各位先辈们您好...小想请教以下两句
1. Dogs are able to hear more high-pitched sound than human beings
human后面为啥需加beings???
这beings又代表什么意思???
2.Milk went through a lot of hardships to get to where he is today
get to where he is today的to 算是介系词吗??
这里的where是什么意思??
where he is today是什么意思??

1:HUMAN BEINGS=PEOPLE人们,人们的不同讲法WHERE就是哪里啊,TO是介系词,MILK经过了很多困难到达他今天的地位

where 是否等于the position which??where he is today是关代还是名词子句

WHERE= IN WHICH,只是这句话的翻译必需接上下文,不然不好判定是是THE POSITION,不过十之八九应该是啦
