Ten years ago, a doctor told me something was wrong with my lung and I had to give up work at once and went to bed.

Through time, I have seen in several animal TV programs amazing examples of concern, bravery and care between sometimes dissimilar and even unfriendly species; this makes me wonder that animals are not quite 1 from the human race when faced with certain 2 .

Once, I watched a program where a lioness took 3 of an orphaned(无父母的) antelope baby; the 4 leads this lioness far away from her group, 5 that other lions would kill her unusual baby easily. After a few days, both were 6 ; the lioness was unable to make a kill 7 herself, and she didn’t have any milk to 8 to the baby. This uncommon behavior attracted the 9 of some animal protectors that decided to 10 and record in film this unnatural relationship.

In 11 case, a female hippo(河马) took away a small antelope from the 12 of a crocodile(鳄鱼); she stood beside the dying animal 13 to save his life by breathing into his mouth and pushing him 14 , forcing him to 15 and run away from the danger; she continued until the wounded antelope died.

In another 16 case, two lions saved the life of a small girl when several men were kidnapping her; they were 17 and run after by the brave lions; although they had the small child at their reach and 18 , they stood at her side for hours until the small girl’s parents arrived.

19 these attitudes may be rather natural I am sure animals can tell other creatures’ suffering and pain and be actually willing to do something to try to help. I can’t describe this behavior as a human 20 , but I think this willingness to help other suffering creatures may be natural not only to humankind, but also to some animals if a certain situation or emergency presents itself.
