;¥qu«:ßforum.liuxuehome.comqö!ä0Uit’s worth the trip?

;¥qu«:ßforum.liuxuehome.comqö!ä0UQuestions 31-35 Listen to a conversation between two students who’ve met on campus.
;¥qu«:ßforum.liuxuehome.comqö!ä0UHow do you and your housemates like the new co-op? I’m thinking of joining it
;¥qu«:ßforum.liuxuehome.comqö!ä0Umyself.
;¥qu«:ßforum.liuxuehome.comqö!ä0UWe like it quit a bit. We get some very fresh produce and both staples and fair prices.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBut it certainly hasn’t saved us time. The co-op doesn’t carry everything. So we still
;¥qu«:ßforum.liuxuehome.comqö!ä0Uwind up going to the supermarkets too, for cleaning supplies, batteries, that sort of thing.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI wish the co-op sold those items. I’ve been talking about it with some of the other
;¥qu«:ßforum.liuxuehome.comqö!ä0Umembers.
;¥qu«:ßforum.liuxuehome.comqö!ä0UWhat do members have to do? Just pay a membership fee?
;¥qu«:ßforum.liuxuehome.comqö!ä0UYeah. There’s a fee and there’re meetings. But attendance isn’t acquired. But we
;¥qu«:ßforum.liuxuehome.comqö!ä0Udo have to work there for an hour every week, which isn’t too bad. Once you are there
;¥qu«:ßforum.liuxuehome.comqö!ä0Uyou can get your shopping done.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI wouldn’t mind working there sometime. You’ll get to know about the products. But
;¥qu«:ßforum.liuxuehome.comqö!ä0Uis the food free of additives. That will be the main reason I join. I’m a convert from
;¥qu«:ßforum.liuxuehome.comqö!ä0Ujunk food. Until now my diets have been largely chemical additives and pesticides.
;¥qu«:ßforum.liuxuehome.comqö!ä0UWell, a lot of food is pure and pesticide-free. They also have vitamin supplements
;¥qu«:ßforum.liuxuehome.comqö!ä0Uand soy and tofu and that kind of thing. Lots of health food enthusiasts shop there. So
;¥qu«:ßforum.liuxuehome.comqö!ä0Uif any source health oriented, the co-op is.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI’d like to try it just for a month or so. Do they have trial memberships?
;¥qu«:ßforum.liuxuehome.comqö!ä0UThe shortest membership time is one month. Then if you like it, you can join for
;¥qu«:ßforum.liuxuehome.comqö!ä0Ulonger periods. And it becomes cheaper. A six-month membership costs as much as
;¥qu«:ßforum.liuxuehome.comqö!ä0Ufive individual months.
;¥qu«:ßforum.liuxuehome.comqö!ä0USounds pretty easy. Maybe the next time I run into you again it’ll be at the checkout
;¥qu«:ßforum.liuxuehome.comqö!ä0Uline in the co-op.
;¥qu«:ßforum.liuxuehome.comqö!ä0U31. What are the speakers mainly discussing?

;¥qu«:ßforum.liuxuehome.comqö!ä0UQuestions 36-39 Listen to a conversation between two students in the campus cafeteria.
;¥qu«:ßforum.liuxuehome.comqö!ä0UGosh! Fred. Another cup of coffee? That’s your third since lunch.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYeah. Well, I stayed up all night cramming for my history exam. I couldn’t keep my
;¥qu«:ßforum.liuxuehome.comqö!ä0Ueyes open in my last class. I’m having this coffee so I can stay awake this afternoon.
;¥qu«:ßforum.liuxuehome.comqö!ä0UDon’t you know that drinking too much coffee is harmful?
;¥qu«:ßforum.liuxuehome.comqö!ä0UWhat do you mean harmful?
;¥qu«:ßforum.liuxuehome.comqö!ä0UWell, for one thing, it may cause heart disease.
;¥qu«:ßforum.liuxuehome.comqö!ä0UNah. Most of the research about the link between coffee and heart disease is
;¥qu«:ßforum.liuxuehome.comqö!ä0Uinconclusive.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBut coffee has caffeine which is addictive.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou can’t become addicted to caffeine like other drugs.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYes, you can. Don’t you know that people who are deprived of caffeine suffered
;¥qu«:ßforum.liuxuehome.comqö!ä0Uwithdraw symptoms especially headaches.
;¥qu«:ßforum.liuxuehome.comqö!ä0UOne cure for headaches, oddly enough, is caffeine. Haven’t you ever noticed that
;¥qu«:ßforum.liuxuehome.comqö!ä0Umany over-the-counter headache remedies use caffeine as one of their ingredients?
;¥qu«:ßforum.liuxuehome.comqö!ä0UBesides, coffee helps me work faster.
;¥qu«:ßforum.liuxuehome.comqö!ä0UStudies have shown that coffee makes you work faster, but not necessarily better.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou may finish your exam in a shorter period of time but you won’t have fewer errors.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou know, that soda you’re drinking has caffeine in it too.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBut twelve ounces of soda has only half the caffeine of a five ounces cup of coffee.
;¥qu«:ßforum.liuxuehome.comqö!ä0UAnd a cup of tea has less than that.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBut I like the taste of coffee.
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou could drink decaf.
;¥qu«:ßforum.liuxuehome.comqö!ä0UDecaffeinated coffee doesn’t have as much flavor or body as regular coffee.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBesides, I want something that will keep me alert in class.

