Ⅲ.概要写作
阅读下面短文，根据其内容写一篇60词左右的内容概要。
The guest speaker is a person who is asked to speak at an event.The person is usually not deeply connected with the event. Instead the guest speaker may support the event by sharing knowledge, offering support, or entertaining others.Speakers may give a special speech at the beginning, praising the efforts of community workers, or interesting children or college students in an educational or informative way.In each case, they are defined (给……下定义) by the fact that they will speak or otherwise communicate, and they have been invited to do so.
Even in the smallest events, the guest speaker can be well worth hearing.Coming from outside of the shared opinion of those organizing or attending an event, they often bring something new to it and provide great fodder (草料) for future conversations.Typically, their success depends upon how well they can give a speech.
Clearly the successful guest speaker must be able to make a speech that will be enjoyed and well received by the audience.Some preparation is necessary, and some speakers fully write speeches or memorize them.It helps very much if the guest speaker is given information on how long he or she should speak, and perhaps what topics would be of most interest to the audience.
Almost equal in importance is an introduction to the guest speaker, which should also be well prepared. Especially in large event settings, the person making the introduction should give a little information about the background of the speaker, name some of his or her achievements, and then perhaps suggest why the speaker is present.One of the reasons that these introductions can fail sometimes is that the person doing the introduction doesn't really know who the speaker is, which is why introductions take some preparation.It may be necessary to do a little reading on the history or background of the speaker to make certain that the introduction is flattering (讨人欢喜的) and provides exact information.

[1]Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter­gatherers, small, tightly knit (联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.
[2]Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries，trade, industrialisation, the development of the nation­state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.
[3]At present, the world has about 6,800 languages. The distribution of these languages
is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 languages; the Americas about 1,000; Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number (中位数) of speakers is a mere 6,000, which means that half the world’s languages are spoken by fewer people than that.
[4]Already well over 400 of the total of 6,800 languages are close to extinction (消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining speakers), Chiapaneco in Mexico (150), Lipan Apache in the United States (two or three) or Wadjigu in Australia (one, with a question­mark): none of these seems to have much chance of survival.
