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 applied 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, hut 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. They are all proximately 500 words long. They are about topics of general interest which do not require a great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English, with understanding, at say, 400 words per minute (w. p. m.), you might skim through a newspaper at perhaps 650-700 w. p. m., while with a difficult textbook you might drop to 200 or 250 w. p.m.
If you get to the point where you can read books of average difficulty at between 400 and 500 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 practise reading with passage 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.
