     It is a matter of common observation that although money income keeps going up over the

years, we never seem to become richer. Prices are rising continuously. This condition is what

we call inflation (通胀) the money supply is becoming inflated so that each unit of it becomes

less valuable. We have got used to higher and higher rates of inflation in recent years. What

could be bought twenty years ago for one pound now costs well over 2 pounds. And at present

this rate of inflation seems to be rising rather than falling. If in the real world our money incomes

go up at the same rate as prices do?One might think that inflation doesn't matter. But it does .

     When money is losing value it also loses one of the qualities of a good money-stability(稳定)

of value. It is no longer acceptable as a store of value; and it becomes an unsuitable means

of delayed payment. Nobody wants to hold a wasting possession, so people try to get rid

of money as quickly as possible. Inflation therefore simply simulates(刺激)our spending and

discourages saving.

1.From the passage we can know that inflation is a situation in which________.

A. everyone's incomes rise

D. money constantly loses its value

2.In the writer's view, if incomes and prices rise at the same rate, ________.

A. inflation maybe still be a problem

数码相机一旦进水,无论是溅入液体还是整机进水,都应立即切断电源,以防电路烧毁。如果相机在关机状态下,需要做的第一件事情就是卸掉电池。如果相机溅入的是淡水,通常专家会建议把相机放在台灯、射灯等轻微热源下让水分慢慢散去,或将相机在干燥通风的地方放置至少一天,然后通电进行功能检查。若出现异常情况应立即切断电源,切勿心急使用电吹风等强热源直接靠近相机,这会导致线路严重老化,甚至外壳、电路板变形。如果相机遭遇海水、饮料或整机进水,应立即送维修站进行处理。因为海水及饮料对相机的电路板、机内的金属零件有强烈的腐蚀性,如不及时处理有可能会造成相机的报废。
进水的相机经过维修后,由于进入到相机芯片以及电路板金属孔里的液体无法清除,如果受潮将会继续产生锈蚀现象,所以进过水的相机在保存、使用时务必注意防潮。

进海水若不及时处理会致使相机报废的原因是:

A.电路板被破坏

B.机内金属受损

C.腐蚀机内零件

D.线路严重老化
