Third-generation mobile phones, known as 3G, are the next big step for the telecom(電信) industry. Data speed in 3G networks is much quicker than that in present technology. This means users can have high-speed Internet access(上網(wǎng)) and enjoy video and CD-quality music on their phones.
"Mobile data is not a dream; it's not an option(選擇) but a requirement" said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.
With 3G, you can forget about text messages telling you yesterday's news; a 3G phone can receive video news programs, updated(更新) four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home. 
Don't worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset(手持機(jī)).
However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.
Many European countries have already launched the service. In May 2000 the US Government issued five licenses(許可證) to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.
International telecom companies can't wait to sell 3G in China, the world's largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.
“We need to create a pool of 3G customers before the large-scale commercial launch(開始) of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “We expect that the 3G licenses will be issued(發(fā)行) late next year.”
We'll also see 3G services enter our daily lives in all-sorts of new ways, from shopping and banking to playing interactive computer games over the net. It won't be long before we think nothing of sitting on a train using a mobile palmtop(掌上型電腦) to check our bank accounts or pay bills. You might even click on an icon(圖標(biāo)) on the screen to set up an immediate video-conference with your bank clerk.
67. 3G is ______.
A. a kind of mobile phone that can send text message and make calls
B. a kind of technology that makes mobile data and video calling come true
C. a kind of player that can be used to listen to CD or MP3 music
D. a kind of system that makes it easy to surf the Internet
68. What does Len Lauer want to inform the readers?
A. Realizing the dream of mobile data based on the application of 3G is a must.
B. There is no need to send messages since 3G can receive video news programs.
C. 3G is supposed to own all the functions that a computer has.
D. It is a choice to carry mobile data with 3G phones.
69. The 3G services can be launched after the following steps EXCEPT that ________.
A. they have to test its 3G-based technologies, networks and services
B. they need to create a group of 3G customers
C. the 3G licenses are issued and 3G phones are tested
D. international telecom companies decide to sell 3G in China
70. The last paragraph shows us that ________.
A. 3G services bring a lot of convenience to us
B. we cannot live without 3G mobile phones
C. 3G services can change our life completely
D. 3G services will take the place of other technologies

STEVE Wayne, 16, who worked this summer as a lifeguard and swim teacher in Idaho Falls, was thrilled to see an extra $20 in his paycheck when the federal minimum wage increased in July.
“When you’re getting paid minimum wage, anything helps, ” Wayne said.Wayne is one of several hundred thousand American teenagers who earn the minimum wage. The last of three recent increases that took the minimum from $5.15 an hour in 2007 to $7.25.U.S. Secretary of Labor Hilda Solis says the minimum-wage increase will pump an extra $5.5 billion into the economy over the next year, which is helpful at a time when the economy is hurting.
"You're giving people who spend money a raise," says Kai Filion of the Economic Policy Institute. "Those people will go out and spend that money, and it will circulate through the economy."
But other economists say raising the minimum wage actually hurts the very people it's designed to help. A higher hourly minimum, they say, could force businesses to cut workers' hours, or even lay people off.
"What matters for people earning minimum wage is how much money they take home, in total, in their paycheck," explains Rajeev of Georgia State University's Economic Forecasting Center. "Their hourly rate may go up, but their number of hours may come down, so it's not an overall increase."
Business owners also say that raising the minimum wage exerts（施加）upward pressure on other wages. "If the minimum wage is $7 and I have to pay $8 or $9 to hire a dishwasher, then the cooks are going to say they want more," sayd Cleveland restaurant owner Rick. "How much can I charge for that hamburger?"
Another argument is that it makes it more expensive for businesses to hire new workers. For many businesses already struggling to make ends meet in these tough times, it will be simply too expensive to keep or to hire new people.
55．Steve Wayne was excited that_____________ .
A．his hard work had paid off
B．he had received a big wage increase
C．he has more money due to an increase in minimum wage
D．the wages of American teenage workers have been increased
56．According to the text, the US federal government has increased minimum wage with the aim of__________
A．decreasing unemployment
B．promoting economic recovery
C．increasing American teenagers’ wage
D．narrowing the gap between the rich and the poor
57．What matters most to people in need of help is_____________.
A．a(chǎn) higher hourly minimum       B．more working hours
C．a(chǎn) minimum-wage increase      D．a(chǎn)n increase in total income
58．Some are against the increase in minimum wage because they say_____________.
A．only very few workers will be helped
B．they have to cut down working hours
C．many business owners can’t afford to employ new workers
D．minimum wage workers will expect more pay rises in the future

