作业题目及答案

作业题目及答案

第一章1.试述商品的两个因素、劳动二重性以及商品经济基本矛盾之间的关系。

要点:商品是用来交换的劳动产品,商品具有使用价值和价值两个因素。

使用价值是自然属性,价值是社会属性。

商品的使用价值和价值是对立统一的。

一方面商品必然既有使用价值又有价值,两者缺一不可,另一方面商品生产者的直接动机是实现价值,而使用价值只是价值的物质承担者,在交换中使用价值和价值必然分离。

生产商品的劳动具有二重性:劳动既是具体劳动,又是抽象劳动。

生产商品的具体劳动和抽象劳动是对立统一的,他们是同一劳动过程的两个方面,而不是两次劳动、两种劳动;对立性表现在具体劳动是实现抽象劳动的前提,在交换中卖者得到抽象劳动形成的价值,卖方得到各种具体劳动创造的使用价值,两者相分离。

正是由于生产商品的劳动具有二重性,所以商品才有二因素,具体劳动创造使用价值,抽象劳动形成价值。

商品经济是以商品交换为特征而进行生产的经济形式。

商品经济的基本矛盾是私人劳动和社会劳动之间的矛盾。

在以私有制为基础的商品生产中生产资料所有者自己决定生产的种类、数量等,直接表现在私人劳动,但是其具有社会劳动的性质。

私人劳动要被承认为社会劳动只有在流通过程中把产品当作商品来交换这种间接途径而实现。

解决私人劳动和社会劳动的矛盾的条件是商品交换,而交换则是依据具体劳动形成的不同使用价值为前提,将具体劳动转化为抽象劳动,从而表现出价值。

可见商品的二因素、劳动的二重性,都是缘于私人劳动和社会劳动的矛盾,都是生产商品的私人劳动具有间接的社会劳动的特性所决定的。

2.为什么说私人劳动和社会劳动的矛盾是简单商品经济的基本矛盾?要点:商品经济产生和存在的前提是社会分工和私有制。

在简单商品经济中,生产资料个人所有,每个生产资料的所有者自己决定生产什么,生产多少,生产直接表现为私人劳动;但是不同的商品生产者必须互通有无,把自己的产品和别人的交换,以满足自己的多样化需要,也就是说个人劳动是社会总劳动的一部分,具有社会劳动的性质。

它们之间的相互转化称为相变。

当水受热时,会从液态变为气态,这个过程称为蒸发;当水蒸气遇冷时,会从气态变为液态,这个过程称为凝结;当液态水受冷时,会从液态变为固态,这个过程称为凝固;当固态水受热时,会从固态变为液态,这个过程称为熔化。

2. 请描述一下植物的生长过程。

答案:植物的生长过程包括种子萌发、幼苗生长、成株生长和开花结果等阶段。

首先,种子在适宜的条件下吸收水分和养分,开始萌发,长出幼根和幼芽。

随着时间的推移,幼苗逐渐长大,形成茎、叶和根等器官。

成株期,植物继续生长,通过光合作用制造养分,同时进行呼吸作用和水分吸收。

Most months have a national holiday that has been arranged to becelebrated on a Monday. The holidays have all been decided to be celebrated on a Monday so that the workers may have 3-day weekends, that is, Saturday, Sunday and Monday in order to rest or travel or do things with their families. Major holidays in the United Statesinclude New Year’s Day, Christmas Day the day, when we remember the first settlers of the United States, called Thanksgiving Day. Inthese holidays most businesses close and the workers stay at home and celebrate with their families.Vacation can be from 2 weeks a year to 4 weeks a year. This usually depends on how long you’ve been working for a company, what type of position you have, whether you have a very high and important position and whether you can find someone to replace you. In this case, you might take a few days at a time rather than take one month all at once.
