Centuries ago, man discovered that removing moisture(潮湿)from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind. In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes), the Scandinavians make stockfish and the Arabs dried dates.
All foods include water—cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria(细菌)which cause food to go bad is checked.
Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. Various methods are used, but in general, the fruit is spread out on trays in drying yards in the hot sun.
Nowadays most foods are dried mechanically. The method of such dehydration(脱水)is to put food in chambers through which hot air is blown at temperatures of about 110℃ at entry to about 43℃ at exit. This is the usual method for drying such things as vegetables, minced(切碎的)meat, and fish.
Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to the climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.
1.According to the text, the open-air method of drying food .

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the America from being discovered by the people of Europe.
The Atlantic Ocean is only half as big as the pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2,000 miles (3,200 km) wide.
There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than 2 miles (3.2 km) deep, but in some places it is much deeper. The deepest spot is near Puerto Rico. This "deep" measures 30,246 feet --- almost six miles (9.6 km).
Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships. We now have such fast ways of travelling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!
1. From the third paragraph, we can learn that ______ .
A. the Atlantic will dry up in 4,000 years' time
B. no river flows into the Atlantic ocean
C. it's hard to imagine how much water there is in the Atlantic ocean
D. the Ocean floor is rather flat
2.Suppose it's February 27th, 2000. You take a steamship to cross the Atlantic to North America, when will you probably get there?
A. On March 2nd B. On March 3rd
C. On February 28th D. In eight hours' time
3. What can you learn from the last paragraph of the passage ?
A. The Atlantic has grown smaller than it used to be.
B. The Atlantic had grown wider than it used to be.
C. Fast ways of travelling make the ocean grow smaller.
D. Fast ways of travelling make the ocean seem to grow smaller.

Some time ago, I discovered that one of my chairs had a broken leg. I didn’t think there would be any difficulty in getting it mended, as there are a lot of antique (古董)shops near my home. So I left my home one morning carrying the chair with me. I went into the first shop expecting a friendly reception (接待). I was quite wrong. The man wouldn’t even look at my chair.
The second shop, though slightly more polite, was just the same, and the third and the fourth. So I decided that my approach must be wrong.
I entered the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, "Would you like to buy a chair?" He looked at it over carefully and said, "Yes, not a bad chair. How much do you want for it?" "Twenty pounds." I said. "OK," he said, "I will give you twenty pounds." "It’s got a slightly broken leg," I said. "Yes, I saw that, it is nothing. "the shopkeeper answered.
Everything was going according to my plan and I was getting excited. "What will you do with it?" I asked. "It will be easy to sell once the repair is done." "I will buy it." I said. "What do you mean? You just sold it to me." "Yes, I know, but I have just changed my mind, I am sorry. I will give you twenty - seven pounds for it." "You must be crazy." he said. Suddenly the penny dropped. "I know what you want. You want me to repair your chair." " You are right," I said, "What would you have done if I had walked in and asked you to mend the chair?" "I would not have agreed to do that. We don’t do repairs, not enough money in it, and too much trouble. But! will mend this for you. Will you pay it for five? ".

Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy.
“Our most important finding was the difference between Canadians and the others,” said Professor Michel Claes,the lead author of the study.“Canadians focus on independence and negotiation.On the other hand,Italians,for example,exercise more control.We found Canadians seem to focus on negotiation in case of a conflict.”
Claes said Canada,France and Italy were selected for the study because they share important cultural and social factors.“We chose FrenchCanadians because they share the same language as France,and originally came from France and share certain values.Italy was included because it was considered to have similar,strong and important family values,” he explained.
The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old.
Canadian students reported less control and more free actions,according to the study.Italian parents were stricter and French parents were somewhere in the middle.
Claes explains that the differences lie in education in Canada,France and Italy.
“North America has its own educational values,which promote individualization.Tolerance and comprehension are encouraged.Italy,on the other hand,promotes respect of authority,control,and the need for permission.” he said.
Children from all three countries described their mothers as warm and communicative.Italian and Canadian children had similar feelings about their fathers,and reported high levels of emotional ties.But French fathers were generally thought by their children to be more distant and cold.
“We were surprised by this,” Claes admitted.“It seems as though the relationships between French mothers and their children were becoming closer over time,while fathers maintain a form of distance and coldness,which is more of a source of conflict in France than in the other countries.”
1.Professor Michel Claes believes that Canada,France and Italy ________.
A.have the same family spirit
B.have some similar cultural traditions
C.have experienced some similar social changes
D.have experienced similar cultural developments
2.How did the researchers carry out the study ?
A.By collecting answers of parents from Canada,France and Italy.
B.By collecting answers of children from Canada,France and Italy.
C.By questioning parents and their children from Italian Canadian families.
D.By questioning children from FrenchCanadian families.
3.According to Michel Claes,what mainly leads to the differences in parentchildren relationships among Canada,France and Italy?
A.Educational opportunities.
B.Traditional ideas.
C.Educational values.
D.Historical events.
4.Which of the following is NOT a finding of the study?
A.French children have troubled relationships with their parents.
B.Canadian children have close relationships with their parents.
C.Italian children have good relationships with their parents.
