• 如果一个句子中有be的形式存在，那么这个 句子的疑问或否定形式都在be本身变化，比 如一般疑问句，只要把be动词提前，否定句 就在be后面加not就可以了。
• 另外记住some用于可数名词单数及不可数名 词，并且用于肯定句中。any用于不可数名 词，并且用于否定句和疑问句。

cold 冷的 thin 瘦的
fat
big
肥胖的
大的

practice
• 请你变换刚才的三个句型，分别改成一般 疑问句以及否定句。
• There is a tie in the box. • There are two shirts on the bed.

Key point
• 1.不管作主语的名词有多少个，be动词的数只与第一个 名词保持一致。这就是传说中的就近原则。 • There is a pen, two pencils and some books on the desk. 书桌上有一支钢笔、两支铅笔和一些书。

口诀
• There be句型不一般，主语跟在be后边。 • • • • • • be可变为is / are, there永远不变化， 单数主语用is, 复数主语要用are。 变疑问，很简单，be须大写来提前； 变否定，也轻松，be后not记心中； 肯定句中用some, 否定、疑问any用。 时间／地点是状语，句子首尾任你选。
