第4题：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. GrossDomestic 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 theConsumer Price IndexCPI) 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 LeadingEconomic 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.

The nobler and more perfect a thing is, the later and slower it is becoming mature.A、man reaches the mature{{U}} (1) {{/U}}of his reasoning powers and mental faculties{{U}} (2) {{/U}}before the age of twenty-eight; a woman at eighteen.And then, too, in the case of woman, it is the only reason of a sort--very mean in its{{U}} (3) {{/U}}. That is why women remain children their whole life long; never seeing{{U}} (4) {{/U}}but what is quite close to them,{{U}} (5) {{/U}}fast to the present moment, taking appearance for{{U}} (6) {{/U}}, and preferring{{U}} (7) {{/U}}to matters of the first importance. For it is{{U}} (8) {{/U}}his reasoning faculty that man does not live in the present only,{{U}} (9) {{/U}}the brute, but looks about him and considers the past and the future; and this is the origin of{{U}} (10) {{/U}}, as well as that of care and anxiety which so many people{{U}} (11) {{/U}}Both the advantages and the disadvantages, which this{{U}} (12) {{/U}}, are{{U}} (13) {{/U}}in by the woman to a smaller extent because of her weaker power of reasoning. She may, in fact, be described as intellectually shortsighted,{{U}} (14) {{/U}}, while she has an immediate understanding of what lies quite close to her, her field of{{U}} (15) {{/U}}is narrow and does not reach to what is{{U}} (16) {{/U}}; so that things which are absent, or past, or to come, have much less effect upon women than upon men. This is the reason why women are inclined to be{{U}} (17) {{/U}}and sometimes carry their desire to a{{U}} (18) {{/U}}that borders upon madness. In their hearts, women think it is men’s business to earn money and theirs to spend it--if possible during their husband’s life,{{U}} (19) {{/U}}, at any rate, after his death. The very fact that their husband hands them{{U}} (20) {{/U}}his earnings for purposes of housekeeping strengthens them in this belief.
