【推荐1】Do you like watching TV or playing games? How many hours do you use your phone a day? We call the time we spend on TV, computers and phones “screen (屏幕) time”.

In a study (研究), scientists (科学家) ask 577, 000 children how much time they spend on screens, schoolwork and sports every day. They find about 68% of them spend more than 2 hours on screens.

Two hours of screen time a day is bad for children’s health. The study shows harm (伤害) starts after 75 minutes of screen time for girls and 105 minutes for boys. Why is that? “Just because ▲ . In our study, 24% of boys spend an hour a day doing sports, but only 14% of girls do that,” Dr. Khan says.

So it is important for students to do sports and balance (平衡) their screen time. Tom has a “three-time system(系统) for his son Patrick—a “go time” for schoolwork, a “slow time” to play games or talk with friends on the Internet and a “green time” for sports. “We need to get children out and move. They can walk, ride a bike and play football,” he says.

【推荐2】You may know that exercise can help you lose weight (减肥). However, it has a lot of other good effects (影响), too. Even if you are healthy or fit, there are several reasons that you should exercise.

First, exercise can give you energy (精力). When you are tired during the day, take a walk or go for run. Scientists looked at 70 different studies about exercise and tiredness. Over 90 percent of the studies showed the same results: exercise increased (增加) energy and reduced tiredness.

Second, exercise can help you sleep better. Not having enough sleep is one of the main causes of stress (精神压力). Exercising raises your body temperature. Then it goes back to normal about five to six hours later. You become sleepy at this point because the drop in temperature tells your body that it’s time to sleep.

Also, exercise can reduce stress and worry. Do you ever feel nervous or stressed? Doing sports for 20 minutes can make you feel relaxed. How? When you exercise, you have to focus on (专注于) your body, so you can’t think about your stressful thoughts.

【推荐2】How quickly can you count from one to ten? Do you use ten different words to do it? Can you do it in English, or do you have to use your first languages? Do you count on your fingers? Many people think that numbers and math are the same all over the world. But scientists have discovered that it is not true.

People in different parts of the world use different ways to count on their fingers. In the United States, people think begin counting with their first fingers, which they extend or stick out. They then extend the rest of their fingers and finally the thumb(拇指) to count to five. Then they repeat this with the other hand to get to ten. In China, people count by using different finger positions. In this way, a Chinese person can easily count to ten on only one hand.

Besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. Some languages have only a few words for numbers, and others have no words for numbers. A group of scientists studied aboriginal(土著的) people in Australia. These people don’t have hand movements to stand for numbers. They don’t even have word for numbers. However, they are still able to understand different ideas about numbers.

In a similar study, researchers from the Massachusetts Institute of Technology discovered that people of the Piraha tribe (部落) in northwestern Brazil don’t have words for numbers such as “one” or “three”. They are not able to say “five trees” or “ten trees” but can say “some trees”, “more trees” or “many trees”. Professor Edward Gibson said that most people believe that everyone knows how to count, “but here is a group that does not count. They could learn, but isn’t not useful in their culture, so they’ve never picked it up.”

Although all humans are able to understand quantities(数量), not all languages have numbers and not all people use counting. Number words in a certain language are a result of people needing numbers in their daily lives. Now we know that people have different ideas about numbers and math, too.

【推荐3】It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold! Wait a moment. Could it just be a common cold or the flu that’s been going around?

A cold gives you a runny nose and a cough. But it’s usually easy to deal with. Some people take medicine while others have herbal tea or chicken soup. Usually you feel better after a week.

On the other hand, the flu can be much more dangerous. It usually gives you a fever. Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.

Don’t worry. If you get a flu vaccine(疫苗), it can protect you from getting the virus(病毒). Flu vaccines work by giving the body a small number of flu viruses. This causes your body to develop antibodies(抗体). So next time you get the flu, the antibodies will help you.

The flu virus changes every few years. Therefore, there are so many types of flu, such as H1N1 and H5N1. The antibodies for one type of flu can’t help us against all types of flu. That’s why we need to get the vaccine every year.

However, healthy habits may also help stop you from developing a cold or the flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen your immune system(免疫系统).
