After a day of work and play, the body needs, to rest．Sleep is necessary for good health．During this time, the body recovers from the activities of the previous day．The rest that you get while sleeping enables your body to prepare itself for the next day．

　　There are four levels of sleep, each being a little deeper than the one before．As you sleep, your muscles relax (肌肉放松) little by little．Your heart beats more slowly, and your brain slows down．After you reach the fourth level, your body shifts back and forth from one level of sleep to the others．

　　Although your mind slows down, from time to time you will dream．Scientists who study sleep state that when dreaming starts, your eyeballs begin to move quickly (although your eyelids are closed)．This stage of sleep is called REM, which stands for rapid eye movement．

　　If you have trouble falling asleep, some people recommend (推荐) breathing very slowly and very deeply．Other people believe that drinking warm milk will help make you drowsy．There is also an old suggestion that counting sheep should put you to sleep．

       Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about drinking is the key to critical（判断性的）thinking. When you think critically, you take control of your thinking processes（过程）. Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.

       The word “critical” here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen-beyond the pictures on TV, the untrue reports in the newspapers, and the faulty reasoning.

       Critical thinking is an attitude as much as an activity. If you are curious about life and desire to dig deeper into it, you are a critical thinker. If you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker.

       Activities of the mind and higher-order reasoning are processes of deep and careful consideration. They take time, and do not go hand in hand with the fast speed in today’s world: fast foods, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure of intelligence（智力）, you may learn something new from a story about Albert Einstein. The first time Banesh Hoffman, a scientist, was to discuss his work with Albert Einstein. Hoffman was too nervous to speak. But Einstein immediately put Hoffman at ease by saying, “Please go slowly. I don’t understand things quickly.”

72．Critical thinking is important to us because if we do not think critically, _______.

       A．it will be hard for us to think naturally and fast

       B．we might be controlled by other people’s ideas

       C．we will follow the ideas of others naturally

       D．we might be footed by other people’s ideas

73．If you are a critical thinker, you will ________.

       A．think deeply about different ideas   B．trust the reports in the newspapers

       C．take one view against another view D．criticize other people for their mistakes

74．In the last paragraph, “something new” suggests that ________.

       A．the smarter you are, the faster you do things

B．the faster you do things, the smarter you become

C．speed can improve intelligence

D．intelligence is not decided by speed

75．What would be the best title for the passage?

       A．Thinking and Critical Thinking.     B．Understanding Critical Thinking.

       C．Thinking Is Natural and Human.    D．Thinking Fast Means Intelligence.
