C
Centuries ago, man discovered that removing moisture(湿气) 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 orfrozen, and they do not need to be stored in special conditions. For these reasons theyare invaluable to the climbers, explorers and soldiers in battle, who have little storagespace. They are also popular with housewives because it takes so little time to cook them.
54.It can be inferred from the passage that ________.
A.the fattier fish contain as much water as the lean one
B.the fattier 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
55.The underlined word "conventional" in Paragraph 3 can most probably be replaced by ______.
A.traditional B.scientific C.particular D.special
56.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.
57.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

Money, or the lack of it, changes everything, and that includes how people will be working out in 2010.
In these belt-tightening times 1 , cost-conscious workouts(锻炼)at home and at the gym topped the list of fitness trends for this year in a survey, followed 2 by shorter, more time-efficient regimens, such as 3 boot camp(强力集中训练) and circuit training.
"People are looking 4 for ways to accomplish as much as possible with as little 5 time and money as necessary," said Cedric X. Bryant, chief science officer of the American Council on Exercise (ACE), which conducted the online poll of fitness professionals.
"Last year money was on the list but this 6 year the majority of the respondents put 7 it as one of the top," he added.
Bryant said some 600 ACE-certified fitness 8 professionals responded to the annual poll 9 , which the non-profit organization has been conducting for a decade.
Other money-saving measures 10 , such as the shift from personal training sessions to small group training 11 classes and in-home workouts 12 using smaller, more portable equipment, also made the list.
"Personal trainers are seeing they've got to respond to market needs 13 . Working with two to four clients at a 14 time they can charge less 15 but still get their hourly fee," Bryant said.
Boot-camp workouts and circuit training, both of which burn 16 calories while building strength and endurance(持久性), will be among the most popular trends in 2010, as time-constrained(受压制的) consumers 17 seek shorter, more intense activities.
One bright spot is the rise of exergaming-type systems, like Nintendo's Wii Sports, Wii Fit and the PC-based Dancetown. Bryant says the fitness-based video games are turning up 18 in health clubs and senior centers.
Functional training workouts, which are geared to improving the quality of life and the ability to perform everyday tasks, will remain strong 19 , and the use of computerized tracking and online training and scheduling tools will increase 20 in the coming year.
