21、f these paper products could be produced in some other way, Canadian forests could be【 C12】 _. Recently, a possible【 C13】 _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 pr

22、oduces fibre which can be【 C14】 _paper, fuel, oils, textiles, food, and rope.

23、ot have been possible【 C17】 _hemp. Nowadays, ships cables are usually made from wire or synthetic fibres, but scientists are now suggesting that the cultivation of hemp should be【 C18】 _for the production of paper and pulp. According to its proponents, four-times as【 C19】 _paper can be produced from

24、 land using hemp rather than trees, and many environmentalists believe that the【 C20】 _scale cultivation of hemp could reduce the pressure on Canadas forests. 31 【 C1】 ( A) matching ( B) equivalent ( C) mounting ( D) reaching 32 【 C2】 ( A) great ( B) wonderful ( C) imaginary ( D) alarming 33 【 C3】 (

29、ever late in keeping an appointment. He knows that he can not get through his immense amount of work【 12】 he faithfully keeps every【 13】 promptly and deals with every piece of work【 14】 it has to be attended to. There is a【 15】 which says, “Time flies, never to be recalled.“ Time is more【 16】 than m

30、aterial things. The unpunctual man, on the other hand, never does what he has to do at the proper time. He is always【 17】 that he finds no time to answer letters, or return calls or keep appointments【 18】 . Friends sometimes grow cold towards each other, or even become enemies, because one of them h

31、as been remiss in answering letters or keeping appointments. Tile punctual man is a source of annoyance【 19】 to others and to himself. Unpunctuality, moreover, is very harmful when it comes to doing one s duty, whether public or private. Failure to be punctual in【 20】 one s appointments is a sign of

32、 disrespect towards others. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men. In the end, he loses both time and his good name. 61 Acid ran leads to fish mortality. Many species of fish cannot survive in aquatic environments there the pH is below 5.0. If t

33、he water is too acid, the gill .systems of many kinds of fish can be damaged. 【 C1】 _ , the acid alters the blood chemistry of all fish. As a result, the fish population in an acidic environment decreases 【 C2】 _ becomes extinct. Approximately 20 percent of the lakes in Scandinavia are without fish.

34、 Moreover, in Nova Scotia the 【 C3】 _ salmon industry may be threatened by the decrease of salmon in rivers and streams. The impact is also 【 C4】 _ in the waters of Ontario and Quebec, where fish populations are 【 C5】 _ the decline. What potential remedies exist for the acid rain 【 C6】 _? The expert

35、s disagree. Some say new environmental laws should be 【 C7】 _ to control the emission of pollutants in the atmosphere. Some say that if we had known how serious acid rain was, we would have planned 【 C8】 _ to prevent it. 【 C9】 _, all agree that if the consumption of fossil fuel were reduced, we woul

36、d have less of a problem. Another 【 C10】 _ is that special scrubbers could be installed in smokestacks to remove a good 【 C11】 _ of the pollutants before they get into the atmosphere. Other ideas even include breeding more 【 C12】 _ fish. And research suggests that spreading lime into lakes may be ef

37、fective in 【 C13】 _ acidity. In conclusion, it is clear that if we truly want to reduce the impact of acid rain, a 【 C14】 _ of remedies and international cooperation must be explored. It is a sad fact that acid rain probably could have been avoided if we 【 C15】 _ what we know now. 62 【 C1】 _ ( A) Li

They used to go on【 C5】_this even when they were pregnant And【 C6】 _now, if coal could not be produced without pregnant women dragging it【 C7】 _and fro, I fancy we should let them do it【 C8】 _than deprive ourselves of coal.

More than anything【 C11】_perhaps, the miner can stand as the type of manual worker, not only because it is so vitally necessary and【 C12】 _so【 C1

44、3】 _.that we are capable【 C14】_forgetting it as we forget the blood in our veins. In【 C15】 _way it is even humiliating to watch coal-miners working.
