Present Perfect Tense Game: 1.Have you seen my food? 解析：此句时态是现在完成时疑问形式。现在完成时由“主语+have/has +动词过去分词形式”构成。它的要义在于表达过去已经发生的事情对现在造成的某种影响，或者，强调过去发生的事情一直持续到现在的状态。 它的否定形式为：haven’t /hasn’t +动词过去分词 它的疑问形式：把have或者 has 提到相应主语的前面。 Language points For example: A: Have you studied English for ten years? B: Yes, I have. And you? A: No, I haven’t. B: Then how many years have you learnt English? A:I have learnt it for eight years. ★ haven’t = have not hasn’t = has not I’ve = I have You’ve = You have 2. I've just eaten it. 我刚才把它吃了。 just adv. 意为“刚才”常与完成时连用。 他们刚刚到达。 They have just arrived. 注意：just now 意为“刚才”，相当于“a moment ago”通常与一般过去时连用。 我刚才去了图书馆。 I went to the library just now. 3.You used to share food with me! 你过去常与我分享食物！ used to do sth. 意为“过去经常做某事，以前常常做某事”，表示过去的习惯。本身已是过去时态，没有人称和数的变化，暗含现在已不再如此。 他的父母过去住在乡下。 His parents used to live in the countryside. be used to doing sth.习惯于做某事 我父亲习惯晚饭后读报。 My father is used to reading newspapers after dinner. 4.past n. 意为“过去”。 她正在回忆她的过去。 She is thinking of her past. past adj.意为“过去的” in the past 过去 in the past few years 在过去的几年中 —What do you think of your junior school life? —It some sweet memories in my heart in the past three years.
