选项 A、result in
B、result from
C、end in
D、conclude
答案 A
解析 result in导致；result from由于……而发生；end in以……结尾；conclude vt.结束。result in和result from主宾位置刚好相反，例如：His practice results in his success; his success results from his practice. 他的成功在于练习。像这样主宾位置相反的还有be familiar to, be familiar with, 例: We are familiar with this word. 和This word is familiar to us，同义：我们对这个单词很熟悉。其实，这些词组也没有必要死记，要善于分析介词，理解词组含义。result in 中的in表示“结果于一点，集中于一点”；result from 中的from为“来自”；familiar with中的"with"表示“对……方面”；to后面接人，即“对某人而言”，故有familiar to, 可把to sb. 看做单独部分理解。
