Winter begins in the north on December 22nd.People and animals have been doing what they always do to prepare for the colder months, Sqzeirrels, for example, have been busy gathering nuts from trees. 1.They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut(黑胡桃）trees2. The black walnut tree is also a central part of some hardwood forests.

Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student nowat the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels.Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places.3. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring.Red squirrels, however, store large groups of nuts above ground.

4.But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century. The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade（涌入）Indiana.5.

A. Gray squirrels are native to Indiana.

B. But they seldom remember where they buried every nut.

C. Red squirrels bury nuts in a different way.

D. The black walnut is the nut of choice for both kinds of squirrels.

E. Jake Goheen calls them a sign of an environmental problem more than a cause.

F. Scientists are worried that they will drive away the gray squirrels.

G. Well, scientists have been busy gathering information about what the squirrels

do with the food they collect.

We are not who we think we are.

The American self-image is spread with the golden glow of opportunity．We think of the United States as a land of unlimited possibility，not so much a classless society but as a place where class is mutable—a place where brains，energy and ambition are what counts，not the circumstances of one's birth.

The Economic Mobility Project， an ambitious research led by Pew Charitable Trusts， looked at the economic fortunes of a large group of families over time， comparing the income of parents in the late 1960s with the income of their children in the late 1990s and early 2000s．Here is the finding: "The 'rags to riches' story is much more common in Hollywood than on Main Street． Only 6 percent of children born to parents with family income at the very bottom move to the top.

That is right， just 6 percent of children born to parents who ranked in the bottom of the study sample， in terms of income， were able to bootstrap their way into the top． Meanwhile， an incredible 42 percent of children born into that lowest are still stuck at the bottom，having been unable to climb a single rung of the income ladder.

It is noted that even in Britain---a nation we think of as burdened with a hidebound class system-children who are born poor have a better chance of moving up． When the studies were released，most reporters focused on the finding that African-Americans born to middle-class or upper middle-class families are earning slightly less，in inflation-adjusted dollars，than did their parents.

One of the studies indicates，in fact，that most of the financial gains white families have made in the past three decades can be attributed to the entry of white women into the labor force．This is much less true for African-Americans.

The picture that emerges from all the quintiles，correlations and percentages is of a nation in which，overall，"the current generation of adults is better off than the previous one"，as one of the studies notes.

The median income of the families in the sample group was $55，600 in the late 1960s; their children's median family income was measured at $71，900．However，this rising tide has not lifted all boats equally．The rich have seen far greater income gains than have the poor.

Even more troubling is that our nation of America as the land of opportunity gets little support from the data．Americans move fairly easily up and down the middle rungs of the ladder，but there is "stickiness at the ends" —four out of ten children who are born poor will remain poor，and four out of ten who are born rich will stay rich.

1.What did the Economic Mobility Project find in its research?

A． Children from low-income families are unable to bootstrap their way to the top.

B． Hollywood actors and actresses are upwardly mobile from rags to riches.

C． The rags to riches story is more fiction than reality.

D． The rags to riches story is only true for a small minority of whites.

2.It can be inferred from the undertone of the writer that America，as a classless society，should ________.

A． perfect its self-image as a land of opportunity

B． have a higher level of upward mobility than Britain

C． enable African-Americans to have exclusive access to well-paid employment

D． encourage the current generation to work as hard as the previous generation

3.Which of the following statements is TRUE according to the passage?

A． The US is a land where brains，energy and ambition are what counts.

B． Inequality persists between whites and blacks in financial gains.

C． Middle-class families earn slightly less with inflation considered.

D． Children in lowest-income families manage to climb a single rung of the ladder.

4.What might be the best title for this passage?

A． Social Upward Mobility.

B． Incredible Income Gains.

C． Inequality in Wealth.

D． America Not Land of Opportunity.

Tiny transmitters(发射机) fixed on the backs of the blue-green bees have allowed scientists to follow the insects as they fly for miles in search of rare flowers．

Working in Panama，scientists caught 17 bees of the common species and fixed a 300 milligram radio light onto the back of each．The signals they sent out were used to follow their movements in and around the forest where they lived．

Professor Martin，from Princeton University，US，and the Max Planck Institute for Ornithology in Germany，said，“By following the radio signals，we discovered that male bees spent most of their time in small centre areas，but could take off and visit areas farther away．One male even crossed over the shipping lanes in the Panama Canal，flying at least 5km，and returned a few days later．”

Researchers have struggled to follow the movements of bees before，following bees marked with paint or using radar which doesn’t work well in forests．

“Carrying the transmitter could reduce the distance that the bees travel，but even if the flight distances we record are the shortest distances that these bees can fly，they are impressive，long-distance movements，” said Dr．Roland Kays，from New York State Museum，a co-author of the research published today in the on-line journal．“This result helps to explain how these bees’ pollination(授粉) can be so rare．” Pollination by bees and other insects is the key to the diversity and continued growth of flowers and trees in some forests．

The new study is the first to use radio transmitters to follow bees in a forest．Similar research may now be carried in temperate forests，where bees also play a vital role．

1.The main purpose of the passage is to___

A． call on people to protect the bees for the environment

B． explain why the bees fly far away in search of flowers

C． introduce a modern way to follow the bees to readers

D． encourage the public to support the scientists' research

2.What was the problem when researchers tried to follow the bees in the past?

A． It was quite difficult to mark the bees

B． The radar itself didn't work very well

C． The bees weren't easy to be recognized

D． Environmental limits were hard to solve

3.What Dr．Roland Kays said implied that____

A． he didn't expect bees could fly so long a distance

B． The transmitter didn't have any effects on bees at all

C． He wanted to know how far bees could travel badly

D． The record was in fact as exact as he had thought

4.Researchers follow the movements of bees mainly to___

A． learn how far they can fly at most

B． discover how they affect the plants

C． correct some wrong ideas about bees

D． get to know where they enjoy living
