sparent to solar radiation, like clear air. So they mostly transmit ining solar energy down to earth. There is not much reflection going on at all. At the same time, these clouds trap in some of earth’s heat. Because of the trapped heat, these clouds have an overall heating effect. Male Student Oh, OK, so since low thick clouds are not transparent to radiation… Professor Exactly. They block much of the solar energy so it never reaches earth’s surface. They reflect much of it back out into space. Female Student So that’s how clouds contribute to cooling? Professor Yeap, and as I said earlier, this cooling effect predominates。 now what If there was a process that could control the types of clouds that form? Male Student Are you talking about controlling the weather? Professor Well, I am not sure I’ll go that far. But we recently noticed an increasing cloud cover over an area of the ocean waters around Antarctica. An increased area of low thick clouds, the type that reflects a large portion of solar energy back to space and cools the earth. Well, the reason for this increased cloud cover, it turns out, is the exceptionally large amount of microscopic marine plants. While the current hypothesis is that these microanisms produce a chemical——Dimethyl sulfide that interacts with the oxygen in the air, creating conditions that lead to the formation of the low thick clouds we’ve observed. Well, if that’s true, it could have huge implications. So maybe we are talking about controlling the weather. Conversation 2 Narrator Listen to a conversation between a student and his English professor Professor Hi, Bob, how’s it going? Are you enjoying the introduction to literature class? Student Yeah, it’s great. Araby, that short story by James Joyce we read last week. It was awesome. Professor Glad you liked it. Most of Joyce’s work is very plex. A lot of students say that it’s hard to understand. Normally, you wouldn’t tackle Joyce in an introclass but I like to give my firstyear students a taste of his style, his psychological approach to literature because, well mainly because it influenced other writers. I only wish we had more class time to discuss it. Student Me too. So why did you pick Araby instead of some other story? Professor Well, first you should know that Araby is one of fifteen short stories by Joyce in a book called Dubliners. All the stories are related to one another and are set in the same time period but Araby is the easiest one to follow. Though all the stories in the collection are written in stream of consciousness, which, as you know, means they are told through the narrator’s thoughts through an inner monologue as opposed to dialogue or an objective description of events but Araby is easier because it’s linear。 the story unfolds chronologically. Student Still, I wish we could read whole novels by Joyce and discuss them in class. Professor That’s what happens in my master writer class. Student Master writer class? Professor Yeah. I teach one on Joyce every spring. It’s such a privilege, spending an entire term delving into a single body of work and my students, they bring so much insight to the table that it’s easy to fet who the professor is. Student Oh, wow, that could actually solve my dilemma. What I originally wanted to ask you. I am working on my schedule for next term and I got room for one more course and I’d like to take more literature. Could I take the master writer class on Joyce? Professor Oh I am sorry I should have mentioned. Master writer’s an advanced seminar. So students need to get a strong foundation in literary theory and criticism before I let them enroll Student But I’ve got really good grades on all my paper so far I am sure I can keep up. Couldn’t you make an exception? Professor Your grades are excellent but in our intro class, you are reviewing the basics like plots, setting and character and getting your first real exposure to different literary styles Student But why do I have to study different styles to understand Joyce’s novels? Professor There are a lot of little details involved in interpreting literature, and like with Joyce, his novels have very unique structures, the only way to appreciate how unique they are is by。
