1. aunt

1. 根据“She's my father's sister.”可知，爸爸的姐妹是姑姑，首字母是a，所以单词是aunt。
2. 根据“He's my mother's brother.”可知，妈妈的兄弟是舅舅，首字母是u，所以单词是uncle。
3. 根据“He's my uncle's son.”可知，叔叔的儿子是堂兄弟，首字母是c，所以单词是cousin。
4. 根据“She's my father's mother.”可知，爸爸的妈妈是奶奶，首字母是g，所以单词是grandmother。
5. 根据“Yaming and Yaqi are brother and...”可知，这里说的是兄妹或姐弟，以s开头，所以单词是sister。

1. is tall; has big eyes 2. handsome; funny 3. play ping-pong together 4. very beautiful; going hiking 5. my big family

1. "高个子"对应"tall"，"大眼睛"常用"has big eyes"表达，主语my sister是第三人称单数，have用has。2. "英俊"是"handsome"，"好笑"是"funny"，用and连接两个形容词作表语。3. "打乒乓球"是"play ping-pong"，"一起"是"together"，助动词do后用动词原形。4. "很漂亮"是"very beautiful"，"喜欢去徒步"是"likes going hiking"，like后接动名词。5. "我的大家庭"是"my big family"。

2. She spends a lot of time reading.
3. My mother has long black hair.
4. Her brother's favourite sport is football.
5. My grandparents are in the middle of the photo.

1. 主语We，谓语play ping-pong，时间状语every week。
2. 主语She，谓语spends，宾语a lot of time，宾补reading。
3. 主语My mother，谓语has，宾语long black hair（形容词顺序：长短+颜色）。
4. 主语Her brother's favourite sport，系动词is，表语football。
5. 主语My grandparents，系动词are，表语in the middle of the photo。

Task 5：选择正确的选项。
()1. —______ is she?
—She's my sister.
A. What B. Who C. Whose
()2. This is ______ mother,Mrs. Brown.
A. Lily and Lucy
B. Lily's and Lucy's
C. Lily and Lucy's
()3. —______ your grandfather play chess?

()4. My brother is tall,______ my sister is short.
A. and B. but C. or
()5. Teng Fei's father ______ a lot of time fishing.
A. makes B. has C. spends

1. B
2. C
3. A
4. B
5. C

1. 根据答语“She's my sister.”可知，问句是对人进行提问，用疑问词 who，what 对事物提问，whose 对所属关系提问。
2. 表达“Lily 和 Lucy 的妈妈”是两人共有的，只在最后一个名词后加's，即 Lily and Lucy's。
3. 句中有实义动词 play，一般疑问句不能直接用 be 动词，主语 your grandfather 是第三人称单数，所以用助动词 does。
4. 前半句说“我哥哥高”，后半句说“我妹妹矮”，前后是转折关系，用 but 连接，and 表示并列，or 表示选择。
5. “spend + 时间 + (in) doing sth.”是固定搭配，表示“花费时间做某事”，make 和 has 不符合此结构。
