Most teens need about 8 to more than 9 hours of sleep each night．The right amount of sleep is necessary for anyone who wants to do well in a test or play sports without tripping over their feet. Unfortunately，though，many teens don’t get enough sleep.

_______________? Early starting time in some schools may play a role in this sleep deficit (不足)．Teens who fall asleep after midnight may still have to get up early for school，meaning that they may only shorten into 6 or 7 hours of sleep a night．A couple of hours of missed sleep a night may not seem like a big deal，but can create a noticeable sleep deficit over time.

Why is sleep important? Sleep deficit affects everything from a person’s ability to pay attention in class to his or her mood．Research shows that more than 20% of high school students fall asleep in class，and experts have been able to tie lost sleep to poorer grades．Lack of sleep also damages teens’ ability to do their best in sports．Slowed responses and less concentration(專注)caused by sleep deficit don’t just affect school or sports performance，though．Lack of sleep slows reaction time，which can be life threatening for people who drive．The National Highway Safety Traffic Administration reports that 1，500 people are killed every year in crashes caused by drivers between the ages of 15 and 24 who are simply tired．Lack of sleep has also been linked to emotional troubles， such as feelings of sadness and depression．Sleep helps keep us physically healthy，too，by slowing our body’s systems enough to re-energize us after everyday activities.

How do I know if I’m getting enough sleep? Even if you think you’re getting enough sleep， you may not be．Here are some of the signs that you may need more sleep: (1) difficulty in waking up in the morning；(2) inability to focus；(3) falling asleep during classes； (4) feelings of anxiety and even depression(憂郁)．Recently，some researchers，parents，and teachers have suggested that middle and high school classes begin later in the morning to meet teens’ need for more sleep．Some schools have already tried later starting time．You and your friends，parents，and teachers can call up for later start time at your school，but in the meantime you’ll have to make changes on your own first.

Scientist Stephen Hawking had to work really hard to speak．He chose letters and words from a screen controlled by movements of a muscle in his cheek．However，the slow system he used might soon be replaced．With a very different approach，doctors have found a way to get a person’s speech directly from their brain.

The system uses brain-reading software．It works only for sentences it has been trained on. Doctors at the University of California in San Francisco (UCSF) set out to create a better product， which allows people who are paralyzed (癱瘓的) to communicate more quickly than Hawking’s device，which uses muscle twitches(抽搐)to control a keyboard.

The Study of Brain Activity

The work was possible thanks to three patients．They had epilepsy(癲癇癥)．This is a condition that has something to do with the nerves．It causes seizures(痙攣)．This is when their body suddenly moves on its own．They were about to have surgery(外科手術(shù))for their condition.

Before their surgery，they had a small device placed on their brain for at least a week．It was used to map their seizures.The patients could speak normally，and they agreed to take part in Doctor Chang’s study．The doctor used the devices to record brain activity while each patient was asked nine questions．The patients were also asked to read a list of 24 possible responses.

Using the recordings，Chang and his team built computer models．The models learned to match patterns of brain activity to the questions the patients heard and the answers they spoke．Once trained，the software could identify questions and responses almost instantly．It used only brain signals．It was correct on what question a patient heard 7 out of 10 times．The software identified what response they gave 6 out of 10 times.

Improving Software to Read More Varied Speech

Even with the breakthrough，there are hurdles ahead．One challenge is to improve the software so it can translate brain signals into a variety of speech．This will require software trained on a huge amount of spoken language and matching brain signals．These signals will be different from one person to another.

Another goal is to read “imagined speech”，or sentences spoken in the mind．The system in the study detects brain signals that are sent to move the mouth．However，for some patients these signals may not be enough．More advanced ways of reading sentences in the brain will be needed.

1.From the passage，we can learn that ______.

A.the three patients with epilepsy have difficulty in speaking

B.Stephen Hawking’s system is controlled by his brain signals

C.the patients chose from nine responses to answer 24 questions

D.the brain-reading software can only recognize a few sentences now

2.What does the word hurdles in paragraph 6 mean?

A.Risks． B.Difficulties.

C.Possibilities． D.Disadvantages.

3.The purpose of the last two paragraphs is to _______.

A.tell us the disadvantages of the software

B.present the possible future of the software

C.explain the process of designing the software

D.show the author’s opinion toward the software

4.What’s the main idea of the passage?

A.Different devices to help paralyzed people to communicate.

B.Different ways to develop software that can help paralyzed people.

C.Doctors have started to explore software to read people’s brain signals.

D.The study showed the system could translate brain signals into a variety of speech.

