1. Never look a gift horse in the mouth.
别挑剔人家送你的礼物。

2. Yesterday is a history, tomorrow is a mystery, but today is a gift, that is why it is called Present.
（——by《功夫熊猫》Mr. wugui）

3. Experience is a precious gift, only given a man when his hair is gone.
经验是一件珍贵礼品，只献给头发脱落的人。

4. Gift horse 特洛伊木马

5. Beware of Greeks bearing gifts。当年希腊人给特洛伊人遗下木马(the Trojan horse),一夜之间反而攻取了特洛伊;所以,这成语是说‘提防献殷勤的敌人’。

6. Don't / Never look a gift horse in the mouth.
不要对别人送给的礼品过于挑剔”（Be grateful for something that is given to you, without asking questions about it or finding fault with it. 其中的" horse "，有人认为它指的是特洛伊木马，也有人认为这里的" horse "指的是人们购买马匹时通过查看马的牙齿来确定马的年龄（或健康状况）的做法。如果你了解特洛伊战争的话，就不会将这里的horse和特洛伊木马联系起来。如果特洛伊人真的让特洛伊木马张开嘴瞧一瞧的话，他们会大吃一惊，或许不会中计而落得一个被征服的下场了。）
