Unit 6语法篇_熟练掌握本模块的一般过去时被动语态。 一般过去时的被动语态 基本结构 肯定式：was /were +动词的过去分词 The zipper was invented by Whitcomb Judson in 1893. 否定式:主语+was /were + not + 过去分词+ by She was not given a painting by him . 一般疑问句:Was /Were + 主语+过去分词+by ? Was the zipper invented by Whitcomb Judson in 1893? 特殊疑问句:特殊疑问词+was/were + 过去分词+by Who was it/were they invented by? When was tea first drunk?When was tea brought to other countries? How was the cat found?主动变被动的方法 第一步：把主动语态的宾语变为被动语态的主语。 第二步：把谓语变成被动结构（be+过去分词）。（根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式）。 第三步：把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。如： All the people laughed at him. He was laughed at by all people. They make the bikes in the factory. The bikes are made by them in the factory.口诀：宾变主，主变宾，谓变be done ，时不变，数格必须随被变。（ ）1.

Was a car invented _ March 4, 1876?A. on B. in C. at D. of解析：1. 介词短语of all games是表示“范围”的，在一定的范围内作比较，是用形容词的最高级。interesting是多音节的形容词，所以它的最高级是用the most interesting。故选B。2. just now的意思是“刚才”，可以判断是过去时， blackboard不能执行后面的动作clean，所以用被动语态，表示主语是动作的承受者，故用一般过去时的被动语态。故选D。3. 本句考查enough的用法。enough作副词修饰形容词的时候，放在形容词的后面；enough作形容词修饰名词的时候，放在名词的前面。第一个空是用enough修饰形容词big，所以用big enough；第二个空用enough修饰后面的名词，所以用enough money。故选B。4. 本句为宾语从句，从句应用陈述句语序，又是被动语态。故选D.5. 具体在哪天，介词用on。故选A。基础演练一. 根据句意及括号内所给动词的提示填空。1.
