Centuries ago, man discovered that removing moisture (湿度,水分) 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 110℃ at entry to about 43℃ at exit．This is the usual method for drying such things as vegetables, mincemeat 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 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 convenient 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.
64．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
65．The underlined word “conventional” in Paragraph 3 can most probably be replaced by _______.
A．particular B．scientific C．usual D．special
66．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.
67．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

A typical (典型的) Chinese Internet user is a young male who prefers instant messaging to e-mail, seldom makes online purchases and favors news, music and games sites．According to a study, about two-thirds of survey participants (参与者) use the Internet for news — often entertainment-related — or for online games．About half download music and movies.

Beijing — Premier Wen Jiabao has urged the leadership of all countries to deepen their political will in tackling climate change woes (灾难) as uncertainties mount in the months before the United Nation’s conference in Cancun, Mexico, at the end of this year.
Wen made the remarks on Friday when he met with nearly 20 politicians, climate change and environmental ministers worldwide, who are in Beijing this weekend to attend an international forum on green economy and climate change.
Based on the achievements made at the Copenhagen Summit last December, Wen urged the rich countries to further clarify their compulsory carbon reduction targets. “At the same time, we developing countries should make clear our voluntary goal of slowing down climate change,” Wen said.
Wen also urged the developed countries to transfer climate change friendly technologies to the developing countries, especially the poorest countries and island nations.
During the meeting, Wen said China will redouble its efforts in reducing carbon emissions and improving energy efficiency during the coming years after it finishes its 2006-2010 goal of cutting energy consumption per unit of economic output by 20 percent.
While praising China for its green efforts, former Australian Prime Minister Robert J. Lee Hawke asked China to share its experiences and lessons on energy savings and pollution reduction to the rest of the world to tackle global environmental woes and climate change.
Wen responded: “China, together with the rest of the world, is willing to make its due contribution in coping with global warming and climate change.”
At a banquet for the foreign guests on Friday night, former vice-premier Zeng Peiyan said mounting uncertainties are ahead for the climate change negotiations. The world needs more dialogue and cooperation, Zeng said.
“Climate change woes are our shared challenges but the root lies in the historical emissions by the developed countries,” said Zeng, as president of the China Center for International Economic Exchanges, which organized the weekend climate change summit.
Zeng expected the forum to work as a platform for different countries to communicate their positions freely before the Bonn climate change negotiation in June and the Cancun conference at the end of this year.

California is the most populous state in the United States, and the third largest by land area, after Alaska and Texas. California is located on the West Coast of the United States, bordered by Oregon to the north, Nevada to the northeast, Arizona to the southeast, the Mexican state of Baja California to the south, and the Pacific Ocean to the west. Its four largest cities are Los Angeles, San Diego, San Jose, and San Francisco. The state is home to the nation’s second and sixth largest census statistical areas as well as eight of the nation’s fifty most populous cities. California has a varied climate and geography, and a diverse population.
California’s geography ranges from the Pacific coast to the Sierra Nevada mountain range in the east, to Mojave desert areas in the southeast and the Redwood — Douglas fir forests of the northwest. The center of the state is dominated by the Central Valley, one of the most productive agricultural areas in the world. California is the most geographically diverse state in the nation, and contains the highest (Mount Whitney) and lowest (Death Valley) points in the contiguous United States. Almost 40% of California is forested, a high amount for a relatively arid state.
Beginning in the late 18th century, the area known as Alta California was colonized by the Spanish Empire. In 1821, Mexico, including Alta California, became the First Mexican Empire, beginning as a monarchy, before shifting to a republic. In 1846 a group of American settlers in Sonoma declared the independence of a California Republic. As a result of the Mexican-American War, Mexico ceded California to the United States. It became the 31st state admitted to the union on September 9, 1850.
In the 19th century, the California Gold Rush brought about dramatic social, economic, and demographic change in California, with a large influx of people and an economic boom that caused San Francisco to grow from a hamlet of tents to a world-renowned boomtown. Key developments in the early 20th century included the emergence of Los Angeles as center of the American entertainment industry, and the growth of a large, state-wide tourism sector. In addition to California’s prosperous agricultural industry, other important contributors to the economy include aerospace, petroleum, and information technology. If California were a country, it would rank among the ten largest economies in the world, with a GDP similar to that of Italy. It would be the 35th most populous country.

47. What is the second paragraph mainly about?
A. California’s culture B. California’s history
C. California’s location D. California’s geography
48. How did the United States admit California as its 31st state?
A. By occupying the land. B. By colonizing the land.
C. By winning a war against Mexico. D. By offering aids to Mexico.
49. Why did San Francisco grow from a hamlet of tents to a world-famous boomtown?
A. Because it became the center of the American entertainment industry.
B. Because it had the best growth of a large, state-wide tourism.
C. Because a large number of people rushed there in search of gold.
D. Because it developed many such important contributors to economy as IT.
50. What if California were a country?
A. It would be richer than Italy, a European country.
