Chapter 4 Language 导学案学习目标：1. 理解祈使句(imperative sentences)的意义、特点，并会运用祈使句的两大形式。2. 掌握基数词、序数词。3. 算术式的表达（一） Imperative sentences (祈使句) Look at the following imperative sentences:Be quiet!Please have a seat.David, pay attention.Dont be afraid.Dont be late.Do not make a noise, please.1. 意义：表示请求、命令或建议的句子。2. 特点：祈使句的主语一般为第二人称，但往往省去不用。3. 形式：肯定句形式：_ + 其他成分。否定句形式：_+_ + 其他成分。4. 注意：为使语气委婉，通常将祈使句与please连用。例如:Please cut me a piece of cake. 请给我切一块蛋糕。有时为了指明向谁提出请求或命令，可以加称呼语。例如:Mike, listen to me! 迈克，你听我说! 祈使句有一常用句型：Let + 主语+动词原形+其他成分。F.g: Let us go home! Let me help you! Lets start here!用英语描述算式时，我们用祈使句。这些祈使句也表示加、减、乘、除的动词开头，但要注意每个动词各自的习惯搭配。如:Subtract 4 from 8. (8-4) / Multiply 2 by 6.
