人教版八年级上册期末复习 查缺补漏冲刺满分 (重点知识+难点易错点) 专题 15 句型转换 100 题 主动句变被动句 主动句变被动句第一步：要看时态，时态必须保持一致。第二步：把主动句的宾语改为 被动句的主语，谓语动词由主动形式改为被动形式，主动句的主语成为介词 by 的宾语， 放在句尾。 People keep sheep for producing wool. Sheep for producing wool people. 答案解析：在主动句中 people 是主语，是动词 keep 动作的执行者，sheep 就是 keep 的承 受者。在变被动语态时，把主动句中的宾语 sheep 变成被动句中的主语，主动句中的主 语变被动句的宾语，其前加介词 by。谓语动词变过去分词。故正确答案为： are，kept，by。 单数句子变复数句子 单数句子变复数句子就是把句在中的名词或代词变成复数形式。如果主语变成了复数， 相应地谓语动词也要注意其变化。如： This is an English book.（变复数句子） ___ ___ ___ English _____． 解析：主语 this 应变为 these。因此谓语动词由单数 is 变为复数 are; an 变为 some 用在肯 定句中。名词 book 由单数变为 books 复数形式。 对划线部分提问 做题步骤： 1. 把原句改为一般疑问句; 2. 根据划线部分内容确定相对应的特殊疑问词并放于句首； 3. 省略划线部分（若划线部分是动名词、动词或动词词组则不能省略，要用 doing 或 do 代替划线部分），其余部分照抄。 若句子中有 some 要改为 any，第一人称要改为第二人称。 （ 句 尾 问 号 别 掉 哦 ~ ） Tim looks like his father. ____ _____ Tim _____ like? 解析：在原句中 look 是系动词，his father 指人做 look 的表语，对其提问故用 who。语 序为一般疑问句语序。根据时态是现在时因此助动词用 does，系动词 looks 变为原形 look.正确答案为：Who; does ;look. 同 义 句 的 相 互 转 换 这是句子改写的一种重要形式，它涉及面广，语言点多，方式灵活，是中考命题的热 点。同义句的相互转换除了考查主动句与被动句，复合句与简单句之间的转换，直接引 语变间接引语外，还有一些词或短语的替换，仅仅通过替换几个词或短语，而使句子意 思不变，就能达到异曲同工之妙。 (1) The snow was heavy last night.（改写同义句） It snowed heavily last night. 思路解析：在（1）中 snow 是名词在句中做主语，was 是 be 动词后跟形容词做表语。 在（2）中 snow 是谓语动词，动词用副词来修饰。在本题中 snow 是多义词。 肯定句变否定句 　　A. 含有 be 动词（am/is/are）或情态动词(can/must...)的句子，直接在 be 动词或情态 动词后加上 not。 　　B. 含有实义动词（大部分动词）的句子：如果句子主语是第三人称单数，在实义动 词前加上 doesn’t，动词还原；如果句子主语不是第三人称单数，在实义动词前加上 don’t。 肯定句变否定句时，如果肯定句中有 some，要把 some 改为 any。 1．I did my homework yesterday.(改为否定句) I_____ ______ my homework yesterday. 2．Vera visited the Great Wall last Sunday.(改为一般疑问句) ______Vera _____ the Great Wall last Sunday? 3．She went to New York on vacation.(就划线部分提问) _______ did she ______ on vacation? 4．He ate nothing for breakfast.(改为同义句) He _____ ______ _________ for breakfast. 5．He didn’t go to school because he was ill.（改为同义句) He didn’t go to school _______ _______ his illness. 6．Mary visited her aunt last weekend.
