C
An oasis (绿洲) is an island of life in an ocean of temperature extremes．Any oasis always contains one or more springs Oases make it possible to survive through the desert．In large deserts such as the Sahara．towns are located around sources of water such as oases and rivers．
What causes an oasis? An oasis is actually a spot in the desert where the altitude is low enough that the water table is fight below the surface，resulting in the presence of springs．Even in a desert, it rains occasionally，and this produces a water table just above the bedrock，usually several hundred feet below the surface．Sand is very porous (可渗透的)，so most water runs right
through it and down to the bedrock．
Deserts consist of many millions of tons of sand．There is only one natural force capable of moving it in noticeable amounts：the wind．Although，in an average dust storm，ten cubic feet of air only holds about an ounce of sand，a cubic mile of air can move about 4,600 tons of it，leading to erosion (侵蚀)．A severe storm is capable of moving as much as 100 million tons of sand and dust．
In certain areas where large quantities of sand are moved by storms，erosion digs all the way down to the water table，putting it just beneath the surface Seeds planted in the ground there are capable of extending roots into the moist land，producing an oasis．
Sometimes．the oasis produced by the wind can be very large when vast tracts of desert are wiped clean by storms．The great Kharga oasis in the Sahara，for example，is over 100 miles long and 12 to 50 miles in width. The oasis was produced when erosion caused the edges of the hollow places to sink down to the water table.
63．What does “it” in Paragraph 4 refer to_______．
A．erosion        B．water table          C．sand                      D．storm
64．How many conditions of the oasis formation are mentioned in the passage without considering
The wind and seeds?
A．3                B．4                        C．5                           D．6
65．We can infer from the passage ________．
A．there is at least one spring on an oasis
B．the bedrock is usually just right below the surface
C．the great Kharga oasis is the biggest oasis in the world
D．the great Kharga oasis is at a low altitude
66．In the last paragraph，the author mentions the great Kharga oasis as an example to_______．
A．introduce the great oasis to the readers
B．tell how the oasis was produced by rain
C．show the oasis produced by the wind can be very large

第二部分阅读理解（共20小题，每小题2分，满分40分）
A
Watching television more than two hours a day early in life can lead to attention problems later in adolescence, according to a study released on Tuesday.
The roughly 40 percent increase in attention problems among heavy TV viewers was observed in both boys and girls. The link was established by a long-term study of the habits and behaviors of more than 1,000 children born in Dunedin, New Zealand, between April 1972 and March 1973.
The children aged 5 to 11 watched an average of 2.05 hours of weekday television. From age 13 to 15, time spent in front of the tube rose to an average of 3.1 hours a day.
"Those who watched more than two hours, and particularly those who watched more than three hours, of television per day during childhood had above-average symptoms of attention problems in adolescence," Carl Landhuis of the University of Otago in Dunedin wrote in his report, published in the journal Pediatrics.
Young children who watched a lot of television were more likely to continue the habit as they got older, but even if they did not the damage was done, the report said.
"This suggests that the effects of childhood viewing on attention may be long lasting," Landhuis wrote.
Landhuis offered several possible explanations for the association.
One was that the rapid scene changes common to many TV programs may over stimulate（刺激）the developing brain of a young child, and could make reality seem boring by comparison. "Hence, children who watch a lot of television may become less tolerant of slower-paced and more mundane tasks, such as school work," he wrote.
It was also possible that TV viewing may supplant other activities that promote concentration, such as reading, games, sports and play, he said.
Previous studies have linked the sedentary固定不动的）habit of TV watching among children to obesity and diabetes, and another study in the same journal cited the poor nutritional content of the overwhelming majority of food products advertised on the top-rated US. children"s television shows.
Up to 98 percent of the TV ads promoting food products that were directed at children aged 2 through 11 "were high in either fat, sugar, or sodium," wrote Lisa Powell of the University of Illinois in Chicago.

