七、写作
A Great Invention
The wheel is one of the greatest inventions in the world. It was invented in ancient times, and it has made a great difference in our lives.
In the early days, people did not travel far from home. After the wheel was invented, humans had the power to move and carry things across long distances. Then came the wagon, the train, cars and buses.
Today, high-speed trains and airplanes help people travel faster and farther. The compass helped people explore more places, too. Every invention is a symbol of human creativity. Let us work for greater things.
【中文翻译】
轮子是世界上最伟大的发明之一。它是在古代被发明的,它给我们的生活带来了很大的改变。
在早期,人们不会离家远行。轮子发明之后,人类有了把东西运到很远地方的力量。接着出现了四轮马车、火车、汽车和公共汽车。
如今,高速列车和飞机让人们出行更快更远。指南针也帮助人们探索了更多地方。每一项发明都是人类创造力的象征。让我们为更伟大的事物而努力。
【总体分析】
①体裁:说明文(发明介绍)——按“名称与地位—由来与功能—影响与总结”展开,是典型的“主题句+事实陈述+总结”结构
②语法:一般过去时的被动语态(was invented / were invented / was written);nowadays、today 与现在完成时结合说明影响
③结构:点明发明名称与地位(开头)→ 由来、功能与后续发展(中间)→ 影响与总结(结尾)
【亮点词汇】
one of the greatest inventions(最伟大的发明之一)/ in ancient times(在古代)/ across long distances(跨越很远的距离)/ make a great difference(产生很大影响)/ a symbol of human creativity(人类创造力的象征)
【高分句型】
It was invented in ancient times.(一般过去时被动语态说明发明时间)
After the wheel was invented, humans had the power to move and carry things.(after 从句写出前后变化)
Today, high-speed trains and airplanes help people travel faster and farther.(比较级写出发明的用途)
