Monty owns a horse ranch （牧场） in San Sedro. Once when asked
about his ３6 , he told the story about a young
man, son of a horse trainer.
One day at high school the boy was asked to
write a paper about what he wanted to be and do when he ３7 .
That night he wrote a seven-page paper
describing his ３8 of someday owning a horse
ranch. He ３9 about his dream in great
detail and 40 drew a diagram (简图) of a 200-acre ranch, 41 the location （位置） of everything important there.
The next day he handed it in to his
teacher. Two days later he got his paper back. On the front page was a large
red F with a 42 that read, “See me after
class.”
The boy went to the teacher. The teacher
said, “This is an unrealistic dream 43 a
young boy like you. You come from a 44 family. Owning a ranch
requires a lot of money. There’s 45 way you could ever do it.”
Then he added, “ 46 you will rewrite this paper
with a more 47 goal, I will reconsider your 48 .”
The boy went home and thought about it long
and 49 . Finally, the boy turned in the
same paper, making no
50 at all. He
stated, “You can keep the F and I’ll keep my 51 .”
Monty then said, “I was that boy. And
the 52 part of the story is that
two summers ago that
53 teacher
brought 30 kids to camp out on my ranch for a week. When he was leaving, the
teacher said, ‘When I was your teacher, I was something of a dream stealer.

第三部分：阅读理解（共20小题；每题2分，满分40分）
请认真阅读下列短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项,并在答题卡上将该项涂黑。
A
Loose robes (长袍) with big sleeves. High collars and long skirts. It’s not a scene in a TV drama. Tying
up their hair and putting on the cotton shoes, about 60 young people gathered
in a Beijing
teahouse Monday to perform traditional dances, music and poetry readings.
The event was set up by Haanen.com, a
non-governmental organization founded in 2003. It has more than 24,000 members
worldwide. They all love traditional Chinese culture and believe that wearing
the Han costume （服装） is the
best way to show love for China. Active members are mostly in their 20s or 30s.
Chen Ye, a 19-year-old student, said it
made her feel bad that Koreans have hanbok and Japanese have kimono while Chinese
don’t have a typical traditional dress.
“Most people
may think the cheongsam(旗袍) could be a representative, but I don’t think so,” said Chen, from Capital University of Business and Economics.
Chen said Han costume is the one for China. It is
the traditional dress of Han nationality. It had been worn for thousands of
years before it died out at the end of the Ming Dynasty.
This is not the group’s first activity. In
the past two years, some of the members have dressed up in traditional clothes
and visited sights in the downtown areas of many Chinese cities. It helps raise
people’s awareness of traditional Chinese culture. Gu Xiaoming, history
professor with Fudan University, said the trend（倾向） is an attempt to hold on to traditional identities in a changing
world. “It’s a youth movement perhaps
springing up against the background of globalization.”
56. The young people gathered in a teahouse
in order to .
A. practise performing in preparation for a
TV play
B. found an organization to show love for
their homeland
C. give performances based on Chinese
traditional culture
D. join in an activity making traditional
Chinese clothing
57. It can be inferred from the passage
that the Han costume is most popular among
.
A. young people B.
history professors
C. TV play actors D.
visitors to teahouses
58. What does the underlined word “it” in
the last paragraph refer to?
A. The group’s first activity. B.
Dressing up in traditional costume.
C. Visiting sights in Chinese cities. D.
What the group has done so far.
59. What is the passage mainly about?
A. How important the Han costume has been
in the history of China.
B. Which costume should be regarded as the
traditional dress of China.
C. Why the Han costume reappears in some
young people’s life.
D. What a youth group has done to promote
traditonal Chinese culture.
B
Be sure you’re at the 2007 Super
Conference, the 88th national meeting of the Canadian Community Newspapers Association.
Ian Morrison, a futurist and author, will share his long-term forecasting on
changing business environments and throw light on the development of the
newspaper business model. Later in the day, you won’t want to miss David
Wilkins, the American ambassador to Canada, as he discusses affairs
affecting U.S.-Canada relations. Both presentations take place May 9―the
opening day of the conference.
