【题目】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.

【题目】As summer arrives, it’s important to drink more, to keep us cool. Let’s look to see what drinks are popular(受欢迎的) in the US.

Sports drinks and fruit drinks are quite popular. But there are two main(主要的) drinks that Americans enjoy most: water and soda. Around 10.9 billion gallons(加仑) of water is drunk each year, and 12.8 billion gallons of soda. Soda is the most popular drink. It’s fizzy (冒泡的) and enjoyed with friends.

That’s because it has no calories(卡路里) and keeps you fresh during sports. Besides, doctors tell us that drinking water each day is healthy.
