Q. Are there any occasions when reading at speed is a useful skill to have? 
What are they? 
Well, there are some particular occasions when someone needs to read at a 
speed. When you are complete a large chapter for your examination, you need 
to be a quick reader. It happens before the examination that the students are 
to race against time and thus they need to read in a speedy mode. Further, 
when you are seeking something important, particularly on newspaper, you 
need to read quickly. The newspapers are filled with numerous information 
and you are to sort out specific information for your needs. Speedy readings 
will be a helpful skill for you at that time. Moreover, when you need to find out 
any specific lines from a book or any text, speedy reading is the most effective 
way.
