How old do you think these gas pumps are? How much do you think a liter of gas cost when these pumps were in use? How would your life be different if gasoline cost twice as much as it does now? A pair of vintage gas pumps in a desert landscape Questions 2/45 Example Answer 1 Automobiles were first mass-produced around 110 years ago. The pumps don’t look that old, but I think the pumps are probably 70 or 80 years old. Look at the photo. How old do you think these gas pumps are? Questions 3/45 Example Answer 2 I think the pumps are 50 or 60 years old. Gas pumps older than that had large glass containers on top. You pumped the gasoline into the container. Then gravity moved the gas down a hose and into your car’s gas tank. Look at the photo. How old do you think these gas pumps are? Questions 4/45 Example Answer 3 I don’t think the pumps are very old. They’ve been outside, so the weather has worn away the paint. But the design is fairly modern, so they might be 30 or 40 years old. Look at the photo. How old do you think these gas pumps are? Questions 5/45 How would your life be different if gasoline cost twice as much as it does now? Example Answer 1 My life would be very different because my family has a car. My parents use it to go to work, to go shopping, and to go out at night. If gas cost twice as much, we would use the car less, and only for necessary trips. In addition, the price of many things would also go up, so we might not have enough money to buy all the things we buy now. Questions 6/45 How would your life be different if gasoline cost twice as much as it does now? Example Answer 2 My life would not be very different because I usually walk or ride a bicycle. I also buy most of my food from local farmers, and higher gas prices wouldn’t affect them much. I don’t buy a lot of clothing, electronics, or other goods, so higher prices on those things wouldn’t affect me very much. Questions 7/45 Look at the photos and the graphic and read the captions. Then discuss the questions. Based on the information in the graphic, what is the majority of oil used for? What are some of the things oil is used for besides transportation? What alternatives to oil are being used in China? After oil 8/45 In our daily lives, we use oil for a wide variety of things—from fuel for our cars to medicine to sports shoes to plastic bags and water bottles. Many people believe that our consumption of oil is reaching its peak. Oil will never be as cheap and common as it is now. This graphic shows how a typical barrel of oil is used. (1 barrel = 42 gallons or 159 liters) After oil 9/45 Some scientists say we must shift to alternative forms of energy to prepare for the time when our supply of oil will be depleted. Finding substitutes for oil will be a priority for scientists and countries in the coming years. After oil 10/45
