閱讀理解
     Celebrity (名人)  has  become  one  of the  most  important representatives of popular culture. Fans
used to be crazy about a specific film, but now the public tends to base its consumption (消費(fèi)) on the
interest of celebrity attached to any given product.Besides, fashion magazines have almost abandoned
the practice of putting models on the cover because they don't sell nearly as well as famous faces. As a
result , celebrities have realized their unbelievably
powerful market potential, moving from advertising for others' products to developing their own.
     Celebrity clothing lines aren't a completely new phenomenon,but in the past they were typically aimed
at the ordinary consumers ,and limited to a few TV actresses. Today they're started by first-class stars
whose products enjoy equal fame with some world top brands.The most successful start-ups have been
those by celebrities with specific personal style. As celebrities become more and more experienced at the market, they expand their production scale rapidly,covering almost all the products of daily life.
     However,for every success story , there's a related warning tale of a celebrity who overvalued his
consumer appeal. No matter how famous the product's origin is ,if it fails to impress consumers with its
own qualities it begins to resemble an exercise in self-promotional marketing. And once the initial (最初的 ) attention dies down, consumer interest might fade , loyalty (忠誠(chéng))  returning to tried-and-true labels.
     Today, celebrities face ever more severe embarrassment. The pop-cultural circle might be bigger than
ever, but its rate of turnover has speeded up as well. Each misstep threatens to reduce a celebrity's shelf
life
, and the same newspaper or magazine that once brought him fame has no problem picking him to
pieces when the opportunity  appears. Still, the ego's  (自我的 ) potential for expansion is limitless.
Having already achieved great wealth and public recognition,many celebrities see fashion as the next
frontier to be conquered. As the saying goes ; success and failure always go hand in hand. Their success
as designers might last only a short time, but fashion-like celebrity-has always been temporary.
1. Fashion magazines today_________. 
A. seldom put models on the cover
B. no longer put models on the cover
C. need not worry about celebrities' market potential
D. judge the market potential of every celebrity correctly
2. A change in the consumer market can be found today that________.
A. price rather than brand name is more concerned
B. producers prefer models to celebrities for advertisements
C. producers prefer TV actresses to film stars for advertisements
D. quality rather than the outside of products is more concerned
3. The underlined sentence in Paragraph 4 indicates that any wrong step will possibly________ .    
A. decrease the popularity of a celebrity and the sales of his products
B. damage the image of a celebrity in the eyes of the general public
C. cut short the artistic career of a celebrity in show business
D. influence the price of a celebrity's products
4. The passage is mainly about___________.            
A. celebrity and personal style
B. celebrity and market potential
C. celebrity and fashion design
D. celebrity and clothing industry

     Mayor Boris Johnson Monday outlined plans to make London "the cleanest, greenest
city on Earth" by the 2012 Olympics and called for commitments from other world cities
at a climate change conference. Leaders of the world's 40 largest cities are meeting in
Seoul this week for a summit on combating global warming -- the third to be held since
2005.
     "What we should do in Seoul is agree that we will stop the endless addiction of
mankind to the internal combustion engine (內(nèi)燃機(jī))," said Johnson. He said at a press
conference the world's cities consume 75 percent of the world's energy and produce
80 percent of the emissions which cause climate change. "The problem of our planet is
an urban problem," Johnson said.
     He said the British capital wants to use the Olympics "to drive the greening and the
improvement of our city" and noted that London is committed to reduce carbon dioxide
emissions by 60 percent by 2025.
     Johnson said the key measure was being taken to solve problems relating to housing
and commercial buildings, which accounted for 70 percent of carbon dioxide emissions
in London. This involved retrofitting (翻新) -- installing lagging -- in large numbers
of public buildings.
     Johnson proclaimed himself a "passionate cyclist" and said he would push ahead
with cycle superhighways around London.
     London's air quality problem, he said, was caused by vehicle emissions from 8,300
worn and used diesel (柴油) buses, which could be replaced by low-carbon vehicles.
In addition, there were also 32,000 taxis running on diesel fuel, which could be replaced
by electric vehicles.
     Johnson said there would be a few programs in the next few years to produce a
"cleaner, greener" bus for the city. "The age of the diesel bus has got to be over in
London."
1. Which would be the best title for the passage?______
A. The third summit on global warming
B. London plans to make the cleanest and greenest city on Earth by 2012
C. Some measures to deal with pollution
D. The problem of our planet appeared
2. Which of the following statements is NOT TRUE according to this passage.'?______
A. London's air quality will be improved in the near future.
B. The used buses running on diesel will be replaced by electric vehicles.
C. London promises to reduce carbon dioxide emissions by 60 percent by 2025.
D. Something has been done to solve the problem of carbon dioxide emissions.
3. What does the underlined word mean in the first paragraph?______
A. Resisting.
B. Objecting.
C. Agreeing
D. Solving
4. The topic of the meeting in Seoul might be______
A. climate change
B. global warming
C. London Olympics in 2012
D. green environment
5. If the passage was continually written, the following might be _____.
A. measures to end the age of the diesel bus
B. measures to reduce carbon dioxide emissions in London
C. measures to solve housing and commercial items
D. measures to replace the old and used vehicles

