er and harder to predict. Change is coming so fast that some of the most important technologies of the 21st century may now be just a sketch on the drawing board or glimmer in the mind of genius. Then again, the transcendent technologies may be right under our noses on the verge of having as great an impact as the car or telephone.

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.

31.Seeing and perceiving are().

A.the same action

B.two separate actions

C.two actions carried on entirely by the eyes

D.several actions that take place at different time

32.Perceiving is an action that takes place().

A.in our eycs

B.only when we think very hard about something

C.only under the direction of a psychologist

D.in every person's mind

33.People perceive different things about the same scene because().

A.they come from different countries

B.they can't agree about things

C.some have better eyesight

D.not clearly mentioned in the passage

34.Psychologists study perception by().

A.setting up many experiments

B.asking each other what they see

C.looking out of the window themselves

D.studying the differences in people's eyes

35.The best title for this passage is().

A.How We See

B.Learning About Our Minds Through Science

C.What Psychologists Perceive

D.How to Become an Experimental Psychologist

ver？ If you have, don’t feel alone! It’s a very common, natural wish that has a long history.Spanish explorers of the sixteenth century even tried to find a fountain of youth in what is now the state of Florida.The water the this legendary fountain, which no one has yet found, was believed to restore youth and good health to those who drank it.

Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.

Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.

Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.

One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.
