Thirsty in Karachi

After two weeks in Karachi, I'm not sure whether to laugh or to cry. Either way, it involves water-or rather the lack of it.
In Western Europe or the US, you only have to turn on the tap and you'll see a jet of cold water, ready to drink, cook and bathe in, or wash the car. Turn on the tap in Karachi and you'll be lucky to fill a few buckets. Until 1947 the city was part of British India, whose engineers built and maintained a modest water supply network for the city's 500,000 inhabitants. Today, Karachi is home to around 12 million people. Half of them live in slum townships, with little or no water through the mains. Even the "rich"
Half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.
According to the state-owned Karachi Water and Sewerage Board, the city needs more than 2,500 million litres of water each day. The board currently supplies 1,650 million litres of which nearly 40 per cent is lost from leaks-and theft. Leaks are dime a dozen to water utilities the world over, but theft?
Karachi's unlikely water pirates turn out to be ordinary families struggling to get adequate supplies of one of life's necessities. Stealing water takes many forms. The simplest is to buy a suction pump and get it attached to the water pipe that feeds your house from the mains. This should maximize your share of water every time the board switches on the supply. When the practice started 20 years ago, the pumps would be carefully hidden or disguised as garden ornaments. These days people hardly bother. The pumps are so widespread and water board inspectors so thin on the ground that when officials do confiscate a pump its owner simply buy a replacement.
Insisting that people obey the law won't work because most households have little alternative hut to steal. For its part, the Karachi Water and Sewerage Board says it would dearly like to make life easier, but finds itself mired in debt because most residents either won't pay water charges or can't afford to the Urban Resource Centre, a Karachi-based think tank, of the 1.2 million known consumers of water only 750,000 are billed, of whom just 163,000 actually pay for their supplies. The board makes a perpetual loss, and there is no money to improve the system or even plug the leaks. Worse, the board increasingly relies on international loans from institutions such as the Asian Development Bank, which only makes its debt worse.
The joke is that the owners of the suction pumps end up with little-if any-extra water. You house is in a line with 20 other households all tapping into one horizontal pipeline. All you can end up doing, given you have pumps of equal strength, is redistribute each other's entitlement and pay higher electricity bills into the bargain.
Back home in London, I'll remember not to complain about the water meter, or the hosepipeban.

单选题 According to the passage, people in Karachi today suffer from a short supply of water because ______.
【正确答案】 C
【答案解析】根据第二段的内容,卡拉奇的供水系统还是在1947年以前建造的,当时的城市人口只有50万,而现在的人口猛增到1,200万。除去其中大约一半的穷人住在贫民窟,基本上没有供水外,余下的大约600万所谓富人也大大超过了原来的50万人口,当然令供水系统不胜负担。
单选题 Now people in Karachi do not hide or disguise the suction pumps they use to steal water because ______.
【正确答案】 D
【答案解析】原文中的第四段中有这样一段话:When the practice started 20 years ago, the pumps would be carefully hidden or disguised as garden ornaments. These days people hardly bother. The pumps are so widespread and water board inspectors so thin on the ground that when officials do confiscate a pump its owner simply buy a replacement.这段话清楚地说明20年前当地的居民细心地把水泵伪装成花园里的装饰,但现在已经没有人再去操这个心了,原因在最后一句话里讲得很清楚:水泵已经很普遍,来检查的人又少,一旦被充公了,再买一个就行了。
单选题 Confronted with a severe shortage of water supply, the city's Water and Sewerage Board______.
【正确答案】 A
【答案解析】不能说供水排水局不作任何努力,因而可排除B;文中第五段的一句话Insisting that people obey the law won't work说明C也不对;D的内容文中根本没有提到。事实上第五段的后半部分里讲到,该机构向亚洲发展银行这样的机构贷款以改进供水系统,只是结果不理想,因此答案是A。
单选题 Which of the following is true of the owners of the suction pumps, if their neighbors have equally powerful pumps as they do? ______
【正确答案】 B
【答案解析】本题的答案可在第六段中找到。这段的第一句话就否定了A,little几乎没有;C的意思是把自己得到的水和邻居们分享,但事实上并非如此,文中说的是All you can end up doing, given you have pumps of equal strength, is redistribute each other's entitlement...注意句中given的用法相当于if,引导一个条件从句,即如果大家的水泵功率相同,那么结果只能是把各家应得的水重新分配而已;D的内容文中没有讲到;B的内容则在...pay higher electricity bills into the bargain表达了,是正确答案。
单选题 Which of the following is true about the author when he is back home in London? ______
【正确答案】 C
【答案解析】这句话的意思是“对伦敦的供水情况心满意足”。Remember not to complain about:“记住不抱怨……”伦敦也有缺水的时候,但有过卡拉奇的经历,作者对伦敦的限水再不会抱怨了。A和B的内容文中均没有讲到;D则与正确答案内容相反。