On Thursday, May 10, meet Rob Curley,
vice-president of product development for the Washington Post, an online
innovator (革新者) whose
earlier work at the Naples, Florida Daily News, the small market Lawrence
Journal-World in Kansas, and with Morris Communications has made him an
innovative legend at age 35. His creativity has changed traditional thinking
about newspaper web sites, allowing for very local community web sites and
multimedia features. In 2004, Editor & Publisher named the
19,000-circulation(发行量) Lawrence Journal-World one of the ten newspapers in the U.S. that
“do it right.”
On Friday, May 11, speakers Juan, Media
Consulting Group and André, Gesca Ltd., will explore the trend（倾向） towards free and closely-related newspapers, which is not only a
European phenomenon, but has also appeared in North America. They will be
followed by Leon Levitt, vice-president of digital media for Cox Newspapers,
and others. They will address partnerships such as the one Yahoo! and several
large U.S.
newspaper companies have created, which are widely greeted as win-win for both
organizations.
For further information, and to download
the full program and registration form, visit

available in North America

By the end of this year, the contents of
all 1,800 courses taught at one of the world’s most famous universities will be available online to anyone in the
world, anywhere in the world. Learners won’t have to register (注册) for the classes, and everyone is accepted.
The cost? It’s all free of charge.
The Open Course Ware(OCW) movement, begun
at the Massachusetts Institute of Technology(MIT) in 2002 and now spread to
some 120 other universities worldwide, aims to spread knowledge to anyone who
has an Internet connection and a desire to learn.
OCW provides free access to course
materials such as video lectures, notes, homework and so on. By giving away
their content, the universities are not discouraging students from joining
them. Instead, the online materials appear to be only attracting more.
The MIT site, along with companion sites
that translate the materials into other languages, now average about 1.4
million visits per month from learners in every single country on the planet.
So-called “distance learning” over the Internet is not new. Students have been able to pay for
online courses at many institutions, either to receive credits（学分） or simply as a noncredit
adult-learning experience. Many universities also offer free materials
delivered through the Internet. But the total number and variety of the
educational materials being released (发布) provided by MIT is simply shocking. For example, each of the 29
courses that Tufts University in Medford,
Mass., has put online so far is
exactly the size of a textbook. The material provides much more than an outline
of a course. Visitors to Tufts’ OCW course on “Wildlife Medicine” call it the
most complete website on that topic in the world.
What OCW is not, its supporters agree, is a
substitute for attending a university. For one thing, OCW learners are not able
to receive instructions from a professor ― or to discuss the course with fellow
students. It is believed that a college education is really the total package
of students working with other students, forming networks, communicating with
teachers, and that whole environment of being associated with the school.
64. The purpose of the OCW movement is .
A. to help reduce the expenses of
university education
B. to win for MIT an advantage over other
universities
C. to provide educational materials through
the Internet
D. to make knowledge available to learners
on the Internet
65. According to the passage, what OCW
learners won’t have is .
A. free online course materials
B. credits after attending the courses
C. a non-credit adult-learning experience
D. normal communication with teachers and
classmates
66. The underlined sentence in the last
paragraph means .
A. OCW cannot take the place of normal
university education
B. OCW is believed to be a perfect match
for attending a university
C. OCW can offer students more materials
than attending a university
D. OCW can help learners complete university
education at a low cost
67. The passage is written mainly to .
A. excite young people’s learning desire B.
praise MIT for spreading knowledge
C. inform people about the OCW movement D.
tell people how to go to MIT for free
D
Besides news reports that tend to focus on
war or election, Americans generally don’t hear much about people in other
countries. One reason may be that very little foreign-language literature is
translated into English. In the United
States, just a few of the titles, mainly translations
of foreign novels, short stories, or poetry, make it into English. However, a
number of efforts have taken root to try to bring more global literature to US
audiences.
The online magazine of international
literature, Words Without Borders, was founded by Bard
College in Annandale-on-Hudson, N.Y.
The nonprofit site, now in its fifth year, offers modern writing from places
such as Argentina, China and Italy, often for the first time in
English. It gets about 200,000 page views per month and counts roughly 8,000
subscribers (订阅者) , more
than one-quarter of whom live in the US.
