Faces, like fingerprints, are unique. Did you ever wonder how it is possible for us to recognize people? Even a skilled writer probably could not describe all the features that make one face different from another. Yet a very young child --- or even an animal, such as a pigeon --- can learn to recognize faces. We all take this ability for granted. We also tell people apart by how they behave. When we talk about someone’s personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others.

Like the human face, human personality is very complex. But describing someone’s personality in words is somewhat easier than describing his face. If you were asked to describe what a nice face looked like, you probably would have a difficult time doing so. But if you were asked to describe a nice person, you might begin to think about someone who was kind, considerate, friendly, warm, and so forth.

There are many words to describe how a person thinks, feels and acts. Gordon, an American psychologist, found nearly 18,000 English words characterizing differences in people’s behavior. And many of us use this information as a basis for describing, or typing his personality.

Bookworms, conservatives（保守派）, military（军人或军事的）types --- people are described with such terms. People have always tried to type each other. Actors in early Greek drama wore masks to show the audience whether they played the villain’s or the hero’s role. In fact, the words “person” and “personality” come from the Latin persona, meaning mask. Today, most television and movie actors do not wear masks. But we can easily tell the good guys from the bad guys because the two types differ in appearance as well as in actions.

某工程，施工合同中约定，工期19周，钢筋混凝土基础工程量增加超出15%时，结算时对超出部分按原价的90%调整单价。经总监理工程师批准的施工总进度计划如图2—1所示，其中A、C工作为钢筋混凝土基础工程，B、G工作为片石混凝土基础工程，D、E、F、H、I工作为设备安装工程，K、L、J、N工作为设备调试工作。

施工过程中，发生如下事件。

事件1：合同约定A、C工作的综合单价为700元/m³。在A、C工作开始前，设计单位修改了设备基础尺寸，A工作的工程量由原来的4200m³增加到7000m³，C工作工程量由原来的3600m³减到2400m³。

事件2：A、D工作完成后，建设单位拟将后续工程的总工期缩短2周，要求项目监理机构帮助拟定一个合理的赶工方案，以便与施工单位洽商，项目监理机构提出的后续工作可以缩短的时间及其赶工费率见表2-1。

问题

事件1中，设计修改后，在单位时间完成工程量不变的前提下，A、C工作的持续时间分别为多少周对合同总工期是否有影响为什么A、C工作的费用共增加了多少