;¥qu«:ßforum.liuxuehome.comqö!ä0UQuestions 40-43 Listen to part of a lecture in a composition class.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBy the end of the term, I hope you will be convinced as I am that formal writing always
;¥qu«:ßforum.liuxuehome.comqö!ä0Urequires revision. Sometimes it requires a fairly major rewriting of the paper. Some
;¥qu«:ßforum.liuxuehome.comqö!ä0Ustudents have the mistaken idea that revision means simply making corrections in spelling
;¥qu«:ßforum.liuxuehome.comqö!ä0Uand grammar. I call that proofreading. What I expect you to do with your revise is to
;¥qu«:ßforum.liuxuehome.comqö!ä0Uevaluate and improve the overall effectiveness of your paper. But how can you tell if
;¥qu«:ßforum.liuxuehome.comqö!ä0Uyour paper is effective?
;¥qu«:ßforum.liuxuehome.comqö!ä0UWell, for example, start by asking yourself these questions: Is the topic restricted
;¥qu«:ßforum.liuxuehome.comqö!ä0Uenough to be fully discussed within the given length? Are the main ideas clear? Are
;¥qu«:ßforum.liuxuehome.comqö!ä0Uthey supported by specific details and examples? Do they move smoothly from one idea
;¥qu«:ßforum.liuxuehome.comqö!ä0Uto the next?
;¥qu«:ßforum.liuxuehome.comqö!ä0UYou need enough time for a possible major overhaul. That is you may have to make
;¥qu«:ßforum.liuxuehome.comqö!ä0Ua lot of changes before your paper becomes really clear to the reader. So I’ll expect a
;¥qu«:ßforum.liuxuehome.comqö!ä0Upreliminary draft of each paper two weeks before the final due date. That way I can
;¥qu«:ßforum.liuxuehome.comqö!ä0Ucriticize it and get it back in time for you to revise it. Then you can submit a final draft for
;¥qu«:ßforum.liuxuehome.comqö!ä0Ugrading.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThis process may seem like a great deal of trouble at first, but I think you’ll find it
;¥qu«:ßforum.liuxuehome.comqö!ä0Uvaluable. In fact, after you finish this course, I doubt that you well ever turn in a term
;¥qu«:ßforum.liuxuehome.comqö!ä0Upaper without first revising it carefully.
;¥qu«:ßforum.liuxuehome.comqö!ä0U40. What is the purpose of the talk?

