A Guide to the Library's Facilities(设备)

To use or reserve the facilities of the library, follow the procedures given at the circulation desk.

    Group Study Rooms (2F)

Students and teaching staff can use these rooms for group study. Students are advised to use unlocked rooms (3 rooms for 2 people, 2 rooms for 4 people) available for free. When you use locked rooms (2 rooms for 4 people, 1 room for 10 people), you need to go through reservation procedures at the circulation desk. These rooms are available for group discussion.

    Individual Reading Rooms (1-3F)

    There are 4 single rooms available for use by teaching staff and visiting scholars. Each room is equipped with a computer together 1 printer and 6 scanners. Reservation of these rooms is available for a period up to seven days on end.

    Meeting Rooms and Seminar Rooms (1-3F)

    Only teaching staff and graduate students can apply to use these rooms and reserve them one day in advance. The total number of seats is 40. They are available for workshops and small seminars.

    Computer Rooms (4F)

    These rooms are available for classes or seminars and so on. The total number of seats is 88. Only teaching staff can apply to use the computer rooms and reserve them one day in advance.

    See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting “print” on your computer.

    You might find it hard to believe that you could actually “print” an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.

    Instead of ink, the materials the 3D printer uses are mainly plastic, resin(树脂) and certain metals. The thinner each layer is—from a millimetre to less than the width of a hair—the smoother and finer the object will be.

    This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.

    Last year, though, saw a big change in the 3D printing industry—printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost ￡20，000, while now they cost only about ￡1，000, according to the BBC.

    Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of—flutes , bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.

    However, as 3D printing becomes more common, it may bring about certain problems—such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3D printer, who will visit a retail  store again？” an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun?

    Doctors in hospital emergency rooms often see accidental poisonings. A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning.

    In cases like this, seek medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.

    Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts(腹部按压), which you can do by getting directly behind a sitting or standing person. Put your arms around the victim's waist. Close one hand to form a ball. Place it over the upper part of the stomach, below the ribs. Place the other hand on top. Then push forcefully inward and upward. Repeat the abdominal thrusts until the object is expelled from the mouth. For someone who is pregnant or very fat, place your hands a little higher than with normal abdominal thrusts.

    Red Cross experts say taking these steps can save many lives. But they also warn that abdominal thrusts are not for people who have almost drowned. They say use of the method could delay other ways to re-start breathing in the victim. Abdominal thrusts should be used only in cases where a near-drowning victim is choking on an object.

    To learn more about first aid, ask a hospital or organization like a Red Cross or Red Crescent Society for information. There may be training classes offered in your area.

    In the past, people who graduated from college felt proud of their academic achievement and confident that their degree would help them find a good job.

     However, in the past four years the job market has changed dramatically. This year's college graduates are facing one of the worst job markets in years. For example, Ryan Stewart, a graduate of San Jose University, got a degree in religious studies, but no job prospects. He points out that many people already working are getting laid off and don't have jobs, so it's even harder for new college graduates to find jobs.

    Four years ago, the future looked bright for the class of 2013. There were many high-tech job opportunities. Graduates received many job offers, and they were able to get jobs with high salaries and benefits such as insurance and paid vacations. However, “Times have changed and it's a new market,” according to Cheryl Allmen- Vinnidge of the San Jose State Career Center.

    Allmen-Vinniage says students who do find jobs started preparing two years ago. They worked during summer vacations, they have had several internships（实习）, and they have majored in one of the few fields that are still hot, like chemical engineering, accounting, or nursing, where average starting salaries have actually increased over last year. Other popular fields (like information system management, computer science, and political science) have seen big reduction in starting salaries.

    Ryan Stewart (he had hoped to become a teacher) may just end up going back to school. “I'd like to teach college some day and that requires more schooling, which would be great in bad economy.” he said.

    In conclusion, these days, to some students a degree may not be a ticket to instant wealth. For now, they can only hope its value will increase over time.

    Humans' invention of zero was vital for modern mathematics and science, but we're not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.

    Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.

    Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren't just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.

    In further experiments, the researchers showed that bees' understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators（捕食者）and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

For centuries Antarctica has attracted people from around the world. Explorers sought to travel there. Scientists have studied weather, wildlife, and geology there for decades. {#blank#}1{#/blank#} In the last few decades, though, scientists have reported that the ice is melting.

 {#blank#}2{#/blank#} That's a difficult question to answer. The loss of ice in Antarctica has not been linear (直线的). That means it isn't a steady decrease. In fact, the rate of melting can vary greatly from year to year. Still, scientists warn that the continent's ice sheet is shrinking.

{#blank#}3{#/blank#} Climate change is warming the world's oceans and affecting the currents (洋流) of the Earth's oceans. These currents are bringing more warm water to Antarctica than ever recorded.

Today, the planet is warming at a rate that alarms scientists. {#blank#}4{#/blank#} The effects of such a rise could cause major problems. It will increase flooding, especially in areas near shores. A large rise in sea level could even make some regions uninhabitable. This could cause millions around the world to become climate refugees (难民).

Can humans stop Antarctica from melting? Probably not — but experts do believe people can slow the process. How can you help? Pay attention to your carbon footprint. {#blank#}5{#/blank#} Only changes on a large, global scale (范围) can truly make a difference to Antarctica.

A. How quickly is Antarctica melting?

B. Is human activity contributing to the melting of Antarctica's ice?

C. The ice of Antarctica is the result of thousands of years of snow.

D. West Antarctica is the region most affected by these warm waters.

E. Talk with your family about ways to reduce your use of fossil fuels.

F. If this continues, melting ice could lead to a serious rise in sea level.

G. Experts say the melting of Antarctica's ice sheet is caused by rising temperatures.