“There’s a
wave of interest right now,” says Jill Schoolman, publisher of Archipelago
Books, a small nonprofit press in Brooklyn, N.Y., opened in 2003 to publish
world literature in translation only. “People are hungry for ideas from other
countries.”
Rainmaker Translations ― a Las Vegas-based
nonprofit ― was formed two years ago to support the publication of more
top-quality global writing here in the US. They put out their first three
titles, translated from Arabic, Chinese, and Russian, in the spring of 2006 and
plan to aid up to four more in the coming year.
In March, the Center for the Art of
Translation, a nonprofit started in 1994 in San
Francisco, will publish Two Lines World Library,
focused on writing from some particular areas published over the last several
decades.
Dalkey Archive Press, a century-old
nonprofit publisher in Champaign,
Illinois, has upped the number of
translations on its publication list since 2003, from 25 percent to nearly 80
percent.
In recent years, more nonprofits have
applied to the National Endowment for the Arts for help to publish literary
translations. The agency is also trying to increase the availability of
translated prose (散文) and poetry in the US, such as publishing partnerships with foreign
governments.
68. The main purpose in founding the
magazine Words Without Borders is .
A. to compete for page views and
subscribers online
B. to get American literature better known
to the world
C. to help advance nonprofit world
literature translation
D. to introduce more world literature to
readers in the US
69. What do the publishers mentioned in the
passage have in common?
A. They mainly publish top-quality world
literature in translation.
B. They don’t aim at making money by
publishing global writing.
C. They provide their translation and
publication services online.
D. They have published a number of literary
works in translation.
70. Which of the following shows the proper
order of the founding of the presses (出版社)?
DAP = Dalkey Archive Press CAT
= Center for the Art of Translation
RT = Rainmaker Translations AB
= Archipelago Books
A. DAP→CAT→RT→AB B.
DAP→CAT→AB→RT
C. CAT→DAP→AB→RT D.
CAT→DAP→RT→AB
71. Which of the following can be the best
title for the passage?
A. World literature: Shared by the world B. World literature:
Loved by Americans
C. World literature: Found in translation D. World
literature: Developed in styles

Queensland has recently started to carry out a water recycling policy.
Queenslanders will be drinking recycled water as well as using it for other
purposes. They were quickly followed by South
Australia, where the government changed their former
anti-recycling policies.
So what is Victorian Government doing? It’s
bringing Victorians “good news” that they won’t have to drink recycled water.
Great... We actually have a government that is DUMBER than SA and QLD ones...
Good news indeed. Now every Melbournian knows ― we are smarter and better than
the Queensland
folks. Then why are we run by fools?
Bracks’ government has put the State’s
water protection on the constant force, by using dangerous and awful system for
its projects and failing to provide the necessary rules for the industrial
needs. After spoiling the water resources for years on end ― Bracksie blames
the households (i.e. YOU) for water wasteage. Ridiculous restrictions(限制) are made, supported by
Dob-your-neighbour phone line. Cars become dirty, grass becomes dead, naked
people bathe in the showers... Water resources keep on decreasing. So instead
of supporting recycling, Bracks owes it to people’s showing no attention. Most of Europe as well as parts of Asia
drink recycled water, despite not being in a serious draught(干旱) like Australia. Drinking
recycled water is SAFE, if the technologies used are proper ones.
Meanwhile, the real reason for the draughts
― environmental change is hardly being addressed by the State Government at
all. Yes, they have given us a target for CO2 20% decrease in 20 years’ time, but
we question: A, that is not enough; B, that is too far away;C, what is going to
be done to achieve those targets?
72． According to the author, it is for Victorian Government to refuse the water recycling policy.
A. necessary B.
great C.
unimportant D.
stupid
73. Victorian Government believes that .
A. the recycling policy of the other states
is effective
B. supporting water recycling is all
Victorians’ duty
C. giving a target to decrease CO2 also
means recycling
D. limiting the use of water resources is
very important
74. The author thinks that the decrease of
water is mainly caused by .
A. environmental pollution B.
industrial development
C. the government’s wrong policies D.
human beings’ wrong use
75. The passage mainly talks about .
A. a thirsty world B.
a wrong policy
C. a wise decision D.
a new research
