Question

Six Americans are working on a new highway. But this highway won't have any traffic.It's an "ice highway" to the South Pole.
The team has just finished a second year of work on the 1,020-mile highway. "The road is the greatest single footprint of activity we've seen in the Antarctic (南極洲)," said Alan Hemmings, an Australian environmentalist.
The highway will provide a new way for supplies to be trekked (拉, 搬) across the earth on tractor-pulled sleds (雪橇). This method will use a lot less fuel than an aircraft, the current (當前的) way that scientists and supplies reach the Amundsen-Scott Base, a U.S. research station in the South Pole. The highway will also allow for equipment that is too big for planes to carry to be brought to Antarctica.Even with these benefits, there is one disadvantage—a round trip on the road will be 30 days, compared to a few hours by plane.
Making this 20-foot-wide road isn't easy, and it takes a lot of time. The crew (工作隊) has been working on the road for two summers, when it's warmer and easier to work with the ice. It probably won't be completed until 2006.
Crevasses (裂縫), or cracks, in the land often make the construction difficult. Crevasses are kind of like pot holes that form when surface ice is stretched.This can be very dangerous, especially when the crevasses are hidden under a layer (層) of snow and can't be seen.
"Last year it took us three months to go three miles across a crevasse field, full of dangerous, hidden crevasses," said the project's manager, John Wright. Each year, more crevasses appear and they have to be filled with snow and ice so the road is safe for travel. The road will also be lined with green flags so travelers know where the safe surface is.

      2
   2. B.
      4

   When it is finished, the highway will not be used for ______.
   1. A.
      giving supplies to the research station in the South Pole
   2. B.
      taking scientists to the South Pole
   3. C.
      taking travelers to a tour of Antarctic
   4. D.
      bringing huge equipment to Antarctic
3. 3.
   How many miles can be covered at most each day if you take the ice highway to the South Pole?
   1. A.
      30.
   2. B.
      34.
   3. C.
      68.
   4. D.
      88.
4. 4.
   Which of the following is true according to the passage?
   1. A.
      Other crevasses won’t appear if a crevasse has been filled.
   2. B.
      Many new crevasses will form after a crevasse has been filled.
   3. C.
      Travelers can drive their sleds on the ice highway freely.
   4. D.
      There will be less danger if the crevasses are covered by snow.

這是一篇科普類的短文。本文講述的是關于“美國建造冰上高速公路直達南極”的科普文章。
1.數字計算題。從文章中的The crew has been working on the road for two summers,… It probably won't be completed until 2006. 計算得出。
2.細節(jié)歸納題。文中提到的此條“冰上高速公路”主要用途是…provide a new way for supplies; allow for equipment … to be brought to Antarctica，所以C項不包括在“用途”之內。
3.數字計算題。解這道計算題要抓住文中的兩個數據the 1,020-mile highway ；a round trip on the road will be 30 days，尤其關鍵的是a round trip指“來回”，單程當然為15天，理解了這些數據，計算就容易了。
4.細節(jié)推斷題。從文章的最后兩段可以推斷。
