问题     On the west side of the island of Manhattan in New York City, tree by tree, leaf by leaf, a 2,500 square foot sector of the Central African Republic’s Dzanga Ndoki Rainforest has been transported to, or recreated at, the American Museum of Natural History’s new hall of biodiversity (生物多样性). When the hall opens this May, visitors will visit one of the world’s biggest and most accurate reproduction of one of nature’s most threatened creations.
    To bring the rainforest to New York, a team of nearly two dozen scientists — the largest collecting expedition the museum has ever organized for an exhibit — spent five weeks in the African rainforest collecting soil, plants, and leaves; recording and documenting species; studying trees; shooting videotape and still photos; and interviewing local people. "This area has been explored very little," says Hoel Cracraft who estimates that the museum will eventually collect 150 to 180 mammals, more than 300 species of birds, hundreds of butterflies, and hundreds of thousands, if not millions, of organisms. The exhibition may even have produced a special prize -scientists suspect they have uncovered several new species.
    To give the forest a sense of realness, the back wall of the exhibit is an enormous video-screen, sounds will come out from hidden speakers, and plans even call for forest smells. Computer controls will vary the effects so that no two walkthroughs (排练) will ever be exactly the same.
    After the team returned to New York, the forest was reproduced with the help of the computer. Computer modeling programs plotted distances and special relationships. Artists studied photos and brought what they saw to life. Plaster (熟石膏), trees were made. Recreated animals began to stand in the rainforest of the hall. Flying creatures will hang from the ceiling. The light in the forest — one of the exhibit’s cleverest re-creations — will seem real. Long tube lights will have the correct color and temperature to produce a natural effect. The plants and animals exhibited throughout the hall exist naturally in a perfect balance — remove one, and the whole is imperfect if not endangered. The exhibit is proof to the hope that the world’s rainforests will never exist solely as a carefully preserved artifact (人工制品).
What is this passage mainly about?
选项 A、The history of the American Museum of Natural History.
B、The reproduction of the rainforest at a New York museum.
C、Visitors’ interest in the rainforest reproduction at a New York museum
D、Saving rainforests in the Central African Republic.
答案B
解析 可定位在第1段第2句：When the hall opens this May，visitors will visit one of theworld’s biggest and most accurate reproduction of one of nature’s most threatened creations．今年五月该大厅对外开放时，参观者将看到世界上受到最严重威胁的自然景观之一的热带雨林的最大、最准确的复制品。选项B把中非共和国的雨林重现于位于纽约的一个博物馆中，就是本文的主旨，故B正确。选项A美国自然历史博物馆的历史，在文中没有提及；选项C参观者对纽约博物馆的雨林重现非常感兴趣，因为展厅还未对公众开放(今年五月)，故表述错误；选项D拯救中非共和国的雨林，过于主观，作者只表明其忧虑而已。
