A. Read silently the introduction of a lecture on technology while listening to the recording.
Technology has changed the world and our individual lives in virtually countless ways. Despite this, it is still common for people to bemoan these achievements. Additionally, news outlets like to speculate about the danger of robotics. With all of this negativity, it is easy to forget about the perks associated with technology, including the fact that Lifehack and the entire Internet wouldn’t exist without it. Therefore, it’s a good idea to take a few moments to recognize a few pieces of technology that are dedicated solely to making life easier and more secure. Without these advancements, everything from deadly illnesses to identity theft would be much more prevalent.

In black, of course, and ultrathin, the watch is $19.95 from Lorus Products at department stores.

● 9. Take a close look at the picture below. Think about it for one minute. Then make a two-minute oral presentation to tell the class what you think of the picture.

The following expressions may help your presentation:
1. the human brain 人脑
2. desktop telephone 台式电话
3. the shrinking of the human brain 人脑萎缩
4. mental capacity 智能
* Suggested Presentation:
As we can see from the picture, the human brain is getting smaller and smaller with the development of the telephone. The picture conveys a significant impact the development of the telephone has on the size of the human brain. The smarter the telephone gets, the smaller the size of the human brain will become.
In the picture, the first one is called desktop telephone, which sits with a big human brain. After that, we began to have cellular or mobile phones. Each sits with a human brain. But the problem is that the human brain gets smaller and smaller. The smallest one appears with the current cellphone.
From the association of the development of the telephone with the size of the shrinking of the human brain in the picture, we can see that the human brain gets smaller as the cellphone gets smarter, which means that we are losing our mental capacity as we’re increasing our dependence on the cellphone. Is it true?
● 10. Have a discussion on the topic below.
The following expressions may help your discussion:

* Try This Discussion:
Student A: They say 4G changes life, and 5G will change society. If they’re right, I can see the future of 5G. 5G means the future of faster Internet connectivity and communication.
Student B: That’s really something. We once said that we could not talk about China without talking about the Great Wall. Now we can say that we cannot talk about China without talking about 5G. I’m really proud of the technical advances we Chinese have made.
Student C: To my knowledge, the 5G technology will provide the fastest Internet ever, with speed up to 10 times faster than the current wireless networks. It’s unbelievable. It’s hard for me to imagine its potential. No wonder they say 5G will change society. With such smartphones, we are transforming into a smart city.
Student D: Everything can be double-edged, as we tend to say everything has both advantages and disadvantages. So I would say the future of 5G will come to us with unavoidable disadvantages. But just because 5G can have disadvantages does not mean we’re not going to embrace (拥抱) it. I’m sure human beings are smart enough to overcome them.
