Homebuyers
nationwide are watching housing prices go up, up, and up. “How high can they
go?” is the question on everyone’s lips. “It’s 36 ,” said Tim, who is
looking for a house near the beach. “In 1993, I 37 my first place, a two-bedroom
condominium(公寓)in Venice, for $70,000. My friends thought 38 that I was overpaying. Five years
later, I had to move. I sold it for $230,000, which was a nice 39 . Last year, while visiting friends
here, I saw in the local paper that the exact same condominium was 40 for $510,000!”
It is a
seller’s market. Homebuyers feel like they have to 41 at least 10 percent more than the
asking 42 . Donna, a new
owner of a one-bedroom condominium in Venice Beach,
said, “That’s what I did. I told the owner that no matter 43 anyone offers you, I’ll give you
$20,000 more, under the table, so you don’t have to pay your realtor(房地产经纪人)any of it. I
was 44 looking.”
Tim says he

yourself for 48 a great opportunity.”
Everyone says
the bubble(泡沫)has to 49 sometime, but everyone hopes it will
burst the day 50 they sell
their house. Even government officials have no idea what the 51 will bring. “What goes up must come
down,” said the state director of housing. “ 52 , as we all know, housing prices
always 53 a little higher than they go
down. So you can’t 54 over
the long run. Twenty years down the road, your house is always worth more than
you 55 it.”

第三部分：阅读理解（共20小题；每小题2分，满分40分）
第一节：选择题（共17小题：每小题2分，满分34分））
阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
It was Thanksgiving morning and in
the crowded kitchen of my small home I was busy preparing the traditional
Thanksgiving turkey when the doorbell rang. I opened the front door and saw two
small children in rags huddling(拥挤)together
inside the storm door on the top step.
“Any old papers, lady?” asked one
of them.
I was busy. I wanted to say “no”
until I looked down at their feet. They were wearing thin?little sandals(便鞋), wet with heavy snow.
“Come in and I’ll make you a cup
of hot cocoa.”
They walked over and sat down at
the table. Their wet sandals left marks upon the floor. I served them cocoa and
bread with jam to fight against the cold outside. Then I went back to the
kitchen and started again on my household budget.
The silence in the front room
struck me. I looked in. The girl held the empty cup in her hands, looking at
it. The boy asked in a flat voice, “Lady, are you rich?”
I looked at my shabby slipcovers(沙发套). The girl put her cup back in its saucer(茶碟)carefully and said, “Your cups match your
saucers.” Her voice was hungry with a need that no amount of food could supply.
They left after that, holding their bundles of papers against the wind. They
hadn’t said “Thank you.” They didn’t need to. They had reminded me that I had
so much for which to be grateful. Plain blue china cups and saucers were only
worth five pence. But they matched.
I tasted the potatoes and stirred
the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with
a good steady job ? these matched, too.
I moved the chairs back from the
fire and cleaned the living room. The muddy prints of small sandals were still
wet upon my floor. Let them be for a while, I thought, just in case I should
begin to forget how rich I am.
56. Two children came to the
writer’s front door because .
A.
it was Thanksgiving Day. B.
they were beggars
C.
they wanted old papers D.
they wanted a cup of cocoa
57. Why did the writer let the
children in?
A.
She showed great pity on them. B.
She had old papers to sell.
C.
She wanted to invite them to dinner. D.
She wanted them to see how rich she was.
58. From the passage, we can infer
that whether you are rich depends on .
A.
how much money you have had B.
how you feel about your life
C.
how you have helped others D.
what job your husband is doing
59. The writer left the muddy
prints of small sandals on the floor for a while to .
A.
show her husband that someone had come B.
remind her that she had helped two children
C. remind her that she was very once rich D.
remind her how life should be
B
Small discoveries in Indonesia are causing a stir in the
science world. Researchers have unearthed
(挖掘) tiny bones
that they believe belong to an entirely new human species. If that’s true, it
will change how we think about our ancestors.
Clues that the little people may have lived long ago
were first revealed last year in the scientific journal Nature. Scientists said that they had found the bones of a
three-foot-tall female on the island
of Flores, in Indonesia. When
they looked more closely, they saw that the nearly complete skeleton (骨骼) belonged to a full-grown adult. Researchers named her Hobbit,
after the tiny heroes of the Lord of the
Rings books.
Now the team is saying it has unearthed even more
pieces of the puzzle, including a jawbone and parts of arms, legs and hands
from several individuals, as well as stone tools. They reported their find in Nature this month. “The new evidence
makes it very clear that these people are a new species, distinct from modern
humans,” Peter Brown, a scientist on the team, said. They named these ancient
humans Homo floresiensis.
Brown says that these little people lived as recently as 12,000
years ago. If Homo floresiensis was a
different species from modern humans, that would make our family tree bigger
than we knew. It means, says Brown, that “until recently, a relative shared the
planet with us.”
Many scientists think a new species is unlikely. Some
argue that the bones must have belonged to modern humans whose small size was
the result of a genetic problem.
Daniel E. Lieberman, a scientist at Harvard University,
thinks that the debate over the discovery is healthy. He believes that the
questions and arguments raised by critics will help us learn more about these
unusual skeletons. “Disagreement is an important part of the scientific
process,” Lieberman said. “As far as I’m concerned, the story’s only just begun.”
60. Researchers name the skeleton Hobbit because _____.
A. it is a
figure described in the Lord of the Rings B. it resembles the tiny heroes in
a set of books
C. it proves
to be a full-grown adult D.
it belongs to an ancient human species
61. Small discoveries in Indonesia are important because they
_____.
A. are
revealed in the scientific journal Nature B.
are made by Peter Brown, a famous scientist
C. are about ancestors
of modern humans D.
might provide new evidence for human study
62. According to Daniel E. Lieberman, _____.
A. Homo floresiensis doesn’t exist
B.
disagreement leads to further research
C. the investigation hasn’t
begun yet
D.
our family tree is bigger than we knew
63. Which of the following might be the best title of the passage?
A. Comparison
between Different Peoples B.
Arguments over Human Origin
C. Discovery
of a Possible New Human Species D. History of Indonesian People
C
64. What does Passage ① tell us about the boy?
A. He was
injured in the head when he was 14.
B. He has waited for the payout for a long
time.
C. He has
lived in the same place since the accident.
D. He was run
over by a taxi when riding on the pavement.
65. What can we learn about Lee and Collier counties from Passage②?
A. They both became
safe places. B. They won the same
place in a race.
C. They had the same number of accidents.
D. They joined hands in reducing accidents.

