阅读《威尼斯商人》(节选),完成下列各题。
  巴萨尼奥 初次的冒犯,不应该就引为仇恨。
  夏洛克  什么!你愿意给毒蛇咬两次吗?
  安东尼奥 请你想一想,你现在跟这个犹太人讲理,就像站在海滩上,叫那大海的怒涛减低它的奔腾的威力,责问豺狼为什么害得母羊为了失去它的羔羊而哀啼,或是叫那山上的松柏,在受到天风吹拂的时候,不要摇头摆脑,发出簌簌的声音。要是你能够叫这个犹太人的心变软——世上还有什么东西比它更硬呢?——那么还有什么难事不可以做到?所以我请你不用再跟他商量什么条件,也不用替我想什么办法,让我爽爽快快受到判决,满足这犹太人的心愿吧。
  巴萨尼奥 借了你三千块钱,现在拿六千块钱还你好不好?
  夏洛克  即使这六千块钱中间的每一块钱都可以分做六份,每一份都可以变成一块钱,我也不要它们;我只要照约处罚。
  公爵   你这样一点没有慈悲之心,将来怎么能够希望人家对你慈悲呢?

It’s interesting that the arrival of snow has a different effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others it is a catastrophe (灾难).

There are countries between these two extremes that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one such country, for which the arrival of snow quite simply creates problems. Within hours of the first snowfall, however light, roads are blocked, trains and buses stop in the middle of traffic. Normal communications are affected as well, telephone calls become difficult and the post immediately takes more time than usual. Almost within hours, there are also shortages(缺乏) –bread, vegetables and other things – not because all these things can no longer be produced or sent to shops, but mainly because people are frightened, and go out to store up these commodities, “just for fear that something bad should happen.”

Why then does snow have this effect? After all, the Swiss, Austrians and Canadians don’t have such problems. It is simply because there is not enough plan and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow ploughs and machines to spread salt. The reason why a country like Britain does not buy some ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospital education or helping the old.
