Past perfect simple (had + V3)
Hình thức: had + past participle dùng cho mọi chủ ngữ (I'd finished, they had left). Cách dùng: diễn tả hành động hoặc trạng thái xảy ra trước một mốc thời gian trong quá khứ, hoặc nhấn mạnh kết quả tại mốc đó. Ví dụ: By the time I arrived, everyone had left.
Dấu hiệu: by, by the time, before, after, just, when. Chú ý phân biệt: "The lesson started when I arrived" (tôi đến rồi bài học mới bắt đầu) khác với "The lesson had started when I arrived" (bài học đã bắt đầu trước khi tôi đến).
Past perfect continuous (had + been + V-ing)
Hình thức: had + been + V-ing. Cách dùng: hành động kéo dài đến, hoặc vừa dừng ngay trước một mốc trong quá khứ; nhấn mạnh quá trình và khoảng thời gian. Ví dụ: She was tired because she'd been running.
Dấu hiệu: for, since, before, all day/night. Phân biệt: dạng đơn nhấn mạnh kết quả (She'd written it = đã xong), dạng tiếp diễn nhấn mạnh hành động và thời gian (She'd been writing it = đang viết, chưa xong).
