She found herself worked to death.这句话怎么理解啊 ,为什么用worked而不用wor She was playing herself because to them.这句话中为什么用because? He worked himself to death.解释下work的用法 she worked very hard 这句话里的worked是名词还是动词?如果是动词,是不是应该用副词来修饰动词? While I worked in the USA=( )( ) in the USA 中为什么前面while后用wor He’s worked there for all his life.这句话正确吗?worked前面为什么加be? 下面这句话为什么用to use?而不用using work on it had begun before she left.这里为什么不用worked 不是过去发生的嘛 为什么这个句子用until不用when 并翻译until recently,Anna worked as a teach (when i arrived,i found the door closed.)这句话为什么要用closed而不用cl She worked hard to earn her music diploma. She ought to have worked hard.正确吗
