May you + V ...
　　结构︰May＋第二、三人称主词＋动词原形＋其他
　　说明︰此句型意为"祝…"。may 此处表示祝福与愿望，多用于书面语中，口语中有时也用，但显得较庄重。本<句型>的特点是：may 不是在<主词>后面，而是摆在句子开头，使全句成倒装语序，表达出祝愿的意义。
　　May you recover soon! 愿您早日康复！
　　May you succeed in business. 祝您生意兴隆！
　　May our two parties achieve even greater successes in our business.
　　祝我们双方在生意中取得更大的成功。
　　may well + V ...
　　结构︰may well + 原形动词
　　说明︰此句型意为"理当…；大可…"。may 是<助动词>，well 是<副词>，后接原形<动词>。若将 well 置于<主词>前面，可加强<语气>。

　　你应该会发现这本书的结尾比开头好。
