Part Ⅱ Reading Comprehension (35 minutes) Passage One Questions 21 to 25 are based on the following passage: 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 . 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 . 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 production.
22.Why was the plant hemp essential to world-wide trade in the past 23.Why do agriculturalists think that hemp would be better for paper production than trees 24.Why was hemp banned 25.“According to its proponents, four times as much paper can be produced from land using hemp rather than trees.” ——What does “proponents” mean 内容概要:加拿大是世界上生产纸浆和纸制品的大国。为了保护森林资源,环境学家们提出可以种植麻,用麻纤维造纸。过去人们种植麻用以制造绳索、燃料、油类等,同样面积的土地上种出来的麻造成的纸是树制成纸的四倍。然而在许多国家种植麻是违法的,尽管麻植物并不能制成毒品大麻。人们正在努力使麻种植合法化。 21.【答案】C。 22.【答案】A。 23.【答案】B。 24.【答案】A。 25.【答案】B。 |
