求句子分析：为何有Could He Slowed Down这样的语法现象?
Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age,and how the process of ageing could he slowed down.
为什么这段文章里有：
to be losing和could he slowed down
这两种语法现象的呢?
最后一个是不是错的呢?
谢谢挑战_1,想补充一个心底的疑问:
could后面省略了be,这样被动还成立吗?
中文也很难理解:怎么样的年纪,会他被减缓.
译文是怎样才能延缓老化过程.
我猜会不会打错字,he应该是be呢?

to be losing是进行式不定式,appeared to be losing似乎在失去.
could he slowed down应为could be slowed down
could后面没有省略be,而是将be错打成了he.
how the process of ageing could be slowed down中the process of ageing 是主语,could be slowed down是被动语态的谓语,意思是老化过程被延缓.
全句意思是,Taiju Matsuzawa 教授想弄清,为什么日本北部的本应健康的农民在年纪相对不大时就似乎在失去思考与推理的能力,以及怎样才能延缓老化过程.
