People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. The process of canning is much more recent. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.
Canning uses heat to kill bacteria and other micro-organisms that cause poisons to form in food. Canning also takes away the air that these organisms need to live. One popular method of canning uses a water bath.
Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. Firmer fruits and most vegetables are usually cooked. They take up less space in the bottles. After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. Then covers are placed on the bottles, but are not turned all the way. The bottles are placed in a large container filled with warm water that is then brought to a boil. The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. This makes a strong barrier to keep the air out. In other words, a vacuum is created. When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between four and twenty-one degrees Celsius.
Canning allows your family to enjoy foods that might not come fresh throughout the year. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.
You can get more information about canning food from the group, Volunteers in Technical Assistance. VITA is on the Internet at vita.org.

C
Isn"t it astonishing how much time we spend talking about food? “Have you ever eaten …?” “What did you have for lunch?” and so on. And yet when you travel from one country to another, you will find that people have quite different feelings about food. People often feel that what they eat is normal (正常) and that what other people eat is strange or silly. In most parts of Asia, for example, no meal is complete without rice. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day.
The sort of meat people like to eat also differs from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealanders eat sheep, but they never eat goat meat. The Japanese don"t like to eat sheep meat because of its smell, but they enjoy eating raw fish (生鱼).
So it seems that although eating is a topic we can talk about for hours, there is very little common sense in what we say it. People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits.
64. Which of the following is true according to the article?
A. All people have the same feeling about food.
B. In most parts of Asia, people usually have rice for meals.
C. People often consider other people to be strange or silly.
D. The topic people spend time talking about is bread and meat.
65. People in different countries   ___ .
A. drink the same sort of wine     B. have the same eating habit
C. eat different kinds of meat      D. have the same tea at different time within a day
66. The Japanese don"t like to eat sheep meat    __ .
A. because they dislike its smell   B. because it is too expensive
C. because it is easy to go bad    D. because they think it will do harm to their health
67. English people drink tea four or five times a day    _  .
A. because they get thirsty easily     B. because there is plenty of tea in Britain
C. because of their drinking habit    D. because they have enough time to do so

   The fact that blind people can see things using other parts of their bodies apart from their eyes may help us to understand our feelings about color. If they can sense color differences, then perhaps we, too, are affected (影响) by color without knowing it. Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings (包装), that blue foods are considered not agreeable to the taste ,and that cosmetics (化妆品) should never be packed in brown. These discoveries have grown into a whole subject of color psychology (心理学).
Some of our preferences (偏爱) are clearly psychological. Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement. Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people’s mind. People in bright red surroundings (环境) show an increase in breathing speed, heartbeat and blood pressure. Red is exciting. Pure blue has exactly the opposite effect; it is a calming color. Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.
65. The passage tells us that salesmen have _______.
A. found out that colors affect sales
B. discovered the relationship between color and psychology
C. tried colors on blind people
D. developed a special subject of color psychology
66. If people are exposed to (置身于) pure blue, _______.
A. their body pressure rises                    B. they won’t easily feel nervous
C. they want to taste blue foods          D. they will feel like buying things
67. The most effective color in the passage for warning people is _____.
A. red    B. bright yellow    C. dark blue    D. green
68. Which of the following do you think is the best title of the passage?
A. Color and Feelings                B. Colors and Sales
C. The Blind and Colors             D. Preferences for Colors

　　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 of oranges this year.
　　But Ed has to fight 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 Rawlings is prepared for the frosts(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 on 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 sucked in by the fruit and keeps its temperature at a safe level. Ed Rawlings has effectively used this method(方法)to save many orange crops.
　　But Ed still faces some difficulties. The trees should be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thick layer of ice that will break the trees" branches. 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 Rawlings with some of these worries. With equipment, air and soil temperatures and wind speed can be measured. The information is fed into a computer which can tell when temperatures drop to freezing. The computer can correctly decide the quantity of water to be used and how frequently the trees should be watered. Ed Rawlings will find looking after his orange trees a lot easier with the help of a computer, and we"ll all have the benefits(or advantages)of computer-age oranges.
