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.

Doherty and his team of scientists did an experiment to evaluate        .

A.children’s and adults’ eye-sight

B.the influence of people’s age

C.children’s and adults’ brains

D.people’s ability to see accurately

When asked to find the larger circle,         .

A.children at 6 got it wrong 79 % of the time with no gray ones around

B.only adults over 18 got it right 95% of the time with gray ones around

C.children at 4 got it right about 79 % of the time with gray ones around

D.adults got it right most of the time with gray ones around

Visual context may work when children get older than        .

A.4                           B.6                            C.10                          D.18

Why are younger children not fooled?

A.Because they are smarter than older children and adults.

B.Because their brain can hardly notice related things together.

C.Because people’s eyes become weaker as they grow older.

D.Because older people are influenced by their experience.

One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

Listen—Listen when they are talking. Don’t say anything unless they ask you a question. Sometimes it’s not necessary for you to have anything to say; they just need someone to talk to about their feelings.

Help them—If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don’t do everything they want you to do. Try to take an extra pencil or pen with you to classes in case they forget one. Have a little extra money in your pocket in case they forget something they need.

Be there for them—Be there for your friends to help make them feel better in hard times. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control, but if you can’t stay with me at my worst, you are sure not to deserve to be with me at my best.” Always remember this! If you don’t want to stay with your friends when they’re in hard times, then you don’t deserve to be with them when they’re having a good time!

_________—Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you’ll remember these things when you’re all old!

1. While your friend is talking to you about his or her feelings, you should______________.

A. give him or her some advice

    A. Life without a friend is death.

    B. A friend is easier lost than found.

    C. A friend in need is a friend indeed.

    D. A man is known by his friends.
