[单项选择]

This ability to see words on either side of the point at which your eyes focus is called peripheral (周围的) vision. Foreign students of English often feel that it is impossible to recognize so many words at a single glance. It is difficult for many native speakers, but it can be done. It is something that has to be done if you are to read as rapidly as you should. You can increase your peripheral vision by eye exercises.
Equally important is the importance of moving your eyes from point to point in a uniform rhythm (以不变的节奏). Slow reading often results from regression (退回), the number of times your eyes have to go back. While practicing to increase your peripheral vision and uniform rhythm, you may occasionally have to go back to reread. Do not be discouraged. A smooth, forward rhythm comes with practice. Eventually your speed will get to the point where your eyes move comfortably forward without regression.
A final cause of slow reading is forming the sound of each
A. things far away
B. printed matter more clearly
C. a wider range of things
D. a whole sentence at one time

[单项选择]　　Most words are "lexical words", i.e. nouns signifying "things", the majority of which are abstract concepts rather than physical objects in the world; only "proper nouns" have specific and unique referents in the everyday world. The communicative function of a fully-functioning language requires the scope of reference beyond the particularity of the individual instance. While each leaf, cloud or smile is different from all others, effective communication requires general categories or "universals". Anyone who has attempetd to communicate with people who do not share their language will be familiar with the limitations of simply pointing to things, given that the vast majority of lexical words in a language exist on a high level of abstraction and refer to classes of things such as "buildings" or to concepts like "construction". 　　We lose any one-to-one correspondence of word and thing the moment we group instances into classes. Other than lexical words, language consists of "functio
