Nowadays, many children spend hours a day looking at computer screens or other digital products. Some eye doctors say all the screen time has caused more children to have what they call computer vision syndrome(视力综合症).
Nathan Warford is an optometrist (配镜师) in the US. He says he has seen more children having eye problems.
“More children come into my office because their parents have noticed that they have headaches or red eyes, or because their degree of short-sightedness appears to be increasing very fast and they’re worried,” he said.
Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don’t tell their parents, because they don’t want their games or the computer to be taken away.
Another part of the problem is that people blink(眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about one third as much as we normally do in everyday life. If eyes can’t stay wet or are too tired, they will not be protected like normal.
1.Which of the following isn’t caused by too much screen time?
A. Having headaches. B. Having wet eyes. C. Having red eyes.
2.Some children don’t tell their parents when their eyes start to feel uncomfortable because .
A. they think it is not serious
B. they want to go to hospital themselves
C. they want to continue playing computer games
3.People blink as they normally do when they use computers.
A. one third as much B. two thirds as much
C. half as much
4.From the passage, we can learn that .
A. tears can’t protect eyes
B. less screen time is good for eyes
C. children should blink as much as possible
5.What is the passage mainly about?
A. People who often get headaches.
B. Some information about the latest digital products.
C. Eye problems in children caused by using digital products.

Seeing is believing(相信),but if our eyes don’t work, how can we see to believe?
Today more and more kids wear glasses before going to middle school. Because they spend too much time watching TV or playing computer games without a rest. But we must do something to protect(保护)our eyes because they are important for us to see the world.
Love your eyes. Every day , when we open our eyes, we can see the lovely friends and parents, beautiful flowers and green trees. Without them, there is only darkness. It is like a house without any light. How important our eyes are!
Remember to rest your eyes. When you use the computer for an hour or two, it is time to stop to have a 30-minute rest. At school, you need to do eye exercises. Closing your eyes for resting is helpful, as well as looking at green trees or grass. In these ways, your eyes will feel relaxed.
Have good habits. When writing homework and reading, it is important to keep a distance of 30 cm between your eyes and books. We should never rub(摩擦)our eyes with dirty fingers. Before and after swimming, use eye drops. Eat something healthy for eyes, such as carrots, fish and eggs.
1.We must protect our eyes because .
A. seeing is believing B. We have to wear glasses
C. eyes are important for us D. we use them to watch TV

A. two B. three C. four D. five
3.We can learn from the passage that .
A. the world is dark if we don’t have eyes B. many kids wear glasses before going to school
