     In 1961, a man found a strange cat on his farm in Scotland. The cat's ears were folded, bent forward,

on its head. In fact, this was a new kind of cat. People named it the "Scottish Fold (苏格兰折耳猫)".

     The Scottish Fold has a round head and large eyes. Its neck and legs are short, which makes it look very

cute. Interestingly, all the Scottish Folds are born with straight and unfolded ears. And when they are growing

up day by day, some cats' ears will begin to fold. So, the Scottish Fold comes in two types: folded ears and

straight ears.

     Besides, there is a nickname for the Scottish Fold. It is the "Messenger of Peace". Why? Because the Folds

are sweet and friendly animals. They can get along well with other cats. And unlike some other cats, they can

even get along well with dogs! In many different environments, such as at a noisy house, or in a cat show,

you can see them playing with other animals happily. Well, when you come to a new school, do you think it's

difficult to adapt to the new environment? Perhaps you can learn from the Scottish Fold. That is: always be

sweet and friendly to others.

试题五（共15分）阅读下列说明，回答问题1至问题3，将解答填入答题纸的对应栏内。【说明】某停车场有多个入口和出口，车辆进入时从入口处由系统查询可用的停车位，从出口驶出时系统将其刚使用的车位标记为空车位。假设实现停车场管理的伪指令如表5-1所示：

根据上述描述，在入口处的伪代码程序为：x = Get();IF x =NULL THEN return 0;Writ(x, 1);

【问题3】（4分）若停车位表的关系模式为：park(parkno, isused)，其中parkno为停车位号，isused为停车位标志，0为空，1为非空。下面是用E-SQL实现的查询空车位的函数Get()，请补全空缺处的代码。SET TRANSACTION ISOLATION LEVEL SERIALIZABLEEXEC SQL DECLARE getblk CURSOR FOR（a）;EXEC SQL OPEN getblk ;EXEC SQL FETCH getblk INTO :Hparkno; // Hparkno为已声明的主变量IF SQLCA.sqlcode = 100 THENEXEC SQL CLOSE getblk ;Return NULL;ELSE（b）;END IF试题中通用的表示规则关于概念模型、关系模式的标记，试题中若无特殊声明，将使用如下的通用标记规则。1．概念模型的标记规则分别如图1、图2和图3所示。其中：（1）实体类型用长方形表示，弱实体用双线长方形表示。长方形内为实体类型名称。（2）实体类型间的联系用菱形表示，弱联系用双线菱形表示，菱形内写上联系的名称，并在联系与实体间的连线上注明联系的类型。

（3）超类型和子类型之间的联系，从超类型到子类型之间画连线，连线上加注小圆圈，子类型加双线竖框。

（4）实体和联系的属性用椭圆表示，并用直线将属性与其所属的实体或联系连接起来。

2．关系模式的标记规则如下：关系名（属性名1，属性名2，… ，属性名n）其中：（1）若该属性仅为主键属性，则该属性名下画实下划线；（2）若该属性仅是外键属性，则该属性名下画虚下划线；（3）若该属性既是主键属性，又是外键属性，则在该属性名下面画实下划线和虚下划线。
