While your pet fish may appear to be ignorant of your presence, chances are that it knows you extremely well and can probably even identify you from a crowd of human faces! At least, that is the conclusion reached by scientists the University of Oxford in the U.K. and the University of Queensland in Australia, following an extensive study of the archerfish (喷水鱼), a species of tropical fish that can be found all the way from India to Indonesia, the Philippines, and Australia.

The ability to distinguish between human faces is a complex task. That’s because we all have the same basic features — two eyes sitting above a nose and a mouth. It’s only the subtle differences that make humans distinct from one another. Since this requires a combination of both visual sense and memory, researchers had always assumed that it was a skill possessed only by those with complicated brains, i.e., humans, a few select animals — such as horses, cows, dogs, monkeys and some birds, like pigeons.

To test if this assumption was accurate, a team of scientists led by Dr. Cait Newport, Marie Curie Research Fellow in the Department of Zoology at Oxford University, decided to study fish. The aquatic (水生的) animals have small brains that lack the neocortex(大脑新皮层), or neocortex-like structure, believed to help recognize the subtle differences between human facial features.

The team began by presenting four archerfish with images of two human faces. Initially, the fish spat randomly at both. However, they soon learned that pouring water at the one selected by the researchers earned them a food treat. After that, they focused primarily on that image. The researchers then took the experiment one step further, by introducing 44 other human faces to the mix.

To the researcher’s astonishment, the trained archerfish were able to recall the learned image almost 81% of the time. And this accuracy improved to 86% when the researchers made the identification even harder, by replacing the colored photos with a set of black and white images and hiding the shape of the head.

Telepathy (心灵感应) is the ability to communicate without the use of the five senses. It's an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct,we're using resources within the unconscious (潜意识的) mind. When the resources of two persons' unconscious minds link together into the same frequency (频率),we call it telepathy.

We can either send or receive telepathy. If you know who is calling before you answer the ringing phone,you are probably a good receiver. If you think of a person and he/she calls you,you are most likely to be better at sending.

You can easily put your ability to the test. Thinking of somebody and wish him or her to contact you. Be patient. The other person may not be a good receiver,but they should contact you much earlier than would normally be expected. Or whenever the phone rings,try ‘feeling’ who is contacting you. Don't guess,but try to feel it with your mind. However,if neither of these works for you,that doesn't mean that you have no ability of telepathy. As mentioned earlier,telepathy is most likely to turn up in case of emergency.

Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams have a clear connection. These people are probably linking to each other's unconscious mind.

Telepathy & relationship. The more people spend time together,the more likely they are to be able to link up to the other's mind,especially when separated. There are two reasons for this. One is that they understand the other's mind through time spent together;the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child's eagerly wanting his or her mother,knowing that this is the person who would always want to be there for them,and the mother's deep desire to protect her child from harm.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

1. But still there is a danger that grows every year.Airliners get larger. Some airplanes can hold over 300 passengers. And the air itself becomes more and more crowded. If one giant airliner crashed into another in mid-air 600 lives could be lost. 2. Air traffic controllers tell the pilot exactly when to turn when to climb and when to come down.The air traffic controllers around a busy airport like London-Heathrow may handle 2500 planes a day.Not all of them actually land at the airport.Many plane that flies near the airport comes under the orders of the controllers there. 3. Recently such a disaster almost happened. 4. One with 69 passengers had come from Toronto and the other with 176 passengers from Chicago, an air traffic controller noticed on his radar screen that the two planes were too close to each other. He ordered one to turn to the right and to climb. But he made a mistake. He ordered the wrong plane to do this. Fifteen seconds later it flew directly in front of the second plane. They avoided each other by the smallest part of a second. The distance between them was less than that of a large swimming pool. 5.

A. Even a small mistake on their part could cause a disaster.

B. Two large jets were flying towards the airport.

C. Nowadays people like traveling more by air than by car.

D. Today air travel is far safer than driving a car on a bus motor-way.

E. This is an example of the danger that grows every year.

F. In a word air travel is more dangerous we should choose others.

G. From the moment an airliner takes off to the moment it lands, every movement is watched on radar screen.
