Explanation1.指示代词 (1)在句子中，指示代词可以充当主语、定语、 宾语或表语。如： This is a pear. (作主语) 这是一个梨。

These video clips are very interesting andthose ones are not. (作定语)

这些光碟很有趣, 那些没意思。I like this very much. (作宾语) 我很喜欢这个。 Oh, it’s not that. (作表语) 哦, 不是那个。

(2)学习指示代词, 应注意以下几点: ①this与is, these与are没有缩写形式。 This is a Chinese car. 这是一辆国产轿车。 ②指示代词作主语指物并用于问句中 时, 回答一般用it代替this和that, they代替these和those。如：

--Is that a ruler? 那是尺子吗？ --No, it isn’t. It’s a pen. 不, 不是。是钢笔。 --Are these your books? 这些是你的书吗? --Yes, they are. 是的。

2. no和not 二者都是“不”的意思，但用法不同。前者可 单独使用，用于回答一般疑问句，反义词为 yes;后者不能单独使用，要和be动词、助动 词等一起构成否定句。

如：--Is this your pencil?

这是你的铅笔吗?--No, it isn’t. 不, 不是。 It is not my book. 这不是我的书。
