         (16) [A recent study found that 10 percent of British children suffer from maths anxiety. This means they have “overwhelming negative emotions” towards the subject,] ranging “from rage to despair”. Other emotions triggered by maths include feelings of tension and frustration. Physical symptoms include a racing heart or struggling to catch breath. The phenomenon of maths anxiety is characterised as a “general sense of feeling that the subject is hard compared with other subjects”, leading to a subsequent lack or loss of confidence. The researchers said they investigated individuals’ attitudes towards mathematics because of what could be referred to as a ‘mathematics crisis’ in the UK. (17) [There is a widespread misunderstanding that only low-performing children suffer from maths anxiety.] People automatically assume children are anxious about maths because they are poor achievers. In fact, more than three quarters of children with high levels of maths anxiety are normal to high achievers. Probably their maths anxiety will go unnoticed because their performance is good. But in the long term, their performance is negatively affected. So a real danger here is that children who are completely able to do maths at a normal level may keep away from it because they feel anxious. Maths anxiety can severely disrupt students’ performance in the subject in both primary and secondary school. But importantly—and surprisingly—(18) [this new study suggests that the majority of students experiencing maths anxiety have normal to high maths ability.]

17. What is the widespread misunderstanding about maths anxiety?（关于数学焦虑普遍存在的误解是什么？）

解析：B。录音中表示，人们普遍存在一种误解，认为只有成绩差的孩子才会有数学焦虑症。B项中的low-performing children和only为原词复现，故B项正确。

错项排除：A项在录音中未提及，故排除。录音中提到的low-performing指的是孩子成绩不佳，并非智力低下，故C项错误。D项利用录音中的poor-achievers设置干扰，但录音中说的是成绩不好的学生，而不是贫困学生，故排除D项。
