【答案】The pieces are ______ by hand from a very special kind of clay and then allowed to air-dry.

The pieces are ______ by hand from a very special kind of clay and then allowed to air-dry.

A. care shape B. careful shaped C. carefully shaped D. carefully shape

【答案】

C

【解析】

句意：这些零件是用一种非常特殊的粘土手工精心制作而成，然后风干。考查被动语态和副词辨析。根据The pieces are ___ by hand from a very special kind of clay and then allowed to air-dry.可知主语The pieces是动词shape的承受者，所以应用被动语态，由系动词are可知应用一般现在时的被动语态，其结构为：be+动词过去分词，shape的过去分词是shaped；又因为shaped为动词，副词修饰动词，所以前面用carefully修饰；故答案选C。
