we must take all possible measures tending to improve working conditions tending to 如何分析?
答
用来修饰measures，做定语
答
tending to improve working conditions: 短语修饰“possible measures”，意思是“提高工作条件的”
第二个tending to ，意思是“常常”，修饰谓语动词“take”
答
tending to improve working conditions 是现在分词短语作目的状语； to improve working conditions这个大不定式又是 tending的状语
