托福閱讀可以修改答案嗎

很多同學(xué)都很關(guān)注托福閱讀可以修改答案嗎這個問題，那么接下來就跟著中國教育在線小編一起來看看吧，相信你通過以下的文章內(nèi)容就會有更深入的了解。

托福 閱讀可以修改答案嗎

托福閱讀是有時間要求的。閱讀時間為1個小時，沒次閱讀三篇文章。每篇文章700個字左右，每篇文章大概有14道題目。比如說：你在回答后面文章第12道題的時候，發(fā)現(xiàn)你前面第3道題寫錯了，可以返回更改答案的。

托福閱讀考試猜題技巧

托福閱讀考試中如果遇到一些難題或者比較消耗時間的題目，比較合理的做法并非硬著頭皮做題，而是快速猜個答案繼續(xù)做后面的題目，這就需要用到猜題技巧。如何才能在提升解題速度的同時保證猜題的正確率?用好猜題技巧有哪些注意要點?下面小編就為大家具體分析講解。

托福閱讀為什么需要猜題?

托福閱讀之所以需要猜題，是因為猜題能夠幫助考生解決許多問題，其中主要的就是因為時間不足而引發(fā)的一系列影響考生發(fā)揮的連鎖反應(yīng)。時間不足不僅會打亂考生的答題節(jié)奏，因為難題不會做而耗費時間同時也會對大家造成巨大的心理壓力，甚至影響到考生在閱讀之后其它考試部分的發(fā)揮。而合理猜題不僅能緩解時間壓力，讓大家有更多時間應(yīng)對其它題目做完所有閱讀題，本身也能保證一定的正確率讓考生不用太掛心猜的題目，從心理上穩(wěn)定大家的考試心態(tài)。因此，在托福閱讀中合理地運用猜題技巧對考生來說是利遠大于弊的。

托福閱讀哪些題目要猜題?

那么，托福閱讀中哪些題目需要用到猜題技巧呢?小編認為，一些對文章主題內(nèi)容提問的題目或者本身做起來就有一定難度的題目是合理猜題的主要針對目標。比如大家都很熟悉的每篇閱讀最后基本都會出現(xiàn)的6選3小結(jié)題就可以用猜題的方式來應(yīng)對。這類題目往往會問到整篇文章中的各個段落細節(jié)的相關(guān)內(nèi)容，正常做題時考生往往需要逐一去核對尋找選項內(nèi)容才能解答，這類題目做起來不僅費時也費力，因此在考試時間比較緊張的情況下通過猜題的方式來較為快速的解決才是比較符合得分效率的應(yīng)對方法。面對這類題目，小編建議大家可以適當(dāng)運用猜題技巧來緩解時間和難度壓力。

托福閱讀中如何使用猜題技巧?

接下來小編就為大家具體介紹托福閱讀中使用猜題技巧的方法：

1. 結(jié)合背景知識猜題

大家都知道，托福閱讀考試涉及到的學(xué)科內(nèi)容主題是比較廣泛的，許多同學(xué)為了能夠更快地看懂理解閱讀文章都會在備考中提前補充一些各方面的常識性基礎(chǔ)知識。而小編認為猜題其實也可以結(jié)合背景知識來進行。舉例來說，如果一篇閱讀文章講到了一個文學(xué)概念或者是某個作家的生平事跡，那么考生如果之前已經(jīng)了解過這方面的信息，在做題過程中面對一些題目就可以通過積累的背景知識來進行合理猜題，一些明顯不符合大家對這個文學(xué)概念或者作家認知的選項就可以直接排除掉了。這樣一來即使考生沒有返回原文進行詳細尋找參考，也可以比較有效地快速縮小選擇范圍提升猜題正確率。

2. 通過整體理解猜

現(xiàn)在閱讀考生中很多同學(xué)采取的解題方式都是邊看文章邊做題，這種方法依托于托福閱讀出題都是按照文章段落順序出題的機制，可以說是非常有效率的閱讀解題兩不誤的方法。而通過這種方法做題，考生在面對一些出現(xiàn)順序考后的題目比如之前說過的小結(jié)題或者是結(jié)構(gòu)題時其實對文章已經(jīng)有了一定的整體認識和理解，在這種前提下大家完全可以做到不再回原文定位查找，直接憑借之前閱讀印象就能對選項進行分辨排除。這也是一種比較有效且能夠保證正確率的猜題方式。

3. 核心技巧是先排除再猜題

當(dāng)然，無論是怎么猜題，猜題的核心技巧就在于先排除再猜題。如果考生沒有對題目有過任何了解，那么猜題其實就等于是在瞎猜，而先完成審題步驟，仔細讀完了題目和所有選項，把一些明顯存在問題的選項先行篩選排除掉，之后再剩余選項中猜測正確答案，這樣的做法才能稱得上是猜題技巧，想要在猜題的同時保證正確率的目標也才能真正達成。

托福閱讀文本：

During the second half of the nineteenth century, the production of food and feed crops in the United States rose at an extraordinarily rapid rate. Corn production increased by four and a half times, hay by five times, oats and wheat by seven times. The most crucial factor behind this phenomenal upsurge in productivity was the widespread adoption of labor-saving machinery by northern farmers. By 1850 horse-drawn reaping machines that cut grain were being introduced into the major grain-growing regions of the country. Horse-powered threshing machines to separate the seeds from the plants were already in general use. However, it was the onset of the Civil War in 1861 that provided the great stimulus for the mechanization of northern agriculture.

With much of the labor force inducted into the army and with grain prices on the rise, northern farmers rushed to avail themselves of the new labor-saving equipment. In 1860 there were approximately 80,000 reapers in the country; five years later there were 350,000.

After the close of the war in 1865, machinery became ever more important in northern agriculture, and improved equipment was continually introduced. By 1880 a self-binding reaper had been perfected that not only cut the grain, but also gathered the stalks and bound them with twine. Threshing machines were also being improved and enlarged, and after 1870 they were increasingly powered by steam engines rather than by horses. Since steam-powered threshing machines were costly items — running from $ 1,000 to $4,000 — they were usually owned by custom thresher owners who then worked their way from farm to farm during the harvest season. "Combines" were also coming into use on the great wheat ranches in California and the Pacific Northwest. These ponderous machines — sometimes pulled by as many as 40 horses — reaped the grain, threshed it, and bagged it, all in one simultaneous operation.

The adoption of labor-saving machinery had a profound effect upon the sale of agricultural operations in the northern states — allowing farmers to increase vastly their crop acreage. By the end of century, a farmer employing the new machinery could plant and harvest two and half times as much corn as a farmer had using hand methods 50 years before.
