Ques: Read the article and select the best answer. Article: Scientific Progress Most scientific progress is the result of careful consideration of work that has already been done. The wonderful world which lies before us today has been put up by hardworking men with clear heads and inventive mind, and these who follow them along life's road will improve on their efforts. It is sometimes necessary to question and even to disbelieve some of the statements made by experts. Action or experiment can often end an argument or achieve a breakthrough. When men were wondering whether it was possible to reach India by sailing westwards from Europe, and whether there was any land on the other side of the Atlantic Ocean, Christopher Columbus decides to act. He gathered some men, invited them to go on board his three ships, and set out across the dangerous waters of the Atlantic Ocean. He was successful in finding land, but it was not India. The result of his action was that the arguments came to the end. Any young man who wishes to do research must be courageous enough to question old beliefs and do some original thinking about them. Although we seem to know so much, there are many things we don't know. Even when we pull an atom to pieces, we do not really know what the pieces are, we often do not reach the reality behind what we discover, and the more we learn, the better we realize our ignorance. Question: According to the passage, the more we learn _ Options: A: the more ignorance we will become B: the more brilliant we are C: the more confident we are of ourselves D: the more we know about our ignorance
Ans: D

Ques: Read the article and select the best answer. Article: Boiler rooms are often dirty and steamy,but this one is clean and cool.Fox Point is a very new 47unit living building in South Bronx,one of the city's poorest areas.Twothirds of the people living there are formerly homeless people,whose rent is paid by the government.The rest are lowincome families.The boiler room has special equipment,which produces energy for electricity and heat.It reuses heat that would otherwise be lost to the air,reducing carbon emissions while also cutting costs. Fox Point is operated by Palladia,a group that specializes in providing housing and services to needy people.Palladia received support from Enterprise Community Partners (ECP),which helps build affordable housing by providing support to housing developers. ECP has created national standards for healthy,environmentally clever and affordable homes which are called the Green Communities Standards.These standards include water keeping,energy saving and the use of environmentally friendly building materials.Meeting the standards increases housing construction costs by 2%,which is rapidly paid back by lower running costs.Even the positioning of a window to get most daylight can help save energy. Michael Bloomberg,New York's mayor,plans to create 165,000 affordable housing units for 500,000 New Yorkers.Almost 80% of New York City's greenhouse gas emissions come from buildings,and 40% of those are caused by housing.So he recently announced that the city's Department of Housing and Preservation and Development (DHPD),whose duty is to develop and keep the city's supply of affordable housing,will require all its new projects to follow ECP's green standards. Similar measures have been taken by other cities,such as Cleveland and Denver,but New York's DHPD is the largest city developer of affordable housing in the country.(2010*,B) Question: What is the main purpose of this text? Options: A: To call on people to pay more attention to housing problems. B: To prove that some standards are needed for affordable housing. C: To ask society to help homeless people and lowincome families. D: To introduce healthy,environmentally clever and affordable housing.
Ans: D

Ques: Read the article and select the best answer. Article: A new study gives us the warning that about thirty percent of the world's people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East. P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same. Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase. The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning. The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture. The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow... Question: It can be inferred that _ . Options: A: There is connection between providing clean water and slowing population growth B: Lack of water may also result from international conflict C: The ability of developing has nothing to do with lack of water. D: It is not known whether diseases have something to do with lack of water
Ans: A

Ques: Read the article and select the best answer. Article: For the most part, it seems, workers in rich countries have little to fear from globalization, and a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich-country counterparts to benefit, because they have less to lose and more to gain. Traditional economics takes an optimistic line on integration and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labour have already been used up. If poor countries lower their barriers to trade and investment, the theory goes, rich foreigners will want to send over some of their capital. If this inflow of resources arrives in the form of loans or portfolio investment , it will top up domestic savings and loosen the financial restriction on additional investment by local companies. If it arrives in the form of new foreign-controlled operations, FDI, so much the better: this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investment ought to push incomes up, partly by raising the demand for labour and partly by making labour more productive. This is why workers in FDI-receiving countries should be in an even better position to profit from integration than workers in FDI-sending countries. Also, with or without inflows of foreign capital, the same gains from trade should apply in developing countries as in rich ones. This gains from trade logic often arouses suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets through trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory,... Question: Why are workers in poor countries more likely to benefit from the process of globalization? Options: A: They can get more chances to gain a good job. B: They can get more financial aid. C: They have nothing to lose. D: They have less to lose and more to gain.
