The Overworked, Networked Family

Bring up work-and-family balance at a neighbor?s barbecue, and the conversation immediately turns toward tales of rushing out of meetings at breakneck (飞快的) speed to shuttle the kids to soccer practice or struggling to tear ourselves away for a decent vacation. Complaints about time pressure are so common that they have become a common cultural vocabulary. Everybody, it seems, is stressed out about time, and achieving “balance” has become the Holy Grail (圣杯) of middle-class family life.

But maybe balance is the wrong image. Instead, think transformation. Just as businesses are shifting from Industrial Age to networks, so, too, is the American family undergoing a parallel social revolution. Parents and children are no longer on the same schedule — unlike the way things were a generation ago. With many educated mothers and fathers working longer hours, they are linked to their kids by a web of cell phones and e-mails. At the same time, kids are taking the initiative to pursue more activities and are using information technologies to nurture their own electronic networks of relationships, from friends at school to cousins in distant cities. The networked economy is leading to far different standards and expectations of what it means to be a parent and a child. It?s not simple enough for the young to get an education. Instead, the goal is to raise children to be creative and adaptable, able both to compete successfully and to collaborate with their peers from all over the world. “We have an economy whose functioning depends for the first time on the enhancement of human capability,” says Richard Florida, professor of public policy at George Mason University in Fairfax, Va.

How can the typical overworked white-collar American — bombarded (轰炸) by e-mails, troubled with late-night meetings, and confronted with unexpected business trips — at the same time manage at high speed and cope with the new challenges at home? Gradually, a new body of shared rules-of-thumb (经验做法) is emerging, passed along at playgrounds and in offices. Among them: transform technology from an oppressor into a liberator.

Others have mastered the art of interweaving work obligations and home life in a way that was not possible before, answering an e-mail from work one minute and helping with homework the next. And the younger members of the family — already far more sophisticated at multitasking and networking than their parents — are getting a chance to see what approaches work and what falls flat. Historically, the organization of the family has mirrored, to some degree, the organization of the workplace. Take the classic middle-class family of the 1950s and ?60s, the “Golden Age” economy of strong productivity growth and abundant gains in real wages. With a secure corporate job, Dad could afford to work not much more than 40 hours a week and Mom could stay at home to raise the children. The family of that era did many things together. The classic example is eating dinner every evening at the kitchen table. The kids also followed their parents when Mom and Dad visited friends. In essence, a family acted like a single unit, with a hierarchy (等级制度) that mirrored the top-down management of factories or large industrial organizations of the day.

Fast-forward to the 2000s. Today, both Mom and Dad are more likely to have careers. The combined workweek of a husband and wife in their prime working years with children is 68 hours, up from 59 hours in 1979, according to calculations by the Economic Policy Institute. The better educated the couple, the more hours they put in. At the same time, their jobs have changed. The rote (生搬硬套) work is either being done by computers or is in the process

of being outsourced to foreign countries. Instead, what?s left are the more complicated and creative tasks that can?t be easily reduced to a set of instructions.

At home, standards for a healthy, emotionally rich family life are a lot higher than they used to be. Schedules during “leisure hours” are filled with music lessons and play dates for the kids, exercise classes for Mom, and occasional golf times for Dad. Parents are aware that colleges and universities look more favorably on high school students with a demonstrated ability to do many things well, not unlike the skills they will need in the workplace.

To achieve these goals, families are learning to turn technology to their advantage. Many time-pressed workers now realize that technology creates greater possibilities for busy families to stay in touch and, at the same time, increase family time. When Ruder went to the work on Saturdays and Sundays, he doesn?t long for “the good old days”. “Because of technology, I probably spend more time working on the weekend now, but it?s easier on me because I can work at home, then take a run, and go out to brunch with friends,” he says.

But just as excessive e-mails and conference calls fill up time on the job, there?s temptation to use the technology to stuff too much in at home as well. Other busy people have found that it?s important to maintain fairly strict boundaries between work and home.

It?s important to note that there?s no one-size-fit-all solution for the problem of reconciling long hours at work with a healthy family life. What?s more, individuals can accomplish only so much acting on their own. Schools and other major community institutions still behave as though the 40-hour workweek were the rule rather than the exception. And corporations are still loading new responsibilities and commitments onto managers and professionals, without taking away any of the old ones. Nevertheless, what?s fascinating about the current focus on managing work and family time is that it?s rooted in an abundance of possibilities. Through trial and error, with many troubles along the way, the networked family is starting to figure out how to take advantage of the many opportunities available today. And that?s progress.

1. We learn from the first paragraph that ______. A) middle-class families take achieving balance as the Holy Grail B) time pressure makes it hard for people to balance work and family

C) people are too busy to share the interesting things in their life with each other D) complaints about time pressure have become ever more common among people

energy use and institute procedures that lead to smarter and more efficient home, building and industrial plants.

Until now, wires and cables for power and connectivity have limited the widespread adoption of sensor (传感器) networks by making them difficult and expensive to install and maintain. Battery-powered wireless networks can simplify installation and reduce cost. But their high power consumption and the corresponding need for regular battery replacement has made wireless networks difficult and costly to maintain. Nobody wants to replace hundreds or thousands of window sensor batteries in a large building on a regular basis.

