Some byproducts of this process are called “greenhouse” gases, the most important one of 3. is carbon dioxide. Dr Janice Foster explains: “There is a natural phenomenon that scientists call the ‘greenhouse 4. ’ (effective). This is 5. small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour trap heat from the sun and 6. warm the earth. 7. the ‘greenhouse effect’, the earth would be about thirty-three degrees Celsius 8. (cool) than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends 9. (trap) in the atmosphere 10. (cause) the global temperature to to up.”

Do you have memories of being kidnapped (绑架)by aliens (外星人) and taken away rapidly in a spaceship? You wouldn’t be alone. Several thousand people worldwide reported to have had such experiences, researchers say. But in a new study, a psychology expert at London’s Goldsmiths College says these experiences are proof of the weakness of the human memory, rather than evidence of life in outer space.

“Maybe what we’re dealing with here is false memories, and not that people are actually being kidnapped and taken aboard spaceships,” says Professor Chris French, who surveyed 19 so-called victims.

Several of the victims reported being taken away from their beds or cars by alien creatures around four feet high, with long and lean arms and legs and oversized heads, French said. Some men said they were forced to take painful medical examinations by the aliens.

Many of the alien experiences could be explained by sleep paralysis, a condition in which a person is awake and aware of the surroundings but is unable to move. Sleep paralysis often leads to hallucinations —the experience of seeing or feeling something that is not really there and 40 percent of people experience the state at least once in their lives, French said. A rich imagination was also at play. Several of the alien victims were more likely to fantasize and reported to have seen ghosts (幽灵) and have unnatural abilities.

“People have very rich fantasy lives,” said French, who is due to present his findings at a public seminar at London’s Science Museum on Wednesday. “So much that they often mix up what’s happening in their heads with what is going on in the real world.”

It was 7:00 am in Kyoto, Japan, and the taxi company had just called a second time to say they couldn’t find my house. Once again I spelt out directions even a blind person could follow. I glanced impatiently at my watch, and waited. Only two hours remained until my flight left—and it was an hour and a half trip to the airport.

Outside, heavy rains were pouring down. My house was so far north in the city that buses pass only here times a day.

The telephone rang again. “Terribly sorry,” began the man at the taxi company. Then I realized that the taxi company, flooded with calls, could only offer in-city runs. I had heard this happens when the weather gets bad. I shouted into the phone that I had a plane to catch and I would meet the taxi outside my house.

Standing in the wind-driven rain, I looked up and down the road. No taxi. A car went by, the driver and passenger staring at the crazy foreigner in the downpour.

Finally a white car appeared and pulled to a stop. A young man threw open the door, waving for me to get in. Shaking with cold and anger, I climbed in.

In the most polite Japanese, the man said he was called Mike, with who I had spoken three times that morning. He had left his post in the office and raced here in his personal car. He apologized again, but didn’t explain why a taxi would not pick me up. Delivering me straight to the airport, he refused the 2,000 yen I pressed into his hand.

A few hours later, as the storm-delayed 727 took off, I opened the newspaper. On the second page my eyes caught the headline of a short article: Taxi Strike Begins This Morning in Kyoto.

1.Why did the writer call a taxi early in the morning?

A. He wanted to catch a plane.

B. He as unable to find the airport.

C. There were few taxis in town.

D. All the buses stopped because of the rain.

2.What was the reason for the taxi company not being able to pick him up?

A. More people were riding in taxis on rainy days.

B. The writer didn’t give the correct address.

C. The taxi drivers refused to work.

D. The taxi drivers didn’t like to drive long distance.

3.The writer got to the airport ____________.

A. by riding in Mike’s car from the taxi company

B. with the help of Mike from the post office

C. by getting a lift in a passing car

D. with the help of a taxi driver sent by his company

4.We can learn from the text that the driver was _____________.

A. quick-minded at taking action

B. a self-employed driver

C. unwilling to drive to the airport

D. warm-hearted toward people
