The expository essay is about 450 words

There are a lot of loofahs in our community, and I also have loofahs on my balcony, and I climb up the wall until I reach the window on the fourth floor.

The leaves of the loofah are tender green, and after a few days the leaves grow and turn dark green. The leaves of the loofah are like palms, the big "palms" are next to the small "palms", and the small "palms" are next to the large "palms", just like the big hands holding the small hands. The leaves are overlapped, leaving no gaps.

A gust of wind blows, and the leaves of a wall flutter with the wind, rippling and rippling, which is very beautiful.

Every June and July, the loofah will bloom small yellow flowers. Every time a small flower blooms, it attracts many bees and butterflies, and the industrious bees "buzz" and are busy collecting nectar, and the butterflies flutter and loom in the leaves. After the loofah flower withers, a loofah will bear at the bottom of the flower, and the new loofah will be the size of a finger, and then it will grow thicker and thicker, and the longer and longer, and finally, the loofah will hang down to the ground like a green stick.

As long as you pick the loofah, stir-fry and eat, it is delicious.

Before, I only knew that this plant was called a loofah, but I didn't know how it could climb. Today, I noticed that the filaments of the original loofah can wrap around obstacles to climb, and where the petioles grow on the stem, a branch-like filament sticks out from the opposite side, and each filament is like a snail's antennae. The filaments, like the new leaves, are also tender green.

This is the tool for loofah climbing.

When the filaments of the loofah hit an obstacle, the filaments bent and wound around one by one. The filament, which had been straight, is now curved, pulling the young stem of the loofah so that it clings tightly to the obstacle. That's how the loofah climbs up one foot at a time.

Don't underestimate those filaments, which are so strong that they wrap around obstacles, and if your fingers don't take a little effort, you won't want to pull off one of the stalks of the loofah.

Another addition to my family's electrical appliances is my family's newly purchased Angel brand water dispenser.

This water dispenser is divided into two parts, the upper part is connected to water, and the lower part is a disinfection cabinet. The body is milky white, the body is rectangular, and it carries a water purifier on it, which is oval.

The role of this water dispenser is great, the most important thing is to help us boil water, and the disinfection cabinet can disinfect the container that receives the water. A water purifier is to consider water as clean water, which is both clean and hygienic. For example:

If parents are too busy and don't have time to boil water, then the water dispenser can help you boil the water, you just need to let the water dispenser start boiling water, and then you can wait, the water is boiling, and you can drink it with confidence.

According to my mother, the method of using it is very simple: first remove the upper cover of the water purifier, put tap water in it, and it will discharge clean water through the filter. Then press a red button on the back of the fuselage, the water dispenser will start working, about three minutes or so, the water will boil, at this time, there is a small dot on the upper half of the fuselage, its color will turn from red to yellow, proving that the water is boiling, and then take the cup, pull the switch down with your hand, and the water will come out, at this time, you can drink water.

Although my water dispenser is not as good as a fully automatic water dispenser, our family will never forget its credit.
