ae接受灯光:关于英语倒装句的问题

部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。
全部倒装是只将句子中的谓语动词全部置于主语之前。
play也是一个谓语吧

一、英语句子的主语通常位于谓语动词之前，这种语序被称为正常语序。但有时出于修辞或某种特殊的语法结构的需要，需要将谓语动词放在主语之前，这种语序则叫倒装语序。按倒装的形式，倒装可分为类，一是部分倒装，二是完全倒装。前者指主语和助动词倒置，后者指主语和谓语完全倒置。
二、部分倒装的用例
使用部分倒装的情形比较复杂，如在正式文体中，never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere 等含有否定意义的副词若位于句首，则其后要用部分倒装：
I shall never forgive him. =Never shall I forgive him. 我永远不会宽恕他。
He seldom goes out for dinner.=Seldom does he go out for dinner. 他很少出去吃饭。
She hardly has time to listen to music. =Hardly does she have time to listen to music. 她几乎没时间听音乐。
He little realizes how important this meeting is. =Little does he realize how important this meeting is. 他不甚明白这个会议的重要性。
We had no sooner reached the airport than the plane took off. =No sooner had we reached the airport than the plane took off. 我们刚到机场,飞机就起飞了。

三、完全倒装的用例
使用部分倒装的情形也有几种，如表示地点的here和 there位于句首时，其后用完全倒装形式。这类倒装句的谓语通常是动词be和come, go等表示移动或动态的不及物动词：
Here’s Tom. 汤姆在这里。
There’s Jim. 吉姆在那儿。
Here comes the bus. 公共汽车来了。
There goes the bell. 铃响了。
另外，地点副词away, down, in, off, out, over, round, up 等位于句首时，其后用完全倒装语序。这类倒装句的谓语通常表示动态的不及物动词：
Away went the runners. 赛跑选手们跑远了。
Round and round flew the plane. 飞机盘旋着。
The door opened and in came Mr Smith. 门开了，史密斯先生进了来。
Down came the rain and up went the umbrellas. 下雨了，伞都撑起来了。

四、关于你提到的例子
你的例子：So busy is he that he has no time to play with his daughter. 的确是一种部分倒装。因为，英语的部分倒装涉及这样一种情形：当so…that句式中的“so+形容词或副词”位于句首时，其后用部分倒装。如：
So cold was the weather that we had to stay at home. 天气太冷，我们只好呆在家里。(was 与 the weather 倒装)
So sudden was the attack that we had no time to escape. 袭击来得非常突然，我们来不及逃跑。(was 与 the attack 倒装)
So fast does light travel that we can hardly imagine its speed. 光速很快，我们几乎没法想像它的速度。(does light travel 为 light travel 之倒装)

因为So在这里修饰的是busy阿
