If there is no difference in general intelligence (智力) between boys and girls, what can explain girls poor performance in science and mathematics?
It seems to be that their treatment at school is a direct muse. Mathematics and science are seen as subjects mainly for boys, and therefore, as girls become teenagers, they are less likely to take them. Interestingly, both boys and girls often regard the subjects for boys as more difficult. Yet it has been suggested that girls do not take mathematics courses, not because they are difficult, but for social reasons. Girls do not want to be in open competition with boys because they are afraid to appear less feminine (女性的) and attractive.
However, if we examine the performance of boys and girls who have taken mathematics courses, there are still more high-achieving boys than there are girls. This difference appears to be world-wide. Biological explanations have been offered for this, but there are other explanations too.
Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences. From their first days in kindergarten, boys are encouraged to work on their own and to complete tasks. Facts show that outstanding mathematicians and scientists have not had teachers who supplied answers.
Besides, there can be little doubt that teachers of mathematics and science expect their boy students to do better at these subjects than their gift students. They even appear to encourage the difference between boys and girls. They spend more time with the boy students, giving them more time to answer questions and working harder to get correct answers from them. They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion. They also praise boys more frequently. All of this seems to encourage boys to work harder in science and mathematics and to give them confidence that they are able to succeed.
Such a way of teaching is not likely to encourage girls to take many mathematics and science courses, nor is it likely to support girls who do. When it comes to these subjects, it seems certain that school widens difference between boys and girls.

查看习题详情和答案>>Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1897, Irene Curie was the first of the Curies' two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognised in the form of a Military Medal by the French government.
In 1918, Irene became her mother's assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.
Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, "also like her mother, she developed leukemia because of her work with radioactivity (辐射能). Irene Joliot-Curie died from leukemia on March 17, 1956.
59. Why was Irene Curie awarded a Military Medal?
A. Because she received a degree in mathematics.
B. Because she contributed to saving the wounded.
C. Because she won the Nobel Prize with Frederic.
D. Because she worked as a helper to her mother.
60. Where did Irene Curie meet her husband Frederic Joliot?
A. At the Curie Institute. B. At the University of Paris.
C. At a military hospital. D. At the College of Sévignfé.
61. When was the second child of Irene Curie and Frederic Joliot born?