;¥qu«:ßforum.liuxuehome.comqö!ä0U43. What effect does the instructor think the class will have on the students?
;¥qu«:ßforum.liuxuehome.comqö!ä0UQuestions 44-46 Listen to part of a radio program about environmental issues.
;¥qu«:ßforum.liuxuehome.comqö!ä0UAre electric cars the way of the future? Automobile manufactures are under pressure
;¥qu«:ßforum.liuxuehome.comqö!ä0Uto develop cars that do not pollute. One powerful motive is a California law requiring that
;¥qu«:ßforum.liuxuehome.comqö!ä0Uby the year 2000 ten percent of new car sells in the state be so called zero-emission
;¥qu«:ßforum.liuxuehome.comqö!ä0Uvehicles. These cars must put no pollutants whatsoever into the atmosphere.
;¥qu«:ßforum.liuxuehome.comqö!ä0UCalifornia is a huge market for the automobile companies, so they are working hard to
;¥qu«:ßforum.liuxuehome.comqö!ä0Umeet these standards. So far the electric car seems to be the best alternative. So the
;¥qu«:ßforum.liuxuehome.comqö!ä0Ubig advantage of electric cars is that they don’t pollute. However they will be in
;¥qu«:ßforum.liuxuehome.comqö!ä0Ucompetition with gas-powered cars and that’s where the weaknesses come out.
;¥qu«:ßforum.liuxuehome.comqö!ä0UThe big problem is that the batteries that power electric cars weigh a lot relative to the
;¥qu«:ßforum.liuxuehome.comqö!ä0Uamount of power they deliver. For instance, in one prototype electric car, the batteries
;¥qu«:ßforum.liuxuehome.comqö!ä0Uweighed 400 kilograms. And they provide enough energy to go 250 kilometers before
;¥qu«:ßforum.liuxuehome.comqö!ä0Urecharging, which takes eight hours. Compare that to a moderately fuel-efficient
;¥qu«:ßforum.liuxuehome.comqö!ä0Uconventional car, it can go 600 to 700 kilometers on a tank of gas and refilling takes just
;¥qu«:ßforum.liuxuehome.comqö!ä0Uminutes. If there are other drains on an electric car’s batteries besides the motor,
;¥qu«:ßforum.liuxuehome.comqö!ä0Uheadlights, air-conditioning or a heater, its already limited range will be significantly
;¥qu«:ßforum.liuxuehome.comqö!ä0Ureduced. So automobile engineers are trying to make more powerful batteries that would
;¥qu«:ßforum.liuxuehome.comqö!ä0Uincrease the cars’ range and make them more attractive to buyers.
;¥qu«:ßforum.liuxuehome.comqö!ä0U44. What is the talk mainly about?

;¥qu«:ßforum.liuxuehome.comqö!ä0UQuestions 47-50 Listen to a talk given at a museum of natural history.
;¥qu«:ßforum.liuxuehome.comqö!ä0UI’d like to welcome you all to the Museum of Natural History. Today’s tour will take us
;¥qu«:ßforum.liuxuehome.comqö!ä0Uthrough our newly renovated dinosaur exhibit where we have the largest collection of
;¥qu«:ßforum.liuxuehome.comqö!ä0Udinosaur fossils anywhere in the world.
;¥qu«:ßforum.liuxuehome.comqö!ä0UBefore we begin the tour, let me mention that there have been some major
;¥qu«:ßforum.liuxuehome.comqö!ä0Umodifications to some of the exhibits over the past three years. Basically these changes
;¥qu«:ßforum.liuxuehome.comqö!ä0Uwere made because of recent changes in the way scientists interpret dinosaur behavior.
;¥qu«:ßforum.liuxuehome.comqö!ä0UFor example, when we get to the first room, you’ll be able to see that the tyrannosaur’s
;¥qu«:ßforum.liuxuehome.comqö!ä0Urex skeleton is no longer standing upright with its tail dragging on the floor. That’s
;¥qu«:ßforum.liuxuehome.comqö!ä0Ubecause paleontologists as they examined the area around its footprints more closely,
;¥qu«:ßforum.liuxuehome.comqö!ä0Urealized they could find no evidence of a heavy dragging tail which would have left behind

;¥qu«:ßforum.liuxuehome.comqö!ä0Upushed forward and its tail is stretched out acting as a counterweight. This new pose
;¥qu«:ßforum.liuxuehome.comqö!ä0Ustresses the relationship between dinosaurs and modern birds and supports the theory
;¥qu«:ßforum.liuxuehome.comqö!ä0Uthat dinosaurs are actually more closely related to birds than to any other existing

;¥qu«:ßforum.liuxuehome.comqö!ä0ULet me also point out that we have changed the way we grouped dinosaurs in our
;¥qu«:ßforum.liuxuehome.comqö!ä0Udisplays. There’s a new school of thought called kledistics where scientists determine
;¥qu«:ßforum.liuxuehome.comqö!ä0Urelationships among the animals according to common physical characteristics. The
;¥qu«:ßforum.liuxuehome.comqö!ä0Uplesiosaurs and the oviraptour for instance, are separated by 148 million years. But

;¥qu«:ßforum.liuxuehome.comqö!ä0Us-shape neck, physical evidence that they are indeed related. So now the exhibition
;¥qu«:ßforum.liuxuehome.comqö!ä0Uhalls are arranged more like a family tree rather than the work-through tine that they used
;¥qu«:ßforum.liuxuehome.comqö!ä0Uto be.
