which/who
【问】 (1)Thomas Alva Edison 
man 
invented the light bulb. (TOEFL，81)
(2) Mrs Swanson， a member of the social committee for the 
years， 
the 
woman 
has a car. (TOEFL，78. 2)
上面的两题均要求将which改为who，由此判断，关系代词which是不能指人的名词的。但是下列句子如何解释?
His brother has become an engineer，which he wanted to be.
【答】 对于初学者应当指出which一般是不能用来指人的。用which来指人是有条件的，见which7。
请做下面英语试题：
The Tartar chief 
a thousand men， all of 
must obey his orders 
bothwar and 
(TOEFL，80·2)
