阅读下面的材料，根据其内容填空，完成后面的文。
They’re best friends. They are together every day. One of the friends, Jenny Siegle, is in a wheelchair (轮椅). The other, Augie, is a dog and he helps Jenny. 14-year-old Jenny is a quadriplegic (四肢瘫痪者). She cannot use her arms or legs well. Augie is not only a dog but also Jenny’s arms and legs.
How does Augie do this? In school, he picks up the pencil or notebook that Jenny drops. Jenny is also training Augie to pull off her jacket so Jenny doesn’t have to ask others for help.
At home, Augie brings her newspapers. He even helps clean Jenny’s room. When Jenny asks him to do something he can’t do, Augie goes to get her parents or sister.
At the mall, Augie wears a coat which tells everyone he is helping Jenny. After Jenny buys things, Augie carries them to the counter (柜台). He gives the cashier Jenny’s wallet and waits for the change.
The lovely and friendly dog is also a social bridge. Other kids may not know Jenny. But they come up to talk to her because they think Augie is interesting.
Augie is truly Jenny’s best friend and her bridge to the world.
