新目标7上Units 1-5讲练 单词讲解1. dodo是助动词，没有实在意义，用主语是第一人称、第二人称和第三人称复数形式的句中来构成否定句和疑问句，do的第三人称单数形式是does，变成否定句时直接在do或does后加not；变成疑问句时直接将do或does移到句首。如：Do you like reading books, Millie? 米，你喜欢读书吗？My brother doesn’t have an English book. 我弟弟没有英语书。【拓展】do还可用作实义动词，即行为动词，意为：“做；干”。变成否定句时不可以直接在do或does后加not，仍然要借助助动词do或does；变成疑问句时也不能直接将do或does移到句首，而是要借助助动词do或does。如：Alan doesn’t do homework at home on Sunday. 艾伦日不在家做。Does Alan do homework at home on Sunday? 艾伦日在家做吗？【do即时】句型转换，每空一词1.
