Youth comes only once in a lifetime, therefore, it is important that we should not waste those years in idleness and bad living.
This is also the time when our memories are best.We are able to learn more during this time than when we become older. During our younger years, we have the enthusiasm to set high goals for ourselves. We also try to overcome obstacles which are placed in our way.
If we realize how precious youth is, we will be fulfilled when we are young as well as when we are older. If we waste our youth, we will spend the rest of our lives wishing we could be young again.
Some of us always spend Sundays aimlessly. We can seldom derive profits from the valuable hours (time) of Sundays. This is indeed a great pity. Though Sundays are set aside as a day for rest, we must make good use of them.
We know that our school lessons are usually not sufficient. We should often utilize Sundays to read reference books. In this way we will increase our knowledge. Besides, we must be engaged in sports or outing so as to strengthen our bodies.
Cactuses are used to living in desert. The whole body of a cactus is green. The stalk is oval and there are thorns all over its body. Actually the thorns in their bodies are their leaves. The leaves are like this only because they can stop the water in their bodies from evaporating into the hot and dry air. The cactuses have long roots and they take their roots deep into the earth so that they can get the water from deeper,soil.
Their flowers are always small and white.Although they are ignored in the desert, they never give up coming ont and alwaysdecorate the desert silently.
The summer vacation had come round again. I was happy that I could forget about school at least for a while. Lest I fool around all through this summer vacation, I made a plan as to how to spend it. First, I thought I should go over all those things my teachers taught in the previous term so that I could have a better understanding of them. Then I thought I should take up some forms of exercise, such as walking, running rowing, to keep me physically strong. It stood to reason that with such a good plan I should make the best of my vacation time. I did, because I lived up to what I had planned.
