雅思阅读如何找主题句理清文章框架、概括段落大意是阅读考试中重点考查的技能，而快速抓住段落的主题句，则能起到事半功倍的效果。那么雅思阅读如何找主题句呢?一起来跟我了解下吧。 主题句的位置: 依据对剑 4 到剑 12 文章的分析，段落第一句是主题句的状况多达 65%，约 10%的段落是第二句为主题句，另有约 5%的段落最后一句为主题句。当然也有找不出显然主题句的段落，这部分约占 20%。所以阅读文章时，我们必须要从每段的第一句开始，根据以下原则来确定主题句，从而概括出段落大意。 段落第一句是主题句，通常具有以下特征： 1、首句有概括性的词，如： The sense of vision is developed to different degrees in different species.Baleen species studied at close quarters underwater specifically a grey whale calf in captivity for a year, and free-ranging right whales and humpback whales studied and filmed off Argentina and Hawaii have obviously tracked objects with vision underwater, and they can apparently see moderately well both in water and in air. However, the position of the eyes so restricts the field of vision in baleen whales that they probably do not have stereoscopic vision. 剑 4 Test 1 Passage 2 Paragraph 3 上述例子中，different degrees 就是有概括性的词，整段都围绕着"不同鲸鱼的视觉差异'展开。 由于主题句要统领整个段落，一般无过多的细节，故而句子较短。类似的状况还可以在剑 4 Test 2 Passage 1 Paragraph 1和 剑 5 Test1 Passage 3 Paragraph 2 见到。 2、首句为"人名+宾语从句'的格式，大概率上也可判定为主题句，如： Earlier this year, Sergio Pellis of Lethbridge University, Canada, reported that there is a strong positive link between brain size and playfulness among mammals in general. Comparing measurements for fifteen orders of mammals, he and his team found larger brains (for a given body size) are linked to greater playfulness. The converse was also found to be true. Robert Barton of Durham University believes that, b...
