Review of Grammar, Vocabulary, and Reading Comprehension

Welcome to this comprehensive English language course designed for learners who want to strengthen their grammar, expand their vocabulary, and improve reading comprehension. The lessons below are built around real‑world quiz questions, providing clear explanations, examples, and practice tips. By the end of the course you will be able to use past‑tense constructions, articles, and prepositions confidently, understand key environmental vocabulary, and recognize cultural nuances in communication.

1. Describing Two Past Actions – The Past Continuous vs. Simple Past

Key concept: When you talk about two actions that happened in the past, the action that was ongoing at the moment another action occurred is expressed with the past continuous (was/were + verb‑ing). The other action, which interrupts or occurs at a specific point, uses the simple past.

Example from the quiz:

• "When I met him, he was living in London." – was living is the ongoing action.
• "He lived in London before that." – lived is the completed past action.

Why the other options are incorrect:

• "He will live in London" – future tense, not past.
• "He has lived in London before" – present perfect, not the specific past moment.
• "He has lived in London and still lives there" – present perfect + present, again not the past‑continuous pattern.

Practice tip: When you hear a sentence with "when" or "while," look for the verb‑ing form to identify the background action.

2. Using Articles with General and Specific Weather Descriptions

English articles (a, an, the) can be tricky, especially with uncountable nouns like weather. The rule of thumb:

• Use the when you refer to a specific, known instance of weather.
• Use no article when you talk about weather in a general sense.

Quiz sentence: "We are having ___ terrible weather. Usually ___ weather in the UK is not this bad." The correct choice is no article – the:

• "We are having terrible weather." – general, no article.
• "Usually the weather in the UK is not this bad." – refers to the typical weather pattern, a specific context, so we use the.

Remember: the can also appear before adjectives when the noun is implied (e.g., "the cold" meaning "the cold weather").

3. Choosing the Correct Preposition After "Thank"

In English, the verb thank is followed by the preposition for when you express gratitude for an action or a thing.

Correct sentence: "Mr. John thanked me for helping him."

Why the other options don’t work:

• to is used with "thank" only when the object is a person (e.g., "thank you to John" – which is actually incorrect; the correct form is "thank John").
• on and of are not used after "thank" in standard English.

Memory trick: Think of the phrase "thank for" as a pair – they always go together, just like "look at" or "listen to".

4. Vocabulary: Describing Contaminated Water

Environmental topics often require precise adjectives. The water that cannot be drunk because of lead contamination is described as polluted ("bị ô nhiễm").

Other options explained:

• "Đã phân loại" – means "classified"; unrelated to water quality.
• "Đã phân hủy" – means "decomposed"; not a description of safety.
• "Đã tái chế" – means "recycled"; again unrelated.

Example sentence: "The river is polluted with heavy metals, making it unsafe to drink."

5. Understanding the Term "Carbon Footprint"

When discussing climate change, the phrase carbon footprint refers to the total amount of greenhouse gases emitted directly or indirectly by human activities.

In the quiz, the correct Vietnamese translation is "Dấu chân carbon" – the literal term used in many sustainability reports.

Related vocabulary:

• Emission – the release of gases into the atmosphere.
• Mitigation – actions taken to reduce emissions.
• Renewable energy – energy sources that do not add to the carbon footprint.

Tip for learners: When you see "footprint" in environmental contexts, think of it as a metaphor for the impact left behind, just like a physical footprint on sand.

6. The Verb "Decompose" in the Context of Plastic Bags

Plastic bags are often described as decomposing slowly. The verb "decompose" means to break down into simpler substances, usually by natural processes.

Correct answer from the quiz: "Phân hủy" (the Vietnamese verb for "decompose").

Other options such as "thải ra" (to discharge), "tái sử dụng" (to reuse), and "tái chế" (to recycle) describe different actions and are not appropriate when talking about the natural breakdown of material.

Example: "These biodegradable bags will decompose within six months, unlike conventional plastic that persists for centuries."

7. Cultural Etiquette: Handshakes in Different Regions

Non‑verbal communication varies across cultures. According to the reading passage, people in some Middle Eastern countries tend to shake hands gently and hold the grip a little longer compared to Western norms.

Why the other regions are incorrect:

• In the United States and Canada, handshakes are typically firm but brief.
• Latin American cultures often use a light handshake followed by a cheek kiss.
• "Bắc Mỹ" (North America) is too broad and does not capture the specific Middle Eastern practice.

Practical tip: When meeting someone from a Middle Eastern background, a gentle, slightly prolonged handshake shows respect and aligns with local customs.

8. Historical Fact: The Founders of Apple Inc.

Steve Jobs and Steve Wozniak co‑founded Apple in 1976. This iconic technology company started in a garage and grew into a global leader in consumer electronics.

Common misconceptions:

• Apple is not the same as Macintosh (which is a product line of Apple).
• Microsoft was founded by Bill Gates and Paul Allen, not the Steves.
• Pixar is a separate animation studio, later acquired by Disney.

Remember the timeline: 1976 – Apple founded → 1984 – Macintosh released → 2001 – iPod → 2007 – iPhone.

9. Integrating All Concepts – Sample Reading Passage

Read the short passage below and answer the questions that follow. This exercise combines grammar, vocabulary, and cultural knowledge.

When I visited London last summer, I was staying in a small flat near the Thames. The weather was terrible – the rain never stopped. During my stay, I met a local environmental activist who thanked me for helping organize a river‑clean‑up. He explained that the water was polluted with lead, and that reducing the carbon footprint of flights could help protect the river. He also mentioned that most plastic bags decompose very slowly, which is why the city is promoting biodegradable alternatives. When we shook hands, he gave me a gentle, lingering handshake, a custom he said is common in some Middle Eastern countries.

Questions for practice:

• Identify the past‑continuous verb and explain why it is used.
• Find the two places where articles are correctly applied and rewrite the sentences without changing the meaning.
• List the environmental terms introduced in the passage and give a synonym for each.
• Describe the handshake etiquette mentioned and compare it with the typical handshake in your own culture.

Answering these questions will reinforce the grammar structures, article usage, prepositional phrases, and vocabulary you have learned.

10. SEO‑Friendly Study Tips

To make the most of your study sessions and improve searchability of your notes, follow these guidelines:

• Use clear headings: Include keywords like "past continuous," "article usage," and "environmental vocabulary" in your document titles.
• Add meta‑descriptions: Write a 150‑character summary for each topic (e.g., "Learn how to use past continuous for two past actions in English.")
• Incorporate internal links: Connect related sections (e.g., link the "Carbon Footprint" section to a page about "Renewable Energy").
• Practice with quizzes: Create flashcards using the quiz format above; spaced repetition improves retention.
• Optimize images: If you add diagrams of handshake styles, use alt text such as "Middle Eastern handshake etiquette".

By structuring your notes with semantic HTML tags (h2, h3, p, ul, li) you not only make them easier to read but also improve their visibility on search engines.
