参考答案
1. the championship would have belonged to。 本题考查虚拟语气，表示和过去事实相反的虚拟，主句要使用would have done；短语“属于”的表达方式belong to。
2. reducing their weight by。 本题考查分词短语“减轻体重”的表达方式，应是reduce the weight；表示程度由介词by连接。同时，括号里的成分是空格前by的宾语，所以要用动名词形式。
3. greatly enriched English。“丰富”的表达方式为enrich；修饰程度用副词greatly。
4. from the perspective of an adult。分词短语“从……角度”的表达方式为from the perspective of。
5. cling/stick to their traditions。分词短语“坚持”的表达方式为cling/stick to。
