如何理性看待托福閱讀機(jī)經(jīng)

托福閱讀備考中很多同學(xué)都會(huì)去網(wǎng)上找機(jī)經(jīng)，不得不說，機(jī)經(jīng)確實(shí)是備考環(huán)節(jié)非常重要的資料之一，但是大家不要盲目使用。托福閱讀機(jī)經(jīng)如何正確使用呢?下面小編就和大家分享托福閱讀機(jī)經(jīng)怎么用，來欣賞一下吧。

托福閱讀機(jī)經(jīng)怎么用?理性看待機(jī)經(jīng)

一.托福閱讀機(jī)經(jīng)有多大價(jià)值?

關(guān)于托福閱讀機(jī)經(jīng)價(jià)值這一點(diǎn)，如果大家找過比較多的機(jī)經(jīng)就能發(fā)現(xiàn)一些端倪。實(shí)際上很多來源渠道不太靠譜的所謂真題機(jī)經(jīng)都存在一些質(zhì)量方面的問題。這是因?yàn)楹芏嗤懈ｉ喿x真題是靠考完試的同學(xué)回憶整理得來的，而這些回憶托福閱讀真題的考生本身的水平就參差不齊，回憶的內(nèi)容不完整或者出現(xiàn)疏漏甚至錯(cuò)誤的情況比比皆是，他們給出的答案自然正確率也無法保證。而即便是答案全對，在托?？荚嚤旧硐喈?dāng)緊張的時(shí)間流程壓力下，這些考生也難免會(huì)出現(xiàn)回憶中漏題或記錯(cuò)題等等問題，這就讓這些托福閱讀真題機(jī)經(jīng)的準(zhǔn)確性值得商榷了。

二.托福閱讀機(jī)經(jīng)不要背記答案

除了考后回憶出的機(jī)經(jīng)存在質(zhì)量問題外，還有一點(diǎn)也讓托福閱讀真題機(jī)經(jīng)的價(jià)值受到質(zhì)疑，這就是所謂的變體題現(xiàn)象。具體來說，ETS其實(shí)對于大家會(huì)在考后回憶整理真題的情況并非完全不知情，而其應(yīng)對方法也非常簡單，那就是更改題目，背過托福閱讀真題的考生可能會(huì)發(fā)現(xiàn)，每次考試即便閱讀文章還是舊的文章，但出現(xiàn)的題目卻并不是完全一樣的。也就是說，ETS的托福閱讀題庫中，對于每一篇文章并不是只有12-14道固定的題目。因?yàn)槊棵忌?次考試中遇到同一篇考試的概率不大，所以大家會(huì)覺得文章都是重復(fù)的。但其實(shí)每次的考題常會(huì)有所出入。這些題目就是所謂的變體題。特別是托福閱讀真題中的詞匯題、插入句子題、簡化句子題等都是很容易進(jìn)行改動(dòng)的。而哪怕是稍微復(fù)雜一些的細(xì)節(jié)題和要點(diǎn)總結(jié)題，選項(xiàng)也是可以很容易改變的。

三.不要太過依賴托福閱讀機(jī)經(jīng)

很多考生對于托福閱讀真題機(jī)經(jīng)有著盲目的新人，覺得準(zhǔn)備托福閱讀時(shí)狂練真題就夠了，認(rèn)為背了真題考試時(shí)就可以萬事大吉。甚至有些同學(xué)的托福閱讀備考方式就是背真題、看真題，把機(jī)經(jīng)當(dāng)成最有效的提分法寶。這種過于極端的做法無疑是錯(cuò)誤的。托?？荚嚳嫉貌皇怯洃浟Χ钦Z言能力，因此托福閱讀真題機(jī)經(jīng)能夠帶給大家的幫助其實(shí)也是有限的，是建立在考生本身具備足夠的閱讀能力才能體現(xiàn)出實(shí)際價(jià)值的。因此，小站君建議大家在準(zhǔn)備托福閱讀時(shí)別太過于迷信機(jī)經(jīng)，不要認(rèn)為背了真題機(jī)經(jīng)考試時(shí)問題就能迎刃而解，請從心態(tài)上就擺脫對托福閱讀真題機(jī)經(jīng)的依賴。

從2020年開始，托福考試每個(gè)考場會(huì)出現(xiàn)兩套以上的不同考題，所以托福閱讀考試的變數(shù)越來越大，即便是機(jī)經(jīng)也很難準(zhǔn)確預(yù)測。大家一定要理性看待托福閱讀機(jī)經(jīng)，不要過分依賴機(jī)經(jīng)。打好基礎(chǔ)，提高做題能力才是關(guān)鍵!

托福閱讀真題原題+題目

There are only a few clues in the rock record about climate in the Proterozoic eon. Much of our 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 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 processes 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 early 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 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 dropstones, 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 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 no 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.
