任务一：
★预习课文
Believe it or not, technology has left a mark on our lives. In the past, you had to go out to get food, and now you can order online and get it delivered to your doorstep. In the beginning, people were doubtful about spending money on a product without seeing it face to face, but now more than 90% of them prefer shopping.
Every person is surrounded by technology in a way. A typical example is Internet of Things (IoT). It introduces the features of smart homes where you can turn lights on and off through your smart phone. Similarly, it allows you to lock the doors of your entire house by making a few clicks. Hence, besides making lives easier, it is promoting a safe environment at home.
It is amazing to think that we managed to go from the big landline phones to small wireless computers in only a few decades. Now, you can check the web, make calls, watch videos, and even work on your smart phone.Technological innovations have truly changed our lives in so many ways.
They are benefiting almost every industry while changing the way things work. And, of course, innovation has not stopped. You will surely welcome bigger and better innovations sooner or later. After all, the future is all about robots, smart homes and self-driving cars.

任务二：
★阅读议论文文章
What is the most valuable thing in life? Different people hold different opinions. Some
value money most, while some others treasure beauty. However, | do believe in the saying,
"Friendship is one of life's greatest treasures". So, | cherish friends most.
People always say that a life without a friend is a life without a sun. My opinion coincides
with this idea. Man is a social animal. We find fulillment in association with others, especially
those who share common interests with us. Besides, all of us, at certain moments of our lives,
need to take advice and receive help from other people. A good friend is like a mirror. It
shows you not only your shining points but also your shortcomings so as to help you become
a better person.
Of course, another saying goes that a friend in need is a friend indeed. Those who share
only the happy moments are not the friends that | have in my mind, and those who are willing
to share both happiness and hardship are true friends we should treasure.

阅读文章，完成思维导图
一、教材分析
本课教学内容选自教材Unit 7读写部分。文章是一篇科技议论文，按照总分总结构，开篇提出科技已在人们的生活中留下烙印这一观点，然后通过对比以前和现在人们生活的变化，举例验证观点，最终归纳总结并表达作者对科技创新给人们生活带来变化的积极态度。要求学生根据阅读材料和所给观点，完成一封倡议书，倡导人们积极、正面面对和利用科技进步，内容融合思政元素。
