5、为：“Be动词主语(指示代词)其他？”。当主语是指示代词this/that，作简略回答时，要用it代替；当主语是指示代词these/those，作简略回答时，要用they代替。如：Is this his book？这是他的书吗？Yes，it is.是，它是。Are these your books？这些是你的书吗？No，they arent.不，它们不是。【注意】第一人称要进行人称转换。如：This is my pencil.这是我的铅笔。(改为一般疑问句)Is this your pencil？这是你的铅笔吗？名词性物主代词：在英语中，物主代词是表示所有关系的代词，分为形容词性物主代词(第一

7、ver there.(YoursYour books)这些书是他的，你的(书)在那边。与形容词性物主代词之间的关系：名词性物主代词相应的形容词性物主代词名词如：This is my bike.That is yours.(yoursyour bike)这是我的自行车，那是你的(自行车)。 结构：“be + 主语 + 其他部分？” 意思：吗？ 答句：Yes/No开头回答。 注意：肯定回答不可以缩写 朗读：一般疑问句用升调 例如：Is it your schoolbag?
