Text：The Price System

Everything has a price —each commodity and each service. The different kinds of human labor have prices, usually called “wages”. Everybody receives[1] money for what he sells and uses this money to buy what he wishes.

If more is wanted of any one commodity，say，shoes—a flood of new orders will be given for it. This will cause its price to rise[2]and more to be produced. Similarly, if more of a commodity such as tea becomes available than people want to buy at the last quoted market price, its price will be marked down by competition[3]. At the lower price people will drink more tea and producers will no longer produce quite so much. Thus, equilibrium of supply and demand will be restored. What is true of the markets for consumer goods is also true of markets for factors of production，such as labor and capital inputs[4]. If welders rather than glass blowers are needed，job opportunities will

be more favorable in the welding field[5]. The price of welders, their hourly wage, will tend to rise, while that of glass blowers will tend to fall[6]. Other things being equal, this will cause a shift into the desired occupation[7]. (204 words)

Notes:

[1]receive和accept的区别

receive用作动词，意为“接到”，指收到某物这一动作，本身有一定的被动性，不包含本身是否愿意接受的意思。例如：

他没在大学受过良好教育。

I received an invitation to the party yesterday, but I refused to accept it.

昨天我接到一份参加晚会的邀请，但我拒绝了接受。

accept也是作动词，意为“接受”，指经过考虑，由主观意志来决定接受，动作者本身是主动的。例如：He couldn't accept our suggestions but our gifts.

他们不能接受我们建议但接受了我们的礼品。

She was very glad to accept the invitation.

arise发生；起因（过去式arose，过去分词arisen）

Problems arose from the outset.

一开始就产生了很多问题。

Accidents always arise from the carelessness.

许多事故都源于粗心。

[3]Similarly, if more of a commodity such as tea becomes available than people want to buy at the last quoted

market price, its price will be marked down by competition.同样地，如果某种商品（例如茶）的供应量超过了人们以最近市场牌价购买的量，那么其价格将由于竞争而下降。

形容词available有以下含义：

1. 可用的，在手边的；可利用的

The swimming pool is available only in summer.

这个游泳池只在夏天开放。

2. 可得到的，可买到的

Is there water available around here?

附近弄得到水吗?

[5]If welders rather than glass blowers are needed，job opportunities will be more favorable in the welding

field.如果需要的是电焊工，而不是玻璃器皿吹制工，则电焊工种的就业机会就会更多。

1. rather tha n…而不是…

rather than 在句中起连接作用，连接两个平行结构，用以肯定前者，否定后者。它连接的平行结构可以是名词、代词、形容词、介词(短语)、动名词、分句、不定式、动词等。现分述如下：

(1) 连接两个名词或代词

He is an explorer rather than a sailor. 与其说他是一个海员，不如说他是一个探险者。

You rather than I are going to go camping. 是你而不是我要去野营。

注意：rather than 连接两个名词或代词作主语时，谓语动词应与rather than 前面的名词或代词在人称和数上保持一致。

(2) 连接两个形容词

The sweater she bought was beautiful rather than cheap. 与其说她买的这件羊毛衫便宜不如说它漂亮。

(3) 连接两个介词(短语)或动名词

We will have the meeting in the classroom rather than in the great hall. 我们是在教室里开会，不是在大厅里。

She enjoys singing rather than dancing. 她喜欢唱歌，而不喜欢跳舞。

(4) 连接两个分句

We should help him rather than he should help us. 是我们应该帮助他而不是他应该帮助我们。

(5) 连接两个不定式

I decided to write rather than (to) telephone. 我决定写信而不打电话。

注意：rather than 后接不定式时，不定式可以带to，也可以不带to, 如上句。但rather than位于句首时，则只能接不带to 的不定式。如：Rather than allow the vegetables to go bad, he sold them at half price. 他唯恐蔬菜烂掉，把它们以半价卖掉了。

(6) 连接两个动词

He ran rather than walked. 他是跑来的，而不是走来的。

2. favorable有利的，顺利的，良好的，赞同的

Most people were favorable to the idea.

