1.Petroleum geology deals with many problems encountered by geologists and other scientists in their study of petroleum. Among them there are...........

a) a complex mixture of gaseous, liquid and solid hydrocarbons. b) the physical and chemical properties of petroleum, origin, structure. c) geographic and stratigraphic distribution, chemical and physical properties, origin, migration, accumulation, reservoir rocks, structure, methods of discovery, and a valuation of oil and gas properties.

5. Read the text and answer the questions:

People have constructed a wide variety of machines to satisfy their needs. Early people made stone axes that served as weapons and tools. The machines that were gradually developed gave people great control over their environment (physical surroundings). To operate these improved machines, people harnessed the energy of falling water and of such fuels as coal, oil, and the atom. Today, we use so many machines that the age we live in is often called the machine age.

1.What is machine? 2.Why are machines designed? 3.Is it possible to live without machines? 4.Why does our life depend on machines? 5. Why do people construct a wide variety of machines? 6. What did early people make? 7.What did people harness?

Some machines such as diesel engines or steam turbines, change energy directly into mechanical motion*. For example, the energy of steam rushing through the wheels of a turbine produces rotary motion* The mechanical energy of the turbine can be used to drive a generator* that produces electricity. Other machines simply transmit mechanical work* from one part of a device to another part. They include the six simple machines that are described below.

1. What does a machine do?, 2.What energy does a machine transform? 3.How do some machines change energy? 4. What produces rotary motion? 5.Does the mechanical energy of the turbine drive a generator? 6. How do machines transmit mechanical work? 7.What can you say about machines' ability?
