1.第一种逻辑推理题，题干中没有给出条件，题干中给出suggest,infer,assert,等带有推理意味的词。正确选项一般是根据关键词定位到原文，原文的逆向取非，即双重否定表肯定。原文是A， 正确选项是NOT(NOT A)。 The passage suggest/asserts which of the following about X?
1 ) The passage asserts which of the following about the claim that ALH84001 originated on Mars?
原文：which scientists generally agree originated on Mars
推理方向：NOT(not agree)
正确选项：It’s not a matter of widespread scientific dispute. (not dispute， dispute= not agree)
2)The passage suggests that the fact that ALH has been on earth for 13,000 years has been used by some scientists to support which of the following claims about ALH? 原文：ALH has been on earth for 13,000 years, suggesting to some scientists that its PAH’s might have result from terrestrial contamination.
推理方向：NOT(not result from terrestrial contamination)
正确选项：ALH may not contained PAH’s when it landed on Earth. (即在落到地球之前是没有的，落到地球之前指在火星上= not result from Mars. [result from Mars= not result from terrestrial contamination])
2.第二种逻辑推理题，题干中没有给出条件，但原文中有比较。题干中给出 suggest,infer,assert,等带有推理意味的词。正确选项一般是根据关键词定位到原文，原文的反向比较， 原文是A>B， 正确选项是BA。
1)The passage suggests that socialists within the women’s movement of country X and most bourgeois feminists believed that in Country X
原文： Fninally, socialist feminists and most bourgeois feminists approved of subordinating women's emancipation(A) to what they regarded the more important goal(B)of liberating the entire population of Country A" from political oppression, economic lagging, and social inequity.
推理方向：subordinating= <，即原文A
3.第三种逻辑推理题，题干中给出条件进行比较。题干中给出suggest, ,等带有推理意味的词。题目问，unlike,differ from A, B 怎么样，原文一般在某段讲A 和B 的不同点，但是着重讲A，所以我们要找到A 的特点，对A 的特点进行取非，得出B 的特点。
1)The passage suggests that, unlike the pleiotropic hormones(A), oligosacchairns(B) could be used effectively to. 原文：Unlike O(B)…The five (A)have so many simultaneous effect that they are not very useful in artificially controlling the growth of crops. 推理方向：A 和B 的情况相反。A=非B。问B 怎么样，直接找A 取非，即非A 的情况是B 的情况。
正确选项： artificially control specific aspects of the development of crops. (原文取非)
