He does speak good English. 四、特殊注意事项 1、助动词的省略: 在简单句的肯定句中不使用do助动词 错误:I do like apples. 正确:I like apples.(除非特别强调) 2、助动词后的动词形式: be助动词后接现在分词(进行时)或过去分词(被动语态) have助动词后接过去分词 do助动词后接动词原形 3、多个助动词连用: 完成进行时:have + been + 现在分词 I have been waiting for an hour. 被动语态的完成时:have + been + 过去分词 The work has been finished. 4、助动词的缩略形式: is → 's are → 're have → 've has → 's had → 'd will → 'll would → 'd 五、常见错误分析 1、助动词重复使用: 错误:Does he likes music 正确:Does he like music 2、时态混淆: 错误:She is went to school. 正确:She went to school. / She is going to school. 3、被动语态错误: 错误:The book was write by him. 正确:The book was written by him. 4、否定形式错误: 错误:I not like swimming. 正确:I don't like swimming. 1. —Who____drawing —Sandy and I ____.
