It is the first time that...句式分析
■本站特约作者 刘永科
老师在讲“This is the first time that...”句式用法时，说that从句要用“现在完成时”。并且，老师在黑板上写了一个例句：This is my first time that I have visited
下面，我们分析这个句子：This is the first time that I have visited
【结构分析】
This is the first time为主句，that I have visited Beijing.为定语从句，修饰the time，that为关系副词，可以省略。因此，我们常说：This is the first time I have visited
基本句式：This (It, That) is the first (second, third) time that ...
【时态分析】
This (It, That) is the first time that...跟与现在完成时连用，这体现了“现在完成时”的另一个特点：对过去经历的总结。意味着从过去某个时间到说话时的经历总结（也可能是人一生所经历），这跟现在完成时的“动作发生在过去，一直持续到现在”有某种关联，只不过是强调次数和经历而已。例如：
This is the first time in my life that I have taken part in such a grand celebration.这是我有生以来第一次参加如此盛大的庆典。
