The electric light bulb is one of them. In the past, people could only read or work during the daytime because there was no good way to light up the night. This was a big problem. Then Thomas Edison came up with a brilliant idea. He tried many times and never gave up. Finally, in 1879, he invented the practical light bulb. It is made of glass and is used to give us light. Thanks to the light bulb, people can work and study at night. It has not only made our rooms brighter, but also brought great changes to the whole world. For example, factories can run longer and hospitals can help patients at night. Great ideas like this make our life better and encourage us to think more creatively. 【范文亮点】运用本单元短语 come up with / solve the problem / thanks to / be used to / bring great changes to / all over the world；使用 then / finally / thanks to / not only ... but also / for example 等连接词保证连贯；一般过去时叙事、一般现在时评价，人称第三人称，符合中考评分标准一、二、三档要求。 学科网（北京）股份有限公司 $
