For many people today, reading is no longer relaxation To (31) their work they must read letters, reports, newspapers... In getting a job or advancing in one, the ability to read and comprehend (32) can mean the (33) between success and failure. Yet the unfortunate fact is that most of us are poor readers. Most of us (34) poor reading habits at an early age, and never get (35) them. The main (36) lies in the actual stuff of language itself—words. (37) individually, words have little meaning (38) they are strung together into phrased, sentences and paragraphs. (39) , however, the untrained reader does not read groups of words. He laboriously reads one word (40) often regressing to read words or passages. Regression, the (41) to look back over (42) you have just read, is a common bad habit in reading. Another habit which (43) down the speed of reading is vocalization—sounding each word either orally or mentally (44) one reads. To (45) these bad habits, some reading clinics use a device (46) an accelerator, which moves a bar down the page at a predetermined speed. The bar is set at a slightly faster rate than the reader finds (47) , in order to "stretch" him. The accelerator forces the reader to read fast, making word-by-word reading, regression and subvocalization, (48) impossible. At first (46) is sacrificed for speed. (50) when you learn to read ideas and concepts, you will not only read faster, but your comprehension will improve.
A. if
B. as
C. even
D. before

It is hard to track the blue whale, the ocean’’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’’s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption (爆发) for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second -- slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’’s chest to a doctor’’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles. Which of the following is true about the U.S. Navy underwater listening network
A. It is now partly accessible to civilian scientists.
B. It has been replaced by a more advanced system.
C. It became useless to the military after the cold war.
D. It is indispensable in protecting endangered species.
