When I was a
child of seven years old，my
friends，on a holiday，filled my pocket with coppers．I went at once to a shop where they sold 36 for children． 37 the sound of a whistle
that I had seen by the way，in
the hands of another boy，I
handed over all my 38 for one．I
then came home, and went 39 all over the house, much pleased
with my whistle， 40
disturbing all the family．My brothers and sisters and cousins，when I told of 41
I had made, said I had given four times as much as the whistle was
worth．They put me 42 what good things I might have bought with
the rest of the money． 43
the matter gave me more disappointment
than the whistle gave me pleasure．
This，however, was afterwards of use to me，for the impression continued on my mind，
44 often, when I was tempted to buy
something I did not need，I
said to myself，“Don't give too much for the
whistle．”and I 45
my money． 46 I
grew up, came into the world，and
observed the actions of men, I thought I met with many，very many，who“gave too much for the whistle”．
If I knew a
miser who gave up every kind of comfortable living，all the 47 of doing good to others，all the esteem of his fellow citizens and the
joys of friendship， 48 gathering and keeping wealth―“Poor man,”said
I．“you pay too 49 for your whistle．”When I met a man of pleasure，who did not try to 50 his mind or his fortune but merely devoted
himself to having a good time，perhaps 51 his health,“Mistaken man，”said
I，“you are providing 52 for yourself, instead of pleasure; you
are paying too dear for your whistle．”If
I saw someone fond of 53 who had fine clothes，fine houses，fine
furniture，fine earrings，all
54 his fortune，and
for which he had run into debt,“Alas,” said I，“he
has paid dear，very dear，for his whistle．”In
short the miseries of mankind are largely due to their putting a 55 value on things to giving“too much for their whistles”．

第三部分 阅读理解(共两节，满分40分)
第一节选择题(共17小题；每小题2分，满分34分)
阅读下面的短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂黑。
A
John Steinbeck
once said，“All American believe they are born
fishermen．For a man to admit to a distaste
in fishing would be like speaking publicly against mother-love or hating
moonlight．”
I can't say I'm the biggest John
Steinbeck fan．Actually，the only thing I can ever remember read by him
was“The Pearl”when I was in middle school，but I couldn't agree more with the man when
it comes to fishing．When I am on a boat in the middle
of the Lay Lake，fishing off the shores of the
Florida Keys for tarpon or catching rainbow trout in the Shoshone River of
Wyoming．Fishing is my life．
According to the American Sports Fishing Association，the fishing industry brings in more than $116 billion per year from fishermen across the country．
However，fishing is much more than that．Fishing is a way of life for many people and a way to escape everyday stress．Being a fisherman makes me a member of a wonderful group of people extending to all walks of life．Even the former President Bush can be found fishing on his farm in Texas with his good friend Roland Martin when the jobs get too stressful．
I can remember fishing with my grandfather when I was 5 years old on his boat at Lake Mitchell．Although I didn't understand what I was doing, I did know that my grandfather was happy and that made me happy．Since then I've spent the past 16 years on the rivers and lakes of Alabama．
After days of practice，before and after work，I slowly developed an understanding of fishing．My boss，Ric Horst，took me back to the Shoshone, and I managed to bring in a 19-inch cutthroat trout．Fishing with Ric was a life-changing experience for me．He not only showed me how to fish correctly，but also told me how fishing could be a way to escape your problems．
Since then，prime-time season seems to take forever to arrive．
Now，with the ending of February and beginning of March in sight，the excitement of heading out to Lake Tus Caloosa or Lake Lurleen before classes and catching something has finally returned．
56．What John Steinbeck said in the first paragraph implies that ．
A．American are believed to be the offspring of fishermen
B．it is unthinkable for an American to admit his dislike of fishing
C．all American are expert at fishing
D．those who dislike fishing would not love their mother
57．The writer came to understand the real meaning of fishing ．
A．when he was reading“The Pearl”by John Steinbeck
B．when he went fishing with his grandfather at Lake Mitchell
C．after he had spent 16 years on the rivers and lakes of Alabama
D．after he went fishing with his boss，Ric Horst on the Shoshone
58．According to the author， ．
A．people can get to know VIPs when fishing
B．people can smooth away all the troubles by fishing
C．fishing is a way of communication
D．fishing is a way of life for most American people
59．What is the purpose of the writing?
