2.Some drug makers and other companies put three-dimensional images called holograms (全息图) on their products as a security device.

[翻译]一些药物生产商和其他公司在他们的产品上放上被称为全息图的三维图片作为安全装置。

[分析]本句中的过去分词短语called holograms (全息图)作为定语修饰前面的名词three-dimensional images，因为两者之间构成被动关系，所以使用过去分词。相当于定语从句which are called holograms。

1.People could send a text message with the code and get a message back, which proves that what they bought is listed in a database.

[翻译]人们可以发生一个带有密码的短信，然后会收到一个回复的短信，这个短信证明他们所购买的是在数据库里所列出来的。

[分析]本句非常复杂。本句中的which引导的是一个非限制性定语从句，which指代前面的message在定语从句中做主语，同时对于从句中有一个that引导的宾语从句，这个宾语从句中有一个what引导的主语从句。
