意思是：某人怎么会喜欢某事

在一般句式中两者都表示被动语态，但前者表示的是完成时态的被动，前者一般前后有动词的动作发生的先后循序，后者就是被动

例: He had been tought to dance before he entered in kindergarten.

He was tought to dance after he entered in kindergarten.

第一句有动词发生先后循序，been tought 在 entered 之前发生，所以have been 有动词的前后比较，第二句虽有两个动词比较，但是 be tought 在entered之后发生

在独立结构中，两者区别： having been 表示 在后一句子中动词发生的之前发生，being done指同时发生

例：Having been damaged by storm, the house owner had to pay a lot money to repair his house.

Being damaged by strom, the house owner was doing some farming.
