动词来“帮助”它构成倒装句。如:

(√)Only after the war did he learn the sad news.
如果句子为主从复合句，则主句倒装，从句 不倒装。例如：

态倒装至主语之前。如果句子的谓语没有助 动词或情态动词，则需添加助动词do, does
或did，并将其置于主语之前。 句型

• I usually have a lot of meetings to attend.
• She is a nice person to work with.
• I have many letters to write. （to write many letters）我有许 多信要写。

nothing, anything 等不定代 词时。
• Do you have anything to say?
