单项选择题
1、根据以下资料，回答题：
        Drink from plastic bottles can raise the body's levels of a controversial "gender-bending" chemical by more than two thirds, according to tests．
        Experts have been concerned about the possible health effects of bisphenolA (BPA．--an everyday chemical used in many plastic food and drink containers and tins as well as clear baby bottles--which is officially classified as toxic in some countries．A study found that participants who drank for a week from polycarbonate (聚碳酸酯) bottles showed a 69 percent increase in their urine (尿液) of BPA．
        Researchers did not say how much liquid was drunk per day．Researchers from Harvard School ofPublic Health studied 77 students, who had first undergone a seven-day "washout" phase in which theydrank all cold beverages (饮料) from stainless steel bottles in order to minimise BPA exposure．
        They were then given two polycarbonate bottles and asked to drink all cold beverages from themduring the next week．Previous studies have suggested that high levels of BPA consumption are linked tobirth defects, growth problems and an increased risk of heart disease．In particular there are fears thatheating the bottles, as parents would do when warming their baby's milk, causes the chemical to leak inpotentially dangerous quantities into the liquid contained within．
        "If you heat those bottles, as is the case with baby bottles, we would expect the levels to beconsiderably higher．This would be of concern since infants may be particularly susceptible to BPA'shormone gland-disrupting (扰乱腺体极速分泌) potential．" said the senior author of the latest study, Karin B．Michels．
        Most adults carry BPA in their bodies but expert opinion on the risks is divided．The European Food Safety Authority believes that people naturally convert the chemical into less harmful substances in the body．
        Previous studies had found that BPA could leach (渗出 ) from polycarbonate bottles into theircontents, but this study is the first to show the size of the corresponding increase in urinary BPAconcentrations in humans．
        Harvard researcher Jenny Carwile said, "While previous studies have demonstrated that BPA is linkedto adverse health effects, this study fills in a missing piece of the puzzle--whether or not polycarbonateplastic bottles are an important contributor to the amount of BPA in the body．"

What do we know about bisphenol A (BPA．from the beginning of the passage?
A．It is certain substance taken in by human beings every day．
B．It is a component contained in a number of plastic products．
C．It is an element that plays a decisive role in people's gender．
D．It is a kind of chemical that is universally regarded poisonous．

Questions are based on the following passage.
To get a sense of how women have progressed in science, take a quick tour of the physics department at the University of California, Berkeley. This is a storied place, the 36 of some of the most important discoveries in modern science--starting with Ernest Lawrence's invention of the cyclotron (回旋加速器．in1931. A generation ago, female faces were 37 and, even today, visitors walking through the first floor of LeConte Hall will see a full corridor of exhibits 38 the many distinguished physicists who made history here, 39 all of them white males.
But climb up to the third floor and you'll see a 40 display. There, among the photos of current faculty members and students, are portraits of the 41 head of the department, Marjorie Shapiro, and four other women whose research 42 everything from the mechanics of the universe to the smallest particles of matter. A sixth woman was hired just two weeks ago. Although they're still only about 10 percent of the physics faculty, women are clearly a presence here. And the real 43 may be in the smaller photos to the right: graduate and undergraduate students, about 20 percent of them female. Every year Berkeley sends its fresh female physics PhDs to the country's top universities. That makes Shapiro optimistic, but also 44 "I believe things are getting better," she says, "but they're not getting better as 45 as I would like.
A．circumstance
B．confidence
C．covers
D．current
E．deals

3、Questionsare based on the following passage.
In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.
Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and fighting, have been shown to affect portion size and consumption.
A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them in other words, how much they remembered eating..
This disparity (差异) suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M. Brunstrom, a professor of experimental psychology at the Univerity of Bristol.
"Hunger isn't controlled solely by the physical characteristics of a recent meal. We have identified an
independent role for memory for that meal,'" Brunstrom says. "This shows that the relation_ship between hunger and food intake is more complex than we thought. ""
These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie(卡路里) milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙), depending on whether the shake's label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.
What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less. the new fmdings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.
The so-called mindful-eating strategies can fight distractious and help us control our appetite,
Brunstrom says.
What is said to be a factor affecting our appetite and food intake?
A．How we perceive the food we eat. 
B．what ingredients the food contains. 
C．When we eat our meals. 
D．How fast we eat our meals.

