the news ()he told us was very exciting,这里面填的是told的宾语呢?还是主语

问题描述:

the news ()he told us was very exciting,这里面填的是told的宾语呢?还是主语
that ,which都可以做主语吗?;
the school ()BIll once studied has becoem famous,becoem famous是什么意思呢?

应该都不可以 become famous 是变得很著名的意思
我觉得应该填where是宾语如果换成正确语序He told us the news that was very exciting.the news 是先行词
