The problem is hard to solve. __________.

A．Don't be late                                     B．Have a seat    

C．Use your brain                                    D．Give him the paper

A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸张), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (开夜车). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.
Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.
【小题1】What does the underlined sentence “it’s close to the truth” mean?

Learn to relax. Overwork is the main reason why so many students feel tired. Cut down some of the jobs you need to do each day so that you only do the most important things well. Leave time for activities that are relaxing and fun. This might mean reading a good book, listening to the music, going for a walk or taking a relaxing bath. You will feel very good.
Get a good night’s sleep. Getting enough sleep will help you keep your body and mind﹡ in the best form﹡. If you stay up late and need to get up early for school the next day, you may not be able to pay attention﹡ to the things you need to do. You also feel tired.
Exercise regularly and eat well. Don’t rush through your meals. Eat less junk food or fast food. Eat healthy food instead. Fruits and vegetables are necessary.
Get to know pleasant people. Some people are optimistic, while others are not. Choose optimistic people as your friends and spend more time with them and you’ll be as happy as them. You’ll see everything with the optimism.
Learn to be calm when you face any problem. Find out the best option from those that are in your mind. Knowing that you are able to solve problems is a good way to build up your self-confidence﹡. 
Be happy. How you feel decides the way you see things. Is your cup half full or half empty: Learn to think more positively﹡ about the difficulties you face.
【小题1】This passage mainly talks about _________.

Tony Buzan’s grades were going down at university. Disappointed with his low marks, he went to the library to find a book on how to use his brain. He was directed to the medical section. Confused, he said to the librarian, “I don’t want to take my brain out, I just want to learn how to use it.” Her reply was simple: “There’s no book on that.”

“I thought to myself,” says Buzan, “if I buy a little radio, I get an instruction manual (说明书). If I buy a microwave, I get an instruction manual. But for the most important machine in the world, no instruction manual?”

Fifty years later, Buzan has become the world’s leading speaker on the brain and learning. In the late 1960s, he invented the mind map, a visual representation of thought processes.

This kind of thinking has become a popular tool for planning, organizing, problem solving, and communicating across the world. He has since authored and co-authored over 100 books that have appeared in more than 30 languages.

“I think in most cases, people use less than 1 percent of their brains,” he says.

But how do you expand this 1 percent? How do you become the best student you can be?

According to Buzan, the answer is simple. You take a section of whatever it is that you are trying to learn, he says, and you read it for its essence (精髓、要素). Then you make a mind map of all the important details. For a truly effective mind map, you start with a colored image in the center of your page. Draw the first image that comes to mind on the topic you are mind mapping. Branch off from your central image and create one of your main ideas. From your main branches draw some sub-branches and from those sub-branches you can draw even more branches. He emphasizes that you should use plenty of images and colors as these help with memory recall and encourage creativity.

By using this visual format (形式), according to Buzan, your mind will begin to make associations that will help you remember more information for longer periods of time.

Buzan believes that traditional note-taking methods, such as lists and summaries, do not stimulate the brain’s recall capacity or ability in the same way. Because of this, students will often find themselves locked away in their rooms for hours, trying hard to memorize separate details. Buzan believes that for a more effective and lasting way of studying, you must first understand how your brain works.

“Everyone is born smart,” he says. “You just have to learn how to learn.”
