【分析】
这是一篇基础的语法填空题，解题时首先通读全文，把握整体语境是用现在进行时描述雨天周日一家人在家的日常活动，接下来逐个空判断考点：首先看括号给出的提示词，结合空格前后的词性要求、时态规则变形提示词；没有提示词的空就结合固定搭配、冠词/介词的使用规则推导合适的单词，一步步验证就能得到所有正确答案。
【解析】
1. 空格后是名词短语Sunday morning，需要用形容词修饰名词，名词rain的形容词形式为rainy，意为“下雨的”。
2. 主语是My grandparents, my parents, my cousin and I，属于复数人称，描述当下的状态，be动词用一般现在时的复数形式are。
3. 句子为现在进行时，结构是be+现在分词，空前已有be动词is，exercise的现在分词形式是exercising。
4. 固定搭配play with sth表示“玩、摆弄某物”，此处指玩球，填入介词with。
5. 空格修饰动词reading，需要用副词作状语，形容词happy的副词形式是happily，意为“开心地”。
6. 空格后是名词短语favourite show，需要形容词性物主代词修饰名词，主格he对应的形容词性物主代词是his，意为“他的”。
7. 此处表达“一位好妈妈”，good以辅音音素开头，填入不定冠词a。
8. 空前有数词twelve（十二），大于1，后面的可数名词year要变为复数形式years。
9. 固定短语be good at doing sth意为“擅长做某事”，填入介词at。
10. 语境是用电脑给笔友写邮件，不定式符号to后接动词原形，write an email表示“写邮件”，填入write。
【答案】
1. rainy 2. are 3. exercising 4. with 5. happily 6. his 7. a 8. years 9. at 10. write