A．To describe the writer's experience and understanding of fishing．
B．To explain the reason why so many Americans like fishing．
C．To make others understand the industry of fishing．
D．To express his opinions about fishing in different time of the year．
B
A strong wind can be a dangerous thing―sometimes it is powerful enough to knock you off your feet．But to plants，the wind is a source of new life，carrying them or their spores(孢子) thousands of miles．
A NASA satellite called QuikSCAT has discovered highways of wind over the Earth's oceans．Scientists believe these invisible roads may explain why many nonflowering plants，such as mosses(苔)and lichens(地衣)，grow where they do．
The satellite is able to send microwaves(微波)from space to the surface of the ocean．The pattern of signals that come back shows which way the winds are blowing．
Using this data，the scientists studied a group of islands in the southern hemisphere(半球)，near Antarctica．Winds tend to blow anticlockwise(逆时针)in this region，but there are lots of local differences．
When the researchers compared these local patterns to botanical(植物学)data，they found that the wind had an important effect on where species of mosses，lichens，and other nonflowering plants grow．
For example，Bouvet Island and Heard Island，share 30 per cent of their moss species，29 per cent of liverworts(叶苔)，and 32 per cent of lichens―even though they are 4，430 kilometers apart．In contrast，Gough Island and Bouvet Island，separated by just 1,860 kilometers of sea，share only 16 per cent of mosses and 17 per cent of liverworts．They have no lichens in common．
Ferns(蕨类植物)and flowering plants don't travel as well in the wind，so they don't show the same kinds of distribution(分布)patterns．
60．This story is about ．
A．the discovery of wind highways B．how wind travels
C．how wind affects different plants D．one function of the wind
61．The underlined word”data”in the fourth paragraph means“ ”．
A．signal B．pattern C．information D．research
62．Which of the following is WRONG?
A．Bouvet Island，Heard Island and Gough Island are all in the southern hemisphere．
B．Winds in the researched area blow anti-clockwise．
C．The scientists shouldn't base this research on how winds affect where ferns grow．
D．Without the discovery of QuikSCAT，the research wouldn't have made sense．
63．Which of the following diagrams shows the correct position of the islands?
 |
64．What is the writing style of this passage?
A．A news report． B．An argumentative writing．
C．An expository writing． D．A practical writing．
C
Personal Background
Steve Jobs
Apple Computer
3-year return：26%
AGE：42
CEO since：1997
Here's a guy with enough knowledge，ability and brainpower to effectively hold down two CEO jobs at once―and do a pretty amazing job at both．We've listed him for his post at Apple, but of course Steve Jobs also runs Pixar，the animation company．Coming in after a $ 1 billion loss in fiscal 1997，Jobs turned a $106 million profit―38 percent above Wall Street's consensus target．A lot of credit goes to a very simple idea: Make computers in different colors. Jobs was the only one who thought to make it happen．The colorful mid-priced iMac has also succeeded by playing down the compatibility(兼容性)problem．Apple positioned it as the machine for the Internet, where compatibility questions are no big deal．Behind the scenes，Jobs also streamlined the product line，reduced the head count，consolidated distribution，and slimmed inventory. Meanwhile，over at Pixar，A Bug's Life nabbed a total $159 million in domestic box office，the highest domestic animated take since Toy Story and third highest ever，after Toy Story and the leader，The Lion King．
Business philosophy：“The technology isn't the hard part．The hard part is，Who's going to buy it? How are they going to buy it? How do you tell them about it?”
How he got the job：The Apple board begged him to return．
Management Style：At Apple，Jobs is a micromanager―some say nanomanager who changes mood suddenly and unexpectedly．Virtually every decision goes by him. “At any time，10，000 employees are wondering，‘What would Steve say?’not‘What is the right thing to do?’”said a former Apple exec．At Pixar， realizing that he isn't a film visionary，he leaves the experts to their knitting．
Financial reward：His Apple rewards are minimal―a salary of one dollar a year so that his family is eligible for the health plan．But his 69 percent share of Pixar is worth about $ 1.3 billion.
65．According to the passage，the following adjectives can be used to describe Jobs EXCEPT ．
A．creative B．demanding C．easy-going D．distinguished
66．We can infer from the passage that ．
A．although Jobs does a good job at Apple，he isn't equal to handle his business at Pixar
B．iMac is Apple's hit product for its convenience and fair price
C．being a CEO at Apple，Jobs needs a considerable income to make sure that his family can get medical treatment
D．Jobs makes a big difference at Apple as a designer as well as a marketing planner
67．The underlined word“nabbed”in Para 2 probably means“ ”．
A．pulled up B．brought in C．went through D．handed over
68．The reason why Jobs doesn't involve himself much in animation is that ．
A．he considers himself neither professional nor qualified
B．he spends most of his time at Apple and spares little time at Pixar
C．he shows no talent for animation，nor is he into it
D．his 69 percent share of Pixar is worth about $1．3 billion，which enables him not to be concerned about the management
D
The“For Sale”signs are just starting to grow, but already experts worry that this spring home-buying season will be even tougher than the last．
Despite tentative signs of recovery in hard-hit areas like California and Florida，the broader housing market is far from reaching bottom, economists say．Across much of the nation, prices are likely to keep falling into 2010．
So this March-to-June season, when most homes are bought and sold，will be bad，perhaps the worst since the market began to spiral down in 2006．
Across the nation, 19 million houses and apartments―nearly one out of every seven―are vacant, the highest percentage since the 1960s．But only about six million of those homes are for sale or for rent．That means millions more could still flood onto the market，depressing prices further．
For would-be sellers, the bad news keeps coming．This week，one new report showed that one in nine mortgages(抵押)was illegal or in foreclosure(失去赎回权)，while another showed that January contract signings for sales of previously owned homes fell at their fastest pace in two years．
On Wednesday, the Obama administration announced details of a plan that will pay banks to lower monthly payments for troubled borrowers，hoping to prevent millions of foreclosures and keep more homes occupied．Despite that effort，most analysts expect the outlook to worsen．
But as the recession deepens，the downturn in housing, where the economic crisis began, is starting to play out in new，unexpected ways．Cities where home values held up last year are suffering now, while some suburban areas where prices fell arc slowly starting to improve．
“The further you get from the city，the more prices have declined，and that's where we see sales increasing．”said Glenn Kelman，chief executive of Redfin，a real estate brokerage firm．“Eighteen months ago, the city was the only place where people were still buying homes．”
In inland areas of California，for instance，sales are surging now that prices have fallen sharply．But most of the sellers are not individuals but rather banks that foreclosed on homeowners who could not or would not pay their mortgages．By contrast, in cities like New York and San Francisco, where prices have not fallen as much, the market is largely frozen．
69．What would be the best title for the passage?
