Dog is my favorite animal. The reason why I like it most is because it’s very competent. Dog is the best friend for mankind. It is also the best companion for the old people. The dog can feel the human nature. So many old people will raise dogs if their children are not with them. The old can give their love for their children to the dog to make themselves feel warmly. I believe the seeing eye dog is very famous. They are special dogs. Those dogs will guide their owners whose eyes is blind to go the correct way. See, I say dogs are very competent.

我最喜歡的動物是狗。我最喜歡它的原因是因為它很能干。狗是人類最好的朋友。它也是老人們最好的伴侶。狗是通人性的。如果他們的孩子不在他們身邊，很多老年人會養狗。老年人可以把對他們孩子的愛放到狗狗的身上，這也能溫暖他們的心。導盲犬是非常有名的。他們是特殊的狗。這些狗會引導眼睛看不見的主人找到正確的路。看，我就說狗狗是非常能干的。

題目2：There is little justification for society to make extraordinary efforts—especially at a great cost in money and jobs—to save endangered animal or plant species.The statement holds a view that the action for saving endangered animal or plant species with extraordinary efforts consumes a great cost in our nature community.It is plausible that we let nature take its course and should not take extraordinary efforts to save them in terms of the theory about survival of the fittest in nature selection.Yet,I do not stand on this position,since our government and society have obligation to protect those species being in danger.And some animals or plants closely interrelated to human beings are therefore worthy of saving even at a great cost.Previously, there was a harmonious equilibrium in our nature.Some species died out and some came in.It is all dues to the nature selection.With the industrialization progress,this balance has been broken up with the impudent exploitation of the environment.The extinctions caused by human pressures are far more swiftly than the nature rate.Thus,we should be obliged to protect them spending our time and efforts.What's more,it plays a pivotal role of keeping species diversity and completion of biological chain that save endangered animals and plants.Consider that the more species die on our planet the less diversity our biological sphere have,and the more systematic risk we get.It is also disturbing to think that we live in a planet with only few animals and plants.Moreover,I hold the point that society have to spare no efforts to revive the endangered animals and plants that are closely relative to people.In order to develop beauty and harmony in our environment we have to take actions to protect endangered species no matter how the influence human beings have.Besides,the prospect of society and the progress of technology are based on a good ecosphere with numerous animals and plants.So,it is inevitable for society to spend time and money to save endangered species as many as we can.However,it does not automatically mean that a society can unduly /unscrupulously pour money and jobs into protecting those being in danger species.Granted that the wealth and energy of a society are limited,it is impossible for the extraordinary way to put into practice.Development has to be pursued forward by a society and the wheel of living have to move on.Assume that we live in an environment with the scarcity of food to eat and lacking money to make a purchase and an instability world is around the corner, no one are willing to continue this extraordinarily saving endangered species project.In sum,at the limited extent of our ability and finance,we should help endangered species return to prospect population and then make our future better.
