答案：【解析】：
這道題目考查的是英語(yǔ)語(yǔ)法中的動(dòng)詞“be”的正確形式，包括肯定形式和否定形式。同時(shí)，題目還涉及到了主謂一致的原則，即主語(yǔ)和謂語(yǔ)在數(shù)和人稱上要保持一致。
1. 對(duì)于第一個(gè)對(duì)話，需要考慮到主語(yǔ)“you”和“I”以及它們的數(shù)和人稱。在英語(yǔ)中，“you”是第二人稱，其對(duì)應(yīng)的動(dòng)詞“be”的形式是“are”；“I”是第一人稱單數(shù)，其對(duì)應(yīng)的動(dòng)詞“be”的形式是“am”。在構(gòu)成否定回答時(shí)，“are”的否定形式是“aren't”，“am”的否定形式在口語(yǔ)中常用“ain't”但更標(biāo)準(zhǔn)的表達(dá)是“am not”，不過(guò)在此上下文中，更常用“I'm not”來(lái)表示。
2. 對(duì)于第二個(gè)對(duì)話，同樣要考慮到主語(yǔ)“you”和“My parents”。由于“you”是第二人稱，所以“be”的形式是“are”；“My parents”是第三人稱復(fù)數(shù)，所以“be”的形式是“are”。在肯定回答中，“are”保持不變；在構(gòu)成肯定句時(shí)，“are”直接用于主語(yǔ)后。
3. 對(duì)于第三個(gè)對(duì)話，主語(yǔ)是“Miss Li”，這是第三人稱單數(shù)，所以“be”的形式是“is”。在構(gòu)成肯定回答時(shí)，“is”保持不變。
4. 對(duì)于第四個(gè)對(duì)話，主語(yǔ)是“you and your brother”，這是第二人稱復(fù)數(shù)，所以“be”的形式是“are”。在構(gòu)成否定回答時(shí)，“are”的否定形式是“aren't”。