A. watching TV can cause all kinds of diseases for children
B. TV sets have played an important part in our daily lives
C. Watching TV over 2 hours a day early in life can cause attention problems later in adolescence
D. watching TV has side effects on children’s future
57. People used to think that _________.
A. watching TV more than 2 hours every day did good to children’s health
B. the sedentary habit of TV watching among children could easily lead to obesity and diabetes
C. the children wasn’t patient with their homework because of watching TV too much
D. it was very important for children to watching TV early in life
58. The underlined word “Hence” means _________.
A. In that case B. And yet C. On the contrary D. For this reason
59. In Landhuis’ opinion, _________.
A. attention problems caused by watching TV during childhood may be hard to get rid of

C. the key of settling attention problems is not watching TV too much

       ……
This election had many firsts and many stories that will be told for generations. But one that"s on my mind tonight’s about a woman who cast her ballot in Atlanta. She is a lot like the millions of others who stood in line to make their voice heard in this election, except for one thing: Ann Nixon Cooper is 106 years old.
She was born just a generation past slavery; a time when there were no cars on the road or planes in the sky; when someone like her couldn"t vote for two reasons, because she was a woman and because of the color of her skin.
And tonight, I think about all that she"s seen throughout her century in America: the heartache and the hope; the struggle and the progress; the times we were told that we can"t, and the people who pressed on with that American creed: Yes we can.
At a time when women"s voices were silenced and their hopes dismissed, she lived to see them stand up and speak out and reach for the ballot. Yes we can.
When there was despair in the Dust Bowl and depression across the land, she saw a nation conquer fear itself with a New Deal, new jobs, a new sense of common purpose. Yes we can.
When the bombs fell on our harbor and tyranny threatened the world, she was there to witness a generation rise to greatness and a democracy was saved. Yes we can.
She was there for the buses in Montgomery, the hoses in Birmingham, a bridge in Selma, and a preacher from Atlanta who told a people that "we shall overcome." Yes we can.
A man touched down on the moon, a wall came down in Berlin, a world was connected by our own science and imagination. And this year, in this election, she touched her finger to a screen, and cast her vote, because after 106 years in America, through the best of times and the darkest of hours, she knows how America can change. Yes we can.
America, we have come so far. We have seen so much. But there’s so much more to do. So tonight, let us ask ourselves, if our children should live to see the next century; if my daughters should be so lucky to live as long as Ann Nixon Cooper, what change will they see? What progress will we have made?
(From Obama’s victory speech, 2008 )

Some of the United States’ biggest banks have closed their doors to students at community colleges, for-profit universities and other less competitive schools, even as they continue to extend government-backed loans to students at eh nation’s top universities.
Citibank has been among the most active in rebuilding the list of colleges it serves. JPMorgan Chase, PNC and SunTrust say have not dropped whole loan plans, but are cutting colleges. Some less-selective four-year colleges, like Eastern Oregon University and William Jessup University, say they have been dropped by some lenders.
The practice suggests that if the credit crisis and poor conditions in the student loan business continue, some of the nation’s neediest students will be hurt most. The difficulty of borrowing money may keep them from attending school or force them to take a semester（学期） off. For those who have got student loans, they will end up with less attractive terms and may run a greater risk of dropping out if they have to change lenders in the middle of their college year.
Tuition and loan amounts can be quite small at community colleges. But these institutions, which are a stepping stone to other educational programs or to better jobs, often draw students from the lower ranks of the economic classes. According to the most recent data, about a third of US graduates took out loans, a majority of them guaranteed by the government.
“If put too many obstacles in their way to get a loan, they ’ll take a third job or use a credit card,” said Jacqueline K. Bradley, assistant director for financial aid at Mendocino College. “That almost guarantees that they won’t be as successful in their college career.”
Some loan companies have stopped the students loan business entirely, viewing it as unprofitable in the current environment. Students attending first-class, expensive, public and private four-year universities can expect to remain plentiful. The banks generally say these loans are bigger, more profitable, and less risky, perhaps in part because the banks expect graduates from these universities to earn more.
So far, financial aid administrators say they have been able to find some lenders that students can switch to, but this is costly to students--- in money and time.
59. Who will be the most upset at the news?
A. A poor students at a top university.          B. A poor students at a community university.
C. A bank clerk dealing with student loan business.
D. A teacher from a for-profitable university.
60. With too many obstacles in their way to get a loan, students will probably __________.
A. switch to top universities                       B. cancel their credit cards
C. fail in their exams                                 D. win a scholarship
61. When they say something is “government-backed”, you mean it is ___________.
A. guaranteed by the government                B. dropped by the government
C. against government                               D. for government
62. What is the best title for the passage?
A. The students loan business in America.    B. Banks and universities in America.
C. Student loans start to drop colleges.        D. Credit crisis starts to affect loans.
