(答案→)helpful
解析：
【小题1】 helpful。not only…but also前后句为并列关系，应填good的相同意义词，good为积极意义的词，方框中helpful代入，亦符合句意。
【小题2】from。are chosen, 被选出，逻辑关系为“从信中被选出”，所以选择介词from。
【小题3】wasting 系动词are后应填形容词或谓语动词，由空后it可知应填谓语动词，框中适合词为waste，变现在进行时，wasting。
【小题4】enjoy。根据句意可知“你越喜欢它”。
【小题5】if。条件状语从句，由句意可知“如果不努力，就不会成功”，填if。
【小题6】received/got。此处少动词，前5题已填的词排除后还剩动词receive，代入合适，结合现在完成时态，答案填received/got。
【小题7】grow。grow up成长，长大，固定短语。
【小题8】but。前后两句为转折关系，应填转折连词but
【小题9】years。后应填名词，根据句意是20年符合，框中year代入，变复数形式years
【小题10】successful。be动词后面应当用形容词。
