Let children learn to judge their own work. A child learning 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 difference between the languages he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people. In the same way, when children learn to do all the other things they learn to do without being taught-to walk, run, climb, whistle, ride a bicycle-compare those 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 own mistakes for himself,
let alone correct them. We do it all for him. We 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. Soon he becomes dependent on the teacher. Let him do it himself. Let him work out, with the help of other children if he wants it, what this word says, what 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 work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let’s end this nonsense of grades, exams, marks, Let us throw them all out, and let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know.
Let them get on with this job in the way that seems sensible to them. With our help as school teachers if they ask for it. The idea that there is a body of knowledge to be learnt at school and used for the rest of one’s life is nonsense in a world as complicated and rapidly changing as ours. Anxious parents and teachers say, “But suppose they fail to learn something essential they will need to get in the world?” Don’t worry! If it is essential, they will go out into the world and learn it.

某工程为 10 层钢筋混凝土框架结构。某施工企业现场项目部在自购钢筋进场之前,按要求向监理工程师提供了合格证,并经过见证取样复验合格。监理工程师同意该批钢筋进场使用。钢筋接头采用绑扎、电渣压力焊两种,在隐蔽工程验收检验钢筋焊接质量时,怀疑钢筋母材不合格。经过对该批钢筋重新检验,最终确认该批钢筋不合格。监理工程师随即发出不合格项目通知,要求施工单位拆除重做,同时报告业主。承包商认为本批钢筋使用前已经过监理工程师见证取样,复检合格 ,且同意使用。
问题：
1、为确保工程质量 ,在进行该项目质量控制过程中,该施工企业应采取哪些主要对策。
2、该钢筋工程质量验收内容有哪些?如何组织验收 ?
3、现场质量检查有哪些方法?

The food we eat seems to have profound effects on our health. Although
science has made enormous steps in making food more fit to eat, it has , atthe
same time, made many foods unfit to eat. Some research has shown that perhaps
eighty percent of cancer is related to the diet as well, especially cancer the
colon . Different cultures are more prone to contract certain illnesses because
of the food that is characteristic in these cultures. That food related to
llness is not a new discovery. In 1945 , government researchers realized that
itrates and nitrites, commonly used to preserve color in meats, and other food
dditives, caused cancer. Yet, these carcinogenic additives remain in our food,
nd it becomes more difficult all the time to know which things on the pack ging
labels of processed food are helpful or harmful.The additives which we eat are
not all so direct. Farmers often give penicillin to beef and poultry, and
because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are administered to animals not for medicinal purposes,
but for financial reasons. The farmers are simply trying to fatten the animals
in order to obtain a higher price on the market. Although the Food and Drug
Administration (FDA) has tried repeatedly to controlthese procedures, the
practices continue.
