          閱讀理解,閱讀下列短文,從每小題所給的A、B、C、D四個選項中選出最佳選項。

             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 (視力綜合癥).

          Nathan Warford is an optometrist (配鏡師) 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.           D. Having tired 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 don’t want their parents to worry

            D. 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           D. one fourth 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

            D. an optometrist can’t help children with their eye problems at all

          5. What is the passage mainly about?

            A. People who often get headaches.

            B. Some information about the latest digital products.

            C. Dr. Warford’s experience of working out eye problems.

            D. Eye problems in children caused by using digital products.
