TaIL Spin

Two dolphins race around in a big pool in the Ocean Park. The smaller dolphin Grace, shown off a few of her tricks, turning around and waving hello to the crowd. The most amazing thing about her, however, is that she’s even swimming at all. She doesn’t have a tail.

Grace lost her tail as a baby when she got caught up in a fish trap. When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life. “Is she going to make it?” Her trainer, Abbey Stone, feared the worst. Grace did make it --- but her tail didn’t. She ended up losing her flukes and the lower part of her peduncle.

Over the past six years, she has learned to swim without her tail. Dolphins swim by moving their flukes and peduncle up and down. Grace taught herself to move another way---like a fish! She pushed herself forward through the water by moving her peduncles from side to side.

The movement put harmful pressure on Grace’s backbone. So a company offered to create a man-made tail for her. The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn’t hurt her.

The first time Grace wore the artificial tail. She soon shook it off and let it sink in the bottom of the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time, others not at all. “The tail isn’t

necessary for her to feel comfortable,” says Stone, “but it helps to keep that range of motion(动作) and build muscles(肌肉).”

Now, the dolphin is about to get an even happier ending. This month, Grace will star in Dolphin Tale, a film that focus on her rescue and recovery. Her progress has inspired more than just a new movie. Many people travel from near and far to meet her. Seeing Grace swim with her man-made tail gives people so much courage.

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.

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

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

  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.

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.

The garden city was largely the invention of Ebenezer Howard (1850-1928). After immigrating from England to the USA, and an unsuccessful attempt to make a living as a farmer, he moved to Chicago, where he saw the reconstruction of the city after the disastrous fire of 1871. In those days, it was nicknamed “the Garden City”, almost certainly the source of Howard’s name for his later building plan of towns. Returning to London, Howard developed his design in the 1880s and 1890s, drawing on ideas that were popular at the time, but creating a unique combination of designs.

The nineteenth-century poor city was in many ways a terrible place, dirty and crowded; but it offered economic and social opportunities. At the same time, the British countryside was in fact equally unattractive: though it promised fresh air and nature, it suffered from agricultural depression (萧条) and it offered neither enough work and wages, nor much social life. Howard’s idea was to combine the best of town and country in a new kind of settlement, the garden city. Howard’s idea was that a group of people should set up a company, borrowing money to establish a garden city in the depressed countryside, far enough from existing cities to make sure that the land was bought at the bottom price.

Garden cities would provide a central public open space, radial avenues and connecting industries. They would be surrounded by a much larger area of green belt, also owned by the company, containing not merely farms but also some industrial institutions. As more and more people moved in, the garden city would reach its planned limit--- Howard suggested 32,000 people; then, another would be started a short distance away. Thus, over time, there would develop a vast planned house collection, extending almost without limit; within it, each garden city would offer a wide range of jobs and services, but each would also be connected to the others by a rapid transportation system, thus giving all the economic and social opportunities of a big city.

1.How did Howard get the name for his building plan of garden cities?

A. Through his observation of the country life.

B. Through the combination of different ideas.

C. By taking other people’s advice.

D. By using the nickname of the reconstructed Chicago.

2.According to Howard, garden cities should be built _____.

A. as far as possible from existing cities.

B. in the countryside where the land was cheap.

C. in the countryside where agriculture was developed.

D. near cities where employment opportunities already existed.

3.What can we learn about garden cities from the last paragraph?

A. Their number would continue to rise.

B. Each one would continue to become larger

C. People would live and work in the same place.

D. Each one would contain a certain type of business.

4.What could be the best title for the passage?

A. City and Countryside

B. The Invention of the Garden City

C. A New City in Chicago

D. A Famous Garden City in England

 

A boy was walking home from school when he saw a large, tempting(诱人的) apple on one of the branches of an apple tree hanging out over a tall fence.

The more he looked at it, the    28   he felt and the more he wanted that apple.

He stood on tiptoe(脚尖), ___29  as high as he could , but even at his tallest  30___ he was unable to touch it. He began to  31  up and down, as high as he could, at the  32 of each jump stretching his arms to get the apple. Still it remained out of  33 .

Not giving up, he thought, if only he had something to  34 on. His school bag wouldn’t give enough height and he didn’t want to  35  the things inside, like his lunch box, pencil case, and Gameboy.

He had tried everything he could think to do.   38  seeing any other choices, he gave up and started to walk   39 .

I don’t have the apple and I’m feeling miserable as well. There’s  44  more I can do to get the apple—that is unchangeable—but we are supposed to be able to  45 our feelings. If that’s the case, what can I do to feel better?
