　　Look after Your Voice
　　Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in you mouth. First gently bite the edges of your tongue with your teeth. Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flows. Or you can imagine that you are slicing a big juicy lemon and sucking the juice.
　　Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks which dry your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.
　　If you sense that you are losing your voice, stop talking completely. In the meantime, do not even talk in a low voice. Save your voice for your health. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If it is' necessary, perhaps you can get some advice from a professional singer.
　　What about drinking alcohol to wet your throat? I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking.
　　Perhaps you want to accept the advice，but you may wonder if you can ever change the habits of a lifetime．Of course you can．Goethe，who lived before indoor skating rinks or swimming pools，said，“We learn to skate in the summer and swim in the winter”．Take this message to heart and give yourself time to develop your new habits．If you are willing to change，you will soon be able to say that you will never forget these techniques because they became a part of your body．

　　保護(hù)嗓音
　　演講者在會(huì)議上經(jīng)常有口干舌燥的經(jīng)歷，這時(shí)他們會(huì)要一杯水喝。其實(shí)你可以調(diào)動(dòng)自己口腔中的唾液來(lái)解決這個(gè)問(wèn)題。首先用牙齒輕輕咬你舌頭的邊緣，或者把整個(gè)舌頭抵在口腔的底部保持不動(dòng)，直到唾液分泌出來(lái)。或者你可以想象你正在把一個(gè)多汁的檸檬切成片并且吮吸檸檬汁。
　　在你講話之前，善待你的嗓音。避免喝牛奶或者乳制品飲料，因?yàn)槟切╋嬈窌?huì)使你的嗓子發(fā)干。一些加糖的熱茶或者是稀釋的果汁可以使你的嗓子保持濕潤(rùn)。
　　當(dāng)你感覺(jué)到你的嗓音正在變沙啞，就應(yīng)該徹底停止講話，連壓低嗓音說(shuō)話都別做。為你的健康考慮省省你的嗓子吧。你也許會(huì)感覺(jué)用紙寫(xiě)筆記很愚蠢，但是你能做的最好的事情就是讓你的嗓子休息。如果有必要的話，也許你可以從職業(yè)歌手那里得到一些保護(hù)嗓子的建議。
　　用喝酒的方法來(lái)濕潤(rùn)嗓子怎么樣?我建議你在說(shuō)話前不要去碰酒精。酒精的問(wèn)題在于第一杯會(huì)給你自信，第二杯會(huì)給你更多的自信。最后你會(huì)感覺(jué)力量無(wú)窮，無(wú)所不能，但是事實(shí)上你的大腦和嘴巴已經(jīng)不能在一起協(xié)調(diào)配合了。所以把你的酒留到講話之后喝吧。
　　也許你想接受這些建議，但是不能肯定你是否能改變多年的習(xí)慣。你當(dāng)然可以做到。生活在室內(nèi)溜冰場(chǎng)和室內(nèi)游泳池時(shí)代之前的歌德曾經(jīng)說(shuō)過(guò)，“我們可以在夏天學(xué)習(xí)溜冰，在冬天學(xué)習(xí)游泳。”把這句話記在心里，給自己一些時(shí)間去培養(yǎng)新的習(xí)慣。如果你愿意改變，你很快就可以說(shuō)，這些技能你永遠(yuǎn)不會(huì)忘記，因?yàn)樗鼈冏兂闪四闵眢w的一部分。
