Passage Three

More than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8.

The department gave a report to the expulsions (开除) as saying handguns accounted for 58% of the 6,093 expulsions in 1996—1997, against 7% for rifles (步枪) or shotguns and 35% for other types of firearms.

"The report is a clear sign that our nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement.

In March 1997, an 11-year old boy and a 13-year old boy using handguns and rifles shot dead four children and a teacher at a school in Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14-year old boy killed three high school students and wounded five in Kentucky.

Most of the expulsions, 56%, were from high school, 34% were from junior high schools and 9% were from elementary schools, the report said.

41. From the first paragraph we can infer that in the US schools______.

A. students enjoy shooting

B. safety is a problem

C. students are eager to be solider.

D. students can make guns.

    查询所有目前年龄在35以上(不含35岁)的职工信息(姓名、性别和年龄)的正确的命令是A) SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期)年龄FROM职工;WHERE年龄>35B) SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期)年龄FROM职工;WHERE YEAR(出生日期)>35C) SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期、年龄FROM职工:WHERE YEAR(DATE()-YEAR(出生日期>35D) SELECT姓名.性别.年龄=YEAR(DATE())-YEAR(出生日期、FROM职工:WHERE YEAR(DATE())-YEAR(出生日期)>35


    正确答案:C
    用日期型函数YEAR()来表达年龄在35岁以上这个查询条件的正确写法应该是
            YEAR(DATA())-YEAR(出生日期)>35
    其中用到了DATA()函数,先求出当前日期,再用YEARQ求出该日期表示的年份,由此可知选项A和选项B的表示方法是错误的。选项D的错误在于使用SQL进行查询时,是不能使用等号进行列的赋值操作。故选项C为正确答案。

  • 第4题:

    查询所有目前年龄在35岁以上(不含35岁)的职工信息(姓名、性别和年龄),正确的命令是

    A.SELECT 姓名,性别,YEAR(DATE())-YEAR(出生日期)AS年龄FROM职工; WHERE年龄>35

    B.SELECT 姓名,性别,YEAR(DATE())-YEAR(出生日期)AS年龄FROM 职工; WHERE YEAR(出生日期)>35

    C.SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期)AS年龄FROM 职工; WHEREYEAR(DATE())-YEAR(出生日期)>35

    D.SELECT姓名,性别,年龄:YEAR(DATE())-YEAR(出生日期)FROM 职工; WHERE YEAR(DATE())-YEAR(出生日期)>35


    正确答案:C
    解析:在SQL SELECT子句中利用AS关键字,可以重新定义字段名,但并不存储在表内,称为虚字段。在设置查询条件 时,不能根据新定义的字段名对原数据表设置查询条件。

  • 第5题:

    可以正确查询所有目前年龄在35岁以上的职工信息(姓名、性别和年龄)的SQL SELECT命令是( )。

    A.SELECT姓名,性别,YEAR(DATE)-YEAR(出生日期)年龄FROM职工; WHERE年龄>35

    B.SELECT姓名,性别;YEAR(DATE)-YEAR(出生日期)年龄FROM职工; WHERE YEAR(出生日期)>35

    C.SELECT姓名,性别,年龄=YEAR(DATE)-YEAR(出生日期)年龄FROM职工; WHERE YEAR(DATE)-YEAR(出生日期)>35

    D.SELECT姓名,性别,YEAR(DATE)-YEAR(出生日期)年龄FROM职工; WHERE YEAR(DATE)-YEAR(出生日期)>35


    正确答案:D
    D。【解析】因为是要求年龄的值,因此是YEAR(DATE)-YEAR(出生日期))>35,在SQL语句中别名的方式应用YEAR(DATE)-YEAR(出生日期))as年龄,因此选D。

  • 第6题:

    查询所有目前年龄在25岁以下(不含25岁)的职工信息(姓名、性别和年龄),正确的命令是( )。

    A)SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期)年龄FROM职工;

    WHERE年龄<25

    B)SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期)年龄FROM职工;

    WHERE YEAR(出生日期)<25

    C)SELECT姓名,性别,YEAR(DATE())-YEAR(出生日期)年龄FROM职工;

    WHERE YEAR(DATE()).YEAR(出生日期)<25

    D)SELECT姓名,性别,年龄=YEAR(DATE())-YEAR(出生日期)FROM职工;

    WHERE YEAR(DATE())一YEAR(出生日期)<25


    正确答案:C
    通过YEAR函数计算年龄。年份函数YEAR(<日期表达式>/<日期时间表达式>),从指定的日期表达式或日期时间表达式中返回年份。函数值为数值型。系统日期函数DATE
    返回当前系统日期。函数值为日期型。
