Though times have changed, falling asleep in class is still quite common among teenagers.

Why do students sometimes fall asleep in class? An obvious(显而易见的) reason is lack(缺少) of sleep. However, there are also causes for getting too little sleep.

Homework is a daily meal for most students, one that can take three to four hours per night. A teenager who wants to be able to take part in any activity besides homework must stay up late to fit everything in. Club activities, sports, computer-game playing, and TV viewing, for example, all lead to teens having less time for both homework and sleep. Sometimes teens lack sleep because of after-school jobs that are taken on to earn extra money for college, family cost, or simply for clothes.

Physical problems are another reason that can cause students to fall asleep in class. For example, insomnia(失眠), which may keep a student up at night, causing exhaustion(疲惫不堪) during class hours, is a serious problem that may require medical attention. Medical research also supports the idea that each person has a body clock that helps to decide his or her sleep pattern. Unluckily, these body clocks do not always work according to school timetables.

The effects of falling asleep in class can be quite serious. First of all, sleeping in class is not a good way to show your respect to teachers. In addition, it is highly possible that other students may make jokes about those who sleep in class. However, the most harmful effect of sleeping in class is missing important points. In the long run, sleepers may end up with failing classes.

Since teens are probably not going to deal with the problem, falling asleep in class will probably remain an all-too-common situation. It will continue until more teens find a way to balance their personal and social lives with school and work, while still finding enough time to sleep.

Everybody hates that feeling when you spend three weeks reading a book, and a month later somebody asks you about it and you can’t remember a thing you read. It makes you wonder why you wasted a couple of hours on the words that didn’t stick.

There are some effective ways to learn. And when I say “to learn effectively”, what I mean is to not just build up knowledge, but to be able to apply(应用)that knowledge effectively at some point in the future. By this definition, most of the courses people spend money on is not learning. Something is not truly learned until it changes you in some way.

1. Memory is based on relevance (相关性)

One of my favorite online book clubs is Mentor Box. What’s cool about the club is not only do they send you books to read, but they send you study materials related to them. The study materials, instead of being like school, where it asks you to repeat information in the book to help memorize it, are designed to help you apply the lessons to various areas of your life.

That’s because memory works based on relevance. We only remember what our brain has considered important to our own lives. If you don’t find a way to make it relevant to you and your well-being in some way, your brain will conveniently forget it.

You can do this on your own. When you come across something interesting in a book, write down its application or relevance to something in your life—how you can use the idea, how it explains something in your past, how it can help with your problems, etc.

2. Reading does not have to be linear

People believe they have to read everything, line by line, one after another. This is not only not true, but it’s often a waste of time and energy.

When you buy a book, you’re not buying the words, you’re buying the useful ideas. The point of a book is to gather the information that is relevant and important to you, not to finish it or to understand every word. What matters is the principle or key idea. Once you’ve received that principle or idea, there’s no reason to feel obligated to sit there and read the rest.

3.Think critically and ask the right questions

Everything you read should be questioned. You should question the writer’s biases(偏见 ), whether they’re explaining information correctly, whether they’re overlooking something. When reading something I agree with, I’ll ask myself, “Is it possible that this could be wrong?” Everything should be taken with a grain of salt, for the simple reason that almost everything is largely uncertain. And it’s the ability to manage those uncertainties effectively that will determine the depth of your knowledge and understanding, not the ability to memorize a lot of facts and numbers.

A.is a practical method to have good feelings

B.helps you explain and remember difficult words

C.happens when knowledge changes you in some way

A.Read line by line to receive useful ideas.

4.Which of the following would be the best title for the passage?

A.How to Become A Better Learner

B.How to Memorize Things Effectively

C.Ways of Building Relevance in Your Life

D.The importance of Asking the Right Questions

There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need.

The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure.

How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas an expert(专家)in sleep. He says, “Sleep is like a credit card(信用卡). When you sleep less. You are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to ‘pay back’ the hours on your ‘sleep credit card.’”

For those who value work more than sleep, they should listen to what a famous person once said. “Don’t think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more.”