Exorbitant(过分的)Privilege
A．IN 2012 ICBC，a state．controlled Chinese company that is the world’s most valuable bank，bought four-fifths of the Argentine subsidiary of Standard Bank，a South African firm．The deal was hailed as a leap forward for “South-South” cooperation—direct economic ties between emerging markets(新兴市场)．But one group of fich-world middlemen got a slice of the action：lawyers．ICBC was represented by Linklaters，an English firm，and Standard Bank by Jones Day, an American one．The deal was made under English law, with any differences to be settled in A．l English arbitration center．
B．Though emerging markets now account for over half the world’s GDP at purchasing-power parity(购买力平价)，and trade between them is booming，just two developed countries retain a stranglehold on cross-border finance，investment，mergers and acquisitions．Just as America benefits from issuing the world’s reserve currency, America and its former colonial master, Britain, enjoy the exorbitant privilege of issuing the world’s “reserve law”．A global survey by Queen Mary University in London in 2010 of general counsels and legal-department heads found that 40% most frequently did business using English law and another 22% American．generally the law of New York state．No other country’s lawgot a significant share．
C．America and Britain reap large rewards from their legal dominance．of the world’s 100 highest-grossing law firms，9 1 have their headquarters in one of the two．America’s legal sector is bigger than the GDP of Peru；though much of that is because of Americans’ litigiousness．a good chunk comes from foreign work．The New York offices of American firms earn around$1．8 billion annually from international．dispute resolution．almost two．thirds of litigants in English commercial courts are foreign．At 1．5% ．the legal sector’s share of British GDP is nearly double that in other big European countries．
D．Other bits of both countries’ economies feel the ripples(余波)，t00．Foreigners visiting for legal hearings stay in hotels and eat in restaurants．Aspiring lawyers from around the world pay to attend their universities and spread goodwill when they go home．Dependence on American and British law firms makes it harder for deal makers to move from New York and London to Hong Kong or Frankfurt．Britain’s government describes lawyers as “central to the export of other professional services” such as accounting，asset management and banking．
E．The competition is often weak：much of China’s commercial law was written by Communist Party officials and is fiddled with errors：and though India adopted much of English common law, its courts are notoriously slow．But the incumbents’ biggest advantage is that they have common law systems with centuries of binding precedent．That means they offer as much certainty as any jurisdiction(司法权)can．In civil-law countries such as France，Portugal and Spain，and their ex-colonies，judges have wide latitude to interpret statutes，increasing the risk of nasty legal surprises．Civil systems place more restrictions on acceptable clauses，and often consider the interests of third parties，such as workers or consumers．
F．Many other countries would like to break this duopoly(双头垄断市场)．But even those with good laws on Paper would take decades to train enough lawyers and judges to make them stick．The immediate threat to American and British law comes from a trend that dispenses with courtsal together．Parties to a cross-border deal must decide not only which country’s law governs it but how disputes should be resolved．Firms are increasingly opting for private arbitration，which promises confidentiality,
speed and lower costs than going to court—and here London and New York are less dominant．
G．More recently，new entrants have made inroads．Among the most Successful is Singapore，whose dedicated arbitration venue(仲裁地点)，SIAC，opened in 199 1．Singapore’s government exempts arbitrators from income tax and expedites entry for participants in hearings．SIAC’s caseload has quadrupled in the past decade，with Indian firms particularly keen．Last year they were parties to a third of its 259 new cases．
H．With 260 new cases last year, Hong Kong matches SIAC for size．Arbitration is essential for cross-border deals involving China，since its iudges rarely enforce foreign court decisions but are bound to uphold arbitration awards by the New York Arbitration Convention，which it signed in 1987．In the past，Chinese firms reluctantly accepted distant arbitration venues．But they are increasingly insisting
on disputes being heard locally．Exorbitant no more?
I．English law remains prevalent in Asian arbitration，accounting for 32% of cases at SIAC．But a recent trend in South America shows how quickly this could change．Of the big emerging economies，the one mat has most effectively promoted its own law is Brazil．Its firms still use third．party law, usually New York’s．to raise money and make acquisitions abroad．But foreign firms active in Brazil often acquiesce to local law, relying on localarbitration as an alternative to courts that are politicized and glacially slow．
J．Brazil’s  govermment created a legal framework for arbitration in 1996，which became widely used after being approved by the supreme court in 200 1．Nothing prevents firms from using foreign arbitration—but losers may delay the application of foreign rulings for years(though not for ever)by filing objections in Brazilian courts．In contrast，domestic arbitration awards in local-law cases are deemed
equivA．ent to legal rulings，and implemented on the spot．“There’s nothing to fear about having an arbitration in Brazil，”says Stepheno’ Sullivan，a former solicitor in England who works for Mattos Filho，a Brazilian firm．
K．At first sight，the lawyers of Wall Street and the City of London have the most to lose from the growing popularity of arbitration．Their govermments are not helping．In Britain authorities often fail to provide timely visas for parties，experts or witnesses．As for America，businesses often complain about the burden of pre．trial discovery, and the threat of unsophisticated juries or elected judges awarding exorbitant damages．In a recent survey, Hogan Lovells，a law firm whose main offices are in London and Washington，DC，asked general counsels around the world which jurisdiction they found most challenging．China finished second--after America．
L．In the long run，developing countries may be bigger losers．Local arbitration may facilitate deals and bolster short．term growth．But if it reduces the pressure from multinationals and local finns for simpler laws，berer courts and less political corruption，it may delay attempts to establish legal systems that work not just for businesses but for everyone else too．

