SKILLS 1 — Reading & Speaking
Câu 1 — Work in pairs. Discuss the following questions.
Đề bài:
- What do you know about other planets?
- Would you like to live on another planet? Why / Why not?
Cách giải
Đây là bài thảo luận theo cặp. Dưới đây là gợi ý trả lời:
1. What do you know about other planets?
I know that there are eight planets in our solar system. Some planets like Mars and Venus are rocky, while others like Jupiter and Saturn are gas giants. Mars is called the "Red Planet" because of its reddish appearance. Most planets cannot support human life because they are too hot, too cold, or have no air.
2. Would you like to live on another planet? Why / Why not?
Yes, I would like to live on another planet because it would be an exciting adventure. I could explore new places and see amazing things. / No, I wouldn't like to live on another planet because Earth has everything I need — clean air, water, and my family is here.
Câu 2 — Read the text and match the highlighted words in the text with their meanings.
Đề bài: Nối các từ được tô đậm trong bài đọc với nghĩa tương ứng.
Các từ cần nối:
- liquid
- gravity
- habitable
- promising
- traces
Các nghĩa:
- a. suitable for people to live in
- b. marks, objects, or signs that show that somebody or something existed
- c. in the form of a substance that flows freely and is not a solid or a gas
- d. the force that causes something to fall to the ground
- e. showing signs of being good or successful
Cách giải
Dựa vào ngữ cảnh trong bài đọc:
- liquid (chất lỏng) → phải ở dạng chảy tự do, không phải chất rắn hay khí
- gravity (trọng lực) → lực khiến vật rơi xuống đất
- habitable (có thể ở được) → phù hợp để con người sinh sống
- promising (đầy hứa hẹn) → có dấu hiệu tốt đẹp, thành công
- traces (dấu vết) → dấu hiệu cho thấy thứ gì đó đã tồn tại
Đáp án: 1. liquid — c (in the form of a substance that flows freely and is not a solid or a gas) 2. gravity — d (the force that causes something to fall to the ground) 3. habitable — a (suitable for people to live in) 4. promising — e (showing signs of being good or successful) 5. traces — b (marks, objects, or signs that show that somebody or something existed)
💡 Mẹo nhớ: "Gravity = Gravi-TY = Trọng lực Y" — lực kéo mọi thứ xuống. "Habitable = Habit (sống) + able (có thể)" = có thể sống được.
Câu 3 — Read the text again and answer the following questions.
Đề bài:
- What are humans still wondering nowadays?
- Why does a habitable planet need to have the correct amount of air?

Đáp án: Humans are still wondering what planets in outer space might support life.
2. Why does a habitable planet need to have the correct amount of air?
Thông tin từ bài: "the planets need to have the correct amount of air so that they can hold an atmosphere around."
Đáp án: Because it needs the correct amount of air so that it can hold an atmosphere around.
3. What happens if a planet is too small?
Thông tin từ bài: "If a planet is too small, its gravity is not strong enough to hold an enough amount of air."
Đáp án: If a planet is too small, its gravity is not strong enough to hold an enough amount of air.

5. Why can we not live on Mars?
Thông tin từ bài: "the climate on Mars is unsuitable for human life because it is too cold and Mars lacks oxygen to support human life."
Đáp án: Because the climate on Mars is too cold and Mars lacks oxygen to support human life.
Câu 4 — Tick (✓) the boxes to show what conditions a planet needs to support human life.
Đề bài: Chọn các điều kiện cần thiết để một hành tinh hỗ trợ sự sống con người.
- There must be enough liquid water on the planet.
- The planet must have craters on its surface.
- The planet must hold an atmosphere.
- The planet must have at least two moons.
- The planet must have enough oxygen in the air.
Cách giải
Dựa vào bài đọc, ba điều kiện chính là:
- Có nước ở dạng lỏng (nhiệt độ phù hợp)
- Có đủ không khí để giữ bầu khí quyển
- Kích thước phù hợp (trọng lực đủ mạnh)
Ngoài ra, bài cũng đề cập Mars thiếu oxy nên không sống được → cần oxy.
Đáp án: 1. ✓ (Phải có đủ nước lỏng — đúng theo bài: "they must have liquid water") 2. ✗ (Bài không đề cập đến hố va chạm — craters không phải điều kiện) 3. ✓ (Phải giữ được bầu khí quyển — đúng theo bài: "hold an atmosphere around") 4. ✗ (Bài không đề cập đến mặt trăng — không phải điều kiện) 5. ✓ (Phải có đủ oxy — đúng theo bài: "Mars lacks oxygen to support human life")
Can you add other conditions for a habitable planet?
Gợi ý thêm: The planet must have a suitable temperature (not too hot, not too cold). The planet must have the right size so that its gravity can hold enough air.
Câu 5 — Work in groups. Talk about the conditions you think are required for a planet to support human life.
Đề bài: Làm việc nhóm, thảo luận về các điều kiện cần thiết.
Cách giải — Bài nói mẫu
Gợi ý bài nói: There are some conditions planets must have to support human life on them. First, the most important condition is that there must be enough liquid water on the planet. Water is essential for all living things. Second, the planet must hold an atmosphere with enough oxygen so that humans can breathe. Third, the temperature must not be too high or too low. If it is too hot or too cold, humans cannot survive. Finally, the planet must have the right size. If it is too small, its gravity cannot hold enough air. If it is too big, its gravity will be too strong. In conclusion, finding a habitable planet is very difficult.
