两者的动词时态只看is和was.其实还有可以有完成时.
used 不是形容词,而是动词的被动语态. be + 过去分词
不明白还可以继续追问

这里面的is和was分别是一般现在时和一般过去时的标志。前者的意思是这支钢笔在过去被 David使用，后者的意思是现在被使用，由于这两句话的主语都是人，钢笔是物，物被人使用，故使用被动语态。这里的used不是形容词，只是动词的分词形式。被动语态的结构就是be+done，我想强调的一点是used作动词的时候没有人称和形式的变化。...

use是动词
used是被动形态，跟is和was表示的时态是没关系的。

如果把is放在used后面，则要把定冠词the去掉，变为this pen is used by David，那这就是一个被动语态了，翻译为：这支笔是被David用的。不懂追问，祝
