In the long discussion of water on the Moon, a new study contradicts(与……相矛盾)) some recent reports that say the Moon had water at the time of its formation. A group of researchers reported in the journal Science that when the Moon was created, some 4.5 billion years ago, there was not much hydrogen(氢气) on it, and therefore no water.
The researchers surveyed and evaluated this by analyzing chlorine isotopes（氯同位素） found in lunar rock samples from Apollo missions. The range of chlorine isotopes in lunar samples was 25 times that found in samples from Earth.
If the Moon had significant levels of hydrogen, as Earth did, this range would have been far less, said Zachary D Sharp, a scientist in the Department of Earth and Planetary Sciences at the University of new Mexico and the study’s lead authour.
The chlorine would have stuck together with hydrogen, forming compounds like hydrogen chloride, and escaped from the Moon’s surface, he said. The abundance of chlorine indicates a lack of hydrogen and water.
“ The amount of water on the Moon was too low for life to possibly have existed there,” he said.
Most scientists believe the Moon was formed when a large object stuck Earth, breaking off a chunk(a vast piece) that has since orbited Earth.
On Earth, goes one theory, water was released as steam form molten basalts(玄武岩) over time, eventually forming bodies of water.
“An understading of whether the Moon was dry or wet will help us understand how water appeared on Earth,” Dr Sharp said.
1. A new study indicates that _____ on the moorn.
A. there is plenty of water B. water is unlikely to exist
C. water existed in the past D. there is a little water now
2. The author would like to tell us ______ through the sixth paragraph.
A. why there is no water on the Moon B. how the Moon was formed
C. when the Earth struck the Moon D. where the Moon orbited
3. Which is NOT true according to the passage?
A. Zachary D. Sharp, a scientist of New Mexico was in charge of the new study.
B. Chlorine isotopes in lunar samples are 25 time larger than those on the Earth.
C. The more aboundant chloride, the shorter hydrogen and water.
D. The new study is benificial to understand how water appeared on Earth.
4. What can we learn from the passage?
A. There is enough water on the Earth.
B. Hydrogen chloride easily escaped from the Moon’s surface.
C. The Earth had significant levels of hydrogen.
D. Water on the Earth is directly from molten basalts.

Adults usually do not remember most of the things that are taught by their teachers at school. But this story is one such lesson that I will never forget. Every time I drift off course, I think of this story.
It was a normal Monday morning, and my teacher was teaching us on important things in life and about devoting ourselves to what is important to us. This is how the story went:
An old man lived in a certain part of London, and he would wake up every morning and go to the sub-way. He would get onto the train right to Central Lon-don, and then sit at the street corner and beg. He would do this every single day of his life. He sat at the same street corner and begged for almost 20 years.
His house was dirty, and a stench (恶臭) came out of the house and it smelled terrible. The neighbors could not stand the smell any more, so they called for the police officers to clear the place. The officers knocked down the door and cleaned the house. There were small bags of money all over the house that he had collected over the years.
The police counted the money, and they soon realized that the old man was a millionaire (百万富翁). They waited outside his house expecting to share the good news with him. When the old man arrived home that evening, one of the officers told him that there was no need for him to beg any more as he was a rich man now, a millionaire.
But the old man said nothing at all; he went into his house and locked the door. The next morning he woke up as usual, went to the subway, sat at the street corner and continued to beg.
Clearly, this old man had no great plans, dreams or anything significant (有意义的) for his life. We learn nothing from this story other than staying focused on the things we enjoy doing.
The underlined part in the first paragraph may mean ______.
A. I get tired of learning my subjects B. I fail to listen to lessons attentively
C. I go in the wrong direction of life D. I wouldn’t like to go to school
The neighbor called the police because ______.
A. the old man kept begging money from them every day
B. there was something dangerous in the old man’s house
C. the old man wouldn’t buy tickets for the train
D. they couldn’t bear the smell from the old man’s house
When the old man knew he was a millionaire, he ______.
A. remained calm B. became excited C. felt worried D. became nervous
What lesson do we learn from the story?
A. Make great plans for your life. B. Keep on doing what you like.
C. Do something that is good to society. D. Depend on yourself rather than others.

The earliest surviving Jane Austen's manuscript (手稿），a handwritten draft for a book with the name of The Watsons that was never published ，sold for 993，250 pounds in the Lon- don sale.
The sale of The Watsons draft has provided a chance to have a deep understanding of how the author wrote it and her reworkings on it, which this manuscript uniquely displays. Probably written in 1804, the novel tells the story of Emma Watson, the youngest of four sisters who is raised by a wealthy aunt but then forced to return to her family while two of her sisters search for husbands.
The novel is only a quarter complete but critic Margaret Drabble described it as “a delightful and highly complete novel, which must surely have proved the equal of her other six novels, had she finished it. ”
The Watsons contains themes found in other Austen's works and also displays her wisdom. The Watsons displays Jane Austen's unique writing style and the influence of this novel on her later works can clearly be seen. It was Austen's only literary work during the period between finishing Northanger Abbey in 1799 and starting Mansfield Park in 1811. It is not known why Austen abandoned the manuscript, though it was possibly related to her father's death in 1805.
Besides the sale of The Watsons in the London sale, the earliest rules of soccer, part of the archive (档案)of the oldest football club in the world, Sheffield FC, sold for 881,250 pounds, which attracted many people.
The Sheffield soccer sale included handwritten drafts from 1858 and the only existing copy of the printed "Rules, Regulations Laws of the Sheffield Football Club” dating from 1859, two years after the club was formed.
64. According to the text, the value of the sale of The Watsons draft lies in ____.
A. making more readers interested in the novel
B making readers know the author's writing process
C. making readers know the author's sad life better
D. making readers know the story of the novel better
65. It can be inferred from what Margaret Drabble said that ____.
A. most of the novel, The Watsons, had been finished
B. Austen wrote seven novels at the same time
C. Austen's father's death made her give up completing The Watsons
D. it is a pity that The Watsons was not finished
66. Which is TRUE about The Watsons?
A. It was Austen's first novel.
B. It was Austen's only literary work.
C. The writing style in it influenced that in Northanger Abbey.
D. It has similar themes to other Austen's works.
67. What character do the two sales share in common?
A. Both of them have handwritten drafts.
B. Both of them date back to the 18th century.
C. Both of them were widely read at the same time.
D. Both of them told us the reason for writing them.
