Joker found one of the biggest diamonds in the world in his own backyard. He sold the stone to a diamond dealer for over three hundred thousand dollars. In New York, the diamond was resold，this time for almost eight hundred thousand dollars. The true value of a diamond is never known until it has been cut. Once cut successfully, its value can increase a thousand times. It’s easy to understand why the owner of the Joker diamond went to the best diamond cutter he knew, Kaplan. The cutter studied the diamond for twelve whole months.
When he felt he was ready to start work, he discovered a flaw （瑕疵）. He had to begin with his calculations all over again, or he might have made the stone useless. Six more months passed, and Kaplan finally said to the owner, “I am ready to start my work. There will be one excellent diamond that will be comparable to any in the world, plus eleven small diamonds of first-class quality. ” Kaplan waited a few more days until he felt he was in the best physical and mental （精神的） condition possible. He picked up his tools and held his breath as he made the first blow. The diamond split （切开） exactly as he promised.A diamond dealer is a person ______,

Before the early 1960’s people interested in the differing roles of the left and right hemispheres(半球) of the brain depended almost entirely on facts drawn from animal research, form studies of patients with one-sided brain damage. But it was possible to find out which brain hemisphere was most involved in speech and other functions in normal people by having them listen to two different words coming to the two ears at the same time. This became known as the “dichotic listening” procedure. When several word pairs are given in a row, people are unable to report them all, and most right-handers prefer to report, and report more correctly, words given to their right ears. This seems to be related to the fact that signals from the right ear, although sent to both hemispheres, are better sent to the left hemisphere which controls speech. People who have speech represented(回忆) in the right hemisphere, a very unusual occurrence even in left-handed people, more correctly report what their left ears hear.
In contrast to the right-ear advantage for speech, there is generally a left-ear advantage for another type of auditory(听觉的) signal: music. When right-handed people listen to melodic patterns they report them better from the left ear.Which of the following would be the most proper title for the passage?
| A．An Introduction to Speech Damage in Patients with Brain Damage. |
| B．An Investigation into the Role of the Brain’s Hemispheres. |
| C．An Analysis of Left and Right-handed People. |
| D．An Examination of “Dichotic Listening”. |
The “dichotic listening” procedure could best be described as hearing _______.
| A．two different words in the same ear twice |
| B．the same word twice in the same ear |
| C．two different words in different ears |
| D．two different words twice in two ears |
according to the passage, right-handed people normally _______.
| A．have better hearing in their both ears |
| B．have little difficulty in reporting words given to their right ears |
| C．are unable to report word pairs given to their left ears |
| D．correctly report word pairs given in a row |
according to the passage, music is best appreciated when heard by _______.
| A．the left ear of right-handers |

Zipped into a bag, it looks like a large umbrella. Unfolded, it goes along the street like any other bicycle.
It's the "A-bike", the brainchild (脑力劳动的产物) of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the world's first pocket calculator. He described his new invention as "the world's smallest, lightest foldable bicycle".
"My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used,"said Sinclair.
The mini-bike, showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly US$300, is built for riders as heavy as 112 kilograms and is height-adjustable（可调整高度的）. It takes about 20 seconds to fold or unfold.
Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers per hour)," he said. Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters （立方米）.
Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years. The most important character of this kind of bike is its ________ .
| A．big size |
| B．light weight |
| C．beautiful appearance |
| D．foldable structure |
The wheels of a regular bicycle is ________ the size of this kind of bike.

| B．three times |
| C．one-fourth |
| D．one-third |
This kind of new bike is mainly made of ________ .
| A．plastic | B．packages | C．bags | D．metal |
The best title of the text is ________ .
| A．World's smallest foldable bicycle arriving |
| B．A new bike, a large umbrella |
| C．A foldable bike, a large bag |
| D．A great inventor of a new bike |
This kind of new bike hasn't been fixed with ________ .
| A．a wheel |
| B．an electric motor |

Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23.It was the third shark attack along the coast of Australia's largest city in a month.
The 15-year-old boy and his father were in the water off Avalon，on Sydney's northern beaches，around dawn when he was attacked.The city's beaches are packed with locals and tourists during the summer months.
“The father heard a scream and turned to see his son thrashing(激烈扭动)about in the water，”the police said.“Fortunately，the shark swam away and the boy was helped to the shore by his father.”
Lifesaving Club spokesman Nick Miller said，“It got him around the top of his left leg and the father came and dragged him out of water.”He said the boy was bleeding heavily when he was brought to the shore.“There was a lot of pain，as you can imagine.”The teenager was airlifted to hospital for treatment for leg injuries.
Police said the bites “cut through to the bone”，but the boy did not appear to have sustained any fractures (骨折)．He was in a stable condition now.
Several beaches were closed after the attack.Water police and lifeguards were searching for the shark，while the police hoped to identify its species by the shape of the bite marks.But they said it was too early to say what type of shark attacked the boy.“I don't even know if he saw it，”Miller said.
Many shark species live in the waters off Sydney's beaches，but attacks on humans are still relatively rare.However，there were two attacks on successive days earlier this month，one on a navy diver in Sydney harbor，not far from the famous Opera House，and the other on a surfer at the city's world-famous Bondi beach.
Fishermen say shark numbers are on the rise.There is a ban on commercial fishing in the harbor，which has increased fish stocks.Marine experts also claim environmental protection has created a cleaner environment，attracting sharks closer to the shore as they chase fish.Many shark species，including the Great White—the man-eaters made famous in Steven Spielberg's Jaws—are protected in Australian waters.The report mainly tells us ________.
| A．shark attacks on humans are on the rise |
| B．sharks attacked humans three times in one month |
| C．a boy was attacked by a shark at a Sydney beach |
| D．shark numbers are increasing in the waters off Sydney's beaches |
The underlined word “savaged” in the first paragraph probably means “________”．
| A．attracted | B．dragged | C．bit | D．packed |
What do we know about the city of Sydney from the passage?
B．Sydney harbor is not far from the famous Opera House.
C．There are many locals and tourists on its coast all the year round.

Who are these people rushing by you in the street? More than 215 million people now call America “home”, but most of them can trace their families back to other parts of the world. If you look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States, have lost the customs and cultures of their original countries and have become “American” is really not true. In fact, what exists in America is more often a kind of “side-by-side” living in which groups of people from other countries often have kept many of their customs and habits. They join the general American society only in certain areas of their lives—such as in schools, business, and sports—but they keep many of their own native customs and manners socially and at home. This living “side-by-side” has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas and dress, food, and social customs in America. Everyone can find some part of his or her familiar world in the United States, in churches, music, food, national groups, or newspapers.More than 215 million people call America “home” because_______.
