仁爱2019-2020学年八年级上册期中备考--句型变化 一、肯定句改否定句 巧学妙计 句中“变色龙be”动词的,在be动词后加not; 句中有“情态动词”的(can?,should,must?,would),在情态动词后面加not; 无情无be,在动词前加don’t或doesn’t?;??? 句中动词为原形的,加don’t?. 如:?I?like?apples.?àI?don’t?like?apples.??? 句中动词为三单式的,加doesn’t,并将三单式的动词还原成原形。? 如:He?likes?apples.à?He?doesn’t?like?apples.? 时态为过去时的,要加didn’t??而且动词过去式要改为原形,? 如:I?went?to?school?yesterday?.→I?didn’t??go?to?school?yesterday?.? ④肯定句中的some在否定句中应改为any?? There?are?some?students?in?the?classroom.à? →There?are?not?any?students?in?the?classroom. 二、陈述句改一般疑问句 巧学妙计 温馨提示 在一般疑问句的肯定回答中,be动词不能用缩略形式。如: Are you Maria? 你不能回答为:Yes, I’m. 而应该回答为:Yes, I am. 2.如果句中没有be动词、助动词或情态动词,则根据谓语动词的形式借助do的相应形式放在句首。具体方法是:“一加二改三问号” ①如果谓语动词是原形或者主语是第一人称、第二人称、第三人称复数则借do; ②如果谓语动词是一般现在时第三人称单数形式,则借does; 需要注意的是,借does后,原句的谓语动词要变回原形。 例:They go to school by bike.→Do they go to school by bike? 三、划线部分提问 以下口诀要牢记 问“谁”用who; 2. 问“什么”,用what; 3.问“职业”,用what; 4.问“谁的”,用whose; 5.问“地点哪里”,用where;? 6.问“原因”,用why; 7.问“身体状况”,用how; 8.问“方式”,用how; 9.问“年龄”;用how old;问多经常,how often;问多久,用how soon/how soon?? 10.问“多少”,用how?many;? 11.问"价钱”用how much; 12.问“哪一个”,用which?; 13.问“颜色”,用what colour;? 14.问“星期”,用what day;? 对划线部分提问的程序: 一找:找特殊疑问词; 二代:用特殊疑问词代替划线部分; 三移:把特殊疑问词移到句首; 四变:未划线部分变为一般疑问句。 温馨提示 在特殊疑问句中,疑问代词属于第三人称,后面的动词通常用单数形式;如已明确所指的是单数或是复数,动词就相应的发生变化。 Who is he? 他是谁? (he是单数人称,故be动词使用is) Who are these boys? 这些男孩是谁?(these boys是复数人称,故be动词使用are) --What’s in this bag? 袋子里有什么? --Some apples.一些苹果。 (询问时,并不清楚袋子里有什么,故用is,而不是are) I. 把下列句子变为否定句: 1.
