Facial surgery (手术) is a serious business, especially on children 【小题1】 are not yet fully grown but Melbourne researchers are developing a technique that could change the face of children’s surgery.

This new 【小题2】 (develop) will allow doctors to work out a child’s normal face shape at different ages to predict (预测) future growth.

Researchers at the Murdoch Children’s Research Institute (MCRI) could soon replace the ruler currently 【小题3】 (use) to track changes in a child’s head and face with 3D images. By 【小题4】 (improve) the ability to predict normal growth and future changes in a child’s face, doctors will be able to【小题5】 (well) complete their surgery than before.

MCRI’s Mr Harold Matthews said current 【小题6】 (method), including using patients’ photographs and X-rays were slow. Together 【小题7】 researchers in Belgium, Mr Matthews is pioneering a new tool that provides averages (平均值) for normal growth of the face throughout childhood.

The project intends 【小题8】 (take) some of the guesswork out of surgery. For example, in children with Pierre Robin Sequence, a serious condition which means they are born with an underdeveloped jaw(下颚), some doctors choose to fix it early while others wait to see if the child’s face will 【小题9】 (natural) correct itself as it grows. Without this new technology, 【小题10】 is difficult to know which method is better for each child.

President Xi Jinping has called for efforts to advance the construction of the Sichuan- Tibet Railway project with high quality,【小题1】(say) that it has great relevance to promoting socioeconomic development in the western region. Xi, who is also general secretary of the Communist Party,【小题2】(make) the remark in an instruction on the construction of the railway's Ya’an-Nyingchi section,【小题3】 started on Sunday. He emphasized that this project is a significant step in carrying out the Party's strategy of governing the Tibet autonomous region. It is【小题4】(vital) important for the country to safeguard national unity, and consolidate (巩固)stability in border areas. He also required the governments of Tibet and Sichuan province to strengthen cooperation in the process 【小题5】(ensure) high-quality construction in a scientific and environmentally friendly manner.

Construction of the line is taking place in three stages. The Chengdu-Ya'an section became operational in 2018, and the Lhasa-Nyingchi section is【小题6】 construction. The middle section will be one of the world's most challenging【小题7】(project) because it climbs from 600 meters above sea level to nearly 4,500 meters. Once it【小题8】 (complete), the railway will cut the travel time between Chengdu and Lhasa. The project will be【小题9】 (benefit) to millions of people along the line just【小题10】 it will promote travel between Tibet and the rest of the country.

Technology is constantly advancing. 【小题1】 we imagined it years ago cannot keep up with its pace of development. In the past, autonomous vehicles were just a part of movies, 【小题2】 these technologies are now successfully coming into being. An autonomous car, also 【小题3】(know) as a self-driving car, can perform all functions related to everyday driving and parking. It is a technology that senses the environment and, upon entering the destination, 【小题4】(find) its way without human intervention.
