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中通过变速听音频素材来训练的做法并不少见，今日 我给大家带来了托福听力备考慢速英语练习方法技巧讲解，盼望能够 关心到大家，下面我就和大家共享，来观赏一下吧。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 已经超过了很多，更何况要预备托福听力考试的同学。而慢速播放下 假如还听不懂，那么

2、唯一缘由就肯定不是生词的问题，只能是考生对 这个单词的发音极其生疏，大脑根本没有反映。假如让考生看一看原 文，考生会不屑一顾的。但在听的时候却不知所云。慢速训练提升发音精确性接下来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，考生都能精确 的复述出来，包括每一个单词。这里在语音上不是很好的伴侣要留意 了，由于是慢速英语，所以只要考生有正常的听力力量再加上肯定的 毅力，就完全可以把自己的发音仿照的和播音员没什么两样。发音是 一个人的英语门面。假如考生根据这样的方法专心练习，不出一两个2. cool off （使）变凉；（使）凉快下来；例句：May

3、be hes trying to cool off out there in the rain.可能他是想在雨里凉快一下。3. soak up 汲取；例句：The cells will promptly start to soak up moisture.细胞会马上开头汲取水分。4. on average平均起来；按平均值；例句：On average, Mr. Kelly works out four days a week for at least an hour at a time.凯利平均每周熬炼四天，每次至少熬炼一个小时。5. result in导致；引起；造成；例句：His care

4、lessness results in a serious blunder.他的粗枝大叶导致他犯了一个严峻错误。6. a close shave幸免于难;侥幸脱险；例句：His life is no longer in danger, but it was a close shave.他不再有生命危急了，但那真是死里逃命。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仿照发音天赋都是很好的，任凭叫出一名 高校四级通过的高校生，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。其实我们中国同学在口语和听力上 缺陷主要有两个缘由：一是缺乏练习。这也是

5、传统教学方法的圆满。 也是这种只注意书面的分析英语的受害者。二是缺乏士气。老是可怕 自己会说错，可怕丢脸。除非你是在国外长大，英语就是母语，你可 以骄傲的说:我就是说错了那也是对的，由于英语是我的母语。而托 福考生把英语作为其次语言的学习是不行能不犯错误的，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 已听懂了这段文章。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，过一段时间后信任大家就会开头适应并喜爱上托福的 听力考试题了。2022托福听力练习：人类是超级捕食者Small carnivores一like foxes or raccoons

6、or badgers一are themselves prey for larger predators一like wolves. So they spend time hiding instead of hunting. This influence that big predators have on their ecosystem is called a landscape of fear. But humans are wiping out most of the worlds big predators.Which you might assume is good news for t

7、he small ones.But some researchers think that humans exert our own landscape of fear. Those foxes, raccoons and badgers just keep on hiding一only now, theyre hiding from us. In reality, the situation may be far worse.Humans kill these smaller carnivores, so things like raccoons and foxes that we have

8、 here in North America, European badgers that they have in the U. K. and elsewhere in Europe, and we kill them at a rate thats four times greater than their conventional large carnivore predators.Liana Zanette of Western University in London, Ontario.Because our killing of these smaller carnivores i

9、s kind of off the scale, were considered the superpredator.To see how humans have altered the landscape of fear, Zanette and her team traveled to a small forest thats home to lots of European badgers near Oxford in the U. K. They used hidden speakers to broadcast the sounds of bears and wolves一two h

10、istoric predators, both of which are no longer a threat. They also played the sounds of sheep, dogs and people. Hidden cameras recorded the badgers willingness to look for food outside of their burrows as those sounds were played.They discovered that the badgers have retained some of their fear of b

11、ear sounds, and know that dogs still pose a threat.But theyve lost their fear of wolves.They treated the wolf calls just like the sheep calls.Despite their fear of bears and dogs, the badgers still eventually went out to eat amid their sounds. But when they heard people they would not emerge from th

12、eir burrows at all until the human sounds were completely off. So they would cower in their burrows for the two hours that the sounds were on, waiting for those human sounds to go off.In other words, they were leery of bears but were downright terrified of us. The findings are in the journal Behavio

13、ral Ecology.The badgers recognize who their enemies are. . . they have recognized humans as their principle threat.狐狸、浣熊、獴等小型食肉动物是狼等较大食肉动物的猎物。所以 它们大部分时间在隐藏而不是捕猎。这种大型捕食者对小型动物生态 系统的影响被称为“恐惊景观”。不过人类正在毁灭世界上大部分 大型捕食动物。你可能会认为这对小型食肉动物来说是个好消息。但是一些讨论人员认为，人类正在施加我们自己的“恐惊景观”的 作用。导致狐狸，浣熊和獴连续保持隐藏的状态，虽然现在它们只是 躲着我们

14、。但实际上，状况可能会更糟。“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衡人类对它们的猎杀率比它们传统意义上 的天敌一一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高校。“由于我们人类对这些小型动物的猎杀属于超标状况，所以人类应 当被视为超级捕食者。”为了查明人类是如何转变这种“恐惊景观”的，詹尼特和她的团队 前往英国牛津郡四周的一个小森林，那里是大量欧洲推的栖息地。他 们使用隐蔽的扬声器播放熊和狼的声音，这两种曾经的捕食者现在已 经不再构成威逼了。他们还播放了绵羊、犬类和人类的声音。隐蔽摄 像机对灌在听到这些声音时是否情愿出洞觅食

