单选题Brendan"s best friend is Tip. Tip and Brendan are inseparable. They teach each other things and they look after each other. Tip has helped Brendan become more responsible, more caring, and a better friend. Brendan is a nine-year-old boy, and Tip is a ten-year-old dog. Brendan and Tip are an example of how owning a dog can have a positive effect on a child"s development. Having a dog develops a child"s sense of responsibility, broadens his capacity for empathy, and teaches the nature of friendship. Having a dog helps a child learn how to act responsibly. As a dog owner, the child must take care of the animal"s daily needs. The dog must be fed and exercised every day. A dog is completely dependent on its owner for all its needs, including the need for good health and a safe environment. Therefore, being responsible for a dog also means taking care of the dog so that it stays healthy. Furthermore, the owner must take responsibility for the safety of the dog and the safety of the people it comes into contact with. If the child forgets any of these duties and responsibilities, or ignores any of the dog"s needs, the dog will suffer. This teaches the child that his responsibility to the dog is more important than his desire to play with his toys, talk on the phone, or watch TV. This is true not only for the care of a dog, but also for the care of oneself, another person, or one"s job. Learning how to take responsibility for the health and welfare of a dog leads to learning how to take responsibility for oneself. Another lesson that a child can learn from having a dog is how to be empathetic. Empathy is the ability to put oneself in another person"s, or in this case, another creature"s, situation and imagine that person"s or creature"s feelings or problems. A dog cannot express itself with speech, so its owner must learn how to interpret its behaviour. The child must learn to understand what the dog"s behaviour means. Is the dog frightened, aggressive, or sick? The child needs to understand what is going on in the dog"s mind. Understanding a situation from the dog"s perspective helps the child understand why the dog is behaving in a certain way and what the dog needs. The result of learning to read a dog"s behaviour is that the child develops empathy. By learning how to empathize with a dog, the child also learns how to empathize with other people. This leads to the child becoming a more considerate and caring person. Being considerate and caring are important characteristics in a good friend. One of the most significant benefits of owning a dog is the example of true friendship that a dog provides. A dog gives unconditional love to its owner. A dog will not stop loving its owner because of a little anger, indifference, or neglect. The dog will patiently for its owner to pat its head and say a few kind words. This acceptance of the negative qualities and appreciation for the positive qualities of its owner provide a wonderful model of how to be a good friend. A child soon realizes that his dog will always listen to him, will always be ready to play with him, will always protect him, and will always forgive him. A child who has learned to be even half as good a friend to others as his dog is to him will have learned of the most valuable lessons in life. These are some of the most important lessons a child will ever learn. The benefits of owning a dog will last the child"s entire lifetime. The understanding and appreciation of responsibility, empathy, and friendship that a child develops from the experience of having a dog will help him or her grow into a reliable, caring, and mature adult.

单选题The European Union revealed on January 23rd how it plans to save the world. A mammoth climate-change plan spells out in detail how much pain each of its 27 members will have to beat if the EU is to meet ambitious targets set by national leaders last March. The aim is to cut greenhouse-gas emissions by 2020 by at least a fifth, and more than double to 20% the amount of energy produced from renewable sources such as wind or wave power. If fuel from plants proves green enough, 10% of the fuel used in transport must come from biofuels by the same date. The new plan turns these goals into national targets. This will surely start much grumbling and months of horse-trading, as the European Commission"s recommendations are turned into binding law by national governments and the European Parliament. Countries with greenery in their veins are being asked to take more of the burden than newer members. Sweden, for example, is being invited to meet 49% of its energy from renewables. At the other end, Malta gets a renewables target of just 10%. It is a similar story when it comes to cutting greenhouse gases; by 2020, Denmark must cut emissions by 20% from 2005 levels; Bulgaria and Romania, the newest members, may let their emissions rise by 20%. EU leadership on climate change will not come cheap. The direct costs alone may be C 60 billion ($87 billion), or about 0.5% of total EU GDP, by 2020, said the commission"s president, Jose Manuel Barroso. But this is still presented as a bargain compared with the cost of inaction, which Mr. Barroso put at ten times as high. "Oh, leading the world in the fight against climate change need not cost jobs. Even in the most heavily polluting branches of heavy industry. We want to keep out industry in Europe," insisted Mr. Barroso. The trick to achieve the seemingly impossible targets is the EU"s emissions-trading scheme (ETS). This obliges big polluters such as power companies or manufacturing giants to trade permits that allow them to emit CO2 and other climate-change nasties, within a steadily tightening overall cap. If countries such as the US do not sign binding international agreements by 2001, then the heaviest greenhouse-gas emitters inside the EU may be given these allowances free, the commission suggests. Or, it threatens, firms to buy ETS permits.
