Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.
Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.
Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.
Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in the space industry!
While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

When someone has deeply hurt you, it can be extremely difficult to let go of your anger. But forgiveness is possible and it can be surprisingly 36 to your physical and 37 health.
"People who forgive 38 less depression, anger and stress and more hopefulness," says Frederic Luskin, Ph.D., 39 of Forgive for Good. "So it can help 40 on the .wear and tear on our organs, reduce the wearing out of the immune system and 41 people to feel more vital."
So how do you start the forgiveness? Try 42 these steps:
Calm yourself. To defuse (缓解) your 43 and try a simple stress-management technique.
"Take a couple of breaths and think of 44 that gives you pleasure: a 45 scene in nature, someone you love," Luskin says.
Don’t 46 an apology. "Many times the person who hurt you has no 47 of apologizing," Luskin says. "They may have wanted to hurt you or they just don’t see things the same 48 . So if you wait for people to apologize ,you could be waiting a(n) 49 long time. "Keep in mind that forgiveness does not necessarily mean 50 to the person who upsets you.
Take the control away from your offender. Mentally replaying your 51 gives power to the person who caused you pain. " 52 of focusing on your hurt feelings, learn to look for the love, beauty and kindness 53 you," Luskin says.
Try to see things from the other person’s perspective (立场；视角). If you empathize (有同感) with that person, you may 54 that he or she was acting out of ignorance, fear even love.
Recognize the benefits of forgiveness. Research has shown that people who forgive report more energy, better 55 and better sleep patterns. Don’t forget to forgive yourself. "For some people, forgiving themselves is the biggest challenge," Luskin says.
"But it can rob you of your self-confidence if you don’t do it. "

If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven"t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater, the younger people learn a second language.
A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
"Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),"he said. "You are actually going beyond language and have a better understanding of different ideas."
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.

When Xia Min started drinking alcohol with her classmates at a friend’s birthday, she didn’t realize what would happen to her. She drank a lot and fell into a coma (昏迷). The 15year-old girl from Chongqing never recovered.
Xia’s death is warning to other students. A new rule went into effect on January 1, 2006. Teens are not allowed to buy or drink alcohol. Shops are not allowed to sell it to them.
A 1999 Chinese law forbade (禁止) shops to sell alcohol to youths under 18. But it is not taken seriously by shopkeepers because it doesn’t have specific rules. People hope the new rule will work.
“I tasted alcohol when having the dinner of the last New Year’s Eve,” said Lian Yuqi, a 16-year-old girl in Xiamen. She believes that the new rule will stop teens from drinking and help them grow in a healthy way.
“Although it may be a little disappointing not to have beer at parties, I think we can have soft drinks instead,” she said.

Imagine a boy from a small village in East Africa, He from a very early age has been looking after cattle. At twelve years old he knows more about cattle than most of you. However, he has never been to school. Has this boy ever had any education?
Education is discovering about ourselves and about the people and things around us. All the people who care about us — our parents, brothers, sisters, friends — are our teachers. In fact, we learn something from everyone we meet. We start learning on the day we are born, not on the first day" we go to school. Every day we have new experiences, like finding a bird"s nest, discovering a new street in our neighborhood, making friends with someone we didn"t like before. New experiences are even more fun when we share them with other people.
Encouragement from the people around us enables us to explore things as much as possible. As we grow up, we begin to find out what we are capable of doing. You may be good at cooking, or singing or playing football. You find this out by doing these things. Just thinking about cooking doesn"t tell you if you are good at it.
We learn so much just living from day to day. So why is school important? Of course you can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who can" t do everything for themselves. At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.
