剑桥雅思6 Test 2 Section 4听力答案解析
第31题答案：A
对应原文：all the hooves were off the ground in some of the photos
答案解析：这道题唯一的难点在于识别hooves和feet的同义替换。不过录音中稍靠前面提示了four feet or hooves，所以难度不算太大。
第32题答案：B
对应原文：moving pictures and then put all the existing technologies together to make the first entire motion picture system
答案解析：录音中虽然确实提到了Edison，但只是说爱迪生雇佣了这个人，没有提到技术是否是他发明的。选项C完全没提到。而选项B中available与existing对应，first与new对应，因此判断答案为B。
第33题答案：C
对应原文：The camera weighed over 200 kilograms and only one person at a time could see the film.
答案解析：原文中确实提到了选项A中的only one person，但说的是同一时间只有一个人能看，而非一个人能拍。选项B完全没有提到。选项C中的very heavy则是被替换成了具体的数字，由此确定答案。
第34题答案：A
对应原文：Well now, news of the new system in America travelled fast and a number of rival European systems started to appear once people had heard about it.
答案解析：题目本身并不难，考点仅仅是be told about与heard的同义替换而已，但因为答案离上一道题目很近，稍微犹豫一些就会错过。
第35题答案：A
对应原文：Then in 1895, three systems were all developed, more or less at the same time and independently of each other. I guess the most famous of these was by the Lumière Brothers from France
答案解析：首先，录音中明确提到了independently of each other，即互相独立完成，因此排除选项B。其次，cinema来源于法国人发明的系统，而非德国人，同样排除。因此确定答案为A。
第36题答案：C
对应原文：A continuing problem at the time was that the films had a tendency to break when they were being played – a problem which was caused by the tension between the two wheels, or ‘reels’ as they are called, which hold the film.
答案解析：这道题稍微需要一些背景知识。最起码得了解放映机一般包含两个轮子用于固定胶片，然后就会比较好做一些。听到two wheels即可确定答案。
第37题答案：A
对应原文： the simple addition of a third reel between the two main reels, and this took all the tension away with the result that the film stopped snapping
答案解析：录音中提到的是加了第三个轮子，而非加三个轮子，因此排除B。C选项完全没提到。而A选项中的remove被替换成take away，因此判断答案为A。
第38题答案：Great Train Robbery
对应原文：and this led to the making of The Great Train Robbery – the very first movie made
答案解析：解题存在两个障碍。一是题目采用了语序颠倒的出题方式，本应在前面起提示作用的first被放在了答案后面。二是great train robbery作为专有名词，无法根据上下文事先推测含义。所以哪怕不少同学都听到了这一点，却没有识别出具体的词汇。
第39题答案：Sound effects
对应原文：and the first step towards this was in 1926 when sound effects were first used on a film
答案解析：答案中sound的尾音d，与effects的首音e发生连读，不太好识别。
第40题答案：poor sound quality
对应原文： I believe they put subtitles on the film – that is, they printed the dialogue along the bottom of the film to compensate for this poor sound quality
答案解析：题目存在两个难点，一是说完subtitles这一提示词之后，后面又加了一句解释，导致不少同学错误的以为答案在这一句解释中，进而忽略了后一句。二是好不容易听到答案之后只写了sound quality，漏掉了poor导致扣分。
