    试题内容
        For reasons that are deeply rooted in culture and tradition, men significantly outnumber women in mathematics-based careers. As students progress through the mathematics courses, girls and boys show little difference in ability, effort, or interest in mathematics until adolescent years when course and career choices begin influencing school effort. Then, as social pressure increases and career goals are formed, girls' decisions to reduce effort in the study of mathematics progressively cut them off from many professional careers in the future. 
        Many girls drop mathematics in high school or in the transition to college. Others drop out later. Women perform virtually as well as men in college mathematics courses, but beyond the bachelor's degree women drop out of mathematics at twice the rate of men. Women now enter college nearly as well prepared in mathematics as men, and 46 percent of mathematics baccalaureates (学士学位)go to women. Despite this record, only 35 percent of the master's degrees and 17 percent of the Ph. D degrees in the mathematical sciences are earned by women. 
        Overall, women receive approximately one third of university degrees in science and engineering. The highest percentages of women are found in those sciences with the least mathematical prerequisite: psychology, biology, and sociology. The lowest percentages of women enter fields requiring the most mathematics, namely, physics, engineering, economics, geo-science, and chemistry. Evidence from many sources suggest that it is differences in course patterns rather than lack of ability that matter most in limiting women's access to careers in mathematically intensive sciences. 
    Widely reported studies concerning the high percentage of boys among mathematical prodigies ( 天才. —those who at age 12 perform at the level of average college students—often convey the impression that gender differences in mathematics are biologically determined. But evidence from the vast majority of students shows almost no difference in performance among male and female students who have taken equal advantage of similar opportunities to study mathematics. Inferences ( 推论)from very exceptional students—child prodigies—mean little about the performance of the general population. 
    1.[单选题]The high percentage of boys among mathematical prodigies __.
    • A.means that boys are cleverer in mathematics than girls
    • B.doesn't mean that boys are cleverer in mathematics than girls
    • C.means that boys do much better in math exams than girls
    • D.may be explained by the fact that boys work harder than girls
    • 解题思路:根据题干信息mathematical prodigies可将答案定位到第四段第一、二句。文章最后一段提到: “数学天才中男生的比例要远高于女生……但是,大多数学生的经历表明,在数学学习上享有均等机会的学生,不论男女,学习成绩几乎不会有太大的差别。从个别学生(比如少年天才)身上推断出来的结论并不适用于一般人?!币簿褪撬?,数学天才中男生要多于女生,但这并不意味着男生就天生有学习数学的优势。故选B。
    2.[单选题]According to this passage,which of the following is NOT TRUE?
    • A.Many girls decide to reduce effort in the study of mathematics as social pressure increases.
    • B.More women drop out of mathematics than men beyond the bachelor ’s degree.
    • C.Women tend to prefer the majors such as psychology,biology,and sociology.
    • D.Women ’S less interest in mathematics limits their access to some careers.
    • 解题思路:根据题干信息which of the following is true可知解答本题需通观全文。本题需结合文章内容一一排除。第一段最后一句提到: “随着社会压力的不断增加以及职业目标的形成。女生决定在数学学习上不再那么用功”可见选项A表述正确。第二段第三句提到:“当学习阶段超过了本科之后,放弃学习数学的女生的数量是男生的两倍?!笨杉鸅也正确。第三段第二句提到:“女生人数比例最高的专业往往是那些对数学要求最低的专业,比如心理学、生物学和社会学?!笨杉?,女生倾向于选择心理学、生物学、社会学等专业,故C也正确。文章并没有提到女性对数学比较不感兴趣.也就无从推断这是她们不能涉足许多职业的原因,故D为正确答案。
    3.[单选题]According to the author, the learning abilities of males and females in mathematics are similar until they____.
    • A.enter high school
    • B.enter college
    • C.acquire their bachelor's degree
    • D.acquire their master's degree
    • 解题思路:根据题干信息the learning ability of males and females in mathematics可将答案定位到第一段第二句。 第一段提到: “一开始男生和女生在数学学习的能力、努力程度或者兴趣方面并没有表现出太大的差异,直到青少年时期,课程和职业选择开始影响到学习上的努力,他们之间的差距就拉开了?!蔽纳甑摹扒啻浩谥啊负醯韧谏细咧兄?。而且第二段也提到:“有很多女生在高中或者在高中到大学的过渡期间放弃了学习数学?!闭飧用魅分甘玖吮咎獾恼反鸢赣Ω檬茿选项。
    4.[单选题]___ is the factor that limits women's access to careers in mathematically intensive sciences.
    • A.Lack of ability
    • B.Culture
    • C.Effort
    • D.Course pattern
    • 解题思路:根据题干信息limits women’s access to careers,mathematically intensive sciences可将答案定位到第三段最后一句。原文提到: “很多方面的资料都表明,限制女性进入对数学水平要求较高的职业的最重要的因素是课程模式不同,而不是她们缺乏能力?!惫蚀鸢肝狣,其他几项都是干扰内容。
    5.[单选题]Of the following degrees, the lowest percentage of degree earned by women is.
    • A.master's degree in economics
    • B.master's degree in biology
    • C.doctor's degree in economics
    • D.doctor's degree in biology
    • 解题思路:根据题干信息the lowest percentage of degree earned by women可将答案定位到第三段第三句。原文提到: “在那些对数学要求最高的专业(比如,物理、工程学、经济学、地理科学以及化学等专业),女生所占的比例最少?!痹儆傻诙文┪泊Φ?6%、35%、l7%可知,与数学有关的专业的学位越高?;竦酶醚坏呐簿驮缴?。因此答案应为C。
