4. The sixth paragraph tells us that the research findings
A prove a strong link between female teachers math anxiety and their female students math achievements.
B show that male students are less likely to be affected by their math anxiety than female students.
C provide strong evidence that math superstars are more likely to be males than females.
D discover a strong link between teachers math anxiety and their students math achievements.
5. David Geary thinks that
A the study is interesting but it is based on unreliable research process.
B the research results need to be retested based on a larger sample.
C the research results need to be reinterpreted to be meaningful.
D the study is well based and produces significant results.
答案与题解：
1.D 该段告诉我们女教师的想法(what female teachers think)和女学生的学习(what female
students learn)之间有很大的关联度，也就是说，女教师如果对自己的数学技能没有自信，她的女学生很可能相信男孩子会在数学方面超过女孩子。
2.B 第三段的大意是，数学对任何人来说都可能有难度(The subject of math can be particularly difficult for everyone)，如同学生，教师也会觉得数学难学和难教，这就是研究者所言的焦虑。所以，可以推断，作者是要告诉我们，教师会因为数学这门学科的难度而对教授该课程不自信。其他选项都不是该段所要表达的内容。
3.C 第五段第三句"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"指出了答案。memorizing the numbers;意为"记住数字"；saving the numbers意为"保存数字"；filling in the numbers意为"陆续编入数字"，而且文中没有提到a sales report;它们均不是答案。
4.A 短文的第六段是对前一段所述调查数据结果的讨论，即，男学生较少受对数学有焦虑感的教师影响，而那些数学成绩较低的女生都有对数学有焦虑感的教师(girls with math-anxious
teachers scored lower on the end-of-the-year math tests)，而且，所有认为男生数学肯定比女生强的女生，其数学教师都是有数学焦虑感的女教师(all of these girls had been taught by female teachers who had math anxiety. )。D所以不是正确的选择，因为只提到teachers 和students，而不是female teachers 和female students.
5.B 根据David Geary的说法，实验结果还是初步的(preliminary)，需要更大的样本对其进行重复验证(in need of replication with a larger sample)。他没有认为该实验的过程不可靠，所以A不是正确选项；他认为实验样本不够大，所以D也不是正确选项
