2022-2023学年高一下期英语月考试题2023.6 第一部分 阅读理解（共两节，满分50分） 第一节 （共15小题；每小题2．5分，满分37．5分） 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 A    As the COVID-19 continues to spread, officials in China are urging citizens to wear masks in public to stop the spread of the coronavirus (冠状病毒)—and cities in China as well as other parts of Asia are reportedly running out of face masks．     But can a mask really keep you from catching the vims?
