In my experience as a teacher over the years, I have noticed that students, regardless of which country they are from often overlook some basic rules in English. Here are a few examples of some basic mistakes that if corrected will help you sound more fluent.

 Preposition + verb ing

 This seems to be something that almost all students are unaware of but if you can remember this basic grammar rule it will really help you. Yes, it’s true, prepositions are always followed by the ing form of the verb. Simple, right?

 Wh Questions with Verb

 There are a couple of problems here but again, it’s basically an easy rule to make questions. If you have a main verb in the question you always need to use do or a form of do depending on the tense after the wh question word. The problem for some students is that they have problems identifying a verb. If this is you, you have to become very good at quickly knowing whether your working with a verb, adjective or noun.

 Wh Questions with Adjectives and Verbs

 Just like identifying verbs in questions, you have to be able to quickly know if you are using an adjective or noun. If so, forget about do and use an appropriate be verb after the wh question. The problem here is that even after years of studying grammar, many student still do not know what be verbs to use in their various tenses after pronouns. This is something that you can correct in a few hours or less of study.

 It’s surprising how these three basic problem areas continually haunt students yet they are so easy to master.
