【分析】
本题为英语语法填空题，需结合语境、词性、时态、固定搭配等知识解题。每空思考逻辑：36题修饰名词daughter需用形容词性物主代词；37题根据现在进行时结构填动词现在分词；38题主语为第三人称单数，一般现在时用动词三单；39题表泛指“一名”用不定冠词；40题collect后接名词，需用paint的复数名词；41题是固定搭配hope to do；42题修饰名词dress用形容词；43题是固定短语side by side；44题前后为因果关系用连词；45题修饰动词用副词。
【解析】
36. 修饰名词daughter，需用形容词性物主代词，they的形容词性物主代词是their，故填their。
37. 由is及语境可知是现在进行时，结构为“be+现在分词”，sit的现在分词是sitting，故填sitting。
38. 主语是he，表经常性动作用一般现在时，work的第三人称单数形式是works，故填works。
39. 表示“一名中学生”，middle以辅音音素开头，可数名词单数前用不定冠词a，故填a。
40. collect后接名词作宾语，paint的名词painting表泛指用复数paintings，故填paintings。
41. 固定搭配hope to do sth.（希望做某事），故填to become。
42. 修饰名词dress需用形容词，colour的形容词是colourful，故填colourful。
43. 固定短语side by side（并排），故填by。
44. 前句“她很小”和后句“不上学”是因果关系，用so，故填so。
45. 修饰动词climbing需用副词，slow的副词是slowly，故填slowly。
【答案】
36.their 37.sitting 38.works 39.a 40.paintings 41.to become 42.colourful 43.by 44.so 45.slowly
