3. 重点考点（就近原则实战）
离动词最近的主语是单数，动词用单数；是复数，动词用复数。1. Either Lucy or her sister likes music.（就近主语her sister单数→动词三单）2. Either the teachers or Tom goes to school early.（就近主语Tom单数→动词三单）
4. 易错提醒
❌ 不可以和both连用❌ 本身无否定含义，不要随意加not
三、neither…nor… 既不……也不……
1. 核心含义
表示两者都不选、两者都没有，完全否定含义，是both…and…的反义词。
2. 基础用法
同样连接对等成分，句子本身自带否定意义，句中不再加not！- 连接主语：Neither he nor I am late.他和我都不迟到。- 连接宾语：I like neither milk nor juice.牛奶和果汁我都不喜欢。- 连接谓语：He neither eats meat nor drinks soda.他既不吃肉也不喝汽水。
3. 重点考点（就近原则最强考点）
这是中考句型转换最爱考的点！1. Neither my parents nor my brother has a car.（就近主语my brother单数→三单）2. Neither she nor her friends are in the classroom.（就近主语friends复数→复数动词）
4. 高频句型转换
肯定句变双重否定：Both Lily and Lucy like dancing.→ Neither Lily nor Lucy likes dancing.（莉莉和露西都喜欢跳舞→莉莉和露西都不喜欢跳舞）
四、not only…but also… 不仅……而且……
1. 核心含义
表示递进关系，强调后者，前者、后者都包含，重点突出后半部分。
2. 基础用法
可连接所有对等成分，书面表达万能加分句型！- 连接主语：Not only I but also she studies hard.不仅我，她也很努力学习。- 连接宾语：He likes not only English but also math.他不仅喜欢英语，还喜欢数学。- 连接谓语：She not only sings well but also dances beautifully.她不仅唱歌好听，跳舞也很美。
3. 两大必考重难点
重难点1：严格遵循就近原则Not only the students but also the teacher helps me.（就近主语the teacher单数→动词三单）重难点2：倒装句考点（初中拔高必考）当 Not only 放句首 连接句子时，前半句倒装，后半句正常语序！正常句：He not only plays basketball but also runs fast.倒装句：Not only does he play basketball, but he also runs fast.
