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.

According to a report from Chinanews.com, Wu Ming is 【小题1】 young German born after 1995. Wu, a big fan of Chinese culture, has been learning traditional Chinese medicine (TCM) since 2016. Now he 【小题2】 (study) for his master’s degree at Henan University of Chinese Medicine and digging further into TCM.

Wu came to Central China’s Henan province in 2015, 【小题3】 a rich TCM culture can be enjoyed because it is the hometown of Zhang Zhongjing, the medical sage (医圣) of ancient China. “TCM is one of the 【小题4】 (valuable) treasures in the world,” said Wu.

Learning TCM has changed Wu’s life. He used to be addicted to electronic devices and stay up late every night, 【小题5】 (trap) in this fast paced but unhealthy daily routine. But now he lives a balanced and 【小题6】 (peace) life, practising good habits like drinking tea.

Wu also uses what he has learned to help his family. Previously, acupuncture (针灸) tools and Chinese medicine 【小题7】 (be) necessities when he went back to his home in Germany. Now, he always provides his family members 【小题8】 some advice about staying fit after he checks their skin or tongues online.

In Wu’s opinion, there’s no big 【小题9】 (different) between China and Western countries. “We are the same. Misunderstanding comes from being out of touch.” said Wu. He plans 【小题10】 (run) a traditional Chinese clinic in China or Germany after graduation, which can serve as a bridge between the two countries and publicize TCM and its culture.

Chinese vaccines（疫苗）were initially dismissed in Western and other media， partly because of a view that they were inferior【小题1】the vaccines produced by Moderna or AstraZeneca.【小题2】much evidence has been accumulating for a while that the vaccines from China work well, too.The United Arab Emirates, Pakistan and some other countries have approved the Sinopharm vaccine from China.By the end of last month,1.8 million people in the UAE【小题3】 (receive) it

The development of Chinese vaccine within a short span of time after the sudden outbreak of COVID-19【小题4】(show) the Chinese system has performed quickly according to the expectations of the international community.The development is a message for the international community 【小题5】China is marching ahead of time and the expectations of Chinese partner countries are on the rise.

China's efforts【小题6】(strengthen) the global fight against the pandemic have narrowed the space for a small group of rich countries to buy most of the vaccines.【小题7】(back)by the World Health Organization, China promised to provide tens of millions doses of COVID-19 vaccines for low and middle income countries this year.

【小题8】（personal），I would take the domestically（国内地）produced vaccines.I really think the China-produced vaccines are safe.【小题9】(live) through this global pandemic fight,I have come to a better understanding of China's 【小题10】(responsibility) attitude in the public health sector.
