把含有some的肯定句变成否定句或疑问句时,要用any; 例如:There are some apples in the bag. 否定:There aren't any apples in the bag.
对there be句型的一般疑问句作简略回答时,用there; 例如: Are there any apples in the bag? Yes,there are. No,there aren't.
若对there be中的主语进行提问,无论主语是单数还是复数, 都习惯用What's+地点状语;
there be结构的陈述句变成反义疑问句时,附加句的主语应用there; 例如: There is a beautiful flower on the table,isn't there? There aren't any people in the room,are there?
