单项选择题
I can still vividly remember to pick our steps in the mountain down the deep valley on my 21 st birthday.
A．picking.., in the mountains
B．picking ... on the mountain
C．having picked ... from the mountains
D．picking ... from the mountains
答案
参考答案：D
解析：[分析] 结构应用及习惯搭配。 动词“remember+动名词”表示“记起过去做过的一件事”，“remember+不定式”表示“记住要去做某一件事”：本句意为“我仍能清楚地记得……”，所以应用动名词。第二个空白处因是表达“小心地沿深谷下山”，所以是pick our steps from the mountains down the deep valley，选项D正确。
