EXPOSITORY SPEECHTopic: MTBE (Methyl Tertiary Butyl Ether) IssuesGeneral Purpose: To informSpecific Purpose: To inform audience about the MTBE and why government considered it is important to blend in gasoline.

Central Idea: The air that we breathe is contaminated by pollution from auto emissions; therefore scientists discovered a new solution to reduce air pollution is called MTBE.

I.IntroductionA.In our modern world with advance technology, most of us use automobiles as our primary transportation to work and to school. Most of us know that air pollution is mostly caused by automobile emissions.

B.Scientists around the world try to find a way to reduce air pollution. In 1979, scientists have considered a chemical, which can be mixed with gasoline to reduce the pollution caused by automobile emission called Methyl Tertiary Butyl Ether (MTBE). But recently, scientists discover that MTBE causes drinking water contaminate. Despite the warning from the scientists, government keeps continue requires MTBE must put in the gasoline.

C.There are many things to talk about this major issue, but today, I will describe the characteristic of MTBE and the reason why government despises the scientist's warning that MTBE is poisonous the underground water that is a main source supply for our drinking water.

•First of all, I will describe what is MTBE and what is its characteristic.

•Then, I will explain the reason why the government despises the scientist's warning and continue using the MTBE.
