hearts and bone parts in sentence (b)
Grammar: Present perfect passive
Compare them with the following sentences and answer the questions.
c. I guess someone has asked you about the title of
your book before.
d. People have used new inventions like 3D printers to
make replacement hearts and bone parts.

2. 强调动作的承受者，而不强调动作的执行者。例如：
All these products have been tested.
（这些产品都经过测试了。）
Grammar: Present perfect passive
3. 动作的执行者很模糊。例如：
The letter has been opened.
（这封信被人拆开了。）
4. 有时为了礼貌的需要，避免说出动作的执行者。例如：
They have been told many times not to make noises.
（已经有人多次跟他们说别那么大声了。）

Rewrite the underlined parts using the present perfect passive.
Grammar: Present perfect passive
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. 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 new 3D-printed shell to a turtle injured in a forest fire!
