　　Oil prices dropped more than 7％ after Western nations released the biggest amount of oil from their emergency strategic stocks(战略储备油)since 1991, in a warning shot aimed at OPEC, the oil producers' cartel(同业联盟)．

　　The International Energy Agency(IEA)agreed to release 60 million barrels of oil in the coming month to offset ________ the daily production loss of 1.5 million barrels of high quality oil from Libya(利比亚)．

　　The US led the release, providing 50％ of the oil, with Japan, Germany, France, Spain and Italy providing most of the rest．The IEA said that it was in consultations(磋商)with China, the world's second-largest oil consumer but declined to say whether Beijing would join the effort．

　　Brent oil prices dropped 7.4％ to＄105.72 after the news was released, before settling at ＄106.12 in late afternoon trade in London on June 23．

　　The move is only the third time in the history of the IEA, established in 1974 as a counterbalance to OPEC after the Arab oil crisis： Western governments are concerned about the impact of high oil prices on the economic recovery．

　　"Greater tightness in the oil market threatens the fragile global economic recovery, " the IEA warned．

　　Steven Chu, US a energy secretary, said "we are taking this action in response to the ongoing loss of oil due to supply decrease in Libya and other countries and their impact on the global economic recovery．"

　　"As we move forward, we will continue to monitor the situation and stand ready to take additional steps if necessary．" The US special oil reserve is currently at a record high level of 727million barrels．

　　Earlier this month, OPEC members failed to agree an official increase in production quotas despite a concerted effort by Saudi Arabia, the world's biggest producer and traditionally seen as the OPEC leader, to boost output．Iran opposed the increase．Iran's OPEC governor argued that there was no evidence of a supply shortage．

　　The IEA said in May that it would use all tools at its disposal to increase supply unless the cartel raised production．

　　Some experts feel that cars are certain to fall into disuse．They see a day in the not-too-distant future when all cars will be deserted and made useless．Other experts, however, think the car is here to stay．They hold that the car will remain a leading means of city travel in the foreseeable future．

　　The car will undoubtedly change greatly over the next 30 years．It should become smaller, safer, and more practical, and should not be powered by the gas engine．The car of the future should be far more pollution-free than present types．

　　Unless changes take place in the power system, the car in the future will still be the main problem in city traffic jams．One suggested solution to this essential problem is the automated(自动的)system, which seems to hold water．

　　When the car enters the highway system, a small arm will drop from the car and connect with a rail, which is similar to those powering subway trains electrically．Once joined to the rail, the car will become electrically powered from the system, and control of the car will pass to a central computer．The computer will then monitor all the car's movements．The driver will use the telephone to dial instructions about his position and the place he heads for into the system．The computer will find the best way and reserve space for the car all the way to the correct exit from the highway．The driver will be free to relax and wait for the call that will warm him of his coming exit．It is believed that an automated highway will be able to deal with 10, 000 cars per hour, compared with the 1, 500 to 2, 000 cars that can be carried by a present-day highway．

　　The Scottish teacher who received it in class had no idea what the girl who wrote it meant．The essay was written in a form of English used in cell phone text messages．Text messages(also called SMS2)through cell phones became very popular in the late 1990s．At first, mobile phone companies thought that text messaging would be a good way to send messages to customers, but customers quickly began to use the text messaging service to send messages to each other．Teenagers in particular enjoyed using text messaging, and they began to create a new language for messages called texting．

　　A text message is limited to 160 characters, including letters, spaces, and numbers, so messages must be kept short．In addition, typing on the small keypad of a cell phone is difficult, so it's common to make words shorter．In texting, a single letter or number can represent a word, like “r” for “are,” “u” for “you,” and “2” for “to．” Several letters can also represent a phrase, like “lol” for “laughing out loud．” Another characteristic of texting is the leaving out of letters in a word, like spelling “please” as “pls．”