     Driving a car is not just handling controls and judging speed and distance. It requires you to predict
what other road users will do and get ready to react to something unexpected. When alcohol is
consumed, it enters your bloodstream and acts as a depressant(抑制藥), damaging eyesight, judgement
and coordination(協(xié)調(diào)), slowing down reaction time and greatly increasing the risk of accidents. Even
below the drink driving limit, driving will be affected.
      Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain.
Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with
fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up
with any measures like taking a shower or having a cup of tea or coffee.
     The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
     ● 50 milligrams of alcohol per 100ml of blood; or
     ● 22 micrograms of alcohol per 100ml of breath; or
     ● 67 milligrams of alcohol per 100ml of urine(尿液).
     Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of
drink driving will be tested.
     Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a
maximum of HK $25,000 and be sentenced to up to 3 years in prison and punished for 10
drivingoffence points; or temporarily banned from driving.
     The same punishment applies to failing to provide specimens(樣本) for breath, blood or urine tests
without good excuse.
      Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of
yourself and other road users, never drive after consuming alcohol.
1. The first paragraph is mainly about ________.
A. the introduction of driving skills
B. the damage of drinking to your body
C. the effect of drinking on driving
D. the process of alcohol being absorbed
2. The underlined word "it" in the second paragraph refers to "________".
A. alcohol   
B. absorption
C. blood  
D. process
3. Which of the following is TRUE according to the passage?
A. Drinking below the drink driving limit has no effect on driving.
B. Alcohol is taken in more quickly when drunk with fruit juice.
C. Having a cup of tea helps to get rid of alcohol from the body.
D. 50 milligrams of alcohol per 100ml of breath is below the drink driving limit.
4. A driver suspected of drink driving________.
A. should provide specimens for testing
B. will be forbidden to drive for 3 years
C. will be punished for 10 drivingoffence points

     Information has always been at the center of human communication.Yon may ask why.Well,
communication between people contains giving and receiving information. The way we give and receive
information today has experienced a revolution in the development of the mass media in the 20th century.
     The first truly mass communication medium was the newspaper. For the first time in history people
could read about events in their country and from around the world every day. However there were two
problems with newspapers of that time. Firstly, newspapers were available only in large cities, for getting
newspapers to the countryside was a difficult and timeconsuming (耗時(shí)的) task. Secondly, newspapers
weren't always reliable, as there was a limited range of opinions.
     Nowadays, we can choose from a wide variety of sources to get information. Television and the
Internet have given us the chance to be informed about everything the minute it happens. Large numbers of radio and TV stations, satellite channels and millions of websites help people keep up with the latest news.People live in history and are part of it.
     The media have come a long way in the last century and there is no doubt that we now live in the
information age. Whatever type of media we choose, it all comes down to the need for information.This
will always be a basic need as long as communication is part of human nature.

     What can help you make a fortune in the future? Graduating from a top university might not be
enough. A new study from the University of Essex in Britain has shown that the more friends you
have in school, the more money you'll earn later.
     The idea that popularity could have a serious impact on one's earning potential shouldn't come as
too much of a surprise. The researchers noted that if you want to get ahead in life, social skills and
networking are easily as powerful as talent and hard work.
     "If a person has lots of friends, it means that he or she has the ability to get along with others in all
kinds of different situations, " said Xu Yanchun, 17, from Nantou High School in Shenzhen, who totally
agreed with the recent finding. "Also, friends always help each other. They not only create wider social
circles for you but lift your mood when you occasionally feel depressed, " said Xu. She believed that all
this helps you "earn a higher salary".
     Maybe that's why some people think the younger generations are in the age of friendaholism(交友狂癥). A woman even complained that the networking website Facebook's 5,000friend limit was too low
for her large reserve of social contacts.
     But what does a friend mean? Should friends be regarded as a form of currency?
     "Call me uncool, but I think of a friend as an actual person with whom I have an actual history and
whom I enjoy actually seeing. It seems, however, that this is no longer the definition(定義)of 'friend', "
said Meghan Daum, who works with The Los Angeles Times in the US.
     Daum despised(鄙視)the idea that quantity trumps(勝過(guò))quality in the age of friendaholism. She
thought the idea of friendship, at least among the growing population of Internet social networkers, was
to get as many of notreallyfriends as possible. For example, a friend might be someone you might know
personally but who could just as easily be the friend of a friend of some other Facebook friends you
don't actually know.
1. What's the main idea of the passage?
A. Making friends is important.
B. Making friends makes you earn more money.
C. Friends give you success.
D. Social skills are important.
2. Which of the following sentences is TRUE?
A. It is surprising that making more money is popular with people.
B. If you want to win in life, social skills are as important as talent and hard work.
C. The young now have friendaholism.
D. Friends do not create your wider social circles but lift your mood when you occasionally
     feel depressed.
3. What's the opinion of Xu Yanchun about making friends?
A. Making friends may help you a lot in your life.
B. Making friends can get a lot of money.
C. Making friends can make you work hard.
D. Making friends can improve your ability to work.
4. What's the author's attitude?
A. Objective.  
B. Subjective.
C. Neutral.  
D. Optimistic.