Every year, the American Library
Association honors artists and writers of books for children. One of these
honors is the Newbery Award. It is named after a book seller in England in the
18th century, John Newbery.
The Newbery Medal winner for 2006
is Lynne Rae Perkins for writing Criss
Cross. Her book is about four teenagers in a small town. They are trying to
find the meaning of life and love. They are fourteen years old. Criss Cross is written in several
different ways. Sometimes it is like a song. Sometimes it is like a poem. Lynne
Rae Perkins is a writer and artist. Criss
Cross is her sixth book.
Another
award, the Caldecott, honors the best American picture book of the year. It is
named after an artist from England,
Randolph Caldecott. The Caldecott Medal winner this year is Chris Raschka for
the book The Hello, Goodbye Window,
written by Norton Juster.
In
the book, a little girl tells about visiting the home of her grandparents. The
committee that chose Chris Raschka for the award praised how he captures the
natural way children draw. It says the pictures express the emotional warmth of
connections between older family members and children, Chris Raschka also won
the award in 1994. In addition to the winners, four Caldecott Honor Books and
four Newbery Honor Books were named last month.
Another honor from the American
Library Association is the Margaret L. Batchelder Award. It goes to the company
that publishes the best translation of a children’s book into English. The
winner for 2006 is Arthur A. Levine Books for the book An Innocent Soldier written by Josef Holub. Michael Hoffman translated
it from German.
Awards
are chosen by committees of people who work with children’s books. But in some
schools, children vote unofficially for their own Newbery and Caldecott
winners. This year, schoolchildren could watch the award ceremony live on the
Internet. A teacher in Wisconsin
says her students cheered as each winner was announced.

第二节 简答题（共3小题， 满分6分）
阅读下面短文，根据第73至第75小题的具体要求，简要回答问题。
Ballroom dancing
Ballroom dancing(交际舞)in
the UK used to be seen as something rather unpopular that old people might do. For the past five years
though, the popularity of ballroom dancing has soared(高涨)thanks to a
reality TV show. Every Saturday night millions of people watch the show which airs from September right up to
Christmas. In the show a number of professional ballroom dancers each partner a celebrity(名流). Every week they have to learn a different ballroom
dance and perform it live on TV
on the Saturday night.
Four judges,
all of whom have a background in professional dance, give the celebrities scores and comments about their
dances. It is then up to the
public to call in and vote for their favorite couple. The two least favorite
then have to dance again and the judges decide who stays in the competition and
who leaves. The celebrities get to wear colorful dresses to dance in, and it
looks like a lot of fun.
The TV program also shows what good exercise
it can be to ballroom dance and what hard work is involved(涉及)in learning the dances and performing them
properly. Dance schools around the country have seen an increase in the number of people wanting to learn how to dance.
And it’s not only older people who are interested. Lots of children and young
people in their 20s are eager to
learn.
The show demonstrates how glamorous(富有魅力的)ballroom dancing is. The format(形式)for the show has been copied in lots of
countries around the world. In America,
the show is called Dancing with the Stars and at the moment they are doing very
well in the show. In the British show there are famous TV stars and former sportsmen taking part. So you
can forget your usual exercise?why not learn a foxtrot(狐步舞), a tango or the less
energetic waltz. It’s the fashionable thing to do!
73. Find
in the passage a word closest in meaning to the underlined word “demonstrates”.
74. Why are so many people interested in ballroom dancing in the UK? (回答词数不超过8个)
75. How
does the TV show make so many people enjoy the TV program?（回答词数不超过8个）

注意：每空不超过3个单词。
The US
Department of Labor statistics show that there is an oversupply of college
trained workers and that this oversupply is increasing. Already there have been
more than enough teachers, engineers, physicists, aerospace experts and other
specialists. Yet colleges and graduate schools continue every year to turn out
highly-trained people to compete for jobs that aren’t there. The result is that
graduates cannot enter the professions for which they were trained and must
take temporary jobs which don’t require a college degree.
On the other
hand, there is a great need for skilled workers of all sorts. These people have
more work than they can deal with, and their annual incomes are often higher than
those of college graduates. The old gap that white-collar workers make a better
living than blue-collar workers no longer holds true. The law of supply and
demand now favors the skilled workmen.
The reason for this situation is the traditional myth
that college degree is a passport to a prosperous future. A large part of
American society matches success in life equally with a college degree. Parents
begin indoctrinating(灌输) their children with this myth before they are out of grade school.
High school teachers play their part by acting as if high school education were
a preparation for college rather than for life. Under this pressure the kids
fall in line. Whether they want to go to college or not doesn’t matter.
Everybody should go to college, so of course they must go. And every year
college enrollments go up and up, more and more graduates are overeducated for
the kind of jobs available to them.
The development of our society is made by all kinds
of workers. Only when the need of them is balanced can our nation process
healthily. So parents and teachers are wished to pay more attention to the
children’s choices.