15、的状况进行了记录。他们发觉，灌对熊仍有一些恐惊，而且它们知道狗也对他们构成威 逼。不过它们已经不再可怕狼。“它们对狼叫的反应和听到羊叫差不多。”虽然獴仍旧可怕熊和狗，但是它们最终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逝 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 们可能会躲在洞里颤抖，等待人类的声音消逝。”换言之，獴对熊保持警觉，但是对我们人类则是彻底的恐惊。这一 讨论结果发表在行为生态学期刊上。“推认出了谁是它们的敌人它们把人类当作它们的主要威逼。”重点讲解：1. wipe out摧毁；毁灭;使灭亡；例句：Some animal

16、s have been wiped out through ignorance.有些动物由于人们的无知而灭亡了。2. in reality事实上；实际上；彳列句：The house looks very old, but in reality its quite new. 这房子看起来很旧，实际上很新。3. in other words换言之;换句话说;也就是说； 例句：In other words, she must give up singing. 换言之，她必需放弃唱歌。4. be leery of猜疑的；警觉的;有戒心的；例句：I tend to be a bit leery of c

17、ut-price bargains.我对减价商品有点戒心。2022托福听力练习：皮肤变色有助气候掌握与沟通Various animals evolved coloration that keeps them hidden.A jaguars patterns help it slink undetected across the sun-dappled rainforest floor. The mottled pigmentation on the wings of some let them rest on tree bark undisturbed. And then there are

18、 animals that can quickly change their appearance一for example, the Central Bearded Dragon.This two-foot-long lizard lives in the more arid parts of Australia.They can change color really quickly, just in a matter of seconds or minutes.University of Melbourne biologist Katie Smith.And they do this by

19、 moving pigments within specialized skin cells called chromatophores.Bearded dragons modify their colors for camouflage, or to maintain their body temperature, or to communicate with other dragons. Smith wanted to know how they meet all those needs with the same tool kit.So she and her team rounded

20、up twelve bearded dragons and put them through a series of tests before releasing them back into the wild. They found that when the dragons want to communicate with other members of their species, they change the colors on their neck.This is actually one of the reasons theyre called bearded dragons一

21、because they look like they have a really serious five oclock shadow.Changes to their backs were for temperature regulation. Shifting to yellow lets them to cool off during extreme heat, while darker greys allow them to soak up more heat during cooler weather.They actually save about, on average, 22

22、 minutes a day at the darker colors than the lighter colors. Thats about 85 hours throughout the whole year.Eighty-five hours a year NOT spent out in the open and exposed to potential predators. The results were published in the Proceedings of the Royal Society: B.The lizards can clearly control eac

23、h part of their body separately, resulting in an efficient system. Temperature regulation involves the back, which is facing the sun. Social signaling uses the neck, easily visible to another lizard theyre faced off with.The researchers next task is to see what happens when the lizards have to deal

24、with simultaneous but conflicting coloration requirements一situations that could give a bearded dragon a close shave.许多动物会进化颜色让自己隐蔽起来。美洲豹身上的斑纹让它可以 在阳光斑驳的雨林地带潜行。一些动物翅膀上的斑驳镇静色素可以让 它们在树上休息时不被打搅。另外，还有些动物可以快速转变它们的 外表，比如鬃狮蜥。这种两英尺长的蜥蜴生活在澳大利亚的干旱地区。“它们可以特别快速地转变颜色，仅仅只需要几秒钟或者几分钟的 时间。”凯蒂史密斯是墨尔本高校的生物学家。“它们通过转移特定皮

25、肤内细胞内的色素来实现的。”鬃狮蜥通过转变自己的颜色进行伪装、保持体温，或和其他鬃狮蜥 进行沟通。史密斯想知道拥有同样爱护伪装的鬃狮蜥是如何满意这些 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。他们发觉，当鬃狮蜥想和本物种的其 他成员进行沟通时，它们会转变自己颈部的颜色。“这实际上是它们被称为长鬃狮蜥的缘由之一，由于它们看起来像 长了胡须。”鬃狮蜥转变背部的颜色是为了调整温度。变成黄色可以让它们在酷 热的天气中凉快下来，而变成深灰色可以让鬃狮蜥在寒冷的天气汲取 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。

26、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。这项讨论结果发表在皇家学会学报B上。鬃狮蜥可以明确地掌握自身各个部分，从而形成一个有效的系统。 在有阳光时，可以调整背部的颜色。社交的时候调整颈部的颜色，让 另一只鬃狮蜥清晰地看到它们面临的状况。讨论人员的下一个任务是观看鬃狮蜥在处理同时发生又相相互冲 突的变色要求时会有什么状况发生，那可能是让它们死里逃命的状况。重点讲解：1. round up使聚集;使聚集；例句：He had sought work as a cowboy, rounding up cattle.他找了一份放牛的差事，负责把牛赶到一起。
