一、外显连接 所谓外显连接是指用特定的连接词将相关信息进行连接。通常情况下，例子作为论据由for example, for instance, like, such as, take… as 等引出。
如：it is undeniable that mobile phones have facilitated our lives in many different ways. For example, when an emergency occurs, such as a traffic accident or a violent crime, mobile phones can help the victims to call the police or an ambulance immediately for help.
本例中，for example 引出例子论证“mobile phones have facilitated our lives in many different ways.” 而后面的 such as 则引出emergency 的具体形式。For instance 与它的用法完全相同，即后面要接句子例证。 Like, such as, take…as 等直接名词（或相当于名词的词）。由于这些都是基本常识，这里不再赘述。
为了使连接词多样化，建议考生运用下面的一些短语（或句式）连接论点和句子：
…is a case in point;
…serve as a typical example
…can be taken as an example;
one example is that…
another one is that等
如：Working part time when you are studying in university is beneficial to your life. I myself is a case in point（or 'my experiences serve as a typical example'）. Through those experiences, I have learned to be independent and responsible.
