问题     Every second, 1 hectare (公顷) of the world’s rainforest is destroyed. That’s equivalent to two football fields. This Manning rate of destruction has serious consequences for the environment. Much of Canada’s forestry production goes towards making pulp (纸浆) and paper. If these paper products could be produced in some other way, Canadian forests could be preserved. Recently, a possible alternative way of producing paper has been suggested by agriculturalists and environmentalists: a plant called hemp.
    Hemp has been cultivated by many cultures for thousands of years. For centuries, it was essential to the economies of many countries because it was used to make the ropes and cables used on sailing ships. Nowadays, ships’ cables are usually made from wire or fibers, but scientists are now suggesting that the cultivation of hemp should be brought back for the production of paper and pulp. According to its supporters, four times as much paper can be produced from land using hemp rather than trees.
    However, there is a problem: hemp is illegal in many countries of the world. This plant is a species of cannabis (大麻), related to the plant from which marijuana (大麻毒品) is produced. In the late 1930s, a movement to ban the drug marijuana began to gather force, resulting in the eventual banning of the cultivation not only of the plant used to produce the drug, but also of the commercial fiber-producing hemp plant. Any American growing the plant today would soon find himself in prison—despite the fact that marijuana cannot be produced from the hemp plant, since it contains almost no THC (the active ingredient in the drug).
    In recent years, two major movements for legalization have been gathering strength. One group of activists believes that all cannabis should be legal—both the hemp plant and the marijuana plant. They argue that marijuana is not dangerous or addictive. The other legalization movement is concerned only with the hemp plant used to produce fiber; this group wants to make it legal to cultivate the plant and sell the fiber for paper and pulp production. This second group has had a major triumph recently: in 1997, Canada legalized the fanning of hemp for fiber. For the first time since 1938, hundreds of farmers are planting this crop, and soon we can expect to see pulp and paper produced from this new source. [br] Why was hemp banned in the United States?
选项 A、Because it can produce marijuana.
B、Because it is poisonous.
C、Because it is related to the marijuana plant.
D、Because it is harmful to human body.
答案 C
解析 文章第三段提到“This plant is a species of cannabis, related to the plant from which marijuana is produced.”这种植物是大麻的一种，与能够制成大麻毒品的作物有关。这里我们需要明确的是并非所有称之为“大麻”的植物都能被制成毒品，hemp就是这样。尤其文章第三段更进一步明确指出“marijuana cannot be produced from the hemp plant”，所以，说hemp能够产生大麻毒品、有毒或对人体有害，都是没有依据的说法，因此，本题选择C。
