第 21 题 请选择（1）处的最佳答案．

Part B ［A］ Analyzing your own taste

［B］ Being cautious when experimenting

［C］ Finding a model to follow

［D］ Getting the final look absolutely right

［E］ Learning to be realistic

［F］ Making regular conscious choices

When we meet people for the first time, we often make decisions about them based entirely on how they look.

And, of course it’s something that works both ways, for we too are being judged on our appearance.

When we look good, we feel good, which in turn leads to a more confident and self-assured manner. People then pick up on this confidence and respond positively towards us,

Undoubtedly, it's what's inside that's important, but sometimes

we can send out the wrong signals simply by wearing inappropriate clothing or not spending enough time thinking about how others see us.

41___________

For example, people often make the mistake of trying to look like someone else they’ve seen in a magazine, but this is usually a disaster as we all have our own characteristics.

Stand in front of a fulllength mirror and be honest with yourself about what you see.

There is no need to dwell on your faults—we all have good points and bad points—but think instead about the best way to emphasize the good ones.

42___________

When selecting your clothes each day, think about who you’re likely to meet, where you’re going to be spending most of your time and what tasks you are likely to perform. Clearly,

some outfits will be more appropriate to different sorts of activity

and this will dictate your choice to an extent. However, there’s no need to abandon your individual taste completely. After all,

if you dress to please somebody else’s idea of what looks good, you may end up feeling uncomfortable and not quite yourself.

43___________

But to know your own mind, you have to get to know yourself.

What do you truly feel good in? There are probably a few favourite items that you wear a lot—most people wear 20 per cent of their wardrobe 80 per cent of the time.

Look at these clothes and ask yourself what they have in common.

Are they neat and tidy, loose and flowing? Then look at the things hanging in your wardrobe that you don’t wear and ask yourself why.

Go through a few magazines and catalogues and mark the things that catch your eye. Is there a common theme?

44___________

Some colors bring your natural colouring to life and others can give us a washed-out appearance. Try out new colours by all means,

but remember that dressing in bright colours when you really like subtle neutral tones,

or vice versa, will make you feel selfconscious and uncomfortable.

You know deep down where your own taste boundaries lie. And although it’s good to challenge those sometimes with new combinations or shades,

take care not to go too far all at once.

45___________

So, you’ve chosen an outfit that matches your style,

your personality, your shape and your colouring. But does it fit? If something is too tight or too loose,

you won’t achieve the desired effect, and no matter what other qualities it has, it won’t improve your appearance or your confidence. Sometimes,

we buy things without thinking. Some people who dislike shopping grab the first thing they see,

or prefer to use mail-order or the Internet. In all cases, if it doesn’t fit perfectly, don’t buy it, because the finer details are just as important as the overall style.

Reappraising your image isn’t selfish because everyone who comes into contact with you will benefit. You’ll look better and you’ll feel a better person all round. And if in doubt, you only need to read Professor Albert Mehrabian’s book Silent Messages to remind yourself how important outward appearances are.

His research showed that the impact we make on each other depend 55 per cent on how we look and behave,

38 per cent on how we speak and only 7 per cent on what we actually say.

So, whatever stage you are at in your life, whatever role you play, isn’t it time you made the most of yourself?

Virtual Driver

Driving involves sharp eyes and keen ears, analyzing with a brain, and coordination between hands, feet and brain. A man has sharp eyes and keen ears, analyzes through his brain, and maintains coordination between his hands and brains. He can control a fast-moving car with different parts of his body. __________ (46) Apparently there isn&39;t anyone in the driver&39;s cab, but there is in fact a virtual driver. This virtual driver has eyes, brains, hands and feet too. The minicameras on each side of the car are its eyes and are responsible for observing the road conditions ahead of it as well as the traffic to its left and right. If you open the boot, you can see the most important part of the automatic driving system: a built-in computer. __________ (47) The brain of the car is responsible for calculating the speeds objects surrounding the car are moving at,analyzing their position on the road, choosing the right path, and giving orders to the wheel and the control system.<br>

In comparison with the human brain, the virtual driver&39;s best advantage is that it reacts quickly.<br>

__________ (48) However, it takes the world&39;s best racecar driver at least one second to react, and this doesn&39;t include the time he needs to take action.<br>

With its rapid reaction and accurate control, the virtual driver can reduce the accident rate on expressways considerably. In this case, is it possible for us to let it have the wheel at any time and in any place? __________ (49). With its limited ability to recognize things, the car can now only travel on expressways.<br>

The intelligent car determines its direction by the clear lines that mark the lanes clearly and recognizes vehicles according to their regular shapes. __________ (50). This being the case4,people still have high hopes about driverless cars, and think highly intelligent cars are what the cars ture should be like.<
