正确答案：(1)JMP LAST (2)SUB GR0WDTGR1 (3)ST GR2BTASCGR1 (4)ADD GR0C48 (5)ST GR0BTASCGR1
(1)JMP LAST (2)SUB GR0，WDT，GR1 (3)ST GR2，BTASC，GR1 (4)ADD GR0，C48 (5)ST GR0，BTASC，GR1 解析：本程序是将16位无符号二进制数转换为5位十进制数。
程序的前3句是对寄存器赋初值，DATA数据(即要转换的数)被读取到GR0，GR1置为0，GR3置为48。第四句是一个逻辑比较语句(从这个语句可以看出，GR1用作 WDT的偏移地址)，比较GR0和WDT中的数据的大小。
WDT开始的5个连续空间的数据分别为“10000，1000，100，10，5”。因为当前的 GR1为0，所以WDT对应的为“10000”，当GR0大于等于(WDT)时转LOOP2，小于 (WDT)则继续往下执行。其实在这种情况下，最好的分析方法就是把DATA中的数据自己手动转成十进制，然后把数据代到程序里，跟踪程序的执行，这样能最快的了解程序的执行流程和处理方法，同时也做了验证工作。
因为#FA59H转成十进制是64089。所以现在程序转到LOOP2执行。GR2置48，单从这里无法了解GR2是什么用途。比较GR0与(WDT+GR1)的大小，GR0比10000大，所以执行(2)，再执行“LEAGR2，1，GR2”即把GR2自加1(结合题目提到的“转换结果用ASCH码表示”，可以了解到GR2的用途，因为48正好是ASCII码的“0”，自加就变成“1”了，所以GR2是统计GR0中(WDT+GR1)的个数并把它转化为ASCII码形式)。
然后再转向LOOP3执行，这样又回到了前面比较。在已知的语句中并没有对GR0， GR1进行变动，所以(2)中一定是对这2个寄存器值的改变，不然这段循环就成了死循环了。结合“LEAGR2，1，GR2”的功能，可知(2)应是对GR0自减一个(WDT+GR1)，即 SUB GR0，WDT，GR1。
程序分析到这里，可以了解到NEXT标号后的语句是为下一步的统计做准备，即首先保存上一步已统计的“10000”的个数，再为统计“1000”的个数，为寄存器置初始值，程序已有“LEA GR1，1，GR1”，它能使WDT+GR”指向1000，所以(3)空要完成的功能是把“10000”的个数放到指定的位置，又因为题目中提到“转换结果用ASCII码表示，并从高位至低位依次存放在首地址为BTASC的连续5个内存单元中”，所以(3)空应填ST GR2，BTASC，GR1。
接下来执行“LEAGR2，-4，GR1”GR1中存的是偏移量。当统计万位时，GR1为0；当统计千位时，GRl为1，要(GR1)-4为0，即GR1为4，应是统计个位数字。所以(4)和 (5)空是统计个位数字，其实这点在程序注释部分也有提及。
那么如何利用已知数据，且用2步完成功能呢?这里注意到一个重要寄存器GR0。 GR0中现存的数就是个位数了，因为通过上面的几次循环，GR0中高位都被减掉了，所以现在只需把GR0加上一个48，然后再存入(BTASC+4)内存空间即可。其实把GR0加 48的方法很多，但是一定要注意一个问题，不能用LEA GR0，48，GR0，因为GR0寄存器是不能用变址寻址的。又因为程序中用到了C48，但一直没有语句用到过，所以用 ADD GR0，C48是最合适的。至此(5)空毫无疑问填ST GR0，BTASC，GR1。
最后就剩(1)了。当万位为0时，就可以执行“JPZ LOOP2”后面的一段程序了，“ST GR3，BTASC，GR1”是把“0”存入BTASC+GR1位置。接下来的3条语句都已经很明显了，与程序的倒数第3，4，5条语句完成同样的功能，即判断是否已经处理到个位了，如果是，则直接转到LAST进行个位处理，所以(1)空应填JMP LAST。

第5题：

Write a composition of at least 150 words based on the folio-wing picture.You should describe the picture, give your opinion on the topic, and use specific reasons and Ior examples to support yourself.Write your answers on the ANSWER SHEET.


