3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer that provides copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego.
“The demand has been amazing. There has been a lot of interest from people. It’s been much more than I would have imagined.”
The demand has been amazing。
amazing为形容词，而不是amaze的目前分词。由于目前分词是动词，amaze作为动词是及物动词，一个及物动词需要带有宾语，语义才能完整。这里amazing没宾语，所以只能是形容词。所以这个句子是系表结构的目前完成时。该句承前省略了一个持续时间状语，即 since the store put 3D printers in three of its independently-owned stores.
(自从该商店在其独立拥有些三个店里安装了3D打印机）需要量一直都是非常惊人的。
