以下是我自学listen to this 2第三课里面的几句话，虽然根据上下文我能猜到大概的意思，但是我不知道准确的翻译。请问我的理解是否正确？the machine was obviously defective when I bought it 意思是这个机器买的时候就有瑕疵？还是买的时候就损坏了？ I mean, surely you're going to make good on this cassette player 你们一定会帮我修的？But surely you won't hold me to ten days on this. 你们不会跟我计较这10天的吧？
the machine was obviously defective when I bought it
我买它时，本机是明显的缺陷。make good on是指兑现（诺言）补偿之类的。
make good on是指卖方应该兑现免费修理录音机的承诺
look for :寻找 see 与hear 表示一种感官，没有意识的去看和听 listen，有意识的听，for表目的 listen for main point：听别人讲话时抓住要点．
