Is that a banana? 结论:肯定句变为一般疑问句,只需把be动词(am, is , are)提前。 1、This is 不能缩写, 而That is可以缩写。如: This is a book. That’s a bike. 这是一本书。那是 一辆自行车。 2、打电话时,介绍自己用this, 询问对方用that。 如: —Hello! Is that Miss Liu? 喂,是刘小姐吗? —Yes, this is. Who’s that? 是的,我是,你是谁? 注意:虽然汉语中使用“我”和“你”,但英语中打电 话时绝不可以说:I am…, Are you…?/Who are you? 注意事项: these是this的复数形式,指时间,距离较近的或下面要提 到的人或事; 复数: What are these?

These are bananas. That is a bird. Those are birds. 如不特指远近,所有句子中的this,that都可 以用it代替。 Eg: what is it? -It’s cat. 如不特指远近,所有句子中的these,those都 可以用they代替。 Eg: what are they? -They are bananas. 需要注意的是: 单数名词和复数名词: 单数名词: shirt , dress , umbrella , hat , desk , skirt . 复数名词(成对出现):troures pants , shoes , socks , shorts , gloves , sunglasses , jeans.
