Your（形容词性物主代词，修饰名词短语 best friend，注意首字母大写） 9. my（形容词性物主代词，修饰 good friends） 10. her（形容词性物主代词，修饰 friends；she 的形容词性物主代词为 her） 二、单选 1.A 2.B 3.C 4.A 5.B 6.B 7.A 8.C 9.A 10.B 三、句型转换 1. Why are you friends?（对 because 引导的原因状语提问用 Why） 2. Momo doesn't often make me laugh because he is funny.（一般现在时第三人称单数的否定句用 doesn't + 动词原形） 3. Tutu has new friends, but Duoduo is still his best friend.（but 连接两个有转折关系的简单句，注意逗号） 4. We play games together because we always have fun.（because 引导原因状语从句，说明"一起玩游戏"的原因） 5. Are you unhappy because you are not my friend now?（含 be 动词的一般疑问句将 be 动词提前；your 对应改为 my） 四、改错 1. 去掉 so（because 与 so 不能同时连用，保留 because 引导原因状语从句） 2. 去掉 Although 或 but（although / though 与 but 不能同时连用，二者只能保留其一） 3. make → makes（主语 Momo 是第三人称单数，一般现在时动词需加-s） 4. Your → You（Your 是形容词性物主代词，后面需接名词；此处需要人称代词主格 You 作主语） 5. don't → doesn't（主语 She 是第三人称单数，否定句助动词用 doesn't，后接动词原形 like） 五、连词成句 1. We are friends because we are happy together. 2. Tutu has new friends, but Duoduo is still his best friend. 3. We have different hobbies but we enjoy talking to each other. 4. Momo often makes me laugh because he is funny. 5. Friends should listen to each other. 六、补全对话 1.C 2.D 3.B 4.A 5.E 易错提醒： ① because 与 so、although / though 与 but 均不能同时出现在一个句子中，这是英语连词使用的基本规则； ② 第三人称单数（he / she / it / 单个人名）作主语时，一般现在时的动词要相应变化：make → makes, miss → misses, do → does, like → likes 等； ③ and 表并列或顺承关系，but 表转折关系，要根据上下文逻辑选择正确的连词，不可混用； ④ 形容词性物主代词（my / your / his / her / our / their）后面必须接名词，不可单独使用；人称代词主格（I / you / he / she / we / they）在句中作主语。 学科网（北京）股份有限公司 $
