文档介绍：
n to look at our lawn mower. It had broken down the previous summer, and though I promised to repair it, I had never got round to it. I would not hear of the suggestion and said that I would fix it myself.
通过回译和原文的对比，我们可以得出几个结论：
(1) call in比起ask要更为精确，call in somebody to do something是一个固定搭配，意思是“请来某人做某事”;
(2) “机器故障”可以用break down来表达，同时这句话用的是过去完成时，比起过去时更加精确，因为可以强调“割草机坏掉”这件事带来的影响。
(3) “某人没有时间做某事”可以用somebody never gets round to something/doing something来表达。比如“我始终想加个锁，但总是拖着没做”可以说：I keep meaning to put a lock on it, but I never get round to it.
(4) “不愿听(某人的建议、忠告等)”可以用would not hear of something来表达。
这样总结对比下来我们对课文的学问点会有更加深刻的相识。建议有空的同学可以选取新概念英语3当中比较感爱好的课文或段落进行回译练习。在此基础上，我们还可以对课文做做笔头或者口头复述，关于复述的教程可见：怎样对一篇文章进行复述?
此外，须要课文具体分析的同学可以去看一看新概念3教材对应的《自学导读》，上面对课文中出现的长难句、词汇以及课后练习题都有比较具体的分析。