6、        Questions are based on the following passage.
        The federal automobile efficiency standards announced this week are an important step on America's path to a lower-carbon and more-secure energy future. They are expected to yield multiple benefits: reduced dependence on foreign oil, fewer greenhouse gas emissions, consumer savings at the pump and a more competitive auto industry. They may also serve as proof that well-tailored government regulation can achieve positive results and that consensus among old enemies--in this case environmentalists and the car companies--is possible even at a time of partisan (党派的) disagreement.
        The standards build on a 2009 agreement that established a unified set of rules governing fuel economy and carbon dioxide pollution from automobiles and light tracks. Those rules covered model years 2012-16 ; the new rules cover 2017 to 2025. Taken together, the two sets of rules would increase fuel efficiency from today's average of about 29 miles per gallon to 54.5 miles per gallon when they are fully effective in 2025. This is expected to result in a cut of 40 percent to 50 percent in fuel consumption and roughly equivalent cuts in greenhouse gas emissions.
        The White House says the rules would reduce oil consumption by two million barrels a day by 2025;the nation now consumes 19 million barrels a day and imports just less than haft that amount. And while fuel-efficient cars will cost more initially, lower fuel use is expected to save consumers up to $8,000 over the life of their vehicles.
        The battle for greater fuel economy goes back years and involved many players: California, which in2002 passed its own law regulating greenhouse gas emissions from vehicles sold there; environmenttalists,who pressured the Environmental Protection Agency to impose similar rules nationwide; the Supreme Court, which in 2007 authorized the agency to move forward; and Congress, which ordered the Department of Transportation to update fuel economy standards that had been largely untouched since 1975. President Obama's contribution was to bring about a consensus among the agencies, the states, the automakers and the interest groups on federal and state standards that reduced fuel use and gave industry the regulatory certainty it needed to move forward.
        It is a model of public-private cooperation. Even so, the Romney campaign has called the rules "extreme" and House Republicans have threatened to roll them back. That would be a grave harm to consumers, the auto companies, the economy and the planet.
The federal automobile efficiency standards announced this week______.
A．help to eliminate partisan disagreement between the two parties
B．enable Americans to be independent from foreign oil
C．help to promote consumption of gas and automobiles
D．can result in a lower-carbon and more-secure energy future
