专题15 中考无忧 句型转换在手 一、考点分析： 1. 肯定句变否定句和否定句 常考的考点：have 、do句型 2. 反义疑问句 常考的考点：带有否定副词的句子。 3. 主动句变被动语态 常考的考点：一般现在时、一般过去时、以及含有情态动词的被动语态 4. 同义句转换 常考的考点：这里对于学生是难点，主要考考纲的近义短语、常考的初中句型，本次的讲解重点。 5. 对划线部分提问 常考的考点：how long/soon/ far, how much/ many的区别和联系。 6. 肯定句改为感叹句 常考的考点：近年来考的比较少了，how/what 的修饰用法。 7. 两句子合并为一句，复合句变为简单句 常考的考点：结构状语从句，宾语从句的使用。注意改写句子的细节问题。 二．解题方法： 1. 仔细阅读整个句子，看清要求。 2．改疑问、否定、反意问句时看清时态，注意动词形式的变化。要注意几个动词过去式和原形相同的词，如：cost, read, set, put, let, fit, cut等。 3. 改被动语态的句子要注意时态、be动词的单复数以及动词过去分词的正确拼写。 4. 将两句简单句合并为一句要考虑连接成分，根据题干的语法及提供的成分答题。 5. 保持句意基本不变考察的是同一意思的多种表达，可以从同义、反义词或词组和不同句式等方面考虑。 6. 改宾语从句要注意连接词和主从句时态的一致。 考点 易错点 句型转换 1.不规则动词的过去式和原型一样的动词的时态的判断； 2.How long和how soon的用法区分； 3.同义句的转换（考纲要求的词组和常考句子）； 4.复合句尤其是宾语从句和简单句的转换； 5.反义疑问句中注意否定副词，特殊的反义疑问句用法； 高频考点 1.表结果so….that +句子= too …    (adj) to do= not …(adj反义词) enough to do He is so weak that he can’t play football. = He is___ weak ____play football. = He is not _____ ____ to play football. 2. so that….=in order to do /in order that= so as to do=to do =for doing He got up early so that he could catch the early bus. =He got up early to catch the early bus. =He got up early so as to catch the early bus. 3. if not =unless She won’t improve her handwriting if she doesn’t have enough practice. =She won’t improve her handwriting unless she has enough practice. 4. did sth… after/when=didn’t do until They left the place after they were 8. =They didn’t leave the place until they were 8. 5. 四个花费 人 + spend + 钱/ 时 + (in)doing sth /on sth。 It + takes + （人）+ 时间  + to do sth 物 + cost + （人）+ 钱  + to do sth　  人 + pay +  钱  + to sb/ for sth　 6. be held= take place举办   7. 现在完成时中瞬间动词转换为延续性动词，如 : join ---- have been in became a lawyer--- have been a lawyer---have worked as a lawyer 8. used to do sth = often/usually did sth = did sth … in the past 9.　high=in height  EG: It is 10 meters in height.
