La Gomera is the only place in the world

题型:阅读理解

问题:

La Gomera is the only place in the world which has a whistle (口哨)language. We do not know how and why it began because we do not know the complete 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 a valley can not easily shout to a person on the other side. But he can whistle and be heard. Some of the best whistlers can 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 quite far away from the town, people pass the message 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 one another in the same way when a car breaks down or a cow is lost.

The whistle language is hundreds of years old, and probably it will continue to live on for hundreds of years more. Radio and TV often kill the special ways of speaking in different parts of a country. But on La Gomera you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, people there will be whistling the news and other facts and opinions.

现代家庭电器化越来越高,用电安全是一个十分突出的问题.

(1)下表提供了一组部分人的人体电阻平均值数据:

①表中可看出干燥时电阻大约是潮湿时电阻的________倍.

②在空格中填入对人体加220V电压后的电流值.

(2)洗衣机的外壳是金属的(有许多地方没有油漆),如图(a)表示插头没有接地线,外壳与相线(俗称火线)接触漏电,手触及外壳,试在图中画出电流通过的路线(假设此时M为正,N为负).图(b)表示插头中的接地线,接在洗衣机外壳,此时发生漏电,试在此图中画出电流通过的路线.

(3)电路上有规格为10A熔丝(俗称保险丝),如图(c)用电器R的功率是150W,这时通过熔丝实际电流是多少?一个潮湿的人,手脚触电,为什么熔丝不会断(即熔丝不能救人命)?

(4)图(d)是一种触电保安器,保安器A处用相线和零线双股平行绕制成线圈,然后接到用电器,B处有一个输出线圈,一旦线圈中有电流,经放大后便能推动继电器切断电源.

试说明:①为什么多开灯不会使保安器切断电源;②为什么有人“手地”触电保安器会切断电源;③该保安器能不能为双手“相线零线”触电保安?为什么?

③若人的安全电流是25mA以下,上述哪几项是十分危险的?
