Some families in America and elsewhere have started buying child friendly mobile phones ou

tfitted with GPS (Global Positioning System) technology.

These phones and their related tracking services allow parents to pinpoint the location of their children with ease. Parents agree to pick up the phone bill in return for the reassurance of knowing where their children are; children are prepared to put up with the watching if they are allowed to have a phone.

Mobile operators in America are now launching tracking services. Under a federal decree known as E911, they had to upgrade their networks to ensure that anyone dialing the 911 emergency number could be located to within 100 metres. Some operators opted for triangulation technology, which determines the location of the handset by comparing the signals received by different base stations. But Verizon and Sprint chose to adopt the more expensive but more accurate GPS technology instead, and are now looking for ways to make money from it.

Verizon calls its service "Chaperone". For $10 a month, parents can call up the location of their child's LG Migo handset from their own mobile phones, or from a PC. The child receives a message saying that the handset's position has been requested, and the parents receive an ad dress, or a marker on a web-based map, giving the child's location. For an extra $10 per month, they can sign up for Child Zone, a service that, among other things, fires off an alert when a youngster (or, at least, the youngster's handset) strays outside a specified area.

For its part, Sprint has launched a similar service that can also let parents know when a child arrives at a particular location.

Another location service is available from Nextel, a mobile operator that was taken over by Sprint in 2005. Nextel opened up some of its systems to enable other firms to build their own software and services on top of its GPS technology. One example is AccuTracking, a small company which offers a tracking service for $6 a month and boasts that it is "ideal for vehicle tracking" or to keep "virtual eyes on kids". Some customers are also using the service to track their spouses, by hiding phones in their cars. "Mine is hidden under the hood, hot-wired to the battery—it works very well and it is easy to hook up continuous power, "writes one customer on AccuTracking's message board.

Start-ups are working on everything from city-wide games of hide-and-seek to monitoring the locations of Alzheimer's patients. Services that monitor jogging routes, and work out distance travelled and calories consumed, might also prove popular.

As a result, mobile operators, handset-makers and start-ups could transform. and expand a small, specialist market so far dominated by expensive, dedicated tracking systems.

The tracking function of the mobile networks was probably first intended for ______.

A．federal officials

B．national security

C．parent consumers

D．emergency rescue

听力原文： The United States is full of automobiles. There are still many families without cars, blt some families have two or even more. However, cats are used for more than pleasure. They are a necessary part of life.

Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.

Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile from the school. When the children are too young to walk that far, their mothers take turns driving them to school. One mother drives on Mondays, taking her own children and her neighbors' children as well. Another mother drives on Tuesdays, another on Wednesdays, and so on. This is called "forming a car pool". Men also form. car pools, with three or four men taking turns driving to the place where they all work. More cur pools should be formed in order to put fewer automobiles on the road and to use less gasoline. Parking is a great problem, and so is the traffic in and around cities. Too many cars are being driven. Something will have to be done about the use of cars.

(23)

A．To get supplies.

B．To get to their jobs.

C．To carry their products.

D．To enjoy themselves.

听力原文： One of the biggest problems in developing countries is hunger. An organization called Heifer International is working to improve the situation. The organization sends farm animals to families and communities around the world. Pal American farmer Dan West developed the idea for Heifer International in the 1930s. Mr. West was working in Spain where he discovered a need for cows. Many families were starving because of the Civil War in that country. So Mr. West asked his friends in the Unites States to send some cows. The first Heifer animals were sent in 1944. Since that time more titan 4 million people in 115 countries have had better lives because of heifer animals. To receive a Heifer animal, families must first explain their needs and goals. They must also make a plan which will allow them to become selfsupporting. Local experts usually provide training. The organization says that animals must have food, water, shelter, health care and the ability to reproduce. Without them, the animals will not remain healthy and productive. Heifer International also believes that families must pass on some of their success to others in need. This belief guarantees that each person who takes part in the program also becomes a giver. Every family that receives a Heifer animal must agree to give that animal's first female baby to other people in need. Families must also agree to pass on the skills and training they receive from Heifer International. This concept helps communities become selfsupporting.

(33)

A．He was interested in the study of wild animals.

B．He started the organization Heifer International.

C．He was wounded in the Spanish Civil War.

D．He sold his cows to many countries in the world.

听力原文： A "typical" British family used to consist of mother, father and two children, but in recent years there have been many changes in family life. Some of these have been caused by new laws and others are the result of changes in society. For example, since the law made it easier to get a divorce, the number of divorces has increased. In fact one marriage in every three now ends in divorce. This means that there are a lot of one-parent families. Society is now more tolerant than it used to be of unmarried people, un married couples and single parents.

Another change has been caused by the fact that people arc living longer nowadays, and many old people live alone following the death of their partners. As a result of these changes in the pattern of people's lives, there are many families that consist of only one person or one person and children. You might think that marriage and the families are not so popular as they once were. However, the majority of divorced people marry again, and they sometimes take responsibility for a second family.

