Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind.
All foods including water — cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean (瘦的) 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 which cause food to go bad is controlled.
Nowadays most foods are dried mechanically. The conventional method of such dehydration (脱水) is to put food in chambers (室) through which hot air is blown at temperature of about ll0'C at entry to about 43'C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated steel cylinder (圆筒), then put them into a chamber through which a current of hot air passes. In the first process, the dried material comes off the roller (滚筒) as a thin film which is then broken up into small, though still relatively flakes (薄片). In the second process it falls to the bottom of the chamber as small powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients (成分) are dried separately and then mixed.
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.It can be inferred from the passage that ________.
A.the rattier fish contain as much water as the lean one |
B.the rattier the fish is, the more water it may contain |
C.a fatty fish holds less water than a lean one |
D.the water content of fish has nothing to do with the content of their fat |
The underlined word "conventional" in Paragraph 3 can most probably be replaced by _________.
A.particular | B.scientific | C.usual | D.special |
Which of the following statements is NOT true about drying food?
A.The removal of water in food helps prevent it from going rotten. |
B.The open-air method of drying food has been known for hundreds of years. |
C.In the course of dehydration, the temperature of hot current coming from entry to exit is gradually going up. |
D.The process of drying liquids is much more complex than that of drying solid food. |
The last paragraph mainly talks about __________.
A.the reason why housewives like dried food |
B.the general convenience of dried food |
C.the methods of storing food |
D.the advantages of dried, canned and frozen food |
There was a gardener who looked after his garden with great care. To water his flowers, he used two buckets(桶). One was a shiny and new bucket. The other was a very old and worn-out one, which had seen many years of service, but was now past its best.
Every morning, the gardener would fill up the two buckets. Then he would carry them along the path, one on each side, to the flowerbeds. The new bucket was very proud of itself. It could carry a full bucket of water without a single drop spilled(溢出). The old bucket felt very ashamed(惭愧的) because of its holes: before it reached the flowerbeds, much water had leaked along the path.
Sometimes the new bucket would say, “see how able I am! How good it is that the gardener has me to water the flowers every day! I don’t know why he still bothers with you. What a waste of space you are!”
And all that the old bucket could say was, “I know I am not very useful, but I can only do my best. I am happy that the gardener still finds a little bit of use in me, at least.”
One day, the gardener heard that kind of conversation. After watering the flowers as usual, he said, “you both have done your work very well. Now I am going to carry you back. I want you to look carefully along the path.”
Then the two buckets did so. All along the path, they noticed, on the side where the new bucket was carried, there was just bare(光秃秃的)earth; on the other side where the old bucket was carried, there was a joyous row of wild flowers, leading all the way to the garden.What was the old bucket ashamed of?

The new bucket made conversations with the old one mainly to ______ .
A.laugh at the old one |

A.Because it was used to keep a balance |
B.Because it stayed in its best condition |
C.Because it had its own function |
D.Because it was taken as a treasure(宝物). |
In the fall of 1985, I was a bright-eyed girl going to Howard University, aiming at a law career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different story to tell.
My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to leave college to care for her. It meant that school and my personal dream would have to wait.
Then I got married with another dream: building my family with a mix of adopted(收养)and biological children. In 1999, we adopted our first son. To put eyes on him was wonderful---and very emotional. A year later came our second adopted boy then followed son No.3. in 2003, I gave birth to another boy.
You can imagine how engaged I became, raising four boys under the age of 8! Our home was a complete zoo---a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up on the dream either. I had only one choice: to find a way. That meant taking as few as one class each term
The hardest part was feeling sorry about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to give up, but I knew I should set an example for them to follow through the rest of their lives.
In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!
I am not special, just single-minded. It always struck me that when you are looking at a big challenge from the outside it looks huge, but when you are in the middle of it, it just seems normal.

Exploit your parking space
An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement(广告)for free on Letpark or Atmyhousepark.
Rent(出租)a room
Spare room? Not only will a lodger(房客)earn you an income, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax (税) on the first £4,500 you make per year. Try advertising your room on Roomspare or Roommateeasy.

Don’t want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money, Grashpadder can advertise your space.
Live on set

It’s 5:00 in the morning when the alarm (闹钟) rings in my ears. I get out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD Insanity. Sweat pours down my face and into my eyes. My heart races as I force my body to finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is on my face. It’s not a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years, I have learned it’s okay to just say “no.” I shouldn’t feel sorry for refusing food that I don’t want to eat.
So what drives me to get out of bed at 5:00 a.m.? What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily worry, increases self -confidence and energy, extends (延长) life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It’s through commitment and sweat that I can make a difference within myself inside and out.Why is there a smile on the author’s face in the morning?
