-_Unit TwoTask 1Familiarizing Yourself with Classification1. Skim the following passage for the answers to the questions below.1) Man-made or anthropogenic causes, and natural causes.2) Pollution (burning fossil fuels, mining coal and oil, etc.), the production of CO2 ( the increase ofpopulation, the demolition of trees, etc.)3) CO2 is a greenhouse gas that traps heat in the Earths atmosphere.4) Classif ication helps us to determine and understand the relationship of the parts of a subject which is studied by us. Classification is made on the basis of a clear definition.5) In order to make a clear and logic classification, one needs to follow a principle of classification and go on with a system consistently. For example, the categories of classification should be mutually exclusive and no overlapping is allowed.Reading 1Causes for Global WarmingTask 2Understanding Lectures through ClassificationListening 11. Listening to the lecture and write down whatever you believe is important, especially theclassifications of key terms.Unconscious motivation, unconscious conflict, the id, the ego, the superego, etc.2. Use your notes. Decide if the statements below are true (T) or false (F). Then justify your answers, in the space provided, by giving evidence from the talk.1) T2) F3) F4) F5) T6) F7) T8) F3. Listen again, paying attention to the following classifications and then complete the tables below.Idea One: The existence of an unconscious motivationIdea Two: The notion of unconscious dynamics or conflict4. Listen again and piece your notes together into a short summary. Then retell the lecture to your partner.There are two interesting ideas in Freuds theory: first, the existence of unconscious motivation; second, the concept of unconscious conflict. Freud believes that unconscious motivation might play an important role in a lot of situations, such as marriage, forgetting a persons name, calling out the wrong name etc. In his view, there are three processes going on in the head, namely, id, ego and superego, which are in violent internal conflict. Id functions on“the Pleasure Principle”, while ego works on “the Reality Principle”and superego is the internalized rules of a society. Ego is in between id and superego.Task 3Reading Classification ArticlesReading 2Renewable Energy SourcesA Brief Summary1. Work with a partner or a group of 34 students.
