The fast speed of modern society require us to finish our job with both efficency and accuracy. What is a debate is that whether we should work quickly and risk making mistakes or should work slowly and make sure that everything is correct. From my point of view, I prefer the latter one for the following reasons.It is well saying that slow carving perfect a sclupture. If we persue the velosity overuan, sometimes it may cause the problem which is relaled to human 's safety and lives. One of the best examples is the building construction,  which need a few years to finish, Since the main function of a building is to provide a place to people's living, working ans study, it should have a considerably high quality. As we all know that, some house builders construct a department in a remarkably short time in oder to make profit. As a result, the security of a building cannot be guarteened. Once in the Wenchuan earthquake, some buildings did not have a strong structure due to rapid work, which did harm to many peoples in the buildings who may can be a survival.Moreiver, Some kinds of of job do need correction than efficency.  As we all can see, it will need a extraordinaty long time to make up a satelte or a rocket. Most of the governments in the world invest much mony and time on this perspect. When the engineers devoting themselves in making the rockets and space suits, they will cacluate the math and phycial formulas about gravity, measure the distane between the earth and other plantes and so on. All of these need to make sure every step is correct and withour any mistaken. The scientists cannot afford to make a mistake if the rockets sent in fail. In that case, carrection is the most central cocerning without any doubt. Like the rocket named Chang e which was prduced in China, spend nearly 10 ten years to finish,. One of its succes sending is the high concentration of every parts.However, we cannot deny that the advantages of working quickly though we have to risk making mistakens.