Do you know we are living in the world of mass media? Mass media are tools of communication and allow us to record and pass information rapidly to a large，scattered audience.

However，have you imagined what life would be without the media? Are you a media addict who would go mad after two hours without TV，friend requests，exciting online games and your mobile—or would you easily survive?

Recently，university students around the world were asked to volunteer in a global experiment called Unplugged．It was designed to see how young people would react if they were asked to observe a total media ban(禁止)by unplugging all forms of media devices for 24 hours.

Unplugged is being run by Dr. Roman Gerodimos，a lecturer in Communication and Journalism at Bournemouth University．The experiment is now over but he doesn’t yet know the full findings. However，during the experiment，Dr. Gerodimos said there were already signs of how much the exercise affected volunteers．He said: “They’re reporting withdrawal(孤僻)symptoms，overeating， feeling nervous，isolated and disconnected.”

During their 24-hour ordeal，three volunteers had to endure one intrusion from the media: a BBC reporter plus cameraman who followed them around for the day．They were asked to write down 100 lines about their day offline，but of course，they all waited until the next day when they had access to their laptops.

Elliot Day wrote: “Today，my whole morning routine was thrown up into the air．Despite being aware of the social importance of the media，I was surprised by how empty my life felt without the radio or newspapers.”

From Caroline Scott，we read: “I didn’t expect it，but being taken away from the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual… I didn’t break out in a cold sweat like Dr. Roman Gerodimos expected us all to，but it’s not something I would like to do again!”

And Charlotte Gay wrote: “I have to say the most difficult item for me to be without has been my mobile； not only is it a social gadget，it’s my main access point of communication.”

Earlier in the year，a UK government study found that in the UK we spend about half our waking hours using the media，often plugged into several things at once．And a recent study by Nielson found that on average，US teenagers send and receive over 3，000 texts per month—that’s about six texts per waking hour.

So，with technology continuing to develop at an alarming rate，how much time will you set aside for sleep in the future?

1.According to the passage，what do you learn about the global experiment called Unplugged?

A.The experiment was carried out by US and UK governments.

B.The volunteers of the experiment are all university students.

C.It has been carried out in more than 10 countries for 24 hours.

D.Its findings proved that Dr. Gerodimos’ expectations were true.

2.According to what the three volunteers wrote during the experiment，we can learn that ______.

A.they all feel very surprised and worried

B.all of them feel empty without a mobile

C.it is hard for them to spend the 24 hours without media

D.it makes them realize the social importance of mobile

3.What does the writer think about the mass media?

A.He prefers not to live with it． B.He thinks highly of it.

C.He worries about its influence． D.He is not sure about it.

4.The underlined expression “break out in a cold sweat” probably means _______.

A.losing temper and feeling very angry

B.feeling cold due to sweating a lot

C.feeling empty and wanting to escape

D.sweating because one is nervous

5.What can be the best title of the passage?

A.Hello，technology! B.The young’s lives，a mess?

C.Welcome，information age! D.Mass media，a lifelong partner?

In the United States, most cities have public libraries. Inside most libraries are hundreds of books－and sometimes more!－many of which are available for taking home. Of course, you have to bring any book you borrow back to the library when you're done.

Libraries help people find information. As the ways people find information change, libraries need to change, too. The Internet is a tool that helps people find information much faster than if they were to look in books, so a lot of libraries have begun using computers and technology to help people keep learning.

The New York Public Library is the most famous library in New York City. When the main branch was opened in 1911, it had a collection of over one million books. Outside this main building, two giant stone lions guard the entrance. Since the library is over one hundred years old, bringing in new technology is not easy.

The New York Public Library now has computers in every building. You can use the computers to go on the Internet or to write a paper. The librarians will help if you have a question and there are even free classes to help people learn how to use new computer programs. But this is only the beginning of how the library wants to use technology.

In the basement of the library, there is a room filled with computer programmers and designers who are bringing new technology to the library. This place is called the NYPL Labs. Ben Vershbow runs the NYPL Labs. He wants to help the library reach more people. Ben runs projects using "crowdsourcing."

"Crowdsourcing" means getting a lot of people involved to help with a project. Ben is currently using the Internet to find people to help with the library's collection of menus. The library has thousands and thousands of old menus. You can see what people ate in the year 1900 and find out how much that food cost.

In the past, only people in New York could use the New York Public Library. Now, the library is online and everyone can enjoy it. Thanks to technology, we have a new kind of library.

1.What do libraries help people find?

2.Which library is the most famous library in the New York City?

3.Why does Ben Vershbow run the NYPL Labs?

4.What can we find with the old menus in the New York Public Library?

5.What does the passage mainly talk about?
