Western Philosophy

Today I had western philosophy's test. Western philosophy's content is logical formulate. The teacher said "Philosophy is a kind of wonder or refusal to take things for granted. The first class, the teacher told us, "Caesar invaded Gaul. Thrush's eggs are blue. Two and three make five." This sentences mean declarative sentences. Next, "Polly, put the kettle on." This sentence is an imperative sentence. "O to be in England, now that April's there." This sentence is desire. Who is Sylvia? This sentence is an interrogative sentence. "If Eclipse wins the Derby, then I shall be rich." I can't understand what this sentences meaning, but teacher told, these are proposition. We can make sure of the truth of the matter. I thought, I can't understand the meaning, so I can't make sure of the truth of the matter! For example, this is a question. Snow is white. True or false? This answer is 'Snow is white' is true, if and only if snow is white. I get still worse. I can't catch up with the class. And also I am afraid that there is a possibility of losting credit. Maybe I will not take the class next semester.
