3,The lack of ecofriendly habits among the public is thought to be a major
为你分析此句:The lack【主语】 of eco-friendly habits【后置定语一】 among the public【后置定语二】 is thought to be 【谓语(动词短语被动形式)】a major cause【宾语】 of global climate change【后置定语】.最简形式:The lack is thought to be a major cause.这种短缺被认为是主要原因。(至于是什么短缺,什么的主要原因,都是定语修饰成分)希望帮助到你!
