Language is a major problem for the European Union (EU). The agreement or treaty(条约) which created the organization that eventually became the EU, the Treaty of Rome, stated that each country's language must be treated equally. The original(原来的) six countries had only three languages between them: French, German and Dutch/Flemish. However, there are now 15 countries in the EU, with a total of 12 languages. EU documents must be translated into all these languages, and at official meetings the speeches must be translated into all the languages by interpreters.

All this translating is very expensive and time-consuming (费时的). It is said that nearly half of all employees of the EU are engaged in translating documents and speeches, and nearly half of the EU's administrative(管理方面的) costs are spent on this task. In the near future it is probable that several more

countries, most of them having their own languages, will join the EU, thus making the situation even worse.

The problem is not just cost; there are practical difficulties as well. With 12 languages, there are 132 possible "translation situations" that might be needed. It is often difficult to find people in the right place at the right time who can translate from (for example) Danish into Greek, or Dutch into Portuguese, at a high professional standard.

In practice the problem has been made less severe by the use of English in many contacts between EU officials, since almost all of them speak some English. However, any move to reduce the number of official languages (perhaps to four or five) would be a blow to the pride of the smaller Countries. Another commonly suggested solution is to make English the official language for all EU business. However, this is strongly resisted by powerful member countries like France and Germany.

Lead（铅） deposits, which accumulated（增加） in soil and snow during the 1960's and 70's, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated（托管） unleaded gas use in the United States, the lead accumulation world-wide has decreased greatly.
A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining（减少）.
In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasoline and thus enabled scientists to differentiate (分区) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.
In a study published in the journal Ambio, scientists found that lead levels in soil in the North-eastern United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period.
The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed (再分配)the lead faster than the scientists had expected. Scientists say both studies show that certain parts of the ecosystem (生态系统 ) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.
1. The study published in the journal Nature indicates that ________.
A. the Clean Air Act has not produced the desired results
B. lead deposits in arctic snow are on the increase
C. lead will stay in soil and snow longer than expected
D. the US is the major source of lead pollution in arctic snow
2. Lead accumulation worldwide decreased significantly after the use of unleaded gas in the US ________.
A. was discouraged B. was carried out by law
C. was forbidden by law D. was introduced
3. How did scientists discover the source of lead pollution in Greenland?
A. By analyzing the data published in journals like Nature and Ambio.
B. By observing the lead accumulations in different parts of the arctic area.
C. By studying the chemical elements of soil and snow in Northeastern America.
D. By comparing the chemical compositions of leaded gasoline used in various countries.
4. The authors of the Ambio study have found that ________.
A forests get rid of lead pollution faster than expected
B. lead accumulations in forests are more difficult to deal with
C. lead deposits are widely distributed in the forests of the US
D. the upper layers of soil in forests are easily polluted by lead emissions
5. It can be inferred from the last paragraph that scientists ________.
A. are puzzled by the mystery of forest pollution
B. feel ease by the use of unleaded gasoline
C. still consider lead pollution a problem
D. lack enough means to combat lead pollution

“Whatever”，totally tops most annoying word in the poll(民意测验).So, you know, it is what it is, but Americans are totally annoyed by the use of “whatever，，in conversations. The popular term of indifference(不感兴趣)was found most annoying in conversations by 47 percent of the Americans surveyed in a Marist College poll on Wednesday.
"Whatever" easily beat out “you know," which especially annoyed a quarter of interviewers. The other annoying expressions were "anyway"(at 7 percent), “it is what it is’，(11percent) and “at the end of the day”(2 percent).
"Whatever" is an expression with staying power. It left everyone a deep impression in the song by Nirvana (“oh well, whatever, never mind”）in 1991 and was popularized by the Valley Girls in the film “Clueless”，later that decade. It is still commonly used, often by younger people.
It can be a common argument-ender or a signal of indifference. And it can really be annoying. The poll found '"whatever" to be consistently(始终地)disliked by Americans regardless of their race, sex, age, income or where they live.
“It doesn't surprise me because ‘whatever，is in a special class, probably，，，said Michael Adams, author of “Slang(俚语)~The People's Poetry" and an associate professor of English at Indiana University. "It's a word that 一 and it depends on how a speaker uses it 一 can suggest being not worthy of attention or respect.’，Adams, who didn't take part in the poll and is not annoyed by "whatever," points out that its use is not always negative. “It can also be used in place of other neutral(中性的）phrases that have fallen out of favor, like ‘six of one, half dozen of the other，.” he said. However, he also noted that the negative meaning of the word might explain why “whatever，was judged more annoying than the ever-popular "you know”.
【小题1】Which tops second among the annoying expression according to the passage?'

【小题2】 What can we know about the word "whatever"?

A．It became popular because of Nirvana.

B．It can be commonly used at the beginning of an agreement.

C．Old people like it while young people don't.

D．Almost half of the Americans surveyed disliked it.

【小题3】In Adams' opinion, the reason why “whatever”，was judged more annoying may be that . _______

A．most of the people don't like it

B．it can be used in place of other neutral phrases

C．it carries certain negative meaning sometimes

D．the poor don't like it

【小题4】Which of the following statements is true?

A．Adams is not only a writer but also a professor.

B．“Whatever” is a signal of concern.

C．Adams is angry at the word “whatever”

D．"Whatever" will be replaced by "You know”.

Your smartphone can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little equipment of yours----- it might also spread disease.
“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.
Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said. What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.
So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.
【小题1】The underlined word “dark” in the first paragraph means _______

【小题2】Which of the following best describe the tone of the third paragraph?

【小题3】 By saying “Some things we think are personal are actually more public than we imagine,” Cain means that ________.

A．people love to share their phones more than they realize

B．our personal items could be as risky to our health as public items