(33)

A．High rate of divorce in Britain.

B．Generation gap in Britain.

C．Changes in family life in Britain.

D．One-parent families in Britain.

听力原文： For good or bad, computers are now part of our daily lives. With the price of a
small home computer now being lower, experts predict that before long all schools and businesses and most families in the rich parts of the world will own a computer of some kind. Among the general public, computers amuse strong feelings--people either love them or hate them.

The computer lovers talk about how useful computers can rein business, in education and in the home--apart from all the games, you can do your accounts on them, use them to control your control heating, and in some places even do your shopping with them. Computers, they say, will also bring some leisure, as more and more unpleasant jobs are taken over by computerized robots.

The haters, on the other hand, argue that computers bring not leisure but unemployment. They worry, too, that people who spend all their time talking to computers will forget how to talk to each other. And anyway, they ask, what's wrong with going shopping and learning languages in classroom with real teachers？ But their biggest fear is that computers may eventually take over human, beings altogether.

(28)

A．Computers have become part of our daily lives.

B．Computers have advantages as well as disadvantages.

C．People have different attitudes to computers.

D．More and more families will own computers.

Section B

Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.

听力原文： Food is a basic necessity, so every culture has important norms and customs related to it. Ever since they adopted settled lifestyles centuries ago, most cultures have emphasized daily meals in households or family units. Some members provide the food, some members prepare the food, and all members must eat. The providers and the preparers may not be the same, depending partly on gender roles and specialization. And the status of individuals in the eating process may not be the same, depending partly on their age and gender, and whether the household contains servants or guests. Servants rarely eat with others, while honored guests may be wined and dined like visiting royalty. Elders and males may also be treated ceremonially.

Eating away from home in restaurants, inns, or hotels has long been an option in most cultures, but the variety of these choices is rapidly increasing today as the fast pace of modern life encourages more people to "eat on the run". This also tends to blur the traditional distinction between providers and preparers of food, especially in families where both parents work full time outside the home. In such eases both parents may eat out at noon, the children may eat at school, and anyone may pick up pizza or hamburgers on the way home or phone for pizza to be delivered. In the US, Chinese restaurants do a big take-out business and microwaved "TV dinners" are very popular. Some busy families rarely eat formal meals together, ever when they all eat at home.

(27)

A．Gender roles and specialization.

B．Social status and age.

C．Where and when the meal is provided.

D．The kinds of meals.

第11题

As long as her parents can remember, 13-year-old Katie Hart has been talking about going t
o college. Her mother, Tally, a financial-aid officer at an Ohio university, knows all too well the daunting calculus of paying for a college education. Last year the average yearly tuition at a private, four-year school climbed 5.5 percent to more than $17,000. The Harts have started saving, and figure they can afford a public university without a problem. But what if Katie applies to Princeton (she's threatening), where one year's tuition, room and board — almost $34,000 in 2002 — will cost more than some luxury cars？ Even a number cruncher like Tally admits it's a little scary, especially since she'll retire and Katie will go to college at around the same time.

Paying for college has always been a humbling endeavor. The good news: last year students collected $74 billion in financial aid, the most ever. Most families pay less than full freight. Sixty percent of public-university students and three quarters of those at private colleges receive some form. of financial aid — mostly, these days, in the form. of loans. But those numbers are not as encouraging as they appear for lower-income families, because schools are changing their formulas for distributing aid. Eager to boost their magazine rankings, which are based in part on the test scores of entering freshmen, they're throwing more aid at smarter kids— whether they need it or not.

The best way to prepare is to start saving early. A new law passed last year makes that easier for some families. So-called 529 plans allow parents to sock away funds in federal-tax-free-investment accounts, as long as the money is used for "qualified education expenses" like tuition, room and board. The plans aren't for everyone. For tax reasons, some lower-and middle-income families may be better off choosing other investments. But saving is vital.

Aid packages usually come in some combination of grants, loans and jobs. These days 60 percent of a ll aid comes in the form. of low-interest loans. All students ate eligible for "unsubsidized" federal Stafford loans, which let them defer interest payments until after graduation. Students who can demonstrate need can also qualify for federal Perkins loam or "subsidized" Staffords, where the government pays the interest during school.

Traditional scholarships, academic or athletic, are still a part of many families' planning. Mack Reiter, a 17-year-old national wrestling champion, gets so many recruiting letters he throws most away. He'll almost certainly get a free ride. Without it, "we would really be in a bind," says his mother, Janet. For everyone else, it's worth the effort to pick through local and national scholarship offerings, which can be found on Web sites like collegeboard. com.

What does the author intend to illustrate with the example of the Harts？

A．The difficulty of paying the tuition.

B．The increasing tuition in the university.

C．The far-sight of the parents.

D．The promising future of Katie.