正确答案：The Moral Standard of Young People Should Be Improved In the provoking picturea young man is sitting on the chair in an auto bus that is allocated specially for the oldthe weakthe pregnantthe disabledchildren and the like. Regrettably he might have neglected the pregnant lady standing just beside him.The painful scene leads us to think seriously about the moral decline in the country. Some of this can be attributed to moral degeneration a problem existing particularly in the younger generation. Their sense of moral standards seems to be withering although their material comforts have been considerably enhanced. What makes matters even worse is the fact that such misdeeds as spitting picking flowers in public gardens or making noises in public places are becoming so pervasive that they are likely to be taken for granted by the public. With today"s worsening morality social bonds have been weakened replaced by a greater emphasis on the self. That is why new ideas must come forward to improve the country"s moral climatethough the challenge cannot be underestimated. Moral decline will not be reversed until we find new ways to improve our moral standards. The government can launch more etiquette lessons in communities to help young people correct poor public manners such as queue jumping and speaking loudly.At the same time young people should also be aware of the importance of good manners and try to defend social morality. Only in this way can the moral climate of our nation be improved and we sincerely wish that the young man in the picture could realize that he has sat on a "wrong" seat.

第7题：

设在SQL Server 2008某数据库中有表SC（Sn0，Cn0，Grade），其中Grade列的类型为int。若在查询成绩时，希望将成绩按“优”、“良”、“中”、“及格”和“不及格”形式显示，则下列Case函数中正确的是（ ）。

A.Case GradeWhen Grade between 90 and 100 THEN Grade=ˊ优ˊWhen Grade between 80 and 89 THEN Grade=ˊ良ˊWhen Grade between 70 and 79 THEN Grade=ˊ由ˊWhen Grade between 60 and 69 THEN Grade=ˊ及格ˊElse Grade=ˊ不及格ˊEnd

B.Case GradeWhen Grade between 90 and 100 THEN ˊ优ˊWhen Grade between 80 and 89 THEN ˊ良ˊWhen Grade between 70 and 79 THENˊ中ˊWhen Grade between 60 and 69 THENˊ及格ˊElseˊ不及格ˊEnd

C.CaseWhen Grade between 90 and 100 THEN Grade=ˊ优ˊWhen Grade between 80 and 89 THEN Grade=ˊ良ˊWhen Grade between 70 and 79 THEN Grade=ˊ由ˊWhen Grade between 60 and 69 THEN Grade=ˊ及格ˊElse Grade=ˊ不及格ˊEnd

正确答案：D
此题考察了SQL中CASEWHEN语句的用法。如果是简单的赋值查询，比如数据库表示性别：1表示男，2表示女。则用CASEsexWhenˊ1ˊTHENˊ勇ˊWhenˊ2ˊTHENˊ女ˊELSEˊ其它ˊEND即可以表示。但如果条件较为复杂或包含判断式等，则用D所表示的方式。

第8题：

若要使所有学科80分以上的成绩都增加5%, 80至60分的成绩都增加10%，应如何更新数据库（ ）。 A．UPDATE SC SET GRADE=GRADE*1．05 WHERE SC．GRADE>=80 UPDATE SC SET GRADE=GRADE* 1．10 WHERE SC．GRADE>=60 AND SC．GRADE <=80 B．UPDATE SC SET GRADE=GRADE* 1．10 WHERE SC．GRADE>=60 AND SC．GRADE<=80 UPDATE SC SET GRADE=GRADE* 1．05 WHERE SC．GRADE>=80 C．UPDATE SC SET GRADE=GRADE* 1．05 WIRE SC．GRADE>=80 AND SET GRADE =GRADE* 1．10 WHARE SC．GRADE>=60 D．UPDATE SC SET GRADE=GRADE* 1．10 WHERE SC．GRADE>=60 AND SC．GRADE <=80 AND SET GRADE=GRADE* 1．05 WHERE SC．GRADE>=80


正确答案：A
Update 语句用于修改表中的数据,语法：UPDATE 表名称 SET 列名称 = 新值 WHERE 列名称 = 某值，根据语法，表名称应该为SC，GRADE=GRADE*1．05，条件为SC．GRADE>=80，后面的60到80分的同理。
