[01:58.41]Section B
[02:00.95]Passage  One
[02:02.41]The world is not only hungry.
[02:04.60]but thirsty for water.
[02:06.25]That may seem strange to you.
[02:07.69]since nearly 75%of the earth's surface is covered with water.
[02:12.75]but about 97% of this huge amount is sea water,or salt water.
[02:18.03]Man can only drink and use the other 3% - the fresh water from river.
[02:24.35]lakes,underground,and other source.
[02:27.25]and we cannot even use all of that
[02:29.92]because some of it is in the form of icebergs² and glacier³.
[02:33.99]Even worse,some of it has been polluted.
[02:32.99]However,this small amount of fresh water is still enough for us.
[02:37.22]but our need for water is increasing rapidly.
[02:40.91]Only if we take steps to deal with the problem now.
[02:44.09]can we avoid a severe world wide water shortage⁴ later on.
[02:48.27]One of the first steps is to develop ways of reusing it.
[02:52.09]Today water is used only once and then discharged⁵ into a sewer⁶ system.
[02:57.10]and it eventually returns to the sea or runs into underground storage tank.
[03:02.48]It is possible to pipe used water to a purifying⁷ plant.
[03:06.95]There it can be filtered⁸ and treated with chemicals so that it can be used again.
[03:12.28]Even if every large city purified⁹ and reused its water.
[03:16.54]we still would not have enough.
[03:17.97]All we'd have to do to make use of the seawater in the world is to remove the salt.
[03:23.67]If we take these steps.
[03:25.11]we'll be in no danger of drying up!
[03:28.61]11. How much of the earth's water can man really use?
[03:33.73]12. How can we avoid a world wide water shortage in the future?
[03:39.71]13. Which of the following is true?
[03:42.50]Passage Two
[03:42.61]When we do some reading
[03:44.10]we often come across these names
[03:47.31]the British Isles¹⁰, Britain, Great Britain.
[03:51.08]These different names are often used to mean the same things.
[03:54.84]But do you know the difference between them?
[03:57.01]The British Isles consist of two large island
[04:00.82]one is called Ireland and the other Britain.
[04:04.35]Britain,or Great Britain
[04:07.35]is the larger of these two islands and it is divided into three parts.
[04:12.44]Scotland,Wales and England.
[04:15.89]It does not include Northern Ireland.
[04:18.66]England is the largest,most populous,and generally speaking
[04:23.31]the richest section.
[04:24.49]It is only a part of Great Britain.
[04:27.23]The importance of England is so great in Britain that some foreigners just say "England" when they mean Britain.
[04:35.20]In fact,England,Great Britain and the British Isles ought only to be used as geographical¹¹ names.
[04:44.78]14. What do the British Isles consist of?
[04:48.96]15. What is Great Britain made up of?
[04:53.17]16. What is NOT true about England according to this passage?
[04:58.45]Passage Three
[05:00.72]Many thousands of years ago
[05:02.13]people lived only in hot countries.
[05:05.08]They did not live in cold countries because they could not keep warm.
[05:08.84]Then they learned¹² how to make clothes.
[05:11.79]When an animal was killed,they cut off its skin.
[05:15.16]They wrapped the skins around their bodies.
[05:17.33]The skins kept them warm.
[05:20.02]Skins which had fur on them were the best.
[05:22.37]Even today some people wear the furs of animals to keep them warm.
[05:27.21]At first,men did not know how to make fire.
[05:30.08]Sometimes lightning would in a forest and start a fire.
[05:33.50]The people took some of this fire to make a fire near their home.
[05:37.60]A fire was very important for three reason.
[05:41.05]It kept them warm.
[05:43.35]It frightened wild animals.
[05:44.81]They did not attack them when they saw a fire.
[05:48.50]Then another thing was discovered.
[05:50.95]If you cook food,it tastes much better!
[05:54.11]17. Why did people live only in hot countries long,long ago.
[06:01.01]18. How did people keep warm later?
