B
Here are two letters in WORKWORRIES, a column in a newspaper:

Dear Ariel,
I got a job offer from a high-tech company with a fairly satisfactory paycheck and benefits．Even the work environment is cool．But I heard that the job requires a lot of overtime and even weekends．I know it's important for newcomers to work hard to get their feet planted firmly on the ground, but I'm scared of the idea of having nearly no free time．I still need to find a girlfriend．So, shall I accept the job or give it up for another one with much less pay and more freedom?
Amoretto
Dear Amoretto,
I have two things to say: First, you're lucky to have such an excellent offer, especially at a time when so many qualified people are struggling to find any work at all; and second, you can't figure out your work-life balance until you're actually working．
Take the job．You'll be learning, doing interesting things, working in a cool environment, and making money．If you're given a contract （合同）, make sure you understand the terms before you sign．Ask your boss how many hours a week you're expected to work．If they tell you a number that is much lower than what you find once you're working, you'll be in a better position to talk to them about it．
Give your work 100 percent．Work energetically and efficiently．If you're dedicated and focused, you might accomplish more than your co-workers in less time．Showing yourself to be a productive and talented worker for the beginning will give you more bargaining power．Finally, remember that taking a job doesn't have to be a life commitment．Try to give it at least a year （two is better）．If you're really miserable after that time, look for another job that will give you more freedom．By then, you'll have workplace experience, bosses and colleagues who can speak positively about your work and some savings．Good luck!
Ariel

If you hear the sound of running water the next time you call a co-worker on his or her mobile phone, don’t be surprised. Three-fourths of Americans with mobile phones say they use them in the bathroom, a new study shows.

Approximately(大約) the same number of men and women have used the phone in the bathroom, according to a survey of 1,000 Americans by 11 mark, an integrated marketing agency, although men seem more attached to IT in the toilet: 30 percent of men versus(VS) 20 percent of women agreed with the statement, "I don't go to the bathroom without my mobile phone."

More than half the surveyed users (63 percent) said they have answered a phone call in the bathroom, and almost half (41 percent) reported initiating a phone call. That's not all, however. What goes on behind the walls of the stalls(小隔間) is anything a mobile phone is capable of. Sixty-seven percent said they have read a text, and 39 percent have surfed the Web. Men work more from the bathroom — 20 percent said they have participated in work-related calls, versus 13 percent of their female colleagues.

As expected, Gen Y(1981年后出生的一代) respondents(調(diào)查對象) are the pacesetters(先導者) in the "mobile everywhere" movement, with 91 percent using their phone in the bathroom. Still, older generations are not far behind. Eighty percent of Gen X(1961-1981) reported using the phone in the bathroom, as did 65 percent of Baby Boomers(1946-1965) and 47 percent of the Silent Generation(1925-1945).

While online, they are doing more than just surfing; 16 percent of Gen Y report they have made an online purchase while in the bathroom. Users of iPhones are particularly likely to browse and buy in the bathroom – 22 percent have made a purchase, versus 10 percent of Americans with mobile phones overall.

"The writing is on the stall," said 11 mark principal Nicole Burdette. "This study confirms what we all know: that the last private place is no longer private."

In the process, high-tech hygiene(衛(wèi)生) is taking a hit, the survey found. While 92 percent of mobile phone users said they wash their hands after using the bathroom, only 14 percent said they wash their phones.

1.Which is the best word to replace the underlined word "initiating"?

A. receiving   B. experiencing        C. ending              D. beginning

2.According to his words, Nicole Burdette mainly wants to tell us that       .

A. no wonder mobile phones are used in the bathroom

B. the bathroom is a private place for people

C. it makes people have no privacy at all

D. more men have used the phone in the bathroom

3.What does the last paragraph of the passage imply?

A. Using phones in the bathroom has a bad effect on hygiene

B. Mobile phones should not be allowed to use in the bathroom

C. Most people care about the hygiene after using the bathroom

D. Few people wash their phones after using the bathroom

4.The attitude of the author to the use of phones in the bathroom is ______

A. supportive                  B. disapproval                  C. subjective          D. objective

“I usually put my mobile phone in my bag, and I often feel like it is ringing when there actually is no phone call. Now I always want to keep it in my hand, being afraid that I might miss important calls or messages,” Miss Liu tells her doctor.

Miss Gu, a news worker, has to take her mobile phone with her all the time so as not to miss any calls from her office or readers. Gradually, she started to experience a great “panic” about her mobile phone. “Every night when I’m about to fall asleep, I often wake up with a start, feeling that my phone is ringing. Although I’m sure that I have turned it off, I still feel that it is ringing, clearly.”

