【单选题】Flying across the country the other day, I sat next to a retiredAir Force colonel, and we had a pleasant conversation about love of flying, travel and grandchildren and for him, of retirement itself. "Yeah," he said, "there’s only one thing that would make me give this up. "
"What’s that "
"If Hillary or Jan Fonda runs for president, I’m going to work full time to beat her. "
I told him I knew Hillary. She doesn’t even need a last name now.And she’s no Jane Fond
A、
"Well," I concluded before we began talking about planes and kids again, "I think you are going to get your chance. I think she’s going to run. "
I once wrote, with total sincerity, that I thought Hillary RodhamClinton had the political instincts of a stone. I also wrote that I thought she had marginalized her husband’s chances of being an important president.
He blew that by naming his wife to head the task force to work out a national plan, and she decided to work in secret with battalions of "experts" who came up with a plan four times as long as theEuropean constitution.
Then, after taking her lumps for that, she decided to run, as aDemocrat, for the US Senate from New York, a state she had always thought was a nice place to visit.
She is now far and away theDemocratic front-runner for president in 2008. Her national numbers are getting better, inch by inch, day by day. Now, a slight majority—52 percent in a couple of polls—say they are likely or very likely to vote for Hillary for president. True, 47 percent, including my friend the colonel, still say "Never. "But her national approval-disapproval rate is now about 55 to 39, compared with 46 to 48 for PresidentBush.
The odds are still against her. So are most of the odds-makers, beginning with Joe Klein of Time Magazine, chronicler of theClintons in fact and fiction. He believes a Hillary candidacy will polarize the country the way the reign of theClintons polarized us in the 1990s.
The word "polarize" in the last paragraph probably means ______.
A、personalize
B．popularize
C．unite into one group
D．divide into opposing sides

【单选题】If pollution continues to increase at the present rate, formation of aerosols in the atmosphere will cause the onset of an ice age in about fifty years’ time. This conclusion, reached byDr. S. I. Rasool andDr. S.H. Schneider of the United States Goddard Space FlightCentre, answers the apparently conflicting questions of whether an increase in the carbon dioxide content of the atmosphere will cause theEarth to warm up or increasing the aerosol content will cause it to cool down. TheAmericans have shown conclusively that the aerosol question is dominant.
Two specters haunting conservationists have been the prospect that environmental pollution might lead to the planet’s becoming unbearably hot or colD、One of these ghosts has now been laid, because it seems that even an increase in the amount of carbon dioxide in the atmosphere to eight times its present value will produce an increase in temperature of only 2 ℃, which would take place over several thousand years.But the other problem now looms larger than ever.
Aerosols are collections of small liquid or solid particles dispersed in air or some other medium. The particles are all so tiny that each is composed of only a few hundred atoms.Because of this they can float in the air for a very long time. Perhaps the most commonly experienced aerosol is industrial smog of the kind that plagued London in the 1950s and is an even greater problem in LosAngeles today. These collections of aerosols reflect the Sun’s heat and thereby cause theEarth to cool.
Dr. Rasool andDr. Schneider have calculated the exact effect of a dust aerosol layer just above theEarth’s surface in the temperature of the planet.As the layer builds up, the present delicate balance between the amount of heat absorbed from the Sun and the amount radiated from theEarth is disturbeD、The aerosol layer not only reflects much of the Sun’s light but also transmits the infrared radiation from below. So, while the heat input to the surface drops, the loss of heat remains high until the planet cools to a new balanced state. Within fifty years, if no steps are taken to stop the spread of aerosols in the atmosphere, a cooling of theEarth by as much as 3.5 ℃ seems inevitable. If that lasts for only a few years it would start another ice age, and because the growing ice caps at each pole would themselves reflect much of the Sun’s radiation it would probably continue to develop even if the aerosol layer were destroyeD、
The only bright spot in this gloomy forecast lies in the hope expressed byDr. Rasool andDr. Schneider that nuclear power may replace fossil fuels in time to prevent the aerosol content of the atmosphere from becoming critical.
Aerosols can float in the air for a very long time in that they ______.
A、can result in industrial smog
B．are liquid particles
C．are dispersed in air
D．are composed of tiny articles

