A rapid means of long-distance transportation became a necessity for the United States as

settlement (新拓居地) spread ever farther westward. The early trains were impractical curiosities, and for a long time the railroad companies met with troublesome mechanical problems. The most serious ones were the construction of rails able to bear the load, and the development of a safe, effective stopping system. Once these were solved, the railroad was established as the best means of land transportation. By 1860 there were thousands of miles of railroads crossing the eastern mountain ranges and reaching westward to the Mississippi. There were also regional southern and western lines.

The high point in railroad building came with the construction of the first transcontinental system. In 1862 Congress authorized two western railroad companies to build lines from Nebraska westward and from California eastward to a meeting point, so as to complete a transcontinental crossing linking the Atlantic seaboard with the Pacific. The Government helped the railroads generously with money and land. Actual work on this project began four years later. The Central Pacific Company, starting from California, used Chinese labor, while the Union Pacific employed crews of Irish laborers. The two groups worked at remarkable speed, each trying to cover a greater distance than the other. In 1869 they met at a place called Promontory in what is now the state of Utah. Many visitors came there for the great occasion. There were joyous celebrations all over the country, with parades and the ringing of church bells to honor the great achievement.

The railroad was very important in encouraging westward movement. It also helped build up industry and farming by moving raw materials and by distributing products rapidly to distant markets. In linking towns and people to One another it helped unify the United States.

The major problems with America's railroad system in the mid 19th century lay in ______.

A.poor quality rails and unreliable stopping systems

B.lack of financial support for development

C.limited railroad lines

D.lack of a transcontinental railroad

Historians of womens labor in the United States at first largely disregarded the story of female. service workers—women earning wages in occupations such as salesclerk. domestie servant ,and office secretary. These historians focused instead on factory work ,primarily becouse it seemed so different from traditional. unpaid "women&39;s work". in the home.and because the underlying economie forces of industrialism were presumed to be gender blind and hence emancipatory(解放的) in efect. Unfortunately. emancipation has been less profound than expected,for not even industrial wage labor has escaped continued sex segregation(隔离) in the workplace. To explain this unfinished tevolution in the status of women. Historiens have recently begun to emphasize the way a prevailing definition of femininity often determines the kinds of work allocated to women.even when such allocation is inappropriate to new conditions.For instance.early textile-mill entrepreneurs,in justilying women&39;s employment in wage labor. made much of the assumption that women were by nature skillful at detailed tasks and patient in carrying out repetitive chores; the mill owners thus imported into the new industrial order hoary stereotypes associated with the homemaking activities they presumed to have been the purview of women. Because women accepted the more unattractive new industrial tasks more readily than did men. such jobs came to be regarded as female jobs.And employers. who assumed that women&39;s "real" aspirations were for marriage and family life.declined to pay women. wages commensurate with those of imen. Thus many lower-skilled , lower-paid.less secute jobs came to be perceived as "female".

Job segregation by sex in the United States was____.

A.justified by early textile mill owners

B.one means’for women to achieve greater job security

C.reluctantly challenged by employers

D.a constant source of labor unrest in the young textile industry

Historians of womens labor focused on factory work as a more promising area of research than service-sector work because factory work_____.A.involved the payment of higher wages

B.required skill in detailed tasks

C.was assumed to be less characterized by sex segregation

D.was more readily accepted by women than by men

It can be inferred trom the passage that early historians of women’s labor in the United States paid little attention to womens employment in the service sector of the economy because______ .A.fewer women found employment in the service sector than in factory work

B.the wages paid to workers in the service sector were much lower than those paid in the industrial sector.

C.womens employment in the service sector tended to be much more short-term than in factory work

D.employment in the service sector seemed to have much in common with the unpaid work associated with homemaking

The early mill owners____.A.hoped that by creating relatively unattractive female jobs they would discourage women from losing interest in marriage and family life

B.sought to keep womens wages low by intereasing the size of the available labor force

C.argued that women were inherently suited to do well in particular kinds of factory work

D.thought that factory work bettered the condition of women by emancipating them from dependence on income earned by men.

第9题
How men first learned to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other, and later they agreed on certain signs. These signs were called letters, which could be combined to represent those sounds and could be written down. Those sounds, whether spoken or written in letters, are called words.

The power of words, then, exists in their associations—the things they bring up before our minds. Words become filled with meaning for us by experience, and the longer we live, the more certain words remind us of the glad and sad events of our past, and the more we read and learn, the more number of words increases.

Great writers are those who not only have great thoughts but also express these thoughts in words which deeply attract our minds and emotions. This skillful use of words is called "literary style". Above all, a real poet can express his meaning in words which sing like music and can move men to tears. We should, therefore, learn to choose our words carefully and use them properly, or they will make our speech silly and vulgar.

The origin of language is______.

A.treasure handed down from the past

B.a matter that is hidden or secret

C.a problem not yet solved

D.a question difficult to answer
