Damage to Ozone Layer Gets Worse
In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer．The warning: The sun's summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported
to the United Nations that a layer of ozone（臭氧层）in the atmosphere, which protects humans from harmful levels of ultraviolet（紫外线）radiation, will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach Earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter．The hole was caused in chemicals used in refrigerators and air conditioners．When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica．Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone-destroying chemicals, the new findings are expected to advance the timetable for a total ban of the chemicals.The scientists have observed the ozone layer ______．
| A．since 1980 | B．since last winter |
| C．for more than 20 years | D．for about one year |
The ozone layer in the atmosphere can ______.
| A．do a lot of good to human beings in many ways |
| B．protect humans from diseases caused by bad weather |
| C．do a lot of harm to human beings in the summer-time |
| D．protect humans from harmful levels of ultraviolet radiation |
Scientists first found that there was a hole in the ozone layer ______.
| A．above Arctic during the winter in the mid-1980s |
| B．above Antarctica during the winter in the mid-1980s |
| C．over somewhere in the north of the equator in 1980 |
| D．over the USA in the summertime in the mid-1980s |
The damage to the ozone layer was caused by ______.
| A．the changeable weather | B．ozone-destroying chemicals |
| C．chemicals from refrigerators | D．chemicals from air conditioners |
A new chapter in space exploration has been opened up after NASA confirmed that their mission to bomb the Moon had found “significant quantities” of frozen water.Scientists said the “exciting” findings had gone “beyond expectations” as fully formed ice was found in a crater on the planet.The water was found in one mile high dust that was kicked up by the Lunar Crater Observation and Sensing Satellite(LCOSS) last month when it crashed into the Cabeus crater near the Moon's south pole.
“Indeed，yes，we found water.And we didn't find just a little bit，we found a significant amount，”said Anthony Colaprete，project scientist and principal investigator for the ￡49 million space mission.
“This is a great day for science and exploration，” said Doug Cooke，associate administrator of NASA.“The remarkable results have gone beyond our expectations.It is incredibly exciting.”
The identification of waterice is important for purely scientific reasons，but also because a supply of water on the Moon would be a vital resource for future human exploration. The findings，which completely contradict previous beliefs that the Moon was a dry place，justify the controversial mission. Over the last decade，scientists have found some hints of underground ice on the Moon's poles，mainly in the form of compounds of hydrogen but this is the best evidence yet.
The discovery is expected to have major implications for the future of lunar exploration，and a ready supply of water could help set up lunar bases or launch missions to Mars. Mr Colaprete said that it should be possible to purify the water for drinking even though it appeared to be mixed with poisonous methanol(甲醇)． Which of the following is TRUE of the “bombing”？
| A．It damaged the Moon surface severely. |
| B．It would do harm to the space environment. |
| C．It confirmed the existence of water on the Moon. |
| D．It would help the research on Mars. |
The underlined word “NASA” in the first paragraph maybe referred to ________.
| A．a base in space |
| B．a new kind of bomb |
| C．a part of the Moon |
| D．a government department |
Which of the following is the best title of the text?
| A．Water Found on the Moon after NASA “Bombing” |
| B．Unbelievable Space Research |
| C．Possible Base on the Moon |
| D．Mysterious Water Found on the Moon |

Albert was an ordinary worker in an oil company in America. His workmates gave a nickname(绰号) “Four dollars a bucket (桶)” to him, for he was always used to leaving an advertisement of his company “Four dollars a bucket of oil” below his name whenever and wherever he wrote down his name.
As time went by, people forgot his real name. Later, when Rockefeller, the board chairman of the oil company, heard of it, he was very surprised, so he invited Albert to come to his office.
“Some people give you a nickname for ‘Four dollars a bucket’. Why aren’t you angry?” asked Rockefeller with some puzzlement in his eyes.
“Oh! Mr. Rockefeller! I like this nickname very much, because ‘Four dollars a bucket’ is our company’s advertisement. As long as someone calls me ‘Four dollars a bucket’ once, I think it’s a free advertisement for our company. I have no reason to get angry. Don’t you think so, Mr. Rockefeller?”
“Oh! What a fantastic man!” Rockefeller said excitedly when hearing Albert’s words. “Young man, work harder! You must succeed in the future! I believe in you!”
Five years later, Albert became the second board chairman after Rockefeller.

阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。
If cars had wings，they could fly and that just might happen，beginning in 2011.The company Terrafugia，based in Woburn，Massachusetts，says it plans to deliver its carplane，the Transition，to customers by the end of 2011.
“It's the next ‘wow’ vehicle，” said Terrafugia vice president Richard Gersh.“Anybody can buy a Ferrari，but as we say，Ferraris don't fly.”
The carplane has wings that unfold for flying－a process the company says takes one minute－and fold back up for driving. A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies，although it is both. The company has been working with FAA to meet aircraft regulations，and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports：You drive the car to the airport and then you're good to go. When you land，you fold up the wings and hit the road. There are no expensive parking fees because you don't have to store it at an airport－you park it in the garage at home.
The carplane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds，including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under the bad weather instead of flying into marginal(临界的) conditions.
The Transition's price tag：$194,000.But there may be additional charges for options like a radio，a transponder or a GPS. Another option is a fullplane parachute.
“If you get into a very awful situation，it is the necessary safety option，” Gersh said.
So far，the company has more than 70 orders with deposits. “We're working very closely with them，but there are still some remaining steps，” Brown said.We can learn from the first two paragraphs that ________.
| A．carplanes will be popular in 2011 |
| B．people might drive a carplane in 2011 |
| C．both the Transition and Ferrari can take off and land |
| D．Richard Gersh is the vice president of Massachusetts |
It takes the carplane one minute to ________.
| A．fold and unfold its wings |
| B．unfold wings for flying |
| C．land in the airport |
| D．meet flying safety regulations |
According to the passage，which of the following is NOT true?
A．The carplane needs a runway to take off and land.
B．To meet aircraft regulations，the company has been working with FAA.
C．The carplane may fly as high as normal planes.
D．People can park the carplane in the garage at their home.The underlined word “it” in the last but one paragraph refers to ________.
| A．the radio |
| B．the transponder |
| C．the GPS |
| D．the fullplane parachute |
What's the best title for the passage?
| A．Cars with wings may be just around the corner |
| B．Which to choose：a Ferrari or a carplane? |
| C．A more convenient and cheaper way to fly |
| D．Cars with wings can fly as fast as planes |
