The highest beef prices in almost three decades have arrived just before the start of the hot season, causing a great shock to both consumers and restaurant owners—and relief isn't likely anytime soon. A decreasing number of cattle and growing export demand from countries such as China and Japan have caused the average price of fresh beef to climb to $5.28 a pound in February, up almost a quarter from January and the highest price since 1987.

    Everything that's produced is being consumed, said Kevin Good, an analyst at CattleFax, a Colorado-based information group. Prices will likely stay high for a couple of years as cattle producers start to rebuild their cattle among big questions about whether the Southwest and parts of the Midwest will see enough rain to water the grass.

    "I quit buying steaks a while ago when the price went up," said 59-year-old Len Markham, who works at Texas Tech. She says she limits red meat purchases to hamburger, choosing chicken, pork and fish instead.

    Restaurant owners, too, must deal with the high prices. Mark Hutchens, owner of the 50 Yard Line Steakhouse in Lubbock, raised his menu prices for beef items by about 5 percent in November. Since then, the owner of the small eating house has tried to make cuts elsewhere to avoid passing it on to customers. "It really puts more pressure on the small guys," he said of non-chain restaurants. "I just think you have to stay competitive and keep your costs low."

    “White-tablecloth restaurants have adjusted the size of their steaks, making them thinner”, says Jim Robb, director of the Colorado-based Livestock Marketing Information Center. “And fast-food restaurants are cutting costs by reducing the number of menu items and are offering other meat options, including turkey burgers, Robb said. Chain restaurants also try to buy beef as much as they can, which essentially gives them a discount”, Iowa State University assistant economics professor Lee Schulz said.

    The high prices are welcome news for at least one group: ranchers(大农场经营者), especially those in Texas who for years have struggled amid drought（干旱） and high feed prices. But even as ranchers breathe a sigh of relief, some worry lasting high prices will cause consumers to permanently change their buying habits — switching to chicken or pork. Pete Bonds, a 62-year-old Texas rancher and president of the Texas and Southwestern Cattle Raisers Association, said that's a big concern. “But such fears may be unfounded, Robb said. “Three years ago, economists thought consumers would start finding substitutions for beef as the drought spread. We're surprised we haven't seen more of that," he said.

    South Dakota rancher Chuck O'Connor thinks that consumers won't abandon beef for good. "I'm sure some are maybe going to cut back some, but to say that people aren't going to buy it anymore, I don't think that's going to happen," he said, adding, "I hope not."

    Have you grasped the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style.

    Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it and connecting it to things we are already aware .In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures.

    For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message.

    Now scientists say there exist seven basic learning styles.

    Linguistic: These people learn through listening, reading, speaking and writing.

    Logical: These people learn with formula (公式) and principles (原理).

    Visual: These people learn by seeing what they are studying.

    Musical: These people learn well when information is presented through music.

    Kinesthetic: These people learn from movement and physical activities.

    Intrapersonal: These people learn best by linking new information directly with their own experiences.

    Interpersonal: These people learn well by working with others.

    Therefore, if you know what learning style is your strength, you can balance your weakness, and get a more successful learning experience.

    Homesick is a compound word made up of HOME and SICK. You know what each word means on its own, of course. But think about what the words mean when they are used together. Homesick means SICK FOR HOME.

    Now think for a minute about SEASICK. If you change the word home in the definition(释义)to the word sea, would the definition fit SEASICK? Seasick means SICK BY THE MOVEMENT ON THE SEA. When you are homesick, the only place you want to be is at home. When you are seasick, the last place you want to be is at sea.

    Have you ever heard of a person being heartsick? Heartsick doesn't mean that something is wrong with a person's heart, people are heartsick when they are hurt deep inside and when they feel as if their hearts are broken.

    But, on the other hand, we have such compound words as handshake, handstand, and handbag. Perhaps you may write definitions for them.

Pride and Prejudice for the Modern Woman

    Let us imagine how Pride and Prejudice, Jane Austen's most famous work, might be updated, 200 years on. Austen's popularity is rooted in her intelligence. But today she would certainly have had a very different life, as would her characters(角色). Here's my own suggestion…

    It is a truth finally and universally acknowledged that a single woman with brains deserves to have equal opportunities to men, however disadvantaged she may feel by sexism.

    "My dear husband," said his hopeful wife one day," have you heard that the local store, standing empty for so long, is taken over by a bright young businesswoman?"

    Her dull and indifferent (漠不关心的) husband replied that he had not. "But it is, it is," she replied excitedly. Mr. Dull-Husband made no reply.

    "Don't you want to know her plans?" she cried with some impatience.

    "Well, clearly you think it matters to your silly little head, so I'd better listen."

