A、
This displacement formula still work.
B、The primary structure set up for the calculation of desired displacement should be the same one that has been used to determine internal forces in the original structure.
C、The primary structure set up for the calculation of desired displacement don't need to be the same one that has been used to determine internal forces in the original structure.
D、We can choose any primary structure for the original structure to calculate the desired displacement because all primary structures have the same internal forces and displacement with the original structure's.
For this reason, the international community has committed itself to getting all the world's children into primary school by 2015, a commitment known as Education for All.
Can education for all be achieved by 2015？ The answer is definitely "yes", although it is a difficult task. If we now measure the goal in terms of children successfully completing a minimum of five years of primary school, instead of just enrolling for classes, which used to be the measuring stick for education, then the challenge becomes even more difficult. Only 32 countries were formerly believed to be at risk of not achieving education for all on the basis of enrollment rates. The number rises to 88 if completion rates are used as the criterion.
Still, the goal is achievable with the right policies and the right support from the international community. 59 of the 88 countries at risk can reach universal primary completion by 2015 if they bring the efficiency and quality of their education systems into line with standards observed in higher-performing systems. They also need significant increases in external financing and technical support. The 29 countries lagging farthest behind will not reach the goal without unprecedented rates of progress. But this is attainable with creative solution, including use of information technologies, flexible and targeted foreign aid, and fewer people living in poverty.
A key lesson of experience about what makes development effective is that a country's capacity to use aid well depends heavily on its policies, institutions and management. Where a country scores well on these criteria, foreign assistance can be highly effective.
In the first paragraph, the author suggests that a quality education can ______
A．free countries from foreign rules
B．speed up social progress
C．give people freedom
D．liberate people from any exploitation

Many of the problems we face today are not so new as we think they are. And some of our modern solutions are not so new， either. The problem of energy shortages and the solution of using solar energy go back at least to early Greek cultures. The climate in the coastal areas of Greece 2，500 years ago was characterized by cool winters， much as it is today. At that time， the Greeks heated their homes with small， charcoal-burning heaters. In other words， wood （which is used to make charcoal） was their primary source of energy.However， by the fifth century BC fuel shortages had become common because， in many parts of Greece， the firewood in the forests had been depleted. Once the supply of firewood from the local forests ran out， people began to use the wood from olive groves as fuel. But this solution had its own problem. It reduced the olive crop， a valuable resource to the Greeks. By the fourth century BC， the city of Athens banned the use of olive wood for fuel. Wood had to be imported from farther and farther away， making it more difficult to obtain and more expensive to use. About this time the Greeks began to build their houses facing south， so that the low sun in winter could penetrate and help heat the interiors. Excavations of ancient Greek cities suggest that large areas were planned so that individual homes could take maximum advantage of passive solar energy.

While the emergence and persistence of ethnic niches testify to the
pervasive effects of social structures, the growing educational level of African
Americans since the 1970s has also equipped them for jobs that immigrants
Line found hard to obtain. The proportion of African Americans workers whose
(5) limited schooling confines them to such jobs as apparel manufacturing or
domestic work has declined. In particular, African Americans have found a
niche in the public sector, a shift that may have diminished the effects of
immigrant competition and put them in a position to absorb the positive effects
associated with the population gains produced by immigration. Without formal
(10) educational credentials, it is difficult for the least-skilled African Americans to
exploit the ethnic networks implanted in government employment, and thus
they must find employment in an immigrant saturated market. As the public
sector is now a declining enterprise, and more and more immigrants seek access
to public-sector jobs, only alternative deserving of attention is the creation of
(15) more private-sector employment for African Americans with limited schooling.
The primary purpose of the passage is to
A．analyze a current trend in relation to the past
B．discuss a particular solution to a long-standing problem
C．analyze changes in the way a long-standing problem is viewed
D．apply a generalization to an unusual situation
E．describe an old approach by contrasting it with a newer approach
The words used to describe women are used as an instrument by feminist sociolinguists to denote an inherent sexism in the English language. Word pairs such as master and mistress and sir and madam, they claim, epitomize such sexism. All of the words in question once held positive connotations but, while the masculine forms have retained their respectable associations, the feminine forms have undergone pejoration and now imply sexual promiscuity and other negative characteristics. Feminist researchers assume that such pejoration indicate that the status of women in English-speaking society is relatively low.
These researchers also find fault with the use of masculine words to describe unisex entities. For example, they feel that there is nothing inherently manly about mankind, the best man for the job, or the common man. Similarly, the use of such constructions as the "the average student is worried about his grades" indicate to these researchers an inherent sexism in English that is reflective of the cultures in which they are produced.
Carolyn Jacobson, author of Non-sexist Language has proposed a solution to this conundrum. She advocates the elimination of all sexed words in favor of gender-neutral terms. No longer should we refer to actors and actresses or waiters and waitresses, as such dichotomies allow for the possibility of negative connotations being associated with the feminine designation. Likewise, she believes that phrases such as mankind should give way to human kind and that the use of the masculine pronoun as the default should be abandoned in favor of neutral constructions. Thus, when sexism is eliminated from the English language, the culture will be more amenable to the deliverance of women as well.
The primary purpose of this passage is to ______.
A．compare and contrast ideology in various cultures
B．prove a commonly held belief to be wrong
C．describe a problem and a possible solution
D．analyze the historical origins of a modern situation
