答案

小题1:B

小题2:C

小题3:B

小题4:A

小题1:本题考查水循环。水循环可分为海陆间循环、海上内循环、陆上内循环。水循环的主要环节有:蒸发、降水、水汽输送、地表径流、下渗、地下径流、植物蒸腾等。图中A为陆地,B为海洋,①为径流,③为水汽输送,④为降水。把太阳能转化为水体势能的主要是②蒸发;塑造各种地表形态的主要是①径流。所以本题选择B选项。

小题2:此图为中纬大气环流,S线为地表,S为正南方向。图中A为30°附近动力原因形成的副热带高压;B地纬度高,气温低,对流层高度低;A地气温高,蒸发量大;AB之间为南半球的西风带,为西北风。所以本题选择C选项。

小题3:本题考查地壳物质循环:地球内部的岩浆,经过冷却凝固形成岩浆岩,岩浆岩受流水、风、冰川、海浪等的侵蚀、搬运、堆积作用,形成沉积岩。同时,这些已生成的岩石,在一定温度和压力等作用下发生变质,形成变质岩。各类岩石在地壳深处或地壳以下发生重熔再生作用,又成为新的岩浆。从岩浆形成各类岩石,再到新岩浆的过程,就是地壳内部的物质循环。B为岩浆,则②为冷却凝固形成岩浆岩C;AD岩石无法固定。所以本题选择B选项。

小题4:本题考查洋流的分布规律。洋流分布规律:①中低纬度海区形成以副热带高压为中心的大洋环流,北顺南逆;②北半球中高纬度海区形成以副极地低压为中心的逆时针大洋环流;③南纬40°附近海域形成环球性西风漂流。④北印度洋海区形成季风环流,夏顺冬逆。则该洋流位于南半球的副热带海区,④为暖流,使沿岸增温增湿。所以本题选择A选项。

填空题

Perhaps, every county suffered from inflation once or more times. Inflation is an economic condition in (B1) prices for consumer goods (B2) , and the (B3) of money or purchasing power decreases. There are three causes of inflation. The first and most important cause may be excessive government spending. For example, in order to (B4) a war or carry (B5) social programs, the government may spend more money than it has received through taxes and other revenues, thus creating a deficit. In order to (B6) this deficit, the Treasury Department can simply (B7) the money supply by issuing more paper money to (B8) the debts of government. This increase in the money supply will cause the value of the dollar to (B9) decrease. The second cause of inflation occurs when the money supply increases faster than the supply of goods. (B10) people have more money, they will run out to buy popular goods (B11) televisions and computers, for example, and a shortage will result. Industry will then produce more, at higher prices, to (B12) demand. (B13) , if people think that the prices of popular goods are going up, they will buy and even borrow money at high (B14) rates to pay for them. Finally, if labor unions demand that workers’ wages (B15) or (B16) the high cost of living, industry will meet this demand and add other costs of production on the (B17) . (B18) summary, all of these causes can (B19) inflationary problems that can affect the welfare of a nation. However, of these three causes, (B20) government spending may be the most important.

A.finance

B.offer

C.pay

D.fight
