Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions
         Simply being bilingual doesn’t qualify someone to interpret. Interpreting is not only a mechanical process of converting one sentence in language A into the same sentence in language B. Rather, its a complex art in which thoughts and idioms that have no obvious counterparts from tongue to tongue _ or words that have several meanings must be quickly transformed in such a way that the message is clearly and accurately expressed to the listener.
         At one international conference, an American speaker said, “You cant make a silk purse out of a sows ear”, which meant nothing to the Spanish audience. The interpretation was, “A monkey in a silk dress is still a monkey” _ an idiom the Spanish understood and that expressed the same idea.
         There are 2 kinds of interpreters, simultaneous and consecutive. The former, sitting in a separated booth, usually at a large multilingual conference, speaks to listeners wearing headphones, interpreting what a foreign language speaker says _ actually a sentence behind. Consecutive interpreters are the ones most international negotiations use. They are employed for smaller meetings without sound booths and headphones. Consecutive interpretation also requires two-person teams. A foreign speaker says his piece while the interpreter, using a special shorthand, takes notes and during a pause, tells the client what was said.
 
The author implies that most people have the opinion that the skill of interpreting is …..
A.very complex and demanding
B.based on principles of business
C.simpler than it really is
D.highly valued and admired

FREAKY FORCES OF NATURE
When Weird Weather Strikes
Most of us know about fires, hurricanes, droughts, and floods. But from time to time, Mother Nature  surprises us, and delivers a weather event that is really weird. Here are some examples of truly weird weather.
One day in 2005, residents  of a small town in Serbia looked out their windows and saw an unusual sight. It was raining frogs! Without any warning, they found their streets filling with the little jumping creatures. “There were thousands of them," one resident told a local newspaper. "I thought perhaps a plane carrying frogs had exploded,"  said another. Scientists think a tornado passed over a lake. It sucked up animals that lived there. The frogs were carried into the air. Then they were dropped in the Serbian town, far away.
As if tornadoes aren't dangerous enough, some of them can actually be made of fire. When a wildfire reaches very high temperatures, it causes the air to become hot and to rise. Cooler air rushes in to replace the hot air. This creates strong winds. These winds suck up burning plants and even the fire itself. When this happens, like it did on March 14, 2014, in Denver, Colorado, U.S.A., a tornado of fire is produced. This tornado can become 15 meters (50 feet) wide and grow as  tall as a 40-story building.
In 1942, hundreds of thousand-year-old skeletons were found under the ice of Lake Roopkund in the Himalayas. Many had holes in their skulls. But they weren't hurt in any other way. Scientists thought the people must have been hit from above. But for years, the cause of their deaths was a mystery. Today, scientists think these people were killed by giant hailstones—balls of ice. Hailstones form when raindrops high in the sky turn into pieces of ice. The ice pieces increase  in size until the wind cannot hold them up. This results in hailstones falling to the ground, often at speeds of over 160 kilometers (100 miles) an hour. For the unlucky people at Lake Roopkund, there was nowhere to run. They were all killed by the hailstones.
Another title for this reading could be_____.
A.Unusual Tornadoes
B.Humans vs. Nature
C.Strange Weather
D.Wild Weather

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.
Nature has always provided a stimulus for inventive minds. Early flying machines clearly were an attempt to emulate the freedom of birds. Architects and engineers have often consciously modeled buildings on forms found in nature. A more recent example of the inspiration given by nature is the invention of Velcro®. The inventor of this now common fastening device noticed that small burrs attached to his dog's coat grasped the hairs by means of tiny hooks. This led him to invent a synthetic fabric whose surfaces mimic the clasping properties of this natural seedpod.
   Animals and plants have evolved solutions to the kinds of problems that often interest engineers and designers. Much current research in material science is concerned with actively examining the natural world, especially at the molecular level, for inspiration to develop materials with novel properties. This relatively new field of study is sometimes known as biomimetics, since it consciously attempts to mimic nature.
Researchers have investigated several interesting areas. For example, they have studied how the molecular structure of antler bone contributes to its amazing toughness, how the skin structure of a worm contributes to its ability to crawl, how the sea cucumber softens its skeleton and changes shape so that it can squeeze through tiny gaps in rocks, or what gives wood its high resistance to impact. These investigations have led to several breakthroughs in the development of composite materials with remarkable properties.
Predictions for future inventions that may be developed from these lines of research include so-called smart structures that design and repair themselves in a similar way to a variety of processes in the natural world. For example, engineers have envisaged bridges that would detect areas heavily stressed by vehicle movement or wind. The bridge structure would then automatically add or move material to the weak areas until the stress is reduced. The same principle might be used to repair damaged buildings. Other new materials that have been imagined are substances that would copy photosynthesis in green plants in order to create new energy sources. The potential impact of biomimetic research is so great that the twenty-first century may come to be known as the "Age of Materials."

A.stimulate                   
B.captivate                   
C.imitate
