Chinese space trainer Wang Yuan has been chosen as one of the volunteers for the Mars-500 test project. He was very happy to be chosen and will accept the meaningful challenge(挑战) Another five volunteers are all space lovers., including three Russians, an Italy-Colombian and a Frenchman. They are about to feel what it’s like to travel to Mars, only without leaving the earth. They are locked up together for a year and a half under a similar condition to the red planet during the whole process. So the experiment is called Mars-500.

When reporters asked what they would miss most during the 520-day special life, French trainer Charles said:”For me, it will be mainly my family, the sun and fresh air.”

The Mars-500 test will be in a special building in Moscow, Russia. Although the people won’t leave the building, they will fell as if they are on a real trip to the Mars. The most difficult thing will be to be separated(分离) from the people that they used to live with. The trainer won’t see sunsets, sunrises, won’t feel rain for 18 months. That will be hard.

The main task is to study the “Man and environment”. It’ll care about the astronauts’ getting experience and physical effects. The 520-day-test is divided into three parts,the first 250days to Mars, the middle 30days of landing on Mars, the last 240 days to return to the earth. Everyone will stay there alone for a long time and will work lonely. They will have to make decisions themselves and only then report to the earth, and the earth will tell them whether they do the right thing or not.

Each astronaut is preparing for the great challenge. It is learned that they will be launched（发射）early in June. And the experiment will end in November 2011.

Always forgetting your long passwords(密码)? Worried about being hacked(被攻击)?All these worries will soon become history. Scientists have found that upper-casing(大写)your password can help you reduce the chance being hacked.

Usually passwords are six letters or more.However,50 percent of people choose a common word or simple key combination for their password. The most used passwords are 123456, abcdef and abc123. In fact, if your passwords are in lower-case(小写),it will be easily hacked by a hacker. According to a study, it only takes a hacker ten minutes to hack a six-letter password which is in lower-case, but if you make the letter in upper-case, it can take up to ten hours. So if you want to make your account much safer, you should make your password upper-case. Of course, you can also add numbers or symbols to your password. Most of the time a hacker’s computer has to work for 18 days to break a password, but if you choose a nine-letter password that includes numbers and symbols, it can take a hacher’s  computer 44,530 years to break it.

Friends play an important part in our lives, and although we can’t be more familiar with the fact of friendship, we often don’t clearly understand how we make friends, especially with Americans. Here are some pieces of advice on making friends with Americans:

* Visiting places Americans enjoy: parties, churches, restaurants, parks and sports clubs.

* Be willing to take the first step. Don’t wait for them to get close to you. Americans in China may not know you speak English. They may be uncomfortable if they can’t speak your language.

* Use small talks to open the conversation. Ask them where they’re from, why they come to China, etc. Remember: Be careful not to ask personal questions about age, salary and so on.

* Show an interest in their culture, their country or their job. Americans like to talk about themselves.

* Invite them to join you for dinner or just for coffee or tea. Try to set a specific （明确的）time. Americans sometimes make general invitations like “Let’s go out for a dinner sometime.” Often this is just a way to be friendly. It’s not always a real invitation.
