Question

It's surprising that your brother _______ Russian so quickly－he hasn't lived there very long.

A.picked up B.looked up

C.put up D.made up

Answer

A

【解析】

考查动词词组辨析。句意：你哥哥学俄语学得这么快，真令人吃惊——他在那儿住的时间不长。A项，pick up “捡起；（尤指偶然地、无意地、不费劲地）得到；学会；爬起； 接载”；

B项，look up “向上看；改善；拜访（某人）；查找”；C项，put up “举起；张贴；建造；提高；提供食宿”；D项，make up “组成；补足；弥补；编造；化妆”。根据句意，只有A项符合句意，“picked up Russian” 意为“学会了俄语”。故正确答案为A。
