倒装和强调是高考写作的「高档句型」担当，也是语法填空的常客：Only then did I realize 这种结构，认得出是送分题，认不出是丢分题。触发倒装的关键词有限，背一张表就能全部覆盖。
部分倒装触发词对照表
| 触发情形 | 例句 |
|---|---|
| 否定词提前：never、hardly、seldom、little、not until | Never have I seen such a beautiful sunset. |
| only + 状语提前 | Only then did I realize my mistake. |
| so / neither 表「也」 | He can swim. So can I. / I don't know. Neither do I. |
| 含否定意义的介词短语提前：in no way、at no time | In no way should we give up. |
完全倒装与强调句
- 完全倒装：谓语整体提到主语前——Here comes the bus. On the hill stands a temple.
- 强调句结构：It is / was + 被强调部分 + that / who + 其余部分
- 强调人可用 who：It was Tom who broke the window.
- 强调句时态跟随原句：原句过去用 It was，现在用 It is
- not until 结构强调：It was not until midnight that he came back.
写作应用：把 I have never seen such a place 升级为 Never have I seen such a place，句式档次立刻不同。一篇作文用一到两处倒装或强调即可，多了反而做作。
易错点：强调句与主语从句的区分
判断 It is ... that 是不是强调句，用「去掉检验法」：把 It is、that 去掉后剩下的部分能还原成一个完整句子，就是强调句——It was in the park that I met her，去掉后 I met her in the park 完整成立。如果去掉后句子残缺，那就是主语从句结构，如 It is clear that he is right，去掉后不成立。另一个高频坑：So do I 与 So I do 意思不同——So do I 表示「我也是」（倒装），So I do 表示「我确实如此」（不倒装，表示认可对方所说）。考题把两者并列，先看语境是要表达「同样」还是「确认」。
