Read the following article and select the best answer. Article: High-tech gadget shows draw throngs of excited consumers each year in the United States, Japan, Europe and the Arabian peninsula. Though many people are already surrounded with all kinds of smart electronic devices, some always need one more -- better and smarter than the previous one. At electronic shows, visitors flock around the newest tablet computers, cameras, 3D television screens, even small robots, dreaming of taking one home. Consumers spend hours waiting in lines and spend hundreds of dollars to be among the first to get the latest smart phone. The modern world seems to _ shiny expensive objects that keep us connected, help us navigate, record our thoughts and memorable events, and even talk to us. So infatuated, we no longer merely "own" our gadgets -- we have relationships with them, according to clinical psychologist and life transition therapist Francine Lederer. "It's a lot easier to have, right, a one-sided relationship with your computer, your phone, than it is with a live person. So that at the end of the day, you don't need to worry about somebody being angry with you, you don't need to worry about getting blamed for anything," she said. Magical devices Although having a thousand Facebook friends may be perceived as equivalent to having a thousand real, authentic friendships, Lederer said in reality it is not so. "It comes down to a lot of the internal stuff. How we feel about ourselves, our own sense of self-esteem, our self-worth, a lot of those things," she said. But gadgets are magical. They fascinate us the same way we are intrigued by a magician's trick, said psychology professor at the University of the South Pacific, Robert Epstein. "If you don't know how they're doing it, that's very fascinating and intriguing. But if they do it 10 times or 20 times or 100 times, it gets boring and you want something else. That's why magicians do not repeat the same trick over and over again," he said. Plugged in, isolated Epstein, former editor-in-chief of Psychology Today magazine, said he is... Question: What is Lederer's opinion? - It's abnormal for us to rely on electronic gadgets too much. - Gadgets will take on a life of their own. - It's healthy for us to use model electronic gadgets. - The gadgets will be built into us to some extent.
It's abnormal for us to rely on electronic gadgets too much.

Read the following article and select the best answer. Article: My first visit to Angkor Wat was in 1980. The country had been at war for many years and _ and falling to pieces. Plants were growing out of the roofs, and trees were growing in the courtyards. Today, the temple is the scene of a busy repair program. A team of 15 Indian experts are organizing a workforce of 400 Cambodians, most of them women, who are cleaning, repairing and rebuilding parts of this temple. As I walked through the courtyards, I noticed the Cambodian women devote hours to cleaning carefully a tiny area of stone. Boards are laid down to protect the precious painted stones while the repair work is going on. There are very few machines and little heavy equipment. Workers carry building materials in buckets at the end of long poles. Piles of stones lie in a corner of the courtyard, waiting to be replaced. The work of cleaning the stones is watched over by three Indian chemists. It is a very slow task. First they clean the stones with brushes using buckets of a weak chemical. Then gaps between the stones are filled in. Finally another material is painted onto the stones which will protect them from water forever. Work starts every day at 7 a. m. and goes on until late afternoon six days a week, with a break at midday. Evening is the best time to visit the temple, after the tour groups have left. As the sun sinks lower, shadows spread across the courtyard. After sunset, the sky turns pink. The grey stone towers take on a golden color before turning pink. Nowhere else in the world can there be such a quiet, beautiful place. Question: According to the author, which of the following plays the LEAST important role in the repair work? - The women workers. - The Indian workers - Machines - Skilled workers
Machines

Q: Read the following article and select the best answer. Article: The US will seek to expand its own oil production in an attempt to reduce dependence on imported oil and bring down fuel prices , President Obama says . New contracts for exploration will be signed in non-protected areas of Alaska and in the Gulf of Mexico. In his weekly speech , the President insisted the US could reduce its need for imported oil and improve safety. Using his speech to tell Americans that he understood their concerns about rising prices, President Obama focused particularly on the price of fuel, which has risen in recent months. US consumers have historically enjoyed cheap fuel , but have seen prices rise in recent months even though US oil production in 2010 reached its highest level for seven years. Although the oil spill in the Gulf of Mexico in 2010 was serious, Mr Obama said the Gulf remained a key part of the country's future energy supply. The President's proposals come after Republicans introduced a series of proposals that would expand and speed up oil and gas production. The White House has criticized the Republican proposals for safety reasons , but Mr Obama was clear in his speech that he felt safety and environmental standards could be maintained even though production might rise. " I believe that we should continue to expand oil production in America --even as we increase safety and environmental standards ,"he said. "As a nation, we should be investing in the clean, renewable sources of energy that are the solution to high gas prices." Mr Obama has previously called for a step-change in energy policy, saying the US must move towards getting 80%of its electricity from clean energy sources by 2035. Question: What can we learn from the text ? - The US has got most of its electricity from clean energy. - US oil production is too small to keep the present low fuel prices. - The US produced the most oil in 2010 in its history. - The Gulf is still important in energy supply in spite of the oil spill in 2010.
A: The Gulf is still important in energy supply in spite of the oil spill in 2010.

Q: Read the following article and select the best answer. Article: What do astronauts eat in space, and why? How did astronaut food come into being? How do astronauts preserve food for long periods of time in space? NASA(the National Aeronautics and Space Administration) has been researching food for space travel since the 1960's to find the best way of keeping astronauts from going hungry. The research could date from an accident that took place on the first manned Gemini mission in 1965. astronaut John Young managed to sneak a corned beef sandwich onto the Geminni III capsule to eat during its orbit around Earth. To Young's surprise, the sandwich plan did not go as expected; instead the sandwich began to break apart and scatter through the Geminni IIIcapsule. This could have resulted in disaster, since a small piece of food could have stuck in the air vents and other equipment. The sandwich was stuffed into a pocket to avoid the further mess inside the small space capsule This incident caused NASA to enforce strict rules on what types of food can be taken into space. Space food has come a long way since then. During the Gemini period, the astronauts mostly ate cubed, compressed foods high in calories and lightweight. NASA expects a long shelf life for space food. The majority of food taken into space has been dried out or heat-treated. These process and use of sodium , make the food taken into space last longer. Research is ongoing into space food to seek out healthier ways to preserve it. Too much sodium is unhealthy, and can badly change the taste of some foods. Question: What happened to John Young in the Geminni III capsule? - His sandwich went bad as expected - He couldn't eat the sandwich he had bought - His sandwich caused trouble to some equipment - He filled his pocket with the sandwich.
A: He couldn't eat the sandwich he had bought
