阅读以下关于嵌入式实时操作系统软件的选型分析方面的叙述，回答问题1至问题3。
某研究所承担了一项宇航嵌入式系统的研制任务，本项任务技术难度大、可靠性要求高、进度要求紧，预计软件规模约在一万行以上。而该所原先承担的相关项目均是用汇编语言编写的(软件规模较小，一般是几百行)。项目主管工程师将软件开发的论证工作分别布置给了王工和李工，要求他们根据本项目的技术要求，在一周内分别提出软件的实施方案。
(1)该宇航嵌入式系统由数据处理机、信号处理机以及数据采集模块组成。信号处理机主要通过数据采集模块将大量不同时间周期的外部数据采集进来，进行预处理(如 FFT变换)后提交给数据处理机；数据处理机根据功能要求完成各种计算处理工作，并将结果输出。为了达到数据处理机和信号处理机的标准化，这两类处理机均采用同种处理机的体系结构(如PowerPC7410)。整个系统工作的最大周期为1s，最小周期为5ms。数据处理机上任务分布如下表所示。
(2)一周后，王工和李工提交了各自的实施方案，其共同之处在于两者均提出采用操作系统及相应的软件开发环境。但是，王工和李工在选择什么样的操作系统及开发环境方面出现了较大的分歧。王工的实施方案提出，为了满足本项目的技术要求，并有利于本所软件的长期发展，应选用具有硬实时处理能力的嵌入式实时操作系统及开发环境 (例如VxWorks等)：而李工的实施方案指出，操作系统主要完成对计算机资源的管理与分配工作，考虑到人们对操作系统及软件开发工具的熟悉程度，本项目应选用具有大众化的、软件开发人员容易上手的嵌入式操作系统(例如WindowsCE、Linux等)。
(3)在两人争执不下的情况下，项目主管工程师组织了相关专家对王工和李工提交的实施方案进行了评审。最后，专家组一致认为王工的方案切实可行，操作系统的选型论证充分、客观，可以作为本所未来几年中相关项目的软件开发的基本环境。同时专家组还就具体实施选择嵌入式实时操作系统及开发环境产品时应着重考虑的相关问题提出了几点建议。
为什么专家组一致认为王工的实施方案切实可行？请用200字以内文字简要说明。

If policymakers hope to make faster progress in
improving economic performance, reducing poverty, and slowing 【M1】_____
population growth, they will have to go much farther in 【M2】_
their efforts to involve women in economic development.
Women really contribute more in economic terms than is 【M3】_
usually recognized. They account for over half the food
produced in developing world, even more in Africa; they 【M4】_
constitute one fourth of the developing world's industrial labor
force; they carry the main responsibility for childcare and
household chores; they head one fourth and more of the families 【M5】_
in many developing nations; and they usually fetch most of
the household's water and fuelwood.
Yet their contribution goes drastically underestimated,
partly because women's job often "does not count," and. partly 【M6】_
because much of it is home-based. Unpriced, it is hard to value,
and being often immediately consumed, it quickly ceases to be
visible. Studies in Nepal and the Philippines suggest that when
the production of rural women is valued properly, in average 【M7】_
they actually contribute about one half the family's income. 【M8】_
Women could contribute far more to their own welfare and
to the economy if their opportunities to do were not so confined. 【M9】_
The poor, male or female, suffer from limited access to
education and health care, information and technology, credit
and resources, even markets. But women also face additional
gender-related difficulties rooted in tradition—sometimes
codified into law and policy—and biology (the demands of
multiple pregnancies and the need to care for children). While
men normally go into the "outside" world, women often
lack in not only the chance to move "outside," but the resources 【M10】_____
to function at full effectiveness "inside"—at home.

SECTION B ENGLISH TO CHINESE
Directions: Translate the following text into Chinese.
Bingley was punctual to his appointment; and he and Mr. Bennet spent the morning together, as had been agreed on. The latter was much more agreeable than his companion expected. There was nothing of presumption or folly in Bingley that could provoke his ridicule, or disgust him into silence; and he was more communicative, and less eccentric, than the other bad ever seen him. Elizabeth, who had a letter to write, went into the breakfast room for that purpose soon after tea.
But on returning to the drawing room, when her letter was finished, she saw, to her infinite surprise, there was reason to fear that her mother had been too ingenious for her. On opening the door, she perceived her sister and Bingley standing together over the hearth, as if engaged in earnest conversation; and had this led to no suspicion, the faces of both, as they hastily turned round and moved away from each other, would have told it all. Their situation was awkward enough; but hers she thought was still worse. Not a syllable was uttered by either; and Elizabeth was on the point of going away again, when Bingley suddenly rose and, whispering a few words to her sister, ran out of the room.
Jane could have no reserves from Elizabeth, where confidence would give pleasure; and instantly embracing her, she acknowledged, with the liveliest emotion, that she was the happiest creature in the world.
