Countries Rush for Upper Hand in Antarctica
A) On a glacier-filled island with fjords(峡湾)and elephant seals, Russia has built Antarctica’s first Orthodox church on a bill overlooking its research base. Less than an hour away by snowmobile. Chinese laborers have updated the Great Wall Station, a vital part of China’s plan to operate five basses on Antarctica, complete with an indoor badminton court and sleeping quarters for 150 people. Not to be outdone, India’s futuristic new Bharathi base, built on stills(桩子)using 134 interlocking shipping containers, resembles a spaceship. Turkey and Iran have announced plans to build bases, too.
B) More than a century has passed since explorers raced to plant their flags at the bottom of the world, and for decades to come this continent is supposed to be protected as a scientific preserve, shielded from intrusions like military activities and mining . But an array of countries are rushing to assert greater influence here, with an eye not just towards the day those protective treaties expire, but also for the strategic and commercial that already exist.
C) The newer players are stepping into what they view as a treasure house of resources. Some of the ventures focus on the Antarctic resources that are already up for grabs, like abundant sea life. South Korea, which operates state-of–the-art bases here, is increasing its fishing of krill(磷虾)，found in abundance in the Southern Ocean, while Russia recently frustrated efforts to create one of the world’s largest ocean sanctuaries here.
D) Some scientists are examining the potential for harvesting icebergs form. Antarctica, which is estimated to have the biggest reserves of fresh water on the planet. Nations are also pressing ahead with space research and satellite projects to expand their global navigation abilities.
E) Building on a Soviet-era foothold, Russia is expanding its monitoring stations for Glonass, its version of the Global Positioning System(GPS). At least three Russian stations are already operating in Antarctica, part of its effort to challenge the dominance of the American GPS, and new stations are planned for sites like the Russian base, in the shadow of the Orthodox Church of the Holy Trinity.
F) Elsewhere in Antarctica, Russian researchers boast of their recent discovery of a freshwater reserve the size of Lake Ontario after drilling through miles of solid ice. “You can see that we’re here to stay,” said Vladimir Cheberdak, 57, chief of the Bellingshausen Station, as he sipped tea under a portrait of Fabian Gottlieb von Bellingshausen, a high-ranking officer in the Imperial Russian Navy who explored the Antarctic coast in 1820.
G) Antarctica’s mineral, oil and gas wealth are a longer-term prize. The treaty banning mining here, shielding coveted(令人垂诞的)reserves of iron ore, coal and chromium, comes up for review in 2048. Researchers recently found kimberlite(金伯利岩) deposits hinting at the existence of diamonds. And while assessments vary widely, geologists estimate that Antarctica holds at least 36 billion barrels of oil and natural gas.
H) Beyond the Antarctic treaties, huge obstacles persist to tapping these resources, like drifting icebergs that could jeopardize offshore platforms. Then there is Antarctic’s remoteness, with some mineral deposits found in windswept locations on a continent that is larger the Europe and where winter temperatures hover around minus 55 degrees Celsius.
I) But advances in technology might make Antarctica a lot more accessible three decades from now. And even before then, scholars warn, the demand for resources in an energy-hungry world could ra

听力原文：W: Hi, Larry, are you waiting to see Professor Gilmore, too?
M: Yah, since I got one of the five highest grades in her class, she asked me if I'd be interested in working as her assistant next semester, I'm here now for my interview.
W: Oh, yes. I know all about that job. I did it two years ago.
M: Really? Did you like it?
W: I think it was the best I've had at school. It paid eight dollars an hour, which was three dollars an hour more than I got working at the school post office the year before.
M: That is a good salary. What did you do?
W: I was in charge of grading all the problem sets that were assigned as homework. I never had trouble doing it, and of course, Prof. Gilmore was always available to help me if I had any questions.
M: I think I'd enjoy doing that sort of work. It would be very good experience for anyone thinking about becoming a teacher.
W: Absolutely. You also learn how to use the computer data base, because the records are kept on it. And building up your computer skills is a good preparation for lots of jobs.
M: The job sounds great, but I'm a little worded about how much time it might take.
W: It's pretty reasonable. It never took me more than five hours a week to do all the grading and then another thirty to forty minutes to record the grades on the computer.
