　　四级听力第一套听力解析

　　本次大学四级听力试题难度始终，大部分题目仍然遵守所听既所得的原则。新闻考察的内容包括为第一篇是环保篇，为船舶交通所导致的大气污染问题;第二篇员工权益篇，探讨了超市员工人身安全在安保撤出后所面临的困境;第三篇是生活趣事，讲述了一起巧克力货车侧翻的原因和后续。长对话第一篇在消费主义的背景下富有思辨性，且紧贴电子支付的时代热点;第二篇是常规的售后服务类话题。短文内容为日常生活类(家居收纳)、好人好事类和现代技术类。

　　Section A

　　News Report 1

　　第一篇新闻报道讲的是船运所导致的大气污染问题，属于环保类话题。文章难度适中，没有专业性很强的名词。新闻的第一句话为新闻导语，简洁概括了新闻主旨，“pollution from ships”点明了本段听力的核心词，并为引出第1题的答案作了铺垫。本题难点在于学生能否识别出“are signs of ship traffic blow”是“are results of ship traffic blow”的同义替换，找出隐含的因果关系，并结合上一句的Atlantic选出正确选项。第2题考查NASA工作人员的观点，原文中有“according to NASA officials”作为明显定位词，所听既所得。但小心这类引用某人说的话时，一般先出说话内容再点明说话人，学生可能会只听到说话人是谁，而忽视前面他所说的内容。

　　原文：

　　A NASA satellite orbiting over Portugal took photographs that reveal the effects of pollution from ships. One of the photos shows the thin film of clouds above the brilliant blue of North Atlantic cut by white lines of thicker clouds that look like scars. [1] NASA officials explained those thicker clouds are signs of ship traffic blow. when ships power their ways through the ocean, they pump exhausts into the atmosphere, just as cars do. And those massive amounts of particles can cause clouds to form. Get enough of those particles in one place, as from the exhausts of the ship, and they can lead to the creation of new clouds easily visible from space, these clouds can be huge. Some of them stretch hundreds of kilometers from end to end, NASA officials said. [2] It’s likely that these sorts of clouds are having some effect over global climate, according to NASA officials. But scientists are not yet sure what effects it has.

　　Q1: What has caused the figure clouds in a photo taken by a NASA satellite?

　　Q2: What do NASA officials think about the figure clouds?

　　News Report 2

　　第二篇新闻报道聚焦于超市员工的人身安全问题。针对郊区超市撤离了安保这件事，超市员工和雇主之间各执一词。第3题通过选项清一色的“to do”结构，可以对题目进行预测，应该是询问目的类的信息。听力时，把握“to do sth. /for sth.”等用于表目的的关键词即可。第4题询问超市发言人(即雇主方)的说法，注意捕捉题干关键词“spokesman”，以及重要的转折词“however”后面常常是答案出现处。本篇总体难度为3篇新闻中最小的，做第4题时注意明确选项代词it指代的对象。

　　原文：

　　Staff at a suburban supermarket in Melbourne say they feel unsafe at work after security guards were removed. This came after a series of physical attacks and verbal abuse by customers. [3] More than 50 workers at the store have signed a letter calling for a permanent security guard following a series of incidents, including a customer threatening to attack a supervisor with a knife. "A security worker had guarded the store each night from 7pm until 12am, but that had stopped suddenly on Monday,” employees said. One worker said an angry customer had thrown a chicken at his head after complaining about how long she had waited to be served. Another worker said the lack of protection at the store made her feel uncomfortable at work. [4] However, the spokesman of the supermarket said the store had taken strong action in response to incidents, "We have found very few instances of bad customer behavior at our store in the past year. In the rare cases, we have seen bad behavior, we have taken strong action in response, including banning a customer from the store."

　　Q3: For what purpose, did the staff at the supermarket in Melbourne sign a letter?

　　Q4: What did the spokesman of the supermarket say, regarding the employees' demand?

　　News Report 3

　　第三篇新闻报道是关于一起发生在波兰华沙的交通事故。由于该事故是由一辆装载巧克力浓浆的货车侧翻引起的，因此内容上会比较有趣味性，听起来不太枯燥。第5题的答案出现在开头首句的导语部分，“drivers、Warsaw、find”这3个题干关键词均在原文重现，答案项的“road、blocked”也没有改写。较之于考查同义替换的题目，难度较小。第6题这种“what do xx say about…”类的题目是典型的细节题，延续了上一题的风格，同样没有任何改写，捕捉到“barrier”和“overturned”两个关键词即可选出正确答案。本篇报道的难点在于答案句出现的位置过于集中，第5题的答案出现之后，紧接着就是第6题的答案，没有给考生一丝喘息的机会，可能会错过。若错过，可运用排除法，结合下文删去其他三个有悖于原文的选项。

　　原文：

　　[5] Drivers on their way to the Polish capital of Warsaw on Wednesday morning found the road blocked by an unusual obstacle, tons of liquid chocolate that spilled onto the motorway. [6] A track carrying the sweet load hit a road barrier and overturned, blocking two lames. The cracked tank spilled a pool of rapidly hardening chocolate which quickly covered the width of the road. While the drives was taken to hospital with the broken arm, firefighters struggled to remove a reported 12 tons of solid chocolate from the road. A representative for the firefighters told the local TV that removing the chocolate was worse than dealing with snow. After contacting the chocolate manufacturer, the firefighter resorted to spraying hot, pressurized ice water to get rid of the sticky substance. The local TV also noted that the clean-up spanned more than a mile because drivers simply drove through the chocolate after the crash, leaving a long chocolate trail. But despite the sticky situation, firefighters and police attending to the clean-up were reportedly cheerful about the long task ahead. After all, who could be mad about 12 tons of chocolate?

　　Q5: What do the drivers on the motorway of Warsaw find?

　　Q6: What does the reporter say about the accident?

　　Question 7: What does the firefighters representative tell the local TV?
