scientists

       C.worked by themselves all the time       D.attracted many investors

What can we know from the passage?

       A.Zeo has a direct effect on users' lifestyles.

       B.It needs more personal efforts to make Zeo function better.

       C.A large quantity of Zeo devices have been sold in Australia.

       D.Consumers can go to the Zeo company to purchase Zeo in person.

Fermat’s Last Theorem
Simon Singh
In 1963 a schoolboy called Andrew Wiles reading in his school library came across the world’s greatest mathematical problem: Fermat’s Last Theorem (定理). First put forward by the French mathematician Pierre de Fermat in the seventeenth century, the theorem (法则)had baffled and beaten the finest mathematical minds, including a French woman scientist who made a major advance in working out the problem, and who had to dress like a man in order to be able to study at the Ecole
Polytechnique. Through unbelievable determination Andrew Wiles finally worked out the problem in 1995. An unusual story of human effort over three centuries, Fermat’s Last Theorem will delight specialists and general readers alike.

Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit(轨道) of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

    However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse(椭圆形).

    Now Halley set to work. He figured out(解决,计算出)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.

    This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

    It was an astonishing idea! Halley felt certain to make a prediction(预言)of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley’s comet, in his honor.

1.Edmund Halley figured out the orbit of ____.

    A. some different comets appearing several times

    B. the same comet appearing at different times

    C. three different comets appearing at the same time

    D. several comets appearing at the same time

2.Halley made his discovery ____.

    A. by doing experiments

    B. by means of his own careful observation

    C. by using the working of other scientists

    D. by chance

3.Halley made a surprising, but correct prediction in the year____.

    A. 1704     B. 1705     C. 1706     D. 1707

4.This passage in general is about ____.

    A. Halley and other scientists

    B. the orbit of a comet

    C. Newton and Halley

    D. Halley and his discovery

5. Which of the following is TRUE?

    A. Edmund Halley was an American scientist.

    B. Halley made his discovery by doing experiments.

    C. Isaac Newton was a famous mathematician.

    D. The orbit of a comet had the shape of an around.
