问题补充:
The two brothers look so much alike that it is difficult to.
A. tell them from
B. tell from them
C. tell them apart
D. tell apart them
答案:
A. tell them from
B. tell from them
(答案→)C. tell them apart
D. tell apart them
解析:把两者区别开来,应用tell apart;把一者同另外一者区别开来用tell from,排除A、B两项。在由“动词+副词”构成的词组中,代词要放在动词之后,副词之前。
