在此请教前辈,Fov里面有句话这样写道:despite the contributions of many great American novelists and playwrights ,shakespeare's plays are still taught in schools more frequently and deeply than any American writer. Correct or incorrect 为什么正确的句子不能是后面直接用that指代plays 改为deeply than that of any American writer 而书上改为deeply than are the works of any American writer
