A
Steve Nash enjoys team success far
more than personal success, and always wants to share the glory and the joy
with teammates.
He is a self-effacing (不爱出风头的) Canadian, who
grew up in hockey country. Today Steve Nash has to stand alone even if he
doesn’t enjoy it. The Phoenix
Sun’s point guard has to take ownership of a set of skills that sets him apart
from every bigger, faster basketball player. He is considered the best basketball
player in the game.
31-year old Nash was named the
Most Valuable Player (MVP) of the NBA on May 8, 2005. “It’s unbelievable,” he
said．“It’s been a long road for me and I really enjoy playing as
a team, just trying to be a good teammate. That is the only way for me to highlight
what I do as a basketball player.”
It is the first time a Canadian
has won any individual NBA honor. Of the 50 winners of the MVP award, only six
have been guards: Steve Nash, Magic Johnson, Oscar Robertson, Michael Jordan,
Allen Iverson, and Bob Cousy. “I’m happy for him getting the MVP, which makes
us feel like we all got the MVP,” said Phoenix
forward Shawn Marion.
He may be the only one who truly
believes he can reach this level. “I always try to set goals for myself and
have my own time frame to accomplish them and I never give up on anything,” he
said．It is not as if Nash arrived at this point without
countless hours of hard work.
His interests go far beyond sports
and the NBA．His social conscience is such that he wore a T-shirt
bearing an anti-war slogan at the NBA all-star weekend festivities in Philadelphia in 2002.
“A lot of great moments are when
you win games with your teammates. There’s nothing like sharing something with
someone else,” he said．“There is a pinnacle (顶点) of a player’s career individually. In many
ways, the pinnacle of a player’s career really is defined by team wins.”
56．What does Steve Nash
mean by saying the last two sentences?
A．A player’s success is
decided by his / her individual efforts.
B．A player won’t
succeed without a team’s support.
C．A player will succeed
sooner or later.
D．A team always decides
a player’s success.
57．Steve Nash feels
happiest _______.
A．when he is named the
Most Valuable Player of the NBA
B．when he is 30 years
old
C．when he plays at the
NBA all-star weekend festivities
D．when his team wins a
game
58．Which of the
following statements is TRUE according to the passage?
A．Nash is an American
basketball player.
B．Nash is better at
basketball than Magic Johnson.
C．Nash is the first
Canadian winner of the MVP award.
D．Michael Jordan is the
best of the six guards.
59．Which of the
following is the main message that the passage wants to express?
A．Nash prefers team
honor to personal honor.
B．Hard work will lead to
the honor of the MVP of the NBA.
C．A Canadian can be an
MVP of the NBA.
D．Setting goals is of
importance to success.

Like most people, I’ve long
understood that I will be judged by my occupation, that my profession is a
standard people use to see how smart or talented I am. Recently, however, I was
disappointed to see that it also decides how I’m treated as a person.
Last year I left a professional
position as a small-town reporter and took a job waiting tables. As someone
paid to serve food to people. I had customers say and do things to me I suspect
they’d never say or do to their most casual acquaintances（泛泛之交. One night a man
talking on his cell phone waved me away, then beckoned (示意) me back with his
finger minute later, complaining he was ready to order and asking where I’d
been.
I had waited tables during summers
in college and was treated like a peon (勤杂工) plenty of people. But at 19 years old, I
believed I deserved inferior（较差的)treatment from professional adults. Besides, people
responded to me differently after I told them I was in college. Customers would
joke that one day I’d be sitting at their table, waiting to be served.
Once I graduated, I took a job at a
community newspaper. From my first day, I heard a respectful tone from everyone
who called me. I assumed this was the way the professional world worked .
I soon found out differently. I sat
several feet away from an advertising sales representative with a similar name.
Our calls would often get mixed up and someone asking for Kristen would be
transferred to Christie. The mistake was immediately evident. Perhaps it was
because money was involved, but people used a tone with Kristen that they never
used with me.
My job title made people treat me
politely. So it was a shock to return to the restaurant industry.
It’s no secret that there’s a lot to
put up with when waiting tables, and fortunately, much of it can be easily
forgotten when you pocket the tips. The service industry, by definition, exists
to satisfy to others’ needs. Still, it seemed that many of my customers didn’t get the difference between server and
servant.
I’m now applying to graduated
school, which means someday I’ll return to a profession where people need to be
nice to me in order to get what they want, I think I’ll take them to dinner
first, and see how they treat someone whose only job is to serve them.
64. The author was
disappointed to find that ____
___.
A. one’s position is used as a
standard to measure one’s intelligence
B. talented people like her should
fail to get a respectable job
C. one’s occupation affects the way
one is treated as a person
D. professionals tend to look down
upon manual waitresses
65. What does the
author intend to say by the example in the second paragraph?
A. Some customers simply show no
respect to those who serve them.
B. People absorbed in a phone
conversation tend to be absent-minded.
C. Waitresses are often treated by
customers as casual acquaintances.
D. Some customers like to complain
because of the waitress’ poor service.
66. How did the
author feel when waiting tables at the age of 19?
A. She felt it unfair to be treated
as a mere servant by professional.
B. She felt badly hurt when her
customers regarded her as a peon.
C. She was embarrassed each time her
customers joked with her.
D. She found it natural for
professionals to treat her as inferior.
67. The underlined sentence “many of
my customers didn’t get the difference between server and servant” in Paragraph
7 means “
”.

are sure to be looked down upon.

industry shouldn’t be treated as servants.

up with rough treatment to earn a living.

