四、信息还原(六选五)
"You are what you eat," as a saying goes. This is really true for the giant panda. What pandas eat has a big influence on many different parts of their lives.
(1)
Pandas also have really small babies because of their food. Baby pandas are born helpless and tiny. (2)
The black-and-white fur of pandas may help them to hide. Once again, we can look at a panda's food to help understand the reason. In winter, many animals lose their darker fur and grow white fur. But since pandas are always moving around to look for bamboo, they can't change their fur quickly enough to match their background like other animals can. (4)
In the past, pandas lived in and travelled across large places and faced lots of predators(捕食者). So, at that time, their black-and-white fur was very important for them to keep safe. (5)

The main danger to pandas is not from predators, but rather from less bamboo, more human activities and climate change. The good news is that pandas are no longer known as endangered, only vulnerable(脆弱的).
