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。
