Activity
The third and fourth inventions have become a reality.
People nowadays can have video chats with each other via mobile phones andcomputers connected to the Internet. And many newspapers have offered their readers free digital editions. Furthermore, live chat rooms make it possible for people to communicate with reporters, statesmen and scientists.
Activity 2. read the interview and find out what inventions are mentioned.
Gunpowder, papermaking, printing, the compass, the steam engine, the telephone, the radio, virtual reality, wearable tech, the flexible battery, the 3D printer, the intelligent walking house, the wheel, the car, new energy vehicles and the time machine.
Activity
Activity 3. Choose the sentences that describe Dr Fairhurst’s opinions.
Activity
1 Inventions in Ancient China were better than those in the West.
2 A lot of today’s great inventions are tech-based.
3 Today, most inventors prefer working by themselves.

5 A time machine will definitely be invented in the future.
Activity 4
1 gunpowder, papermaking, printing and the compass
2 the steam engine, the telephone and the radio
3 the flexible battery
4 hearts and bone parts
5 an intelligent walking house
6 solar technology
7 a problem that needs a solution
8 an incredible desire to think and create
02
Using language
Activity 1. Looking at the sentences from the reading passage and answer the questions.
【Answer: Someone has asked "you” about the title ofyour book before.】
Activity
What has happened to “you” in sentence (a)
Who has used new inventions to make replacement hearts and bone parts in sentence (b)
【Answer: People have used 3D printers to makereplacement hearts and bone parts.】
Activity
【Answer: In the first group, the words in bold show the use of the passive form with the subiects, while in the second group, the words in bold show theuse of the active form with the subiects.】
What is the difference between the two groups of sentences
Why does the author choose to use the passive form instead of the active form in the reading passage

Activity 2. Rewrite the underlined parts using the present perfect passive.
Activity
Within the next 80 years, our lives may be changed beyond recognition by 3D printing. It has already affected many things in our lives, right down to the food we eat.
For instance, some restaurants in London have served 3D-printed hamburgers to customers.
3D-printed hamburgers have been served to customers in some restaurants in London.
Many things in our lives have already been affected.
Activity 2. Rewrite the underlined parts using the present perfect passive.
Activity
But perhaps the most significant success that people have achieved to date is in medicine. They have made human body parts, including a beating heart, with 3D printing technology.
And it is not just humans who are benefiting—in Brazil, people have given a new3D-printed shell to a turtle injured in a forest fire!
A new 3D-printed shell has been given to a turtle injured in a forest fire!
A new 3D-printed shell has been given to a turtle injured in a forest fire!
Activity 3. Imagine you are Dr Moore. Look at the pictures and tell the police about the damage and loss to your lab. Use the present perfect passive where appropriate.
Activity
The lock on the door has been broken.

2 What can you learn from this experiment
The egg will squeeze into the bottle.
The experiment shows us the effects of air pressure. Air pressure indeed exists, and it is very powerful.
Activity 6 Complete the boxes with the information in Activity 5. Do further research if necessary.
Activity
Introduce the aim of the experiment.
This experiment is designed toto prove whether air pressure really exists.
Describe the materials used in the experiment and explain the procedure.
I prepared a boiled egg, a glass bottle (bottleneck a bit smaller than the egg) and hot water to do this experiment.
Activity 6 Complete the boxes with the information in Activity 5. Do further research if necessary.
Activity
Procedure:
1. Remove the shell of the egg.
2. Carefully pour some hot water into the bottle.
3. Shake the bottle gently.
4. Pour out the hot water.
5. Quickly put the egg on top of the bottle.
After the experiment, I can draw the conclusion that air pressure indeed exists, and it is very powerful. It is the force of the air that pushed the egg into the bottle.
【Sample】
The experiment is designed to prove whether air pressure really exists.
At the beginning of the experiment, I prepared the materials, including a boiled egg, a glass bottle whose neck is a bit smaller than the egg, and some hot water. With all the things prepared, the experiment began.
First, I removed the shell of the egg. Then I carefully poured some hot water into the bottle, and shook the bottle gently. After a few minutes, I poured out the hot water. Just at the same time, l quickly placed the egg on top of the bottle. To my amazement, the egg squeezed into the bottle at once.
After the experiment, I can draw the conclusion that air pressure indeed exists, and it is very powerful. It is the force of the air that pushed the egg into the bottle.
