1. Three explanations for the negative slope are:
a. Interest rate effect
b. Real balance effect
c. Foreign purchases effect

Aggregate demand (AD) is a curve showing the total amount of goods and services (real GDP) that will be purchased at different price levels.

a. Interest rate effect:
As price level (P) rises, the real money supply (=nominal money supply/P) falls. This leads to an increase in interest rate. As interest rate rises, investment spending falls because of the increased cost of borrowing to finance investment. As investment falls, aggregate expenditure (AE) falls, in turn leading to a fall in real GDP (or Y). (Hence we see as P increases, Y decreases.)

Try picturing this in terms of the IS-LM model too. The fall in the real money supply, which leads to an increase in interest rate, causes the LM curve to shift leftwards. Along an unchanged downward sloping IS curve, this results in a fall in equilibrium real GDP because of an upward movement** along the IS curve (**we say upward movement because as interest rate rises, investment spending falls, AE falls and hence real GDP falls). This confirms our conclusion that a rise in P leads to a fall in real GDP.
NOTE: The interest rate effect is by far the dominant reason for a downward sloping AD curve.

b. Real balance effect (also known as real wealth effect or real money balances effect):
It operates through consumption. As price level rises, purchasing power of money balances falls. As our real wealth falls, we will cut back on our consumption spending; hence autonomous consumption (Co) falls. This results in a decrease in AE and hence a decrease in real GDP.

We can also picture this in terms of the IS-LM model. The fall in AE leading to a decrease in real GDP occurs at an assumed unchanged interest rate. This shifts the IS curve leftwards from IS(0) to IS(1). With an unchanged upward sloping LM curve, the fall in real GDP lowers transactions demand for money and hence total money demand (which comprises both transactions demand and asset demand components). This in turn lowers interest rate (that is, a downward movement along the LM curve). As interest rate falls, we know that investment spending will rise and hence AE and real GDP will rise (that is, a downward movement along IS(1)). [Of course, this rise in real GDP is not enough to offset the original fall in real GDP because to the downward sloping nature of the LM curve.] This ensures attainment towards simultaneous equilibrium in money market and output market. Overall, we trace that a rise in P leads to a fall in Co, AE, and hence Y.

c. Foreign purchases effect:
It is applicable only to open economies with foreign trade being introduced into our explanation. With an increase in domestic price level relative to those of trading partners, domestic consumers will spend less on domestically produced goods and services and more on imports (M). Also, foreigners will buy less of our exports (X). The increase in M and decrease in X (that is, a decrease in net exports) means a decrease in real GDP.

In terms of our IS-LM model, the decrease in net exports causes a fall in AE, a fall in real GDP and hence a leftward shift in the IS curve. With an unchanged LM curve, we notice an overall fall in both interest rate and real GDP (as we have explained in our "real balance effect"). It is conclusive that a rise in P leads to a fall in Y.

2. The sticky-wage model of the upward sloping short run aggregate supply curve is based on the labor market. In many industries, short run wages are set by contracts. That is, workers are paid based on relatively permanent pay schedules that are decided upon by management or unions or both. When the economy changes, the wage the workers receive cannot adjust immediately.

Given that wages are sticky, the chain of events leading from an increase in the price level to an increase in output is fairly straightforward. When the price level rises, the nominal wage remains fixed because this is solely based on the dollar amount of the wage. The real wage, on the other hand, falls because this is based on the purchasing power of the wage. A higher price level means that a given wage is able to purchase fewer goods and services.

PARAGAPH When the real wage that firms pay employees falls, labor becomes cheaper. However, since the amount of output produced for each unit of labor is still the same, firms choose to hire more workers and increase revenues and profits. When firms hire more labor, output increases. Thus, when the price level rises, output increases because of sticky wages.

Let's summarize the chain of events that leads from an increase in the price level to an increase in output in the sticky-wage model. When the price level rises, real wages fall. When real wages fall, labor becomes cheaper. When labor becomes cheaper, firms hire more labor. When firms hire more labor, output increases.

3. The worker-misperception model of the upward sloping short- run aggregate supply curve is again based on the labor market. This time, unlike in the sticky-wage model, wages are free to move as the economy changes. The amount of work that an employee is willing to supply is based on the expected real wage. That is, workers know how many dollars they are being paid, the nominal wage, but workers can only guess at how much goods and services they can purchase with this wage, the real wage. In general, the higher the real wage, the more work that workers are willing to supply.

Now let's say that the price level increases. Because we assume that firms have more information than workers do, firms will give workers a raise so that their nominal wage increases with the price level. But since the workers do not realize that the price level increased, they will believe that their real wage increased, not just their nominal wage. At a higher real wage, workers are induced to work more. When workers work more, output increases. Thus, when the price level increases, output also increases because of worker-misperception.

Let's summarize the chain of events that leads from an increase in the price level to an increase in output in the worker-misperception model. When the price level rises, firms increase nominal wages. When nominal wages increase, workers--due to misperceptions--believe that real wages also increase. When workers believe that real wages increase, workers provide more labor. When workers provide more labor, output increases.

这几个答案写的挺不错的而且解释的很详细,是网上就能找得到的答案,因为写的很详细解释的也很清楚就没有自己写给你.但是如果这是大学的assignment作业题的话,建议读一下这个答案然后明白了之后用自己的话写一遍,因为很有可能许多人都搜这个,被抓到就shi了.如果需要相关资料的话,每个答案底下有我找到这个答案的网址,可以点进去再细看.尤其是后面这个,他对总供给曲线为什么slope是上行的几种模式解释的挺全.

即使那样,市场需求也左右着所需产品的形式.
Even then(插入语),
the market demand dictates the type of products(主句,主、谓、宾)
that are needed.(定语从句,修饰产品).

