在雅思写作备考中，如何进行有效的备考呢，很多考生无从下手，不知如何备考写作才有效，为帮助大家备考，小编为大家带来了雅思大作文范文解析详解，大家可以参考一下，也希望能帮助到大家。
考题如下：
Public transport should be funded by the government so that it can be free for the people who use it. To what extent do you agree or disagree? 20181101
审题之后不难看出，题干的前半句和后半句用so that链接，是一个非常典型的结果状语从句。也正因如此使得很多考生不太清楚这个道题的讨论重点是什么，是前半句的原因，还是后半句的结果。其实题干中出现这种因果关系的时候，我们可以将其简单地分成两类。
1.有明显的背景
Children can learn effectively from watching television. Therefore，children should be encouraged to watch television regularly both at home and at school. To what extent do you agree or disagree? 20170318
上题中的第一句明显是个背景的介绍，因此这道题的讨论重点自然就是题干中的第二句。类似的题目还有：
The news media has become more influential in people’s lives. Some people, therefore, think it is a negative development. To what extent do you agree or disagree? 2016023
Detailed description of crimes on newspaper and TV can have bad consequences on society, so this kind of information should be restricted on media. To what extent do you agree or disagree with this statement? 20170525
Nowadays more and more people are using cell phones and computers to communicate with others. Therefore, they are losing the ability of face-to-face communication. To what extent do you agree or disagree? 20161126
在仔细读题之后，考生们很容易就能区分开题干中的背景信息，进而就可以明确知道该题目的讨论重点是什么。
2.没有明确背景的
这类题就比较讨厌了，题干中并没有明确的背景信息，考生们不太容易判断该题目究竟是原因和结果一块讨论，还是只讨论结果即可，例如本文最开始的11月01日的考题。其实，各位不必多虑，也不必纠结。首先，这类题目中的因果关系往往都是塑料因果关系，经不起推敲。其次，为了以保万全我们在文中就题干的原因和结果分别展开讨论，这样肯定十分对题而不可能出现偏题。
见下题：
It is not necessary to travel to other places to learn about other cultures, because we can learn from books, films and internet. To what extent do you agree or disagree? 20171005
面对此题，考生们肯定能够明确前半句是一定要重点讨论的，但是后半句这个原因状语从句呢?讨论它总比不讨论的好。
下题也是如此：
Maintaining public libraries is a waste of money since computer technology is now replacing their functions. To what extent do you agree or disagree? 20161008
电子阅读是不是能完全取代图书馆的功能是一定会出现在文章当中的。因此，类似这类题目，我们就将这个因果关系看成是题干需要我们讨论的两个题干观点。分别讨论，分别总结。
Public transport should be funded by the government so that it can be free for the people who use it. To what extent do you agree or disagree? 20181101
本题例文如下：
After realizing how much money people pay for their transportation monthly, some of them call on governments to heavily finance public transport system, and others even suggest that the system should be fully funded by governments so it can be free of charge for every user. However, from my perspective, a system like this must be a thankless one.
开头段，不仅介绍了背景，点明了题目。笔者还强调了自身的立场。
While discussing whether a city needs a free public transport system or not, we have to put sufficient emphasis on some possibly unwelcomed outcomes caused by it. Chiefly, supposing we already had a system like this, almost every day I would certainly take bus for 1 hour to go shopping in a far-away but cheap supermarket where I could save 20 or 50 Yuan for a daily shopping. This is to say, this kind of traffic demand is definitely unnecessary, and it can be greatly stimulated by the free system. As a result, more social resources such as transport infrastructure would be unduly used. On top of this, investing and remaining this system must be fairly costly, imposing unbearable financial stress on governments.
主一段：笔者着重讨论题干中的结论，既我们需要不需要一个完全免费的公共交通系统。
Instead of funding the system fully, governments are supposed to subsidize it more appropriately. The funding from governments should be utilized for keeping the fare reasonable and especially acceptable for low-income population such as the unemployed and minors. An instance in point is that in most countries students under 18 can buy some discount tickets for airlines, trains, buses and subways. The subsidy provided by governments makes the system more affordable by every public transport user.
主二段，笔者重点讨论题目中的原因，既公共交通系统需要不需要政府的资助。
In conclusion, although we do not need free public transport since it might cause plenty of adverse problems to us, the governmental subsidy is still imperative.
本文两个主段就分别讨论了题干中的结果部分和原因部分。因此，本文的结论非常清晰易懂。此文为该题目N多可行解题思路之一，供大家参考。
