托福考试如何避免听力拖后腿怎么办

1、托福考试如何避免听力拖后腿怎么办 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

2、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。

3、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

4、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：加固水坝有利鱼类繁殖in the early 19th century the fur industry reached what was then known as the oregon territories. lewis and clark found massive numbers of paci

13、复方法以恢复esa名单上的物种，但我们真的不知道哪种方法有效，哪种方法没有作用。”这是环境咨询公司生态研究公司和犹他州立大学的研究人员尼克鲍威斯所说。他说，美国每年在恢复流域方面花费10亿美元，但是没有任何实证信息来指导这些努力。所以鲍威斯和他的团队测试了通过帮助海狸来帮助鱼类的办法。大坝可以自然地改变河流的流动，为鱼类提供各种合适的栖息地。但由于水域质量严重下降，导致没有足够的木本植物供海狸建造坚固的水坝。只要有大风暴来袭，它们建造的劣质水坝就会被冲走。“我们的想法是，能不能通过加强这些水坝使它们在高流动性期间保持完整性，由海狸采集沉积物去填补洪泛区来保持完整性?”七年来，研究者将有过很多人

14、工加固水坝经历的bridge creek与没有人工加固水坝经历的murderers creek,相比较。虽然有观点认为海狸水坝对鱼类有害，不过在bridge creek，鱼类大量繁殖起来。这项研究成果刊登在科学杂志上。“海狸非常擅长扰乱系统，而这种干扰正是我们所需要的，因为这样能创造出更多复合鱼类栖息地。”与传统修复方法相比，每公里河流只需花费1.1万美元的人工加固大坝更加便宜，因为海狸为我们做了大部分工作。这是一桩相当划算的交易。重点讲解：1. kill off 全部杀死;灭绝;例句：his spray will kill off any pests or insects.这种喷雾能够消灭任
