剑桥雅思10 Test4 Section4听力答案解析
第31题答案:C
对应原文:However, all new technologies have their teething problems. And with nanotechnology, society often gets the wrong idea about its capabilities
答案解析:录音中提到,对于纳米技术而言,社会对它的能力存在错误认知,即被公众所误解,由此确定C为答案。选项A和B在录音中确实有出现,但这些都是科幻小说和电影呈现的错误认知,因此统统排除。
第32题答案:B
对应原文:So how do we safeguard such a potentially powerful technology? Some scientists recommend that nano-particles be treated as new chemicals with separate safety tests and dear labelling
答案解析:这道题是典型的句义替换,需要大家文章来自老烤鸭雅思理解听到的内容并进行总结之后才能选出正确答案。录音中提到,一些科学家推荐,纳米粒子参照新的化学用品,需要进行独立的安全测试和标注。即要特别小心才行,由此确定B为答案。
第33题答案:C
对应原文:But as far as I’m concerned there’s a need to plough ahead with the discoveries and applications of nanotechnology
答案解析:这道题的难点在于好多同学不认识plough ahead(努力向前)这一短语的含义。但即便如此,我们也可以根据有关新技术的常识选出C为答案。
第34题答案:metal/metals
对应原文:Thanks to nanotechnology, there could be a major breakthrough in the field of transportation with the production of more durable metals
答案解析:听到transport意识到答案即将到来,more durable与stronger同义替换,由此确定答案为metals。这里面有两个注意点:一是小标题与答案之间距离过近;二是比较级的替换。
第35题答案:space
对应原文:Those same improved capabilities will dramatically reduce the cost of travelling into space making it more accessible to ordinary people and opening up a totally new holiday destination.
答案解析:听到上一行结尾的ligher in weight意识到答案即将到来。空后提示词travel改变词性放在答案之前,只要跟上节奏就不难锁定space。
第36题答案:memory
对应原文:We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory
答案解析:faster在录音中原词出现,提示答案即将到来。虽然空前词greater与a million times more的同义替换不太好识别,但memory有明显重读,提示我们要注意它。
第37题答案:solar
对应原文:The cost of solar cells will be drastically reduced so harnessing this energy will be far more economical than at present.
答案解析:这道题偏难一些。如果仅仅根据修饰关系的话,很容易认为harnessing是答案。但从题干句义推测,空上应该是某种具体的能源形式,由此锁定solar。不过solar读的很轻,也没有明显停顿,不太好识别。
第38题答案:oil
对应原文:this new technology could help with the clean-up of environmental disasters as nanotechnology will allow us to remove oil and other contaminants from the water far more effectively
答案解析:从题干可以推测,空上填的应该是种具体的污染。而这一小部分中唯一提到的污染就是oil,由此确定答案。
第39题答案:waste
对应原文:In terms of production, this means that you only use what you need and so there wouldn’t be any waste
答案解析:production与manufacturing同义替换,提示答案即将到来。根据否定锁定waste。
第40题答案:tests
对应原文:How we detect disease will change as tiny biosensors are developed to analyse tests in minutes rather than days.
答案解析:虽然空前修饰词analysis只是进行了简单的词性替换,但因为没有其他提示词,所以答案出现的有些突然,很容易反应不过来。
