例题1：Which of the following can be inferred from paragraph 1 about early sea otters?
A. It is not difficult to imagine what they looked like.
B. There were great numbers of them.
C. They lived in the sea only.
D. They did not leave many fossil remains.
原文1：It should be obvious that cetaceans, whales, porpoises, and dolphins are mammals. They breathe through lungs, not through gills, and give birth to live young. Their streamlined bodies, the absence of hind legs, and the presence of a fluke and blowhole cannot disguise their affinities with land-dwelling mammals. However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses whose limbs are functional both on land and at sea), it is not easy to envision what the first whales looked like.
标题解析：early sea otters是题干关键词，回到原文的语句：However, unlike the cases of sea otters and pinnipeds ...从这里能够看出原文存在的比照，两边是sea otters and pinnipeds与“They”(即 cetaceans, whales, porpoises, and dolphins)，属于第一种推理类型。从内容看“They”的特点是“not easy to envision what the first whales looked like”，所以估测sea otters——“easy to envision what the first whales looked like”，正好是A选项。
例题2：What can be inferred from paragraph 1 about western farmers prior to 1815?
A. They had limited their crop production to wheat, corn, tobacco and cotton.
B. They were able to sell their produce at high prices
C. They had not been successful in raising cattle.
D. They did not operate in a national market economy.
原文2：The story of the westward movement of population in the US is, in the main, the story of the expansion of American agriculture of the development of new areas for the raising of livestock and the cultivation of wheat, corn, tobacco, and cotton. After 1815, improved transportation enabled more and more western farmers to escape a self-sufficient way of life and enter a national market economy during periods when commodity prices were high, the rate of westward migration increased spectacularly.
标题解析：依据题干关键词western farmers prior to 1815定位(要点关注时代)，能够看到关于“After 1815”的信息，这里就能够猜测解题用到时刻比照。只要把1815年之后的内容看懂了，而且在这个内容前面加not即可。文中说到，改进的交通使得越来越多的西部农人摆脱了自给自足的日子，而且进入了国家性的市场经济，那个时候货品的价格许多，所以向西搬迁的速率也大幅增加。所以选项D是正确的。
