2.當陳述部分的主語是指示代詞this, that, these, those時，附加疑問句的主語不再用指示代詞，而要用it或they。	That isn’t your dictionary, is it? 這不是你的字典，是嗎？ These are interesting stories, aren’t they? 這些故事很有趣，不是嗎？
3.當陳述部分是“there be+主語+其他”結(jié)構(gòu)時，附加疑問句用“be (not) there”結(jié)構(gòu)。	There is a book on the desk, isn’t there ? 桌子上有本書，是嗎？ There are not any pens in the box, are there? 盒子里沒筆了，是嗎？
