朗阁讲师林森点评

综合写作：

阅读：认为有利

1. 公路使用率下降，降低了维修费，缓解州政府的财政压力；

2. 缓解交通拥堵；
3. 燃料使用率高，减少污染，保护环境。

听力：否定

1. 建立railway line费用很高，还贷款占税收一年75%，政府的财政负担大；


2. 这个地区公共交通不发达，人们还是会选择drive to station；

3. 这个地区的regular route很多会保留，燃料利用率并没有提高。

独立写作：

本题是利弊分析的经典题型，以下是笔者给出的一个参考答案：

Position: I have the preference that it is not a good idea to prohibit students from the use of devices that can connect to the Internet while in the class.

Reason 1: Obviously, thanks to the pictures and videos on the Internet, it is easier for students to understand some abstruse and difficult knowledge. In addition, a large number of relevant knowledge on the Internet can help students build knowledge system faster. (由于网上有关于知识的图片和视频，学生能够更好地理解艰深的知识点，同时网上大量的相关知识可以帮助学生快速建立知识体系)

Reason 2: Second, the process of searching information on the Internet can cultivate students' independent learning ability, and promote the ability to handle numerous information which plays a vital role in their success in the future. (在网上搜寻信息的过程也可以培养学生的独立学习能力，以及整合大量信息的能力)

Concession: It is true that these devices may attract students' attention, therefore, distracting them from real learning.（这是一个让步段，表明尽管互联网设配可能会干扰学生的学习，但可以通过一些网络限制或者使用时间段的限制解决这个问题）
