1、如何理性看待托福阅读机经 托福阅读备考中很多同学都会去网上找机经，不得不说，机经确实是备考环节非常重要的资料之一，但是大家不要盲目使用。托福阅读机经如何正确使用呢?下面就和大家分享托福阅读机经怎么用，来欣赏一下吧。托福阅读机经怎么用?理性看待机经一.托福阅读机经有多大价值?关于托福阅读机经价值这一点，如果大家找过比较多的机经就能发现一些端倪。实际上很多*渠道不太靠谱的所谓真题机经都存在一些质量方面的问题。这是因为很多托福阅读真题是靠考完试的同学回忆整理得来的，而这些回忆托福阅读真题的考生本身的水平就参差不齐，回忆的内容不完整或者出现疏漏甚至错误的情况比比皆是，他们给出的答案自然正确率也无法保证

2、。而即便是答案全对，在托福考试本身相当紧张的时间流程压力下，这些考生也难免会出现回忆中漏题或记错题等等问题，这就让这些托福阅读真题机经的准确性值得商榷了。二.托福阅读机经不要背记答案除了考后回忆出的机经存在质量问题外，还有一点也让托福阅读真题机经的价值受到质疑，这就是所谓的变体题现象。具体来说，ETS其实对于大家会在考后回忆整理真题的情况并非完全不知情，而其应对方法也非常简单，那就是更改题目，背过托福阅读真题的考生可能会发现，每次考试即便阅读*还是旧的*，但出现的题目却并不是完全一样的。也就是说，ETS的托福阅读题库中，对于每一篇*并不是只有12-14道固定的题目。因为每名考生在2次考试中遇到

3、同一篇考试的概率不大，所以大家会觉得*都是重复的。但其实每次的考题常会有所出入。这些题目就是所谓的变体题。特别是托福阅读真题中的词汇题、插入句子题、简化句子题等都是很容易进行改动的。而哪怕是稍微复杂一些的细节题和要点总结题，选项也是可以很容易改变的。三.不要太过依赖托福阅读机经很多考生对于托福阅读真题机经有着盲目的新人，觉得准备托福阅读时狂练真题就够了，认为背了真题考试时就可以万事大吉。甚至有些同学的托福阅读备考方式就是背真题、看真题，把机经当成最有效的提分法宝。这种过于极端的做法无疑是错误的。托福考试考得不是记忆力而是语言能力，因此托福阅读真题机经能够带给大家的帮助其实也是有限的，是建立在考

4、生本身具备足够的阅读能力才能体现出实际价值的。因此，小站君建议大家在准备托福阅读时别太过于迷信机经，不要认为背了真题机经考试时问题就能迎刃而解，请从心态上就摆脱对托福阅读真题机经的依赖。从2020年开始，托福考试每个考场会出现两套以上的不同考题，所以托福阅读考试的变数越来越大，即便是机经也很难准确预测。大家一定要理性看待托福阅读机经，不要过分依赖机经。打好基础，提高做题能力才是关键!托福阅读真题原题+题目There are only a few clues in the rock record about climate in the Proterozoic eon. Much of our

5、information about climate in the more recent periods of geologic history comes from the fossil record, because we have a reasonably good understanding of the types of environment in which many fossil organisms flourished. The scarce fossils of the Proterozoic, mostly single-celled bacteria, provide

6、little evidence in this regard. However, the rocks themselves do include the earliest evidence for glaciation, probably a global ice age.The inference that some types of sedimentary rocks are the result of glacial activity is based on the principle of uniformitarianism, which posits that natural pro

7、cesses now at work on and within the Earth operated in the same manner in the distant past. The deposits associated with present-day glaciers have been well studied, and some of their characteristics are quite distinctive. In 2.3-billion-year-old rocks in Canada near Lake Huron (dating from the earl

8、y part of the Proterozoic age), there are thin laminae of fine-grained sediments that resemble varves, the annual layers of sediment deposited in glacial lakes. Typically, present-day varves show two-layered annual cycle, one layer corresponding to the rapid ice melting and sediment transport of the

9、 summer season, and the other, finer-grained, layer corresponding to slower winter deposition. Although it is not easy to discern such details in the Proterozoic examples, they are almost certainly glacial varves. These fine-grained, layered sediments even contain occasional large pebbles or dropsto

10、nes, a characteristic feature of glacial environments where coarse material is sometimes carried on floating ice and dropped far from its source, into otherwise very fine grained sediment. Glacial sediments of about the same age as those in Canada have been found in other parts of North America and

11、in Africa, India, and Europe. This indicates that the glaciation was global, and that for a period of time in the early Proterozoic the Earth was gripped in an ice age.Following the early Proterozoic glaciation, however, the climate appears to have been fairly benign for a very long time. There is n

12、o evidence for glaciation for the next 1.5 billion years or so. Then, suddenly, the rock record indicates a series of glacial episodes between about 850 and 600 million year ago, near the end of the Proterozoic eon.1. Which of the following does the passage mainly discuss?(A) How patterns in rock la

13、yers have been used to construct theories about the climate of theProterozoic age(B) What some rare fossils indicate about glacial conditions during the late Proterozoic age(C) The varying characteristics of Proterozoic glacial varves in different parts of the world(D) The number of glacial episodes

14、 that the Earth has experienced since the Proterozoic age2. According to the passage , the fossil record of the Proterozoic eon is(A) highly regarded because it preserves the remains of many kinds of organisms(B) less informative than the fossil record of more recent periods(C) very difficult to int

It can be inferred from the passage that the principle of uniformitarianism indicates that(A) similar c

The word resemble in line 14 is closest in meaning to(A) res

According to the passage , the layers in varves are primarily formed by(A) fossilized bacteria(B) pieces of ancient dropstones(C) a combination of ancient and recent sediments(D) annual cycles of sediment transport and deposition7.

18、 The phrase the other in line 17 refers to another(A) annual cycle(B) glacial lake(C) layer of sediment(D) season8. According to the passage , the presence of dropstones indicates that(A) the glacial environment has been unusually servere(B) the fine-grained sediment has built up very slowly(C) ther

Why does the author mention Canada, North America, Africa, India, and Europe in lines 23-24?(A) To demonstrate the global spread of dropstones(B) To explain the principles of varve formation(C) To provide evidence
