Researchers documented claims of environmental friendliness made by about 2,000 products and found many too vague or too misleading to meet ISO standards. (05.6 Passage 2)

　　分析主干：Researchers documented claims and found...

　　句子的谓语含and 连接的两个动词。前一个谓语动词documented 接宾语claims，该宾语含两个后置定语：of 引导的介词短语以及过去分词短语made by...。后一个谓语动词是found，用了“find +宾语(many)+补语(too vague or too misleading)”结构。too... to...“太......而不能”，短语不定式to meet...作结果状语。

　　译文：研究者记录下了约2000 种产品所做的环保声明，并发现许多声明要么太模糊，要么会引起误导。结果都不符合ISO 的标准。
