Read With Greater Speed
Do you have difficulty reading in class? If so, a special reading program that helps match sounds with letters could speed up your brain.
At least one out of every five elementary school students in the US has trouble learning to read, even when the students are good at other subjects. （1）
Researchers from Yale University, US, studied a group of children from New York and Connecticut State. As part of the study, 37 struggling readers received special tutoring.
Every day, instructors worked with them on recognizing how written letters represent units of sound called phonemes （音素）. （2）
By the end of the school year, these children could read faster than before. They also made fewer mistakes, and understood more of what they read than they could earlier in the year.
As part of their study, the researchers used a special machine to take action photos of the students' brains.
（3） This is the same part of the brain that becomes active when good readers read. This activated brain area appears to include a structure that helps people recognize familiar written words quickly. In lower level readers, this structure remains inactive.
A year later, the brain structure was still working hard in the students who had gore through the special tutoring, and they continued to do well in reading tests （4）
However, some researchers still doubt the study. （5）
A Many adults are interested in matching sounds with letters
B The students also practiced reading aloud and spelling
C The biggest challenge for many of these kids, scientists say, is matching sounds with letters.
D Another group in the study who went through a more traditional reading program didn't show the same progress.
E The pictures showed an increase in activity in the back of the brain on the left side.
F They believe that reading without making any noise or linking words to sounds is more efficient.
【参考答案】1. C 2. B 3. E 4. D 5. F
1. C 这段话中有has trouble doing sth,美国的初中生（即使是成绩很好的）在阅读方面都有困难，那究竟是为什么呢？紧接着的一段话就开始将科学家们做实验求证。我们要了解，英语文章一般都会将文章的中心放在前面，然后再论证。所以这里应该是对问题的简单定义或者说明。选项中只有C才符合意思。
2. B 这段话主要就是讲实验的具体情况，recognizing how written letters...看一下选项中与实验具体内容比较接近的就是B了，The students also practiced...这里的also恰好也符合意思。
3. E 这个空出现在一段话的开始，很可能就是承上启下的句子，因此我们不仅要看后面的还要清楚前面的内容，前段话提到使用一种特殊的仪器拍出了学生们大脑的动态图片。a special machine to take action photos of the students' brains.后面的this 是same part of the brain，可见这里应该是和photos相关的内容。所以答案选E
4. D 这一段是讲测试的一些进展，其中有提到the students who had gore through the special tutoring，而另一部分人呢，很容易选出答案D,一般这种做实验对比的都会将被试验者分为两类，通过对比才会有所发现。
5. F However, some researchers still doubt the study。一些研究者仍然怀疑这项研究。选项F恰好是他们的理由，所以为正确答案。
