UFO stands for "unidentified flying object"(不明飞行物). Many people reported having seen UFOs in the sky. A lot of countries tried to research them and in 1952 they got the name of UFO.

There were several reports published in the 19th century which were related (相关的) to UFOs. Denison Daily News in its report of 25th January, 1878 wrote that a farmer, Martin, saw a flying object in the sky and it was just like a plate. This was the first time that the word plate had been related to the UFOs.

The first reports on UFOs came during World War II. In 1947 pilot Kenneth Arnold said while he was flying near the Mount Rainer he saw a very bright object in the sky. He said that it was like a plate too. The information given by Kenneth got lots of attention from the media and people.

Several research organizations gave their reports on the UFOs. They showed direct or indirect physical evidence of the UFOs, and sometimes UFOs’appearance was found on the radar (雷达) screen. Many people tried to take video tapes or photos of the UFOs as proof. Most UFOs are in saucer shape while many UFOs are like a cigarette or a half ball.

Many films and TV shows are made about UFOs. There are two famous movies which are created on the theme of UFOs and aliens, War of the Worldand Star Wars. UFOs have created a new field in science which is known as Ufology (飞碟学).

People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.

The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding （繁殖） rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”

The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.

It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.

The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.

While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical （等级的） societies remain stable.

The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”

Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.

The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.

Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety－five would have the same effect.

Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales（鲸鱼）.

A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.

The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected(被感染的).

Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.

Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists don’t think that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.

1.According to the passage, which of the following is increasingly dangerous to sea creatures?

A. The sound of cars. B. The sound of voices.

C. Man-made noise pollution. D. The sound of steps.

2.According to the passage, natural sounds include all of the following EXCEPT________.

A. sounds made by animals themselves B. ocean drilling

C. underwater earthquakes D. the breaking of ice fields

3.Which of the following is discussed in the third paragraph?

A. The same noise level produces a different effect on land and in the ocean.

B. Different places may have different types of noises.

C. The decibel is not a right unit (单位) for measuring underwater noise.

D. Different ocean animals may have different reactions to noises.

4.Which of the following is true of whales?

A. They won't be confused by noises.

B. They are deaf to noises.

C. Their ability to reproduce will be lowered by high-level noises.

D. Their hearing will be damaged by high-level noises.

5.According to the passage, what will scientists most probably do in the future?

A. They will work hard to reduce ocean noise pollution.

B. They will protect animals from harmful noises.

C. They will try to set a limit of 120 decibels.

D. They will study the effect of ocean noise pollution.

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.

"Women tend to be social in their behavior. They often share with others. But men lend to be competitive. They are trying to improve their social status," said Professor Ryan.

Generally, people believe that the hormone oxytocin is let out in our body in various social situations and

our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.

But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.

Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants（参与者）received oxytocin. The other half received placebo (安慰剂).

After a week, the two groups switched with participants. They went through the same procedure with the other material.

Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.

The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.

Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal."

1.What causes men and women to behave differently according to the text?

A. Placebo B. Oxytocin C. The gesture D. The social status

2.What can we learn from Professor Ryan's previous experiment?

A. Oxytocin affects our behavior in a different way.

B. Our body lets out oxytocin when we are deep in love.

C. Our body produces oxytocin when we feel unhappy about others' success.

D. Oxytocin improves our abilities to understand people's behavior differences.

3.Why did Professor Ryan conduct the recent experiment?

A. To test the effect of oxytocin on the ability to recognize social interactions.

B. To know the differences between friendship and competition.

C. To know people's different abilities to answer questions.

D. To test people's understanding of body language.

4.The author develops the text by______.

A. explaining people's behaviors

B. describing his own experiences

C. distinguishing sexual differences

D. discussing research experiments
