　　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(最典型为 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.

　　在连接词的学习当中，我们需注意理清连接词的四类词性及各词性用法，然后把不同关系的连接词根据词性进行整理，并广泛仔细的参考高分范文尤其是考官范文当中的优美句式，连接词这一块的分数是值得期待的。
