核心问题
At last his wife agreed ____ the trip if he allowed her to go also. A. with B. on C. at D. to
《中学英语答疑析难》(高一分册)(吉林教育出版社,p.28)说上面试题的最佳答案是B。但我认为选B(on)是错误的。您说呢?
词典解答
agree on 是指双方或多方“在……方面取得一致意见”或“在……方面达成非正式协议”，因此，用在上面的句子里是不正确的。
agree to 则是指“接受、认可”，常常指并非出于主观愿望的“同意”。因此，用在上面的句子里正好合适。可见，正确的答案应当是 D(to)。
