请帮我检查一下定语从句!是两个句子合并成定语从句
若我没较大改动就不写原句了.(只用which who whom that whose)
1.This is school in which I stuied five years ago.
2原句The teaching building looks nice.The building was put up last year.
改后The teaching building which was put up last year looks nice.
3原句Tina is a top student.The school gave a medal to her for winning the writing competition.
改后Tina is a top student to whom the school gave a medal for winning the writing competition.
4原句Students like the school news.The radio club broadcasts school news.
改后Students like the school news which the radio club broadcasts.
最好讲一下正确的句子我会加分!
难道真的真的是对的吗
