Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expection of fame and glory┅ For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.

There are alreafy too many people on the Earth. I think that something before the end od the century, there will be a human colony on Mars. It will happen when people finally realize that two-way trips to the red planet Mars are unnecessary. Most of the danger of space flight is in the launches and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead, and every two years moresupplies and more people will be sent to the new colony. Mars has all the materials for a colony to produce or make everything it needs, and Mars is far more pleasant than the other plants in the outer space.

Being able to multitask---doing several things at the same time---is considered a welcome skill by most people. But if we consider the situation of the young people aged from eight to eighteen, we should think again.
What we often see nowdays is that young people juggle an ever larger number of electronic devices(电子产品)as they study. While working, they also surf on thr Internet, send out emails, answer the telephone and listen to music on their ipods. In a sense, they spending a significant amount of time in fruitless efforts as they multitask.
Multitasking is even changing the relationship between family members. As young people give so much attention to their own worlds, they seem to have no time to spend with the other people around them. They can no longer greet family members when they enter the house, nor can
