Section Ⅱ　Discovering Useful Structures 表语从句 The fact was that Wendy was a famous writer①， but no one knew where she came from and the question remained whether she was born in 1961②．What they did know was that she was loved by poor people③ because she always helped whoever was in need of money．Despite this，some people thought she was chasing fame．Why they were so narrow－minded was what Wendy couldn’t understand④， but it seemed as if she didn’t care．The most important was that she just wanted to do everything⑤ that she thought was right．She thought that was where the meaning of life lay⑥．

若表示与现在事实相反的假设，从句谓语用一般过去时（be 用were）；若表示与过去事实相反的假设，从句谓语用过去完成时；若表示与将来事实相反的假设，从句谓语用“would/could/might＋动词原形”。　 【运用练】　单句语法填空/完成句子 ①（2025•北京卷）The good news is that there is evidence we can learn to change

decades， Chinese medical teams have been transforming healthcare in Guyana， South America． Since 1993， these committed doctors have worked alongside local professionals， bringing expertise， hope and recovery to thousands． 　　Currently， the 20th medical team from Nantong， Jiangsu Province — consisting of 11 doctors — operates at Georgetown Public Hospital， providing essential services in eye care， bone care， burns， and traditional Chinese medicine． 　　Their impact is deeply personal． Longtime patient Chinian， a 65－year－old， suffered from serious eye problems and severe diabetes （糖尿病）． He expressed his gratitude to these Chinese doctors for saving his sight：“I couldn’t see before． I am so thankful to the doctors and China for this treatment．” Dr． Huang Xiaobo， who sees up to 50 patients daily， thinks Guyanese has high eye disease rates because of strong sunlight and diabetes． He feels very happy to ease people’s pain， and loves it when locals say “ni hao” and “xie xie” upon seeing the team． 　　Beyond eye care， lives are saved in critical situations． Seven－year－old Aiden suffered burns over 30% of his body． Burn specialist Dr． Gong Zhenhua used advanced Chinese techniques to get Aiden out of danger． “We’ve adopted many Chinese methods for burn patients，” noted Dr． Gong， ensuring continuity of care upon discharge． 　　Beyond direct treatment， the teams’ influence extends far． For over 30 years， they have trained local healthcare workers， fundamentally strengthening Guyana’s medical system． Georgetown Hospital CEO， Robbie Rambarran， emphasized this knowledge sharing：“The Chinese teams help us develop self－reliance — training staff， building skills and passing on what they know．” Guyana Medical Council chairman Navin Rambarran highlighted groundbreaking introductions like a new hip replacement method， helping patients recover faster． 　　Since September， the 20th team alone has treated nearly 7，000 patients， handled over 1，600 hospitalizations， performed 700 surgeries， and saved almost 100 critically ill individuals． Team leader Du Boxiang stressed their broader goal：“Building a global community of health is central． We work together to
