Smartphone, Poor Sight

As we all know, smartphones make our lives easier, so we can find people around us always busy on them. But have you ever thought about what they mean to our eyes?

According to a survey, many people have become near-sighted（近视）because they spend too much time on the screens. When we look at something far away, our eyes blink（眨眼）about 15 times every minute. But when we look at things closer to the face, our eyes get drier because the blinkings slow down. Another bad habit is using smartphones in dark rooms before going to sleep. Bright screens can hurt our eyes and even cause more serious eye illness.

So use your smartphones wisely, and start to protect your eyes before it’s too late!

Hold the phone at least 30cm away from your eyes when using it.

Don’t forget to blink your eyes often before they get dry.

Keep the light on when you use smartphones at night.

Take a break at least every thirty minutes and look at something far away. Then try to look at the top of your nose and repeat this several times.

We often praise the world of science.

It explains the world and makes our lives easier with technology. One of the most exciting fields in science is artificial intelligence (人工智能，AI). This is an area where scientists are working on creating machines that think like humans.

However, one of the most famous scientists has a very dark warning for us about this type of technology.

“The development of full artificial intelligence could spell the end of the human race,” said Professor Stephen Hawking to the BBC.

Hawking is a well-known British physicist and author of bestselling science book A Brief History of Time. This warning came after commenting（评论）the technology he uses to speak with. As Hawking has got a serious disease called ALS, he needs an AI computer to communicate. The computer learns how Hawking thinks and suggests the words he may want to use next.

This is a basic type of AI, which is very useful, yet Hawking fears the possibility of creating technology that can match or surpass human intelligence. And it’s easy to imagine how terrible things may be. Many TV shows and films show big, killer machines that are far cleverer than us. “Humans, who are limited（限制） by slow biological evolution (进化), couldn’t compete,” said Hawking.

But not every scientist is pessimistic (悲观的) about AI technology. “I believe we will be in control of the technology for a long time,” said Rollo Carpenter, creator of Cleverbot in the UK, which is a software program that remembers past conversations. “The advantages of it to solve many of the world problems will be realized.” In what direction do you think AI is heading? Should we be hopeful or fearful?

1.Which of the following is TRUE about AI?

A. It makes our lives easier.

B. The technology is not very popular now.

C. Scientists haven’t controlled the technology.

2.The writer took Hawking as an example to ______.

A. explain how AI has helped us

B. show AI has already become part of our life

C. suggest that AI might become dangerous for humans

3.What does the underlined word “surpass” mean in the passage?

A. 象征　　　　　 B.促进　　　 C. 超越

4.We can know from the last paragraph that _________.

A. Rollo agrees with Hawking

B. Rollo is a British creator

C. Rollo invented Cleverbot in the US

5.Which of the following can be a suitable title for this article?

A. AI: a friend or an enemy

B. The future of human beings

C. The fight between humans and AI

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(近视) 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(自动眨眼) 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.
