Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially tree if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class.

Contrary to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.

The results of the test show that______.

A．breakfast has great effect on work and studies

B．breakfast has much to do with people's health

C．a person will work better if he has simple breakfast

D．breakfast only affects those who work with their brains

The preindustrial period of the development of cities in the United States

began with the establishment of the colonies in the late 1600's and lasted until

about 1850. During this period, urban residents made up a small percent of 【M1】______

the total population and cities were small on size. The leading cities were East 【M2】______

Coast seaports. The importance of water transportation in the preindustrial

period is reflected in building of many canals to expand the area in which trade 【M3】______

could be conducted. Water power was also the chief source. Most city

residents worked in commerce and trade, administration, service, the small-

scale hand production of goods. Mechanic production in the United Sates had 【M4】______

its beginnings only in the 1820s, when the first textile mills were set up in

New England using the spinning and weaving machines that had been invented

somehow earlier in England. Most people were farmers, but even city 【M5】______

residents were overwhelming rural in background and experience. The 【M6】______

internal structure of cities in the preindustrial period was relatively

differentiated into separate areas for separate activities, for they were small 【M7】______

enough such that people could easily work or ride, by horseback or by horse

and wagon, to the variation of available facilities. Thus, houses, shops, and 【M8】______

public buildings were typically interspersed; often the shopkeepers or artisans

lived above or behind their stores.

In the preindustrial cities in the United States, which we now regard as 【M9】______

municipal services did not exist. Generally, residents and businesses were

responsible for providing their own water supplies, disposal of sewage and

garbage, and health services. In a time, firefighting and police protection 【M10】______

were also provided on a volunteer basis.

【M1】

______ is put into use in the late years to maintain a preset tension in a mooring line after a ship has been tied up at a pier.

A.The large-tension mooring

B.The small-tension mooring

C.The variable-tension mooring

D.The constant-tension mooring

All that we really need to plot out the future of our universe are a few good measurements. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we do not know about the way the universe is put together. But we do know exactly what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it.

Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.

When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.

According to the passage, it is difficult to be certain about the distant future of the universe because we ______.

A．have too many conflicting theories

B．do not have enough funding to continue our research

C．are not sure how the universe is put together

D．have focused on investigations of the moon and planets

The historian Frederick J. Turner wrote in the 1890's that the agrarian discontent that had been developing steadily in the United States since about 1870 had been speeded by the closing of the internal frontier—that is, the depletion of available new land needed for further expansion of the American farming system. Not only was Turner's thesis influential at the time, it was later adopted and elaborated by other scholars, such as John D. Hicks in The populist Revolt (1931). Actually, however, new lands were taken up for farming in the United States throughout and beyond the nineteenth century. In the 1890's, when agrarian discontent had become most acute, 1,100,000 new farms were settled, which was 500,000 more than had been settled during the previous decade. After 1890, under the terms of the Homestead Act and its successors, more new land was taken up for fanning than had been taken up for this purpose in the United states up until that time. It is true that a high proportion of the newly fanned land was suitable only for grazing and dry farming, but agricultural practices had become sufficiently advanced to make it possible to increase the profitability of farming by utilizing even these relatively barren lands.

The emphasis given by both scholars and statesmen to the presumed disappearance of the American frontier helped to obscure the great importance of changes in the conditions and consequences of international trade that occurred during the second half of the nineteenth century. In 1869 the Suez Canal was opened and the first transcontinental railroad in the United States was completed. An extensive network of telegraph and telephone communications was spun: Europe was connected by submarine cable with the United States in 1866 and with South America in 1874. By about 1870 improvements in agricultural technology made possible the full exploitation of areas that were most suitable for extensive farming on a mechanized basis. Huge tracts of land were being settled and farmed in Argentina, Australia, Canada, and in the American West, and these areas were joined with one another and with the countries of Europe into an interdependent market system. As a consequence, agrarian depressions no longer were local or national in scope, and they struck several nations whose internal frontiers had not vanished or were not about to vanish. Between the early 1870's and the 1890's the mounting agrarian discontent in America paralleled the almost uninterrupted decline in the prices of American agricultural products on foreign markets. Those staple-growing farmers in the United States who exhibited the greatest discontent were who had become most dependent on foreign markets for the sale of their products. In so far as Americans had been deterred from taking up new land for farming, it was because market conditions had made this period a perilous time in which to do so.

The author provides information concerning newly farmed lands in the United States in paragraph 1 to support

A．a proposal by Frederick J. Turner that was later disputed by John D. Hicks.

B．an elaboration by John D. Hicks of thesis that formerly had been questioned by Turner.

C．the thesis that important changes occurred in the nature of international trade during the second half of the 19th century.

D．the view that the American frontier did not become closed during the 19th century or soon thereafter.
