Mr. White was an English teacher in Long Lake Middle School. His students loved his classes very much. It was Mr. White's 1 class before his students graduated. He decided to give the students a(n) 2 one. He put a large bottle on his desk and some big 3 around it. "There are lots of things that you have 4 in our classes. This shall be the last one. Let's 5 our class with an experiment(实验), "said Mr. White. Then he started to put the stones into the bottle.
When the bottle was full of stones, he 6 and asked, "Is there any 7 for more stones in the bottle?"
"No!"the students answered 8 without thinking.
Mr. White showed some small stones after he heard the answer. He put 9 on the big stones and shook the bottle. Soon the small stones fell into the crevices(缝隙) of big stones in the bottle. "Can we 10 things into the bottle now?"asked Mr. White.
"Can we?"the students said to themselves.
Mr. White 11 some sand and poured the sand on the top of the bottle. Then he 12 the bottle again and the sand fell into the crevices of stones. "Is the bottle full right now?"asked Mr. White. "Maybe not …"The students were not 13 about their answers this time. Mr. White smiled and 14 some water into the bottle.
Life itself seems 15 just like the bottle in Mr. White's experiment, but if you think twice and plan well, then you can add more to it.
