31. Nature not only gave the Middle Atlantic region fine harbors, however endowed it with a first-class system of inland waterways.答案：C
测试点：not only…but also…的用法.
分析：这个结构常常出现在考题中．看到前面出现的not only,就应注意后面是否有but also部分．however应为but also．解题要点：however虽与but also词意相同，但前者是副词，后者为连词。
32. All matter resists any change in their condition of rest or of motion.
答案：B
测试点；代词数的一致.

33. Swans, noted for graceful movements in the water, have been the subject of many poetry, fairy tales, legends, and musical compositions.
答案：D
