Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about drinking is the key to critical（判断性的）thinking. When you think critically, you take control of your thinking processes（过程）. Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.
The word “critical” here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen-beyond the pictures on TV, the untrue reports in the newspapers, and the faulty reasoning.
Critical thinking is an attitude as much as an activity. If you are curious about life and desire to dig deeper into it, you are a critical thinker. If you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker 。
Activities of the mind and higher-order reasoning are processes of deep and careful consideration. They take time, and do not go hand in hand with the fast speed in today’s world: fast foods, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure of intelligence（智力）, you may learn something new from a story about Albert Einstein. The first time Banesh Hoffman, a scientist, was to discuss his work with Albert Einstein. Hoffman was too nervous to speak. But Einstein immediately put Hoffman at ease by saying, “Please go slowly. I don’t understand things quickly.”
73. Critical thinking is important to us because if we do not think critically, _______.
A. it will be hard for us to think naturally and fast
B. we might be controlled by other people’s ideas
C. we will follow the ideas of others naturally
D. we might be footed by other people’s ideas
74. If you are a critical thinker, you will ________.
A. think deeply about different ideas    B. trust the reports in the newspapers
C. take one view against another view D. criticize other people for their mistakes
75. In the last paragraph, “something new” suggests that ________.
A. the smarter you are, the faster you do things
B. the faster you do things, the smarter you become
C. speed can improve intelligence
D. intelligence is not decided by speed
76. What would be the best title for the passage?
A. Thinking and Critical Thinking.          B. Understanding Critical Thinking.
C. Thinking Is Natural and Human.      D. Thinking Fast Means Intelligence.

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water．But it also leads to a fossil fuel．Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years．Burning it releases fewer pollutants than oil or coal．The gas is mainly methane （甲烷）．It produces half the carbon dioxide of other fossil fuels．So it may help cut the production of carbon gases linked to climate change．
Russia is first in what are called "proved reserves" of natural gas．The United States is sixth．Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America．They drilled straight down into formations where gas collects．As these supplies were used up, big drillers looked for similar formations in other countries．
But now the industry is taking a new look．Companies are developing gas supplies trapped in shale （页岩） rock two to three thousand meters underground．They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock．This causes the rock to fracture, releasing the gas．Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states．Gas shale exploration is being done mainly by small to medium sized companies．Eric Potter, a program director, says more than half the gas in the United States is now coming from these new reserves．
But hydraulic （液压的） fracturing can also produce debate and anger over the risk of groundwater pollution．This method of drilling is not federally supervised under the Safe Drinking Water Act．Some in Congress want to end that exemption （豁免） from the law．
Natural gas provides Americans with about one fourth of their energy．And, unlike oil, most of it is produced in America．Gas producers invested heavily in reaching new supplies when prices were high．But prices are down sharply now because the depression cut demand for energy．So energy expert Eric Potter says it is too early to know how the changing market prices will affect the market for gas shale exploration．
45．We can learn from the first paragraph that ________．
A．natural gas releases methane and carbon dioxide
B．natural gas is considered as the cleanest energy
C．natural gas is more environmentally friendly than other fossil fuels
D．natural gas is a renewable source of energy
46．The word “fracture” in Paragraph 4 probably means _______．
A．create         B．break          C．change         D．decrease
47．Gas shale exploration may cause disagreement because ______．
A．it may cause water pollution      B．it brings too high profits
C．it breaks the law                D．it is out of states’ control
48．According to Eric Potter, the new gas shale exploration ______．
A．will provide America with about one fourth of their energy
B．will increase demand for energy
C．will make gas producers invest a big sum of money
D．may be influenced by the changing market prices

For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.

In 1867 the United States faced the task of rebuilding after the destruction of the Civil War, so it looked westward for the raw materials needed to fuel industrial growth. Geological surveys and mapping journeys were set forth to explore this 1 territory. These groups, in turn, hired mapmakers, scientists, cooks, drivers, and doctors. They also hired painters and photographers as part of the teams. Painters needed few supplies, making it relatively easy for them to travel in the wilderness, ____2____ photographers were not so lucky; they had to transport a fully stocked darkroom on the __3____.

Until the late 1870s, most photographers used the __4___ wet-collodion process. The first step was to wash a clean sheet of glass with a sticky mixture of collodion and chemicals, (collodion or "gun-cotton" was a recent medical discovery used to cover wounds because the viscous (粘性的) solution turned into a protective film when dry.) After it was washed, the plate went into another bath that the picture was __5___ getting darker; Finally, the glass negative (底片) was washed clean with fresh water. __6__ a photograph from the negative had to wait until the photographer went back to the studio. The ___7___ of the negative depended on the size of the camera. Some negatives could be as large as 20 by 24 inches.

Imagine the __8____ of taking photographs in the 1860s and 1870s in the remote western wilderness! Photographers went over Rocky Mountains and through rushing rivers. They were __9____ in the terrible desert heat, with cameras, sheets of glass, and vats of chemicals. Bad weather, equipment failures, and accidents were frequent problems. They persevered, but success in creating a negative did not ___10___ the production of a photograph; plates still had to be ___11___ transported back to the studio before the image could be printed on paper. A photographer could carry 120 pounds of many miles to ____12____ a magnificent view only to have the easily broken plate ___13___ in transportation.

__14___, once photographers were successful, the results were superb and much admired. Photographs were put on exhibition, and people bought albums filled with pictures by Timothy O'Sullivan, Carleton Watkins, and William Henry Jackson. Jackson's photographs of Yellowstone's

natural wonders, along with the paintings of fellow Thomas Moran, even helped ___15___ Congress to preserve thousands of acres of this land in 1872 as the nation's first national park.
