问题描述：
帮我划分句子成分,指明句子每部分的的作用.
There is a lot of research showing how difficult it is to change happiness based on external factors
答
1.There（表语） is（系动词） a lot of research（主语）there be 引起的倒装句知道吧?这也是这句话的主*分.
2.showing how difficult it is to change happiness based on external factors 作了research的补足语.也可理解为后置定语,但是翻译的时候按照定语翻译会觉得很别扭
3.how difficult it is to change happiness 做了showing的宾语
4.how difficult it is 是感叹句 巨型it is + adj +to do 在这里感叹adj用how
5.based on external factors 做了happiness的定语
6.这句话的翻译：有大量研究表明改变基于外部因素影响下的幸福是多么的困难
7.说的够清楚了吧.嘿嘿我也觉得how difficult it is 是感叹句,to change happiness based on external factors是主观,不像是用来发问的疑问句变来的,,...同时也谢谢abrush0196给我的一些启发,问题结束
