5、 一般疑问句在句子中用提问的方式提供一些信息，要求对方用 Yes 或 No 回答的疑问句。朗读一般疑问句时用升调，对其回答时用降调。本单元我们学习的是含有be动词的一般疑问句。语法概述Presentation1) 结构：Be动词(am/is/are)+主语+其他?（Be动词要和主语的人称和数保持一致。）2) 肯定回答：Yes, 主语+be动词(am/is/are). 主语和be动词不能缩写。3) 否定回答：No, 主语+be动词(am/is/are)+not. 通常is、 are和not要缩写， 但am和not不能缩写。4)如果一般疑问句主语是this、that、these或those，回答时

6、用it指代this或that；用they指代these或those。Is this your pen? 这是你的钢笔吗？ Yes, it is. 是的，它是。Are these your books? 这些是你的书吗？ No, they arent. 不，它们不是。不可以缩写成its含be动词的肯定句变一般疑问句，可以采用“一提、二变、三问号”的方法。一提：be动词提到句首， 且首字母大写。二变：把原主语的首字母变成小写； 如果原主语是第一人称，则应把第一人称变为第二人称， be动词也作相应变化；如果有形容词性物主代词my，也应改为your。三问号：将句末的句点改为问号。He is a stu

His is on t
