Theyfoundthathumanactivityiscausingspeciestodieout1,000timesfasterthannormal.他们发现人类活动导致物种灭亡的速度比正常情况快1000倍。(P53)该句中的“1,000timesfasterthan”表达的是倍数。常见的倍数的表示法如下：•

Withoutforests，wewouldhavenoairtobreathe，andwithoutcleanwaterwewouldbeunabletosurvive.没有森林，我们就不能呼吸空气；没有干净的水，我们将无法生存。(P53)该句中without短语引导的是含蓄虚拟条件句，相当于由if引导的虚拟条件句，其用法如下：•

表示与过去事实相反，谓语动词用“wouldhave＋过去分词”；•
