Much of Canada’ s forestry production goes towards making pulp and paper. According to the Canadian Pulp and Paper Association, Canada supplies 34% of the world’ s wood pulp and 49% of its newsprint 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. It produces fibre which can be made into paper, fuel, oils, textiles, food, and rope. 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; colonial expansion and the establishment of a world - wide trading network would not have been feasible without hemp. Nowadays, ships’ cables are usually made from wire or synthetic fibres, but scientists are now suggesting that the cultivation of hemp should be revived for the production of paper and pulp. 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 fibre, rope, oil, fuel and textiles, is a species of cannabis, related to the plant from Which marijuana 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 fibre - producing hemp plant. In fact, marijuana cannot, be produced from the hemp plant, since it contains almost no THC (the active ingredient in the drug).
In recent years, a movement for legalization have been gathering strength. It is concerned only with the hemp plant used to produce fibre; this group wants to make it legal to cultivate the plant and sell the fibre for paper and pulp production.
Why was hemp banned?
选项
A、It is related to the marijuana plant.
B、It can be used to produce marijuana.
C、It was no longer a useful crop.
D、It was destructive to the land.
答案
A
解析
原文第三段第二句话“This plant,so useful for fibre, rope,oil,fuel and textiles,is a species of cannabis,related to the plant from which marijuana is produced”说这种植物非常有用,可以制成纤维、绳索、油类、燃料和织物,但它是大麻属的一种植物,与制成大麻毒品的植物种类相近,所以答案A是正确答案。原文中还说麻并不能制造大麻毒品,因此答案 B麻可以制成大麻毒品明显是错误的,C麻不再有用也与原文不符,D麻对土地具破坏性在原文中并未提到,相反种麻可以减少树木砍伐量,从而保护环境。
