请大家帮分析,it 指的是什么?seemed as though 这几个单词咋理解?she前面有没有少关系词呢?
she had lived in the flat for thirty years and was a veritable magpie at hoarding; and it seemed as though everything she possessed had been tossed out and turned over and over
还想问一个she possessed had been tossed out and turned over and over这句里面哪个是动词呢？怎么区分？possessed 、tossed我就不知道是哪个？

答案

it seemed as though中的it 就是表示一个笼统的情况,并不具体指代句子里的哪个成分,跟how it is going? Take it easy. It's my turn. 这几句话里的it 都是一个用法.
It seemed as though,意思是：仿佛是,好像是,也是一个经常用到的句型,如：It seems as though our plan will be perfect. 似乎我们的计划很完善.
she possessed 是定语从句,修饰everything,这里引导词that省略了,本来是：everything that she possessed
tossed out 和turned over and over是两个并列的谓语动词短语,它们的主语是 everything； 而she possessed 刚才说过了,是定语.
