四、完形填空。
(连云港期中)During the Warring States Period, there was a state called Wei. There were many long dikes(堤坝) in Wei. They 1 people from floods.
Bai Gui, an official of Wei, worked on flood control. He went to 2 those dikes quite often. One day, Bai Gui went to the dikes as usual. He found a small hole on the dike. It was only about the 3 of a grain of rice. However, Bai Gui said to workers at once, “This small hole must be 4 as soon as possible.” A worker looked at the hole carefully, and he felt so 5 that he wondered what big problem such a small hole could cause.
Bai Gui explained to the workers 6 the ants could destroy the dikes sooner or later. He said, “7 we don’t fix the hole in time, the ants will keep digging and make it bigger, and there will be more and more holes. The dikes will be 8 by them some day.” Bai Gui also warned 9 seriously, “To keep our dikes from danger, we need to 10 small ant holes. If we leave them alone, they may cause awful floods, destroying our fields and homes. We should be careful and deal with small holes 11 to avoid trouble! Or it will be too 12 to regret our inaction!”
Thanks to Bai Gui’s hard work, the dikes in Wei were always very strong. They were 13 washed away by the floods and the people could live in peace.
