对主语提问：当主语是人时，用 “Who's＋介词短语？”；当主语是物时，用 “What's＋介词短语？”。注意：无论原句的主语是单数还是复数，对其提问时一般都用be动词的单数形式(回答时却要根据实际情况来回答)。

there be句型的特殊疑问句
【点拨】
对数量提问，一般有两种提问方式：如果主语是可数名词，无论是单数还是复数，都用“How many＋可数名词复数＋are there＋介词短语？”表示；如果主语是不可数名词，则用“How much＋不可数名词＋is there＋介词短语？”表示。

there be句型中be动词的用法
be用复数还是单，与其主语很相关。
主语单数、不可数，则用is记清楚。
倘若复数作主语，用are一定要记住。
并列结构为主语，是is是are就近取。
【点拨】
there be句型中be动词的形式要和其后的主语在人称和数上保持一致。如果句子的主语是单数可数名词或是不可数名词，be动词用“is”；如果句子的主语是复数名词，be动词就用“are”。如果有两个或两个以上的名词作主语，be动词要和最靠近它的那个主语在数上保持一致，也就是我们常说的 “就近原则”。
用be动词的适当形式填空
(1) There ________ a basketball in the box.
(2) There ________ many birds in the tree.
(3) There ________ an orange and some bananas in the basket.
(4) There ________ some bananas and an orange in the basket.