　　Some parents and teachers worry that texting will make children bad spellers and bad writers．The student who wrote the essay at the top of this page said writing that way was more comfortable for her．(The essay said, “My summer holidays were a complete waste of time．Before, we used to go to New York to see my brother, his girlfriend, and their three kids face to face．”)

　　Not everyone agrees that texting is a bad thing．Some experts say languages always evolve, and this is just another way for English to change．Other people believe texting will disappear soon．New technology for voice messages may soon make text messages a thing of the past．

　　Some people argue that the pressures on international sportsmen and sportswomen kill the essence(本质)of sport-seeking for personal excellence．Children kick a football around for fun．When they get older and play for local school teams, they become competitive but they still enjoy playing．A single person's representing his country cannot afford to think about enjoying himself; he has to think only about winning．He is responsible for an entire nation's hopes, dreams and fame．

　　A good example is the football World Cup．Football is the world's most important sport．It is even more important now that the United States is seriously taking it up．Winning the World Cup is perhaps the greatest of international sporting success．Mention “Argentina” to someone and the chances are that he'll think of football．In a sense, winning the World Cup “put Argentina on the map”．

　　Sports fans and supporters get quite irrational(失去理性的)about the World Cup．People in England felt that their country was somehow important after they won in 1996．Last year thousands of Scots sold their cars, and even their houses and spent all their money traveling to Argentina where the finals were played．

　　So am I arguing that international competition kills the idea of sports? Certainly not! Do the Argentineans really believe that because eleven of their men proved that most skillful at football, their nation is in every way better than all others? Not really．But it's known that you won, and that in one way at least your country is best．

　　It feels like every time my mother and I start to have a conversation, it turns into an argument．We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War 3．She'll talk about my lack of bright future because I don't plan to be a doctor．And much to her disappointment, I don't want to do any job related to science, either．In fact, when I was pushed to say that I planned to major(主修)in English and communications, she nearly had a heart attack．

　　“Why can't you be like my co-worker's son?” she bemoans all the time．Her coworker's son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer．I don't know what to answer except that I simply can't be like Mr．Perfect as I've called the unnamed co-worker's son．I can't be like him．I am the type of the person who loved to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of a fame or salary．

　　I understand why my mother is worried about my future major．I've seen my mother struggle to raise me on her small salary and work long hours．She leaves the house around 6:30 am and usually comes home around 5 pm or even 6pm．However, I want her to know that by becoming a doctor, it doesn't mean I'll be successful．I'd rather follow my dreams and create my own future．

　　My life suffered a lot in summer five years ago．My father died in a car accident，leaving my mother，my two younger brothers and I alone．At that time，I was a senior high school student．After my father's funeral，I had no choice but to drop out of school and work in a factory．

　　I really wanted to return to school and wanted to go to college，but I couldn't．I only hoped to bring up my two young brothers．Life was not easy for me，for I couldn't afford their tuition even if I worked from day to night without stopping．Without my father's protection，I thought I was a slave to the fate．

　　Later on，something changed my life．I still remember that it was a rainy day．I put myself in the rain and walked slowly in the street．

　　Suddenly the rain stopped！I raised my head and found “the sky” was in fact a dark blue umbrella．Then I noticed a middle-aged man with one leg on crutch(拐杖) standing behind me．He said to me，“Why not run without an umbrella？If you didn't run，you would get drenched．”

　　The man told me that he was a promoter．He once dreamed of being a policeman，but an accident ruined his dream．Though his present job was not suitable for his legs，it was a wonderful start to him．He was very happy that he didn't lose heart and still “ran” on the road of life．．．

　　I was encouraged by the man's words．I went to a big city and became an assurance representative．After two years'running，I did well and my family condition turned better little by little．Later I returned to school and succeeded in my entrance to university．

　　Life is like this．When you are in rainy days in your life，if you couldn't find a way to prevent you from being wet，you would be overwhelmed．But if you decide to get rid of it，you'll discover that the rainy days last not so long as you imagine．

