Can hard work be replaced by machines in agriculture? Yes, man is trying out automatic (自动化) farming. It is fun to watch a machine picking tomatoes. The strange machine sails like a ship across a sea of plants. In its front is a hole. As the machine moves forward, tomato plants are pulled into the hole. The tomatoes are gathered while the rest of the plants are thrown back onto the fields. Twelve workers sit on top of the machine. They rapidly pick out the bad fruit from the tomatoes. A red stream of ripe tomatoes is being sent into a cart that is pulled alongside the machine. One driver and twelve workers can pick in an hour ten tons of a new kind of tomato. Without the invention, it would take 60 men to do the job.
Not all plants cooperate well with the farming machines. Take lettuce(莴苣)for example, seeds plants in the same field in the same time ripe at different times. The only way to tell a ripe head of lettuce is to look at it and feel it. And now there is a machine even to do that!
There is a special machine to test lettuce. When it moves over one that feels right, it sends a signal back to the picking machine which goes behind. The cutting and picking is done satisfactorily by this unit.

Common sense would tell us that physically active children may be more likely to become active and healthy adults.
In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.
Yet many schools across the country have reduced their physical education programs. Just this week, a study reported that lifeexpectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in fatness, smoking and high blood pressure. They also blame differences in health services around the country.
In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.
Charlene Burgeson , a health expert says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class.
But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.
Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation.The underlined word “expectancy” in Paragraph 3 probably means “ ”

Jeremy Shu-How Lin, who was born in California, 1988, world-famous now，is the first Chinese-American professional basketball player with the New York Knicks of NBA.
It hasn't been an easy road for Lin. After high school, Lin sent his resume(简历) and a DVD of highlights to all the Ivy League schools, and his dream schools Stanford and UCLA. Harvard and Brown were the only schools that guaranteed him a spot on their basketball teams, but Ivy League schools do not offer athletic scholarships.
After graduating from Harvard University, Lin went undrafted in the 2010 NBA Draft . Lin spent his first season with his hometown the Golden State Warriors. He saw limited minutes with the Warriors, but was cheered in arenas(比赛场) around the country, particularly in cities with large Asian communities, as fans came out in crowds to cheer their homegrown star. In late 2011, Lin spent less than two weeks with the Houston Rockets, moving to the New York Knicks at the very end of the year.
He has made several trips to the NBA's Development League, a minor league for players who show promise but need seasoning before they can compete at the highest level. It appears to have paid off. In February 2012, after keying the Knicks victory over New Jersey, Lin was named the starter for the Utah game, a position he appears to have a hold on in the short term, as Baron Davis, who signed in December to play the position, stays on the disabled list. Lin will likely get stronger the more minutes he plays, and even if Davis returns, spelling the older, recovering player could be productive for Lin: a proven good student who can learn a lot from practicing against a veteran.
Without the services of All-Stars Carmelo and Amare, Lin led New York to a 4-0 record last week. He became the first player in NBA history to record at least 20 points and seven assists in each of his first four starts, which generated a global following known as Linsanity. The Associated Press called Lin "the most Surprising story in the NBA". From the passage we can know that Lin ．
| A．enjoyed himself in the Houston Rockets |
| B．used to be a leader in the New York Knicks |
| C．is a proven good student who can learn a lot from other players. |
| D．led New York to success with the help of some All- Stars. |
According to the passage, which statement is true?
| A．Harvard offered Lin an athletic scholarship． |
| B．Harvard and Brown make sure of Lin's position on their basketball teams． |
| C．Stanford and Harvard were Lin's dream schools． |
| D．Lin’s DVD impressed all the Ivy League schools greatly． |
Which of the following can be the main idea of this text?
| A．How the word Linsanity came into being． | B．Introduction to Jeremy Shu-How Lin． |
| C．How Lin becomes successful． | D．Lin and New York Knicks |
Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers.
Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill.
Today many governments have special departments which protect customers and workers．In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products. The main topic of the passage is ___________________________________________.
| A．conditions in the work place | B．the freedom of industries in the past |
| C．changes in industrial production | D．the safety and health of workers and customers |
It can be inferred from the passage that in the past __________________________.
| A．workers often got ill because of the poor working conditions |
| B．companies were free to put out any products they wanted to |
| C．many people were killed by dangerous products |
| D．industries were as careful in management as they are today |
It is implied (暗示) in the passage that ________________________________________.
| A．governments and companies had different opinions about the safety of products |
| B．governments paid little attention to the safety of products |

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?
| A．It can be washed in a washing machine. |
| B．It is much heavier than a leather purse. |
| C．It can download songs from the Internet. |
| D．It is made of clothes conducting electricity. |
According to the passage, these new wearable computers ________________________.
| A．require users to operate on the stomach |
| B．pick up the signals through wires and chip |
| C．are being applied in some different areas now |
| D．are smarter but more expensive than the old ones |
What does the underlined sentence in the last paragraph mean?
| A．These new wearable computers have become fashionable. |
| B．People would like to learn more about these new computers. |
| C．These new wearable computers promise to sell well in the future. |
| D．The idea of these purse-like computers comes from science fiction. |
The purpose of the passage is ________________________________________.
| A．to introduce a new kind of computer | B．to explain the function of computers |
| C．to compare different types of computers | D．to show how high technology affects our life |
