Question

请大家帮我分析第2句， 第1、2个that、what在里面起什么做用，各引导什么句？tinted在里面是什么意思？

My cousin, harry, keeps a large curiously-shaped bottle on permanent display in his study. Despite the fact that the bottle is tinted a delicate shade of green, an observant visitor would soon notice that it is filled with what look like a thick, greyish substance

Answer 1

Despite the fact that the bottle is tinted a delicate shade of green,此处的that从句做fact的同位语从句。

形容词 a.
1.(用作定语)(玻璃等)着色的

an observant visitor would soon notice that it is filled with what look like a thick, greyish substance
该句中that...是做动词notice的宾语。
it is filled with what look like a thick, greyish substance
what...是在从句中做介词with的介词宾语。

Answer 2

第一个that 在句中引导主语从句

Answer 3

tinted 是染色的意思，至于句子成分什么的已经还给老师了。。。
