In many businesses, computers have largely replaced paperwork, because they are fast, flexible, and do not make mistakes. As one banker said, "Unlike humans, computers never have a bad day." And they are honest. Many banks advertise that their transactions are "untouched by human hands" and therefore safe from human temptation. Obviously, computers have no reason to steal money. But they also have no conscience, and the growing number of computer crimes shows they can be used to steal.
Computer criminals don't use guns. And even they are caught, it is hard to punish them because there are no witnesses and often no evidence. A computer cannot remember who used it: it simply does what it is told. The head teller at a New York City Bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this theft because he moved the money from one account to another. Each time a customer he had robbed questioned the balance in his account, the teller claimed a computer error, then replaced the missing money from someone else's account. This man was caught only because he was a gambler. When the police broke up an illegal gambling operation, his name was in the records.
Some employees use the computer's power to get revenge on employers they consider unfair. Recently, a large insurance company fired its computer-tape librarian for reasons that involved her personal rather than her professional life. She was given thirty days' notice. In those thirty days, she erased all the company's computerized records.
Most computer criminals have been minor employees. Now police wonder if this is "the tip of the iceberg". As one official says, "I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing—the ones who really know how a computer works."Which feature of computers makes computer theft possible?
A.They are fast, flexible and accurate. |
B.They usually function normally. |
C.They have no sense of what is right or wrong. |
D.They are honest and have no reason to steal money. |

If cars had wings,they could fly and that just might happen, beginning in 2011.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car-plane, the Transition, to customers by the end of 2012.
“It’s the next ‘wow’ vehicle,”said Terrafugia vice president Richard Gersh.“ Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car plane has wings that unfold for flying—a process the company says takes one minute—and fold(折叠) back up for driving. A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go. When you land, you fold up the wings and hit the road. There are no expensive parking fees because you don’t have to store it at an airport—you park it in the garage at home.
The car-plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(临界)conditions.
The Transition’s price tag: $194,000, But there may be additional charges for options like a radio, transponder or GPS. Another option is a full-plane parachute. “If you get into a very awful situation, it is the necessary safety option,” Gersh said.
So far, the company has more than 70 orders with deposits. “We’re working very closely with them, but there are still some remaining steps,” Brown said.We can learn from the first paragraph that.
A.car- planes will be popular in 2012 |

At first, the earth’s surface layer (层) was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles (卵石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks in the rock, which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces.
The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces.According to the passage, soil____________.
A.forms very slowly |
B.is a mixture of stones, pebbles and sand |
C.makes up the layers of the earth |
D.is becoming smaller and smaller |

B.If a large rock never moves, it will never break up. |
C.Even if a large rock never moves, it will break up. |
D.Ice in the cracks helps to break up rocks. |
The best title for this passage should be____________ .
A.Soil From Rocks |
B.Ways to Break up Rocks |

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid. It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.A good title for this reading passage is______.
A.Popeye the Sailor | B.The Truth About Spinach |
C.Mistake with Numbers | D.Folic Acid Makes You Strong |
Why did many people eat spinach after they saw Popeye the Sailor?
A.They thought spinach made them strong. |
B.They thought Popeye was funny. |

D.People liked folic acid. |
A research group told people that spinach______.
A.made Popeye strong |
B.was a green vegetable |
C.had less iron than other green vegetables |
D.had more iron than other green vegetables |
The reading passage says that perhaps Popeye got his strength from______.
A.iron | B.folic acid |
C.spinach | D.exercise |
Folic acid is ______.
A.something in food | B.a vegetable |
C.dangerous | D.a certain kind of spinach |
In the summer of 1978 an English farmer was driving his tractor through a field of wheat when he discovered that some of his wheat was lying flat on the ground. The flattened wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. The five circles were in a formation like five dots. During the following years, farmers in England found the strange circles in their fields more and more often.
The circles are called “crop circles” because they appear in the fields of grain ― usually wheat or corn. The grain in the circles lies flat on the ground but is never broken; it continues to grow, and farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September.
At first, people thought that the circles were a hoax. Probably young people were making them as a joke, or farmers were making them to attract tourists. To prove that the circles were a hoax, people tried to make circles exactly like the ones that farmers had found. They couldn’t do it. They couldn’t enter a field of grain without leaving tracks, and they couldn’t flatten the grain without breaking it.
Many people believe that beings from outer space are making the circles to communicate with us from far away and that the crop circles are messages from them.
Scientists who have studied the crop circles suggested several possibilities. Some scientists say that a downward rush of wind leads to the formation of the circles — the same downward lash of air that sometimes causes an airplane to crash. Other scientists say that forces within the earth cause the circles to appear. There is one problem with all these scientific explanations: crop circles often appear in formations, like the five-dot formation. It is hard to believe that any natural force could form those.In the summer of 1978, an English farmer discovered in his field that ______.
A.some of his wheat had been damaged |
B.some of his wheat had fallen onto the ground |
C.his grain was growing up in circles |
D.his grain was moved into several circles |

Which of the following may prove that the crop circles are not made by man?
A.The farmers couldn’t step out of the field. |
B.The farmers couldn’t make the circles round. |
C.The farmers couldn’t leave without footprints. |
D.The farmers couldn’t keep the wheat straight up. |
One explanation given by scientists for the crop circles is that they are made by _____.
A.airplane crashes | B.air movement |
C.unknown flying objects | D.new farming techniques |
