二：

[00:01.18]Directions: In this section,

[00:03.96]you will hear a passage three times.

[00:05.79]When the passage is read for the first time,

[00:07.94]you should listen carefully for its general idea.

[00:10.91]When the passage is read for the second time,

[00:14.65]you are required to fill in the blanks

[00:16.95]with the exact words you have just heard.

[00:19.07]Finally, when the passage is read for the third time,

[00:22.96]you should check what you have written.

[00:25.23]Now listen to the passage.

[00:28.92]Many college students today own personal computers

[00:31.98]that cost anywhere from ¡ç1 000 to perhaps ¡ç5 000 or more.

[00:37.31]In addition, it is not uncommon for them

[00:40.98]to purchase software costing another several hundred dollars.

[00:44.53]Twenty years ago, computers were available,

[00:48.03]but they were very large and extremely expensive.

[00:50.44]Few, if any, individuals purchased computers for home use.

[00:55.12]Over the years the price of the ¡°guts¡± of a computer

[00:59.95]¡ªits memory¡ªhas declined to less than

[01:03.11]a thousandth of the price per unit of memory

[01:05.47]that prevailed twenty years ago.

[01:07.33]This is the main reason why computers cost

[01:10.43]so much less today than they used to.

[01:13.66]Moreover, technological improvements have made it possible

[01:17.86]to manufacture memory circuitry

[01:20.22]that is small enough to fit into the portable personal computers

[01:23.80]that many of us own and use.

[01:26.75]In short , as the price of computation

[01:30.07]has declined the average consumer and business

[01:33.27]have spent more on purchasing computers.

[01:35.83]By contrast, improved agricultural technology,

[01:40.98]hybrid seeds, scientific animal breeding,

[01:44.35]and so on have vastly increased

[01:47.46]the amount of output a typical farmer can produce.

[01:50.39]The prices of goods such as meats and grains

[01:54.04]have fallen sharply relative to

[01:56.09]the prices of most other goods and services.

[01:58.21]As agricultural prices have fallen,

[02:01.50]many households have decreased

[02:03.77]their total expenses on food.

[02:05.31]Even though the quantity of a product purchased

[02:08.89]generally increases when its price falls,

[02:11.22]total expenses on it may decline.

[02:14.42]Now the passage will be read again.

[02:19.31]Many college students today own personal computers

[02:23.82]that cost anywhere from ¡ç1 000 to perhaps ¡ç5 000 or more.

[03:00.16]This is the main reason why computers cost
