—It ________ amazing. It's my first time to get to know this.

A. sounds B. smells C. tastes D. looks

Answer 1

【答案】A

【解析】句意：--3D打印机在不到24小时之内能够建好一个房子。--听起来真令人吃惊，这是我第一次了解到这件事的。A. sounds听起来； B. smells闻起来； C. tastes尝起来； D. looks看起来。这里it指的上面提到的那件事3D printing could be used to build a house in less than 24 hours，这件事应该是听到的。所以应该用sounds听起来，是系动词，故选A。
