In early pregnancy, certain changes occur in the mother's gastrointestinal tract, resulting in more efficient absorption of specific nutrients, such as iron and calcium. Furthermore, the maternal blood supply increases, so that nutrients can be transported via the uterine and placental blood systems: If the mother is undernourished, this "lifeline" to the fetus will be inadequately developed. Finally, fat is accumulated within the body to store the energy necessary for lactation (milk production), This preparation for lactation is so important that if the mother is inadequately nourished, it will take place even at the expense of fetal growth. It is a logical developmental occurrence, since in the natural world, no infant can survive without successful breastfeeding, and thus fetal growth is less of a priority.
According to the passage, which of the following is required for lactation？
A．Fat storage.
B．Iron and calcium.
C．Increased blood supply.
D．A well-nourished placenta.
A.To display current alarm of device correctly, the device needs to report current alarm to EMS actively. Therefore, necessary configuration for the device to actively report alarms must be correctly set.
B. Protection switching event alarm occurs at the instant when protection group switching happens, so it is not durative alarm. Therefore, after the alarm occurs, it is immediately saved in locking alarm. You can check it only in the locking alarms.
C. If EMS server timezone is different from PTN device timezone, alarm occurrence time on PTN device will be different from that on EMS. Therefore, during commissioning of PTN, you should set PTN timezone to be consistent with EMS timezone, usually local timezone.
D. None of the above

A．a person's living space needs

Examples of public goods are not as rare as one might expect.A flood control dam is a public good.Once the dam is built, all persons living in the area will benefit------irrespective of their own contribution to the construction cost of the dam.The same holds true for highway signs or aids to navigation.Once a lighthouse is built, no ship of any nationality can be effectively excluded from the utilization of the lighthouse for navigational purposes.National defense is another example.Even a person who voted against military expenditures or did not pay any taxes will benefit from the protection afforded.
It is no easy task to determine the social costs and social benefits associated with a public good.There is no practicable way of charging drivers for looking at highway signs, sailors for watching a lighthouse and citizens for the security provided to them through national defense.Because the market does not provide the necessary signals, economic analysis has to be substituted for the impersonal judgement of the marketplace.

A.difficult procedure
B.daily administrative duty
C.matter of personal judgement
D.citizen's responsibility
4.To find out the market for public goods, people need to （）.
A.watch out for the necessary market signals

Ironically, the first evidence for this idea appeared in the United States. Not long ago, with the country entering a recessing and Japan at its pre-bubble peak. The U.S. workforce was derided as poorly educated and one of primary cause of the poor U.S. economic performance. Japan was, and remains, the global leader in automotive-assembly productivity. Yet the research revealed that the U.S. factories of Honda Nissan, and Toyota achieved about 95 percent of the productivity of their Japanese countere pants a result of the training that U.S. workers received on the job.
More recently, while examing housing construction, the researchers discovered that illiterate, non-English- speaking Mexican workers in Houston, Texas, consistently met best-practice labor productivity standards despite the complexity of the building industry’s work.
What is the real relationship between education and economic development？ We have to suspect that continuing economic growth promotes the development of education even when governments don’t force it. After all, that’s how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn’t have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.
As education improved, humanity’s productivity potential, they could in turn afford more education. This increasingly high level of education is probably a necessary, but not a sufficient, condition for the complex political systems required by advanced economic performance. Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education. A lack of formal education, however, doesn’t constrain the ability of the developing world’s workforce to substantially improve productivity for the forested future. On the contrary, constraints on improving productivity explain why education isn’t developing more quickly there than it is.
31. The author holds in paragraph 1 that the important of education in poor countries ___________.
[A] is subject groundless doubts
[B] has fallen victim of bias
[C] is conventional downgraded
[D] has been overestimated
The relationship between formal education and e(‘onol11lc growth in poor countries is widely misunderstood by economists and politicians alike.Progress in both areas is undoubtedly necessary for the social, political and intellectual development of these and all other societies; however, the
conventional view that education should be one of the very highest priorities for promoting rapid economic development in poor countries is wrong. We are fortunate that is it. because new educational systems there an putting enough people through them to improve economic performance would require two or three generations. The findings of a research institution have consistently shown that workers in all countries can be trained on the job to achieve radical higher productivity and, as a result, radically higher standards of living.
