（教材原句P26）Thatprobablydoesnotseemmuchtoyouorme，butitisarapidincreasewhencomparedtoothernaturalchanges.
这对你我来说很可能是无所谓的，但是跟其他自然变化相比而言，这却是一种快速的增长。
[句式分析]
whencomparedto...是时间状语从句的省略，其完整形式为：
whenitiscomparedto...英语中有时为了避免重复，在不损害句子结构或不引起误解的原则下，往往省去一个或多个句子成分或单词。
在以when，while等连词引导的时间、条件、方式、让步等状语从句中，常常省略相同的主语或作主语的代词it以及be动词，而保留现在分词、过去分词、介词短语、不定式等。
①Whencomparedtooursmallflat，Bill'shouseseemedlikepalace.
和我们的小公寓相比，比尔的房子就像是宫殿。
归纳拓展
状语从句中的省略用法：
②If（Iam）givenanotherchance，Iwilldoitmuchbetter.
要是再得到一次机会，我会把它做得更好。
