Could the bad old days of economic decline be about to return Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $ 10 last December. This near tripling of oil prices calls up scary memories of the 1973 oil shock ,when prices quadrupled, and 1979-1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time
The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short tern.
Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Eu
A. global inflation

{{B}}第一篇{{/B}}
{{B}}A Thirsty World{{/B}}
The world is not only hungry; it is also thirsty for water. This seems strange to you, since nearly 75% of the earth’s surface is covered with water. But about 97% of this huge amount is from sea water, or salt water. Man can only drink and use the other 3% — the fresh water that comes from rivers, lakes, underground, and other sources. And we cannot even use all of that, because some of it is in the form of iceberg (冰山) and glaciers (冰串). Even worse, some of it has been polluted.
At the moment, this small amount of fresh water is still enough for us. However, our need for water is increasing rapidly. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water suppl

Passage Two
There was a big pile of bricks on the top of a tall building and a man had to bring them down to the ground. He had a long rope which went over a pulley (滑轮) at the roof of the building. The other end was fastened to a big box.
First he pulled the box up to the top of the building, and fastened the end of the rope so that the box could not come down. Then he climbed up the ladder and filled the box with bricks. Next he climbed down the ladder and untied the rope. Unfortunately the box of bricks was heavier than the man, and as a result he was pulled up by the rope. Half-way up, the box of bricks hit him as it was coming down.
