23、ainer in our city to you.He is my uncle，a master of Tai Chi which is always invited to teach others all over the country.答案与解析本文作者介绍了学习太极的好处，并且向朋友推荐自己的叔叔来做朋友的太极教练。1第一句中的them改为it。考查代词。指代Tai Chi，用it，所以them改为it。2第二句中的hand前加上冠词a。考查固定用法。give sb.a hand帮助某人，是固定用法，所以在hand前加上冠词a。3第三句中的wide改为widely。考查副词。修饰动词a

24、dmitted，用副词，所以wide改为widely。4第四句中的Knowing改为Known。考查固定用法。be known for因而众所周知，是固定用法，所以Knowing改为Known。5第四句中的provided改为provides。考查时态。表示一个客观的事实，用一般现在时，且主语Tai Chi是第三人称单数，所以谓语动词也用单数，故provided改为provides。6第五句中的Because改为Although/Though/While。考查连词。句意：尽管它很难学，但是它对你的健康和大脑有益。表示“尽管”，所以Because改为Although/Though/While。7

25、第五句中的for改为to。考查固定短语。be beneficial to有益于，是固定短语，所以for改为to。8第六句中的about删去。考查介词。concerning为介词，意为“关于”，相当于about，所以删去about。9第六句中的what改为that。考查宾语从句。句意：我自豪地告诉你我有能力推荐我们城市中最好的学校和最好的教练给你。I have the ability to recommend the best school and best trainer in our city to you作tell的宾语，引导词在从句中不作任何成分，也没有什么实际意义，所以what改为th

26、at。10第七句中的which改为who。分析句子可知，先行词是my uncle，指人，而且在从句中作主语，所以which改为who。.实战演练假定你校正在开展“创建绿色校园”活动。请你以此为主题用英语写一篇演讲稿，内容包括：1创建绿色校园的意义；2列举一些校园浪费的现象；3发出倡议。注意：1.可适当增加细节，以使行文连贯；2词数100左右，开头和结尾已给出，不计入总词数。Dear friends，As is known to all，our school has launched a program in order to build a green campus.Right now was
