过去时的结构 一般过去时的结构
过去完成时的句子结构是:主语 + had + 动词的过去分词。
一、肯定句
例如:我已在妈妈回家之前完成了作业。(I had finished my homework before my mother came back.)“我”是主语,“had finished”表示过去完成时的动作,“作业”是宾语。
二、否定句
只需在had后加not。例如:我昨前还没看望过我的祖父母。(I had not visited my grandparents before yesterday.)“我”是主语,“had not visited”是否定的过去完成时动作,“祖父母”是宾语。
三、一般疑问句
将had提前。例如:你在那之前看过那部电影吗?(Had you seen that movie before?)
四、特殊疑问句
特殊疑问词 + had + 主语 + 动词的过去分词?例如:你睡觉前做了什么?(What had you done before you went to bed?)
单项选择
- 正确答案是:A。解析:根据句子结构和时间点“By the time I got to the party”,可以确定使用过去完成时,且主语为单数第一人称,助动词用had。
- 正确答案是:A。解析:根据时间点“before her mother came back”,应使用过去完成时,且主语为单数第三人称,助动词用had。
- 正确答案是:A。解析:由“before yesterday”这个时间点可知,应用过去完成时,had表示过去发生的动作已经完成。
- 正确答案是:A。解析:“when I arrived”表示过去的某个时间点,“just left”在这个时间点之前发生,所以用过去完成时had left。
- 正确答案是:A。解析:“by the end of last year”表示过去的某个时间点之前,应用过去完成时,主语为复数,但过去完成时不分人称,都用had。

My Unforgettable Experience
Last year, I had an unforgettable experience at a music festival. Before the festival, I had eagerly prepared for weeks, practicing my instrument and learning the songs I would perform. The day finally came, and I had arrived at the festival early. I had set up my equipment and was ready to perform. The crowd was excited, and I could feel their energy. As I played, I could hear the audience cheering and clapping. It was a moment I would always remember.
