How the Body Keeps the Same Temperature
The temperature of your body should be always just the same, no matter whether the weather is hot or cold. That is why the doctor uses his thermometer when you are sick. When you are well, your temperature is ninety-eight and six tenths degrees. If he finds it(51) than that, it is a sure sign that something is wrong.
The body keeps the same temperature all the time, because it balances (平衡) the heat it produces and(52) off. It is always burning up food and producing heat. It can produce heat faster when it needs to or give off heat faster when it becomes too warm. Let's see(53) this happens.
The heat of your body is given off chiefly through the skin. When you are(54), your skin is tight and shows "goose flesh". When you get chilly (寒冷的),you must dance around to keep warm or(55) you will shiver (颤抖).(56) your muscles begin to work, burn up fuel, and produce more heat. It is not(57) to shiver, so you usually prefer warming up by exercise, or put(58) more clothes to keep heat in.
When you are warm, the skin is loose and soft. It is so supplied(59) blood that heat is given off rapidly. If you get too hot, you begin to sweat, and(60) body heat is used in evaporating (蒸发) the moisture (潮湿) from your skin. You wear less clothing, too, in warm(61) or in a warm room, so that warmth can be given off freely. You feel you don't(62) exercising because your body is warm(63),and the extra heat produced by exercise makes you uncomfortable.
You can see from this why you(64) differently in different kinds of weather. In summer, when it is warm, you feel tired and lazy. You do not care to work or play, but enjoy lying and doing nothing. When you get out of doors in winter, the cold air makes you feel(65) You want to run and play.
A．taller
B．better
C．superior
D．higher

Another example of the world appearing to slow down is when you are hanging on the phone waiting for someone to pick up at the other end. If your attention wanders while you're waiting, then suddenly switches back,you will probably hear what seems like a longer than usual silence before hearing the dialling tone again. For you, time will have momentarily slowed.
To see how our perception of time changes when something new happens, Vincent Walsh and his colleagues put headphones on volunteers and played eight beeps to their right ears. The gap between each beep was exactly i second, except for the gap between the fourth and fifth beeps, which the scientists could make shorter or longer. They altered the length of this gap until the volunteers estimated it was the same length as the other gaps. The researchers found that, on average, people judge a second slightly short, at 955 milliseconds.
In the second part of the experiment, the first four beeps were played to the subjects' right ear, but the other four were then played to their left. Again, the volunteers were asked to estimate when the gap between the fourth and fifth beeps was the same as the others. This time they judged a second to be even shorter at 825 milliseconds long.
Perceiving a second to be much shorter than it is makes you feel as though the world has gone into slow motion, since less happens in that slice of time. Walsh thinks the effect could have evolved to give us a fraction more time to react to potentially threatening events.
Last year, Kielan Yarrow, a British psychologist found a similar effect with vision. When you glance at a clock, the first second will seem longer than it really is.
Yarrow's results showed that time appeared to slow down by a similar amount as Walsh found. Previous studies have shown that cooling the body slows down our perception of time while warming it up has the opposite effect.

A．the world around you had slowed down

Computers in Cars
You ’re far from home 0n a lonely road．Shadowy forests stretch away 0n both sides．A thick mist （雾）makes it difficult to see far beyond your car’s windshield（挡风玻璃）．
“Can this be route 90A？ ” you wonder． If it is，you should be near a town． Yet there’s no hint of one． Night is closing in． and you’re low on gaso1ine．
This is a situation where an in-car computer that can navigate Would be a big help．
A car computer that navigates？ Yes! Such computers exists． Several experimental models are being tested by General Motors，Ford，Chrysler，and several foreign car markets．These computers vary in details． But they a11 contain series 0f maps on Vediodiscs or videotapes． For example，one computer system contains 1 3，300 maps covering the Continental US．
Before starting out 0n a trip，a driver can type in the code for the region he 0r she plans to drive though．The computer then shows a map 0f that region． At the same time， a tiny radio receiver linked to the computer goes to work． It picks up signals from navigation satellites such as the NAVSTAR network． Using these signals， the computer shows a the car’s position at all times and displays this position on the map． The computer can also calculate and display the best route to follow．
A navigation computer may also receive and use data about road construction． weather conditions，and traffic jams． This information would be displayed to the driver and the computer would also use the information to work out alternate（交替的）routes．
Most ears nowadays also contain computers that help cars run more efficiently． Microprocessors （微处理机的）Control certain engine functions by regulating the mixing of fuel．Data on car speed， oil pressure，revolutions per minute， engine temperature， and fuel level can be displayed as digital data（numbers）or warming lights．
Some auto designers suggest that a central computer display can he used to clearly present such timely information as ear speed and fuel level． Warning 1ights would indicate a drop in oil pressure or a sudden rise in engine temperature． To get more information 0n these conditions， the driver would call it up on the computer display screen． When needed，the computer could he “asked” to provide navigation aid or information about the car’s Condition．
第 6 题 By describing a typical situation of a lost driver on the road，the author intend to
A．make us believe how complex the highway computer network is．
B．let us know how in-ca computers are linked to road signs
C．show us how helpful a navigation computer would be
D．tell us that NAVSTAR has collie into use．
