When you are feeling unhappy or forget how great you are, these are six ways to make you feel good about yourself.
1) Look in the mirror and say to yourself, “I am a special person and there's no one in the world like me. I can do anything!” It may not sound so good, but it really works!
2) Do something nice for someone. Helping others always makes you feel good.
3) Smile! Be friendly to people you meet. Look for the good things in your friends and family.
4) Learn something new! Have you always wanted to decorate your own room or learn how to swim? New challenges are fun and give you a sense of accomplishment when you have finished.
5) Read and start a diary. Turn off the TV and let your imagination fly! Write down your thoughts, dreams or anything you want! Writing always helps to express your feelings.
6) Stay with your family. We all need our family time. Talk with your Mum or Dad or maybe even your cousin.

When an animal helps another animal，it usually gets something valuable in return. For a long time，many scientists thought that only people could act generously just because it feels good.
However，a new study in Germany suggests that chimpanzees (an animal like a large monkey without a tail ) also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor about 6million years ago.
People and chimpanzees appear to develop such features without any other training，says Warneken，a scientist in Germany.
Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment，a person tried to reach his arm into a cage to get a stick，but he couldn't reach it. A chimpanzee was in the cage，and it could reach the stick if it wanted to.
Thirty-six chimpanzees took part in this experiment one by one，and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn't met the person before，they usually took the stick and gave it to the person. What's more，they did this whether or not the person offered them bananas as a reward.
In a similar experiment，36 children acted in a similar way. They helped the person reach the stick，whether or not they were offered toys for their help.
Researchers did other experiments on chimpanzees and babies. No rewards were offered in either experiment. And still，both the chimpanzees and children went out of their way to help. Still，the new study is different from earlier findings. Researchers have found that chimpanzees don't give rewards of food to other chimpanzees，even if it costs them nothing to be generous.

Whether yellow, red or white, the onion is a vegetable that you may not know well. The list of its uses in cooking is endless. People have used onions to add flavor(味道) to their foods for thousands of years. Besides onions' great taste, they are very good for you. They have special chemicals(化学物质) that improve your ability to fight off sickness and you have fewer chances of getting a disease.

No matter how good onions are for you, it is difficult to cut an onion without your eyes filling with tears! When you cut into an onion, irritating(刺激性的) chemicals inside the onion will get into the air. They touch your whole eyes and cause pain. Your eyes make tears to wash away the chemicals and protect your eyes.

Luckily, cooks and scientists have discovered some ways to keep you from crying when you cut up onions：

Cut the onion under running water. The water will wash away the chemicals before they can reach your eyes.

Use a fan to blow air over the onion as you cut it. The air will blow the chemicals away from your eyes.

Put the onion in a fridge for an hour before cutting. This helps make the chemicals in the onion move slowly, so they may not ever reach your eyes.

If you try out these good ideas and still cry while cutting onions, don't worry. Scientists think if you cut more onions, your body will become more resilient to the onion's chemicals. So the tears will not last long. If you think about how healthy onions are, you might even call those tears "happy tears"．
