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(曲線), 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(最適度), the best, amount of work to do. It is the best possible compromise between adequate time at the books and fatigue(勞累). 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.
【小題1】According to the passage, _______.

A．the longer you study every day, the more you will learn
B．you’ll achieve better learning results if you work three hours every day
C．the less work you do, the better you will learn
D．your work efficiency will decrease once you exceed a certain point of work
【小題2】Fatigue can result in ________.
A．loss of memoryB．a(chǎn) need for relaxation
C．a(chǎn) lot of anxietyD．loss of concentration
【小題3】The passage tells us that a person’s optimum number of working hours _______.
A．follows a regular pattern with each individual
B．changes regularly from week to week
C．can be partly determined by the sort of work he is doing
D．should be determined before he gets too tired
【小題4】The only way the mind can relax is by ________.
A．doing a variety of things in turn
B．not thinking about anything
C．turning continuously
D．getting oneself in a state of fatigue
【小題5】After you have reached the optimum point of study in a day, you should ________.
A．lie in bed and rest
B．do something else actively
C．do some physical labor
D．stop thinking about your studies

科目：高中英語(yǔ) 來(lái)源：2015屆山西省高一12月月考英語(yǔ)試卷（解析版） 題型：閱讀理解

We’re surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher does a big experiment in class. At other times, it can be pretty hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.

Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗滌劑) to water involves chemistry. Without chemistry, we would never have known that we need soap to get the oil out of clothes or skin. Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧層) is and how it protects us. Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白劑) can’t be mixed with vinegar(醋), because it can produce poisonous gas.Without chemistry, we wouldn’t have fireworks displays on important days.

Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw food. Baking is a great example of chemistry. Too much or too little of any ingredient（成分，尤指烹飪） makes a difference to the result of baking, for example, the dough (面團(tuán)) won’t rise or the cake will be flat.

Chemistry isn’t something that just lives in a lab; it’s something that you meet hundreds of times every day. Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest-looking things.

1.What’s the main idea of Paragraph 1?

A．Chemistry is easy to see around us.

B．Sometimes chemistry is hard to see around us.

C．How a science teacher does a big experiment.

D．Few things in everyday life contain chemistry.

2.The following actions are about chemistry EXCEPT _____.

A．cleaning teeth with toothpaste

B．washing hair with hair products

C．using soap to get the oil out of clothes

D．washing your face with water

3.The underlined word “poisonous” in Paragraph 3 means _____.

A．harmful           B．healthy           C．fresh             D．pleasant

4.Which one is TRUE according to Paragraph 4?

A．One can’t find chemistry when cooking food.

B．Chemistry plays an important part in food mak-ing.

C．That dough rises is nothing to do with chemistry.

D．A flat cake is the result of too many ingredients.

5.Which of the following would be the best title for the text?

A．Chemistry Around the House

B．Chemistry in Science

C．Chemistry for Dinner

D．Chemistry in everyday life
