Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled—they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.

Can you imagine traveling to work in a one – man submarine? Some scientists believe that some day one – man submarines will be as many as automobiles are today．A famous French driver says, “One day soon, men will walk on the ocean floor as they do on the street!” Perhaps during your lifetime people will travel, and live in the sea．
If human beings want to live in the ocean, many human problems will need to be studied first.
Some of these problems, similar to those of living in outer space, are pressure, lack of oxygen and weightlessness. Many questions are still unanswered．For example, can our blood make itself fit for underwater surroundings? What will happen to our muscle if we live in the water very long? Scientists are looking for answers．
Perhaps in the future man will live in the sea, away from the crowded and noisy cities on land．Then sea has plenty of space, not only for floating living buildings and parks, but also for storing supplies and for underwater travel．
Some scientists believe that ocean living will benefit man in more than physical ways. In the freedom and beauty of the deep sea, man may find new sources of joy．

2.Why do some people hope to leave cities to live in the sea? Because_____． ( )
A．people think they can live crowdedly in the sea
B．people wish to go the quiet seafloor to travel for several days
C．people want to break away from the crowded and noisy cities where they live now
D．only in this way can people get rid of noise pollution
3.In what ways could ocean living be helpful for man? ( )
A．People can swim freely as much as possible．
B．People can be interested in the new pleasure there isn’t anywhere else．
C．The sea can supply people with enough foods and other things, so people needn’t work．
D．People can go boating and go to the park as often as possible．
4.Which of the following is the similar problem as that of living in outer space? ( )

D．We can finds new joys．
5.Which of the following statements is true according to the passage? ( )
A．The scientists have not solved the problem of weightlessness underwater．
B．The scientists have solved the problem of weightlessness when man live in space．
C．Some scientists believe that ocean living will benefit man in no more than physical ways．
D．Sea has plenty of space only for floating living buildings and parks．
After 21 years of marriage, my wife wanted me to take another woman out to dinner. 36 woman was my mother, who has been a widow for 19 years, but my work had made 37 impossible to visit her very often. That night I called to 38 her to go out for dinner.“What’s wrong? Are you 39 ?”she asked. “I thought that it would be 40 to spend some time with you. Just the two of us,”I answered.

At that moment, I understood the importance of saying in time“I LOVE YOU”. Nothing in life is more important than your 54 . Give them the time they deserve, because these things cannot be 55 till“some other time”.
