A、You can climb its mountains several times without difficulty in one day——as once a time.
B、You can climb its mountains several times without difficulty in one day——as I have done many times.
C、You can climb its several mountains without difficulty in one day一as I have done many times.
D、You can climb its several mountains without difficulty in one day——as I have done once a time.
【正确答案】：C
【题目解析】：ease指“轻松，自在”，在此climb with ease是指“不费力气就可爬上...”，句尾several of its mountains也即its several mountains，在此作动词climb的宾语。由此可知选项A、B不正确。题干可理解为：就像我以前多次做得那样，你可以在一天内轻松地爬上它的好几座山。many a time在此形容次教之多，意为many times,而并非选项D所说的once a time。因此答案为C。