大多数人赞成这个主意。

The conditions are favorable for opening a new business.

各种条件有利于开办新企业。

[6]The price of welders, their hourly wage, will tend to rise, while that of glass blowers will tend to fall.电焊

工的报酬，即每小时的工资就会趋于上升，而玻璃器皿吹制工的报酬，即每小时的工资就会趋于下降。

1. 句中的while用作等立连词，意思是“而”，“然而”，“则”，引导并列分句，表示两种不用情况或行为

作对比。例如：

Some men are rich, while others are poor.

有人富，有人穷。

We work for the people, while they work for the bosses.

我们为人民而工作，而他们为老板而工作。

The U.S.A. has immense mineral wealth, while Japan has comparatively little.

美国有丰富的矿藏，而日本的矿藏却较少。

He observed that feather fell to the ground slowly, while stones fell much faster.

他观察到羽毛落地很慢，而石头落地则快得多。

2. tend to趋于，倾向

Cheating in school tends to ebb and flow.

学校中的作弊现象也往往有涨有落。

Homes tend to use more electricity.

家庭用电有越来越多的趋势。

[7]Other things being equal, this will cause a shift into the desired occupation.如果别的条件都相等，这就会

导致人们向社会所需要的职业转移。

句中Other things being equal,是分词的独立结构，在句中用作条件状语。分词独立结构在句中作状语，其逻辑主语与主句的主语通常都是不同的，分词带有自已的逻辑主语。分词独立结构作原因、方式、条件、伴随、结果等状语。其表达形式为:名词 / 代词 + 分词。例如：

1) The meeting (being) over, we had an English Proficiency Test.

会议结束后，我们进行了英语水平测试。(时间状语)

2) There having been no rain, the plants withered.

因为一直没下雨，植物都枯萎了。(原因状语)

3) Weather permitting, we shall go hiking this weekend.

天气允许的话，这个周末我们徒步旅行去。(条件状语)

4) The naughty boy stood in the front of the snack bar, his face blushed.

那个淘气的小男孩站在小吃店前，脸涨得通红。(伴随状语)

5) All the money having been spent, we started looking for work.

钱全部花完之后，我们开始找工作。(原因状语)

6) He prayed silently, his eyes closed.

他闭着双眼, 默默祈祷。(伴随状语)

7) Class being over, the students went to the play-ground to watch the

ball game.

下课之后，学生们到操场去看球赛。(时间状语)

注：现在分词表示主动，逻辑主语发出、做出动作；过去分词表示被动，逻辑主语承受动作；分词的完成式表示的动作在谓语动词所表示的动作之前发生。

价格体系

每样东西都有其价格，无论是商品还是服务项目。人们的各种劳动也都有价格，通常称为“工资”。人人因出卖劳动力而获得货币，并用它购买自己所需的物品。

任何一种商品（例如鞋）的需求量增加了，大批新的定货单便会蜂涌而来。这就会造成该商品的价格上涨，产量增加。同样地，如果某种商品（例如茶）的供应量超过了人们以最近市场牌价购买的量，那么其价格将由于竞争而下降。人们将以低廉的价格喝到更多的茶，而茶农则不愿再生产那么多茶叶了。于是供与求就会重新恢复平衡。凡适用于消费品市场的原则，也同样适用于诸如劳动力、资本输入一类生产要素的市场。如果需要的是电焊工，而不是玻璃器皿吹制工，则电焊工种的就业机会就会更多，电焊工的报酬，即每小时的工资就会趋于上升，而玻璃器皿吹制工的报酬，即每小时的工资就会趋于下降。如果别的条件都相等，这就会导致人们向社会所需要的职业转移。

这些人们所从事的工作，被称之为经济活动。所有经济活动，共同构成了一个镇子，一座城市，一个国家乃至全世界的经济体系。这种经济体系，就是人们所做的和人们所需求的总和。他们从事的工作，或是提供他们所需要的物品，或是提供他们购买所需商品的金钱。
