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 about students enrolled in online classes?
【正确答案】
B
【答案解析】细节辨认题。第二段起到承上启下的作用。第三段指出,学生缺乏学习的欲望,他们只是简单地完成作业以获得及格的分数,而没有真正参与到课程学习中。故正确答案为B)。A)是根据第三段最后提到的the course material设置的干扰,但是该句说的是“学生不能真正参与到课程学习中”,并没有提及学生是否可以轻松获得课程材料,故排除A)。C)是根据第一段第二句提到的students to learn...at their own pace设置的干扰项,但这是人们宣传的在线课程的优点,而不是作者的观点,故排除C)。第二段提到,作者意识到在线课程只是满足课程要求的一种手段,并没有说学生很少达到课程要求,故排除D)。

Why did a recent debate published in The New York Times arouse concerns among experts?
【正确答案】
B
【答案解析】推理判断题。第二段首句介绍这场辩论,第三句提到一些专家的担心:这种公开的猜测可能会导致人们认为,细节上的分歧意味着对现代医学的安全性和效率缺乏足够的科学共识。由此可以推断,这会引起公众对现代医学不信任,故答案为B)。第二段前两句说明了这场辩论讨论的问题,并没有提及这场辩论会阻碍医学进展,故排除A)。文中并未提及研究资金的问题,故排除C)。D)是根据第二段末句中a lack of adequate scientific consensus设置的干扰项,此处是表达细节上的分歧意味着对现代医学的安全性和效率缺乏足够的科学共识,并没有提到辩论会阻碍医学科学家达成共识,故排除。

Why does the author say some experts’ anxiety seems misplaced?
【正确答案】
C
【答案解析】细节辨认题。第三段首句指出,这种焦虑似乎放错了地方。末句指出,如今,无论有关科学的辩论发生在哪里,公众都可以接触到,故答案为C)。第三段第二句提到,参加会议并讨论科学问题的日子一去不复返了,这并不是指那样的日子已经过时了,而且这也不是作者认为专家的焦虑放错地方的原因,故排除A)。第三段第二句提到,那些会议不够多样化,并没有提及科学家和公众可以讨论各种各样的话题,故排除B)。文中没有提到科学家应该如何发表观点的问题,而且whatever way they like过于绝对,故排除D)。

What does the author say about science in the last paragraph?
【正确答案】
C
【答案解析】推理判断题。最后一段第二句提到,如果公众要理解科学是一个正大光明的自我纠正的过程,那么,需要摒弃那种认为科学是教科书中一系列固定不变的事实的观点。由此可以推断,科学是一个自我完善的过程,故答案为C)。A)和D)是根据最后一段第二句中a fixed set of facts in a textbook设置的干扰项,此处是表达需要摒弃那种认为科学是教科书中一系列固定不变的事实的观点,不是表达科学通过教材传播或者科学是事实和既定规则的集合,故排除A)和D)。最后一段第三句指出,科学的有效性受到攻击,B)与文章意思相反,故排除。
