Fresh flowers actually continue to grow while in a vase.So in order to keep flowers fresh, you need to consider what the flowers need to grow and stay healthy.Flowers need water, light, and food.Besides, you need to be aware of a few precautions to take.
Distilled water（蒸馏水） is the best kind of water to use for fresh flowers, because there are no chemicals in it.Change the water for your fresh flowers every day or no less than every 2 days to prevent bacteria（细菌） building up.Cut the stems under water again before putting them back in the vase, so that they will be able to draw water up easily.
Keep your fresh flowers out of direct sunlight.At night, put them in the fridge.This will prolong their life.Adding commercial flower food to good water is probably the best method of keeping flowers fresh.Some people put sugar in the water for food.That is OK, but commercial flower food has bacteria-killing ingredients, which can make the water more acidic（酸性的）.If you want a more natural food for your fresh flowers, try water that has been specially treated.That solution will also give the water acidity, sugar, and bacteria-killing ability.
Keep your fresh flowers away from fruit.Fruit gas, or ethylene, will reduce the life of your fresh flowers, making them get older faster.Ethylene is what makes fruit ripen.It is given off by dead flowers, too, so be sure to remove them.
If you follow these tips, your fresh flowers will last a long time and beautify any room in which you put them.

An old man had been working for many years for a town. His job was to clear away natural waste from the pool water in the hills, which made up the lovely river flowing through the town nearby.

The town soon became a popular attraction for tourists. Elegant swans (天鹅) floated along the clear river and the view was so beautiful   39     words.
Years passed. One evening the town    40   met. As they reviewed the budget, one man’s 41____caught sight of the salary   42   being paid to the seldom seen keeper of the river. He asked , “Who is the old man? Why do we    43  to employ him? No one in town ever 44 him. For all we know, the strange keeper of the hills isn’t doing his job.

Many years ago in a small village, an old man was hired to clear the spring (泉水) up on the mountain. He patrolled (巡逻) the spring every day, and swept away all the leaves and other things that would dirty the fresh flow of water. Soon, beautiful swans (天鹅) came to the clear spring, and the village became a popular attraction for visitors.
Years passed. One evening the town leaders held a meeting. As they looked at the salary list, one of them said, “Why do we keep this old man on year after year? I don’t think we need him or his work.” Later, the old man was asked to leave.
For several weeks, nothing changed. By early autumn, the leaves began to fall off the trees, and the spring was covered with leaves. A few days later, the water was much darker. Only a few months after the old man left, all the swans left, as did the tourists. Disease reached deeply into the village.
Quickly, the leaders held a special meeting. Realizing their mistake, they rehired the old man. Then within a few weeks, the spring began to clear up. Soon new life returned to the village.
So, my friends, do you see? No matter how small your work or your life seems to be, never overlook it. Anything we can do will make a difference.