【单选题】Concern with money, and then more money, in order to buy the conveniences and luxuries of modern life, has brought great changes to the lives of most Frenchmen. More people are working than ever before in France. In the cities the traditional leisurely midday meal is disappearing. Offices, shops and factories are discovering the greater efficiency of a short lunch hour in company lunchrooms. In almost all lines of work emphasis now falls on ever-increasing output. Thus the" typical" Frenchman produces more, earns more, and buys more consumer goods than his counterpart of only a generation ago. He gains in creature comforts and ease of life. What he loses to some extent is his sense of personal uniqueness, or individuality.
Some say that France has beenAmericanizeD、This is because the United States is a world symbol of the technological society and its consumer products. The so-calledAmericanization of France has its critics. They fear that" assembly line life" will lead to the disappearance of the pleasures of the more graceful and leisurely (but less productive) old French style. What will happen, they ask, to taste, elegance, and the cultivation of the good things in life--to joy in the smell of a freshly picked apple, a stroll by the river, or just happy hours of conversation in a local cafe ,
Since the late 1950’s life in France has indeed taken on qualities of rush, tension, and the pursuit of material gain. Some of the strongest critics of the strongest critics of the new way of life are the young, especially university students. They are concerned with the future, and they fear that France is threatened by the triumph of this competitive, goods-oriented culture. Occasionally, they have reacted against the trend with considerable violence.
In spite of the critics, however, countless Frenchmen are committed to keeping France in the forefront of the modern economic worlD、They find that the present life brings more rewards, conveniences, and pleasures than that of the past. They believe that a modern, industrial France is preferable to the olD、
Which of the following best states the main idea of the passageA．Change in the French way of life.
B．Criticism of the new life style.
C．TheAmericanization of France.
D．Features of the new way of lif

【单选题】Suppose you are driving on a highway with three lanes going in your direction and you come upon a toll plaza with six toll booths. Three toll booths are straight ahead in the three lanes of traffic, and the three other booths are off to the right. Which lane should you choose There are usually enough people searching for the shortest line so as to make all the lines about the same length.
The term profit in economics has a very precise meaning.Economists, however, often loosely refer to "good deals" or profitable ventures with no risk as profit opportunities. Using the term loosely, a profit opportunity exists at the toll booths if one line is shorter than the others. The general view of economics is that profit opportunities are rare.At any one time there are many people searching for such opportunities, and as a consequence few exist.
At major banks in big cities, you can buy foreign currencies. The prices of these currencies are determined in world money markets. With dollars we can buy marks; with these marks we can buy francs; and with these francs we can buy back dollars.Can we make money on this transaction If this is possible, we say that there are profit opportunities in the market. There are in fact almost never any profit opportunities of this kind in foreign currency markets. There are always individuals looking for such opportunities, and if any opportunity does arise it is quickly eliminate
D、
If, for example, the mark-franc price is too low with respect to the other prices, there is an immediate rash to buy marks and sell francs, not by ordinary citizens at bank windows, but by a few large currency traders in Tokyo, London, or Zurich who watch prices every minute. Such a rush drives up the mark-franc price to the no-profit-opportunity point. Markets like this, where any profit opportunities are eliminated almost instantaneously are said to be efficient markets.
The common language way of expressing the efficient markets hypothesis is "there’s no such thing as a free lunch". How should one react when a stock broker calls up with a hot tip on the stock market With skepticism. There are thousands of individuals each day looking for hot tips in the market, and if a particular tip about a stock is valid there will be an immediate rush to buy the stock, which will quickly drive its price up.By the time the tip gets to your broker and then to you, the profit opportunity that arose from the tip (assuming that there was one) is likely to have been eliminate
D、 Similar arguments can be made for bond markets and commodity markets. They are many "expert" in these markets, who take quick advantage of any news that affects prices.
This economist’s view that there are very limited profit opportunities around can, of course, be carried too far. There are clearly times when profit opportunities exist. Someone has to be first to get the news, and some people have quicker insights than others. Nevertheless, news does get disseminated quickly, and there are thousands of people with quick insights. The general view that profit opportunities are rare is close to the mark.
The economists think the profit opportunities are rare because
A、the market is not efficient. B、too many people go for it.
C、the prices are always fluctuating.
D、few people have the clear insights.
