问题    Artificial flowers are used for scientific as well as for decorative purpose. They are made from a variety of materials, such as silk and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure.
   The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. The life-size models include 847 species, with remarkably accurate anatomical sections and enlarged flower parts. They are made entirely of glass, often reinforced internally with a wire support.
   The models in colored glass are the work of two artist-naturalists, Leopold Blaschka and his son Rudolph who made them from 1887 through 1936. Their lineage of jewelers and glassmakers traces as far back as the 15th century. The parts were shaped after the glass was softened by heat. Some models were blown. Colored glass was used for many, others were "cold-painted" with a thin wash of colored ground glass or metal oxides and heated until the material fused to the model.
   Since the glass flowers are always in bloom, tropical and temperate species may be studied year-round. The gallery is open during regular museum hours and is included in the general admission fee.
   The museum recently installed several Blaschka glass models from the ware collection which have not been seen at Harvard for decades. You can even see amazingly realistic models of apple and apricot plants illustrating some of the diseases affecting fruits of the Rosaceae family. Other newly installed models illustrate insect pollination, displaying bees enlarged to five inches in size to show pollination techniques.
   The intention of the collection was to have it represent at least one member of each flower family native to the United States. Harvard Professor George Lincoln Goodale, founder of the Botanical Museum, wanted life-like representatives of the plant kingdom for teaching botany. At the time only crude papier-mache or wax models were available. Mrs. Elizabeth C. Ware and her daughter Mary Lee Ware financed the collection and presented it.
   Though it was never completed, it contains species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use. [br] The purpose of the collection was to______.
选项 A、thoroughly study plant structure
B、create a botanical garden where only exotic flowers grow
C、show that glass flowers are more realistic than flowers
D、make a copy of one member of every US flower family
答案 D
解析    近义表述。第六段第一句“The intention of the collection was to have it represent at least one member of each flower family native to the United States”说得非常清楚。【知识拓展】近义表述(paraphrase)也是命题常见的方向。准确定位原文是第一步，第二步则是仔细鉴别。如本题represent对应copy，one member重复表达，every对应each等。
