According to a recent report, many people like to stay on the couch and watch TV. In this way, more and more “couch potatoes” are being born.See what technology does.

Its part of life, and at the difficult times, just stopping is not right, we need to ask for help.When I have a problem, I never go to a single person for help. In fact, Im lucky enough to have a strong support group.First, I have a good relationship with my parents. When Im faced with difficulties, my parents are the first people I turn to.

Having problems is nothing to be afraid of. When you need to, go to ask for help, because the help of another can often get you through you darkest time!An Old Tree Tells You .Dear human beings,I hesitated a lot before writing this letter. All I want to do is to ask you to have a look at your life. But Im not sure whether or not youll pay attention to me.Im a pretty old tree: Im 80 years old. So Ive seen much of the world. Weve lived on the Earth for thousands of years. Each day we release oxygen and remove harmful gas so that you have pure air; we cool the air so that you dont have to run your air conditioners all the time; we help prevent the Earths soil from being washed away; and above all, we give all kinds of fruits, nuts, beans as well as wood to you.But we are in great danger now because of you. You are, in fact, destroying us at a terrible speed. You are burning and cutting down millions of us each year. For every tree being planted today, 30 trees are being cut down. What would you do if all of us died? Perhaps you would die, too. Without us, you wouldnt get the ingredients for some of your important medicines, you wouldnt have enough materials for buildings, furniture, paper products and your cities would look ugly. Moreover, air pollution and noise pollution would become more and more serious, and your life would turn nasty .Well, the list could go on forever, but I think I should stop. The best thing for you to do now is to stop your bad practice. Please stop destroying us and start protecting the environment, because we are the best fighters against pollution and we are your best friends!I wish all the best for you, and good luck!Your friend,An old treeElectricity Electricity is a pretty powerful force and it is used in many parts of peoples daily life.Types of ElectricityThere are two main types of electricity: direct current and alternating current.
