A new chapter in space exploration has been opened up after NASA confirmed that their mission to bomb the Moon had found “significant quantities” of frozen water. Scientists said the “exciting” findings had gone “beyond expectations” as fully formed ice was found in a crater on the planet. The water was found in one mile high dust that was kicked up by the Lunar Crater Observation and Sensing Satellite(LCOSS) last month when it crashed into the Cabeus crater near the Moon's south pole.
“Indeed，yes，we found water. And we didn't find just a little bit，we found a significant amount，”said Anthony Colaprete，project scientist and principal investigator for the ￡49 million space mission.
“This is a great day for science and exploration，” said Doug Cooke，associate administrator of NASA. “The remarkable results have gone beyond our expectations. It is incredibly exciting.”
The identification of water-ice is important for purely scientific reasons，but also because a supply of water on the Moon would be a vital resource for future human exploration. The findings，which completely contradict previous beliefs that the Moon was a dry place，justify the controversial mission. Over the last decade，scientists have found some hints of underground ice on the Moon's poles，mainly in the form of compounds of hydrogen but this is the best evidence yet.
The discovery is expected to have major implications for the future of lunar exploration，and a ready supply of water could help set up lunar bases or launch missions to Mars. Mr Colaprete said that it should be possible to purify the water for drinking even though it appeared to be mixed with poisonous methanol(甲醇)．
Which of the following is TRUE of the “bombing”？

A．It damaged the Moon surface severely.

B．It would do harm to the space environment.

C．It confirmed the existence of water on the Moon.

D．It would help the research on Mars.

The underlined word “NASA” in the first paragraph maybe referred to ________.

A．a base in space

B．a new kind of bomb

C．a part of the Moon

D．a government department

Why is the finding of water on the Moon so important?

A．People on the earth use more and more water.

B．In the future lots of people will live on the Moon.

C．The water will be a supply for future human exploration in space.

D．Because the water is mixed with poisonous methanol.

How is the whole text developed?

A．Providing some facts.

B．Following the order of space.

C．Making comparisons.

D．Analyzing causes.

Which of the following is the best title of the text?

A．Water Found on the Moon after NASA “Bombing”

B．Unbelievable Space Research

C．Possible Base on the Moon

D．Mysterious Water Found on the Moon

PART THREE READING COMPREHENSION
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage.
Swaying palm trees, turquoise-blue water and sugar-white sand make beach lovers sigh with delight. But not all beaches have those ingredients. The most interesting beaches come in different shapes, sizes and colors.
Those who want beauty and something unique can go to the Seychelles’ La Digue Island. Large granite (花岗岩) rock formations overlook beautiful, white-sand beaches. The pinkish-grey rocks look like sculptures that have been forgotten on the beach. Tourists traveling to La Digue Island to see the unique rocks will also discover one of the world’s most beautiful islands.
Hawaii’s Big Island has one of the rarest beaches of all — a beach made up entirely of green sand. The sand, which is formed by dark green crystals called olivine (橄榄石), is deposited (堆积) by volcanic activity. Green Sand Beach lies on the slopes of the world’s largest active volcano, Mauna Loa.
One of the world’s most unusual beaches lies on the island of Santorini, Greece. The sand on Red Beach gets its reddish color from the red volcanic rocks that make up the cliffs (悬崖) around the beach. Tourists flock (蜂拥) to see the red sand, making Red Beach one of Santorini’s most popular beach destinations.
Black sand makes up the huge beach of Karakare. Through the years, volcanic sand mixed with iron ash to form this black beach on New Zealand’s wild, west coast. With all the beautiful beaches in the world, beach lovers have lots of choices. But for those ready for something different, a unique beach vacation might be just the ticket!

Far from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.
68. What is the text mainly about?
A. The terrible conditions in the Antarctic.
B. A special fish living in freezing waters.
C. The ice shelf around Antarctica.
D. Protection of the Antarctic cod.
69. Why can the Antarctic cod live at the freezing temperature?
A. The seawater has a temperature of -1.88℃.
B. It loves to live in the ice-salt mixture.
C. A special protein keeps it from freezing.
D. Its blood has a temperature lower than -2.05℃.
70. What does the underlined word “it” in Paragraph 5 refer to?
A. A type of ice-salt mixture.         B. A newly found protein.
C. Fish blood.                               D. Sugar molecule.
71. What does “glycol-” in the underlined word “glycoprotein” in the last paragraph mean?
A. sugar                  B. ice                    C. blood                D. molecule

It’s not easy being a teenager（13至19岁青少年）—nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you you’ll still be there for him when he needs you.
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll clam up. Instead, let him attempt to solve things by himself. At the same time, remind him that you’re always there for him if he seeks advice or help. Show respect for your teenager’s privacy（隐私）. Never read his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation（节制）. Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part–time job.
64. The main purpose of the text is to tell parents ___________.
A. how to deal with a teenager
B. how to respect a teenager
C. how to understand a teenager
D. how to help a teenager grow up
65. What does the phrase “clam up” in Paragraph 2 probably mean?
A. become excited B. show respect C. refuse to talk D. seek help
66. The last paragraph is about how to teach a teenager _________.
A. to use the phone in a sensible(明智的) way
B. to pay for his own telephone
C. to share the phone quickly
D. to answer the phone quickly
67. What should parents do in raising a teenager according to the text?
A. Not allow him to learn driving or take drugs.
B. Give him advice only when necessary.
C. Let him have his own telephone.
D. Not talk about personal things with him.
