(1) 题是:
Astronauts who experience weithtlessness frequently get motion sickness. The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies are not moving. The astronauts' experience is best explained by the hypothesis that conflicting information received by the brain about the body's motion causes motion sickness.
问加强.
我选C----Some automobile passengers whose inner ears indicate that they are moving and who have a clear view of the objects they are passing get motion sickness.因为此项很好的体现了原题中的'conflicting information'的意思.
但答案是A---During rough voyages ship passengers in cabins providing a view of the water are less likely to get motion sickness than are passengers in cabins providing no view.我觉得它反倒削弱了命题.
(2)题是:
Some good cooks are gourmet cooks who pride themselves on always using extravagantly rich ingredients in elaborate recipes. Some good cooks can be characterized as fast-food cooks. They may used rich ingredients as long as the recipes are easy to follow and take little time. Other good cooks are health food enthusiasts, who are concerned primarily with the nutritional value of food. But even though not all good cooks are big eaters, they all enjoy preparing and serving food.
问归纳.
我选B----Everyone who enjoys preparing and serving food is a good cook.我认为此项太绝对了.
但答案为D---There are fewer good cooks who enjoy serving and preparing food than there are good cooks who are big eaters.这项我觉得确实也应选.但怎么排除B了?
(3)题是:
Baking for winter holidays is a tradition that may have a sound medical basis. In midwinter, when days are short, many people suffer from a specific type of seasonal depression caused by lack of sunlight. Carbohydrates, both sugars and starches, boost the brain's levels of serotonin, a neurotransmitter that improves the mood. In this respect, carbohydrates act on the brain in the same way as some antidepressants. Thus, eating holiday cookies may provide an effective form of self-prescibed medication.
问归纳.
我选B---Lack of sunlight lowers the level of serotonin in the brain.
但答案为D---Sone antidepressants act by changing the brain's level of serotonin.
D我倒是想通了, 但B为什么错了?
第三题:同题干你可以推出lack of sunlight caused seasonal depression ,但seasonal depression 和serotonin并没有什么必然的联系.也不能进而推出Lack of sunlight lowers the level of serotonin in the brain,我记得老师讲课的时候说过,GMAT的逻辑推理一般都是一层推理,不能再进行第二层或更深层次的推理,你好象就犯了这个错误.
No matter what happens ,tomorrow is another day !
I am hope!:)
