Every day we experiencc one of the wonders of the world around us without even realizing it It is not the amszing complexity of television. Nor the impressive tcchnology of transport The universal wonder we share and

Experience is our ability to make noises with our mouths, and so transmit ideas and thoughts to each other’s minds. This ability comes so naturally that tend to forget what a miracle（奇迹）it is.

Obviously, the ability to talk is something that marks humans off from animals. Of course, some animals have powers just as amazing. Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature’s went show, humans are a species of animal that have deve pod their own special act. If we reduce it to basie ferms, it’s a ability for communicating information to ther by varying sounds we make as we breathe out.

Not the to don’t have other powers of communication. Our facia. expressions convey our emotions, such as anger, or jout or disappointment. The way we hold our beads can indicate to others whether we are happy or sad. This is so-called “body language”. Bristling(直立的)fur is an unmistakable warning of attack among many animals. Similarly, the bowed bead or drooping tail shows a readiness to take second place in any animal gathering.

Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skill? Biologists can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history.

Passage Two

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.

People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out

of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

40. We should take good care of our eyes ______.

A. only when we cannot see perfectly

B. only when we can see well

C. even if we can see well

D. only when we realize how important our eyes are

A had been; have seen

B have been; have seen

C had been; had seen
