"only"的倒装句变回正常语序的方法如下：

将状语移动到句末：

将"only"后面的状语（如副词、介词短语或从句）移动到句子的末尾。

将谓语的一部分放回主语之后：

将原句中的谓语动词的一部分（如助动词、情态动词等）放回到主语之后。

示例

倒装句：Only then did he realize his mistake.

正常语序：He realized his mistake only then.

倒装句：Only by shouting was he able to make himself heard.

正常语序：He was able to make himself heard only by shouting.

倒装句：Only in this way can we learn English well.

正常语序：We can learn English well only in this way.

注意事项

当"only"后面跟的是副词、介词短语或从句等状语时，句子需要倒装。

如果"only"后面直接跟的是主语，则通常不需要倒装。

通过以上步骤，你可以将"only"的倒装句轻松变回正常语序。
