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

答案

第三句话不对,因为The school gave a medal to her for winning the writing competition这句修饰的是Tina,我觉得可以这么改：
Tina,who is given the school medal for winning the writing competition ,is a top student.
