The wheel was one of man’s first inventions and yet it has also proved one of the most useful. So wide and varied are the uses of the wheels, in machines and vehicles of all kinds, that it is difficult to imagine what the world would be like without them. It is surprising to hear it said, therefore, that the wheel’s importance will perhaps be greatly reduced by the end of the century by an invention so new as to be still unnamed.
The invention is a machine the floats above any surface on a cushion of air. The cushion is formed when air is blown into this saucer, the machine rises to a height that may vary from a few inches to a few feet.
Industry is already using one form of the inversion to deal with heavy loads. It can lift them. with ease and since there are no wheels, and therefore no friction , they can be put into motion with the touch of a finger.
The new invention, however , is having a great effect on transport, Not only does it make expensive road systems unnecessary, but it enables vehicles to travel well over land or water. This unique to reach most destinations has given rise to the prediction that wheeled vehicles may be uncommon at the end the century as aeroplanes were at the beginning.
1. The first paragraph tells us that______.
A. the wheel was man’s earliest invention.
B. the wheel’s usefulness has yet to be proved.
C. wide wheels have a variety of important uses.
D. a new invention may make wheels less important.
2. The phrase “with the touch of a finger” in the third paragraph means______.
A. without difficulty                   B. by electricity .
C. without friction                    D. by hand.
3. The passage tells us that the new invention __________.
A. is more important for industry than for transport.
B. will one day be used instead of aeroplanes.
C. makes it possible to travel without using roads.
D. will replace wheeled vehicles using roads.
4. According to the passage, the new invention _______.
A. will soon get a name                        B. can go almost anywhere
C. is lighter than air                             D. was uncommon a century ago

I got lots of interesting experiences in a free school. At first I couldn’t believe it. There were no    41   in rows or loud-sounding bells, nor did anyone have to go to   42  . Although we lived “in”,    43  made us go to bed at a certain time; there was no “ lights out”.
The    44 thing was that practically all the students went to class, and very few people stayed up late at night. Only the new people stayed up or    45 class. The new ones always went wild    46  , but his wildness never lasted long. The freedom took some getting used to.

The subjects were the same as those in the ___50_____ school, but what a difference in the method!

I didn’t take    55__ . But I could do the basic things with numbers. That’s   56  .
  57_    I think I am a     58   person for having gone to the school. I can read and write as well as anyone else of my age, and I think better. That’s probably a real big      ___59    between the free school and the regular school--- the amount of    60  .

For more than two decades, Oprah Winfrey has been the change-your-life champion who ruled over daytime television much like Johnny Caron once ruled late night.
However, now she’s ready to say goodbye, Wimfrey told viewers Friday that The Oprah Winfrey Show would close in September 2011 after 25 years on the air.
“I love this show. This show has been my life. And I love it enough to know when it’s time to say goodbye,” Winfrey said, holding back tears.
Winfrey’s show “is one of daytime television’s very foundations,” said Larry Gerbrandt an analyst for the firm Media Valuation Partners in Los Angeles. “Stations build their schedules around her. They gave it the best time period and used it to promote other shows.”
Winfrey offered no specific plans for the future, except to say that she intended to produce the best possible shows during the final two years.
“I just wanted to say whether you’ve been here with me from the beginning or you joined me last week, I want you all to know that my relationship with you is one that I hold very dear,” she said. “Your trust in me and the sharing of your precious time every day with me have brought me the greatest joy I have ever known.”
The Oprah Winfrey Show’s open atmosphere and frank conversation determined the talk show style and made Winfrey one of the most influential women in the US as well as the wealthiest black woman in the world.
“She has had great effects on today’s society. She’s just part of every one’s life,” said Yasmeen Elhaj, a 19-year-old student from Chicago.

Positive thinkers admit when they feel frustrated(受挫折的) or depressed, they don't ignore it.But they don't blame themselves either.Instead, they try to understand the negative thoughts and feelings and counter(反擊) them with more positive ones.
So how do you stay positive, maintain motivated and sustain(保持) healthy behaviors? Here are some tips:
Look for a good role model.There is always someone who seems to be doing just what you want to be doing.Maybe they've scheduled exercise into their workday and switched from coffee to green tea.Learn from a successful friend, family member or colleague.Ask them how they keep healthy and follow in their footsteps.

Get support.Tell your friends and family about your healthy habits.It helps to have an encouraging network.
Reward yourself.Treat yourself to something for your healthy efforts.Take a nice bath, get a massage, and enjoy a new DVD or CD.
Have a plan.Making a plan to exercise or eat healthy lunches with a friend can mean the difference of sticking with your goals or falling off track.If you've planned for an activity, you'll likely stick with it.You may even find that writing down your goals and steps to achieve them can help you stay on track.Take it day by day or week by week.The process of writing down your personal action plan is a good way to keep you honest and watch your progress or failures.

