It is not an unfamiliar word. It is heard, said, discussed day after day. It is close to everyone’s daily life. You turn on a lamp and it is energy that gives you light. You turn on a TV and it is energy that gives you pictures and sound. You ride a motorcycle and it is energy that gives you movement. You cook your meals and it is energy that gives you heat to boil rice. The problem is that the demand for energy is rising and that the price of energy is getting higher and higher. The supply of energy on earth is limited. It cannot provide us forever. The shortage of energy in the future is inevitable. Therefore, saving energy is a must if we want to continue to live in a safe and sound world. * Notice: familiar: thân thuộc demand: nhu cầu inevitable: chắc chắn xảy ra Statements True False 1. Many people aren’t interested in the problems of energy. 2. The word “energy” is familiar and close to everyone’s daily life. 3. Energy is heard, said, discussed day after day. 4. We can’t watch TV without energy. 5. The supply of energy on earth is unlimited. It can provide us forever. 6. If we want to continue to live in a safe and sound world, we have to save energy
