Unit Two Task 1 Familiarizing Yourself with Classification
1) Man-made or anthropogenic causes, and natural causes.
1. Skim the following passage for the answers to the questions below.
2) Pollution (burning fossil fuels, mining coal and oil, etc.), the production of CO2 ( the increase of
population, the demolition of trees, etc.) 3) CO2 is a greenhouse gas that traps heat in the Earth’s 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.

4. Listen again and piece your notes together into a short summary. Then retell the lecture to your partner.
There are two interesting ideas in Freud’s 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 person’s 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.
