Smartphones, poor sight

Look around and you’ll see people busy on their smartphones. Smartphones do make our lives easier . But have you ever thought about what they mean to your eyes?

According to a study, half of British people own smartphones and they spend an average (平均) of two hours a day using them. There has been a 35% increase in the number of people in the UK who suffer from shortsightedness（近視）since smartphones were introduced there in 1997.

Staring（盯）at smartphones for long time gives you dry eyes. When looking at something in the distance, your eyes automatically blink（自動眨眼）a certain number of times. However, when you look at things closer to your face, the blinking slows down. This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using smartphones in dark rooms before going to sleep. If you look at a bright screen while your pupils（瞳孔）become larger, too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma（青光眼）.

While you’re probably not going to stop using to your smartphone, there are a few things you can do to protect your eyes. Hold your phone at least 30 centimetres away from your eyes when using it. Take a break every hour and try the following: look at something at least five meters from you and then focus on the tip of your nose. Repeat this several times. It should reduce the discomfort in your eyes.

A. most of the British people began to use smartphones 19 years ago

We are all busy talking about and using the Internet, but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.

At first the Internet was only used by the government (政府), but in the early 1970s, universities , hospitals and banks were allowed (允許) to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software (軟件) that made "surfing" (瀏覽) the Internet more convenient (方便).

Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.The Internet has now become one of the most important parts of people's life.
