　　Passage Two

　　Questions26to30arebasedonthefollowingpassage.

　　Hemp(大麻)has been cultivated by many cultures for thousands of years. It can be made into paper, fuel, oils, textiles, food and rope. For many centuries, it was essential to the economies of many countries because it was used to make the ropes and cables used on sailing ships; colonial expansion and the establishment of a worldwide trading network would not have been possible without hemp. Nowadays, ships’ cables are usually made from wire or synthetic fibers, but scientists are suggesting that the cultivation of hemp should be revived for the production of paper and pulp(紙漿). According to its proponents, four times as much paper can be produced from land using hemp rather than trees, and many environmentalists believe that the large-scale cultivation of hemp could reduce the pressure on Canada’s forests.

　　However, there is a problem: hemp is illegal in many countries of the world. This plant, so useful for fiber, rope, oils, fuel and textiles, is a species of cannabis(大麻制品), 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. Although both George Washington and Thomas Jefferson grew hemp in large quantities on their own land, any American growing the plant today would soon find himself / herself 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 believe that ALL cannabis should be legal —both the hemp plant and the marijuana plant —and that the use of the drug marijuana should not be an offense. They argue that marijuana is not dangerous or addictive, and that it is used by large numbers of people who are not criminals but productive members of society. They also point out that marijuana is less toxic than alcohol or tobacco. 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 farming 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.
