　　请问老师：such和only放句首句子要倒装是吗?

　　Such kind of cognitive transition may change the things they believe. It's ofgreat importance to be able to realise this.改句没有倒装对吗?为什么?

　　Onlyshecandecidewhattodo.这句也不是对吗?为什么?

　　Tosuchanextentdotheparentslovetheirsonthattheyhavetriedtosatisfyeverydemandofhis.z这句中tosuch的to是怎么来的?
