Completethemindmapwithinformationfromthepassage.Post-readingActivity-4ThinkandShare.LanguagePoints1.Inaddition,importantadvanceshavebeenmadeinmedicineandenvironmentalsciencethankstoincreasingcomputerpower.[句式分析]本句语法点为“现在完成时的被动语态”，结构是have/has+been+done.表示过去发生的事对现在产生的影响，且本句主语是importantadvance，与谓语make之间是被动关系，需要用被动语态。[尝试翻译]此外，由于计算机功能增强，医学和环境科学领域也取得了重大进步。LanguagePoints2.Butwhatremainsimportant

isthatwehaveanincredibledesiretothinkandcreate,andthere’stherealspiritofinvention.[句式分析]本句由两个从句引导，即主语从句和表语从句。Whatremainsimportant是主语从句，作整个句子的主语，译为“（一直都是）重要的是”。...isthat...引导了表语从句，其中引导词that不可以省略。[尝试翻译]但重要的是，我们要一直对思考和创造有着非一般的的追求，这才是发明创造的真正精神。Homework-Reviewnewwordsa
