English for Environmental Engineering,I Description of Course: credit:1.8 duration of course: 8 weeks test mode:exam (20%+80%) (20%=translation excises +mini-project+attendance) II Description of Lecturer quality-20 working years experience in environmental science and master degree in environmental management as well as top 1 translator for environmental science in Chongqing.,Personality-friendly, simple, hardworking, hate any forms of cheating ,I prefer being your friend rather than your teacher. Expectation for studentsyou can change your attitude on studying English, from disliking English to enjoying English . III How to make use of this course? Goal: improvement of reading, translation, writing and presentation skill in English for environmental science Focus for Each Chapter: -new words and expressions,-access to background knowledgy on each chapter -understanding of concepts involved in each chapter -questions and discussions realated to topics in each chapter -translation exercise,Types of activities: learning-based classes, case study, workshop, translation exercise, watching video related to environmental issue. Briefing final examination 1)everyone can pass if you keep notes in the classes no matter whether you are good or poor in English; 2)for several students who often are in the absence of classes, I will intend to make them fail exam unless you can do very well in the exam.,IV Recommendations on how to improve your English ability for environmental science -Transfer from grammar-oriented reading to applied English -preparation of an English dictionary for environmental science -regularly visit environmental website and access to environmental information http:/www.ends.co.uk ,-Learning new words in the readings rather than remembering new words individually -practice your presentation skill through workshop V Testing your existing English ability for helping my understanding your English level Translations: 1 Evidence shows that poverty-related urban environmental issues tend to improve as the economy develops and income grows,2 These impacts include overconsumption of resources, loss of biodiversity, increased amounts and treatment of municipal wastes and increased CO2 emissions. 3 Professor G.
