托福考试如何避免听力拖后腿?补足短板要这么练

练听力做笔记提升记忆效果

在托福听力进行中,材料是只读一遍的,而且在有些题目中,考生只有在材料播放完之后才能看到题目。正因如此,考生在听的过程中做好笔记就成为了一个非常重要的环节。在记录笔记的过程中,大家要做到条理清晰、书写尽量工整、提倡使用一些自己惯用的缩写和图形来表达,提高记笔记的效率,并能够为答题时候高效准确地提取信息打下良好的基础。而只有这样,大家在看到了题目后,才能根据之前所记录的笔记,有条理地分析出最终答案。如果对听力材料的内容理解不是特别充分,或者对可能考查的重点及细节把握不够,都会造成听完材料之后却对题目不知如何着手,这就要求大家在听材料的过程中,除去对材料本身的理解把握及记录之外,还应该注意对话中谈话双方对所谈论内容的观点及态度,从而从整体上感知材料,形成对材料的整体的全面的把握。

合理切换听和写步骤保证节奏

在托福听力备考过程中,听写练习是一个非常重要的环节。而小编建议大家,对于听写练习的开展可以在有了一定听力基础后再正式开始。这么做的原因很简单,听力基础较好的同学可以完全把握好听和写的节奏,在记录“写”的内容时,也可以同时把握好“听”的同步进行,不会有相互博弈的问题产生。很多同学听写中常会自己跟自己打架,顾着听就来不及写,专心写又没听清后面说的内容,结果听也没听懂,记录也乱七八糟自己都看不懂。想要避免这种问题,考生一定要练好听与写之间的平衡和节奏感。

寻找自己的听力弱点盲区来改善

在听力练习完成之后,考生也不能简单地核对答案就觉得万事大吉。大家最好在核对答案的同时做好记录,查看一下自己有没有在同类问题或者相似内容出现反复错误的情况,通过对比发现可能存在的一些薄弱环节和高频盲区,及时调整之后的训练目标,有针对性地迅速搞定弱点问题,让自己的练习能有真正的快速提升。

不标准发音需及时纠正

有些考生可能会觉得,读音和听力有什么关系。实际上,不标准的发音不仅会影响到大家的口语考试,对于听力同样也是有损害的。明明标准发音是那样,考生自身认知的发音却有所差异,到了听力考试中就容易出现明明听到但听不懂的情况。实际上,因为发音问题导致自己听不懂标准考试听力发音的情况并不少见。而托福考试作为一门英语能力综合测试,各个题型之间所需求的英语能力其实也是相互关联的,纠正了读音问题,不仅会直接让各位的口语能力得到提升,也会让听力间接受益。因此,纠正读音问题对于听力来说也是必不可少的。

2020托福听力练习:美国政府拟用无人机发射疫苗保护濒危雪貂

A recent headline on the Web site theverge.com got a lot of attention on social media. Because each new phrase seemed to take the message in an unexpected direction. The headline read: U.S. government plans to use drones to fire vaccine-laced M&Ms near endangered ferrets.

Some background. Black-footed ferrets have been on the endangered species list since 1967. Only about 300 were known to be alive in the wild at the end of 2015. They tend to live in the Great Plains and the West. Because they love to eat prairie dogs, which tend to live in the Great Plains and the West. Unfortunately, prairie dogs often harbor fleas, and fleas can carry the plague. Yup, that plague, the so-called Black Death that killed millions in Europe in the 14th century.

So ferrets suffer when fleas cause a plague outbreak in prairie dogs, either because the ferrets also catch the disease or because the prairie dogs die and the ferrets go hungry. Officials have tried vaccinating individual ferrets and they've tried treating prairie-dog burrows with flea-killer. But neither method is particularly efficient.

And so the U.S. Fish and Wildlife Service is preparing a study for September in the UL Bend National Wildlife Refuge in Montana. The viral headline was incorrect about the M&Ms, but otherwise, yes, aerial drones will shoot vaccine-laced pellets designed to be irresistible to prairie dogs. The drone delivery system should quickly spread the vaccine-carrying goodies over a wide area so that lots of prairie dogs gobble them up—thus making the prairie dogs available to be gobbled up, safely, by the endangered ferrets.

And so everybody wins. Except for the prairie dogs that get eaten. And the Yersinia pestis bacteria that cause plague. Well, that's it for me, I've droned on long enough.

Theverge.com网站最近的一条标题引起很多社交媒体的关注。原因是每一个新短语都好像将这条信息引往了一个意想不到的方向。标题写着:美国政府计划用无人机向濒危雪貂栖息地发射带有疫苗的M&Ms糖果。

背景介绍:黑足雪貂在1967年被列入濒危物种名单。截至2015年底,现存的野生黑足雪貂只有300只左右。黑足雪貂喜欢生活在美国大平原和美国西部地区。这是因为它们喜欢吃的草原犬鼠生活在美国大平原和西部地区。不幸的是,草原犬鼠通常会滋生跳蚤,并且跳蚤可能带有鼠疫。没错,被称为“黑死病”的鼠疫在14世纪导致欧洲数百万人死亡。

因此,当跳蚤导致鼠疫袭击草原犬鼠时,雪貂也会受到牵连,要么是因为雪貂也会染上鼠疫,要么是因为草原犬鼠的死亡导致雪貂挨饿。官员曾尝试给雪貂接种疫苗,也曾尝试往草原犬鼠的洞穴里喷洒杀蚤剂。但这两种方法都不是特别有效。

