Read the following article and select the best answer. Article: Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, about 68 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue. Question: The word 'carcinogenic' most nearly means ' _ '. - trouble-making - color-retaining - money-making - cancer-causing
cancer-causing

(Question)
Read the following article and select the best answer. Article: Across countryside, non-food crops are growing alongside wheat.Some are used in new alternatives to plastics and other materials, but others will simply be burned. Burning crops is becoming more popular because it is good for the planet.Doing so is also cheaper than burning fossil fuels.As more land is devoted to non-food crop production, the economics of crops for fuel are likely to become even more favorable. Humans have been burning such biomass--organic materials from plants or animals-- since they discovered fire.But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion. Even allowing for emissions of carbon dioxide from fuel used in planting, harvesting, processing and transporting biomass fuel, replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90 percent. Power stations around the world are experimenting with forms of biomass to add to their coal or oil, with encouraging results.Indeed, power companies could profit by turning to biomass, especially when the subsidies many governments offer for using renewable energy are taken into account. Farmers can benefit from growing biomass.In Europe, the reduction of subsidies for certain crops is exposing farmers to market forces.Instead of being paid for whatever they produce, farmers must seek a clear demand for their product.Many believe that the demand for alternatives to fossil fuels could be just such a driver. But while biomass offers a variety of potential alternatives, the world's infrastructure has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted. Also, there are problems with using biomass.Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment, few are built to run on biomass alone.Burning some forms of biomass also causes environmental problems.Oils and waste can be smelly, while wood... Question: For coal-fired power stations, _ . - more effective ways to use biomass have been tried - using renewable energy has become their daily task - burning biomass alone would require considerable changes - setting up dependable supply channels needs governments' support
(Answer)
burning biomass alone would require considerable changes

Question: Read the following article and select the best answer. Article: LAST week's decision by the International Astronomical Union (IAU) to _ Pluto _ its planetary status, held since its discovery in 1930, has made a lot of people sad. "Pluto," American science writer Dava Sobel writes in her book "The Planets", "still has an emotional hold on planethood. People love Pluto. Children identify with its smallness. Adults felt it hard to accept its isolated existence." Many people felt sorry about Pluto's demotion . "I just cannot accept this at this time," says Liu Ming, 29, who runs a small company in prefix = st1 /Shanghai. "I was taught that 'the Nine Great Planets' formed our solar system since primary school. And now they suddenly decrease the planets to eight. This will take some time for most of us to absorb it," says Liu. Ordinary people are simply not used to it, but for some professionals, especially the persons in charge of planetariums and educators, the change has become a real headache. The "eight instead of nine" change will affect thousands of planetariums around the world. Schools will also be greatly affected. InChina, teachers are anxious as outdated textbooks are printed and given out to the remotest corner of the country for school children ready to start a new term soon. According to the Ministry of Education, new textbooks with changed contents will not be available until next year. Zhao Zhiheng, a member of the Astronomy Association from Tianjin, suggested that primary and middle school teachers be trained in the improved knowledge, and that the media carry more stories to let people know about the change as soon as possible. Question: What's the feeling of ordinary people to the change? - They thought it necessary to have a change. - They accepted it without hesitation. - They felt a little sad and not used to it. - They were strongly against the change.
