四六级和雅思的语速对比
四级听力原文：
A New Jersey black bear that walks upright on its 2 back legs and has become a social media darling has reemerged and has been captured on video month after its last sighting. The bear named Pedals was spotted in a town of Oakrage, in a video posted to Facebook featuring the bear it appear to be inrelatively good health and was moving quickly. “Pedals apparently hasn’t injured leg or pool that doesn’t allow it to walk comfortably on all fulls.” according to experts.

The bear would do better in its natural habitat on the agency would step in if its condition deteriorated they said.(186 单词 2017年12月卷)

而雅思同样篇幅的内容用了多长时间呢?
Well, my group has been doing a project on how household waste is recycled in Britain.We were quite shocked to discover that only 9% of people here in the UK make an effort to recycle their household waste. This is a lower figure than in most other European countries, and needs to increase dramatically in the next few years if the government is going to meet its recycling targets.The agreed targets for the UK mean that by 2008 we must reduce our carbon dioxide emissions by 12.5%, compared with 1990. And recycling can help to achieve that goal, in two main ways: the production of recycled glass and paper uses much less energy than producing them from virgin materials, and also recycling reduces greenhouse gas emissions from landfill sites and incineration plants. As part of our project, we carried out a survey of people in the street, and the thing that came up over and over again is that people don’t think it’s easy enough to recycle their waste. One problem is that there aren’t enough ‘drop-off’ sites, that is, the places where the public are supposed to take their waste.We also discovered that waste that’s collected from householders is taken to places called ‘bring banks’, for sorting and baling into loads.

