they see.Chances are you will receive three different answers.Each person sees the same scene, but each perceives(感觉、察觉) something different about it.

Perceiving goes on in our minds.Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket.Another may say that he sees a rush-hour traffic jam at the crossing.The third may tell you that he sees a woman trying to cross the street with four children.For perception is the mind's explanation of what the senses - in this case our eyes - tell us.

Many psychologists today are working to try to decide just how a person experiences or perceives the world around him.Using a scientific method, these psychologists set up experiments in which they can control all of the factors.By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.

nted a cottage 31 a river in the heart of the country 32 the whole family was going to 33 a three-week holiday. There were four of us: me, Mum and Dad, and Mum‟s sister, Auntie June. Oh, and I mustn‟ t forget to 34 Spot, our little dog. I was 35 to go off by myself all day, 36 I promised to be careful and took Spot with me for 37.

One day I was out fishing with Spot when we heard a lot of shouting in the 38 followed by a scream and splash. I was a bit 39 so I called Spot and we both hid 40 a bush where we could see but not be 41 . After a few moments, a straw hat came drifting down the river, followed by an oar, a picnic basket and 42 oar. Then came the rowing boat itself, but it was 43 upside down ! A few seconds later my Dad and Auntie June came running 44 the river bank, both wet 45 . Spot started barking so I came out of hiding and said hello. My Dad got really angry 46 me for not trying to catch the boat as it went past. Luckily, 47 , the boat and both the oars had been caught by an overhanging tree a little further downstream, but not the hat or picnic basket. So I had to let them 48 my sandwiches. Dad and Auntie June both made me 49 not to tell Mum what had happened 50 she would be worried.

be an optimist (乐观者), a leader, and an active person who enjoys life, people and excitement.Do you prefer grays and blues？ Then you are probably quiet, shy and you would rather follow than lead.You tend to be a pessimist.At least, this is what psychologists (心理学家)tell us, and they should know, because they have been seriously study ing the meaning of color preference, as well as the effect that colors have on human beings.They tell us among other facts, that we do not choose our favorite color as we grow up — we are born with our preference.If you happen to love brown, you did so,as soon as you opened your eyes, or at least as soon as you could see clearly.

Color does influence our moods (情绪)― there is no doubt about it.A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress bri ngs warmth and cheer to the saddest winter day.On the other hand, black is depressing.A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area — until it was repainted green.The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

Light and bright colors make people not only happier but also more active.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or gray.

1.The author regards the psychologists'findings as ().

A.groundless

B.doubtful

C.reasonable

D.unusual

2.According to the psycholog ists, a person’s color preference ().

A.is formed as he grows up

B.is acquired through experience

C.is decided by his surroundings

D.is possessed from birth

3.It can be concluded from the passage that bright color lovers tend to be ().

A.quiet

B.active

C.depressive

D.pessimistic

4.The example of the bridge is used to illustrate that ().

A.people tend to kill themselves by jumping from bridges

B.color can affect people’s moods to a great degree

C.the bridge should have been repainted earlier

D.certain color can kill people sometimes

5.The notion that machines painted orange can reduce the risk of accidents ().

A.is a well-accepted fact

B.remains to be proved

C.is an illusion of workers

D.is a good wish of scientists
