A.compared
B.shown
C.subjected
D.conveyed

答案：C
解析：
空格所在的主语是the same data,介词to后面的宾语为：economic analysis；在语义上，二者之间的关系理应为“……数据被用于……分析”。联系上下文可知，the same data指代前面提到的实验数据。因此本题所在句的大致意思是：几十年后，上述实验的数据用于/接受了计量经济学分析。符合句意的只有C选项。

第8题：

●已知有关系模式R(S_NO，S_NAME，AGE)，其中S-NO表示学生的学号，类型为Char[8]，前4位表示入学年份。查询所有2005年入学的学生姓名(S_NAME)，SQL语句是 (24) 。

(24) A．SELECT S_NAME FROM R WHERE S_NO=′2005％′

B．SELECT S_NAME FROM R WHERE S_NO LIKE ′2005％′

C．SELECT S_NAME FROM R WHERE S_NO=′2005%′

D．SELECT S_NAME FROM R WHERE S_NO ′2005%′


正确答案：B
【解析】本题考查的是SQL语言的知识，SQL语言作为最常用的数据库语言，是必考的知识点，考生一定要牢固掌握SQL语言的基本语法和语义，并且能够灵活运用。
在SQL语言中，用％来表示任意长度的通配符，用LIKE表示某种形式的条件。所以"LIKE ′2005％′"的含义是找出所有以2005开头，后面任意长度字符的学号。
