There are a number of different tricks you can use to try to stay awake, as well as habits you can adopt to help your alertness.

Get a full night's sleep on school nights. The National Sleep Foundation has reported that teenagers may need more sleep than adults.    2    This is a key part to staying awake in class. If you are not tired, you are unlikely to fall asleep.

Eat a healthy breakfast full of nutritious foods.    3    If you get hungry or tired in the middle of the day, try eating a healthy snack like a piece of fruit or some biscuits. If necessary, drink something with sugar or caffeine in it directly before the class.

    4    If you are actively engaged in the information the teacher is presenting, you are less likely to doze off. Taking notes, asking questions and otherwise getting involved in classroom activities anddiscussions will make you far less likely to doze off.

Contact your doctor in order to rule out medical conditions that can cause you to fall asleep.     5    Prescription drugs may also cause sleepiness or drowsiness as a side effect, so discuss any medicines you are taking with your doctor.

A．Get involved during class.

B．Early to bed, early to rise.

C．It can also get you in trouble with your teachers.

D．It can provide you with enough protein to fuel your body.

E．Energy-boosting drinks keep you energized during the time you're in class.

F．If you have a medical condition that is causing you to fall asleep in class, you will need to be treated by a professional.

G．Go to bed earlier and make sure you get as many hours of sleep as your body needs.

Khan Academy is a website providing a free education for any person. The website includes more than 4,000 short teaching videos about many different subjects. Every month, over 7 million people go to the Khan Academy website to watch its videos.

Khan Academy began with one man named Salman Khan. As a young man, Khan got a degree from Harvard Business School and began to work in business.

In 2006, Khan used the Internet to help his young cousins, who lived far away, with their mathematics schoolwork. He drew numbers and pictures on the website to teach them. After a time, he put his videos onto the website YouTube, where his cousins could watch them any time they wanted. But Khan noticed that other people were also watching his videos on YouTube.

By 2009, the number of people watching his videos on YouTube was getting very large. Khan decided to make the videos his job instead. So he officially began Khan Academy, providing videos on mathematics and other school subjects.

People did not have to pay to watch the videos. But they could give Khan money if they wanted to support (支持) his work. Some people did give Khan small amounts of money, but he was still having a hard time. Later, a woman told Khan that Bill Gates uses Khan Academy for his kids. After that, the Bill and Melinda Gates Foundation began giving money to Khan Academy. In 2010 Google gave the website money too, wanting Khan to translate his videos into the world’s most common languages. Today, people can see Khan’s videos in many different languages.

Some people think that Khan Academy will be the way more and more people learn in the future. Teachers can use it in their classrooms. Khan believes that Khan Academy will never, and should never, replace a school. But he believes teachers and students can use it to make schools better.

【推荐2】When we’re in trouble, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions (延伸) of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?

In the past the generation gap included a technology gap, where children were up to date with the latest technology and parents were left behind, content to continue their day-to-day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation (动机) to educate themselves about social networking sites.

These days many people are attracted to social networking sites because they can choose who they have around them, there’s also a certain amount of control over privacy (隐私) that we don’t get in real life. Sometimes we feel that privacy is violated (违背) when we must accept a “friend” request from a parent or family member.

It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “refuse” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.

A recent survey suggested that parents shouldn’t take it personally if their children overlook (忽略) their requests. When a teenager overlooks a parent’s friend request, it doesn’t necessarily mean that he is hiding something, but it could mean that this is one part of his life where he wants to be independent.

Perhaps talking with parents and explaining would help soften the blow if you do choose not to add them to your friend list.

1. What is the passage mainly about?

A．Privacy online.	B．Parents’ friend requests.
C．The generation gap.	D．Social networks.

2. What can we infer from Paragraph 2?

A．Parents have realized the importance of social networks.

B．Parents feel secure about their privacy online.

C．Social networks successfully fill the generation gap.

D．Social networks offer a chance for parents to communicate.

3. What maybe the reason for teenagers to refuse a parent’s friend request?

A．Their parents make negative comments on them.

B．They hide something from their parents.

C．They are unwilling to be watched by parents.

D．Their parents tend to fall behind in technology.

4. What does the underlined “that” in Paragraph 4 refer to?

A．Online lives.	B．The difficult choice.
C．Parents’ request.	D．Teenagers’ refusal.

【推荐3】Would you give your Social Security (安全) Number to the worker at the supermarket? Of course not, right? Yet, if you're like most people, you wouldn't hesitate to give out a different, but equally important number to the same person.

Experts now say that your cellphone number may be more pivotal than any other personal information in the eyes of spammers(垃圾邮件发送者) and identity thieves. In other words, you should guard that cellphone number with your life.

Today, your cellphone number will likely be with you for a very long time. That means if spammers get your cellphone number, it will be much harder to get rid of them. It also means that over the years, your cellphone number will be linked to a lot of personal information from contact lists to bank card numbers, all information that hackers would love to get their hands on.

A few years ago, German security researcher Karsten Nohl showed what he could get using only a person's cellphone number. Califomia Congressman(国会议员) Ted Lieu was given a new cellphone for a day and Nohl was given that cellphone number. Using just that number, Nohl was able to find Lieu's location and movements throughout Los Angeles, read his emails and text messages, and record phone calls between Lieu and his team. And Nohl did all of this from his office in Berlin using just a cellphone number.

Still think it's a good idea to post your number on the Internet?

