1、分词的完成式表示一个更早的过去动作,sb + be lost in thought,是表示心理状态的,还处在沉思状态的同时,就稀里糊涂地钻进前面的车里了（上错了车,因为走神了）.
即使要表达“先处于沉思,后导致进错车”也不能用B.
只可说：Having been lost in...
2.1中的解释正好适用2句的情形了,因为先未收到,后才决定,这两件事不时同时发生,有明显的先、后.故用D.
3.这句如不省略,完整形式是：
When it is completed,the museum will be open...
就是俗称的“主将、从现”规则.
此处的completed,adj.不是单纯的过去分词,应当是含有“完成的/完工的”adj.侧重状态而非动作.故省略...it is...
虽然表示将来,但是个类似于条件句,将来的条件依然用一般现在时.

1.C. Lost 为正确选项
be lost in sth （沉醉于。。。，陷入。。。。）的简略句，做原因状语。简略时只保留过去分词。
2.D.Not having received 为正确选项
这里是强调没有收到membership card，故用了分词的完成时态。做原因状语。
3. A.completed 为正确选项。
when it is compl...

2.D.Not having received 为正确选项
这里是强调没有收到membership card，故用了分词的完成时态。做原因状语。
3. A.completed 为正确选项。
when it is completed 的简略句，做时间状语。简略时只保留过去分词。
这是一组分词做状语的练习题。

收起

1.B时态不对。having lost是现在完成时 ran是过去式
2。是没收到卡片才决定打电话，发生在decided前用完成时
3。when the museum is completed ,从句与主句主语与谓语都相同时，从句主谓可以省略
