问题     Online classes began to be popularized just a few decades ago. They are advertised as a way for adults to finish their education and students to learn the material at their own pace—it is far more compatible for people with busy schedules.
    But after being enrolled in an online course last fall semester, I came to realize online classes were merely a means to fulfil course requirements.
    First of all, students lack the desire to learn, and they simply complete their assignments to receive credit for a passing grade rather than genuinely engage with the course material.
    As online courses tend to have more than 100 students, most of the assignments are short and simple. They are not designed for students to interact with the material in depth but designed to be graded easily to accommodate such a large number of students.
    Perhaps the biggest disadvantage of taking an online class is the absence of face-to-face interaction between the teacher and their students. Live sessions are infrequent and are often scheduled during the middle of the day when students have to attend other classes or work. The office hours of the professor may also be during inconvenient times for many students as well. Most interaction with the professor has to be through email which is often impersonal. It is nearly impossible for students to build a relationship with their professor.
    There is also little interaction amongst students. It can be harder for students to create study groups and form relationships with their peers.
    Online classes also require either a computer or laptop and a reliable internet connection. Not all students have access to these types of resources, whether it is for financial or other reasons, and some students can be put at a disadvantage.
    Offering online classes certainly helps students who would otherwise not be able to attend classroom sessions. However, they fail to provide a genuine education with an emphasis on convenience rather than critical thinking. We need restructured online classes in which students can have a learning experience that will actually provide quality education.
What does the author say is one disadvantage of online classes?
选项 A、They are frequently scheduled at irregular times.
B、They make professors’ offices much less accessible.
C、They tend to increase professors’ burden of responding to students’ emails.
D、They provide little chance for students to build relationships with each other.
答案D
解析 细节辨认题。定位句提到，也许参与在线课程的最大缺点是教师和学生之间缺乏面对面的互动。第六段进一步指出，学生之间的互动也很少，学生很难创建学习小组并与同龄人建立关系。故正确答案为D)。第五段第二、三句提到在线课程的时间问题：直播课程通常安排在正午，因为学生不得不参加其他课程或工作。很多学生可能也不方便在教授的办公时间上课。文章没有提到在线课程被安排在不定期的时间，也不能由此推出在线课程使教授的办公室更难进入，故排除A)和B)。第五段第四句提到，与教授的大多数互动都必须通过电子邮件进行，这往往缺少人情味，旨在表明学生和教师间的交流变少了，而不是说教授回复学生电子邮件的负担增加了，故排除C)。