　　Donald had his own difficulties in sleeping that night．Not just because of the bright lights of the shelter or people's constant voices, it was the happening repeatedly nightmare that caused him to stay awake, to fear sleep．Donald was back in his small house．He did his best to ignore the howling winds outside his window．Yet he could not turn out the fearful whimpers (呜咽) of his little dog, or the uncomfortable sounds of his mother anxious in her room next door, unable to sleep through the storm despite her insistence they would be all right．

　　Donald did not want his mother to be upset, but on some level, he was glad to hear she was awake, It meant he was not alone in the dark．Though he was 12, until recently it was impossible for Donald to fall asleep unless his mother lay down by his side．

　　Suddenly there was a crash．Their living room window is shattered (打碎) by 125 miles an hour winds．Troy rushed to Donald and sat anxiously on the edge of his bed．He did his best to calm his mother, and she had to comfort him．Soon water was seeping (渗入) into the single floor house．Quickly it rose from ankle level to leg level．At Donald's insistence, they pushed their way through the water --- now chest high --- toward the front door．When they fought their way into the living room, water rose to their chins．

　　It was a struggle for the boy and mother to stay afloat．In a total panic, desperate to hold on to something, Troy caught a curtain rod．She was breathing hard, shouting that she couldn't swim．

　　Donald cried out, “Mom! Hold on!” Just then Donald also caught a floatable wood board．

　　Did you ever look up at the moon and think you saw a man's face there？When the moon is round and full，the shadows of the moon mountains and the lines of the moon valleys sometimes seem to show a giant nose and mouth and eyes．At least，some people think so．

　　If there were a man on the moon－instead of mountains and valleys that just look like the face of a man－what would he be like?

　　He would not be like anyone you know．He would not be like anyone anybody knows．

　　If the man on the moon were bothered by too much heat or cold the way Earth people are，he could not stay on the moon．

　　The moon becomes very，very hot．It becomes as hot as boiling water．And the moon becomes very，very cold．It becomes colder than ice．

　　Whatever part of the moon the sun shines on is hot and bright．The rest of the moon is cold and dark．

　　If the man on the moon had to breathe to stay alive，he couldn't live on the moon because there's no air there．(He'd have to carry an oxygen tank，as astronauts do．)There's no food on the moon，either．Nothing grows－not even weeds．

　　If the man on the moon liked to climb mountains，he would be very happy．There are many high places there，such as the raised land around the holes，or craters，of the moon．Some of these rims are as tall as Earth's highest mountains．

　　But if the man on the moon liked to swim，he would be unhappy．There is no water on the moon－just dust and rock．

　　When you think of what it's like on the moon，you may wonder why it interests our scientists．One reason is that the moon is Earth's nearest neighbor－it is the easiest place in space to get to．

　　Going back and forth between the moon and Earth，astronauts will get a lot of practice in space travel．Things learned on moon trips will be of great help to astronauts who later take long，long trips to some of the planets．

　　Scientists are also interested in the moon because it has no air．The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes．A telescope on the moon would give them a clearer，closer view of the stars．

　　In the past decade the popularity of rock climbing has greatly increased，and so has the number of injuries．It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year．Study findings revealed a 65 percent increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2008．

　　The study，published in the online issue of the American Journal of Preventive Medicine，found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2008．The most common types of rock climbing-related injuries were fractures (骨折) and sprains (扭伤)．The ankle was the most common body part to be injured (40 percent)．Climbers in the study ranged in age from 2 to 74，with an average age of 26．The study also found that women took up a quarter of the injuries．

　　Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall．The severity of fall-related injuries had a lot to do with the height of the fall．Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower．

　　“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury，” explained the study author Lara McKenzie，PhD，director at the Center for Injury Research and Policy at Nationwide Hospital．“This trend，combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries，demonstrates the need to increase injury prevention efforts for climbers．”
