    Almost every day, we discuss the topic of health, especially for kids. But what is health? "Health" means
eating well, getting enough exercise, and having a healthy weight. Let's read the following rules. They can
help you stay healthy.
   1. Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can
help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the
nutrition (营养) we need by eating different kinds of food, especially fruit and vegetables. 
   2. Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty
of calcium (钙) to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups
of milk(1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less
sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important
nutrition.
   3. Listen to your body. When you are eating, notice how your body feels. When your stomach feels
comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can
make you unhealthy and fat.
   4. Limit (限制) screen time. What's screen time? It's the amount of time you spend watching TV, movies,
and playing computer games. The more time you spend on these sitting-down activities, the less time you
spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend
no more than 2 hours a day on screen time.

     Food is life; it gives us the nourishment (营养) we need to stay alive and be healthy. Usually, we eat
because we are hungry or need energy. Brian Wansink, a professor (教授) at the University of Illinois, says
we also eat certain (某种) foods because they make us feel good, and remind us of happy memories. Wansink
calls this kind of food comfort food. For some people, ice cream is a comfort food. For others, a bowl of
noodles makes them feel good.
     How does a food became comfort food? Professor Wansink believes that we connect food with important
times, feelings, and people in our lives, 'When I was a child, my mother made a delicious soup; I loved it.
Now, I often eat this soup when I am tired or worried, and it helps me feel better,' says one of Wansink's
friends.
     Do men and women choose different comfort foods? Wansink's research (研究) at the University of
Illinois says 'yes'. In his study, the favorite comfort for both men and women was ice cream. After this,
men usually preferred hot, delicious foods like soup or noodles. Women liked sweet things such as chocolate
and candies. Men and women like to eat comfort foods when they are happy, but women eat these foods
more when they are sad or worried.
1. According to the passage, a kind of food that makes us feel good is called ________.
A. fast food
B. healthy food
C. Chinese food
D. comfort food
2. In Wansink's study, both men and women like to eat ________.
A. soup
B. ice cream
C. noodles
D. chocolates
3. The passage implies (暗示) that ________.
A. men probably eat more comfort foods than women
B. women usually eat comfort foods only when they are happy
C. men usually eat comfort foods when they are sad

     Computers can injure (伤害) you. Most other injuries happen suddenly. For example, if you fall off a bike
and break your arms, it happens very quickly. But computer injuries happen slowly.
     You probably know how to ride a bike safely. Now learn to use a computer safely.
     Your eyes
     Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at
least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes
a rest.
     When you use a computer, the window should be on your left or your right. If it is behind you, the light
will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into
your eyes.
     Your hands and wrists
     Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundr-eds of
times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on some-thing. 2)
Keep your elbows (肘) at the same height as the keyboard. 3) Stop sometimes and exercise your hands, wrists
and fingers in a different way.
     Your back
     Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your
back or your neck. So you should sit with your back straight. The top part of the screen should be in front of
your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel (平行) to the floor.
If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.
