英语试题 03-10
In 1992,Teen Talk Barbie was put on the market with the controversial voice fragment(碎片），＂Math class is hard."While the toy's sale met with strong public reaction,this hidden assumption continues,spreading the belief that women do not boom in science,technology,engineering and mathematic(STEM)fields due to biological inadequacies in math talent.
However,in 2019 Jessica Cantlon at Carnegie Mellon University led a research team that thoroughly examined the brain development of young boys and girls and found no sex difference in brain function or math ability.
Cantlon and her team studied the biological sex differences in math ability of young children.Her team used functional MRI(核磁共振）to measure the brain activity in 104 young children（3-to-10-year-old;55 girls)while watching an educational video covering early math topics,like counting and addition.The researchers compared scans from the boys and girls to evaluate brain similarity.In addition,the team examined brain maturity by comparing the children's scans to those taken from a group of adults(63 adults;25 women)who watched the same math videos.
After many statistical comparisons,Cantlon and her team found no difference in the brain development of girls and boys.In addition,the researchers found no difference in how boys and girls processed math skills while watching the educational videos.Finally,boys' and girls' brain maturity were statistically alike when compared to either men or women in the adult group.
Cantlon said she thinks society and culture are likely directing girls and young women away from math and STEM fields."Typical socialization can make worse small differences between boys and girls that can snowball into how we treat them in science and math,"Cantlon said."We need to be aware of these origins to ensure we aren't the ones causing the sex unfairness."
However,this project is focused on early childhood development using a limited set of math tasks.Cantlon wants to continue this work using a broader scope(范围）of math skills,such as spatial processing and memory,and follow the children over many years.
12. What can we infer after Teen Talk Barbie was on sale?
A. Girls are born with poor math abilities.
B. Math is difficult for both boys and girls.
C. Boys perform no better than girls in math.
D. Math is harder than science and technology.
13. What is the third paragraph mainly about?
A. The result of Cantlon's study.
B. The purpose of Cantlon's job.
C. The method of Cantion's research.
D. The difficulty of Cantlon's work.
14. How will Cantlon further her research?
A. By using a larger variety of subjects.
B. By employing a wider range of math skills.
C. By raising the difficulty of the math tasks.
D. By expanding the number of the children.
15. In which part of a magazine will the text most probably appear?
A. Business. B. Sports&Health.
C. Entertainment. D. Popular science.
