①商品的价值量由社会必要劳动时间决定,与个别劳动时间没有直接关系。②商品生产者如果提高个别劳动生产率就可以使个别劳动时间低于社会必要劳动时间,给自己的产品提供降价空间,在价格竞争乃至生存竞争中更具优势。所以,个别劳动时间对商品生产者是有意义的。③如果商品生产者竞相提高个别劳动生产率,降低个别劳动时间,从而推动该部门的社会劳动生产率提高,使社会必要劳动时间缩短,单位商品价值量降低,有利于促进了社会生产力的发展、社会的进步和人民生活水平的提高。所以,个别劳动时间对整个社会生产力的发展也是非常有意义的。④所以,

    People can't see you when you're speaking on the phone,but they can hear you.So,the way you speak is especially important.In fact,researchers have calculated that 80% of communication over the phone is through your tone of voice; and only 20% is from the words you use.Here are our top tips on how to speak over the phone.

⒈Facial Expressions

    Your facial expression can influence your voice.For example,if you smile,your voice will sound warm and friendly,just the opposite,if you have an angry look on your face,it can make you sound unpleasant.

⒉Volume

    If you speak too loudly,you could sound angry.And if you speak too softly,it'll be difficult to hear you.So,speak loudly enough to be heard clearly,but not so loud that you're shouting.

⒊Pace

    The pace of your voice is how quickly you speak.And this can show how you feel.For example,an angry person might speak faster than normal.Or a downhearted person might speak very slowly.Try speaking a little more slowly than normal.This will make you sound confident,and it'll make it easier for the other person to understand you.

⒋Gestures

    Gesturing can influence the tone of your voice.When you gesture,you bring more air into the lungs,which can make your voice sound warmer.Gestures are also useful to help you stress the right words or even find the words you need.The best thing about gesturing during a phone call is that no one can see what you're doing,so you can gesture as wildly as you like!

⒌Movement

    If you're feeling nervous,stand up and move around.It will reduce the nervousness in your body and help your voice to sound more confident.

⒍Pauses (停顿)

    Using pauses every now and then can help you to slow down.This will make you sound more confident and in control.Also,if you pause after giving some new information,it'll give the other person time to understand it.At the same time,listen to how the other person uses pauses.They could tell you something about the speaker's feeling.For example,when a speaker is really angry,he might use pauses and says,"I…am…so…angry…"
