How to learn a foreign language? Here are some tips for you.

Listen and read every day! Listen w 4. you are on your MP3 player. Read what you are listening to. Listen to and read things that you like, things that you can m 5. understand, or even partly understand.
Take 6. (责任) for your own learning! If you do want to learn the language, take control. Choose content of interest that you want to listen and read. Pay 7. (注意) to the words and phrases that you need to understand. Do not w 8. for someone else to show you the language. Talk when you feel like it. Write when you feel like it.
Relax and enjoy 9. ! Do not worry about what you cannot remember, or cannot yet understand. It does not matter. You are learning and improving. The language will 10. (逐渐) become much clearer in your brain. So sit back and enjoy.
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 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 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 being 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.

For those who make journeys across the world, the speed of travel today has turned the countries into a series of villages. Distances between them appear no greater to a modern traveler than those which once faced men as they walked from village to village. Jet plane fly people from one end of the earth to the other, allowing them a freedom of movement undreamt of a hundred years ago.
Yet some people wonder if the revolution in travel has gone too far. A price has been paid, they say, for the conquest (征服) of time and distance. Travel is something to be enjoyed, not endured . The boat offers leisure and time enough to appreciate the ever-changing sights and sounds of a journey. A journey by train also has a special charm about it. Lakes and forests and wild, open plains sweeping past your carriage window create a grand view in which time and distance mean nothing. On board a plane, however, there is just the blank blue of the sky filling the narrow window of the airplane. The soft lighting, in-flight films and gentle music make up the only world you know, and the hours progress slowly.
Then there is the time spent being “processed” at a modern airport. People are conveyed like robots along walkways; baggage is weighed, tickets produced, examined and produced yet again before the passengers move again to another waiting area. Journeys by rail and sea take longer, yes, but the hours devoted to being “processed” at departure and arrival in airports are luckily absent. No wonder, then, that the modern high-speed trains are winning back passengers from the airlines.
Man, however, is now a world traveler and can not turn his back on the airplane. The working lives of too many people depend upon it; whole new industries have been built around its design and operation. The holiday maker, too, with limited time to spend, patiently endures the busy airports and limited space of the flight to gain those extra hours and even days, relaxing in the sun. Speed controls people’s lives; time saved, in work or play, is the important thing—or so we are told. Perhaps those first horsemen, riding free across the wild, open plains, were enjoying a better world than the one we know today. They could travel at will, and the clock was not their master.
