托福听力出题带你该如何辨别呢

1、第 PAGE12 页 共 NUMPAGES12 页托福听力出题带你该如何区分呢托福听力出题你该如何区分呢?首先是做托福笔记的方法：我个人的习惯差不多每个段子都能写一面纸。这里确实有很多内容是无用的，但假如遇到口音重、句子构造复杂的文章，一边记一边听有困难，我就会放弃大量笔记，只写【关键词】：p 。在完全不知道题目在问什么的时候，根据一个词儿定位，再回忆原文，可能会有一定的帮助。至于Lecture，一般我会用线条把草稿纸分割成“田”或 “用”字的款式，写下【关键词】：p 以后，假如教授说：我讲的这个东西啊，有三个类别/三个开展阶段/三个解决方式，就在“用”字纸张上写，左边每一格写关键分类 词，右

2、边对应格儿写特点和评价。有例子、学生提问、奇怪语气的地方打上标记。这种情况下一般能网罗一半以上的题目。 顺便说一句，我觉得这个笔记方法对于口语来说也是适用的，我口语不算高只有26，但后四题都是good，不得不说笔记功绩大大的。记笔记的同时要判断出题点。很多人都说出题点可以预见，我个人也觉得托福听力至少有50%的题目在听的时候就能判断了，这局部的分数要拿稳。第一是主题题。这啥也不用说了，必考，这样一来，6道题搞定了。第二是奇怪语气。这个也很好判断，我个人觉得有：“结巴和长停顿”，“打断别人说话”、“夸大的发音和语气的”等。第三是我自己的感觉。假如是总分-列举型的文章，最后一个列举考到可能性非常大

3、。所以假如前两个都没听明白，别放弃，因为最后可能出题的是最后一个。即使考不到最后一个，考了很难的“特点匹配”的好几分的题目，你至少可以用最后一个分类的特点来排除。所以最后一个一定要认真听。2022托福听力练习：地衣含有三种以上成分Lichens.

4、 they say, when “Alice Algae,” took a “lichen” to “Freddie Fungus.”But that simple description covered up a larger mystery: how could two different lichen species bine the same building blockssame fungus, same algae“and yet they look very different, have very different chemistry, and some of them ev

Same underlying parts, different color and chemistry. They ground the lichens up, a

6、nd then analyzed their RNA. What they expected to find was two genomes: one fungus, one alga. “And what we found is that, at the end of a lot of analysis, we had was three genomes, not two.And this was really surprising.”The third genome was from a type of yeast. And the more yeast was present, the

7、more yellowishand more toxicthe lichen was. The study appears in the journal Science.But how could scientists spend so many years studying these lichensand still miss this crucial third species? Spribille says it could have been the type of geic sequencing. Previous studies relied on DNA barcodes, w

Sort of like identifying the occupants of a pletely dark room by shouting out a few names and seeing who answers.What Spribille did, instead, was just turn all the lights on, with whole genome sequencing, revealing the ide

9、ntity of all occupants, and in doing so, “we eliminated anything that required going in and calling out somebodys name so to speak.”As for whether some lichens might have four, five species? “I certainly wouldnt rule it out at this point.” Because this study indicates lichens are truly more than the

10、 sum of their parts. Including, of course, the parts we still dont know about.地衣可能是两种生物以共生关系存在的最常见例子。地衣由1种真菌和1种光合生物(如藻类)组成。这种联络是固有的，就像他们说的，“爱丽丝藻类”和“弗雷迪真菌”共生形成地衣。但是这种简单的描绘掩盖了一个更深奥的机密：两种不同的地衣物种如何结合同样的成分即同样的真菌和同样的藻类，“而且，它们看上去非常不同，它们的化学成分也不同，有些地衣甚至有着明显不同的生态。”托比斯普利比尔是蒙大拿大学和奥地利格拉茨大学的进化生物学家。他和同事对符合上述条件的两种地

11、衣进展了研究。这两种地衣的根本成分一样，但颜色和化学成分不同。他们将地衣磨碎，然后分析p 了它们的核糖核酸。他们原以为会发现两个基因组：一个是真菌，另一个是藻类。“但最后，在进展大量分析p 以后，我们发现的是三个基因组，而不是两个。这真是太让人惊讶了。”第三个基因组来自于一种酵母。酵母的含量越多，地衣颜色越黄，毒性也越强。这项研究发表在科学杂志上。但是，科学家们怎么会在研究地衣多年后仍未发现这至关重要的第三物种?斯普利比尔表示，可能是由于基因测序的方法不一样。此前的研究依赖于DNA条形码，只是对这一基因组中的一局部进展抽样调查，用以确认潜在的真菌和藻类。这就好似在一间完全黑暗的房间里，通过喊出

12、几个名字，看看谁作出答复，来确定居住者身份。而斯普利比尔的做法是，翻开房间内所有的灯，通过全基因组测序来提醒所有居住者的身份，并且通过这种方法，“可以说，我们不需要进入房间喊出某人的名字。”至于是否有地衣含有第四或第五种成分?“如今我不能完全排除这一可能性。”因为这项研究说明，地衣不仅仅是各局部的单纯相加。还包括我们目前尚不知道的成分。重点讲解：1. cover up 隐藏，遮掩(事实例句：He suspects theres a conspiracy to cover up the crime.他疑心有人密谋掩盖犯罪事实。2. grind up 磨碎;碾碎;将磨成粉;例句：We grind

14、 speak 可以说;可谓;例句：But for young people it presents an opportunity to follow the sun, so to speak.但对年轻人来说，却可以说是追寻生活乐趣的良机。7. rule out 排除;不予考虑;例句：I think we can rule out the possibility of objection to us.我认为我们可以排除有人反对我们的可能性。2022托福听力练习：选民不会背竞选演讲所影响Donald Trump hasnt been running the most traditional cai

20、 Id be providing advice as to how one ports oneself with the national press, try to earn some goodwill. I guess just being polite. I would say that Trumps sort of lethargic process of caigning is probably the least of his worries.” Better, he says, to just spend more time fundraising. To throw more

Then agains free.唐纳德特朗普没有用最传统的竞选方法组织竞选活动。这并不是仅指他未经过滤的推文。“他完全无视了这是总统竞选演讲。”托马斯伍德是俄亥俄州立大学政治学的助理教授。“特朗普的公共活动只有其对手的一半。”伍德曾在2022年跟随罗姆尼和瑞安的竞选团队进展竞选活动。当时，竞选团队每天晚上都要调查数千名选民，调查人数可能高达6.4万人，在政治家走访当地后询问选民对他们的看法。前提是选民知道当地的竞选活动。“某位候选人没有前往彭萨科拉的某个地方，而是去到当地的市场。对许多人来说，去哪里访问都一样，因为竞选活动看起来差不多。这些活动会互相交融。对正在看晚间新闻的人来说，很难弄清楚新闻里的人正在当地市场进展访问。”换言之，对大多数当地人或是临近市场的大多数居民
