12、思相反（即Yes是 “不”的意思；No是 “是”的意思）。在回答时，要注意分析上下文语境中所提供的条件。如：- Dont go out, please. Its raining heavily outside. 请不要出去。外面雨下得很大。 - Yes, I will. I have to meet my brother at the airport. 不行，我得去机场接我弟弟。 （二）易错点讲解1、放句首时，要注意Dont后面要用动词原形；2、当人称后面有标点符号时，要注意是用祈使句还是用三单。Lucy, dont be late again. Lucy, a 17-year-old gir
