【正文】 the plete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley can not easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.4. If a person on Comera island is ill, .

In many instances, we produce idioms which are all understandable by borrowing examples from animal munication.For example, we know that a frightened cat will arch（拱型）. From this startingpoint we might hear the expression. “He gets my back up!” meaning “He makes me angry.”In the same manner, we know that many animals, if challenged（挑戰(zhàn)）by attackers, will not turn and run away because this will encourage the attackers to attack them more forcefully. Instead, they will move backwards slowly to get out of harm’s way, always facing their attacker. We call this action “backing off” and it can be used as well with humans as with animals.In the case of humans, however, the backoff may not be physical but oral, as in using a kinder tone of voice and gentle words instead of fighting against the attackers.8.

A. grammar B. idioms C. expression D. municationDFor as long as humans have lived on the earth, they have made use of various forms of munication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a spoken language problem, munication can be carried out through sign language, in which gestures stand for letters, words, and ideas. Tourists and people unable to hear or speak have often had to turn to this form of expression. When gestures describe words or ideas, they can often be used internationally. When used for spelling words however, where each gesture stands for a single letter, people must share the same written language.Body language sends ideas or thoughts by certain actions, either meaningfully or not. A wink can be a way of showing that the person is only joking. A nod means agreement, while shaking the head indicates disagreement.Other forms of language can be found in Braille (a reading system of raised dots read with the fingertips used by the blind), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide and warn people. While language is the most mon form of munication, other systems and techniques also express human thoughts and feelings.12.
