English grammar course

The heaviest part for Vietnamese learners: verbs inflect for tense and person. All 12 tenses, the continuous and perfect aspects, plus irregular verbs.

English questions and negatives borrow the auxiliaries do/does/did and front them before the subject — the step Vietnamese speakers most often skip.

can, must, should, may, would… The verbs that carry nuance: ability, obligation, advice, deduction — in both present and past-speculation forms.

How to describe and rank: adjective position, the -ly adverb ending, and all three degrees — as…as, comparative, superlative.

some/any, much/many, a few/a little… Picking the right quantifier forces the countable vs uncountable split that Vietnamese does not mark.

The words that join things up: in/on/at for place and time, and/but/because linking clauses, plus ways to express points and spans of time.

be + past participle to promote the object, and have/get something done when someone else does the work — both dense in formal writing.

Embedding one sentence inside another: relative clauses with who/which/that, noun clauses, and reported speech with backshift.

All four conditional types, the subjunctive and mixed forms — how to talk about the likely, the unlikely, and what never happened.

Fronting the auxiliary after Never, Not only, Hardly…, plus cleft sentences It is… that and other emphatic patterns — markers of advanced style.

The part no rule predicts — learn them whole: phrasal verbs, collocations, fixed expressions and common spoken patterns.

The final polish: English punctuation, confusable word pairs, and the mistakes Vietnamese speakers make most from translating word for word.
