现分析原题及范文如下：
In
the past, the main role of teachers was providing information. Today, however,
we can get access to a wide range of information. Thus, there is no role for
teachers. To what extent do you agree or disagree? 20170325
关于老师的话题，近些年多次在考试中出现。审题之后，相信绝大部分的考生都会否定题干中的观点。下文亦是如此。
In
the era of information, some people blindly begin to doubt whether teachers are
still as significant as before for students due to the fact that students
nowadays can be readily exposed to a huge amount of information. Those people
ought to patiently and carefully imagine what would happen once teaching
profession totally disappeared.
首段，其实只是通过了一个伴随状语介绍了全文的背景（这是一个信息时代），随后就主观地进行了点题。
主观点题的意思就是在点题的同时，使用一些带有主观色彩的词汇来表达笔者的立场，如blindly等。开头段第三句话的根本作用是引出下文，并非所有文章都需要这样的承接下文的句子。
To
begin with, parents would hardly know whether their children go to school or
not. Without teachers' maintaining school discipline, students were more likely
to spend their time doing things that can arouse their interest. Unluckily, in
most cases, what those students would do is completely not related to their
study. Worse, playing truant would be a common choice for most of them.
第一段，重点强调了一个没有老师的世界的恶果。整段（乃至全文）都是反正法，通过假设老师这个职业已经在社会上消失，来推断后果。因此，全文论证多次使用虚拟语气。
On
top of this, even though some students chose to stay at school to learn, they
could merely learn a little without teachers' assistance. Information they can
obtain is always unordered and even with errors, so that they need someone who
is able to help them organize and filter what they plan to learn. Undoubtedly,
experienced teachers are the best persons providing help for those students
struck in troubles in their study.
承接上一段，进行第二个恶果的推断。
Ultimately,
future of those students would be thoroughly ruined assuming that no teacher in
school could give them moral education. Misleading information and distorted
value system might easily bring students extremely negative consequences. It is
convincing that some of them would have misconducts or unhealthy life goal.
Thus, the future they might have would be totally different from what they and
their parents expected.
再次推断第三个恶果。本文为一面倒式的论证，不包含任何的让步段落。
In
general, what teachers can do is far more than simply providing information for
students, and hence in this day and age by no means should significance of
teachers be ignored. Society without teachers would be what neither students
nor their parents could stand.
