Teaching Math, Teaching Anxiety

In 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
A. the research results need to be reinterpreted to be meaningful
B. the study is well based and produces significant results
C. the study is interesting but it is based on unreliable research process
D. the research results need to be retested based on a larger sample

[单项选择]Promising Results from Cancer Study A new experimental vaccine (疫苗) has shown promising results in the fight against lung cancer. In a small Texas-based study, a vaccine developed by scientists at Baylor University Medical Centre in Dallas, USA, cured lung cancer in some patients and slowed the progress of the disease in others. Researchers have reported encouraging findings from this small study. Forty-three patients suffering from lung cancer were involved in these trials. Ten of these patients were in the early stages and thirty-three in the advanced stages of the disease. They were injected with the vaccine every two weeks for three months, and were carefully monitored for three years. In three of the patients in the advanced stages of cancer, the disease disappeared and in the others, it did not spread for five to twenty-four months. However, no great difference was seen in the patients in the early stages of the illness. This new vaccine uses the patients’ own immune system. I
