如果陳述部分是there be存在句,附加疑問句部分的主語也應該用there
例如:
There are some books, aren’t there? 有一些書,不是嗎
如果陳述部分中帶有否定詞或半否定詞,如never,hardly,scarcely,seldom,no,none,no one,rarely,nowhere,nothing,nobody,few,little等,附加疑問句的謂語要用肯定形式
例如:
There are rarely extremes of cold or heat in Britain, are there 英國很少出現嚴寒或酷暑天氣,是嗎
There  is  little  water,is  there?
當陳述句是表示存在的句子時,簡短問句用there 作形式主語。
例如:
There isn’t a book on the table, is there?
There’s something wrong, isn’t there?
There won’t be any trouble, will there?
