This is a good read and interesting article:
Whether we are talking about a five
year old that is about to start learning to read or whether we are talking
about a thirty year old woman who is attempting to write a thesis for her
master’s degree, we cannot deny the fact that taking time to learn proper
English grammar is important.
When we see or hear about English
grammar, the immediate reaction of many people I know is to cringe. They are
reminded of junior high and high school English class and the way that their
English teachers made them to English grammar exercise after exercise. Because
English grammar is usually seen in such a negative sense, it is all the more
important that people replace those lies with the truth that learning English
grammar really is important for anyone who wants to have a proper perspective
of the English language.
