It is sometimes said that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects (UFO). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report.
Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night.
“It wasn’t the moon ”, was the reply.
They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn’t smoke because it didn’t change its shape. It was moving in a regular way. That is to say, it didn’t go suddenly faster or more slowly, and it didn’t go higher or lower. So the two men decided that there must be men in it.
After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness.
When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast.
On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken?

Cities need to put efforts to deal with pollution and clear the air.
Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015，according to the latest plan released by the State Council.
Besides the existing pollution control program for CO2，regional emission caps(区域排放上限) for other certain chemicals will be established in the three key air polluting areas—the Yangtze River Delta，Pearl River Delta and the Beijing-Tianjin- Hebei region. Coal-consumption caps will also be tried out in some areas，according to the plan.
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people’s health，Zhang Lijun，viceminister of environmental protection，said in an interview on Monday.
The air quality in a city affects the areas nearby because pollutants can travel in the sky，said Chai Fahe，vice-director of Chinese Research Academy of Environmental Sciences.
“So efforts to reduce air pollution in a single city，targeting a certain pollutant(污染物) will not be enough，” Chai said.
Zhang said the country’s major industrial districts—the Yangtze River Delta，Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years.
These three regions，home to at least 200 million people，occupy only 6.3 percent of the country’s area but consume 40 percent of the country’s coal and produce half of its steel，according to official figures.
Studies also show that the visibility(能见度) in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s，as a result of air pollution.
Liaoning province，the Shandong Peninsula，Wuhan in Hubei province and its surrounding area，the Changsha-Zhuzhou-Xiangtan region in Hunan province，the Chengdu-Chongqing region，and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs，according to the plan.
The new plan also requires an improved air quality system，which will measure the pollution levels. “The current system，which only measures some major pollutants，cannot reflect the_truepicture.” said Chai.
【小题1】It will not be enough to reduce air pollution in a single city because ________.
| A．air pollution has been becoming more and more serious in recent years |
| B．air pollution like acid rain and smog is threatening people’s health |
| C．air pollutants in a city can travel in the sky and affect nearby areas |
| D．air pollutants stay in fixed places over the cities |
| A．123 to 115 km | B．137 to 145 km |
| C．123 to 145 km | D．115 to 137 km |
| A．to inform readers of the damage caused by air pollution |
| B．to introduce the new plan to control air pollution |
| C．to provide official figures of air pollution levels |
| D．to point out the regions affected by air pollution |
| A．The major pollutants. |
| B．The key polluted areas. |
| C．The major polluted cities. |
| D．The pollution levels. |
NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people’s memories are affected.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war.
They say that there are many people who suffer from terrible memories.
"Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
But those who are against the research say that maybe the pills can change people’s memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past.
"All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.
1.The passage is mainly about .
A. a new medical invention
B. a new research on the pill
C. a way of wiping out painful memories
D. an argument about the research on the pill
2.The drug tested on people can .
A. cause the brain to fix memories
B. stop people remembering bad experiences
C. prevent body producing certain chemicals
D. wipe out the emotional effects of memories
3.We can infer from the passage that .
A. people doubt the effects of the pills
B. the pill will certainly stop people's emotional memories
C. taking the pill will do harm to people's physical health
D. the pill has already been produced and used by the public in America
4.Which of the following does Rebecca Dresser agree with in the last paragraph ?
A. some memories can ruin people's lives.
B. people want to get rid of bad memories.
C. experiencing bad events makes us different from others.
D. the pill will reduce people's sufferings from bad memories.
“Mum, what does it mean when someone tells you that they have a skeleton（骨骼）in the closet（衣橱）?” Jessica asked. “A skeleton in the closet?” her mother paused thoughtfully. “Well, it’s something that you would rather not have anyone else know about. For example, if in the past, someone in Dad’s family had been arrested for stealing a horse, it would be ‘a skeleton in his family’s closet’. He really wouldn’t want any neighbor to know about it.”
“Why pick on my family?” Jessica’s father said with anger. “Your family history isn’t so good, you know. Wasn’t your great-great-grandfather a prisoner who was transported to Australia for his crimes?” “Yes, but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.” “Gosh, sorry I asked. I think I understand now,” Jessica cut in before things grew worse.
After dinner, the house was very quiet. Jessica’s parents were still quite angry with each other. Her mother was ironing clothes and every now and then she glared at her husband, who hid behind his newspaper pretending to read. When she finished, she gathered the freshly pressed clothes in her arms and walked to Jessica’s closet. Just as she opened the door and reached in to hang a skirt, a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor. Jessica’s mother sank in a faint（晕倒）, waking only when Jessica put a cold, wet cloth on her forehead. She looked up to see the worried faces of her husband and daughter.
“What happened? Where am I?” she asked. “You just destroyed the school’s skeleton, Mum,” explained Jessica. “I brought it home to help me with my health project. I meant to tell you, but it seemed that as soon as I mentioned skeletons and closets, it caused a problem between you and Dad.” Jessica looked in amazement as her parents began to laugh madly. “They’re both crazy,” she thought.
【小题1】According to Jessica’s mother, “a skeleton in the closet” means ______.
| A．a family honor | B．a family secret |
| C．a family story | D．a family treasure |
| A．They were brought to Australia as prisoners. |
| B．They were the earliest people living in Australia. |
| C．They were involved in some crimes in Australia. |
| D．They were not regarded as criminals in their days. |
| A．She was curious about it. | B．She planned to keep it for fun. |
| C．She needed it for her school task. | D．She intended to scare her parents. |
| A．they were crazy |
| B．they were over excited |
| C．they realized their misunderstanding |
