Article: It is 4 o'clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer "hackers" are tracing a sort of stimulus , a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted computer programmers. Some of these students have been glued to the console for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments' rest but hating to get too far away from their addicted machines. It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be -- they can not resist the attraction of the computers. Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health. "There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health," says a computing science professor at California University. Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe firmly that hackers are not simply resulted from the close relationship with a machine. It is the result of social relationship with the attractive thinking machines, which are becoming nearly universal.

Article: Recently a committee of the National Academy of Sciences inprefix = st1 /Washingtonreleased a report .It confirmed that world temperatures increased about six-tenths of a degree Celsius in the last one hundred years. The report also confirmed evidence that the level of carbon dioxide in increasing. The best information about climate in the past comes from tests of ice many kilometers deep in Antarctica and Greenland .These tests show that levels of carbon dioxide today are the highest ever measured .These findings have led scientists to believe that carbon dioxide is a major cause of climate warming. Carbon dioxide is released into the atmosphere when fuel is burned. Oil ,coal and wood are all fuels that release the gas .When biological waste breaks down ,it also releases carbon dioxide. However ,plants use carbon dioxide in the process called photosynthesis. This process provides food for almost all life on Earth. Some groups that support burning oil and coal want to increase the amount of carbon dioxide in the atmosphere . They oppose international efforts to control carbon dioxide. Some scientists believe that forests and trees are able to capture large amounts of carbon dioxide from the air. Some groups even suggest that an increase in carbon dioxide could cause plants to grow faster. A recent study inNorth Carolinafound that more carbon dioxide in the air could cause trees to grow faster .But the researchers found the effect appears to last for only three years. Another study showed that much of the carbon dioxide that is taken in by trees in released within three years. The study noted that leaves released carbon dioxide when they fall from trees and break down in the soil. Plants also naturally release carbon dioxide through the process of respiration.
Question: Which one is NOT mentioned in this passage that can be the source of carbon dioxide?
Options: (A) Oil (B) Trees (C) Wood (D) Soil
Asnwer: A
answer:
No

Article: Wal-Mart is not just the world's largest retailer . It's the world's largest company, which sells in three months what number-two retailer Home Depot sells in a year. Wal-Mart exercises its power for just one purpose: to bring the lowest possible prices to its customers. At Wal-Mart, that goal is never reached. The retailer has a clear policy for suppliers: On basic products that don't change, the price Wal-Mart will pay, and will charge shoppers, must drop year after year. But what almost no one outside the world of Wal-Mart and none of its 21,000 suppliers know is the high cost of those low prices. To survive in the face of its pricing demands, makers of everything from bikes to jeans have had to close US plants in favor of obtaining products from abroad. Indeed, the real story of Wal-Mart, the story that never gets told, is the story of the pressure the biggest retailer constantly applies to its suppliers in the name of bringing us "every day low prices". The giant retailer' s low prices often come with a high cost. Wal-Mart' s pressure can crush the companies it does business with and force them to send jobs overseas. Are we shopping our way straight to the unemployment line? Of course, US companies have been moving jobs offshore for decades, long before Wal-Mart was a retailing power. But there is no question that the chain is helping accelerate the loss of American jobs to low-wage countries such as Thailand. People ask, "How can it be bad for things to come into the US cheaply?" Sure, it's great to have bargains. But you can' t buy anything if you' re not employed. There is no question that Wal-Mart's drive to squeeze out cost has benefited consumers. By now, it is accepted wisdom that Wal-Mart makes the companies it does business with more efficient and focused. Wal-Mart itself is known for continuous improvement in its ability to handle, move, and track goods. It is legendary for forcing its suppliers to redesign everything from their packaging to their computer systems. It is also legendary for quite straightforwardly telling them what it will pay for their goods.
Question: How do suppliers meet the requirements of Wal-Mart?
Options: (A) To sell even more goods in three months. (B) To cut down the employment rate sharply. (C) To charge shoppers at a much higher price. (D) To run the business in a well-organized way.
Asnwer: D
answer:
Yes
