Answer:
One source of energy I know is solar energy. It comes from the sun and can be found everywhere on Earth. Solar energy is used to generate electricity through solar panels, and it also helps plants grow through photosynthesis. I use solar energy indirectly every day when I turn on lights or use electronic devices powered by electricity generated from solar power.

Mẫu thư (khoảng 150-200 từ):

Dear friend,
I hope you are doing well. I want to tell you about my part-time job in an office. I work as an assistant at a local company. My main tasks include answering phone calls, organizing documents, and helping with simple data entry. I usually work in the afternoons after school.
This job helps me learn new skills like communication, teamwork, and using office software. Although it is sometimes tiring, I enjoy working because it gives me experience for the future.
I also get to meet many different people and improve my confidence. Besides, the salary I earn helps me save money for my personal needs.
I think working part-time is useful for students to gain practical experience and responsibility.
What about you? Do you have any part-time jobs? Please write back and tell me about them.
Best regards,
[Your Name]

Dưới đây là cách viết lại câu sử dụng từ "despite" (hoặc "in spite of"):

👉 Hydropower can have negative impacts on marine life despite being a clean energy source.

Hoặc bạn cũng có thể viết:

👉 Hydropower can have negative impacts on marine life in spite of being a clean energy source.

✅ Cấu trúc:

• despite/in spite of + V-ing / noun / noun phrase

Câu bạn đưa:
Some relatives of mine like staying at their cabin on Lake Omega every summer holidays.

Các từ in đậm là lỗi sai bạn nói, mình sẽ kiểm tra từng từ:

• Some relatives of mine: Câu này đúng, không sai.
• like staying: cũng đúng, diễn đạt sở thích.
• at their cabin: đúng.
• on Lake Omega: đúng.
• every summer holidays: sai về cách dùng từ.

Lỗi sai chính là cụm "every summer holidays".
Từ "every" đi với danh từ số ít hoặc không đếm được. "Holidays" là số nhiều, nên không dùng "every holidays".

Cách sửa:

• "every summer holiday" (mùa hè mỗi năm)
  hoặc
• "every summer" (mùa hè mỗi năm)
  hoặc
• "during the summer holidays" (trong kỳ nghỉ hè)

Câu sửa đúng:

• Some relatives of mine like staying at their cabin on Lake Omega every summer.
  hoặc
• Some relatives of mine like staying at their cabin on Lake Omega during the summer holidays.
