①倒装与否,取决于句子的内容和说要表达的意思. 倒装的主要目的是为了“突出”和“强调”,因此倒装不是必须的,不是以某个词开头,就一定要倒装的.
② such也好,only也好,在句首并且引起倒装的句子,such或only常伴随着是副词或副词词组,比如：
Such was the wind that we couldn't open the window.
Only later did they realize what had really happened.
③ 上面的头两句, such kind of... such只是形容词,修饰kind；而only she.中的only也是形容词＝unique by virtue of being superior to anything else. 因此即便从语法结构上而言,也不是倒装的一部分.
④ 这句的目的显然是为了强调,因此倒装了；而强调的部分正是（To such an extent ）正序应该是：
(The parents) (love) {their son that they have tried to satisfy every demand of his} (to such an extent).
to 引起的介词词组,描述程度～,to这里的意思：reaching as far as... 中文正是达到某种程度的意思.
