I would like it thinned outthis time.
这里的thinned out引导的过去分词短语修饰it对么，然后过去分词有被动的意思，可以如此理解么。
I would like itthinned out this time.
would like 意思是“想要；期望”，是“意欲动词”。 it 是宾语，过去分词 thinned out 作宾补，宾语和宾补是被动关系。
意欲动词 want, like, wish, expect, would like 等可以接复合宾语，过去分词作宾补。
I’d like the jobdone when I come back from the journey. 当我旅游回来时，我想让这工作（被其他人）做完。
The father wantshis daughter taught music in her free time. 爸爸想让女儿在空闲时间学音乐。
上述动词也可以接不定式的被动式，作宾语补足语，即在过去分词前加 to be。比如：
They would like thebook published this year. 他们想要这本书今年出版。
We want thismatter settled immediately. 大家期望这个问题立刻被解决。