    "Well, my dear, the rumour (传言) is that she has already set up a string of successful businesses in northern England, though how a woman can know anything about that is beyond me". She will move in herself next month." "What is her name?" "Bingley."

    "Is she married or single?"

    "What a question! And none of your business. But her coming will be a fine thing for our five boys." "How so? How can it possibly affect them?"

    "My dear love; those lazy boys need something to wake them up. There are bound to be jobs going."

    "Is that her point in settling here? Surely as a woman she has simply taken a fancy to the place."

    "Nonsense, my love, how little you've noticed the world has changed. She's got a first-rate degree and some sort of business qualification, I'm told. She surely needs one of our boys! Perhaps you might give her a call."

    "Me? No. Perhaps you can take an interest. You still have your looks, after all. She may even offer you a job." "Oh, that's not likely. These new chances belong to the younger generation. But now you mention it, I think I'll go along all the same."

    And Mrs Bennet went along. That was 10 years ago. She is now managing director of a FTSE-listed company.

    It would remain the case, of course, that Mrs Bennet would be one of very few women on the company board, that her salary would be lower than her male colleagues, her bonus of a more "female" dimension(方面) and her lifespan (年限) among the city's business leaders shorter than theirs. Still, she'd no doubt have enjoyed Davos(达沃斯经济论坛)—and might even have hobnobbed (攀谈) with influential figures.

    One summer I was driving from my home town of Tahoe City, Calif., to New Orleans. In the middle of the desert, I came upon a young man standing by the roadside. He had his thumb out and held a gas can in his other hand. I drove right by him. There was a time in the country when you'd be considered a jerk if you passed by somebody in need. Now you are a fool for helping. With gangs, drug addicts, murderers, rapists, thieves lurking everywhere, "I don't want to get involved" has become a national motto.

    Several states later I was still thinking about the hitch­hiker. Leaving him standing in the desert did not bother me so much. What bothered me was how easily I had reached the decision. I never even lifted my foot off the accelerator.

    Does anyone stop any more? I wondered. I recalled Blanche DuBois's famous line: "I have always depended on the kindness of strangers". Could anyone rely on the kindness of strangers these days? One way to test this would be for a person to journey from coast to coast without any money, relying solely on the good will of his fellow Americans. What kind of Americans would he find? Who would feed him, shelter him, carry him down the road?

    The idea intrigued me.

    The week I turned 37, I realized that I had never taken a gamble in my life. So I decided to travel from the Pacific to the Atlantic without a penny. It would be a cashless journey through the land of the almighty dollar. I would only accept offers of rides, food and a place to rest my head. My final destination would be Cape Fear in North Carolina, a symbol of all the fears I'd have to conquer during the trip.

    I rose early on September 6, 1994, and headed for the Golden Gate Bridge with a 50­pound pack on my back and a sign displaying my destination to passing vehicles: "America".

    For six weeks I hitched 82 rides and covered 4,223 miles across 14 states. As I traveled, folks were always warning me about someplace else. In Montana they told me to watch out for the cowboys in Wyoming; in Nebraska they said people would not be as nice as in Iowa. Yet I was treated with kindness everywhere I went. I was amazed by people's readiness to help a stranger, even when it seemed to run contrary to their own best interests.

    When you think of batteries, you'll likely think about them powering up remote controls, cellphones, flashlights and toys. But some people carry a battery around in their body to power a pacemaker (起搏器). It isn't really pleasant and easy to carry batteries because they need to be replaced so often and they can leak poisonous chemicals. A battery-powered pacemaker may become a thing of the past, thanks to a new technology developed by UCLA researchers: A biological super capacitor (超级电容器) , which is thinner than several hairs.

    Teams of researchers at UCLA and the University of Connecticut published a paper in a journal explaining their new invention. The super capacitor is made from a carbon material, and coated with human-like proteins that act as electrodes (电极). But what makes the device different is that it is powered by an energy harvester that changes body heat and movement in the blood into energy.

    Those traditional pacemakers are six to eight millimeters(毫米) thick. They are much bigger. The new super capacitor, which, due to its lack of battery, is only one micrometer(微米) thick. This "little" feature could benefit the new pacemaker's energy efficiency, researchers stated. Also, unlike other batteries used in medical treatments, the super capacitor can bend and twist in the body without suffering damage.

    Though they've not been widely used in the medical world, super capacitors have the ability to serve as a safer and more efficient medical device than the traditional battery-operated devices, the researchers believe.

    "In order to be effective, battery free pacemakers must have super capacitors that can get, store and transport energy. However, commercial super capacitors are too slow to make them work", said Maher El-Kady, a UCLA researcher and co-author of the study. “Our research focused on the custom-designed super capacitor to capture energy effectively, and finding a way to make it exist together successfully with the human body."
