There are some easy things you can do to protect the environment and the earth. Choose ideas from the list or come up with a few of your own.

·Plant flowers, grass or trees.

·Whenever you visit a park or beach, take away what you bring there-keep rubbish in a bag until you can put it in a dustbin.

·Turn off the lights, TV sets when you leave the room. This saves a lot of electricity.

·Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

·Keep the doors and windows closed in winter to keep cold air in.

·Give your old books and magazines to a library instead of throwing them away.

·Give your old clothes to poor children you know instead of throwing them away.

·Use both sides of paper.

    A small plane had some trouble with its engine while it was in the high sky. The pilot knew that there was nothing he could do to keep the plane long in the air, so he rushed back to where his three passengers sat and explained the dangerous situation. At last he said, "I am a married man with three children. I am sorry to tell you that there are only three parachutes aboard. " With that he took up one and jumped out.
    One of the passengers reacted quickly. “I am a great man, I am the smartest man and the world can not do without me. "With that he too jumped out.
   The other two passengers, an old man and a young soldier, were quiet for a moment. At last the old man said, “Son, I'm old and have lived a full life. I am ready to meet my God.”
“You will have to give up that,”the young man said, smiling,“The world's smartest man just jumped out with my backpack.”

Do you know that women's brains are smaller than men's? Normally the women's brain weighs 10% less than men's. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it's what's inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount（数量）of “thinking” brain is almost the same in both men and women.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it's women who come out on top every time.
There are other important differences between two sexes（性别）. As white matter is the key to spatial（空间的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life's great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses（胎儿）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

Have you seen Avatar（《阿凡达》）? It's a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images(图像)from the movie look as if they were coming straight towards you.

More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies are more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

When we look at an object(物体), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大脑), and the brain puts them together. 3D technology uses two film projectors(投影机). One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy(头晕的) or have headaches. A famous eye doctor said if your eyes can't focus(聚焦) on the same object at once, you will have trouble watching 3D movies.

A computer can get very hot when it works on a lot of programs. It can cost a lot to cool the computer. So some scientists want to know what would happen if the heat from the computer could be used.

Large Internet companies such as Google and Microsoft have thousands of computers. As these computers deal with information， they produce lots of heat， so they need huge cooling systems. These systems send the heat into the air.

A company in Holland thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.

Boaz Leupe， head of the company， says that e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers.

Five homeowners in Holland are testing the heating system in their homes.

“We pay for the computer using， so， in that way， homeowners get heating for free.” Boaz says.

Jan Visser is one of the homeowners. “If you use the computer more， the e-Radiator producers more heat，” he says， “It cannot provide enough heat if you don't use your computer often.” But he is ready to try it. It's a great help for his family.

The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.

We know the mosquito very well. Mosquitoes fly everywhere. They can be found almost all over the world， and there are more than 2，500 kinds of them.

No one likes the mosquito. But the mosquito may decide that she loves you. She？ Yes，she. It's true that male mosquito doesn't bite（咬） and only the female mosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds， she bites. But if she doesn't like your blood，she will turn to someone else for more delicious blood. Next time a mosquito bites you，just remember you are chosen. You're different from the others！

If the mosquito likes you，she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites，you will have an itch（痒） on your body because she puts something from her mouth together with your blood. By the time the itching begins，and she has flown away.

And then what happens？ Well，after her delicious dinner，the mosquito feels tired. She just wants to find a place to have a good rest. There，on a leaf or a wall， she begins to lay eggs，hundreds of eggs.

Do you think laughter can help you deal with pain? Scientists from Britain did two experiments(实验). The first was done in a lab. People wore special wristbands(腕带). Some of them were asked to watch comedies while others watched serious programs. Then the scientists tightened(勒紧)the wristbands to see how much pain the people could feel.

The other test was done at an art festival. Some people watched a comedy show and others watched a drama(戏剧). At the same time, they had to put their backs against the wall and keep their legs bent(弯曲的)just like sitting on a chair. They did this before and after the show.

Scientists found that just 15 minutes of laughter improves people's ability to stand pain by 10%. However, the serious programs and the drama didn't make a difference to pain at all.

The study found that the magic power of laughter comes from endorphins(内啡肽). These are chemicals(化学物质). They are produced by the human body. They make you feel less pain and can make people feel happier. Exercise can produce endorphins. Your muscles(肌肉)move in and out when you are laughing. Scientists believe that this makes your muscles tiring, so we start to produce endorphins.

Scientists also found that the only real and relaxing laughter works not just polite laughter.

Next time you have a headache, get together with a group of Mends, watch a funny movie and laugh. You will soon feel a lot better because laughter is the best medicine.
