单选题 Music is part of the structure of our society; it sits at the heart of human experience and enriches (丰富) so many lives. Why, then, is it not central to our education system? This is a question I recently put forward to an all-party group on music education. I am 20 years old and began playing the piano at the Barracudas Band in Barrow-in-Furness, aged seven. The funding for the centre has now been cut. I took part in the primary tuition project, aged 11. The funding for that has also been cut now. It is a common problem across the country. Music is not an add-on, a 'soft' subject or a luxury—it is absolutely essential to our existence. Every child deserves the opportunity to experience its benefits. Until music is held in the same regard as the 'core' subjects of our curriculum, our society will be worse off. We need joy, empathy (共情) and hope on this planet more than ever, and taking away children's opportunity to develop musical skills is to set ourselves up for a fall. Despite the many brilliant programs and projects to encourage young musicians ('Every Child a Musician,' 'Awards for Young Musicians,' to name but a few), we are reaching a crisis point. We are in danger of destroying creativity, innovation (创新) and expression. Learning an instrument can help develop so many fundamental life skills. It promotes discipline, empathy, determination and cooperation as well as providing a sense of community and worth. Music has changed my life. It is a huge part of who I am. I have learned so much about the world through music and the inspiring figures I have met through it. I feel I have a duty to help ensure that others can benefit from its magic. Let us make it available to every single child.

单选题 Vegans try to live, as much as possible, in away that avoids exploiting and being cruel to animals. This means following a plant-based diet. Vegans do not eat animals or animal-based products like meat, fish, seafood, eggs, honey and dairy products such as cheese. For many vegans, living a committed vegan lifestyle means not wearing clothes made from animal skins and avoiding any products which have been tested on animals. Vegans argue that suffering is caused in the production of these foods. For example, they say that, on some dairy farms, male calves (小牛) are killed because they are too expensive to keep, and cows are killed when they get older and produce less milk. As for honey, vegans say that bees make honey for bee, not for humans, and that bees' health can suffer when humans take the honey from them. Vegans believe that the products they use and consume should be free froth not just cruelty but any exploitation of animals. The main reason for going vegan is probably that they believe animals and all other sentient (有感知能力的) beings should have the right to life and freedom. However, there are other reasons. Vegans argue that the production of meat and other animal products is very bad for the environment. They point out that a huge quantity of water is needed to grow grain to feed animals in the meat industry. The enormous amount of grain which the meat industry needs often leads to forests being cut down and habitats (栖息地) being lost. In contrast, much lower quantities of grain and water are needed to sustain a vegan diet. In addition, many vegans say that all the nutritious elements our bodies need are contained in a carefully planned vegan diet and that this type of diet helps prevent some diseases.

单选题 For some time past it has been widely accepted that babies and other creatures learn to de things because certain acts lead to 'rewards'; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological 'drives' as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise. It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome. Papousek began his studies by using milk in the normal way to 'reward' the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement 'switched on' a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result. For instance, two left or two right, or even to make as many as three turns to one side. Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would 'smile and bubble' when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.
