问题     When an art museum wants a new exhibit, it buys things in finished form and hangs them on its walls. When a natural history museum wants an exhibit, it often must build it realistically— from a mass of material and evidence brought together by careful research.
    An animal, for example, must first be skinned. Photographs and measurements are used to determine the animal’s structure in a natural position fighting, resting, or feeding. Then muscle forms are built and a plaster shell is made. Finally the skin is pulled over the shell like a wet glove. This completes the animal subject.
    Displaying such things as stone heads, giant trees, and meteorites (陨石，陨星) is basically mechanical. Most other natural history exhibits present more difficult problems. For instance how can a creature be exhibited when it is too small to be seen clearly? In these cases larger-than-life models are built. The American Museum of Natural History has models of fleas (跳蚤), houseflies and a myriad (无数的) of other insects enlarged up to seventy-four times. The models show the stages of the insects’ development and the workings of their bodies.
Models are built larger than life to______.
选项 A、display animals of many different sizes
B、show details that would be hidden in true scale
C、seem more realistic
D、appear more natural
答案B
解析 本题是一道具体细节题。问展品模型制作得比实物大的目的是什么。利用查阅式阅读法，我们可以在文章第三段的第三句话和第四句话中找到相关内容。这两句话指出，比如，当某个生物小到无法看清楚时该怎样展出呢?遇到这种情况，需要制作比实物大的模型。因此，本题的正确答案应是B“以展示那些实物展品中看不到的细节部分”。
