Answer 1

For example, one graphic illustration to which children might readily relate is the estimate that rainforests are being destroyed at a rate equivalent to one thousand football fields every forty minutes – about the duration of a normal classroom period.

* 评注性状语：For example,

* 主句：one graphic illustration is the estimate —— 主系表结构（一个图例/图示说明是这种评价/评估）

* 修饰illustration 的定语从句：to which children might readily relate （儿童可能十分容易地与其联系起来）
—主语：children
—谓语部分：might readily relate to which（需要提前） —— 关系代词which 指代 the graphic illustration，等于relate to the graphic illustration

* 同位语从句：that rainforests are being destroyed at a rate equivalent to one thousand football fields every forty minutes – about the duration of a normal classroom period.
— 关联词：that
— 主语：rainforests（森林）
— 谓语动词（被动）：are being destroyed （被破坏）
— 程度状语：at a rate（以...的速度）
— 形容词短语充当的后置定语（修饰rate）equivalent to one thousand football fields every forty minutes（每四十分相当于一个足球场）
— 说明forty minutes同位语：about the duration of a normal classroom period（大约通常一节课的时间）

直译：例如，一个儿童可能十分容易联系起来的图例，就是森林每四十分——大约通常的一节课时间——以相当于一个足球场的速度遭到破坏的评估。

Answer 2

for example (比如） one graphic illustration (主语 一个图表显示）to which children might readily relate(定语从句修饰illustration孩子们愿意联系到的）is (系词） the estimate (表语 估计）that (引导同位语从句）rainforests are being destroyed at a rate ,后面的是定语修饰rate ,以每四十分钟破坏一千个足球场—— 同位语”相当于我们正常的一节课的时间“