The above phenomenon is what we call “mobile-phone acouasm (幻聽)”. The mobile phone has now become a “new organ” in a white collar’s daily life, and “mobile-phone acouasm” has become a common phenomenon among office workers.

According to a report of China Youth Daily, “mobile-phone acouasm ” most likely results from people’s dependency on hi-tech products. It is associated with certain professions, such as salesmen, consultants and journalists. They use mobile phones almost continuously.

Constantly being in the “stand-by” mode, the strong psychological tension gives them acouasm. Meanwhile, a large number of this year’s graduates are joining the family of acouasm suffers due to the hard job-hunting experience.

“You know that the rings are not from your phone, but you always take it out and have a look. This is subconscious (潛意識) from your body sending you a signal, telling you that you must take a break to reduce your pressure,” Professor Sun Li from Huadong Normal University explains.

There are many ways to solve the problem. The professor says that the key is to deal with pressure from work. “This is just a kind of self-protection”; the most important thing is to find out the source of your pressure. And then take part in some activities that are not related to your work. You can do anything that can relax your body and mind.

1. According to the passage the phrase “mobile-phone acouasm” refers to           .

A. people’s being addicted to mobile phones

B. people’s feeling the unreal phone rings

B. Some people develop the dependency on mobile phones.

C. Some people listen to the music on mobile phones too much.

D. Something is wrong with some people’s hearing.

3.What kind of people are more likely to suffer from “mobile-phone acouasm” ?

A. Those who use mobile phones too often.

B. Those who like mobile phones very much.

C. Those who lead a busy life.

D. Those who lead a free life.

4.What is the most important measure to deal with “mobile-phone acouasm ” ?

To what degree can a computer achieve intelligence (智力)? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet．

If you ran into Smarter Child online , you would be surprised at this kid’s huge memory．It can recite many facts． For example , Smarter Child knows every baseball player in every team this season．

He knows every word in the dictionary and the weather in every major city areas across the US．However , if you ask Smarter Child other questions , you get stranger answers．A question about Smarter Child’s age returns． “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets , “In a clean room in a high-tech building in California．”

Smarter Child uses the vast information on the World Wide Web as his memory bank．To answer questions about spelling , for instance , Smarter Child goes to American Heritage Dictionary online．For the weather , he visits www．intellicast．com．

Some scientists believe that by joining the many systems of the Internet , an artificial being with the combined knowledge of , say , Albert Einstein, Richard Nixon and Britney Spears could be born．However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A．I．, Artificial Intelligence , he must overcome two problems．

The first is that computers find it difficult to read web pages because the files are labeled in different ways．That’s why programmers need to tell Smarter Child where to look for the weather．It would be a much more difficult task to let him find it himself．

Another problem is that while Smarter Child can process (處理) information more exactly and faster than any human , he lacks common sense—a basic grounding of knowledge that is obvious to any young child．

The Future of Education

David Kelly, founder of the Design School Stanford, said, “In the classroom of the future, education will be custom-made for each student. Every child will have a laptop programmed for his or her learning style and speed. At the same time, more students will go out into the community to learn from business owners. And you’ll see more retirees in the schools as teachers.”

A New Way to Pay

Turn your cell phone into a “mobile wallet” and speed through the checkout line. With a smart phone that uses the same technology as “tap and go” cards, you’ll be able to access your financial data fast. You can select a credit or debit card（借記卡）from the screen, and then tap the phone on the checkout console（操縱臺；控制臺）.

High-Tech Guitar

A 26-year-old Australian designer has invented a brand-new way to be a rock star. The Misa Digital Guitar’s fret board looks like a traditional six-string’s but with no strings attached. There’s a touch pad （墊）where the sound hole normally is, and instead of plucking strings,（彈弦） you tap, drag, or brush the pad to “play” the instrument electronically.

The Future of Phones

Jason Chen, editor of the website gizmodo.com, makes his prediction. “Data connections will get even faster, and you’ll be linked to your environment by cell phone. Fcr example, when you go on vacation, you can point your phone at a monument（紀念碑） and it will give you information about what you’re looking at.’

Needle-Free Vaccines（無針接種）

Boston University researchers are working on a new method of inoculation（接種）—no injection necessary. A mild electrical charge from a small device, shaped like a gun, is used to drive the particles（粒子） into the body. The new idea beats the old needle method.

1.The passage mentions the following EXPECT         .