第三部分:閱讀理解
What happens to old school buses when they can no longer safely carry kids to school? Most go to waste factories to be changed into pieces of metal. But a few of the old vehicles (車輛) find new lives in the center of Africa. Most of those buses end up on the streets of Kinshasa, the capital of the Democratic Republic of Congo.
The Kinshasa buses are that yellow color, which makes them stand out (突出) in the city’s heavy traffic, but the buses don’t look at all as they did in the United States. In Kinshasa their taillights(尾燈) are almost all missing or broken. They don’t obey traffic rules and often race around the city very fast. The buses compete with motorcycles, cars, trucks, and other vehicles for space on the road. They make loud sounds when moving, and they are packed with people carrying loads of goods, such as fish, milk, beans and onions.
However, Kinshasa business people love the old, yellow buses, which they buy from American companies, because the vehicles are strong, reliable (可依靠的) and inexpensive. A used bus sells for about $2,000 in Congo. A new bus is more expensive. In the United States, a new school bus with all its lights working costs about $80,000.
The fare (票價(jià)) to travel across the city is usually about 30 US cents. “Transport is a big problem in Kinshasa,” says passenger Bruce Kingambo. “But the yellow buses help people here get around.”
56．The underlined sentence in the first paragraph means “In the center of Africa some old US     school buses can be_________.”
A．useful                     B．expensive                C．free                        D．new
57．Before the school buses leave America for Congo, they_________
A．have broken taillights
B．don’t obey the traffic rules and move at full speed
C．carry many people and goods
D．don’t compete with other vehicles
58．How many used buses can you buy in Congo for the price of a completely new school bus     in the USA?
A．10.                         B．20.                         C．30.                         D．40.
59．The passage mainly tells us _________
A．how to use old school buses
B．a(chǎn)bout new lives for old school buses
C．to try to take old school buses
D．how to drive old school buses

We typically associate the word “science” with a person in a white coat doing experiments in a laboratory. Ideally, experiments should play as big a role in the human sciences as they do in the natural sciences; but in practice this is not usually the case. The are at least three reasons for this.
1．Human scientists are often trying to make sense of complex real world situations in which it is simply impossible to run controlled experiment.
2．The artificiality of some of the experiments that can be conducted may make the behavior of the participants abnormal.
3．There are moral reasons for not conducting experiments that have a negative effect on the people who participate in them.
Faced with the above difficulties, what are human scientists to do? One solution is to wait for nature to provide the appropriate experimental conditions. We can, for example, learn something about how a normal brain functions by looking at people who have suffered brain damage; and we can gain some understanding into the roles played by genes and the environment by studying twins, who have been separated at birth and brought up in different families. In the case of economics, economic history can provide us with a bank of-admittedly not very well-controlled-experimental data.
However, human scientists do not just sit around waiting for natural experiments to arise. They also think of some experiments of their own. Suppose you want to know how a baby sees the world. We cannot, of course, ask the baby since it has not yet learnt to speak. So it might seem that all we can do is guess. People usually won’t change their mind until it was found out that babies tend to stare at surprising things longer than at unsurprising ones. This key understanding was like opening a window on to the developing mind. There was now a way of testing babies’ expectations and getting some idea of how they are six months old, babies can already do the following things: figuring out that objects consist of parts that move together being aware of the difference between living and non-living things and even doing simple arithmetic work.
60．What is true about the natural sciences and the human sciences according to this passage?
A．Both human scientists and natural scientists can run controlled experiments.
B．Experiments done by human scientists and natural scientists are artificial.
C．Both human and natural science experiments should be of the same importance.
D．It’s not moral to conduct human science experiments.
61．What do we know about human scientists from this passage?
A．They are white coat scientists.
B．They have more experimental sources than natural scientists.
C．They conduct experiments passively.
D．They face more difficulties in carrying out their research.
62．Which of the following experiments belongs to human science experiment?
A．Vinegar Volcano Vinegar and baking soda make. for a fun and easy science experiment. Try creating a vinegar volcano.
B．Taste Without Smell Put your senses to the test with this simple experiment that shows the
importance of your sense of smell.
C．Lung Function Observe your breath and confirm your lung volume by completing this experiment.
D．Make a Rainbow Use sunlight and water to make your own rainbow with this cool experiment
that will teach kids how rainbows work while they enjoy a fun activity
63．What does the author tell us in this passage?
A．ABCs about the science experiment.
B．Some knowledge of science.
C．Some differences between the human sciences and the natural sciences.
D．The similarity of the natural sciences and the human sciences.

