At first sight the planet Mars(火星)does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles(161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes(火山); the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists.

Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide, simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between

100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.

Imagine someone who has spent the majority of their life sitting with a sign on the side of the road and that very person giving someone their last 20 dollars. That’s exactly what Marine Corps veteran (退伍军人) Johnny Bobbitt, 34, did in October in Philadelphia.

Bobbitt served in the U.S. Marine Corps and worked as a paramedic (医务辅助人员) in Vance County, N. C. before he became homeless. Nobody knew how he got to where he was because he was discreet about that.

One night in October, Bobbitt was sitting roadside with a sign in Philadelphia as usual, when Kate McClure of Florence Township, N. J. was driving home down Interstate 95 and ran out of gas. Scared and nervous, she got out of the car to head to the nearest gas station. As McClure was heading to the nearest gas station, she ran into　 Bobbitt and he told her to get back in the vehicle and lock the door. Minutes later, he appeared with a red gas can. He’d used his last $20 to buy her gas.

After that unexpected meeting, McClure and her boyfriend, Mark D’Amico, who both live in New Jersey, visited Bobbitt several times to deliver gift cards, cash, snacks and toiletries. They then decided to create a fund raising page so he wouldn’t have to spend the holidays sleeping on the street.

McClure started the GoFundMe page on November 10. With the page, the couple hoped to raise $10,000, enough money for his rent, a reliable vehicle and up to six months’ expenses. Bobbitt’s story ran in a local paper. By November 15，more than 10,000 local people had made donations through the GoFundMe page and more than $300,000 had been raised.

On Thanksgiving, Bobbitt was resting in a hotel, his feet up on the bed, drawing up a grand plan for his new life, thanks to several thousand dollars raised to repay him for a good deed.

1.What does the underlined word “discreet” in paragraph 2 most probably mean?

A.Doubtful. B.Cautious.

C.Guilty. D.Optimistic.

2.McClure met Bobbitt when she　　　　 .

A.couldn’t find a gas station B.got to the way home

3.It can be known from the text that　　 .

A.Bobbitt’s story obtained wide attention

B.Bobbitt became world-famous overnight

C.the GoFundMe page collected over $400,000 for Bobbitt

D.the GoFundMe page was started to help people like Bobbitt
