12. GWD21-Q12:
Birds known as honeyguides exhibit a unique pattern of behavior:  the bird leads another animal, such as a honey-badger or a human, to a bees’ nest with their chattering when they fly ahead; after the larger animal takes honey, the bird eats the wax and bee larvae.

A.    with their chattering when they fly
B.    with chattering and its flying
C.    by chattering as it flies
D.    by chattering and its flying
E.    by chattering as they are flying
答案是C，但是OG里明确了as的两种用法呀，一个是介词：capable in doing；一个是连词表像...（这里明显不应该表示像）；个人倾向选B,求解释...

Gail小M

for C, as means "during, when"

one's doing 不对，their /they在这里没有指代，注意哦，不能指代最最前面的birds,离得远而且有逗号地说，而且，B：and-------ving  and ones' ving这个不并列呀，前面是动名词简单理解相似动词，后面有名词所有格相当于名词，动名词与名词不并列。。
而且这题B还考with 独立主格。。。。。。。。
