Giải thích chi tiết
✅ Đáp án: as many as 30 percent of people have eye problems as a result of working on computers
🔎 Lí do: ✔ Phân tích ngữ cảnh: câu trước nói “the problems become worse the longer you spend in front of a screen” → ý chính là càng dùng máy tính lâu, mắt càng dễ bị tổn hại. → Câu sau “Experts have estimated that (10) ________” cần một kết quả thống kê để chứng minh mức độ phổ biến của vấn đề này.
✔ Câu hoàn chỉnh: “Experts have estimated that as many as 30 percent of people have eye problems as a result of working on computers.”
“as many as 30 percent of people” = có tới 30% người → nhấn mạnh tỉ lệ cao, phù hợp với văn phong khoa học mô tả ảnh hưởng nghiêm trọng.
“have eye problems as a result of working on computers” → nêu rõ nguyên nhân – kết quả (do làm việc với máy tính). → Các chuyên gia ước tính rằng có tới 30% người bị vấn đề về mắt do làm việc với máy tính.
🚨 Những đáp án còn lại thì sao? ❌ having eye problems often leads to 30 per cent of people who want to work on computers: sai logic — “gặp vấn đề về mắt” không thể “dẫn đến 30% người muốn làm việc trên máy tính”. ❌ many people with eye problems spend 30 per cent of time each day working on computers: sai trọng tâm — câu này nói về thời gian làm việc, không phải tỉ lệ người bị ảnh hưởng. ❌ 30 per cent of people working on computers don't need to have their eyes checked annually: trái nghĩa với ý cảnh báo — văn bản nhấn mạnh vấn đề mắt tăng, không phải “không cần kiểm tra”.
