阅读材料，回答问题。

材料一

农民在乡里造反，搅动了绅士们的酣梦……我初到长沙时，会到各方面的人，听到许多的街谈巷议。从中层以上社会至国民党右派，无不一言以蔽之曰：“糟得很。”……“糟得很”，明明是站在地主利益方面打击农民起来的理论，明明是地主阶级企图保存封建旧秩序，阻碍建设民主新秩序的理论……一切革命同志须知：国民革命需要一个大的农村变动。辛亥革命没有这个变动……现在有了这个变动，乃是革命完成的重要因素。

——《毛 * * 选集》第一卷

（1）材料一出自毛 * * 哪篇文章？毛 * * 批判了哪种错误态度？他对农民运动是如何认识的？（4分）

材料二

中 * * 党不是以空话，而是以领导农民进行土地改革的事实，使他们迅速看清是谁代表着他们的利益，应该跟着谁走。……中国革命的军事斗争同土地制度的改革是不能分开的……没有土地制度的改革，没有广大农民的全力支持，军事斗争也会失去力量源泉而不可能战胜强大的敌人。

——金冲及《二十世纪中国史纲》

（2）依据材料二，指出解放战争时期中 * * 党是怎样代表农民利益的？农民又是怎样“全力支持”解放战争的？（4分）

材料三

解放后农民对于个体经济的积极性是不可避免的。党充分地了解了农民这种小私有者的特点，并提出不能忽视和粗暴地挫折农民这种个体经济的积极性。

但是，党中央从来认为要克服很多农民在分散经营中所发生的困难，要使广大贫困的农民能够迅速地增加生产而走上丰衣足食的道路……就必须提倡“组织起来”，按照自愿和互利的原则，发展农民劳动互助的积极性。这种劳动互助……发展前途就是农业集体化或社会主义化。

——《中 * * 关于农业生产互助合作的决议（草案）》（1951年12月）

（4）综上，概括中 * * 党与农民的密切关系。（4分）

In these times when market forces appear increasingly complicated and more volatile, it is all the more important to understand the professional jargon and terminology in the market place in order to be able to better make our investment and business decisions. Understanding key economic indicators will assist in the decision making process, providing a snapshot of the current situation and an insight into the future.
(46) Each economic indicator tells us something about the economy or inflation. Gross Domestic Product (GDP) is probably the most important report as it is the whole framework where other economic indicators fall under.
There are also indicators that are broader tell us about the economy itself rather than the components, e. g. employment figures, leading indicators, money supply figures (M3). Inflation figures, Produce Price Index (PPI) and the Consumer Price Index (CPI) will, in short, inform us of the changes in wholesale prices, cost of consumer (retail) goods and services respectively.
An indicator that is useful must be accurate, timely and reliable. It depends entirely on the integrity of the national statistical system responsible. It is vital to know the accurate components of an indicator. We have to be mindful of the limitation of these statistical figures too.
Some indicators can be historic or extremely volatile, and therefore their values are reduced. It is better to compare the most recent data with earlier months, or take a moving average for the past 3, 6 or 12 months to smooth the data. It will tell us if there has been a significant change in trend and whether a new direction is under way.
Timeliness of an indicator is also significant. (47) Although the reported figures are important, it is crucial to recognize that markets react more to the variance to the consensus forecast than to the absolute change in the indicator. (48) Markets do not like surprises and can be frustrated with volatility upon subsequent revisions to the numbers published, even though significance of the absolute number diminishes with each passing month.
The Index of Leading Economic Indicators (L. E. I) in the US acts as an early warning system, telling us when the economy is about to change direction. (49) This composite index of 11 leading indicators has a good record of providing accurate forecasts. The total index performs better as a prediction tool than any of its parts. This monthly figure is available on the last business day of the month and has low volatility.
(50) As a general rule, turning points in the economy are signaled by three consecutive months of L. E. I changes in the same direction. This leading indicator is like a lighthouse, giving the rest of the world economies a glimpse of the direction of the’ world’s largest economy.
