19、) passage?因此这类题的解题方法也分为两种：注意：1文章的段落组织通常采用“总分；分总；总分总”的框架。2内容的展开则常用以下手法：(1)时间顺序：按时间先后顺序说明某一事物的发展情况。(2)空间顺序：按照事物的空间结构顺序进行描写或说明。(3)例证关系：所列举的事物用来论证观点，通常是数据、事例等。(4)对比或类比关系：这类文章通常以对比各事物之间的共同点或差异为主。典例Careers in zoology are extremely varied and unique，and can provide incredible learning and work opportunitie
