他们正在修理的那台车一定很旧.正在课桌边看书的人不可能是我们的历史老师.
还有：那位正在帮助老人的司机是谁?
住在隔壁的那位老板一定很有钱.
他一定是渴了.要不然（or）他不会跑去厨房的.

Answer 1

The car they are repairing must be very old. The person who is reading by the desk could not be our history teacher.
Who is the driver that is helping the old?
The boss living next door must be very rich.
He must be thirsty, or he would not rush to the kitchen.
