Chú ý sự khác nhau giữa thì quá khứ đơn và thì hiện tại hoàn thành. Quan sát hai ví dụ dưới đây: 1) I ate lunch 30 minutes ago 2) I have eaten lunch Trong ví dụ 1) động từ được chia ở quá khứ đơn (ate) và trong câu có từ ago cho biết thời gian ăn trưa là cách đây 30 phút (30 minutes ago). Trong ví dụ 2) động từ được chia ở thì hiện tại hoàn thành (have eaten) và trong câu không có từ cho biết thời gian ăn trưa là lúc nào. when (What time) did you eat lunch? --> 30 minutes ago --> I ate lunch 30 minutes ago(câu hoàn chỉnh) Mục đích của người đặt câu hỏi là muốn biết ”bạnđã ăn trưa chưa”, chứ không quan tâm đến việc bạn ăn lúc nào.
