Our government is trying hard to build an energy-saving society. It is somebody’s duty to work hard and reach this goal. Besides, not everybody has realized the important of it. Take our school for example. Sometime we can see that lights and computers are still on after class. Some students even forget to turn on the tap after using it and have water run all the time. Our papers are printed on only one side, which causing much waste. It’s time we did something to avoid this kind of waste. Firstly, make sure that all the light and other electric facilities turned off when we leave the rooms. Try to form the habit of turning off the tap immediate after using it. What’s more, papers should be printed on both sides and reused if possible.
I'd like to tell you something more about the problem of pollution we are facing to. As we know, the factory besides our school gives off heavy smoke all day long. Very loud voices hurt our ears. Rubbish and waste are thrown here or there. It also sends out polluting water and poisonous gas. All this has made a great harm to the health and study of the teachers and students. But as time goes on, a little has done to change the situation. I don't think we could study well unless the problem is solved. We do hope you'll help and support us.
My husband 96-year-old grandmother came to live with us for many years of independence. We did all the things we could make her feel comfortable, in our home, including giving her the private telephone line for their bedroom One evening we were having a party while the phone rang. It was a telephone operator, who asked, “Do you have a grandmother on upstairs? “Yes, what was happened?” my husband replied. “Well,” the operator again continued, “She can't remember your phone number, and she like a cup of tea.”
A US-led War against Iraq broke out in March 20, 2003 without the agreement of the UN. They came less than two hours after Bush's deadline for Saddam leave his country has passed. There are about 250,000 US armies around Iraq. There are also armies from another countries, includes Britain and Australia, fighting with the American soldiers. Their force is much more bigger than that of Iraq. But they met strong resistance than they expected. “These things are never easy. There will have some difficult times ahead so the War is going on as its plan,” said British Prime Minister Blair.
There are strange similarities in the life of John F. Kennedy and the life Abraham Lincoln. For example, Kennedy became a president in 1960, while Lincoln elected in 1860.This was exactly one hundred years apart. Then both men were shot after, on a Friday and in the presence of their wife. There is another very strangely similarity. Kennedy's secretary, named Lincoln, told him to go to Dallas. Lincoln's secretary, named Kennedy, told him not to go to the Ford Theatre. But all of them went and both were shot to die.
If there are much more people in the world, there must have more food to feed the people. But food is already a problem in today world. One-third of the world's population is starving, because there is not enough food. Ten thousand people died of hunger every day in some parts of the world. But in others parts of the world, people become ill or die, because they eat too much food, and they are very fat. Some countries have no food, but the others have too much, and they throw them away. How can tomorrow's world feed its people? The world needs produce more food than it does now.
