Text 4Could 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 -80, when they also almost tri- pled. Both previous shocks resulted in double - digit inflation and global economic decline. So there are the headlines warning of gloom and doom this time?The oil price was given another push up this week when Iraq suspended oil experts. Strengthening economic growth, al the' same time as winter grips the northern hemisphere, could push the price higher still in the short Item.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 Europe, tuxes account for up to four - fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past.Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the 'oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, oil prices averaged $ 22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25 - 0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted—have become more energy-intensive, and se could he more seriously squeezed.One more reason net to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%.36. The main reason for the latest rise of oil price is______.A) global inflationB) reduction in supplyC) fast growth in economyD) Iraq' s suspension of exports

Feed the World with Potatoes
1. As food prices continue to rise rapidly,there is growing concern about the effect it will have among the world’s poor.
2. Increasingly, experts are looking to thepotato as a possible low-cost solution to feeding the hungry. To emphasize the issue, the United Nations has called the potato “a hidden treasure” and named 2008 the International Year of the Potato. Here’s how potatoes could end the food crisis.
3. The potato matures more quickly, on less land and in harsher climate than most other major crops. Up to 85 percent of the plant is eatable, compared with around 50 percent of cereals. Its broad adaptability to a wide variety of farming systems is also note worthy.
4. Potatoes are an excellent source of complex carbohydrates, which is release their energy slowly, and have only 5 percent of wheat’ s fat content. They contain only a quarter of the calories of bread and,according to the Potato Center, when boiled, potatoes have more protein and nearly twice the calcium as corn. Additionally, they are good source of vitamin C, iron, potassium(钾)and zinc(锌).
5. The food and Agriculture Organization recently surveyed food price inflation in over 70 of the poor countries. Cereal price inflation was much higher and far more widespread than for potatoes. A significant factor behind the potato’ s affordability is the fact that unlike other agriculture products, the potato is not yet a global commodity, and has therefore not attracted speculative investors. Raw potatoes are heavy and carrot during transmit, so global trade has been show to take off. Also, potatoes are susceptible(易受影响的) to infection with disease, hindering(阻碍) export. According to analysts’ estimates, less than 5 percent of potatoes are traded internationally, with prices driven primarily by local tastes instead of international demand.

B. Major Food Crops
C. Healthy Food

问答题Directions:In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in a maximum of 10 words. Remember to write the answers on the Answer Sheet. Questions 1-5 are based on the following passage. 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 term. 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 Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25-0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted—have become more energy-intensive, and so could be more seriously squeezed.

A sizable portion of the world is only just emerging from economic decline. The economist’s commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%. Questions: 1．What is the main reason for the latest rise of oil price? 2．What are the results of the 1970s’ oil shock? 3．It can be inferred from the text that the retail price of petrol will go up dramatically if ________. 4．According to the passage, reduction in oil consumption is due to ________, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries. 5．According to the passage, compared with those in the 1970s, oil-price shocks are ________ now.
