原文：And I am the professor of children’s literature at Newcastle University. And I want to write a very short introduction to children’s literature because although, here in Britain, we have one of the longest and most distinguished traditions of creating books for children, perhaps the longest and most distinguished in the world, we often take them for granted and we don’t pay enough attention to what a remarkable cultural resource they are for adults and the kind of cultural work they do for children and the way that they have served writers and illustrators as a cultural space for creativity subversion and opportunities to experiment with new ideas. So what kind of cultural work the children’s books do? Well, at the level of individual child, this is one of the places where children learn the vocabularies, get the vicarious experiences, and see the images of the world that help them think about how the world works and where they fit into it. Because children’s books are one of the first places that children encounter these things, they are often very direct as a source of information about what a particular period thinks, including what it thinks a child is, what a child needs to know, what childhood looks like. Sometimes when we are looking at children’s books from the past, that’s very important to notice the kinds of children who aren’t there, for instance. So, that is one of the things that we have in children’s books.
Britain has the longest tradition of creating books for children. However, we often take children’s literature for granted and overlook that they are remarkable cultural resource for adults and children and that they served writers as cultural space for creativity and experiment with new ideas. Children can learn vocabularies and experiences, and see the world from children’s literature. Children’s literature can also inform what a particular period thinks.
原文：To understand the Fight or Flight response, it helps to think about the role of emotions in our lives. Many of us would prefer to focus on our logical thinking nature and ignore our sometimes troublesome emotions, but emotions have a purpose. Our most basic emotions like fear, anger or disgust are vital messengers: they evolved as signals to help us meet our basic needs for self-preservation and safety. It would be dangerous to be indecisive about a threat to our survival so the brain runs information from our senses through the most primitive, reactive parts of our brain first. These areas of the brain control instinctive responses and they don’t do too much thinking. This more primitive part of our brain communicates with the rest of our brain and our body to create signals we cannot ignore easily: powerful emotions and symptoms.
Understanding the fight or flight response helps to understand the role of emotions. Many people focus on logical thinking and ignore emotions, which have purposes. Basic emotions evolved to help us with self-preservation and safety. Our brain runs information from senses through primitive part of brain first. These parts of the brain, which control instinctive responses, communicate with body to create signals, which are emotions and symptoms.
原文：So happiness economics can help us get to these questions, and I’ll try to give you some examples of this. Now, even though there’s a lot of skepticism, originally about using this survey – surveys what people say make them happy. The number of reason that we are getting increasingly confident in doing so. One is that their consistent pattern – remarkable consistent pattern, determines well-being across large samples of people, across countries, across the world, and over time. Some of the basic things that make people happy, and I will show you some of these income, health, marital status, employment status. Some of these very basic things are remarkably consistent across countries across world. So that gives us some sense that these surveys are picking up consistent patterns. And when we know what consistent patterns are, we can look how other things that very much more, affect people’s well-being. The environment and equality, the nature’s institution raging on living, and all kinds of other things that very much more.
The lecture is about happiness economics. There are some skepticisms about the survey of what make people happy. There are some reasons that the speaker is confident in the survey. Firstly, the study shows consistent pattern which determines well-being across large samples of people. These include income, health, marital status, and employment status(这部分听不到可以不写). The speaker is now intended to look how other things affect well-being.
原文：The aperture of a telescope is several times larger than the aperture of human eye so that the objects that can not be normally seen by unaided eye can be seen. Light-gathering power of a telescope is proportional to the area of its aperture and hence depends on the square of the radius of the mirror. Therefore, a 20 cm diameter telescope collects four times more photons than a 10 cm diameter telescope. A telescope can be equipped to record light over a long period of time, by using photographic film or electronic detectors such as photometers or CCD detectors while the eye has no capability to store light. A long-exposure photograph taken through a telescope reveals objects too faint to be seen with the eye, even by looking through the same telescope. A third major advantage of large telescopes is that they have superior resolution, the ability to discern fine detail. Small resolution is good. The resolution is directly proportional to the wavelength being observed and inversely proportional to the diameter of the telescope.
