A公司承接了一项1000m3的球罐组装焊接工程。球罐的质量要求很高,各项要求都严格,焊接前为减少焊接应力要求采取预热措施并提出了预热方法,焊接后采用自动控温的火焰加热装置进行整体热处理。施工要求除部分焊接采用手工外,其余均采用自动焊接。施工完毕后进行检验,主要是对焊接试板的检验,球罐强度和严密性试验以及几何尺寸的检验。检验结果发现焊接试板的冲击试验结果不符合要求,通过对球罐的充水试验,发现其壁底不够严密。于是要求复验,并进行返修,再经检验,工程设备完全符合要求,并无质量问题后交付使用。

Every artist knows in his heart that he is saying something to the public. Not only does he want to say it well, but he wants it to be something which has not been said before. He hopes the public will listen and understand—he wants to teach them, and he wants them to learn from him.
What visual artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experiences into shapes and colors, not words. They seem to feel that a certain selection of shapes and colors, out of the countless billions possible, is exceptionally interesting for them and worth showing to us. Without their work we should never have noticed these particular shapes and colors, or have felt the delight which they brought to the artist.
Most artists take their shapes and colors from the world of nature and from human bodies in motion and repose; their choices indicate that these aspects of the world are worth looking at, that they contain beautiful sights. Contemporary artists might say that they merely choose subjects that provide an interesting pattern, that there is nothing more in it. Yet even they do not choose entirely without reference to the character of their subjects.
If one painter chooses to paint a gangrenous leg and another a lake in moonlight, each of them is directing our attention to a certain aspect of the world. Each painter is telling us something, showing us something, emphasizing something m all of which means that, consciously or unconsciously, he is trying to teach us.

It is hard to explain what a painter is saying, because ______ .

A.most painters do not express themselves well

B.a painter uses unusual words and phrases

C.a painter uses shapes and colors instead of words

D.many painters do not say anything
