Q: Read the article and select the best answer. Article: Almost everyone suffers from a headache occasionally. But some people suffer from repeated, frequent headaches. What is headache? What causes it? What can be done about a headache? What research is being done on headaches? The dictionary defines headache simply as "a pain in the head." What most people mean by headache is a pain which lasts several minutes or hours. It covers the whole head, or one side of it, or perhaps the front or the back of the head. To add to the confusion about a definition, some people call tight feeling in the head a headache. A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early. If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control. The professional name for covering up a symptom is "masking" (,). A headache specialist once said, "Masking symptoms is not the best way of treatment." He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia while bleeding continues undiscovered. He added, "Sometimes it is wiser to stand still than to advance in darkness. A headache is important also because it interferes needlessly with normal, happy living. The employee with a headache does less work. In a flash of temper he may upset his fellow workers or customers, causing a direct of indirect loss to his organization. The mother with a headache suffers and disturbs the family. She upsets her husband and children. Question: Which is true according to the passage? Options: A: Headache may last several minutes. B: Headache maybe cover the whole body. C: Headache has nothing to do with others. D: Headache maybe anything except the tight feeling in the head.
A: A

Q: Read the article and select the best answer. Article: The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages. Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements. This is particularly troubling for countries with agricultural industries in areas dependent on irrigation . In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed. Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry. Question: The text is mainly about _ . Options: A: water supply and increasing population B: water use management and agriculture C: water redistribution and wildlife protection D: water shortages and environmental protection
A: B

Q: Read the article and select the best answer. Article: The way we cook is important. In many countries, the two sources of heat used for cooking are natural gas or electric stoves. The World Health Organization(WHO) warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year. Indoor air pollution results from the use of dangerous fuels and cook stoves in the home. WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking, heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4.3 million people die from household air pollution given off by simple biomass and coal stoves. These findings show that the home use of poisonous fuels is to blame for many of these deaths. These fuels include wood, coal, animal waste and so on. Carlos Dora is Coordinator in the WHO' s Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene fuel indoors. He says opening a window or door to let out the harmful air will not correct the situation. It will only pollute the outdoors. "New technologies and clean fuels can rid people of this problem." The United Nations found that more than 95 percent of families in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk. Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good stoves and other equipment to burn fuels in a more efficient way."There are already many technologies for clean fuels available now. An effective and reasonably low-cost ethanol stove that is made by Dometic (a Sweden-based company)is now being tested out. Another interesting development is electric induction stoves." In India, you can buy an... Question: Which would be the best title for the passage? Options: A: The way we cook is changing. B: Cause of indoor air pollution. C: The development of electric stoves. D: Indoor air pollution kills millions each year.
A: D

Q: Read the article and select the best answer. Article: These days everyone is worried about the size of their carbon footprint. In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2are we responsible for? A new book by Mike Berners Lee, an expert, might be able to help. The carbon footprint looks at the different things we do and buy, and calculates the amount of CO2all of the following created: the ingredients, the electricity, the equipment, the travel and commuting of the beer, and the packaging. It's amazing how many different things need to be included in each calculation. And it's frightening how much carbon dioxide everything produces. This can help us decide which beer to drink. From Berners Lee's calculations, it's clear that a pint (568ml) of locally _ beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away, and it uses more packaging. The local beer only produces 300g of CO2, but the imported beer produces 900g! So, one pint of local beer is better for the environment. Berners Lee has even calculated the carbon footprint of cycling to work. Nothing is more environmentally friendly than riding a bike, surely? Well, it depends on what you've had to eat before. To ride a bike we need energy and for energy we need food. So if we eat a banana and then ride a kilometer, our footprint is 65g of CO2. However, if we eat bacon before the ride, it's 200g. In fact, bananas are good because they don't need packaging, they can be transported by boat and they grow in natural sunlight. So, does this mean that cycling is bad for the environment? Absolutely not, for a start, if you cycle, you don't use your car, and the fewer cars on the road, the fewer traffic jams. And cars in traffic jams produce three times more CO2than cars traveling at speed. Cycling also makes you healthy and less likely to go to hospital. So maybe it's time for us all to start making some changes. Pass me a banana and a pint of local beer, please. Question: Which of the following is TRUE according to the passage? Options: A: Everything produces carbon dioxide equally. B: The imported beer is much better than the local beer in quality. C: Actually bananas are good in general because they produce less CO 2. D: To make our carbon footprints smaller, we should often drink more beer.
A: C
