【题目】Poor boy! His _____ looks and _____ hands suggested he was very afraid.
A.frightful; trembling
B.frightened; trembling
C.frightening; trembled
D.frightened; trembled

【答案】B
【解析】句意：可怜的孩子！他害怕的表情和颤抖的双手暗示着他很害怕。此句中的look是名词表示表情.当修饰表情等词时用＋ed形式,tremble是不及物动词,是颤抖的意思.与被修饰词hand 是主动关系所以用动词ing形式,在句中作定语.，故选B项。
