Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.

  Beginning in the middle of the 20^th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.

  By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.

  So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.

  By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.

  So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.

Our nearest neighbor is the moon. In the sky,  the moon and the sun seem to be of the same size because the moon is much nearer.
The moon makes the tides—the changes in the level of the sea. The moon and the sun together pull the sea. In some parts of the world,  the difference between * high tide’ (when the sea is very near to the land) and ’ low tide’ (when the sea is far away from the land) is very big. This is very important for ships.
The moon is very different from the Earth. Gravity on the moon is six times weaker than that on the Earth. There isn’t any air. During the day,  it is very,  very hot but at night it is very,  very cold. Nothing can live on the moon.
If the moon goes between the Earth and the sun,  we have an eclipse of the sun(日食) . The moon stops the light from the sun and we have night in the day.
If the Earth goes between the moon and the sun,  we have an eclipse of the moon. The moon goes into the shadow( 影子) of the Earth and it disappears for a few minutes.
【小题1】When the moon goes between the Earth and the sun,  we have night in the day, we call it the eclipse of

Where do our favorite foods come from? The truth may surprise you. Did you know curry isn’t Indian? Did you know Americans weren’t the first to eat hamburgers? Or did you know pizza wasn’t created in Italy?

First, let’s talk about curry.     1.     But in reality(事实)， wealthy English people were cooking with curry spices (香料) hundreds of years before British ships traveled to India.

   2.     Cooks of wealthy English families created curry dishes, and later these dishes became popular in other parts of England.

   3.    The Persians were eating round, flat bread with cheese in the 500s-nearly one thousand years before pizza became popular in Naples, Italy!

Finally let’s look at the truth behind hamburgers. Many people think hamburgers are an American food.    4.    A German named Otto Kuasw made the first hamburger in 1891. Four years later, German sailors introduced hamburgers to Americans.

Where foods come from isn’t nearly as important as how they taste—delicious!   5.
