Kỹ năng ngữ pháp và từ vựng tiếng Anh

Welcome to this comprehensive English language course designed for learners who want to strengthen both grammar and vocabulary. The lessons below are built around real‑world quiz items, so you’ll practice the exact structures that appear in tests, exams, and everyday communication. Each section explains the rule, provides clear examples, and offers tips for remembering the pattern.

1. Gerunds vs. Infinitives – Choosing the right verb form

In the sentence “Having a balanced diet and ________ regularly are good ways to stay healthy,” the blank must be filled with a verb that matches the structure having … and …. Because the subject is a list of activities, we need a gerund (verb + -ing) that functions as a noun.

• working out – correct. It is a gerund meaning “to exercise”.
• taking out – a phrasal verb, but not a gerund that fits the health‑related context.
• speaking out – refers to expressing an opinion, not a physical activity.
• hanging out – means “spending time together”, which does not convey the intended health benefit.

Tip: When a sentence lists two activities after having, both should be gerunds (e.g., eating and exercising).

2. Prepositions of Effect – “on” vs. “at”, “in”, “for”

The phrase “positive effect (1) ______ your physical and mental health” requires the preposition that links an effect to its target. The correct choice is on.

• on – used to indicate influence or impact (e.g., “effect on the environment”).
• at – usually indicates a location or a point in time, not influence.
• in – can mean “inside” but not “affecting”.
• for – expresses purpose, not impact.

Memory cue: Imagine a spotlight shining on someone; the light represents the effect.

3. Relative Pronouns – Choosing “which” for non‑restrictive clauses

In the sentence “These disagreements, (2) ______ are common in many families,” the blank calls for a relative pronoun that introduces a non‑restrictive clause (extra information about “disagreements”). The correct answer is which.

• which – introduces non‑restrictive clauses and is followed by a comma.
• who – refers to people, not abstract nouns like “disagreements”.
• where – refers to places.
• whose – indicates possession.

Rule of thumb: Use which for things, who for people, and remember that non‑restrictive clauses are set off by commas.

4. Phrasal Verbs – Understanding “cut down on”

The expression “cut down on” means to reduce something, especially consumption or frequency. In the nutrition context, the correct translation is giảm bớt.

• tăng lên – means “increase”.
• lựa chọn – means “choose”.
• bảo quản – means “preserve”.
• giảm bớt – correct, aligns with “cut down on sugar”.

Quick tip: If you can replace the phrase with “reduce”, you have the right meaning.

5. Linking Lifestyle to Longevity – Vocabulary for healthy habits

One quiz item asks why wealthy people in Vietnam tend to live longer. The answer is that they have healthier lifestyle habits. This highlights two important vocabulary clusters:

• healthy habits – regular exercise, balanced diet, adequate sleep.
• lifestyle – the way a person lives daily, encompassing diet, activity, stress management, and social connections.

Understanding these collocations helps you discuss health topics fluently.

6. Past Simple vs. Other Tenses – Choosing the correct verb form

In the sentence “The doctor ______ my blood pressure yesterday and said it was normal,” the blank must be filled with a past‑simple verb because the action happened at a specific time (“yesterday”). The correct form is checked.

• will check – future tense.
• has checked – present perfect, which does not specify a past time.
• checks – present simple, unsuitable for a completed past event.
• checked – past simple, matches “yesterday”.

Remember: Use the past simple when a sentence includes a clear past time marker (yesterday, last week, in 1999, etc.).

7. Consistency in Advertising Language – Re‑using prepositions

The advertisement for “Fit for Life Week” repeats the phrase “positive effect (1) ______ your physical and mental health.” As covered earlier, the correct preposition is on. Repeating the same structure in marketing copy reinforces clarity and SEO relevance.

8. Defining “Generation Gap” – Vocabulary for inter‑generational differences

One of the quiz statements asks which description best matches the term “generation gap”. The accurate definition is the difference in viewpoints between generations. This concept is frequently discussed in sociology, family studies, and media.

• Decrease in family traditions – not the core idea.
• Rapid economic growth – unrelated.
• Uniform thinking across ages – opposite of a gap.
• Differences in perspectives between generations – correct.

Key collocations: generation gap, inter‑generational conflict, cultural differences.

9. Integrating All Concepts – Practice Exercise

Combine the rules you have learned to complete the following paragraph. Fill in the blanks with the appropriate words or phrases.

Having a balanced diet and __________ regularly are essential for good health. A positive effect __________ your physical and mental well‑being can be achieved by cutting down on sugary drinks and choosing nutritious foods. The doctor __________ my blood pressure last week, confirming that my lifestyle changes are working. In many families, the generation gap __________ evident when older members prefer traditional meals while younger members opt for fast food. Understanding these differences helps us create healthier habits for everyone.
  

Answers: working out; on; checked; is; (use the gerund “working out” and the preposition “on”; past simple “checked”; present simple “is” for a general truth).

10. SEO Tips for Language Learners

When you create content about English grammar or vocabulary, keep these SEO best practices in mind:

• Use clear headings (h2, h3) that contain target keywords like “English grammar”, “gerunds”, “prepositions”.
• Include synonyms and related terms throughout the text (e.g., “exercise”, “physical activity”, “healthy habits”).
• Write concise, informative paragraphs – aim for 40‑60 words per paragraph to improve readability.
• Add internal links to other lessons on verb tenses or vocabulary building.
• Use alt text for any images you might add later, describing the visual content with relevant keywords.

By following these guidelines, your educational pages will rank higher in search results and attract more learners.

11. Summary of Key Points

• Gerunds (-ing) are used after “having” to list activities.
