     We can achieve knowledge either actively or passively. We achieve it actively by direct experience,

by testing and proving an idea, or by reasoning.

     We achieve knowledge passively by being told by someone else. Most of the learning that takes place

in the classroom and the kind that happens when we watch TV or read newspapers or magazines is

passive. Conditioned as we are to passive learning, it's not surprising that we depend on it in our

everyday communication with friends and co-workers.

     Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told

even when it is little more than hearsay and rumor(谣言).

     Did you ever play the game Rumor? It begins when one person writes down a message but doesn't

show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn,

whispers it to still another, and so on, through all the people playing the game. The last person writes

down the message word for word as he or she hears it. Then the two written statements are compared.

Typically, the original message has changed.

     That's what happens in daily life. The simple fact that people repeat a story in their own words

changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative

touch to a story, trying to improve on it, stamping(打上标记)it with their own personal style. Yet those

who hear it think they know.

This process is also found among scholars and authors: A statement of opinion by one writer may be

restated as a fact by another, who may in turn be quoted by yet another; and this process may continue,

unless it occurs to someone to question the facts on which the original writer based his opinion or to

challenge the interpretation he placed upon those facts.

1. According to the passage, passive learning may occur in _______.

A. doing a medical experiment    

B. solving a math problem

C. visiting an exhibition    

D. doing scientific reasoning

2. The underlined word "it" in Paragraph 2 refers to _____.

A. active learning

B. knowledge

C. communication    

D. passive learning

3. The author mentions the game Rumor to show that _____.

A. a message may be changed when being passed on 

B. a message should be delivered in different ways

C. people may have problems with their sense of hearing

D. people tend not to believe in what they know as rumor

4. What can we infer from the passage?

A. Active learning is less important.

B. Passive learning may not be reliable.

C. Active learning occurs more frequently.

D. Passive learning is not found among scholars. 

问答题 案例分析题

背景

某幕墙公司通过招投标从总承包单位承包了某机关办公大楼幕墙工程的施工任务。承包合同约定,本工程实行包工包料承包,合同工期180个日历天。在合同履行过程中发生了以下事件:

事件一:按照合同约定,总承包单位应在8月1日交出施工场地,但由于总承包单位负责施工的主体结构没有如期完成,使幕墙开工时间延误了10d。

事件二:幕墙公司向某铝塑复合板生产厂订购铝塑复合板,考虑该生产厂具有与本工

程规模相符的幕墙安装资质,幕墙公司遂与该厂签订了铝塑复合板幕墙供料和安装的合同。总承包单位提出异议,要求幕墙公司解除铝塑复合板安装合同。

事件三:对办好隐蔽工程验收的部位,幕墙公司已进行封闭,但总承包单位和监理单位对个别施工部位的质量还有疑虑,要求重新检验。

事件四:工程竣工验收前,幕墙公司与发包人签订了《房屋建筑工程质量保修书》,保修期限为一年。

问题

(1)事件一中,幕墙公司可否要求总包单位给予工期补偿和赔偿停工损失?为什么?

(2)事件二中,总承包单位要求幕墙公司解除铝塑复合板安装合同是否合理?为什么?

(3)事件三中,幕墙公司是否可以因这些部位已经进行过隐蔽工程验收而拒绝重新检验?重新检验的费用应由谁负责?

(4)指出事件四中《房屋建筑工程质量保修书》中的保修期限的错误,说明理由并修正保修期限。
