Ever since humans came into being on Earth, humans have always been explorers, seeking new lands and new opportunities. Now we're reaching farther than ever before. Human societies exist everywhere on Earth, even in frozen Antarctica. We have explored the deepest oceans and the highest mountains. At this moment there are half a dozen humans living aboard the International Space Station, orbiting the Earth a few hundred miles overhead. Is Mars the next human exploration destination?

　　What will we gain from going to Mars? There's no gold or silver there. No oil. No natural resources worth mentioning.

　　But it is the humans' curiosity that urges humans to explore the unknown world. New knowledge is something to treasure, for from new knowledge eventually come new abilities, and new understanding of the way the universe works.

　　Would you go to Mars, given the chance? Why not?

　　1. Which of the following is true of the plan of Mars One?

　　A. They will send two married couples to Mars.

　　B. The four people will return to Earth in 2023.

　　C. The four people will never return to the earth.

　　D. It will take 501 days for the four people to reach Mars.

　　2. What is the main idea of the third paragraph?

　　A. Surviving on Mars will be very difficult.

　　B. Mars is the most Earth­like planet.
