A
September 21,—At a press conference today it was announced that the first tourist heading for Mars will be the 38-year-old US businessman Patrick Clifford.He will leave the earth in the launching window of June and set his foot on the surface of Mars in November,together with the other 6 astronauts assigned for the mission to further explore the planet.
Patrick has now two years of training ahead of him to get ready for the trip.Not only will he spend five months in getting to Mars,but another 600 days there before he can go back home.Patrick was of course very ey dream since I was four,and seeing the first man on Mars 20 years ago made me realise that it was possible.”
To be able to pay the $1.3 billion for his ticket for the trip Patrick sold his majority stake(股份) in the company his father had built.“I know that my fathe r would have been proud of me if he had still been alive today,and he knew what this means to me,”says Patrick.There is no risk though that you will find Patrick begging in your street corner when he comes back,but it is said that he was paid twice as much for his part of the company.
So,how is he going to spend his 600 days on the red planet?“Well,since I don’t have a job when I get back after selling the company,I have plenty of time to come up with a new business idea,”he says and laughs.If he brings a shovel(铁锹) he can start building the first hotel there,but maybe he shouldn’t eany guests until someone can offer a cheaper ticket.
1.How long will Patrick Clifford be away before he comes back?
A.About five months.
B.About two years.
C.About 600 days.
D.About 750 days.

B
Astronomers have found patches(斑块) of frost scattered around the moon’s north and south poles which could one day provide a source of water for human visitors.The scientists spotted the signature of frozen water in infrared(红外线的) measurements taken by Nasa’s moon mineralogy mapper,an instrument that flew on India’s Chandrayaan-1 mission to the moon a decade ago.The freshly-analysed data show that water ice lies low on the ground near the moon’s polar regions that are permanently in shade and so sheltered from the heat of the sun’s rays.
Most of the ice was found near the moon’s south pole around a bunch of craters.In the north,the patches of ice appeared to be more separated,according to Shuai Li at the Hawaii Institute of Geophysics and Planetology in Honolulu.Follow-up measurements of the ice patches found that they tended to form where the surface temperature never rose above -163℃,but temperature alone was not
enough to guarantee frozen water:only 3.5% of the shadowy areas the scientists checked for water revealed notable signs of ice.
The images are the first “direct and definitive evidence” of water ice that is eoon,according to a report in the ProceedingsoftheNationalAcademyofSciences.“These ice deposits might be put to use as a local resource in future eoon,” the authors write.
The Indian Space Agency launched its Chandrayaan-1 mission to the moon in and was swiftly rewarded with evidence of frozen water on the lunar surface a year later.Rather than sheets of ice on the surface,the water is thought to eolecules(分子) bound to grains of moon dust.
Soon after the Indian feat,Nasa crashed a spacecraft into the 100km-wide Cabeus crater which is in permanent shade on the moon’s south pole.The intentional act of lunar violence threw up some pieces of soil from which scientists were able to confirm the presence of water on the moon.
4.What can we infer from Paragraphs 1 and 2?
A.Chandrayaan-1 was rewarded with glory.
B.Frozen water is believed to have been found.
C.Astronauts spotted the signature of frozen water.
D.Humans enjoyed a leap in moon exploration.
答案:D
解析:推理判断题。

由第一段
“...whichcouldonedayprovideasourceofwaterforhumanvisitors.”可推断出,作者认为新发现的水资源使得未来人们的登月旅行成为可能,可以说这是人类在月球探索上有了飞跃。

故选D项。

5.Which of the following best explains “deposits” underlined in Paragraph 3?
A.Fund.
B.Part of the cost.
C.A natural accumulation.
D.Money in a bank account.
