边界就会成为直角形状，两种产品的产出也不取决于它们的相对价格。在这种情况下，贸易条件的改善是否会提高一国的福利水平？请画图进行分析。

In some economies relative supply may be unresponsive to changes in prices．For example，if factors of：production were completely immobile between sectors，the production possibility frontier would be right-angled，and output of the two goods would not depend on their relative prices．Is it still true in this case that a rise in the terms of trade increases welfare？ Analyze graphically．

There are approximately three quarters of a ton of termites (白蚁) for every person on Earth. It now turns out that these critters may be helping to alter the climate and affect man's life.

For years scientists have been saying that carbon dioxide sent into the atmosphere by the burning of fuels might lead to the rise in temperatures of the whole earth, owing to the greenhouse effect in which the gas prevents the escape of heat into outer space. Now an international team of researchers has discovered that termites generate more than twice the carbon dioxide that fuel burning does. And this production, which comes from the insects' eating and consuming of different kinds of vegetables and wood, has risen greatly. This is chiefly because man has cut so many trees in order to open more land and thus has provided large quantities of food for the insects in the form. of tiny pieces of wood.

The output from the burning of fuels is of greater concern, however, because it is continuing to rise steadily and so far no effective measures have been taken to reduce the amount of carbon elements in this way. Production by termites, on the other hand, is not likely to increase much more.

From the passage we know that" the greenhouse effect" is an effect in which ______ .

A．low temperatures are created by using a house

B．the house is made green in order to keep heat

C．heat is prevented from escaping outside

D．everything is kept green in a house

假设利率平价并不完全成立，而真实的关系是R=R^*+(E^e-E)/E+ρ，其中，ρ衡量的是国内储蓄与国外储蓄之间的风险差异。假设政府开支出现永久性的增加。由于可能导致的政府赤字，ρ也增大了，即本币存款的风险变大。请分析一下在此情况下这一政策对产出的影响。

Suppose that interest parity does not hold exactly，but that the true relationship is R=R^*+(E^e-E)/E+ρ where ρ is a term measuring the differential riskiness of domestic versus foreign deposits．Suppose a permanent rise in domestic government spending，by creating the prospect of future government deficits，also raises ρ，that is，makes domestic currency deposits more risky．Evaluate the policy's output effects in this situation．

么中央银行也就放弃了它运用货币政策来控制工资一价格螺旋式上升的能力。这种说法通常这样表述：“假设工人要求更高的工资而雇主同意的话。那么雇主就会提高其产品价格以弥补更高的工资成本。因为价格水平的提高会导致实际均衡点立即下降。为了防止利率的上升可能引发的本币升值，中央银行必须购进外国货币，因而增加了货币供给。中央银行的这种行动是通过增加货币供给来满足最初的增加工资的要求，使经济永久性地向更高的工资与价格水平移动。实行固定汇率是无法使工资与价格下降的”。这种说法错在哪里？

A central bank that adopts a fixed exchange rate may sacrifice its autonomy in setting domestic monetary policy．It is sometimes argued that when this is the case，the central hank also gives up the ability to use monetary policy to combat the wage-price spiral．The argument goes like this：“Suppose workers demand higher wages and employers give in，but that the employers then raise output prices to cover their higher costs．Now the price level is higher and real balances are momentarily lower，so to prevent an interest rate rise that would appreciate the currency，the central bank must buy foreign exchange and expand the money supply．This action accommodates the initial wage demands with monetary growth and the economy moves permanently to a higher level of wages and prices．With a fixed exchange rate there is thus no way of keeping wages and prices down.” What is wrong with this argument？
