Passage OneQuestions 21 to 25 are based on the following passage.During the early years of this century，wheat was seen as the very lifeblood of Western Canada. When the crops were good，the economy was good；when the crops failed. there was depression. People on city streets watched the yields and the price of wheat with almost as much feeling as if they were growers. The marketing of wheat became an increasingly favorite topic of conversation.War set the stage for the most dramatic events in marketing the western crop. For years farmers mistrusted speculative(投机的)grain selling as carried on through the Winnipeg Grain Exchange. Wheat prices were generally low in the autumn，but farmers could not wait for markets to improve. It had happened too often that they sold their wheat soon after harvest when farm debts were coming due，only to see prices rising and speculators getting rich. On various occasions，producer groups asked for firmer controls，but governments had no wish to become involved，at least not until wartime wheat prices threatened to run wild.Anxious to check inflation(通货膨胀)and rising living costs，the federal government appointed a board of grain supervisors(监视员)to handle deliveries from the crops of 1917 and 1918. Grain Exchange trading was suspended，and farmers sold at prices fixed by the board. To handle the crop of 1919，the government appointed the first Canadian Wheat Board，with full authority to buy，sell. and set prices.The author uses the term “lifeblood” to indicate that wheat was______.A. difficult to produce in large quantitiesB. susceptible to many parasites(寄生虫)C. essential to the health of the countryD. expensive to gather and transport

Passage FiveIn America, every student in his or her second year of high school is required to take a class in driver's education.The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver's side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over.After a student has passed the driver's education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), he must take his driver's test. The person must pass all three tests in order to be given a driver's license. If the person does well in his or her driver's education class, he or she will pass the test with flying colors and get a driver's license.51. In America, the driver's course mentioned above______.A. is considered as part of the advanced educationB. is given to anyone wanting to get a driver's licenseC. is carried on after students graduate from high schoolD. is offered to all the students of Grade 2 in high school

The soybean prices ended higher this Monday as traders expect supplies to remain tight
The actively traded July contract for soybeans rose 20 cents to settle at $14.85 a bushel.
The U.S government’s weekly prediction for soybean exports was higher than traders expected, said Mike Zulo, president of a consulting company in Atchison Kansas
Supplies for beans have been extraordinarily tight as China’s demand for soybean continues to increase even as U.S production stays relatively steady he said Soybean prices have risen 15 percent this year
“That U.S.D.A. number caused the trade to refocus on just how razor-thin supplies are heading in to next fall’s harvest” Zulo said
What can be inferred from the passage about next fall’s soybean harvest?A. It’s not worth noticing
B. It will rise 15 percent
C. It’s still uncertain
D. It will be razor-thin

Genetically Modified FoodEver since they were first put on the market in the early 1990s,genetically modified(GM，转基因）foods have been increasingly developed and marketed in many countries in the world, mainly on the basis of their promise to end the worldwide food crisis.______(46)Even if it would,is it the best solution?Despite what it promises,GM technology actually has not increased the production potential （潜力）of any crop.______(47)For instance,a report that analyses nearly two decades of research on major GM food shows that GM engineering has failed to significantly increase US crop production.______(48)While GM seeds are expensive,GM companies tell farmers that they will make good profits by saving money on pesticides（杀虫剂）.On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops."The promise was that you could use less chemicals and boost production.But neither is true,"said Bill Christison,President of the US National Family Farm Coalition.At the same time,the authors of the book World Hunger:Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production. ______(49)These indeed deserve our efforts and money. Meanwhile,the rise in food prices results from the increased use of crops for fuel rather than food shortage,according to a 2008 World Bank report.______(50)Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger,because better ways out are available,among which "green"farming is supposed to be the first choice._______（49）A:Problems come from food distribution and politics.B:But can GM technology solve world hunger problems?C:In fact,studies show that the most widely grown GM crop has suffered reduced productivity.D:As a matter of fact,scientists see better ways to feed the world.E:Something else,however,has been on the rise.F: GM has many benefits when it was used at the beginning.

问答题The world economy has run into a brick wall. Despite countless warnings in recent years about the need to address a looming hunger crisis in poor countries and a looming energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the past two years, and oil prices have more than tripled since the start of 2004. These food-price increases combined with soaring energy costs will slow if not stop economic growth in many parts of the world and will even undermine political stability, as evidenced by the protest riots that have erupted in places like Haiti, Bangladesh and Burkina Faso. Practical solutions to these growing woes do exist, but we'll have to start thinking ahead and acting globally. The crisis has its roots in four interlinked trends. The first is the chronically slow productivity of farmers in the poorest countries, caused by their inability to pay for seeds, fertilizers and irrigation. The second is the misguided policy in the U.S. and Europe of subsidizing diversion of food crops to produce biofuels like corn-based ethanol. The third is climate change: take the recent droughts in Australia and Europe, which cut the global production of grain in 2005 and 2006. The fourth is the growing global demand for food and feed grains brought on by swelling populations and incomes. In short, rising demand has hit a limited supply, with the poor taking the hardest blow. So, what should be done? Here are three steps to ease the current Crisis and avert the potential for a globa1 disaster. The first is to scale-up the dramatic success of Malawi, a famine-prone country in southern Africa, which three years ago established a special fund to help its farmers get fertilizer and high-yield seeds. Malawi’s harvest doubled after just one year. An international fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion in all. Such a fund could fight hunger as effectively as the Global Fund to fight AIDS, TB and Malaria is controlling those diseases. Second, the U.S. and Europe should abandon their policies to subsidizing the conversion of food into biofules. The U.S. government gives farmers a taxpayer-financed subsidy of 51 cents per gal of ethanol divert corn from the food and feed-grain supply. There maybe a case for biofuels produced on lands that do not produce foods—tree crops (like palm oil) , grasses and wood products—but there’s no case for doling out subsidies to put the world’s dinner into the gas tank. Third, we urgently need to weatherproof the world’s crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pond—which collects rainwater to be used for emergency irrigation in a dry spell—can make the difference between a bountiful crop and a famine. The world has already committed to establishing a Climate Adaptation Fund to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise.
