There is a lot of misunderstanding about studying. Most students have not been taught the principles behind really effective working. Imagine a graph showing the amount a person learns against the number of hours he works in a day. If he doesn’t do any work, he learns nothing (point 0). If he does an hour’s work he learns a certain amount (point 1). If he does two hours’ work he learns about twice as much (point 2). If he does more work he’ll learn still more (point 3). However, if he tries to do twenty-three and a half hours’ work in a day, he will be so tired that he’ll hardly remember anything: what he learns will be very little (point 4). If he did less work he’d learn more (point 5).

Now whatever the exact shape of the graph’s curve(曲线), made by joining these points, it must have a high point. Point “X” is the very maximum anyone can learn in the day. And this represents the optimum(最适度), the best, amount of work to do. It is the best possible compromise between adequate time at the books and fatigue(劳累). Fatigue is an absolutely real thing; one can’t escape it or ignore it. If you try to ignore it and press yourself to work past the optimum, you will only get on this downward slope and achieve less than the best – and then become very tired and lose your power of concentration.

The skill in being a student consists of getting one’s daily study as near the optimum point as possible. I cannot tell you what the optimum is. It differs with the type of work, it differs from person to person, and even in the same person it varies from week to week. You must try to find your own. Every day you study, bear this principle of the optimum in mind. When you feel yourself getting fatigued, if you find yourself reading the same paragraph over and over again and not taking it in, that’s a pretty good sign you’ve reached your highest point for the day and should stop. Most ordinary students find their optimum at five hours a day. Yours may be a little more or a little less – but if you get in five hours’ good work a day, you will be doing well.

Now, what are you doing with yourself when you aren’t working? Before examinations some students do nothing at all except sit in a chair and worry. Here is another misunderstanding. People often think that the mind works like the body; it does not. If one wanted to save one’s physical energy in order to cut the maximum amount of firewood, one would lie flat on a bed and rest when one wasn’t chopping. But the mind cannot rest. Even in sleep you dream, even if you forget your dreams. The mind is always turning. It gets its relaxation only by variety. That is what makes the mind rest.

When you’ve finished your optimum number of hours you must stop. You must not then sit around in the chair thinking about the work – that only tires without any learning. You must get out and do something. It doesn’t matter what – anything so long as you are actively doing something else but work.

Basic Math introduces students to the basic things of mathematics, as well as some easy methods of learning it. These 30 fantastic courses are designed to provide students with understanding of arithmetic and to prepare them for Algebra (代数) and beyond.
　　The lessons in Basic Math cover every basic field of arithmetic. They also look into exponents (指数), the order of operations, and square roots. In addition to that, students also discover how a particular mathematical topic relates to other branches , and how they can be used practically.
　　Basic Math starts from easier concepts and gradually moves on to the more troublesome ones.  The lectures offer students the chance to understand of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and develop confidence in this amazing field of study.
　　With the help of these lectures, they will be able to clear away the mystery (神秘性) of mathematics and face their studies with more confidence than they ever imagined. Besides, they will strengthen their ability to accept new and exciting mathematical challenges.
　　Professor H. Siegel, honored by Kentucky Educational Television as "the best math teacher in America, " is a devoted teacher and has a gift for explaining mathematical concepts in clear and interesting ways. From the basic ideas to the more difficult problems, he is a master in making math lectures learner-friendlier and less frightening
　　With a PhD in Mathematics Education form Georgia State University, Dr. Siegel now teaches mathematics at Central Arizona College.
　　If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer. Or you can get your money back.
【小题1】What does the course Basic Math mainly cover?

This is no joke. Kelly Katrina Hildebrandt, 20, and Kelly Carl Hildebrandt, 24, are expecting just over 100 guests at a(an)   21  at a church, where they will become husband and wife.
Their modern romance was a   22  made in cyberspace（网络空间）. She was   23  and bored one night last year, so she typed her name into the   24  social networking Website Facebook just to see if anyone   25  it: Hildebrandt, 24, in South Florida. At the time, Kelly Hildebrandt, of Lubbock, Texas, was the only one matched. So she sent him a   26 . She said, “Hi. We had the same name. Thought it was cool.” Kelly Carl Hildebrandt said, “I thought she was pretty   27 .”
For the next three months the two   28  e-mails.   29  he knew it, occasional phone calls turned into daily chats, sometimes   30  hours. He   31  her in Florida after a few months and fell head over heels.
“I thought it was fun,” he said of that first online meet. “I had no   32  that it would lead to this.”
Months after Kelly Hildebrandt sent her first e-mail, she found a diamond engagement   33   hidden in treasure box on a beach in December. “I totally think that it’s all God’s   34  ,” Kelly Katrina Hildebrandt said. “He planned it out just   35   .”
She's a student at a local community college. He works in financial   36 . They plan to make their home in South Florida.
There was also some uncertainty   37  how to phrase their wedding invitations, so they decided to include their   38  names. But   39  confusion likely won't carry on past the husband and wife, as Kelly Katrina Hildebrandt said there are no plans to pass along the name to their future   40 . “No,” she said. “We're definitely not going to name our kids Kelly.”
