Gauri Nanda sees a wearable computer as a handbag—one that’s built out of four-inch squares and triangles of fiber, with tiny computer chips embedded(嵌入) in it. It looks, feels and weighs like your typical leather purse.
That’s where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf.
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
Here’s how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will notify the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring—and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years--- making for a booming market for wearable computers that don’t like something out of science fiction.Which of the following describes a wearable computer?

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their ears, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries (食品杂货) saving us from having to walk long distances from where we live.
I was so grieved that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that，several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick ii up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity (人性) as a whole. And it has influenced (影响) us to be more mindful of ways we, too, can share with others. No matter how or how small, an act of kindness shows that someone cares. And the results can be everlasting.Why was the bike so important to the couple?
| A．The man's job was bike racing. | B．It was their only possession. |
| C．It was a nice Kona 18 speed. | D．They used it for work and daily life |
We can infer from the text that ________
| A．The couple worked 60 hours a week | B．people were busy before Christmas |
| C．the stranger brought over the bike | D．life was hard for the young family |
How did people get to know the couple's problem?
| A．From radio broadcasts. | B．From a newspaper. |
| C．From TV news. | D．From a stranger. |
The underlined word "grieved" in paragraph 3 probably means________.
| A．upset | B．pleased | C．frightened | D．lucky |
What do the couple learn from their experience?
| A．Strangers are usually of little help. | B．One should take care of their bike. |
| C．News reports make people famous. | D．An act of kindness can mean a lot. |
Societies all over the world name places in similar ways. Quite often there is no official naming ceremony but places tend to be called names as points of reference by people. Then an organized body steps in and gives the place a name. Often it happens that a place has two names: One is named by the people and the other by the government. As in many areas, old habits died hard, and the place continues to be called by its unofficial name long after the meaning is lost.
Many roads and places in Singaporeare named in order that the pioneers will be remembered by future generations. Thus we have names such as Stamford Road and Raffles Place. This is in keeping with traditions in many countries ---- in both the West and the East.
Another way of naming places is naming them after other places. Perhaps they were named to promote friendships between the two places or it could be that the people who used to live there were originally from the places that the roads were named after. The mystery is clearer when we see some of the roads named in former British bases. If you step into Selector Airbase you will see Piccadilly Circus ---- obviously named by some homesick Royal Air Force personnel.
Some places were named after the activities that used to go on at those places. Bras Basah Road is an interesting example, “Base Basah” means “wet rice” in Malay. Now why would anyone want to name a road “Wet Rice Road”? The reason is simple. During the pioneering days, wet rice was laid out to dry along this road.
A few roads in Singapore are named by their shapes. There is “Circular Road” for one. Other roads may have part of their names to describe their shapes, like “Paya Lebar Crescent”. This road is called a crescent（月牙） because it begins on the main road, makes a crescent and comes back to join the main road again. We learn from Paragraph 1 that _____.
| A．the government is usually the first to name a place |
| B．a ceremony will be held when a place is named |
| C．many places tend to have more than one name |
| D．people prefer the place names given by the government |
Which of the following places is named after a person?
| A．Raffles Place. | B．Selector Airbase. |
| C．Piccadilly Circus. | D．Paya Lebar Crescent. |
What does the underlined phrase “die hard” in Paragraph 1 probably mean?
| A．Change suddenly. | B．Change greatly. |
| C．Disappear quickly. | D．Disappear very slowly. |
Bras Basah Road is named _______.
| A．after an activity | B．after a place |
| C．after a person | D．by its shape |
What can be inferred from the passage?
| A．The way Singaporeans name their places is unique. |
| B．Some places in Singapore are named for military purposes. |
| C．Some place names in Singapore are the same as in Britain. |
| D．Young Singaporeans have forgotten the pioneers. |
A young boy was sitting in the back seat of the car eating an apple. He asked his father, “Why does my apple turn brown?” his father answered, “When the skin is removed, air reaches the flesh of the apple and causes oxidation. This changes the apple’s molecular structure and results in a brownish color.” The boy asked, “ Daddy, what are you talking about?”
