Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida’s weather. Warm sunshine and gentle rains, along with Ed Rawlings’ expert care, will produce a good crop（收成）of oranges this year.

However, Ed has to guard against Florida’s changeable winter weather. In January and February, temperatures can destroy Ed’s entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer(层) of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.

What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops.

But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity(数量)of water must be used. Too much water can form a thicker layer of ice that will break the tree’s branches(树枝). Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.

Computer technology may help Ed with some of these worries. With equipment(设备), air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate(计算) when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently(  ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits(利益) of computer—age oranges.

If the eyes are the windows of the soul, then the body is the mirror of our feelings. If we are feeling great, we may give our body signals(信号). If we look at someone else’s body, we can often tell how they are feeling by their body signals. So reading body language signals is a great tool in daily communication.

    In case(假使) you don't think that learning how to read and use body language is important, here are some numbers for you. 7% of the information we receive is from what people actually say, and 38% of the information we receive is from the tone(语气) and the speed of their voice; while 55% of the information we receive is from their body language.

    These non-verbal(非口头的) signals will help you a lot, but you still need to focus on what people are saying. If you focus too much on their body language signals, you and the person may feel uncomfortable. It is useful to be able to read people’s body language, but it is useful to learn how to send the right signals and avoid the wrong signals too. Body language may be given several interpretations. Many signals have different meanings, depending on the person and the situation. Be sure of it when you are trying to read a body language signal.

 Want to say "hello" from Disneyland? Send a post card!

Beautiful scenes of paradise (乐园), wild animals, silly pictures — you can find them all in one place. Where? On a post card! Have people always sent post cards? No. Before post cards, people liked sealed letters.

The idea for the first decorated (装饰) post card came to John P. Charlton in 1861. He thought a simple card with decorations would be a great way to send a note. Then in the late 1800s, post cards with pictures appeared. By law, people had to write their note on the front ——on the picture! The back was only for the address. Several years later, England allowed a divided-back post card. Then people could write their note on the back left side and put the address on the right. During the early 1900s, the golden age of post cards, picture post cards became a craze of the world. In 1908, Americans alone mailed over 677 million post cards. Today, post cards are the third most popular collection in the world after stamps and coins.
