【PTE干货】PTE 高频summarize spoken test精析 (十:Light bulb)

Light bulb


主要内容介绍:这段上课的录音是关于一直亮着的灯泡和它所能消耗的能源


笔果还原听力原文:

This is a 40 watt light bulb. If you leave it on all the time, it uses a kilowatt hours of power every day. And it is possible to use that to measure all forms of power consumption using this unit of light bulb. I started measuring everything around my house, around my office and I found some surprising things. First I plugged in a phone charger. It didn’t even register on this calorimeter. It used 100 of light bulbs worth of power. I don’t think the phone charger is gonna be our number 1 form of energy consumption. Just taking one hot bath every day uses the same energy, same power of 5 light bulbs all the time nonstop. And I have been using steadily about 40 light bulbs worth of gas for heating, making hot air, hot water and that surprised me. Transport is one of the biggest forms of energy consumption. It uses about a third of our energy. If you drive an average car 50 km a day, that corresponds to 40 light bulbs on all the time.
