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. It should reduce the discomfort in your eyes.

Americans love pets. Many pet owners treat their pets as a part of the family. They treat their pets as their children—sometimes even better.

In America, there are more families with pets than those with children. 43 percent of U.S. homes have pets. Some of the pets are exotic, such as monkeys, snakes, butterflies and even wolves. Those animals come from other countries, especially China, Thailand, South Africa and so on. More common pets include fish, mice and birds. However, their favorites are cats and dogs. They sometimes have strong feelings about whether dogs or eats make better pets. “Dog people” and “cat people” often have friendly arguments about that.

People can get many benefits from pets. Pets stay with people, make people happy and help people get rid of loneliness. Therefore, most of Americans like pets. They think pets should be treated well. At least 75 animal welfare(福利) organizations have been set up in America. They provide care and good services for homeless animals. Some pets can help people live a better life. For example, researchers(研究者) have discovered that getting on with animals can help lower(降低) a person’s blood pressure. Dogs can offer protection from strange visitors. Cats can play games with the children. Some kinds of pets can provide love for their owners. In fact, to keep a pet can help a young couple have the responsibility to raise children. Pets are as basic to U.S. culture as hot dogs or apple pies. To Americans, pets are not just property(财产), but a part of the family.
