     Going to school means learning new skills and facts in different subjects. Teachers teach and students

learn, and many scientists are interested in finding ways to improve both teaching and learning processes.

     Sian Beilock and Susan Leving, two psychologists at the University of Chicago, are trying to learn

about learning. In a new study about the way kids learn math in elementary school, Beilock and Levine

found a surprising relationship between what female teachers think and what female students learn: If a

female teacher is uncomfortable with her own math skills, then her female students are more likely to

believe that boys are better than girls at math."If these girls keep getting math-anxious female teachers in

later grades, it may create a snowball effect on their math achievement," Levine told Science News. The

study suggests that if these girls grow up believing that boys are better at math than girls are, then these

girls may not do as well as they would have if they were more confident.

     Just as students find certain subjects to be difficult, teachers can find certain subjects to be difficult

to learn-and teach. The subject of math can be particularly difficult for everyone.

     The new study involved 65 girls, 52 boys and 17 first-and second-grade teachers in elementary

schools in the Midwest. The students took math achievement tests at the beginning and end of the school

year, and the researchers compared the scores. The researchers also gave the students tests to tell whether

the students believed a math superstar had to be a boy. Then the researchers turned to the teachers: To

find out which teachers were anxious about math, the researchers asked the teachers how they felt at times

when they came across math, such as when reading a sales receipt. A teacher who got nervous looking at

the numbers on a sales receipt, for example, was probably anxious about math.

     Boys, on average, were unaffected by a teacher's anxiety. On average, girls with math-anxious teachers

scored lower on the end-of-the-year math tests than other girls in the study did. Plus, on the test showing

whether someone thought a math superstar had to be a boy, 20 girls showed feeling that boys would be

better at math-and all of these girls had been taught by female teachers with math anxiety.

     According to surveys done before this one, college students who want to become elementary school

teachers have the highest levels of anxiety about math. Plus, nine of every 10 elementary teachers are

women, Levine said.

1. Sian Beilock and Susan Levine carried out the new research in order to _______.

A. know the effects of teaching on learning

B. study students' ways of learning math

A. end up learning math anxiety from their teachers

B. study the ways their female teachers behave

C. have an influence on their math-anxious female teachers

D. gain unexpected achievement in such subjects as math

A. Prepare two math achievement tests for the students.

B. Tell their feelings about math problems.

C. Answer whether a math superstar had to be a boy.

D. Compare the students' scores after the math tests.

4. What is the finding of the new study?

A. No male students were affected by their teachers' anxiety.

B. Almost all the girls got lower scores in the tests than the boys.

C. About 30% of the girls thought boys are better at math than girls.

D. Girls with math-anxious teachers all failed in the math tests.

5. Which of the following is TRUE according to the text?

A. 117 students and teachers took part in the new study.

B. The researchers felt surprised at the findings of their study.

C. Beilock and Levine are interested in teaching math.

D. Men teachers are better at teaching math than women teachers.

问答题

一、鉴证标的
法院委托价格认证中心对一宗七通一平的待开发建设的空地进行地价鉴证。该宗土地的面积为4000m2,建筑容积率为2.5,拟开发建设为写字楼,土地使用权年期为50年。鉴证人员通过市场调查和项目可行性分析,确定该项目建没开发周期为2年,取得土地使用权后即可动工,建成后能够对外出租,可出租面积占建设面积的75%,每平方米建筑面积的年租金预计为480元,年租金损失以一个月租金计。房屋出租中每年的经营费用包括:管理费按年租金的5%计,年维修费按年租金的8%计,租赁税金按年租金的12%计,保险费不计。建筑费预计每平方米建筑面积为1500元,专业费为建筑费的10%,建筑费和专业费第一年投入总额的40%,第二年投入总额的60%。销售税费按不动总价的10%计。假设当地银行的年贷利率为6%,土地还原利率和不动产综合还原利率均为8%,开发商要求的总利润为所开发不动产总价的12%。
二、测算过程
(一)测算不动产总价
1.不动产建筑面积=土地面积×容积率=4000×2.5=10000(m2)
2.不动产年纯收益=480×10000×75%×[1-(5%+8%+12%)]=2700000(元)
3.不动产尚可收益年期为50年
4.不动产总价=2700000/8%×[1-1/(1+8%)50]=33030409(元)
(二)测算建筑费和专业费
建筑费及专业费=1500×10000×(1+10%)=16500000(元)
(三)测算利息
利息=地价×[(1+6%)1-1]+建筑费及专业费×[(1+6%)1-1]
=0.06×地价+990000
(四)测算销售税费
销售税费=不动产总价×10%=33030409×10%=3303041(元)
(五)测算利润
利润=不动产总价×利润率=33030409×12%=3963649(元)
(六)测算地价
地价=不动产总价-建筑费及专业费-利息-销售税费-利润
=33030409-16500000-(0.06×地价+990000)-3303041-3963649
=8273719-0.06×地价
解得:
地价=7805395(元)
