你好:Since the 14th and 15th centuries, the Diaoyu Islands have been included in Chinese maps.
自十四十五世纪以来,钓鱼岛一直就是中国的领土(在中国的地图上).
分析如下:
(1)先弄明白什么是过去完成时.过去完成时表示过去的过去,即有一个过去的时间点,在这个点之前的动作就用过去完成时.本句the Diaoyu Islands have been included in Chinese maps动作发生在前一个时间点的后面,所以用现在完成时.下面是一个过去完成时的例子,一般以时间状语从句的形式出现:Before I went home, he had finished his homework.
(2)常见的现在完成时的时间状语有:for+一段时间(如a week, a year等), before,already, since+时间点(如last week, 2010, the 15th century等),当然还有其他一些词.
希望对你有所帮助.

1、若since引导的状语从句的谓语为持续性动词的现在完成时,则表示动作和状态延续到现在,其表示的时间的起点应从动作发生之时算起,因此此题用have been included
2、句子的翻译:从14、15世纪钓鱼岛一直包括在中国地图中

.have been included是现在完成时,是指从过去某个时刻开始一直延续到现在。
had been included 是过去完成时,是指从过去的过去某个时刻开始一直延续到过去。

二者时间起点不同,A是现在完成时,是过去发生某事,并且对现在造成影响,从14th一直现在都是在中国地球上的。而B是过去完成时,是过去的过去对过去的影响,如果选B那后面内容的发生时间就应该对现在来讲也是过去。

楼主你好,
A.have been included被包括到中国地图中。是到现在此刻为止都在中国地图中。
B.had been included同意,但是此指过去有一个时间点,比如18世纪,从14、15世纪到18世纪一直是包括在中国地图中,而现在21世纪,已经不再中国地图中。
根据实际,钓鱼岛一直是中国的固有领土,自然一直都在中国版图中。
