| 概括大意题解题思路：
1．如果段首句和或段尾句是观点句，可借助段首句和或段尾句的句意判断答案；
2．借助段落中反复出现的核心词/核心结构判断答案；
3．如果段落中有举例的内容，可参考举例内容判断答案；
4．注意段落中出现的观点句（观点句中有时出现这样的一些结构： to sum up (adv.总之, 总而言之); in a word (adv.总之), in conclusion （adv.最后, 总之）等或内容上提到“..研究发现..”， “.某某研究者发现..”），转折句（往往句子中出现“but, however, although, though, nevertheless”等词），因为这些句子可能就是段落的中心句，可参考这些句子句意判断答案。