When you sign up for an account(账户)online, you usually provide your email address and a password. But if you forget that password, many of these companies will send you a password retrieval code(检索码)to your cellphone. Let's say you post something for sale online and you include your name, email, and cellphone number. You've now given a potential(潜在的))thief everything he needs to hack into any of your online accounts. Therefore, it just makes sense to protect yourself by guarding that number as closely as you would guard any other personal information.

1. What does the underlined word "pivotal" in Paragraph 2 most probably mean?

A．Accessible	B．Familiar
C．Important	D．Manageable.

2. What does the third paragraph mainly talk about?

A．Why people should protect their cellphone numbers.

A．Nohl is a real expert in hacking.

B．It's necessary to fight against hackers.

C．Lieu's new cellphone has powerful functions.

D．It's easy to hack information through cellphone numbers.

4. What can we infer from the last paragraph?

A．It's a good idea to sell something online.

B．It's necessary to register several accounts online.

【推荐1】The idea of turning recycled plastic bottles into clothing is not new.During the last five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into fabric to deal with plastic pollution.But there's a problem with this method.Research now shows that microfibers could be the biggest source of plastic in the sea.

Dr.Mark Browne in Santa Barbara, California, has been studying plastic pollution and micro-fibers for 10 years now.He explains that every time synthetic (合成的) clothes go into a washing machine, a large number of plastic fibers fall off.Most washing machines can't collect these microfibers.So every time the water gets out of a washing machine, microfibers are entering the sewers and finally end up in the sea.

In 2011, Browne wrote a paper stating that a single piece of synthetic clothing can produce more than l, 900 fibers per wash.Browne collected samples from seawater and freshwater sites around the world, and used a special way to examine each sample.He discovered that every single water sample contained microfibers.

This is bad news for a number of reasons.Plastic can cause harm to sea life when eaten.Studies have also shown that plastic can absorb other pollutants.

Based on this evidence, it may seem surprising that companies and organizations have chosen to turn plastic waste into clothing as an environmental “solution”.Even though the science has been around for a while, Browne explains that he's had a difficult time getting companies to listen.When he asked well-known clothing companies to support Benign by Design—his research project that seeks to get clothes that have a bad effect on humans and the environment out of the market, Browne didn't get a satisfying answer.Only one women's clothing company, Eileen Fisher, offered Browne funding.

【推荐2】It might sound unbelievable, but the mind control television could soon become a reality. This technology could one day replace the remote control.

　   When testing the prototype, the users were able to operate a headset that allowed them to operate it and choose what they wanted to watch by concentrating. The device can know what you want to watch by reading the changes in brain activity. Cyrus Saihan, head of Business Development at BBC Digital, said the technology was still at an experimental stage.
　　Writing in a BBC blog, he said an experiment with ten members found they could all use the headset to start watching a program. He continued, “You can imagine a world where instead of having to get up from your sofa or reach for your remote control, you just think ‘put BBC 1 on’ when you want to watch TV. Imagine sitting in your car and thinking ‘I want to listen to Radio 4’ and hearing the radio station come on. Perhaps you would be able to just think ‘give me the latest news’, and then get served with a set of news.”
　　But Mr. Saihan added, “It’s important to know that it’s very early days, and while the devices are still improving, what they can do is still quite basic. Hopefully, it gives an idea of how audiences of the future might be able to control devices such as TVs just using their brain.” It is hoped that the system could be used to help those with disabilities in the future.
1. What do we know about the mind control television from the text?

A．It is still at the test stage.	B．It is just in people’s mind.

【推荐2】Two-year-old Samantha Savitz is deaf and loves interacting with her neighbors, so they all learned sign language in order to communicate with her better. The little girl is just so charming and adorable that it’s hard not to want to be able to have simple conversations with her.

In the United States，about two to four of every 1,000 people are functionally deaf—about 2 million people. Around 28 million Americans, 10% of the population，have some degree of hearing loss. Around 500, 000 deaf people in the country use American Sign Language (ASL), and it's the third most commonly used language in the US; many hearing people are also fluent in ASL. With so many people using ASL, it's only right that Savitz's neighbors learn the language，not only for her but also to be able to communicate with other deaf people.

Located at the end of Islington Road in Newton, Massachusells, this little neighborhood is absolutely charmed by one little girl. Savitz is a super engaging girl, and she loves interacting with people in her community. She is delighted when they are able to sign with her. However, she gets really sad when they can't understand her when she tries to communicate with them. Because of this, Savitz's neighbors collectively hired an instructor for ASL classes. With the help of their instructor, Rhys McGovern, the neighbors are able to help Savitz feel a sense of belonging.

What the neighbors did for this little girl is wonderful because she will grow up being well-adjusted in society .Instead of feeling separated because no one outside of her family will understand her, Savitz will be accustomed to constantly interacting with different people. Her family is so thankful that they are fortunate to have such caring and compassionate neighbors. Savitz calls her neighbors “friends,” and accurately so.

Other than speaking with the darling of their neighborhood, the residents of Islington Road will also be able to communicate with any other deaf person they encounter. “We are really enjoying the whole process，not only the learning of ASL, but the learning together,” says McNeil, one of Savitz’s neighbors. “It's made our neighborhood a closer place.”

1. Why does the author present the figures in paragraph 2?

【推荐3】Obviously television has both advantages and disadvantages.

In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don’t have to pay for expensive seats at the theatre, the cinema, or the opera .All they have to do is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if the has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort in his part.

Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one’s sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it, so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and the they have actually begin to talk to each other again. It makes one think, doesn’t it?
