核心句型：
Don't count your chickens before they hatch.
不要高兴得太早。
Don't count your chickens before they hatch 可以理解为：“在鸡蛋还未孵化的时候，不要计算有多少只鸡。因为鸡蛋一天未孵化，也就不知道能不能孵化出小鸡来，只有小鸡孵出来之后才算数。”所以这个习语也就是说：“不要太早下定论，不要高兴得太早”。因此，当美国人说"Don't count your chickens before they hatch."时，他/她要表达的意思就是:"Don't jump to conclusions too early."、"Don't draw a hasty conclusion."。
