【正确答案】：41、showed/shown

44、morally
45、social
46、controlling
47、ability
48、affects
49、performance

【题目解析】：41、【showed/shown】has后面加动词的过去分词，show的过去分词有两种，分别是shown和showed。
42、【greater】根据后面“better（更好的）”、“fewer（更少的）”，可推断这个空填比较级，“great”的比较级是“greater”。
43、【playmates】该空在形容词“fun”后面，则填入名词，根据意思判断应为复数形式，则填入“playmates（玩伴）”。
44、【morally】空格前面是“and”，则词性一一对应，“emotionally（感情上）”是副词，则填入副词“morally（道德上）”。
45、【social】该空修饰名词“skills（技能）”，填入形容词“social（社交的）”。
46、【controlling】practice 后面加动词的ing形式，也可根据句中的“and”来判断单词的形式，“and”后面接的是“responding”，则对应填入“controlling”。
47、【ability】“their”后面缺一个名词，“able”的名词形式为“ability”，这里的能力指的就是后面接的“to think through and negotiate different situations in their relationships（去思考和协商他们关系中的不同情况）”作为一个整体，则填入单数形式“ability”。
48、【affects】空格前后都是名词，该空需填入动词，根据文章的时态，应该使用一般时态，主语“Having friends”是单数，则谓语动词也用单数形式，则填入“affects”。
49、【performance】该空应该填入名词，且原文并没有指很多种表现的意思，所以使用单数形式，则填入“performance”。
50、【necessity】“a”是冠词，后面接名词，则填入“necessity”。
