备战2021年高考英语经典小题考前必刷 19.语篇能力提升之阅读理解.逆转思维提取主旨 【刷技巧】 策略1：文章大意题：定位主旨知文意 文章大意题主要是测试考生对一篇文章的深层理解程度以及在速读中准确定位文章主旨大意的能力。它要求考生在理解全文的基础上能较好地运用概括、判断、归纳、推理等逻辑思维的方法，对文章进行高度概括或总结，属于高层次题。 ▲ 主题句法 解答主旨大意题，找准文章的主题句是关键。下面介绍两种快速找出主题句的方法。 (1)根据文体和写作手法来定位主题句 (2)根据行文标志来定位主题句 转折词 如but，however，in fact，actually等时，其后的内容往往是作者真正想要表达的观点。 总结词 如therefore，thus，in short，conclude 等，其后的内容往往是文章的主题。 疑问句 若首段出现疑问句时，对该问题的回答可能是文章的主题。 ▲高频词法 全文中无明显主题句时，我们可以利用文章中的高频词。任何一篇文章都是围绕某个主题展开的，因此，有的文章中最明显的特点之一是有一个反复出现的中心词，即高频词，也叫做主题词。抓住了它，便容易抓住文章的中心。 ▲逆向思维法 在两个选项看上去都十分正确无法选择时，试着从选项出发，想象一下如果自己以此选项来写文章会有哪些内容，然后把它与文章的内容比较，接近的即为正确选项。 【必刷小题1】　(2020·全国卷Ⅱ阅读B) Some parents will buy any high－tech toy if they think it will help their child，but researchers said puzzles help children with math－related skills. Psychologist Susan Levine，an expert on mathematics development in young children at the University of Chicago，found children who play with puzzles between ages 2 and 4 later develop better spatial skills.Puzzle play was found to be a significant predictor of cognition(认知)after controlling for differences in parents’ income，education and the amount of parent talk，Levine said. The researchers analyzed video recordings of 53 child－parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age. “The children who played with puzzles performed better than those who did not，on tasks that assessed their ability to rotate(旋转)and translate shapes，”Levine said in a statement. The parents were asked to interact with their children as they normally would，and about half of the children in the study played with puzzles at one time.Higher－income parents tended to have children play with puzzles more frequently，and both boys and girls who played with puzzles had better spatial skills.However，boys tended to play with more complex puzzles than girls，and the parents of boys provided more spatial language and were more ac
