The summer beach season is prime time for shark attacks. It seems like sharks are attacking all the time. But that is something of an illusion. The number of attacks is very small.
How does a shark hunt? Muscles and fins give the shark its speed and maneuverability in the water. A shark’s front fins act like the wings of a plane and let it “fly” through the water. The tail acts like a high-power propeller
But the big thing that gives the shark its edge in the ocean is its sensory package. The package includes the shark’s eyes, ears, skin, nose and mouth, as weir as electric sensing.
A shark’s nose is probably its most important sense. If you were to put a single drop of blood in a swimming pool, a great white shark could smell that. And they can tell the direction that the smell is coming from.
Sharks handle their electric sensing using cell located in the head. Whenever something moves using its muscles, a shark can detect the electrical impulses flowing to those muscles. A shark can electrically “see” anything that has muscles even if it is hiding or the water is not clear.
Sharks even have vibration sensors in their skin. Even something moves near the shark, tubes pick up the pressure changes and hairs inside the tubes send signals to the brain. This extra sense allows a shark to turn quickly and attack again.
When you put all these different senses together , it makes the shark a nearly ideal hunter. A shark can detect prey from miles away and then use eyes, electrosensing and movement sensing to home in.
Strangely, sharks do not seem to use these senses to home in on people. The very low number of sharks tells us that sharks do not hunt people in a regular basis. On the other hand, people love to hunt sharks, Millions of sharks die every year. Without protection, extinction is a definite possibility.
68.From the text, we can know that_________________.
A. it is true that sharks are attacking all the time
B. a shark can see anything that has muscles even if it is hiding.
C. sharks deal with their electric sensing using cell located in the skin

Dog Translation Products Coming to U. S.
A Japanese toy maker declares that they have developed a gadget that translates dog barks into human language and plans to begin selling the gadget——under the name of Bowlingual——in U. S. pet stores and gift shops this summer.
Tokyo-based Takara Co. Ltd. says about 300, 000 of the dog translator gadgets have been sold since it was on sale in Japan late last year. It is forecasting far bigger sales once an English language translation for dogs comes to America in August. The United States is home to about 67 million dogs, more than six times the number in Japan.
"We know that the Americans love their dogs so much, so we don't think they will mind spending $ 120 on this product," the Takara marketing manager said during an interview at a recent pet products conference in Atlanta.
Regarded as one of the coolest inventions of 2002 by Time magazine, Bowlingual is made up of a 3 - inch long wireless microphone that is fastened to a dog collar and sends out sounds to a small console (控制臺) that is connected to a database (數據庫). The console divides each bark into six emotional types——happiness, sadness, disappointment, anger, threat and desire——and shows common phrases, such as "You're ticking me off," that fit the dog's emotional state.
Takara says it has spent millions of dollars developing the gadget in cooperation with famous sound experts and animal behaviorists.
One thing that does appear certain is that the markets for animal translation products will likely remain a dog's world since Takara has no plans to develop a similar gadget for cats. "They are too unpredictable (反復無常) , " the marketing manager said.
1.This passage mainly tells us that Bowlingual ___________.
A. was invented in Japan B. has developed quickly
C. will be sold in America D. sells well for its price
2.The underlined word "they" in the last paragraph refers to ___________.
A. markets B. products C. plans D. cats
3.When was this passage most probably published?
A. In the winter of 2002. B. In the spring of 2003.
C. In the summer of 2002. D. In the autumn of 2003.
4.From the passage, we can see that Takara Co. Ltd. is ___________ the sale of its new product.
A. proud of B. satisfied with
C. confident of D. worried about

第四部分閱讀理解（共15小題；每小題2分，滿分30分）
A
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(變平的) 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(構造) like five dots （點）. 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（交流）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 rush of air that sometimes causes an airplane to crash（墜毀）.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.
61. In the summer of 1978 , an English farmer discovered in his field that______.
A．some of his wheat had been damaged
B．his grain was growing up in circles
C．his grain was moved into several circles
D．some of his wheat had fallen onto the ground
62. According to the text, the underlined part “hoax” (line 1, para.3 ) probably means .
A．an action made to fool people
B．a special way to plant crops
C．a research on the force of winds
D．an experiment for the protection of crops
63. 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.
64. That the crop circles are made by is probably true.
A．air movement B．airplane crashes
C．new farming techniques D．unknown flying objects
