英语语法:过去完成时 详细解析 过去完成时的形式 过去完成时的形式为 had/hadn’t + 动词的过去分词: He hadn’t been there before. 他以前没有去过那里。 I had never worked. 我从来没有工作过。 所有人称的过去完成时都是一样的。 I/you/he/she/it/we/they had left when I arrived 可以把 had 缩写成 ‘d。 He finished the report after he’d talked to the boss. 和老板谈完后,他完成了报告。 过去完成时的用法 当说明过去并且想要说明比过去更早发生的事件时要用过去完成时。 I went to the party after I had completed the task. 完成任务后我去参加了晚会。 Yesterday my dad told me that he had seen you in the zoo. 昨天我爸爸告诉我他在动物园见过你。 过去完成时 or 过去简单式? 过去简单式可以以时间先后描述一系列过去的事件,而过去完成时可以清楚说明其中有个事件在此过去更早已经发生。比较两个句子: When I returned home, she washed the dishes.当我回到家时,她洗了碗。 (=我回家后她洗了碗。) When I returned home, she had already washed the dishes.当我回到家时,她已经洗好了碗。 (=她在我回家之前洗了碗。) 注意这些常见的错误! 要记得 would 后面要加不定式而 had 后面要加过去分词。 I’d like to go to the beach. (= would) 我想去海滩。 I found that he’d completed his homework. (= had) 我发现他已经完成了作业。 #英语 #英语语法 #英语口语 #英语学习#英语启蒙

语法:现在完成时的结构形式及用法 一.现在完成时的形式 现在完成时的形成为动词 have 加上动词的过去分词。规则动词的过去分词和过去式的形式一样(-ed),不规则动词的形式则是像: see->seen。 I have seen her. I have not seen her. Have you seen her. Yes, I have/haven’t. 现在完成时的用法: 现在完成时通常表达与现在有关连的过去事件,例如新闻或过去的经历。现在完成时也可以表示在过去开始的某个情况到现在仍然持续,. **常搭配 Just, yet, already . She has just landed at the airport. 她刚刚降落在机场。 I can’t get on the bus, I’ve just lost my ticket. 我不能上公车,我刚刚丢了票. **常搭配 Never, ever, before 在询问他人的生活经历时通常会使用ever。 Have you ever tasted this before? 你以前尝过这个吗? Have you ever been to Europe? 你去过欧洲吗? **常搭配 how long, for, since,用于未完成的动作 现在完成时加上 how long, for, since 来表示过去开始的行为或情况到现在仍然持续或是正确的。 I’ve been at school since 7 o’clock in the morning. 我从早上 7 点就在学校了。 (我早上在学校,我目前还在学校) She has watched this show for three months. 她已经看了这个节目三个月了。 (她看了三个月的节目,目前还在看。) 注意这些常见的错误! 在表达过去开始而现在仍然为持续的行为或情况时要用现在完成时,而非现在简单式。 They‘ve worked together since last month. 从上个月开始,他们就开始合作了。 (不能说 They worked together since last month.) ago 不能与现在完成时一起使用。 #英语 #中考 #英语口语 #英语学习 #知识点总结
