雅思作文中的连接词，阅读可以判断当方向词的转折，口语可以当coherence连贯性的重要部分，听力中的障碍物
·连词
如but, and,后接句子，连接并列句时前面逗号可有可无。当然连词也可放句首，这一点在考官范文里有很多体现。
例：In the past, populations were partly regulated by frequent war and widespread disease, but in recent years the effects of those factors have been diminished. (并列句中的连词)
段落开始： But how should it be achieved·( 连词放句首)
·介词
如before, despite：后接名词或动名词
例：Before talking about the essential role of death penalty, you have to think about the meaning, and the purpose, of any kind of punishment.
·副词
·递进关系
1. moreover/ what’s more/ furthermore/ besides/ in addition (副词)
2. in addition to/ besides/ apart from (介词)
例: Apart from these tensions caused by cultural differences, international tourism may also lead to conflicts between tourists and a local community. (可代替词汇：in addition to, besides)
·让步关系
1. although/ though/ even though/ even if/while (连词)
2. in spite of/ despite (介词)
3. no matter how/when/ what (连词)
例： In spite of this, the obvious benefits of computer skills for young children cannot be denied.
They are allowed to buy whatever they want, no matter how much it cost (考官高分句式)
学生学习和教师授课时，可根据以上方法对不同的关系词(如表结果，目的的连接词)进行归类。
翻看考官范文，我们发现当中有些副词(超典型为 for example, however, therefore)放在句子中间，前后用逗号隔开，这种句式也是相当的经典。例如：
There is, however, another problem way of defining that part of the quotation.
I think, therefore, that governments need to raise this awareness in the general public.
They will, for example, be able to fly planes and they will be able to co-ordinate the movements of several planes in the vicinity of an airport.