A．A Gloomy Outlook for Home Sales' Big Season
B．New York Facing More Housing Problems
C．A Negative Effect of America's Financial Recession
D．Houses Becoming Cheaper in America
70．Why do experts think this spring season will be tougher than the last?
A．Because there are few signs of recovery in hard-hit areas．
B．Because citizens feel pessimistic about the Obama administration．
C．Because prices keep falling and more homes will flood onto the market．
D．Because many mortgages were illegal or in foreclosure．
71．According to the passage，which of the following is NOT true?
A．Not all vacant houses are for sale or for rent at the moment．
B．The Obama administration plans to repay loans for troubled borrowers．
C．This March-to-June season will be the worst season ever．
D．Home values in California used to fall，but now they start to rise．
72．The examples of California and New York show that ．
A．the recession is deepening
B．the economic downturn started in New York and then influenced California
C．banks tend to buy more houses instead of individuals
D．the housing market in cities is not as active as in suburban areas

Tears are nature's way of making us feel more comfortable．When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions，or when we are exhausted and“red-eyes”from over work and late hours, tears form in our eyes to clean and refresh them．
Tears are also a sign of strong emotion．We cry when we are sad and we cry when we are happy．And tears seem to be uniquely human．We know that animals also experience emotion fear，pleasure，loneliness，but they do not shed(流)tears．
Biologically speaking，tears are actually drops of saline fluid，which is a little bit salty，produced by a gland(腺)in the body．Because salt is an important component，tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea．
And it is clear that，in addition to the emotional benefits，the shedding of tears has a specific biological function as well．Through tears，we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body．Crying actually makes us feel better by correcting that imbalance and making us feel good again．And thus the emotional and the biological functions of tears merge(合并)into one and make us even more“human”than we would otherwise be．
73．What's the main idea of the first paragraph?(回答词数不超过8个单词)
74．The underlined part“tears seem to be uniquely human”in Paragraph 2 infers that“ ” ．(回答词数不超过6个单词)
75．In response to stress，how does crying make us feel better?(回答词数不超过10个单词)

Chinese researchers have developed a strategy that reduces the transmission of the parasitic illness schistosomiasis(血吸虫病)，known as“Snail Fever”，which affects an estimated 207 million people in rural parts of Asia and Africa．Experts say drugs alone do not work very well to control the disease．
The researchers are reporting in The New England Journal of Medicine that they have developed a strategy to reduce infections of the hard to control parasitic disease．
Experts say schistosomiasis can be a life-long illness that causes severe malnutrition(营养不良) and anemia(贫血症)．The infection occurs when human skin comes in contact with water contaminated(被污染的)with certain types of snails that carry eggs called schistosomcs．A vicious cycle begins when infected humans urinate(排尿) or defecate(排便)into the water and release the schistosomes，which mature into snails that lay eggs that infect others．
Standard treatment for the parasitic disease is a drug called praziquantel．
But international health professor Charles King of Case Western Reserve University in Cleveland，Ohio says the drug is not enough to eliminate the disease from communities because schistosomiasis is a cyclical disease．
“You treat the infection today，but if it comes back next year，that person will go on and get into that vicious cycle of illness，”he said．“So what they are reporting in this article is an attempt to go to a community and find out，’Exactly what does it take to really stop transmission?’And I think that is a really exciting move forward in this particular field．”
In their study，the researchers report the results of several
measures taken to reduce the schistosomiasis infection rate from 2005 through
The measures include improving sanitation by providing fresh tap water to residents，building lavatories，providing boats with tanks to store human waste and an education campaign．
In one village，the infection rate dropped from 11．5 percent to 7 percent and the infection rate fell from four percent to less than one percent in the second village．
Dr．King says slowing the cycle of infection, as the Chinese researchers showed, can have long-term benefits for impoverished(poor)villages where residents are stricken with schistosomiasis．
“We would expect to see a boost in health，what they call a‘virtuous cycle’，that all those improvements would feed into the community and help to improve their development．And that would actually facilitate changes that we need，”he said．
