If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don’t even think when we do it. It has become a part of our lives.

“Early to bed, early to rise makes a man healthy, wealthy and wise.” This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever.

Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours’ sleep every day.

Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can’t be healthy, wealthy or wise.

When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don’t exercise, our body will become weak.

Exercise helps the blood (血液) to move around inside our body. Blood takes food to all parts of our body.

Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise.

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to using horses, carriages and bicycles.

In the Second World War, some people didn’t use gas made from petroleum (石油) in their cars. They made gas from wood and plants instead. The car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all our trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity to run our cars, but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines (涡轮机) and make electricity more easily and cheaply.

We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.

Which of these ways will be used to run our cars in the future?

Producing money requires both artistic and technological skills． Dollar bills are made so that they are interesting to look at but very hard to copy． In total, there are sixty-five separate steps required to make a dollar bill．

The money making process begins when． a yearly order is sent by the Federal Reserve Board． That order will then be divided in half． Half will be done here in Washington, D．     C．and the other half will be done in Fort Worth, Texas． Next, the Bureau orders special paper which is actually cloth since it is 75% cotton and 25% linen．

This paper is made so that it can last a long time． And, it is made with details that make it hard to copy． For example, bills contain security threads． These narrow pieces of plastic are inside the paper and run along the width of the bill． This special paper is also made with very small blue and red fibers．

Once the money is printed, guillotine cutters separate the sheets into two notes, then into individual notes． The notes are organized in "bricks," each of which contains forty one-hundred-note packages． The bricks then go to one of twelve Federal Reserve Districts, which then give the money to local banks． Ninety-five percent of the bills printed each year are used to replace money that is in circulation, or that has already been removed from circulation．

You may know that America's first president, George Washington, is pictured on the one- dollar bill． But do you know whose face is on the two, five, ten, twenty, fifty and one hundred-dollar bills? They are, in order． President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin．

The average life span of a one-dollar bill is twenty-one months． But a ten-dollar bill lasts only about eighteen months． The one hundred-dollar bill lasts the longest, eighty-nine months． One popular question is about the two-dollar bill． This bill is not printed very often． This is because many Americans believe two-dollar bills are lucky, so they keep them．

A very special teacher in a high school had a husband who died suddenly of a heart attack. About a week after his death ,she 36______ some of her thoughts with a classroom of students. with a 37_______ look on her face, she 38_______ and said, "39_______class is over, I would like to share with all of you a thought which I feel is very 40_______.
