人教版九年级全册英语 Unit 6 When was it invented?单元语法及习题（含答案）

九年级英语 Unit 6 When was it invented 单元语法
一般过去时的被动语态
被动语态在本单元用于强调动作的承受者（即发明物）及发明时间，句型结构为：“主语（发明物） + was/were + 过去分词 (+ by + 发明者) + 时间状语”。
示例与解析：
基础结构：
The telephone was invented by Alexander Graham Bell in 1876.
（电话由亚历山大·格拉汉姆·贝尔于1876年发明。）
主语 The telephone 是动作的承受者，was invented 为被动语态结构，by Alexander Graham Bell 说明发明者，in 1876 为时间状语。
时间状语的多样化：
The light bulb was invented in the 19th century.
（电灯泡发明于19世纪。）
Paper was first created in China around 105 AD.
（纸张最早于公元105年左右在中国被制造出来。）
When was the computer invented
（计算机是什么时候发明的？）
（二）特殊疑问词引导的一般过去时被动语态疑问句
特殊疑问词引导的一般过去时被动语态疑问句，用于询问过去被动动作的相关信息，如时间、地点、执行者等，在本单元中常用于对发明创造等事件的具体细节进行提问。
询问时间：用 “when” 引导，结构为 “When + was/were + 主语 + 及物动词的过去分词？”。例如，“When was the computer invented （电脑是什么时候发明的？）”，这类问句旨在了解某个发明或事物在过去被创造或发生的具体时间点。回答时通常会给出具体的年份、年代等时间信息，如 “It was invented in the 1940s.（它是在 20 世纪 40 年代发明的）” 。通过这种询问方式，能更准确地掌握历史事件或发明创造的时间脉络。
询问地点：由 “where” 引导，结构是 “Where + was/were + 主语 + 及物动词的过去分词？”。例如，“Where was the first car made （第一辆汽车是在哪里制造的？）”，此结构用于探究过去某个事物的制造、生产地点。答案可能是具体的城市、国家等地点，如 “It was made in Germany.（它是在德国制造的）” ，帮助人们了解事物的起源地或产生地点。
询问执行者：用 “who” 或 “whom” 引导（“whom” 在口语中较少使用，常被 “who” 替代），结构为 “Who + was/were + 主语 + 及物动词的过去分词 + by ”（“by” 引出动作执行者）。例如，“Who was the TV invented by （电视是由谁发明的？）”，这类问题用于明确过去某个被动动作的实施者。回答时会提及具体的人物，如 “It was invented by John Logie Baird.（它是由约翰 洛吉 贝尔德发明的）” ，让人们知晓发明创造背后的关键人物。
（三）现在完成时的被动语态与一般过去时的被动语态对比
现在完成时的被动语态和一般过去时的被动语态在含义和用法上存在一定区别，在本单元中，正确区分两者有助于更准确地描述事物的状态和动作发生的时间关系。
现在完成时的被动语态结构与含义：现在完成时的被动语态结构为 “have/has been + 及物动词的过去分词”，强调过去发生的被动动作对现在造成的影响或结果，或者表示过去开始的被动动作一直持续到现在。例如，“The book has been translated into many languages.（这本书已经被翻译成多种语言）”，此句表明翻译这本书的动作在过去发生，其结果是现在这本书有多种语言版本，对现在的书籍传播和使用产生了影响。
与一般过去时被动语态的区别：一般过去时的被动语态仅表示过去某个时间发生的被动动作，与现在没有直接关联；而现在完成时的被动语态侧重于过去动作对现在的影响或持续到现在的状态。以 “The house was built in 1990.（这所房子建于 1990 年）” 和 “The house has been lived in for 30 years.（这所房子已经被居住了 30 年）” 为例，第一句只是单纯陈述房子在 1990 年被建造的过去事实；第二句则强调从过去到现在这所房子一直处于被居住的状态，突出对现在的影响，即房子现在有人居住且已经持续了 30 年。在实际使用中，要根据具体语境和表达意图，准确选择使用现在完成时的被动语态还是一般过去时的被动语态。
