ESL Blogs

Yes, it makes sense to know sentence structure since a blog or an article is made of sentences - only when you can make sentences can you compose a piece of writing. 

Indeed, there are just 4 types of sentences: simple sentence, compound sentence, complex sentence, compound-complex sentence. For example:

1. Expector is a doctor. (simple sentence)

2. Expector is a doctor and he loves English. (compound sentence)

3. Expector, who is a doctor, is also a moderator of MyEC. (complex sentence)

4. Expector is a doctor and he is also a moderator of MyEC, where you can write blogs. (compound-complex sentence)

There are a large number of coordinating, subordinating conjunctions and relative pronouns that you can use to make a compound, complex or a compound-complex sentence. It's a good idea to use different kinds of sentences in your writing, which means you should vary your sentences.  

An example paragraph by Expector

Some members may argue that we shouldn't keep challenging our members to write. They think what really matters is what or how well our members write, not how many they can write. That is, quality is preferred to quantity. I wonder, however, whether they agree there is not a shortcut and more practice is necessary for anyone to excel at writing. Only when our members begin to write can they recognize that knowing all the grammar rules doesn't mean they can write skillfully. Besides, taking part in a writing or blog challenge makes it possible for others to read or even correct our members' blogs, from which they will benefit.

Sorry I used only the structure 'complex sentence' - please read a better example paragraph in the comments below. 

Why not give it a try - I'll correct you if you really mean 'correct me' by 'correction'!
