Ứng dụng 😎 Linearthinking để giải quyết câu hỏi:
Câu cần điền là mệnh đề trong câu → Cần phân tích vế còn lại trong cùng 1 câu.
Step 1: Read the question
✏️ Read structure: S The Amazon Rainforest V - được biết đến nhờ sinh thái đa dạng is known for its rich biodiversity , Bổ nghĩa - (?) ______ .
🔮 Predict:
Vì trước đó đã có cấu trúc hoàn chỉnh S + V (The Amazon Rainforest is known...) → ngầm hiểu: The Amazon Rainforest … , (it) ____. → chỗ trống cần là mệnh đề/ cụm bổ sung trực tiếp cho “biodiversity”.
Nội dung cần điền phải là V (động từ) diễn tả “biodiversity” = có/bao gồm nhiều loài.
Step 2: Compare options
❌ A. consists of many species of animals, plants, and insects => Sai collocation: consist of thường dùng cho “cấu tạo gồm”, không tự nhiên khi nói về biodiversity (đa dạng sinh học).
✅ B. includes many species of animals, plants, and insects => Đúng: includes là động từ diễn tả “đa dạng sinh học = bao gồm nhiều loài”, khớp với dự đoán.
❌ C. which includes many species of animals, plants, and insects => Sai cấu trúc: thêm which tạo mệnh đề quan hệ sau dấu phẩy không cần thiết; ở đây chỉ cần cụm bổ sung trực tiếp.
❌ D. in which many species of animals, plants, and insects => Sai ngữ pháp: in which mở đầu mệnh đề quan hệ nhưng thiếu động từ chính (ví dụ: live/exist/are found).
