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 （有回復(fù)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 （傳感器） 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．a(chǎn)ttracted 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．

Some people will do just about anything to save money. And I am one of them. Take my family’s last vacation. It was my six-year-old son’s winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meeting in New York，So I had to get back . But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

The next day my husband and son were offered more credits to take an even later flight. Yes, I encouraged一okay, ordered-them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?

If you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault.
Have you ever found that some people can't read or write but they have better memories? This is because they cannot read or write and they have to remember things; they cannot write them down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised.
So if you want to have a good memory, learn from the people: practise remembering.

Bored by the Chinese courses he was majoring in, Zuo Cheng, 18, couldn't imagine having to drag himself into class day after day, week after week, for four years．

The Beijing Language and Culture University student decided that enough was enough．

61  

"It may seem like I've wasted a year and have to start college all over again, but now that I've settled on a field I'll be able to concentrate．" Zuo said．

Zuo is not alone．

At the China Three．Gorges University in Yicljang in Hubei Province 53 out of 59 students in the Physics Department took transfer exams last semester．  62  

"   63   Many students picked colleges before majors, only to discover their mistakes a few weeks after arrival on the campus．" said Jiang Xin, 20, who was able to switch to electrical engineering and automation from physics．He said that physics graduates had few other options besides going into teaching,     64  

A new survey, of 2,500 students nationwide starting in September this year, suggests that as much as 35 percent of students are disappointed by their courses．

However, Shao Yangfang, who works at the admission office of University of International Business and Economics in Beijing, advised students to consider both short-term and long-term goals．

"After graduation do you want to find yourself in a job very specially related to your college major? Or, would you like to possess the knowledge and skills that will enable you to work in many areas?    65    Above all, your choice of major should be based on your own interest, abilities and personality．" Shao said．

A．These are the questions students need to consider．

B．After rounds of exams and interviews, he managed to transfer to the Department of International Accounting．

C．He added that a career in education just didn't suit him．

D．Unfortunately only 22 of them got a place on another major．

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中，選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

If you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows this, and nobody would think of questioning this fact. 1. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly, either consciously or unconsciously. When someone else says that his memory is poor, he really means that he does not give it enough opportunity to become strong. 2.  . One of them exercises his arms and legs by playing tennis, while the other sits in a chair or a motor car all day.

If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is just as much his own fault as if it was his arms or legs that were weak.  3.. But all of us can, if we have ordinary bodies and brains, improve our strength and our memory by the same means — practice.

Have you ever noticed that people who cannot read or write usually have better memories than those who can? 4.. Of course, because those who cannot read or write have to remember things. They cannot write them down in a little notebook and they have to remember dates, time and prices, names, songs and stories, so their memory is the whole time being exercised.

 5.  .

A. What do you think of it?

B. Yet many people do not seem to know that the memory works in the same way.

C. Not all of us can become extremely strong or extremely clever.

D. So if you want a good memory, practice remembering.

E. Someone else says that he is poor in health.

F. Why is this?

G. The position is exactly the same as that of two people
