According to the passage, which of the following would NOT be offered by this walking?
A. Visiting the seashore and farmland.
B. Exploring famous trails in the history.
C. Barbecuing while picnicking in the forest.
D. Having a swim while resting.
请问老师:
Barbecuing while picnicking in the forest.和Having a swim while resting 看不懂,为什么都是动名词Barbecuing和Having开头,而后面却用了while?句子还原是Barbecuing while (you are) picnicking in the forest.吗?好像不合理,while前面怎么可以是动名词形式呢?
