Hello Jack: I can offer you a few good references: http://www.learnamericanenglishonline.com/Blue%20Level/B1%20Be.html http://www.howjsay.com/index.php?word=contraction&submit=Submit = Talking Dictionary in English http://www.spellingcity.com/which-word-best-completes-the-sentence.html?listId=18026286 http://www.myenglishpages.com http://www.englishlanguageguide.com/grammar/ -------------------------------------------------------------- you can also discuss these lessons with a Language Partner. ---------------------------------------------------------- However, if you assume that this is the best way to "learn English" that would not be true. Your practices in pronunciation should come first, in association with printed lesson material. .

To learn English Grammer, you need to know the basic steps- Every single word can be categorized into one of eight word groups, or parts of speech. The Eight Parts of Speech are- Nouns Pronouns Verbs Adjectives Adverbs Prepositions Conjunctions Interjections With knowing the meanings of each parts, it would help you in making the right sentences and how to fix your words correctly

Practice. Your sentences are a lot better than you think!
