(注意:does he like 是部分倒装,即把助动词does提前) 倒装规则: 确定原句的时态和谓语动词。 根据时态和主语,在 not only 部分加上相应的助动词 (do, does, did, have, has, will, can 等),并将助动词提到主语前面,主要动词变回原形。 but also 部分语序不变。 例句: 正常: She is not only a teacher but also a writer. 倒装: Not only is she a teacher, but she is also a writer. 正常: I not only heard it but also saw it. 倒装: Not only did I hear it, but I also saw it. 对七年级学生的建议: 倒装句是一个拔高内容。首先要掌握好正常语序的用法。在学有余力的情况下,尝试理解和模仿倒装句,这会让你的英语表达更出色。 五、 总结与记忆口诀 结构对称是核心: not only A but also B,A和B的结构要一样(都是名词,或都是动词等)。 主谓就近要记清: 连接主语时,动词单复数由B(即but also后面的主语)决定。 倒装句首Not only: 如果把Not only提到句首,后面句子要倒装(助动词提前)。 口诀: “Not only, but also, 并列成分两边靠。 主语连接谓就近, 句首倒装要记牢。” 1._____ the students _____ their English teacher likes watching basketbal ... ...
