It was()to see the students' excitement when they discovered that simple materials could be used to cook food under the sun and the solar cooking really attracts those creative kids.
A. amazing
B. amazed
C. amaze
答案:A
解析:本句意思:当学生们发现简单的材料可以用来在太阳下烹饪食物时,他们的兴奋之情(令人惊讶),而太阳能烹饪真的吸引了这些有创造力的孩子们。系动词be后是表语,所以不用原形amaze;作表语时,如果主语是事件,多用ing形式,同时表示主动关系;如若主语是人,多用ed形式,同时表示被动关系,所以选A。
