题目内容
1.The producer comes regularly to collect the cameras_____ to our shop for quality problems.( )A. | returning | B. | returned | C. | to return | D. | to be returned |
分析 厂家定期过来回收因质量问题被退回的照相机.
解答 动词return与其逻辑主语the cameras之间构成被动关系,故用过去分词的形式done,所以选B.而A选项doing表示一个主动的或正在进行的动作;C选项to do表示一个将要发生的动作;D选项to be done 表示一个将要发生的被动动作; 故ACD都不选.
点评 此题考查非谓语动词作定语.非谓语动词作定语的基本原则是:to do/to be done 表示动作尚未发生;doing/being done 表示动作正在进行;done 表示动作被动或完成.