The North and South poles are remote and freezing places
that receive lots of animal visitors but few human tourists.
But even if you never plan to visit the polar bears in the
north or penguins in the south, now is a perfect time to start thinking about
them. That’s because 2007 marks the beginning of the International Polar Year
(IPY), a two-year-old activity of science projects that aim to show how
important the poles are to the health of our planet. During the IPY, which will
last until March 2009, thousands of researchers from more than 60 countries
will conduct more than 200 projects and expeditions to both the top and bottom
of the world.
In recent years, the polar regions have begun to change
severely as a result of global warming. Temperatures there are rising faster
than anywhere else on Earth. As a result, the ice and snow in these regions are
melting at record-setting rates. One result is that sea levels are rising
around the world, putting animals and people at risk.
Only by studying the poles, say IPY researchers, can we
find ways to protect them and ourselves.
Both the Arctic and the
Antarctic are cold and remote, but the two regions have important differences.
For one thing, the Arctic is an ice-covered
ocean surrounded by land. The Antarctic, on the other hand, is a continent of
ice-covered land surrounded by water.
Most polar studies have focused on the Arctic,
and that is where scientists have observed the most remarkable changes in the
ice. During a typical year, Arctic ice expands in the winter and shrinks in the
summer. But recently, the amount of ice covering the ocean has been steadily
dropping in both seasons.
68．Which of the
following might be the best tile of the passage?
A．Earth’s Poles
Interest Scientists
B．The Animals of
Earth’s Poles
C．Earth’s Poles in
Danger
D．The Discoveries of
Earth’s Poles
69．The goal of the
International Polar Year is __________.
A．to make it clear that
the poles have much to do with a healthy earth
B．to provide practical
theory to further develop this distant area
C．to cal on as many
scientists as possible to do research on the poles
D．to discover more
mysteries unknown to man
70．What is the main
factor that has caused the changes of the poles?
A．The increasing number
of animals.
B．The development of
the poles.
C．The melting of the
poles.
D．The rising
temperature.
71．What unusual
phenomenon worries the scientists?
A．In summer the ice of
the Arctic loses faster.
B．The ice covering the Arctic decreases even in winter.
C．The ice of the Arctic
increases less than in the past.
D．The changes in the Arctic are more serious.

Feeling tired? Under too much
stress? Well, you may want to try Yoga(瑜珈). It’s what more and more people have been
turning to to release the trouble of modern life. Practically unheard of in the
West until 50 years ago, Yoga has become one of the most popular health trends
around the world, including China.
If you search for Yoga on line in Chinese, lots of pages are there to see, most
of which are main pages of Yoga clubs. In order to keep fit and lose weight,
many girls spend more than 1000 yuan taking part in Yoga classes every month.
However, are you really ready for
it? There are several things you need to know before you really take it.
First, do not force your body too
much. Yoga has many difficult poses. They are beautiful and worth boasting if
you could finish them. But if you force yourself to do as exactly as an
experienced Yoga teacher does, you may hurt your body, instead of strengthening
it. Do you remember you original purpose for playing Yoga? It is self
-building, not competing.
Second, do some research about the
Yoga class that you are to register. Yoga is new in China and there are not so many
certificated well-trained Yoga teachers. Some not well organized clubs just
find someone learn a little Yoga and certificate them. But be aware, a non-eligible
teacher might wrongly guide you and you could not benefit from the classes much
except that they force you to exercise your body a bit. Considering about the
large amount of money you invest in it, it’s worth and reasonable to make sure
the teachers in the club are qualified before you join.
Third, it
would be better to learn something about nutrition when you practice Yoga. In
the very beginning, Yoga was part of the Vedas, bible of the traditional Indian
philosophy. So it could be regarded as a kind of lifestyle. When you have
decided to care for your body, why not feed it properly? In fact, good clubs
have their own nutritionists.
Anyhow,
make sure you are ready before you act. The fashion may change quickly. But
what benefits is still good for us.
72．The author’s main
purpose in writing the passage is to .
A．tell people how to
relax themselves
B．let people know more
about Yoga
C．give people some
advice on taking part in Yoga classes
D．tell peoples Yoga has
gained its popularity in China
73．The underlined word “eligible”
in the fourth paragraph most probably means .
A．experienced B．qualified C．honored D．hi-technical
74．Which of the
following is NOT the author’s advice?
A．Join one of the
noblest Yoga clubs.
B．Don’t easily follow
the fashion about Yoga.
C．Know some knowledge
about nutrition.
D．Find out a real teacher.
75．From the advice
offered by the author, we can conclude that .
A．Yoga has nothing to
do with culture
B．Yoga is somehow easy
to exercise
C．many people learn
Yoga in order to complete
D．not all the Yoga
clubs have standard teachers
