Passage Three
Before the grass has thickened on the roadsides and leaves have started growing on the trees is a perfect time to look around and see just how dirty Britain has become. The pave- ments are stained with chewing gum and the ditches are full of discarded fast food packets. Years ago I remember traveling abroad and being saddened by the plastic bags and discarded bottles. Nowadays, Britain seems to look at least as bad. What has gone wrong? The problem is that the rubbish created by our increasingly mobile lives lasts a lot longer than before. If it is not cleared up and properly thrown away, it stays in the undergrowth(层灌木) for years.
It is estimated that 10 billion plastic bags have been given to shoppers. These will take anything from 100 to 1,000 years to rot. However it is not as if there is no solution to this. A few years ago, the Irish government introduced a tax on non-recyclable carrier bags and in three months reduced their use by 90%. When he was a minister, Michael Meacher attempted to introduce similar arrangement in Britain. The plastics industry protested, of course. However, they need not have bothered; the idea was killed before it could draw breath, leav- ing supermarkets free to give away plastic bags.
What is clearly necessary right now is some sort of combined action, both individual and collective, before it is too late. The alternative is to continue sliding downhill until we have a country that looks like a vast rubbish tip. We may well be at the tipping point. Yet we know that people respond to their environment. If things around them are clean and tidy, people be- have cleanly and tidily. If they are surrounded by rubbish, they behave like rubbish. Now. much of Britain looks pretty dirty. What will it look like in five years?

What might be the best title for the passage?
A、 Plastic Bags
B、 Environment Protection
C、 Dirty Britain
D、 Rubbish Disposal
【正确答案】：C
【题目解析】：主旨题。通常,给文章起标题有两个线索:一是看文章的开头段;二是看文章的结尾段。在这两段都提到了 dirty、 Britian这的关键词,形成首尾呼应,同样也应该与标题照应。所以,选C. Dirty Britain【参考译文】路边绿草如茵,树叶长得茂密前,是去看一看英国有多脏的绝佳时候。人行道上沾满了口香糖,沟渠里满是丢弃的快餐包装袋。多年前,我记得在国外旅行,看见到处都是塑料袋和丢弃的瓶子,我顿感悲伤。如今,英国看起来至少和这一样糟糕。出了什么问题?问题是我们日益流动的生活所造成的垃圾比以前持续地更长久。如果不清理和适当处理,它会停留在下层灌木很多年。据估计,我们向顾客提供了100亿个塑料袋。这将需要100到1000年的时间来处理这些塑料袋。然而,这并不是解决不了的问题。几年前,爱尔兰政府对不可回收的购物袋收税,三个月内减少了90%的使用量。当 Michael Meacher还是一名部长时他试图在英国采取类似的安排。当然,塑料行业提出了抗议。然而他们不必费心了,这个想法在实施前就被遏制了,超市又可以免费赠送塑料袋了。现在显然需要的是一种联合行动,不管是个人还是集体,在为时已晚之前。另一种选择是继续走下坡路,直到我们看到一个像巨大垃圾场一样的国家。我们可能正处在临界点。然而,我们知道人们对环境的反应。如果他们周围的事物都是干净整洁的,人们就表现得干净整洁。如果人们被垃圾包围,他们的行为就会像垃圾一样。现在,英国的大部分地方看起来很脏。五年后会是什么样子?
