题文

Air pollution is damaging 60% of Europe’s prime wildlife sites in meadows, forests and bushes, according to a new report.A team of EU scientists said nitrogen emissions(氮排放) from cars, factories and farming were threatening biodiversity. It’s the cond report this week warning of the on-going risks and threats linked to nitrogen pollution.Nitrogen in the atmosphere is harmless in its inert(惰性的) state, but the report says reactive forms of nitrogen, largely produced by human activity, can be a menace to the natural world.Emissions mostly come from vehicle exhausts(排气), factories, artificial fertilizers(肥料) and animal waste from intensive farming. The reactive nitrogen they emit to the air disrupts the environment in two ways: It can make acidic soils too acidic to support their previous mix of species. But primarily, becau nitrogen is a fertilizer, it favors wild plants that can maximize the u of nitrogen to help them grow. In effect, some of the nitrogen spread to fertilize crops is carried in the atmosphere to fertilize weeds, possibly a great distance from where the chemicals were first applied.The effects of fertilization and acidification favor common aggressive species like grass, brambles and nettles. They harm more delicate species like moss(苔藓), and inct-eating sundew plants.The report said 60% of wildlife sites were now receiving a critical load of reactive nitrogen. The report’s lead author, Dr Kevin Hicks from the University of York’s Stockholm Environment Institute (SEI), told BBC News that England’s Peak District had a definitely low range of species as a result of the reactive nitrogen that fell on the area.“Nitrogen creates a rather big problem that ems to me to have been given too little attention,” he said. “Governments are responsible for protecting areas like this, but they are clearly failing.” He said more rearch was needed to understand the knock-on effects for creatures from the changes in vegetation accidentally caud by emissions from cars, industry and farms. At the conference, the reprentatives agreed “The Edinburgh Declaration on Reactive Nitrogen”. The document highlights the importance of reducing reactive nitrogen emissions to the environment, adding that the benefits of reducing nitrogen outweigh the costs of taking action.小题1:The underlined word “menace” is ud to express that the reactive nitrogen, largely produced by human activity can be ___________.A．frighteningB．threateningC．uniqueD．unusual小题2: We can infer from the passage that _________.A．it’s harmless to have reactive nitrogen existing in the atmosphereB．reactive nitrogen emissions help aggressive species less than cropsC．the harm to tho delicate species has a negative impact on biodiversityD．reactive nitrogen can fertilize soils and keep their biodiversity小题3: The team of EU scientists relead the cond report of nitrogen emissions this week when __________.A．no action was taken to stop nitrogen emissionB．governments were willing to protect areas harmed by nitrogen C．“The Edinburgh Declaration on Reactive Nitrogen” was agreedD．nitrogen emissions were threatening wildlife sites’ biodiversity小题4: Which of the following would be the best title for the passage?A．Keeping Away From Nitrogen EmissionsB．Stopping Nitrogen EmissionsC．Air Pollution Damaging Europe’s WildlifeD．Saving Europe’s Wildlife 题型：未知难度：其他题型

考点

据考高分专家说，试题“Air pollution is dam.....”主要考查你对 [日常生活类阅读 ]考点的理解。 日常生活类阅读

日常生活类阅读的概念：

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。

日常生活类阅读题答题技巧：

【题型说明】该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。 【备考提醒】为了保证较高准确率，建议同学们做好以下几点： 1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。 2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。 3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。 4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
