现在，很多学校一直都在提倡无手机课堂，大部分中国高中在课堂上都会禁止学生使用手机等电子产品，甚至大学都有这个争议。今天，我们就一起来看一则相关话题的真题吧~
考题：
Some college and university professors prohibit (do not allow) the use of devices that can connect to the Internet, such as laptop computers (portable computers), tablets, or smartphones, while class is going on. Do you agree or disagree with this policy?
典型的二选一题型，可以采用一边倒的结构或者让步的结构，建议使用让步的结构体现辩证的思维。所以这道题可以选择disagree的立场：主体段1：使用这些产品可以帮助学生理解课堂内容。
主体段2：使用这些产品可以让教授互动更方便。
让步段：尽管电子产品会让学生在课堂上分心，比如玩游戏，听歌等。但是没有自控力的学生就算禁止玩电子产品依然会游神，不专心听讲。所以真正让学生分心的不是电子产品的诱惑而是他们愿不愿意听课。
下面我们拿主体段1做范例：
主体段1的拓展可以是大学的课程内容十分广泛和详细，所以需要学生有丰富的知识面。但是大多数大学生并木有这样广博的知识，所以允许被使用电子产品很重要。例子：如果一个教授提出一个全新的概念，学生能立马使用这些电子产品，帮助他们跟得上课程的内容。
范例参考段落：
To start with, electronic devices could ameliorate difficulties students may have in understanding class content. To elaborate, studies in university are prone to be extensive and detailed, requiring students to have to have access to a broad range of knowledge, which the average university student is unlikely to obtain in a short time. Therefore, the need to apply certain electronic devices such as laptops and cellphones to help them to cope with the issues at hand, is crucial for success. To illustrate, it is common that for a professor to put forward a totally alien concept for students to work through. In this case, not only could learners immediately discover the core premise of the conception, but could also raise any questions after the professor’s lecture, if any uncertainties remained. Thus, it is to the credit of those high-tech gadgets that they are better able to stimulate students’ comprehension of their classes.
