某建筑公司(乙方)于某年4月20日与某厂(甲方)签订了修建建筑面积为3000m2工业厂房(带地下室)的施工合同。乙方编制的施工方案和进度计划已获监理工程师批准。该工程的基坑开挖土方为4500m3,假设直接费单价为4.2元/m2,综合费率为直接费的20%。该基坑施工方案规定:土方工程采用租赁一台斗容量为1m3的反铲挖掘机施工(租赁费450元/台班)。甲、乙双方合同约定5月11日开工,5月20日完工。在实际施工中发生了如下几项事件:

(3) 5月19日接到监理工程师于5月20日复工令,同时提出基坑开挖深度加深2m的设计变更通知单,由此增加土方开挖量900m3
(4) 5月20日~5月22日,因下大雨迫使基坑开挖暂停,造成人员窝工10个工日;
(5) 5月23日用30个工日修复冲坏的永久道路,5月24日恢复挖掘工作,最终基坑于5月30日挖坑完毕。

Of all the areas of learning the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people.
"The burnt child fears the fire" is one instance; another is the rise of despots like Hitler. Both examples also point up the fact that attitudes stem from experience. In one case the experience was direct and impressive; in the other it was indirect and cumulative. The Nazis were indoctrinated largely by the speeches they heard and the books they read.
The classroom teacher in the elementary school is in a strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose word they respect.
Another reason it is true is that pupils often delve somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher’s method of handling such a unit would greatly affect his attitude toward Mexicans.
The media through which the teacher can develop wholesome attitudes are innumerable. Social studies (with special reference to races, creeds and nationalities), science matters of health and safety, the very atmosphere of the classroom... these are a few of the fertile fields for the inculcation of proper emotional reactions.
However, when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by cajoling or scolding them. She can achieve the proper effect by helping them obtain constructive experiences.
To illustrate, first grade pupils afraid of policemen will probably alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips.
Finally, a teacher must constantly evaluate her own attitudes, because her influence can be deleterious if she has personal prejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of all the facts.

The author implies that ______.

A.the teacher should guide all discussions by revealing her own attitude

B.in some aspects of social studies a greater variety of methods can be used in the upper grades than in the lower grades

C.people usually act on the basis of reasoning rather than emotion

D.children’s attitudes often come from those of other children
