Giải thích

Kiến thức: Mệnh đề quan hệ

Giải thích:

Đại từ quan hệ “which” có thể thay thế cho cả mệnh đề đứng trước nó, làm chủ ngữ trong mệnh đề quan hệ:

S + V, which + V + …

overconfident (adj): quá tự tin

overconfidence (n): sự quá tự tin

A. because + S + V = because of + N/Ving: bởi vì => Câu A sai.

C. Câu C sai do dùng danh từ “confidence”.

D. Cấu trúc câu chẻ: It + is + N + that + V + … => Câu D sai.

Tạm dịch: Anh ta quá tự tin, điều đó đã phá hỏng hoàn toàn kế hoạch của chúng tôi.
