37. New policies adopted by many US schools require students to do online learning at home in case of a school closure.
（本题出自2024年6月四级真题卷三）
答案&解析：
37.C。
由题干关键信息New policies、many US schools、online learning和school closure定位到C段。该段最后两句承接上文提到，本学年，许多学校董事会都出台了政策，要求学生在学校因下雪或极端天气停课时在家学习。这被称为“线上学习日”,听起来当然没有雪休日有趣。由此可知，题干是对原文内容的概括总结。其中New policies adopted by many US schools对应原文中的many school boards haveintroduced policies,而require students to do online learning at home对应原文中的require students to work fromhome和“e-learning days”,而in case of a school closure对应原文中的if the school is shut by snow or extremeweather。
