共用题干Teaching Math,Teaching AnxietyIn a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan 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 said Levine. In other words,girls may end up learning math anxiety from their teachers. 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一and teach. The subject of math can be particularly difficult for everyone. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The 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 that 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一and all of these girls had been taught by female teachers who had math anxiety.“This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.What is the result of the research at the University of Chicago,according to the first paragraph?A:Girls comfortable with their own math skills are better than boys at math.B: Girls uncomfortable with their own math skills are not as good as boys at math.C: Female teachers'math skills have influence over girl students'math skills.D: Female teachers'confidence in their math skills is related to girls'math skills.

根据下面资料，回答That year, in the local school, there was a new math teacher, as well as some new pupils. One of the new kids was the stupidest child that anyone had ever seen. It made no difference how quickly or how slowly they tried explaining numbers to him; he would always end up saying something enormously stupid. Like two plus two was five, seven times three was twenty-seven, or a triangle had thirty comers, etc. Before this boy arrived, math lessons had been the most boring of all. Now they were great fun. Encouraged by the new teacher, the children would listen to the pieces of nonsense spouted by the new kid, and they would have to correct his mistakes. Whenever the new teacher asked questions, the stupid kid would stand up but made the wrong answers, the other students all wanted to be the first to find his mistakes, and then think up the most original ways to explain them. To do this they used all kinds of stuff: sweets, playing cards, oranges, paper planes, etc. It didn′t seem like any of this bothered the new kid. However, little Lewis was sure that it was bound to make him feel sad inside. Lewis was sure he would see him crying. So, one day, he decided to follow the new kid home after school. On leaving school, the new kid walked a few minutes to a local park, and there he waited for a while, until someone came along to meet him. It was the new teacher! The teacher gave the new kid a hug, and off they went, hand in hand. Following from a distance, Lewis could hear they were talking about math. What does the passage imply?A.The stupid student was not good at math.B.The stupid student was by no means slow in math.C.The stupid student had no gift for math and was slow in math.D.The stupid student disliked both the new math teacher and his lessons.
