64._____ in thought,Mr.Smith almost ran into the car in front of him.
A) Losing B) Lost C) Having lost D) To lose
B)句意：因为在想事情,史密斯先生几乎自己撞上迎面驶来的车子.这是典型的复合式考点选择题.
考点一：lose sb.in sth.使某人陷入...中,这里的lose是vt/及物动词,该词组也常用被动态sb.is lost in sth..
考点二：“独立主格”掌握情况的考察.“ Mr.Smith almost ran into the car in front of him”主语是Mr.Smith,如果把上面的句子拆成两句,应该是“1)Mr.Smith was lost in thought.2)Mr.Smith almost ran into the car in front of him.”
1)+2)=(Because he is)Lost in thought,Mr.Smith almost ran into the car in front of him.去连词,主语,be谓.
然后逐一排除其余选项
A）考虑逻辑关系,应是被动形式Lost
C）应是被动形式Lost,即使一定要表现完成时,也应当加上时间状语e.g.：Having been lost in thought for a long time/ for several minutes
D）同A）理
