关代有一个省略用法是
The boy (who is)standing over there is my brother.
Be 动词后面若是现在或过去分词即可连同关代省略
1. 但在同位语用法中
会看到有些人的解释是
Mr. Lin, a lawyer, lives near my house.
中间的同位语即是省略who is 来的
但a lawyer 并非分词，这样解释是可以的吗?
2. 就算中间是分词，也可以省略吗?
The Company, (which was)established in 1877, has been a leader in its field.
关代如果是非限定用法的话，关代应不能省略吧?
但在用成同位语用法却可以省略变成
The Company, established in 1877, has been a leader in its field.
这两个问题再麻烦大家解答了 谢谢
