句型转换 因为“had done”中的was/were是助动词，所以在进行句型转换中要注意不需要再另外借助助动词do/did/does，而是直接借用had。如： 肯定句：He had worked here for a good many years. (他在这里工作了很多年了。) 否定句：He hadn't worked here for a good many years. 一般疑问句：Had he worked here for a good many years? 特殊疑问句：How long had he worked here? (划线部分为a good many years) (责任编辑：admin) |
