3D bio-printing inside the human body could be possible thanks to a new soft robot. The device features【小题1】printing head directly mounted onto the tip of a soft robotic arm. This printing head, 【小题2】 consists of soft artificial muscles that allow it to move in three directions, works very【小题3】(similar) to conventional desktop 3D printers.

The soft robotic arm can bend and twist and can be made at any length【小题4】 (require). The printing nozzle (喷嘴) can be programmed to print per-determined shapes, or operated manually. 【小题5】 addition, a research team used a machine learning-based controller which can aid the printing process.

The team【小题6】(explain) how the device could potentially be used as an all-in-one surgical tool to perform a range of【小题7】(function). They said this could be especially important in surgery【小题8】(remove) certain cancers.

The ability to carry out such multi-functional procedures【小题9】(demonstrate) on a pig’s intestine (肠) last month and the researchers say the results show that the device is a 【小题10】(promise)candidate for the future development of an all-in-one endoscopic surgical tool. The next stage of development for the system is in vivo (活体的) testing on living animals to demonstrate its practical use.

Usually, when we talk about reading, we think of using our eyes to see letters 【小题1】 （write ) in ink on paper. 【小题2】, this is not always true. For example, blind people cannot see, but they can still read books.

The man 【小题3】 (introduce) blind people to reading was Louis Braille. Braille 【小题4】 (lose) his eyesight at the age of three as a result 【小题5】 an injury. When he was ten, he went to a school for the blind in Paris.

In 1821, a soldier visited the school and showed the students a system for passing messages at night during times of battle. His system used paper with small, raised dots 【小题6】 could be felt with the fingers. Each letter of the alphabet 【小题7】( represent) by a different pattern which consisted of twelve dots.

While the students found the soldier’s idea 【小题8】(interest), the system was too difficult to be of practical use. However, young Louis Braille took the idea and worked on it. At the age of fifteen, he created a system ---‘Braille’.

The blind can 【小题9】 (easy) recognize Braille with the fingers. Today, 【小题10】 is the most common system for them to read and write.

The latest technological advancement centering on the conversation at work, at school, and sometimes even at home, largely due 【小题1】 the emergence of chat-bots such as ChatGPT and Bard, 【小题2】 (be) Artificial Intelligence. These new conversational platforms use Artificial Intelligence (AI) to help users find instant answers, get 【小题3】 (create), and learn new things. They can chat with you and provide responses that can help you do things.

While most of the Internet agrees it’s not as good as a human at performing many tasks, the debate continues as to 【小题4】 AI has the power to replace certain jobs, or even spell the end of humankind. Of course, it brings undoubted benefits, 【小题5】 (depend) on how you use it.

【小题6】 (give) it’s often described in science fiction films and novels as a world-ending technology that results in killer robots, the current 【小题7】 (real) is less dramatic. AI is defined as a type of computer technology that is concerned with making machines work in an intelligent manner, similar to how the human mind works.

【小题8】 (actual) it means we can ‘train’ computers to learn, respond and make decisions, but it still requires the ability 【小题9】 (learn) from humans to get anywhere near good enough. While AI is a hot topic right now, the idea has existed for decades. The latest chat-bots are a form of Artificial Intelligence 【小题10】 can analyse huge amounts of data and generate responses, though they need a little reminder.
