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)

　　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)

　　主句的主語people 有一個who 引導的定語從句修飾。if 引導條件狀語從句，從句中的they can 是省略形式的定語從句(相當于they can maintain)，修飾health。
　　譯文：在這種新的意義上來說，甚至有生理疾患或缺陷的人也是“健康的”，如果他們在面對身體缺陷時盡力去達到可能的最好健康狀況的話。
