问题 单项选择题

执行下列一组命令之后,选择“职工”表所在工作区的错误命令是 CLOSE ALL USE 库 IN 0 USE 职工 IN 0

A.SELECT 职工

B.SELECT 0

C.SELECT 2

D.SELECT B

答案

参考答案:B

解析: 在Visual FoxPro中, SELECT 0是选择一个编号最小且没有使用的空闲工作区。执行题干中两条打开表的命令后,“职工”表所在工作区为2号工作区。若想在工作区之间切换,可以用SELECT<工作区号>来指定工作区,同时又可以SELECT 工作区别名来指定工作区,职工表的系统默认的工作区别名是表名和字母B,因此选项ACD都可以实现选择“职工”表所在工作区,故答案为B选项,这个命令实现的是选择“仓库”表所在的工作区。

The arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had some musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas.

Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang (团伙). Parents can enjoy listening to their children's music instead of seeing them glued to a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music.

Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of, and it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence.

Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school.
