People come into your life for a reason, a season, or a lifetime. When you figure out one it is, you will know what to do for each person.
When someone comes into your life for a reason, it seems that they (especial) come to meet a need you have expressed. They come to help you through a difficulty, to provide you advice and support. Then, this person will say or do something (bring) the relationship to an end. What we must realize (be) that our need has been met, and their work is done.
When people come into your life for a season, they bring you a (peace) experience or make you laugh. They may teach you something you have never known. (give) you lots of joy is their mission. You may enjoy (your) together. It is real! However, they come to your life only for a season.
Lifetime relationships teach you lifetime lessons. Your job is to accept lessons, love the person, and put what you have learned to use in other (area) of your life.
实验目的：在盐水中漂浮是否比在淡水中容易。
实验器材：三杯温水, 量杯, 广口瓶, 盐, 勺子, 生土豆。
实验步骤：将一杯半温水倒入广口瓶; 加入三分之一杯盐; 搅拌至盐完全融化; 再加一杯半水, 把这些水慢慢从勺子背面倒入广口瓶使两种液体不混和在一起; 轻轻将土豆放入瓶中, 不要使它掉落到瓶中。
实验结果：土豆会沉入水中——但只会沉入一半。
实验结论：在盐水中漂浮比在淡水中容易。
