A am B is C are D be 答案：A 解析：either.or.连接并列主语时，谓语动词与靠近的主语保持一致，此处靠近谓语的主语是I,对 应的be动词用am。 考法二：either...or.连接主语时的主谓一致及否定形式转换 核心：结合either..or.…连接主语时的就近原则，以及与neither.nor.的否定转换进行综合考查 真题1（语法填空）： Either my friends or my brother一(be)going to help me with the搬家。 答案：is 3 初三下册教科版（五四制） 【语法专版】 Unit9知识点全解 解析：either.or.连接并列主语时，谓语动词遵循就近原则，靠近谓语的主语是ny brother(单数)， 故用is。 真题2（单选题)： He is a teacher_a doctor.He is a driver A.either;or B.neither;nor C.both;and D.not only;but also 答案：B 解析：由后句“他是一名司机”可知前句表否定“既不是老师也不是医生”，neither..nor.表示“既 不…也不…”，符合语境：A项表选择，C、D项表肯定并列，均不符合。 考法三：either..or.的综合应用与易错点辨析 核心：结合连接成分判断主谓一致，掌握否定转换及倒装规则，识别省略用法错误 真题1（单项选择)： Either my friends or my teacher-going to help me with the project. A.is B.are C.am D.be 答案：A 解析：either.or.连接主语时遵循就近原则，靠近谓语的主语“my teacher”为第三人称单数，因 此be动词用is。 真题2（语法填空）： You can either(take)the train or the bus to the station. 答案：take 解析：either.or.连接并列谓语时，第二个动词可省略与第一个重复的部分，但此处or后为名词短 语“the bus'”,并非动词，因此第一个take不可省略，需用动词原形与can搭配。 真题演练 演练一：单项选择试题（共10题) 1.Either you or Iresponsible for the mistake.
