英语句型转换点拔与训练 一、肯定句变否定句的技巧 　　1.动词后直接加not。原句中含有be动词(am, is, are, was, were) 和助动词(have, has, had) 和情态动词(can, shall, will, may, should, would, might, had better等)时，要在动词后直接加not。如： 　　His mother has already called the police for help. (乌鲁木齐市中考题) 　　His mother ______ called the police for help ______. (答案：hasn’t, yet) 　　2.原句中没有be动词，助动词或情态动词时，要在行为动词前加助动词(do, does, did)与否定副词not的缩写形式。另外，还需要将原句子中的some改为any； too改either；already改为yet。还需要分清do, have等是实义动词还是助动词。如： 　　The old man hurt his leg last Wednesday. (西宁市中考题) 　　The old man ______ ______ his leg last Wednesday. (答案：didn’t hurt) 　　3.原句中含有every, everything, all, both等不定代词或both…and…, a lot of 等短语时，与否定副词not连用属部分否定。把这些不定代词变成neither, none, no one或把both…and…变成neither…nor…时，才是全部否定。如： 　　 Both Joy and Sam like singing Beijing Opera. (新疆中考题) 　　______ Joy ______ Sam likes singing Beijing Opera.(答案：Neither, nor) 　　4.在含有宾语从句的主从复合句中，当主句的主语是第一人称，谓语动词是think时，如果要否定后面的宾语从句，习惯上否定主句的谓语动词。如： 　　 I think she will come here soon. →I don’t think she will come here soon. 二、复合句与简单句的转换技巧 　　1.含宾语从句的复合句转换为简单句 　　即将宾语从句转换成相应的短语。如： 　　We expected that you would come. 我们希望你来。 　　→We expected you to come. 我们希望你来。 　　Now tell me what I should do. 现在告诉我该怎么办。 　　→Now tell me what to do. 现在告诉我该怎么办。 　　I remember I once met her at a party. 我记得在一次晚会上见过他。 　　→I remember once meeting her at a party. 我记得在一次晚会上见过他。 　　I ask him what I shall do. 我问他该怎么办。 　　→I ask him what to do. 我问他该怎么办。 　　I can’t decide whom I should invite. 我不能决定该邀请谁。 　　→I can’t decide whom to invite. 我不能决定该邀请谁。 　　2.含状语从句的复合句转换成简单句 　　即将状语从句转换成状语短语。如： 　　He can’t come because he is ill. 他因病不能来。 　　→He can’t come because of his illness. 他因病不能来。 　　Turn off the light before you leave. 离开前请关灯。 　　→Turn off the light before leaving. 离开前请关灯。 　　He went home after he finished his work. 他做完工作后就回家了。 　　→He went home after finishing his work. 他做完工作后就回家了。 　　He was so angry that he couldn’t speak. 他气得话都说不出来。 　　→He was too angry too speak. 他气得话都说不出来。 　　He studied hard in order that he could pass the exam. 他努力学习以便能考及格。 →He studied har
