    找人家?guī)兔σ灾链饝?yīng)幫人家忙都是一個(gè)很大的學(xué)問，如果有人來告訴你說："Would you do me a favor?"‘你可以幫我一個(gè)忙嗎？’其實(shí)你心里非常愿意幫助他，但等了幾秒才平平淡淡說一句"Okay"，相信那個(gè)人以后不管發(fā)生再大的困難，都不好意思來找你了。所以如果有人找你幫忙，而你又非常愿意幫忙的話，你一定要用非常樂意的語氣說："Certainly, I'd be happy to." ‘當(dāng)然啦，我會(huì)非常樂意?！阋部梢杂帽容^隨意的方法回答："Sure, that’s my pleasure." ‘當(dāng)然，能夠幫你的忙，這是我的榮幸?！蛘呤?No problem, any time." ‘沒有問題，隨時(shí)奉陪?！韵嘈胚@個(gè)朋友一定會(huì)非常高興。就算你真的沒辦法幫人家時(shí)，你也應(yīng)該跟人家解釋一下："I wish I could, but sorry I can't." ‘我真希望我能幫你，只可惜我真辦不到?！?BR>    對(duì)話來源：考試大
    A：Hey, Ricci. What's the matter? What can I do for you?
    B：Oh, my mobile phone is out of order. Would you come with me to buy a new one? I need your advice.
    A：Certainly. I'd be happy to. But we don't have to go to the store. Here you are.
    甲：嘻，麗琪。發(fā)生了什么事? 我有什么可以為你效勞?
    乙：噢，我的手機(jī)壞了。你可以陪我去買一部新的嗎? 我需要你的意見。
    甲：當(dāng)然可以，我樂意之至。但我們不必去商店買，這里就有。
    某甲的行動(dòng)電話壞了，問某乙可不可以陪他去買新的。某乙說：Sure. But we don't have to go to the store.（當(dāng)然可以，但不必去商店買。）這句話值得談?wù)?。答允人家的要求，語氣要熱誠。你可以說Of course/Certainly/Sure（當(dāng)然可以）、I'd be glad (happy) to./I'd love to./Willingly.（我十分樂意）、Will do.（可以）等，例如："Could you post this letter for me?" "Will do."（ ‘可以替我寄這封信嗎？’ ‘可以?！?BR>    拒絕人家的要求，客氣的說法是I'm sorry/afraid I can't.、I regret that I can't.（對(duì)不起，我沒法幫忙。）、I'd like to say yes, but that's impossible.（我很想答應(yīng)，只是愛莫能助。）、I'd rather not if you don't mind.（我不大樂意，希望你不要介意。）不客氣的說法有Save it./Save your breath.（別浪費(fèi)唇舌了。）、I'll be damned first.（我是王八才答應(yīng)你。）、Over my dead body.（我死了再說吧。）、Nothing doing.（不行），例如："Could you lend me ten cents?" "Nothing doing!"（ ‘借一毛錢給我行不行？’ ‘不行！’）
    現(xiàn)在說We don't have to go.一語，Have to和must往往通用，解作‘必須’，例如：You have to/must go there.（你必須去那里。）但是must not和don't have to意思卻完全不同；must not是 ‘不得’，do not have to則是 ‘不必’，例如：You must not tell him.（你不得告訴他。）、You don't have to tell him.（你不必告訴他
