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．____（46）
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）____（47）
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．___（48）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 gone through the special tutoring，and they continued to do well in reading tests．___（49）
However，some researchers still doubt the study_____（50）
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 all 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
46 c 文章的题目是：用较快的速度阅读。第二段的第一个句子说的是：在美国五个小学生中至少有一个在学习阅读方面有困难，虽然这些学生其他科目都不错。这是一个总的说明，接着的句子应该具体化了。c就是进一步的说明：科学家说：这些孩子中的许多人的最大困难是如何使得读音和字母对应起来。
47 B 第四段的第一句话说的是：每天老师帮助他们弄懂字母如何表达叫做音素的语音单位的。光弄懂是不够的，还需要实践。B就是实践：学生还练习朗读和拼写。
48 E 第六段说的是：作为研究的一部分，研究人员用一个特殊的机器拍摄学生大脑的动作照片。B说的是：照片显示左大脑后部的活动增加了。非常连贯。
49 D 倒数第二段的第一句讲的是试验组的情况，D讲的是用传统方法的情况。放在一起可以构成对比，也很连贯。
50 F 最后一段的第一句说的是：然而，有些研究人员仍然不太相信这一研究。从提供的选项中的第一个词组可以看出，只有F是合适的，因为它的起始词是“They'，回指”some researchers“。
