广泛的托福阅读背景知识积累，有助于新托福阅读速度和准确率的提升。托福阅读题材分为自然科学、人文科学、互联网等几大类，如果同学们平时能对这些种类的文章都有所涉猎，托福阅读考试中遇到相关的话题就会有非常熟悉的感觉。下面天道教育给大家提供一篇关于手指能感应打字是否正确的材料，希望能拓宽同学们的阅读面。
　　打字错误是谁都难以避免的，但是据最新研究得出的结论是，我们的手指能感应到打字正确与否。
　　Whether you're a hunt-and-peck typist or a Rachmaninoff of the keyboard, you will make mistakes. But it's not just your eyes catching typos when you see them on the screen. Your hands know when you mess up too. That’s according to a study in the journal Science. [Gordon Logan and Matthew Crump, "Cognitive Illusions of Authorship Reveal Hierarchical Error Detection in Skilled Typists"]
　　Researchers recruited expert typists—college students, of course—and showed them 600 five-letter words, one at a time. And they asked the students to type those words as quickly and accurately as possible. But sometimes, the researchers inserted typos in the word as it appeared on screen, when the students hadn’t made one. Other times they automatically corrected typos the students did make.
　　And the students tended to believe the screen. So if a typo had been added, they figured they must have messed up. If a typo had been corrected they thought they typed it right. But the hands didn't fall for it. When the fingers slipped up, they paused a split second longer than usual before typing the next letter. But they didn't pause when fake typos appeared on-screen only. So we apparently have two discrete mechanisms guarding against typing errors, one visual, the other tactile. To fox quick brown fixes. To fix quick brown foxes.
