雅思阅读每日一句
对于雅思阅读来说长难句的理解是至关重要的，也是大多数学生为之烦恼的。工作室整理每日一句的初衷就是和帮助大家一起利用碎片时间解析长难句，为翻译题目和理解答案句打好基础。
怎样做每日一句：先对着英文句子尽量自己翻译，然后再看中文释义，如果和自己翻译的差不多一致则后面的可以大致看看或略过，若不一致或翻译不出来则细心看后面的内容详解或评论区留言～
注：所有的长难句都来自剑雅真题

结构拆解
① Although引导的让步状语从句：Although the phenomenon of coral bleaching has been documented since the late 19th century

置于句首，表示"虽然...但是..."
谓语用陈述语气，不是虚拟语气
2. It is...that强调句型
强调"only in recent decades"（直到近几十年）
去掉It is that，还原为：Scientists have only begun... in recent decades
