Carrots are grown all over the world. They are easy to plant and easy to harvest. They have a good taste.

When people think about carrots, they usually think they are a kind of long, thin, orange-colored vegetable. In fact, carrots are in many different sizes and shapes. And not all carrots are orange.

Carrots should be grown in a field that does not have water for a long time. The earth also should not be too hard. To prepare your carrot garden, dig up the earth and turn it over(翻土). 

Weather, soil condition(土壤状况), and time affect(影响) the taste of carrots. Warm days and cool nights are the best time to grow great delicious carrots.

The best way to decide if a carrot is ready to be harvested is by its color. Usually, the brighter the color is, the better the taste is.

Most people do not know that carrots can be grown during the winter months. If the winter is not cold enough to freeze the ground, you can grow carrots the same way as you do during the summer months.

Carrots are prepared and eaten in many different ways. They are cut into thin pieces and cooked with other vegetables or meat. Or, they are washed, and eaten just as they come out of the ground.

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we're thankful for turned out to be what they are.

1. Most historians hold that the Chinese invented fireworks in the 9^th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for "Pemberton's French Wine Coca", his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C's would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.

3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.

    Do you know what the White House is? Perhaps some of you do，while others don't.

    The White House is a house in Washington. The president of the U.S.A. lives in it. It's really white. But do you know why the White House is white? The story happened in 1812. That year England was at war with America. The British army got to Washington and set the president's house on fire. In 1814，in order to hide the marks of the fire，the stone walls of the president's house were painted white and it has been the “White House” ever since.

    Audrey is a Chinese-American student. She has found value (价值) differences between Chinese and Americans.

    About money:

    ①Americans would like to spend more than they have, so many of them are always in debt (欠债). Chinese usually spend less than they have, so many of them always have money left in the bank.

    ②American kids love to make money by themselves. Chinese kids always ask their parents for money.

    ③Americans parents think that it is not useful to send their children to an expensive university. Chinese parents would do anything to send their children to good universities and that might make them very poor sometimes.

    About school:

    ①Many American girls take part in sports, dancing and singing groups while Chinese girls take part in academic groups.

    ②Some American students think that "B" is a gift while Chinese students think that "B" is terrible.