The promise of wireless sensor networks can only be fully realized when the wiring for both the data communication and the power supply is eliminated. Doing so requires a true battery-free wireless solution, one that can utilize energy harvested directly from the environment. To facilitate the widespread deployment of wireless sensor networks, GreenPeak has developed an ultra-low-power communication technology that can utilize environmental energy sources such as light, motion and vibration. This technology, employing on-board power management circuits and computer software to monitor energy harvesters and make the best use of harvested energy, enables sensors to operate reliably in a battery-free environment.

Wireless sensor networks deployed in our offices and home will have an enormous impact on our daily lives, helping to build a smarter world in which energy is recycled and fully utilized. These wireless platforms, equipped with advanced sensing capability, will enable us to better control our lives, homes and environment, creating a truly connected world that enables people worldwide to live in a more comfortable, safer, and cleaner environment.

62. Batteries are not an ideal energy source for sensor networks because they ______. A) require automatic recharging B) are difficult and costly to maintain C) have to be replaced from time to time D) contain metals that pollute the environment

63. Battery-free wireless sensor networks are made possible by the fact that ______. A) their maintenance has been greatly simplified B) there is energy in the environment to be utilized C) the cost of using them has been drastically reduced D) modern data communication consumes little energy

64. According to the passage, GreenPeak ______. A) supplies batteries operating on harvested energy B) benefits handsomely from communication technology C) promotes the application of wireless sensor networks D) is the first company to install wireless sensor networks

65. The focus of Paragraph 4 is on the ______. A) replacement of batteries in harvesters B) elimination of batteries in sensor networks C) impact of sensor networks on power supply

11

D) monitoring of energy harvested from the environment

66. Wireless sensor networks promise to ______. A) bring businesses high profits

C) turn motion into a major source of energy D) improve the daily lives of people worldwide

B) further develop the sensing technology

Part III Listening Comprehension

Section A

11. M: I hear you are thinking about moving back into the dorm next semester. W: Who told you that? I?d never give up my apartment. Q: What does the woman mean?

12. M: I can?t understand why Mary didn?t telephone me.

W: She did. Didn?t I tell you? She said she was sorry she couldn?t come for dinner, but hoped to be able to next time she came to town.

Q: What does the woman say about Mary?

13. W: You can change planes in either Chicago or Denver.

M: You mean there?s not a direct flight from New York to Phoenix? Q: Where does the man want to go?

14. W: Will Jim be able to come to the meeting?

M: I don?t know yet. When I phoned just now, his friend said he had taken his girlfriend out to the movies. Q: What can we learn from the conversation?

15. M: Where can I learn more about your health and fitness training program? I think I would like to join your club. I really haven?t taken very good care of myself. W: I will have you speak with the new account director. Q: What is the man going to do next?

16. W: Hello, Mr. Green. I?ve something to tell you. Would you mind if I called on you? M: Not at all. When would you like to come? Q: What does the woman want to do?

17. M: Kathy, I want to hang this new picture, do you have a hammer I can borrow? W: No. But you could use this old shoe. Q: What does Kathy suggest the man do with the old shoe?

18. W: I hope I haven?t made this dish too hot for you. M: Too hot for me? It couldn?t be. I love spicy food. Q: What does the man mean?

Now you will hear the two long conversations.

Conversation One

M: Morning, Alice. Still having problems with your faucet?

W: No, got that fixed. But I have another headache — trying to make a decision about credit cards. Well, I need one but which one?

M: Yes, that is tricky, especially since the rates are not standard.

W: That?s right. What people don?t realize is that the credit associations like Visa and MasterCard don?t issue credit cards or set terms and interest rates as individual banks do.

M: So you will need to investigate what interest rates are charged by different issuers. W: Yes, also how the rates are actually calculated, I think.

M: Alice, you should remember to ask them what rules you must follow to maintain these rates. If you don?t pay off your bill, all new charges will begin rising immediately.

W: Yes, that?s another problem and banks charge varying amounts for annual membership, late payments and exceeding your credit line.

M: You know, I read somewhere that 70% of people with credit cards pay interest on their purchases and only about 2% of the cardholders knew the interest rate they were being charged. Nearly all credit card debt carries an interest rate of 24% or more.

W: Wow, I guess I should ask a few hard questions.

Questions 19 to 21 are based on the conversation you have just heard. 19. What’s the woman’s problem?

20. Why is it important for the woman to know her grace period? 21. What will the woman probably do next?

Conversation Two M: Hi, Susan, do you have anything planned for this Saturday? W: Uh, I?m kind of busy. Why do you ask?

M: Oh, I was wondering if you?d like to get together and do something, like watch a movie or take a walk down by the lake.

