Inference questions 推理题 

 

　　推理题的象征是在题干中呈现infer/imply/suggest/indicate/most likely 这样的词汇，它和细节题归于同源标题，都需求定位而且依据文中信息来挑选答案。与细节题不一样的是，推理题在找到原文中定位点之后调查的是学生关于文中信息的总结归纳，或许反向推理的才能。咱们来看一道例题，

 

　　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 fluke3 and blowhole4 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. Extinct but, already fully marine cetaceans are known from the fossil record. How was the gap between a walking mammal and a swimming whale bridged? Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans.

 

　　Which of the following can be inferred from paragraph 1 about early sea otters?

 

　　○ It is not difficult to imagine what they looked like

 

　　○ There were great numbers of them.

 

　　○ They lived in the sea only.

 

　　○ They did not leave many fossil remains.

 

　　首要咱们来对标题的命题规模进行定位，题干的blowhole能够作为定位词汇，定位到原文的第四句话：“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.” 在这句话里告知了“unlike the casess of sea otters”，即与sea otters 不一样的是，whales 的陈说是：it is not easy to envision what the first whales looked like. 即，不容易看出榜首头鲸长啥姿态。而sea ottter 是和鲸鱼相反，所以挑选A选项，即不难看出榜首头sea otter 长啥姿态。所以实际上，这种标题尽管叫做推理题，可是并不需求同学们在做题的时分推的过远，根本调查的仍是对原文信息归纳和总结的才能。