“I find myself glancing at my watch to see how long I’ve been standing in line,” she said. “Everywhere I go, I notice if the dumpster(垃圾罐)gates are open or if there’s trash in the parking lot.” Ms. Clark is a “mystery shopper”, one of thousands of contract workers that companies hire to pretend as regular customers in order to judge customer service, cleanliness and whether a store is selling a product that meets company specifications (規(guī)格).
Mystery shoppers can be found or, rather, not found, everywhere from restaurants and automotive shops to convenience stores and department stores. They play a constant cat-and-mouse game with store and restaurant employees and managers. However it’s not all fun and games. Once in the field, a mystery shopper will typically visit several stores or restaurants per hour, taking mental notes while inside, then jotting down physical notes after they leave.
It’s important for mystery shoppers to be as exact as possible, because the client companies are looking for data they can use to improve their service. The questionnaire won’t say, “Does the trash can need to be emptied?” What an educated shopper will say is, “The trash can to the left of the front door was overflowing with 10 pieces of trash on the ground.” Companies don’t need opinion but facts.
Nowadays mystery shoppers are armed with a number of high-tech devices, such as a digital scale and a digital thermometer, as well as a handheld PC for recording the entire experience. It’s a challenging job but a rewarding one. Mystery shoppers can be full time or part time, but the full-time workers tend to stick to standard mystery shopping while part-timers often choose the less complex reward-based programs. In those , the shoppers stay disguised(裝扮的) only until the “shop” is finished, and then reveal (透漏) themselves to the store management and award prizes to employees who provided excellent service.
To be a mystery shopper, it’s important to be a good observer, but sometimes it’s important to have the right profile(外表), too. Companies often hire shoppers from particular backgrounds to better blend in with clients’ regular customers. If a secret shopper will be sent in, for example, to do a high-end automotive shop, the candidate must have a particular profile that meets a high-end, luxury car-type buyer profile. “It’s a challenge to perform your shop without being discovered,” Ms. Clark said, “because most of the people that we work for are very aware of the mystery shopping program.”
67. According to the text a “mystery shopper” would not have to        .
A. sign a contract with the employer     B. travel a lot around the city
C. provide exact facts to the company D. fill in questionnaires  
68. We learn from the text that Ms. Clark        .
A. visits some shops regularly and sometimes does something special
B. pretends to be a shopper and evaluates the services
C. is a government official looking into the services
D. is a manager of a company offering good services
69. People are willing to become a mystery shopper mainly because they can        .
A. get the best service and get paid at the same time
B. play a cat-and-mouse game with shop employees and managers
C. do the job either full time or part time and get paid well
D. observe clearly what happens in the shops
70. What does the underlined word “those” in the 4th paragraph refer to?
A. The shops where the mystery shoppers go.      
B. The less complex reward-based programs.
C. Part-time jobs.             
D. Excellent services.

It might have been a really bad stressful day, feeling trapped inside by the cold and snow which surrounded us. My husband was the first to shift his consciousness. He dressed accordingly and announced that he was going outside to build a giant snowman.
At first he stood alone, piling massive amounts of snow. Soon after a neighbor joined in my husband’s quest to embrace the opportunity the winter presented. Maintaining less than desirable attitudes, we reluctantly put on our snow gear(用具) and headed outside. It wasn’t long before we were smiling and enjoying the abundance of snow that Mother Nature had provided. Others came to our yard one by one to give a hand in the making of our giant snowman.
In the end we all stood back and marveled at what we had created. He was eleven feet high, twenty-five feet around at the base and decorated with many household items supplied by various families. There he stood, our glorious, gigantic (巨人般的) snowman.
People drove by and smiled. Some even stopped to enjoy his existence. The spirit that went into creating him seemed to catch on and we all enjoyed it while the cold temperatures allowed.
With the passing of time, the spring made its way back into our yard and the snowman changed form considerably. In a final effort to save what we created for just a little bit longer somebody stopped by and changed the snowman’s remains to look like a rabbit.
As I prepared for the start of another week, I decided to check my email before going to bed. I found a curious message that contained the subject line: enjoy the snowman. I decided to read the message even though I did not recognize who sent it. The words it contained melted my heart.
The email said: … your neighbor looks on in disbelief! I am sure you people are enjoying the sounds and smells, along with sights of spring. The energy displayed in Mr. Snowman or Ms, is filled with vigor and joyous energy. You and your family keep it up, as this is what the world needs now. Love sweet love. More power to you and your loved ones, keep sharing with the world around.
Perhaps it was more than snowman we built that day. I’d like to agree that it was. The message seems clear. Our circumstances will turn out to be what we make of them. The possibilities are endless and the choice is ours.
60. How did the author plan to spend that cold day at first?
A. By having a busy day.      B. By staying at home. C. By building a snowman.   D. By visiting neighbors.
61. The reason for her husband to make a snowman was that ________.
A. he had to please his neighbors                       B. he was better at it than others
C. he wanted to cheer himself up                       D. he must get the last chance before spring
62. From the passage we can know that the snowman_______.
A. was built only by the author’s family            B. was surprisingly big in size
C. made people more forgiving                   D. made building snowman popular
