谢谢各位！

When canned using proper methods, food suffers no loss in vitamins or another nutritive elements.

帮我分析下前面一句话的主谓宾　　多谢

On September 6, 1996, civil rights activist Rosa Parks was awarded the Presidential Medal of Freedom, the highest honor the United States government gives to civilian.

后面一句的结构．谢谢了

the highest honor the LACE w:st="on">United StatesLACE> government gives to civilian 后置定语修饰the Presidential Medal of Freedom

When canned是省略的时间状语从句即 When food is canned.

我认为using proper methods是做CANNED的后置定语。

不知道这样是否正确。有请NN讲解！
