While many good and useful claims are being made, it is clear there is a long way to go in ensuring shoppers are adequately informed about the environmental impact of the products they buy. (05.6 Passage 2)
　　分析主干：it is clear that...
　　句首的While 引导让步状语从句，“尽管”......。it is clear......中，it 是形式主语，省略连接词that 的从句there is...才是句子的真正主语。in ensuring...是there be 句型的状语成分，“在确保......方面”。ensuring 后面接的是省略that 的宾语从句。
　　译文：虽然有许多好而有用的声明，但是，很明显，要确保购买者完全知晓所购产品对环境的影响还需要很长的时间。

　　While you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so. (07.6 Passage 2)
　　分析主干：they cannot work...
　　While 引导让步状语从句，“尽管......”。从句中的employ 表示“采用”，不定式to get...作目的状语。work in parallel“并行不悖地起作用”。no matter how 也引导让步状语从句，表示“无论多么......”。
　　译文“尽管要完成定稿这两种思维都不可或缺，可是它们却不能并行着参与写作过程-----无论我们多么认为原本如此。

　　Even people who have a physical disease or handicap (缺陷) may be "well,"in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. (06.12 Passage 2)
　　分析主干:people may be "well"
　　主句的主语people 有一个who 引导的定语从句修饰。if 引导条件状语从句，从句中的they can 是省略形式的定语从句(相当于they can maintain)，修饰health。
　　译文：在这种新的意义上来说，甚至有生理疾患或缺陷的人也是“健康的”，如果他们在面对身体缺陷时尽力去达到可能的最好健康状况的话。
