The comprehension passages on this course are designed to help you increase your speed. A higher reading rate, with no loss of comprehension, will help you in other subjects as well as English, and the general principles apply to any language. Naturally, you will read every book at the same speed. You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook but you can raise your average reading speed over the whole range of materials you wish to cover so that the percentage gain will be the same whatever kind of reading you are concerned with.
The reading passages which follow are all of an average level of difficulty for your stage of instruction.
If you get to the point where you can read books of average difficulty at between 40 and 50 w.p.m. with 70% or more comprehension, you will be doing quite well, though of course any further improvement of speed with comprehension will be a good thing.
When you practice reading with passages shorter than book length, do not try to take in each word separately, one after the other. It is much more difficult to grasp the broad theme of the passage this way, and you will also get stuck on individual words which may not be absolutely essential to a general understanding of the passage. It is a good idea to skim through the passage very quickly first (say 500 words in a minute or so) to get the general idea of each paragraph. Titles, paragraph headings and emphasized words (underlined or in italics) can be a great help in getting this skeleton outline of the passage.
To do the most effective reading, you should ().
A. try every possible means to increase your reading rate
B. above all improve your comprehension of the text
C. hunt for whatever is implied in the reading material
D. increase your reading speed and improve your understanding
参考答案：D
解析：
本题是细节题。文中第三段提到在提高阅读速度的同时，同时也要有好的理解，有效的阅读应该具备这两点。A、B选项只是有效阅读的一个方面，原文第一段第二句中的A higher reading rate, with no loss of comprehension, will help you...已经点明了有效阅读的这两个因素。C选项原文未提及。
