谁能解释一下这个英文句型的结构如下：you did well to make him agree to be more

you did well to make him agree to be more flexible over terms of the payment
主语：you
系动词：did
表语：well
to make him agree——不定式作原因状语.例：We all rejoiced to hear of your success.听说你们成功了我们很高兴.“make sb.do sth.”使某人做某事
agree to be more flexible——“agree to do sth.”同意做某事
over terms of the payment——在分期付款的问题上.over在这里是介词,表示“关于……”、“在……方面”.
整个句子的意思是：你做得不错,令他同意了放宽分期付款的灵活尺度.
P.S.一楼那种思维方式,我觉得很好,不过这要建立在好语感的基础上.语法并非必需的,我们使用母语时,没人会搬着语法书、套着句型来说话.不过对于我们尚未熟练掌握的东西,多了解一些法则还是比较重要的.Keep learning,probably someday you'll say:"I did well to make my rules more flexible over grammar~"; )

主语 you.同位语did ,make
make sb do sth
sb agree to dobe sth
over the term of the payment 时间状语，在付款期限
整句话的意思是：你使他同意在付款期限问题上采取更灵活的做法很好。

扩展结构

You did well (on sth) to make him agree (what) to be more flexible over terms of the payment.
你做得很好，（在什么事情上呢？）
让他赞同，（赞同什么呢？）
在付款条件上灵活一点。
不知道这个结构要用什么表语状语定语补语来解释。但这样断句是一种思维。...