雅思的听力语速比四六级的语速快了57%。四六级的学生听雅思听力感觉是rap，而雅思的学生听四六级等于0.5倍速的听力播放，就觉得语速太慢。
雅思听力题干中包含的比较类考点
雅思听力选择题比较考点第一类：直接比较
例1 剑7 Test 2 Q 34
A German study showed there was greater ‘mixed handedness’ in musicians who
A started playing instruments in early youth
B play a string instrument such as the violin
C practice a great deal on their instrument
思路透析：题干中包括greater这个明显的比较级，提醒考生们注意的是，在实际的听力中，比较级的用词可以发生同义转换，但是这种比较关系的表达一定在听力文本中是存在的，所以要特别关注在听力内容中比较的表达方式，答案就在其中。这与填空题是一致的，在填空题中如若发现比较表达方式，那我们可以把它当特殊关键词来对待，耐心等待听力素材中的比较表达后即可得到答案。
实际做题：在实际做题中，当听到Germany study 时确定做题位置。
原文：keyboard players had high levels of mixed handedness， whereas string players like violinists strongly favored one hand. Also those who started younger were more mixed handed.
解题：从原文中我们不难看出，小提琴演奏者的用手习惯比较倾向于某一侧。所以排除B。紧接着出现的整句话里出现了两处比较级，more mixed handed 与greater mixed handedness 形成同义转换，younger 与选项A中的early youth 对应，所以正确答案为A。
雅思听力选择题比较考点第二类：间接比较
例2 剑3 Test 1 Q 32
According to the speaker， the main cause of back pain in women is
A pregnancy
B osteoporosis
C lack of exercise
思路透析：在审题中发现有main cause 这样的间接比较提示词，那此题很显然要列出几个造成女性背疼的原因，但是要进行对比得出谁是主要原因。
实际做题：听到women 就确定了做题位置。
原文：The majority of our patients at the clinic tend to be women. They are especially vulnerable because of pregnancy but also because of osteoprosis， which I personally believe to be the major cause of problems for women.
解题：在原文中我们不难发现pregnancy 和 osteoprosis 是并列出现的，但是后者紧跟着就是一个非限定性的定语从句，指出后者是major cause，也就是main cause的同义转换，故答案为B。
雅思听力选择题比较考点第三类：隐含比较
例3 剑3 Test 3 Q 37
Ostrich meat
A has more protein than beef
B Tastes nearly as good as beef
C is very filling
思路透析：虽然题干较短，而且没有比较指示词，但是AB两个选项都存在着比较，故此题依然以听比较关系为重点。
实际做题：原文：Ostrich meat is slightly higher in protein than beef， and much lower in fats and cholesterol. It tastes good too. A series of European taste tests found that 82% of people prefer ostrich to beef.
解题：其实答案A 很明显，几乎是原词重现。B错误的原因是大多数人们觉得鸵鸟肉比牛肉好吃，并不是一样好吃。要注意在比较时经常加入slightly 这样的副词来修饰比较级。
总结：其实我们不难发现，在这三类雅思听力选择题比较考点中，第一类直接比较的题目还是最容易解答的，只要听准同样的比较表达方式，答案很容易得到;第二类间接比较的题目也不是太难，关键在于掌握major，majority，main，mainly等提示词并注意它们之间互相同意转换即可;第三类隐含比较还是比较难的，因为题干里虽然无比较，但是选项里有比较的特点，而且实际听力中又容易出现否定词搭配比较表达出现的形式，使学生的反映时间和速度受到极大的影响，大大降低了解题正确率。请广大“烤鸭”们一定要耐心总结，戳穿选择题中的比较考查特点，做到明明白白，有的放矢!
雅思听力必知的冷知识点
雅思听力中有很多场景，除了积累这些场景的听力素材外，多拓展一些冷门知识点也是很有必要的。
对中国学生而言，到国外求学除了能开阔眼界，进一步了解当地的文化和风情，更主要的目的仍是精深自己的学术知识。因此，雅思听力不仅涵盖了对生存能力的检测，也涉及到了对学生各方面学术知识理解能力的考察。
在曾经考过的学术场景中，动物学是出现频率较高的一个。仅在近期的几个月里，动物学场景就出现了四次。通过对这些考题的分析，可以发现，动物学场景主要考察的特点为：
陌生的场景单词一些动物学的场景单词对考生而言可能较陌生，例如：
在雅思考试中，考察了非洲鳄鱼(crocodile)的生活情况，谈到了沙漠(desert)和湿地(wetland)中鳄鱼如何生存，还谈到了鳄鱼的栖息地岩洞(cave)和鳄鱼的迁徙途径(migration pattern)以及鳄鱼栖息地植被(vegetation)的情况。
在之前的考试中，考察了几种主要的鲸鱼(whale)，如抹香鲸(sperm whale)，小须鲸(minke whale)，以及这些鲸鱼身体构造的区别。
雅思考试中，谈到了对海洋生物的研究(marine research)以及现在研究的课题是免疫系统(immune system)等。在9月2日的考试中，考察了动物化石(fossil)的形成及保护，出现了像沉淀物(sediment)这样比较专业的词汇。
答案并不陌生虽然出现了较陌生的单词，但多数需要填写的答案并非陌生单词。这个特点不仅仅出现在动物学场景里，在很多学术类的场景里都有体现。这就意味着考生完全不必对这类话题产生过多的恐惧感，也不要因为听到了一些陌生的单词，而中途放弃。只要能够把握住题目所提供的关键信息点，成功做答大多数的题目仍是很有可能的。
如在上述的几次考试中，多数答案为常见词：exhibition(展览)，sunlight(阳光)，insect(昆虫)，procedure (过程)，soil(土壤)，recorder(录音机)，data(数据)，fear(惧怕)，depth(深度)等。
很多学术场景，如课程设置和介绍，学校设施的介绍，商业问题研究，学习方法等，都不仅仅出现在SECTION4也在SECTION3出现过，而动物学场景从以往的题目来看，往往只出现在最后一个部分，以一个人的独白形式出现。
这样一来，考生很有可能在听的过程中，由于对动物学背景知识和某些单词的不熟悉，更难把握节奏，这就要求考生在备考的过程中加大对相关词汇的熟悉度，加强对大段独白语流的练习。
就题型来看，动物学场景主要包括了选择题、填表题和配对题。其中填表题为主导题型，另外两种题型比例较少。这就要求考生在平时仍需注重对单词反应，记录速度和拼写这些方面的练习。
通过上述简要的分析，不难看出动物学场景介绍了一些考生平时很少关注的专业知识，对此，特意提醒雅思考生，要充分的扩展自己英语的学习面和阅读面，充分准备雅思考试，也为将来的深造打下良好的学术基础。
