【分析】
我们可以逐个空结合语境和语法规则来思考：
1. 第25空：主语是“Some hobbies（一些爱好）”，指物，需要用-ing形式的形容词来修饰，relax的形容词形式relaxing表示“令人放松的”，符合语境。
2. 第26空：考查固定搭配“make sb do sth”，意为“让某人做某事”，所以此处要用动词原形grow。
3. 第27空：前半句介绍David是学生，后半句说他的爱好之一是写作，前后是并列顺承关系，所以用连词and连接。
4. 第28空：后面举例“sailing and climbing”是两种活动，说明此处的activity要用复数形式activities。
5. 第29空：“writer”是可数名词单数，此处表示“一位作家”，且writer以辅音音素开头，所以用不定冠词a。
6. 第30空：考查固定搭配“encourage sb to do sth”，意为“鼓励某人做某事”，所以填动词不定式to write。
7. 第31空：时间状语是“in 2012”，是过去的时间，所以动词come要用过去式came。
8. 第32空：考查固定短语“as a result”，意为“结果”，是固定表达，所以填as。
9. 第33空：动词“brought”后面需要接宾语，he的宾格形式是him，所以填him。
10. 第34空：考查固定搭配“spend time (in) doing sth”，意为“花费时间做某事”，所以填play的动名词形式playing。
【解析】
25. 此处修饰主语“Some hobbies”（物），用relax的-ing形式形容词relaxing，表示“令人放松的”。
26. 根据固定搭配“make sb do sth”，此处填动词原形grow。
27. 前后句为并列关系，用连词and连接两个分句。
28. 结合后文举例的多个活动，activity变为复数形式activities。
29. “writer”是可数名词单数，表泛指且以辅音音素开头，用不定冠词a。
30. 根据固定搭配“encourage sb to do sth”，填动词不定式to write。
31. 由时间状语“in 2012”可知，句子为一般过去时，come的过去式是came。
32. 固定短语“as a result”意为“结果”，此处填as。
33. 动词brought后接宾语，he的宾格是him。
34. 根据固定搭配“spend time doing sth”，填play的动名词形式playing。
【答案】
25. relaxing 26. grow 27. and 28. activities 29. a 30. to write 31. came 32. as 33. him 34. playing
