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.
with their chattering when they fly
with chattering and its flying
by chattering as it flies
by chattering and its flying
by chattering as they are flying
主语是the bird 所以是单数,排除A&E
通过什么方式用by,而且我个人觉得如果用with可以引起歧义,因为可以和nest连接,排除A&B
as做“当”讲
D项and its flying 没有对象和其平行
