Question

Peter bought a pair of new trousers.I want to buy_____,too.
A.a new one B.a new pair
C.a new ones

Answer 1

这题应选A
Peter bought a pair of new trousers.I want to buy__a new one___,too.
这里的one代替前面的pair,避免重复、啰嗦.
中文意思也可判断：
“Peter买了一条新裤子,我也想买一条.”
我想你应该不会说“Peter买了一条新裤子,我也想买一条新裤子.”吧?太啰嗦了!
不知回答是否满意,
