单项选择题
It looks like a terrible tiger but actually, ______ of pressed paper, it softens when damp and is washed away in a heavy rain.
A．made
B．having been made
C．to be made
D．being made
答案
参考答案：D
解析：being made表示原因，不表示时间，所以B不合适；不定式表示原因多用于类似句中：I felt rejoiced to hear the news. I wept/saddened to learn that the old man died. 另外，过去分词一般不单独用来表示原因，故A也不正确。
