I finally found my lost coupon, but there were no stocks left at the greengrocer’s.

14/25

I had found my lost coupon before there were no stocks left at the greengrocer’s.

When there no stocks left at the greengrocer’s, I was finding my lost coupon.

There were no stocks left at the greengrocer’s by the time I had finally found my lost coupon.

By the time I found my lost coupon, there had been no stocks left at the greengrocer’s.

Giải thích

Gốc: I finally found my lost coupon, but there were no stocks left at the greengrocer’s.

(Cuối cùng tôi cũng tìm thấy phiếu giảm giá bị mất, nhưng cửa hàng rau quả đã hết hàng.)

→ Viết lại bằng: By the time + S + V2/ed, S + had + V3/ed

Chọn D. By the time I found my lost coupon, there had been no stocks left at the greengrocer’s.

Dịch: Đến lúc tôi tìm được phiếu giảm giá bị mất thì ở cửa hàng rau quả đã hết hàng.

Các đáp án sai:

A: tìm được trước khi hết hàng → sai nghĩa.

B: sai ngữ pháp “When there no…” và “was finding” sai thì

C: “There were … by the time I had found …” → sai phối thì (“had been” mới hợp với “by the time”).
