A man walked in the desert（沙漠）for two days. He ______ a sand storm during the trip. After the sand storm, he lost the sense of ______. While he was unable to hold on, he suddenly found a small old house. He pulled his ______ body into the house. There was only some wood inside. He walked to the corner hopelessly, but suddenly ______ a water pump.

Excitedly, he went to draw water（抽水）, ______ he couldn’t pump water no matter how hard he tried. He sat on the ground ______. Just at that time, he saw a small bottle with a cork（瓶塞）. There was a yellow ______ posted on the bottle, which read, “You must put the water into the pump before you can draw water! Don’t ______, before you leave, refill it with water!” He pulled the cork and found the bottle was really filled with water! He could hardly believe his ______.

At this moment, he thought, “If I only think about myself, as long as I drink the water in the bottle, I can be ______ to go out of this desert! If I do as the note told to put the only water into the pump and the water can’t come back, I will be ______ to death. Will I take the risk or not?”

Finally, he made a ______ to do what the note told him and began to draw water with his shaking hands. Sure enough, the water really ______!

After he drank enough water, he filled the bottle with water. He enveloped（封住）it with the cork and ______ his words after the note, “Believe me, it’s really ______. You should learn to pay before you get it!”