I know how that boy feels. Sometimes I want answers to some of those confusing questions that we all meet with, such as how to get through difficult times or what to do in a tough situation. I just want to get it right.
The problem is that I don’t always have the answer I need. Nobody else seems to have them, either. So I go on making mistakes and think that I’ll never get it right.
Often I didn’t know what to do. I often made poor choices, but I gradually improved. Then I realized that I don’t HAVE TO always get it right. I don’t have to always know what to do all the time. All I really need to do is try my best, learn from my mistakes and go on.
Dr. Leo Buscaglia once said, “ No one gets out of this world alive, so the time to live, learn, care, share, celebrate and love is now. That would be pretty hard to do when you’re waiting for all the answers first.”
So you got it wrong. You made a mistake. So what should you do next? Forgive yourself and try again. You may not get out of this world alive, but you can get plenty of life out of this world if you are not too worried about always getting it right. In the beginning, the author tells the story of a boy and his father to ____.
| A．show that the father is very knowledgeable |

Technology is making life easier for some dairy farmers．They use robotic systems to milk their cows．Cows are trained to follow a series of paths that lead to milking stations．Only one cow at a time can enter a station．
Once inside，the cow is rewarded with food．As the cow eats，a robotic arm cleans and connects the animal to the milking machine．A few minutes later，milking is complete．The gate is opened，the cow is released and the next cow enters．
The robotic systems are designed to operate 24 hours a day．The cows get to decide when they want to be milked．Cows are milked an average of about three times a day．Some are milked four to six times a day．
The cows wear collars around their necks that identify them to the system．A computer keeps records on their eating and milking．A cow is released from the station if the computer decides it should not be milked．
The automated system also measures the temperature and color of freshly produced milk．Milk is thrown away if it does not pass the tests．
Professor Plaut believes the systems will appeal（吸引） especially to the next generation of farmers．She means young people who are more interested in technology and less interested in working all the time on the farm．Still，she says the price of robotic milking systems will continue to limit their use．
Doug and Tina Suhr have more than 100 cows on their family farm．Last year it became the fourth farm in southeast Minnesota to get a robotic milking system．A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars．The second cost 150 000．
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot．He says the increase in milk production reaches a high of more than six kilograms per cow per day．From the first paragraph，we can infer________．
| A．the robotic system is designed to reduce labor |
| B．cows can be raised by robots in the future |
| C．robots direct cows into milking stations |
| D．cows are kept clean by robots on some farms |
Besides milking cows，the robotic system also can______．
| A．adjust the temperature of milking stations |
| B．judge the quality of fresh milk |
| C．improve the appetite of cows |
| D．keep fresh milk for two weeks |
Why is the robotic system not popular now?
| A．Because young people have no interest in it． |
| B．Because it is difficult to learn how to use it． |
| C．Because people can’t afford to buy it． |
| D．Because it usually causes the waste of milk． |
According to Doug，what is the wage of an employee?
| A．150 000～170 000． | B．750 000． |
| C．150 000～30 000． | D．30 000—32 000 |
The best title for the passage may be_________．
| A．Letting robot milk your cow | B．Milking cows by hand |
| C．Improving the quality of milk | D．Drinking fresh milk every day |
Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. He took a short business course, and went to work as a salesman in a large city.
Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.
Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.
By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always run his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.” Frank took a short business course in order to _________.
| A．get away from the farm | B．learn something from a salesman |
| C．earn more money for his family | D．get enough to eat. |
Frank sold the odds and ends quickly because _________.
| A．he had put the goods on a table in a very nice way. |
| B．he cut down the price by half |
| C．he knew how to get people to buy his goods. |
| D．the sign he put on the table was well designed. |
The price of the knives was cut down by half because ________.
| A．the factory workers worked 24 hours a day. |
| B．knives were ordered in large quantities directly from the factory. |
| C．the knives were made in Germany, where labour was cheap. |
| D．the knives were produced in one factory. |
________ make Woolworth a world-famous man.
| A．His business skills and his wealth |
