6.Some people argue that animals should be trained to help or entertain humans,do you agree?What is your opinion?What can be done to prevent the cruelty to animals?

of course ,i don't agree with that. the animals are human's friends.we should take care of them,but not hurt them.if there is no animal ,the eco-system of the world will be damaged seriously.
we should adopt series of practial meansures to improve the current situation.
firstly,it is urgent to create nature reserves.
Secondly, certain rare wild animals that are going to be extinct should be collected, fed and reproduced artificially.Some, known as keystone species, play a role in ecosystems that seems out of proportion to their number, such that even small changes in their abundance may have great impacts on the ecosystems in which they live.
last not the least,those who hunter them must be punished severely.according to the law in our country,in violation of the provisions of this Law, sells or purchases wildlife under special state protection or the products thereof, and if the circumstances are serious enough to constitute a crime of speculation or smuggling, he shall be prosecuted for criminal responsibility according to the relevant provisions of the Criminal Law. all relevant depatments must strictly abide by the laws.
with the joint efforts of the government and the whole community,i believe we can creat a world which humanity and animal get on well with each other.
