问题     Teacher burnout and student stress may be linked, according to a University of British Columbia study.
    The study is the first of its kind to examine the connection between teacher burnout and students’ Cortisol (皮质醇) levels, which are a biological indicator of stress.
    Researchers collected saliva (唾液) samples from over 400 elementary school children and tested their Cortisol levels. They found that in classrooms in which teachers experienced more burnout, or feelings of emotional exhaustion, students’ Cortisol levels were elevated. Higher Cortisol levels in elementary school children have been linked to learning difficulties as well as mental health problems.
    "This suggests that stress contagion (传染) might be taking place in the classroom among students and their teachers," said Eva Oberle, the study’s lead author and newly appointed assistant professor with the Human Early Learning Partnership (HELP) at UBC’s school of population and public health. "It is unknown what came first—elevated Cortisol or teacher burnout. We consider the connection between student and teacher stress a cyclical problem in the classroom. "
    Oberle said a stressful classroom climate could be a result of inadequate support for teachers, which may impact teachers’ ability to effectively manage their students. A poorly managed classroom can contribute to students’ needs not being met and increasing stress. This could be reflected in elevated Cortisol levels in students.
    Alternatively, stress could originate from students, who may be more challenging to teach because of increases in anxiety, behavioral problems, or special needs. In this scenario, teachers could feel overwhelmed and report higher levels of burnout.
    "Our study is a reminder of the systemic issues facing teachers and educators as classroom sizes increase and supports for teachers are cut," said Oberle.
    "It is clear from a number of recent research studies that teaching is one of the most stressful professions, and that teachers need adequate resources and support in their jobs in order to battle burnout and alleviate stress in the classroom," said UBC education professor Kimberly Schonert-Reichl, the study’s co-author and director of HELP. "If we do not support teachers, we risk the collateral damage of students."
It can be concluded from the research made by University of British Columbia that_________.
选项 A、Cortisol levels were verified to be a reliable indicator of pressure
B、children’ Cortisol levels were measured by their saliva
C、students’ Cortisol levels were influenced by teachers’ burnout
D、the rising of Cortisol levels was related to psychological problems
答案C
解析 推理判断题。第三段第二句提到，研究人员发现，在教师表现出更多倦怠或情绪疲劳感的班级，学生们的皮质醇含量会有所上升。由此推断，学生们的皮质醇含量受教师职业倦怠的影响，故答案为C)。A)“皮质醇含量被证实是一个可靠的压力指标”，原文并未提及皮质醇含量作为判断压力的可靠性，故排除；B)“儿童的皮质醇含量通过测量唾液得出”，第三段第一句提到，研究人员收集了400多个小学生的唾液样本，并测试了他们的皮质醇含量，该选项在原文直接提及，无需推断，故排除；D)“皮质醇含量的升高与心理问题有关”，第三段最后一句表明，在此次研究之前，皮质醇的较高含量就已经与小学生的学习困难及心理健康问题联系在一起了，由此可知，皮质醇含量的升高与心理问题有关并非此次研究得出的结论，故排除。