所以,美国鱼类和野生动物局正在为一项研究做准备,该研究将于9月在蒙大拿州国家野生动物保护区启动。那条轰动标题中有关M&Ms的部分是不正确的,不过除此以外,无人机的确将发射带有疫苗的糖果,这种糖果被设计成使草原犬鼠无法抗拒的美味。无人机输送系统应在广泛区域迅速播撒带有疫苗的糖果,让大量草原犬鼠食用,进而让濒危雪貂可以安全地捕食草原犬鼠。

这样大家都是赢家。当然,除了被吃掉的草原犬鼠和引发鼠疫的鼠疫耶尔森氏杆菌。好了,就是这些了,我已经讲了很长时间了。

重点讲解:

1. either...or... (表示在两者或多者中择其一)或者,要么;

例句:Either we will find a supply, or we will make the goods.

我们或是寻求供货,或者自己制造。

2. go hungry 挨饿;吃不饱;

例句:Leonidas' family had been poor, he went hungry for years.

利奥尼达斯家曾经很穷,他有很多年都吃不饱肚子。

3. gobble up 贪婪地吃;狼吞虎咽;

例句:There were dangerous beasts in the river that might gobble you up.

河里有吃人的危险动物。

4. except for 除了;除…之外;唯有;

例句:Smith is a good man, except for his bad temper.

史密斯除了脾气不好外,是个好人。

5. drone on (人)絮絮叨叨地说,喋喋不休地说;

例句:Aunt Maimie's voice droned on.

梅米姨妈喋喋不休地说着。

2020托福听力练习:鸡味可驱蚊防疟疾

In Africa's battle against malaria, two low-tech tactics—insecticides and bed nets—have done a decent job killing off mosquitoes. "But it's mainly one species that's been affected. That's a species called Anopheles gambiae, often referred to the African malaria mosquito." Rickard Ignell, a chemical ecologist at the Swedish University of Agricultural Sciences.

He says, despite that success, the problem is far from solved. For one, mosquitoes are developing resistance to insecticides. And two, there are many other species that can spread the disease. Including one that's common in the horn of Africa: Anopheles arabiensis.

Unlike the pickier gambiae, its palate is wide-ranging. Arabiensis sucks the blood of cattle, sheep, goats. But… not chickens. "Chickens like mosquitoes. So they'll actively feed on mosquitoes and other insects. So avoiding chickens could be a way of surviving, and evolving a way of smelling the chickens could be an early warning system for them."

And it turns out, that aversion to chickens can be used against the insects. Ignell and his colleagues isolated chemical compounds from chicken feathers, and dispensed them next to a human sleeping under a bed net—a human lure. And they found that fewer mosquitoes came round for a snack, due to the repellent chemicals. The findings appear in the Malaria Journal.

Ignell says this chicken cologne won't be immediately available. "Ideally the world would be like that, that we could bottle it up and send it off and they don't have to pay anything. But that's not the case usually." Luckily, there's an equally effective substitute. "We can actually reduce the number of mosquitoes indoors by just using a chicken. So that's probably the cheapest option."

非洲在对抗疟疾时用了两种低科技手段:杀虫剂和蚊帐,这两种方法有效地杀死了蚊子。“但是,这两种方法只能对一个物种产生影响。这个物种是冈比亚按蚊,常被称为非洲疟蚊。”瑞典农业科学大学的化学生态学家理查德·伊格内尔说道。

他表示,虽然这两种方法取得了成功,但问题远远没有解决。一方面,蚊子已经对杀虫剂产生了抗药性。另一方面,还有很多其它物种可以传播疾病。其中一个物种就是在非洲之角这一地区常见的阿拉伯按蚊。

与更为挑剔的冈比亚按蚊不同,阿拉伯按蚊的口味更为广泛。阿拉伯按蚊会吸牛、绵羊、山羊的血,但是……却不会吸鸡的血。“首先,鸡喜欢蚊子。所以它们会以蚊子和其他昆虫为食。因此,对蚊子来说,不吸鸡的血可能是一种生存方式,而使闻鸡类味道的能力得到进化可以成为早期预警系统。”

事实证明,可以利用这种对鸡类的厌恶感来对抗昆虫。伊格内尔和同事从鸡的羽毛中分离出化合物,然后将这种化合物放置在睡在蚊帐里的人类的旁边,这是一种人为诱惑。他们发现,由于讨厌这种化学物质,很少有蚊子会进入蚊帐吸血。这项研究结果发表在《疟疾杂志》上。

伊格内尔表示,现在还不能马上提供这种鸡味古龙香水。“最理想的情况是,我们可以把它装进瓶子里,然后让味道散发出去,它们不需要付出什么。但是显然情况并非如此。”幸运的是,有一个同样有效的替代品,“我们可以用一只鸡来减少室内蚊子的数量。可能这是最便宜的选择。”

重点讲解:

kill off 被全部杀死;被灭绝;

例句:Their natural predators have been killed off.

它们的天敌被全部杀死。

2. be far from 根本不;远远不;

例句:His explanation was far from satisfactory.

他的解释一点也不令人满意。

3. turn out 结果发现;结果是;

例句:It turned out to be a wild-goose chase.

结果证明这只不过是一场徒劳。

4. due to 由于;因为;

例句:Accidents due to driving at high speed were very common that weekend.

在那个周末因高速驾驶造成的交通事故很多。
