Passage One
Questions 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.

I'm hardly alone, which is bad news for the world's oceans. Partly because more and more sushi is demanded, we're fast fishing out our seas. Some researchers estimate that if we don't change the way we harvest the oceans, all the commercial fisheries (捕鱼业) in the world could disappear as early as 2048. That could mean no more fish to buy in your local supermarket.
Fortunately, scientists are looking for ways to fish sustainably (可持续地). One method is a quota system that sets a limited amount to every fisherman or corporation who wants a share of the total catch for certain sea area. These catch shares get rid of the possibility to over fish.A recent study in Science found that the system can prevent fishery from dying and even make it better over time. "It's truly a win-win situation," says Steven Gaines, a marine biologist at the University of California at Santa Barbara and one of the study's co-authors.
Consumers also can help save the seas through the fish they buy. California's Monterey Bay Aquarium Institute is coming out with pocket guides to sustainable sushi. The researchers base their ratings on the health of a wild fish's population as well as the impacts of fish-farming operations. Oysters, for example, grow fast and can be farmed sustainably, but salmon can't. The researchers also take fishing practices into consideration: catching big-eye tuna (金枪鱼) can cause its nearby fish to die, which certainly no one wants to see. It is hoped that, by making the right choice, consumers can encourage businesses to fish in a more sustainable way.
