Read the dialogue between the captain and the soldier from the story of the Trojan Horse. Pay attention to the tenses of the verbs in bold. Soldier: Captain! Captain! The Greeks have gone. They left last night. Captain: Great! We have finally won! I have waited so long for this moment. Soldier: Look! Our men have found something unusual. The Greeks left a huge wooden horse near the city. Can you see it outside the main gate The Greeks did not take it with them. We use the present perfect to talk about past events with a connection to the present. We use the simple past to talk about a completed action in the past. 1.The Greeks have gone. They left last night 2.We have finally won! I have waited so long for this moment. 3.Our men have found something unusual. The Greeks left a huge wooden horse near the city 现在完成时与一般过去时 一般过去时和现在完成时所表示的动作都发生在过去，但要注 意以下区别： 现在完成时强调过去发生的动作对现在的影响或过去开始发生 一直持续到现在的动作。与特征词since, for, already, yet, ever, never, so far, up to now等连用。如： — Would you like to see the film with me 你想和我一起去看这部电影吗？ — No. I’ve seen it twice. 不了，我已看了两遍了。（过去已看过，所以现在不想看了） 2 一般过去时强调动作在过去发生，与现在无关。与具体的表示过去时间的状语（如：yesterday, last night）连用。如： I saw the film last night. 我昨晚看了那部电影。（仅是对过去事情的陈述） 区别 结构 常见连用词 现在完成时 （表示过去发生的动作对现在造成的影响或结果） have / has +过去分词 haven’t / hasn’t + ... ...
