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.

Do you know who did it?A. cleaned B. was cleaning C. has cleaned D. was cleaned( )3.That house is not , so we have to buy it.A. enough big; enough money B. big enough;enough moneyC. enough big; money enough D. much big; many money( )4.

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.
