问题     Now let us look at how we read. 74. When we read a printed text, our eyes move across a page in short, jerky movement. We recognize words usually when our eyes are still when they fixate. Each time they fixate, we see a group of words. This is known as the recognition span or the visual span. The length of time which the eyes stop the duration of the fixation varies considerably from person to person. It also vaies within any one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors as lighting and tiredness.
    Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, seeing, a tenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation. All these exercises are very clever, but it’ s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seem unlikely to help him in reading a continuous text.
What does the author mean by saying "but it’ s one thing to improve a person’ s ability to see words and quite another thing to improve his ability to read a text efficiently. " in the second parapraph?
选项 A、The ability to see words is not needed when an efficient reading is conducted.
B、The reading exercises mentioned can’t help to improve both the ability to see and to comprehend words.
C、The reading exercises mentioned can’t help to improve an efficient reading.
D、The reading exercises mentioned has done a great job to improve one’ s ability to see words.
答案C
解析 作者在这句话中先是肯定了那些阅读练习提高看单词的能力，然后提出了有效阅读概念。后面句中还指出，有效阅读需要的是理解单词间的联系的能力。所以作者的意思应该是那些(训练眼睛的)阅读练习对于有效的阅读无益。B与文章相反。D句是蕴涵其中一个意思，却不是作者想表达的方向。
