三、完形填空
A teacher was giving a talk to his students on stress (压力) management. He raised a glass of water and asked them, “How 　11.　 do you think this glass of water is ”
The students began to think and 　12.　. Their answers are different, from 20. g to 50.0. g.
“It does not matter on the real 　13.　. It depends on how long you hold it. If I hold it for a 　14.　, it is OK. If I hold it for an hour, I will have an ache in my right arm. If I hold it for a day, you will have to call a 　15.　. It is the exact same weight, but the longer I hold it, the heavier it becomes. What we have to do is to put the glass down, 　16.　 for a while before holding it up again.”
“If we carry our burdens (负担) 　17.　, sooner or later, we will not be able to carry on. The burden will become increasingly heavier. We have to 　18.　 the burden every now and then, so that we can be refreshed and are able to carry on.”
So 　19.　 you return home from work tonight, put the burden of work down. Don't carry it back home. You can pick it up tomorrow.
Whatever burdens you have, let them down for a moment if you can. And learn to 　20.　 ourselves.
Life is short but amazing. Enjoy it!
