Answers: 1.library; 2.restaurant; 3. post office; 4. supermarket; 5. park1.____ 2.____ there be结构表示“某处有某人/物”，其中be动词和后面的主语保持数的一致。 在一般现在时中，若主语是单数名词或不可数名词时，be动词用 is； 若主语是可数名词复数，be动词则用are。 若有两个（以上）并列主语时，使用“就近原则”，即be动词的形式要与离其最近的一个主语在数上保持一致。there be结构的三种句式变化：（1）肯定句：There be + 主语 + 地点。（2）否定句：There be + not + 主语 + 地点。（3）一般疑问句：Be + there + 主语 + 地点？（注意其答语仍要用there, 如一般现在时的肯定答语是Yes, there is / are; 否定答语是No, there isn’t / aren’t。）Grammar Focus巧记一般现在时的there be结构：There be 句型不一般，主语跟在be后边。 be可变为 isare, there永远不变化， 单数主语用 is，复数主语须用 are |
