【简答题】
Jane: Hi, welcome to Hal’s Computer World. {A. Does he have any brand preference?; B. How much is it?; C. I’ll come back to buy it this weekend.; D. Can I help you?; E. How about this one?} Smith: I would like to buy a computer for my son. I was told it is cheaper to buy computers here. Do you have any recommendations? Jane: Yes. We have plenty of choices for you. So, home computer or a laptop, which one does he like? {A. Does he have any brand preference?; B. How much is it?; C. I’ll come back to buy it this weekend.; D. Can I help you?; E. How about this one?} Smith: He prefers ASUS(华硕), laptop, which is much more convenient. Jane: I see. {A. Does he have any brand preference?; B. How much is it?; C. I’ll come back to buy it this weekend.; D. Can I help you?; E. How about this one?} ASUS F83E335Cr-SL. It is really suitable for students. Smith: Let me see. Well, it’s good but I don’t think 320 GB is enough. Jane: If you wish to upgrade the hard drive, we can definitely do so. It costs 150 to upgrade it from 320GB to 500GB. Smith: Great. My son likes keeping a lot of movies and pictures on the hard drive. Jane: No problem. I’ll give you a more detailed brochure later. Smith: Thank you. {A. Does he have any brand preference?; B. How much is it?; C. I’ll come back to buy it this weekend.; D. Can I help you?; E. How about this one?} May I have a discount? Jane: In total it costs 3900 yuan. If you pay for it on Saturday or Sunday this week, you can actually get 5 percent off the usual sale price. Smith: Wow. That’s really good. {A. Does he have any brand preference?; B. How much is it?; C. I’ll come back to buy it this weekend.; D. Can I help you?; E. How about this one?}

B.
科目只是理论上的规定 ， 账户是按照科目统一规范进行核算的一种实用技术
C.
科目仅仅是账户的名称 ， 账户有其基本结构和具体结构
D.
科目是账户的单一名称 ， 账户是用来归集发生在同一科目下的多条记录
【简答题】已知函数f（x）=x 3 +ax 2 -9x+b的图象过点P（0，2），且f′（1）=0． （1）求函数y=f（x）的解析式； （2）求函数y=f（x）的单调区间．
【简答题】已知函数f（x）=x 3 +ax 2 +bx+c，点P（1，f（1））在函数y=f（x）的图象上，过P点的切线方程为y=3x+1． （1）若y=f（x）在x=﹣2时有极值，求f（x）的解析式； （2）在（1）的条件下是否存在实数m，使得不等式f（x）≥m在区间[﹣2，1]上恒成立，若存在，试求出m的最大值，若不存在，试说明理由．
【简答题】已知函数f（x）=x 3 +mx 2 +nx-2的图象过点（-1，-6），且函数g（x）=f′（x）+6x的图象关于y轴对称。（1）求m、n的值及函数y=f（x）的单调区间； （2）若a＞0，求函数y=f（x）在区间（a-1，a+1）内的极值。

【多选题】账户与会计科目的区别表现在( )。
A.
两者分类的标准不一致,因此核算的内容也不同
B.
账户有结构,会计科目则无
C.
账户不是依据会计科目开设的,两者名称不一致
D.
会计要素的增减变化要在账户中进行登记,而会计科目则不能
【简答题】已知函数f（x）=x 3 +ax 2 +bx+c在x=0和x=2处取得极值，且函数y=f（x）的图象经过点（1，0）． （1）求函数f（x）的解析式； （2）设A、B为函数y=f（x）图象上任意相异的两个点，试判定直线AB和直线4x+y-3=0的位置关系并说明理由； （3）设函数g（x）=x 2 +mx+6，若对任意t∈[-2，2]且x∈[-2，2]，f（t）≤g（x）恒成立，求实数m的取值范围．