Ever wondered why some businesses fail and others seem to go from strength to strength(越來越興旺發(fā)達(dá))? One of the major reasons for success or failure in any business is the choice of location. The ABS can be of great help in choosing the most likely place to set up your business. Whether it’s simple or a complex business.
Case study one
A Sydney doctor specializing pediatrics(小兒科) was hoping to set up a practice outside the metropolitan area, probably on the northern coast of New South Wales. He was unsure of the best place in this region and came to the ABS for help. The ABS was able to put together a report containing details of the proportion of the children in particular areas, along with information on regions with the highest birth rates. This enabled the doctor to work out where future demand for his services would be.
Case study two
A suburban retailer(零售商)in Perth owned a shoe store which stocked a wide range of shoes for men, women and children. There had been an increase in the number of similar shoe stores in the suburban shopping center and the owner wanted to assess the possibility of switching to selling imported shoes and handbags for women only. In order to ensure whether there was a market for these products, the retailer needed to obtain details of income by age, sex, and occupation for all the women in the city of Perth. Using information from the 1996 Census(普查)of Population and Housing, the ABS was able to provide this type of information in a detailed report. With the information, the retailer was able to believe that there were enough professional working women in the area with middle to high incomes, which makes his business possible.
1. What information did the Sydney doctor get from the ABS about the northern coast of New South Wales?
A. The number of medical practices there.
B. The detailed information about the children.
C. Its present and future economic situations.
D. The ideal place to start a practice there.
2. The retailer wanted to switch to selling imported shoes and handbags for women because________.
A. there were more and more working women
B. he wanted to enlarge the original store
C. there were more and more shoe stores
D. imported products were popular
3. What does the ABS do for its customers?
A. Doing research work in the fields.
B. Suggesting the most potential market.
C. Providing considerable amounts of data.
D. Predicting the possible consumer goods.
4. This passage is most probably a(n) _____________.

No Mobile Means You’re Not in Touch
My household now has four mobile phones: one for me; one each for my eldest children, the twin boys; and one for my 15-year-old daughter. Only my 12-year-old son does not (yet) have his own mobile. In other words, we’re now in line with national figures, which show that Australia has 19 million mobile phones for a population of just over 20 million people. Among 15-to 17-year-olds, nearly nine out of 10.
The reality is that a mobile phone is the coolest thing of all for a teenager to own. It’s even more important than a television, a DVD player or access to the internet. If you don’t have a mobile you are, quite literally, out of touch.
Of course, there are good and bad sides to mobiles. In my global media world, I’ve lived with a mobile switched on 24 hours a day, seven days a week, for the past ten years. At the same time, here in Perth, I started a movement on talkback radio called CAMPIR (Campaign Against Mobile Phones in Restaurants). Nothing annoys me more than people who feel that an incoming mobile call is more important than the company they are with at a restaurant or even at their dining table at home, but I believe that in the long term, we will have a revolt against the intrusion of mobiles into our personal lives.
There was a study in New Zealand last year among young teenagers that showed a quarter have used text messaging to end a relationship. Here in Australia, I’ve read of people being fired by text. That’s cold. On the other hand, lots of parents---myself included---feel their children are safer if they have their mobile with them when they are away from home.
I’ve even read that the use of mobiles among kids may mean that they smoke less. Phones are a stronger status symbol than cigarettes among children and also give them something to do with their hands.
Psychologists, though, argue that mobiles are actually a way for kids to bypass their parents. They can communicate constantly with their friends without their parents knowing anything of the conversations. No matter what the future brings, I don’t expect ever to have fewer mobiles in the house. On the contrary, the next challenge is to see if I can get through the rest of this year without having to buy a mobile phone for my youngest child.
1.According to the passage, a mobile phone is the coolest thing for a teenager to possess because _________.
A.In their opinion, the mobile phone is the most fashionable possession
B.A mobile phone is the most useful tool in the life.
C.The teenager keeps in contact with others exactly by using a mobile phone.
D.The Internet is less important than the mobile phone.
2.,Which of the following statements is true according to the passage?
A.In New Zealand most young teenagers have used text messaging to end a relationship.
B.The writer doesn’t think his children can avoid danger if they have their mobile with them .
C.The use of mobiles among kids may contribute to their less smoking.
D.Cigarettes are the strongest status symbol among children.
3.The underlined word “bypass” in the fifth paragraph probably means __________.
A. contact       B. avoid        C. inform        D. oppose
4.  It can be inferred from the passage that __________.
A. The children in the family each have a mobile phone.
B. About 60% of the children aged 15-17 have phones in Australia.
C. The writer is likely to buy a mobile phone for his youngest child this year.
D. The writer doesn’t agree that children should own a mobile phone.
