课件20张PPT。完成句子学习目标
1、熟练掌握三种简单的基本句型的句型转换
2、能根据汉语提示补全英语句子要点梳理:从近几年重庆市中考英语来看,完成句子有两种题型:一是句型转换;二是句子翻译。
句型转换
句型转换题主要有两大类:一是基本句式的转换;二是同义句的转换。基本句式的转换主要是指:肯定句、否定句、一般疑问句、特殊疑问句等的转换。(一)肯定句、否定句、一般疑问句的转换
这三种句型的转换有共同的规律可循,有几个要点必须牢记。我们可以把各种句式归为两大类:1.含有be 动词、助动词和情态动词的句子;2.只有行为动词的句子。
第一类句子,肯定句改为否定句时,一律在be动词、助动词和情态动词后加not。改为一般疑问句时,一律将be动词、助动词和情态动词前移到句首(首字母大写)。例:将下列句子改为否定句、一般疑问句。
1.Li Ming’s father can drive a car.(情态动词)
-Li Ming’s father ______ drive a car.
-______ Li Ming’s father drive a car?
2. They are from Canada.
-They _____ _____ from Canada. ( They _____ from Canada.)
-______ they from Canada?Can’tCanarenotaren’tAre第二类句子必须借助助动词do, does。改为否定句,在行为动词前加don’t(一般现在时态,主语是除第三人称单数之外的人称和数);doesn’t(一般现在时态,主语是第三人称单数时),并把谓语动词第三人称单数形式改为动词原形 。改为一般疑问句时,在句首加Do(一般现在时态,主语是除第三人称单数之外的人称和数);或Does(一般现在时态,主语是第三人称单数时),并把谓语动词第三人称单数形式改为动词原形 。例:将下列句子改为否定句、一般疑问句。
1.The children like playing games.
-The children _____ like playing games.
-_______ the children like playing games?
2. Mary usually goes to school on foot.
-Mary _____ usually go to school on foot.
-______ Mary usually go to school on foot?don’tDodoesn’tDoes(二)特殊疑问句的转换
把句子转换成特殊疑问句,其实就是对划线部分提问、是用一个合适的疑问词去替代句中的某一部分、也是写出这个答句的问句,使之成为一个特殊问句。其方法主要是:先依据句意选择相应的疑问词和疑问句语序,句末改用问号。这时我们要注意几点:
1.选择恰当的疑问词。人、物、时间、地点、数量等分别用:who; whose; what; when; where; how; how many; how much; how old;等。2.对主语或主语的定语提问时,用陈述句语序。对定语提问时,所修饰的名词应放在疑问词后。
3.对其他成分提问,用“疑问词+一般疑问句”语序。首先要确定划线部分的“疑问词”,将相应的疑问词放在句首,其余部分改为一般疑问句的形式,就是特殊疑问句。改完后要注意检查句首的首字母大写和句尾的标点符号。例如:将下列句子就划线部分提问
(1) Meat is the tiger’ favorite food.
_____ _____ the tiger’ favorite food?
(2)These are Jane’s shoes.
______ _____ are these?
(3)This bag of rice is 30 yuan.
_____ _____ is this bag of rice?WhatiswhoseareHowmuch(三)同义句转换

10 .Please give me an orange.

在重庆市中考试题中,这类题型的要求是根据汉语提示补全英语句子,每空一词。做这类题,相对比较简单,一般是对固定短语、句型搭配和习惯用法等的考察。在解题时,要认真分析句子的特点和句型结构,根据空格所担任的句子成分和空格数目,确定适当的词(词组),并注意一些必要的词性和时态变化等。1.玛丽想试穿这件漂亮的短裙。
-Mary wants to _____ _____ the nice skirt.