W: I?d love to, but I?m really going to be busy all day on Saturday. M: What do you have going on that day? W: First, my mom asked me to help clean the house in the morning, and then I have a dentist appointment at 12:30. I can?t miss that because I?ve canceled twice before. M: Well, what about after that? W: Well, I?m going to be running around all day. After the dentist appointment, I need to meet Julie at 2:00 to help her with her science project that?s due on Monday morning at school. M: Okay, but are you free after that?

W: Hardly. Then I have to pick up my brother from soccer practice at 4:30, and my mom asked me to cook dinner for the family at 5:30. I feel like a slave sometimes. Then, I have to clean the dishes and finish reading my history assignment. Who knows how long that?ll take.

M: Wow, sounds like you?re going to have a full day. Hey listen, why don?t I come over later in the evening, and we can make some popcorn and watch a movie.

18

W: Oh, that?d be great, but our video machine is broken. M: Huh. Well, let?s just play a game or something.

W: Sounds good, but give me a call before you come. My mom might try to come up with something else for me to do.

Questions 22 to 25 are based on the conversation you have just heard. 22. Where does Susan have to go at 12:30? 23. When is Susan going to meet Julie? 24. What will Susan do after she cooks dinner?

25. Why can’t the speakers watch a video at Susan’s house?

Section B

Passage One

Next time you bring your kids in for a checkup, don?t be surprised if the doctor asks about their tastes and entertainment. The American Academy of Medicine suggested last week that doctors work with parents to evaluate how much TV kids watch and what they see, what video and computer games they play, which websites they visit on the internet, whether they play, website they visit on the Internet, whether they view R-rated videos with the company of their parents, what music they like and what books they read. Doctors are worried that kids who spend too much time in front of the tube don?t get enough exercise and can become overweighted. The Academy is also concerned that the message the kids get from entertainment media can make them more violent and sexually active. The Academy recommends that children under age two not watch any TV. “Children need activities to stimulate the brain during the first two years of life”, says Doctor Marien Barren, who chair the Academy?s Committee on public education. “They need feedback and socialization. Older children,” she says, “should watch TV in a common area. Their bedrooms should be electronic media free zones where they could have a quiet place to read, study, play or just relax.

Questions 26 to 28 are based on the passage you have just heard. 26. What unusual question may doctors ask when giving kids a checkup next time? 27. What does the academy suggest children under age two should do? 28. What do we learn about children’s bedrooms from the report?

Passage Two

An allowance is an important tool for teaching kids how to budget, save and make their own decisions. Children remember and learn from mistakes when their own dollars are lost or spent foolishly. How large an allowance is appropriate? Experts say there is no right amount. Actual amounts differ from region to region, and from family to family. To set an appropriate allowance for your child, work up a weekly budget. Allow for entertainment expenditures such as movies and snacks. Next, include everyday expenses such as lunch money, bus fare, and school supplies. “If you make the child responsible for these ?bills?,” says Josephine Swanson, a consumer specialist, “he or she will learn to budget for necessary expenditures.” Finally, add some extra money to make saving possible. If you can, keep your child?s allowance in line with that of his friends. A child whose purchasing power falls away below his peers can feel left out. It can be tough, but avoid excusing your children when they make a mistake with their allowance. Experts advise that an allowance should not be tied directly to a child?s daily chores. Kids should help

19

around the house not because they get paid for it but because they share responsibilities as members of a family. You might, however, pay a child for doing extra jobs at home, which can develop his or her initiative. Questions 29 to 31 are based on the passage you have just heard. 29. What is the passage mainly about?

30. What do the experts say about the appropriate allowance for a child? 31. What do experts advise?

Passage Three

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology. With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today?s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.

In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on — in much the same way our bodies make new skin cells to take the place of old ones. It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future. Questions 32 to 35 are based on the passage you have just heard. 32. Which is the main cause for human death now according to the passage? 33. In the speaker’s opinion, in which aspect does today’s most important advance in technology lie? 34. Why humans may live longer in the future? 35. What can we learn from the passage?

Section C Pocket electronic dictionaries, popular with students, are raising concern among local educators. Used primarily by students studying English, it contains dictionaries and general information. The products range in price from several hundred yuan to several thousand, depending on the functions “The electronic dictionary lightens both my school bag and my work load,” said a middle school student. “Most of my classmates use electronic dictionaries for the convenience.” he said.

Even some teachers defend electronic dictionaries. “Electronic dictionaries often allow students to read more,” said an English teacher. “they prefer to look up words they don?t understand without having to leaf through a dictionary. They often find ordinary dictionaries are too complicated.”

20

However, educators have expressed some concerns about the potential risks of allowing students to use these products.

“The definitions are simplified and somewhat unclear compared with those in ordinary print dictionaries” said an official with an education commission. “Most of these devices do not include sample sentences which are of vital importance if a student is to learn correct usage.” he said.

Another teacher provided an amusing example of what can happen when a student does not use a proper dictionary. “One of my students wrote in a composition ?He asked her to marry him, but she garbaged him,? he said. I questioned him about his use of the noun ?garbage? in this context and discovered that he wanted to use the verb ?refuse?, but he was not sure of its meaning, then he looked it up in a cheap dictionary, and saw refuse garbage!
