阅读下面短文，并从每题所给的四个选项中选出最佳答案。
The teacher walked into the classroom with a smile on her face. She asked all the students to close their books and pay attention. Then she began to tell them about an important lesson in life. She held up a glass of water and asked, "How heavy do you think this glass of water is?"
The answers ranged from 20g to 500g. She replied, "It doesn't matter how heavy it is; what matters is how long you hold it. If I hold it for a minute, it's not a problem. If I hold it for an hour, my arm will ache. If I hold it for a day, I'll have to call an ambulance."
This simple example illustrates that if we carry our burdens all the time, sooner or later, they will become too heavy to bear. It's important to put down your burdens at times and rest so that you don't wear yourself out.
