托福听力备考慢速英语练习方法技巧讲解

1、托福听力备考慢速英语练习方法技巧讲解 托福听力备考慢速英语练习方法技巧讲解托福听力慢速英语训练方法分析考生由于方法的失策，造成把大量的时间精力投入其中，可是回报却难以和付出平衡，收效甚微。从慢速英语入手是真正科学的听力突破方法。下载相关的听力资料后，用播放软件进行慢速播放，慢速英语的单词量是1500到2000，也就是说一个比较好的高中生的单词量已经超过了许多，更何况要准备托福听力考试的同学。而慢速播放下如果还听不懂，那么唯一原因就绝对不是生词的问题，只能是考生对这个单词的发音极其陌生，大脑根本没有反映。如果让考生看一看原文，考生会不屑一顾的。但在听的时候却不知所云。慢速训练提升发音准确性接下来

2、要做的就是要保证这一段录音考生是完完全全的听懂了。什么是完完全全的听懂了呢?就是每听完一句话，考生都能准确的复述出来，包括每一个单词。这里在语音上不是很好的朋友要注意了，由于是慢速英语，所以只要考生有正常的听力能力再加上一定的毅力，就完全可以把自己的发音模仿的和播音员没什么两样。发音是一个人的英语门面。如果考生按照这样的方法用心练习，不出一两个月，你的发音就会有长足的进步。中国考生需正视口语问题其实我们大多数中国人的模仿发音天赋都是很好的，随便叫出一名大学四级通过的大学生，发音就要比我所见到的意大利人，日本人，菲律宾人的发音不知要好多少倍。其实我们中国学生在口语和听力上缺陷主要有两个原因:一是

3、缺乏练习。这也是传统教学方法的遗憾。也是这种只注重书面的分析英语的受害者。二是缺乏勇气。老是害怕自己会说错，害怕丢脸。除非你是在国外长大，英语就是母语，你可以自豪的说:我就是说错了那也是对的，因为英语是我的母语。而托福考生把英语作为第二语言的学习是不可能不犯错误的，多犯错误是为了少犯错误。这样一句一句直到把每一句话完全吃掉，已经基本上可以保证考生已听懂了这段*。把这种方法推广到考生之后的托福听力真题中，加上勤加练习，过一段时间后相信大家就会开始适应并喜欢上托福的听力考试题了。2020托福听力练习：人类是超级捕食者small carnivoreslike foxes or raccoons or

12、人类猎杀这些小型食肉动物，所以像北美洲的浣熊和狐狸以及英国和欧洲其他地方的欧洲獾，人类对它们的猎杀率比它们传统意义上的天敌大型食肉动物对它们的猎杀率要高4倍。”利亚纳詹尼特来自安大略省伦敦西大学。“因为我们人类对这些小型动物的猎杀属于超标情况，所以人类应该被视为超级捕食者。”为了查明人类是如何改变这种“恐惧景观”的，詹尼特和她的团队前往英国牛津郡附近的一个小森林，那里是大量欧洲獾的栖息地。他们使用隐藏的扬声器播放熊和狼的声音，这两种曾经的捕食者现在已经不再构成威胁了。他们还播放了绵羊、犬类和人类的声音。隐藏摄像机对獾在听到这些声音时是否愿意出洞觅食的情况进行了记录。他们发现，獾对熊仍有一些恐惧

13、，而且它们知道狗也对他们构成威胁。不过它们已经不再害怕狼。“它们对狼叫的反应和听到羊叫差不多。”虽然獾仍然害怕熊和狗，但是它们最后还是在这些动物的叫声中外出觅食。但是当它们听到人类的声音时，“直到人类的声音完全消失以后，它们才肯从洞里出来。所以在人类声音播放的两个小时里，它们可能会躲在洞里发抖，等待人类的声音消失。”换言之，獾对熊保持警觉，但是对我们人类则是彻底的恐惧。这一研究结果发表在行为生态学期刊上。“獾认出了谁是它们的敌人它们把人类当作它们的主要威胁。”重点讲解：1. wipe out 摧毁;毁灭;使灭绝;例句：some animals have been wiped out throu

23、温，或和其他鬃狮蜥进行交流。史密斯想知道拥有同样保护伪装的鬃狮蜥是如何满足这些需求的。所以，她和自己的团队找了十二只鬃狮蜥，对它们进行了一系列的测试，然后再把它们放回野外。他们发现，当鬃狮蜥想和本物种的其他成员进行交流时，它们会改变自己颈部的颜色。“这实际上是它们被称为长鬃狮蜥的原因之一，因为它们看起来像长了胡须。”鬃狮蜥改变背部的颜色是为了调节温度。变成黄色可以让它们在酷热的天气中凉爽下来，而变成深灰色可以让鬃狮蜥在寒冷的天气吸收更多的热量。“实际上平均而言，它们每天呈现深颜色的时间要比浅颜色的时间少22分钟。那么一年也就长达85个小时。”这也就意味着它们一年有85个小时的时间没有在户外，而且不会接触到可能的捕食者。这
