分析：该句意思是说“动物没有长期记忆。”关键词是：long-term memory.在第五段中我们发现谈到了长期记忆和短期记忆。但没有讲到动物是否具有长期记忆，所以，判断为：Not mentioned。
21. Long—term memory is more important than short-term memory．
A. Right B. Wrong C. Not mentioned
分析：本题意思是：长期记忆比短期记忆更重要。和上一题一样，我们在第五段中没有看到相关的信息，所以应属“没提到”类型。因此选择C。
22. Generally（一般说来） we remember only（仅仅） a few （几个、一些）facts about the past（过去）．
A. Right B. Wrong C. Not mentioned
分析：该题是最后一题，我们通常情况下应从最后一段寻找线索：
Psychologists（心理学家） tell us that we only remember a few facts about our past（和题目的内容表述一致！），and that we invent （虚构、编造）the rest．两段内容完全一致，所以判断是A。
接下来，要向大家介绍概括大意与完成句子题：通常情况，文章难度低于阅读理解部分的文章难度. 文章结构通常为说明文或论述文. 该部分题通常是从书外出题.对于该部分试题，首先在做题的时候应该明确，本题分为两个部分，考查的重点也各有不同。概括大意考查总结文章主要意思的能力，做题方法比较单一，对大家难度不大；完成句子考查的是文章细节，具体的考点有：1、利用回文定位快速查找答案的能力；2、利用paraphrase，根据同义替换和句意转换，确定与文章细节意思一致的表述。
特殊句子结构： however, but, on the other hand, nevertheless, although, though, even if(表示转折或让步语意)；therefore, thus, accordingly, so, consequently, hence, as a result (表示结果)；in general, generally, in a word, to sum up, in conclusion(表示总结概括)
段落标题还往往有一个特点，即：选出的小标题里一般应该包含了指定段中的某个出现频率较高的某个词或主题句中的中心词或以其的另一种词性出现，如：原文中的某个核心动词在标题句中是以其名词的形式出现的，这一线索也是帮助我们正确和快速解题的关键。
例题分析： Ways to Reduce Exposure to Air Pollution
1 A report published recently brings bad news about air pollution．It suggests that it could be as damaging to our health as exposure to the radiation from the 1986 Ukraine nuclear power plant disaster．The report was published by the UK’S Royal Commission on Environmental Pollution．But what can city people do to reduce exposure to air pollution? Quite a lot，it turns out．
2 Avoid walking in busy streets．Choose side streets and parks instead．Pollution levels can fall a considerable amount just by moving a few meters away from the main pollution source—exhaust furies(废气)．Also don’t walk behind smokers．Walk on the windward(顶风的)side of the street where exposure of pollutants(污染物)can be 50 percent less than on the downwind(顺风的)side．
3 Sifting on the driver’S side of a bus can increase your exposure by 1 0 percent，compared with sitting on the side realest the pavement．Sifting upstairs on a double—decked(双层电车)can reduce exposure．It is difficult to say whether traveling on an underground train is better or worse than taking the bus．Air pollution on underground trains tends to be less toxic(有毒的)than that at street level，because underground pollution is mostly made up of tiny iron particles(粒子)thrown up by wheels hitting the rails，while diesel(柴油机)and petrol fumes have a mixture of pollutants．
4 When you are crossing a road，stand well back from the curb(路缘)while you wait for the light to change。Every meter really does count when you are close to traffic．As the traffic begins to move，fumes can be reduced in just a few seconds。So holding your breath for just a momen
