[不定项选择题]共用题干 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 your 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 flow. 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 coat 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.Save your voice for your speech.You
may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you need to
see a doctor.perhaps you can get some advice from a orofessional singer. In the meantime,do not even talk in
a low voice.
What about drinking alcohol to wet your throat?I advise 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. The writer's advice about alcohol before you make a speech is to take one or two drinks so as to give yourself some confidence.
