某公路工程所需的主要建材有路基土方填料、砂石材料、水泥、沥青材料、沥青混合料和钢材等。所有材料均由项目部自己采购和组织运输。项目部材料采购部门拟按工程量清单→材料供应计划→材料用量计划→材料用款计划→材料采购计划的顺序进行材料计划管理,并对几种材料的主要工程指标及工程特性提出了如下要求(摘要):
(1)对于碎石提出了可松散性要求。
(2)为区分砂的粗细度,提出了砂的平均密度和湿度要求。
(3)对于水泥,提出了针入度的要求。
该项目在施工过程中,项目部有关部门通过资料分析,发现混凝土工程的实际成本比计划成本增加较多,主要原因是砂、碎石材料成本的增加。但有关资料表明,砂、碎石的购入原价与施工预算时的价格一致。
在工程施工中还发生了如下事件。
事件1:水泥混凝土结构局部出现了蜂窝、麻面,项目部认为并未影响结构,因此未做任何处理。
事件2:在满堂支架桥梁施工中,发生了支架垮塌,造成直接经济损失40万元。项目部在事后的第5天向上级公司进行了汇报。
事件3:在路基施工放样时,由于工期紧,项目部新购了一台全站仪后立即投入使用,并将一台超过规定周检确认时间间隔的仪器也投入使用,使路基工程按时完工。
[问题]

事件1中,项目部的做法是否正确如不正确,提出正确的处理办法。

答案

参考答案:事件1中,项目部的做法不正确。正确的处理办法:应采用整修的办法进行处理。

Let children learn to judge their own work. A child who learns to talk does not learn by being corrected all the time. If corrected too much., he will stop talking. He notices a thousand times a day the differences between the language he uses and the language those around him. Little by little, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught-to walk, run, climb, whistle, ride a bicycle-compare their performances with those of more skilled people, and slowly make the needed changes.

But in school we never give a child a chance to find out his mistakes and correct them himself. We do it all for his act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says , what the answer is to that problem, whether this is a good way of saying or doing this or not.

If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(daily) work? Our job should be to help the children when they tell us that they can’t find the way to get to measure their own understanding, how to know what they know or do not know.
