[01:40.95]The Different Uses of Metals The Reaction of Metals

[01:49.66]The Reaction of Metals with Oxygen

[01:55.74]Passage A It is hard to think of a world without metals.

[02:01.75]Different metals have different uses, for example, steel is used in cars,

[02:08.94]and iron is used in electrical equipment. When we use metals,

[02:14.81]it is important to know how they react with different substances,

[02:19.43]for example, water and oxygen.

[02:23.37]The reaction of metals with these substances can be put in order.

[02:29.50]Here is a table with the metals that react most at the top,

[02:34.36]and the metals that react least at the bottom.

[02:41.04]4.Read the passage and fill in the table.

[02:47.56]Passage B A Simple Scientific Experiment

[02:52.88]Below is a description of a simple scientific experiment.

[02:58.04]It shows us how iron reacts with air and with water.

[03:03.50]Aim:To find out if iron rusts (a) in dry air;

[03:09.93](b) in water that has no air in it (air-free water);

[03:16.67](c) in ordinary water.

[03:20.45]Apparatus:3 clean iron nails; test tubes; test tube holder;

[03:28.51]cotton wool; oil; Bunsen burner.

[03:34.33]Iron in dry air keep air out of the water. Method

[03:37.56](1) Put some iron nails at the bottom of a test tube.

[03:43.59](2) Push some cotton wool down the tube. (3) Leave the tube for one week.

[03:53.91]Result After one week, the nails have not rusted.

[04:00.44]Conclusion Iron does not rust in dry air.

[04:07.73]Iron in air-free water Method

[04:12.14](1) Half-fill a test tube with water. (2) Boil the water for three minutes.

[04:21.20](This makes sure there is no air in the water.)

[04:25.45](3) Put two or three clean nails in the water.

[04:31.37](4) Add some oil to the water. This will keep air out of the water.

[04:38.90](5) Leave the tube for one week.

[04:44.06]Result The nails do not rust in the tube with air-free water.

[04:52.02]Conclusion Iron does not rust in air-free water.

[04:59.31]Iron in ordinary water Method

[05:04.86](1) Half-fill a test tube with water and add two or three clean nails.

[05:14.89](2) Leave the tube for one week.

[05:19.70]Result The nails rust in the tube with ordinary water.

[05:27.35]Conclusion Iron rusts in ordinary water.

[14:13.39]MODULE 6 The internet and telecommunications

[14:21.54]READING AND VOCABULARY

[14:23.87]1.Work in pairs. Read and answer the questions.

[14:29.73]1 What is the Internet? 2 How did it start?

[14:36.52]3 What is the World Wide Web? 4 Who invented it?

[14:44.61]The Internet is the biggest source of information in the world,

[14:49.27]and it's accessible through a computer.

[14:52.86]It consists of millions of pages of data.

[14:57.77]In 1969, DARPA, a US defence organisation developed a way

[15:04.15]for all their com- puters to "talk" to each other through the telephone.

[15:09.22]They created a net- work of computers called DARPANET.

[15:14.84]For fifteen years, only the US army

[15:18.32]could use this system of communication.

[15:21.71]Then in 1984, the US National Science Foundation

[15:26.72](NSF) started the NSFNET network.

[15:32.20]It then became possible for universities to use the system as well.

[15:37.81]NSFNET became known as the Inter-Network or "Internet".

[15:46.20]The World Wide Web (the web) is a computer network

[15:51.02]that allows computer users to access information

[15:54.31]from millions of websites via the Internet.

[15:58.50]At the moment, about 80 percent of web traffic is in English,

[16:03.22]but this percentage is going down.

[16:06.36]By 2020, much web traffic could be in Chinese.

[16:12.72]The World Wide Web was invented in 1991 by an English scientist,

[16:18.45]Tim Berners-Lee. Berners-Lee built his first computer

[16:23.45]while he was at university using an old television!

[16:28.06]He came up with the idea of the World Wide Web in 1989

[16:32.72]while he was working in Switzerland.

[16:36.27]Derners-Lee made it possible for everyone to use the Internet,

[16:40.22]not just univer- sities and the army. He designed the first "web browser",

[16:46.24]which allowed computer users to access documents from other computers

[16:52.00]From that moment on, the web and the Internet grew.

[16:56.56]Within five years, the number of Internet users rose

[17:00.97]from 600,000 to 40 million.

[17:05.26]The Internet has created thousands of millionnaires,

[17:09.06]but Berners-Lee is not one of them.

[17:12.51]Everyone in the world can access the Internet

[17:15.43]using his World Wide Web system.

[17:18.62]He now works as a lecturer

[17:20.54]at Massachusetts Institute of Technology in Boston.
