【推荐1】Finally, you finish all your schoolwork and sit back in your chair. Suddenly you feel a headache and realize your eyes are painful. What’s going on? Doctors say that many students are spending too much time in front of screens, especially during online classes. The following might be of some help to you.
THE 20-20-20 RULE
This gives your eyes a break from long screen time: It suggests looking at something at least 20 feet away for 20 seconds after 20 minutes of work on the screen. You can then continue working.
●Studies show that people blink (眨眼睛) less often when looking at a screen. Keep your eyes wet by blinking often or using eye drops.
●Sit up straight about an arm’s length (长度) away from the screen. Make sure you’re looking down at your screen. Stand up and exercise often to avoid neck and shoulder pain.
●What about blue light blocking glasses (防蓝光眼镜)? They may look cool, but research shows that blue light isn’t the biggest cause of eye tiredness. So ask doctors about computer glasses before putting them on.

【推荐3】Your body is special—no two people in the world are alike. Although you are different from everyone else, you have exactly the same body parts as the people around you, doing different jobs that keep all of us alive.
What is inside my head?
Your head houses the most valuable part of your body-your brain. As you are reading, your eyes send pictures to your brain which makes meaning from what you see. Your brain helps you to remember and think, and makes sure your body is doing what it should.
What is my skin（皮肤）for?
Your skin covers your body. In most parts of your body, the skin is just as thick as half a centimeter（cm）. If you have your skin cut, it will have a quick cure（愈合）and stop viruses （病毒）from getting into your body. Your skin also helps you feel the heat and coldness of the environment around you. Hair grows from inside the skin. When you feel hot, extra heat comes out through your skin. As a result, your body temperature（温度）drops.
How do I move?
Muscles（肌肉）are found in most parts of your body. They work with your bones to help you move — whenever you cry or smile, eat or speak, walk or dance, etc.
Why do I breathe?
Your body needs to take in oxygen（氧气）from the air and give out the unwanted carbon dioxide（二氧化碳）in the body. When you breathe, air comes through your nose and mouth into your lungs where oxygen flows to different parts of your body.
What makes me sneeze（打喷嚏）?
When dust or a strong smell gets into your nose, you sneeze. This is the way your body cleans up the dust in your nose. Your lungs push out the air and try to clear your nose.
What does my heart do?
Your heart is a very special muscle. It is slightly bigger than your fist（拳头）and grows bigger as you do. If you place your hand on your heart, you will feel your heart beating which forces blood to move around your body.
1. Which part is the most valuable part of your body?| A．My skin. | B．My brain. | C．My mouth. | D．My nose. |
| A．Viruses can’t get into our body easily. |
| B．Our body can be guarded（保护）by our hair. |
| C．Extra heat can only stay inside our body. |
| D．We can’t feel the changes in temperature. |
| A．Sneezing is a way to clear our nose. |
| B．Our heart is the same size from birth. |
| C．We take in carbon dioxide to stay alive. |
| D．Our muscles stop working when we cry. |
| A．What Your Body Needs |

【推荐1】At the age of six weeks, Lilo seemed to be a perfect family pet. But as he grew up, he became aggressive ( 富于攻击性的). One day, as his 9-year-old owner went close, Lilo jumped at her angrily. The girl’s arm got hurt badly. It’s unusual for a family pet to hurt its loving owner. But Lilo should never have been anyone’s pet. He was actually a tiger.
There are thousands of tigers, lions and other big cats kept as pets in American homes.“People love the idea of owning something wild and special,”says Nicole Paquette of the Animal Protection Institute.“But they have no idea how hard it is to take care of them.”
Tigers like Lilo can grow to weigh 650 pounds. They are strong and powerful. Each year many people are hurt or killed by pet tigers and other big cats.
The situation can also be deadly for the big cats themselves. They often end up in small and dirty cages. Living in dirty conditions, the cats become sick and often more aggressive. Many of them die. Others are sold to roadside zoos or to hunting ranches (狩猎牧场).
Shirley Minshew works to help send some big cats to sanctuaries ( 鸟兽保护区). But as Minshew says,“Most of these sanctuaries are already full.”So are big city zoos.
The only way to solve the problem is for people to stop buying these animals.“Although they can be kept in cages, they will never be like a dog or a cat,”says Paquette.“They are wild — and they should be allowed to stay that way.”