对新房的需求所引发的主要效果就是使价格膨胀.

题目是供求的方程分别为S=..D=...
要求供求平衡,就是S=D,得出P=300
当为平衡价格时,需求量是D=-4/3P+500=100

1)用950-800=150,再用150除于标准差75,得到2,查正态分布表得临界值2对应的概率大约为5%,所以提供950份以上的概率是5%
2）800-650=150,因为正态分布是对称的,所以提供650份以下的概率是5%,650份到950份之间的概率为90%
3）查正态分布表,得出1%时的临界值,用其乘以标准差得出一个数,再用800减去这个数就是结果
4）应该是一个联合分布的问题吧,题意理解不清,sorry.

最好不要,need意思是必需,no need意思没有必要,而demand指需求,一般是指市场需求,与供应对应,no demand意思没有需求.在这个语境下还是用need更为准确~

在更科学的教育要求中隐含着一个主张,即,如果一个人在科学方面接受过培训,与没有接受过这种培训的人相比,他会用更聪明的方法来对待所有学科.

Demand for a product is the amount of need for a particular item by consumers and suppliers.

demand to do sth.要求做某事
demand sth.from/ of sb.向某人要求某物
demand （that） sb.(should) do sth.要求某人做某事
注意：should 省略后面还是do sth.动词原形
你写的两个短语都是错误的,一旦demand 后面出现 sb.,那么sb.必定是从句的主语,此从句用虚拟语气.
祝学习愉快!

Demand 只能用demand for sth 或者demand of sth,也就是说是需要某物,还可以加宾语从句,楼主说的意思可以这样表示,demand that sb does something,.这样接的一定是宾语,或宾语从句.但是不可以接不定式to do sth.

要求某人做某事
例：
demanded him to speak to the manager.
要求他同管理者说话

会议要求大家准时到场
非要用demand of的话：
We are demanded of complete punctuality to the meeting.
其他：
Your punctual presence is required.
Everybody is requeired to attend the meeting on time.

不知你知不知道有这样的用法
suggest that +sb.(should) do sth.
e.g.She suggest that he close the window.
在这里,close要用原形.这是suggest的虚拟语气用法.
这里的be allowed用be原形也应是这个虚拟语气原理.
希望对你有所帮助!

For Example:
1)、I demand to do the marketing work this year.(我要求今年去做营销工作）
2)、All of us demand of him whether he had heard from her recently.(我们大家都问他最近是否收到了她的来信）
I hope you could understand easily from the above two examples.

这个和斜率没有关系,任何斜率的弹性曲线,在不同部位的elasticity值是不一样的.为什么呢?
100到99的变动是1,是一个单元,10-9的变动也是1,也是一个单元,但是100在变成99的时候,它的值只改动了1%,而10变成9的时候,却减少了10%.
在demand curve的左方,靠近零(或者Y轴)的地方,Y的值是很高的,而X的值离零很近(因为在左面嘛,这个理解应该没问题吧?) 越是往右边,Y的值越是小,而X的值越是大.
这样的话,在左面,可能X=9,Y=100,当X向又移动了1个单元以后,X增加了1/9,也就是11%,而Y呢,只减少了1%,变成99了,虽然在Y轴上对应的Y的值也只移动了一个单元.
那么这个时候的elasticity 就是1%/11%,等于0.9.(换句话说,X向右移动一格,Y向下移动一格,但是变化的比率是不同的)
同样道理,在右边,可能X从99增加到100,只增加了1/99,也就是1%左右,但是这个时候Y的值可能减少了10%.(从10到9,减了10%).这个时候,虽然是在同一根线上,这个点移动的elasticiy是10%/1%=10.
同样一根线,X在左面移动一个单元和在右面移动一个单元,造成的效果是不一样的.所以说,一根elasticity curve of demand的值是不断改变的.

楼上翻译蛮好的,我也凑个热闹：
不是本能的需求,而是心灵的召唤

demand for electricity in winter,much higher taht of summer,varies between 45000 at 9pm and 3000 units at 6 am
主语是demand for electricity in winter
定语是much higher that of summer,相当于which is much higher that of summer
谓语是varies
后面的between 45000 at 9pm and 3000 units at 6 am应该是状语,修饰前面的varies,表示是从……到……这个区间变化
具体是什么状语不是很肯定,不知道算不算是方式状语.

“如果需求与供给曲线都向右偏,则我们可以推断出总量变化方向,但是无法断定价格变化方向.如果供给曲线向右偏、需求曲线向左偏,则我们无法断定总量变化方向以及价格变化方向.”
对于以上文字,你是否同意?并叙述同意/不同意的理由.

商品的价格下降将导致其需求增加,这是一般性条件,即对几乎所有的商品都是如此.
然后推到特殊,即“某个”特定的商品,
因为该商品的价格下滑了 ,所以该商品的需求将会增加.

这句话完整的表达应该是
students demand that the library（should） be open at weekends
demand后面的宾语从句要用虚拟语气.即：demand that sb.(should) do的形式
should可是省略

译文：对有机食品的需求正在以每年大约三分之一增加.
every year现在时态,进行时强调正在增加.
increase by增加了……
increase to增加到……
reduce by减少了……
reduce to减少到……
His income has increased by 30 percent.他的收入增加了三成.
His income has incresed to 3300 yuan a month.他的收入增加到了每月3300元.

意思是：不需要排除总需求量的作用或环境监管的作用.

个人认为,被动语态应该有及物动词啊,可we are in need of experts不符合被动语态条件,所以不要混淆.楼上说得对,demand就是个名词

1. requires 2. demanded 3. request 4. effect 5. influence6. effect
