The new model is the highly interactive（互动的）learning model. We could also call it the conversational model, or the tutorial model. It is computer based, with the interaction between the student, or a small group of students, and learning programs are like the conversation between a student and a skilled tutor. Distance learning will be the main delivery method.

Student interaction with the learning material on the computer will use the student's natural language; it will seem like a conversation between a student and a human tutor. This is the key point of highly interactive, or conversational, learning units. Programs will ask questions in the student’s native language, and respond reasonably to free-form student input. Multiple choice and pointing will seldom be used; they often do not allow individualization (个体化) of education.

An important aspect of this model is that the computer will frequently store information about the student, about problems and about how far individual students have progressed. These records will be used often within the programs. Thus when a student returns to the learning activity, the computer knows about that student and knows where to begin the new part.

Global education is critical for the future, to get rid of poverty, corruption (腐败), violence and war, to solve major problems such as the lack of drinkable water, and to insure a happy life for all. Education should no longer be limited to the wealthy of the world, but should be available to everyone.

In the new distance learning environment learning can take place in markets, libraries, public buildings, learning centers, and the home. Gradually schools and universities will play a smaller role in learning, both because better learning can be delivered through such highly interactive material, and because such learning will be less costly for the individual student. Motivation (动机)is particularly important in a mastery-based distance learning, as the usual threats of traditional classrooms such as that of low grades are no longer possible.

Voice input will probably be the mode(模式) for this interaction. The new voice input systems from several companies are useful, cheap, and speaker independent in highly interactive learning. Keyboards may not be needed. Speech is a natural way for humans to communicate.

Students will work in small peer groups, about four. Other contacts with people, learning circles, will be possible, directly or electronically.

在某项工作的施工过程中，发生以下事件：

事件1：在对设备支架进行焊接过程中，每吨支架消耗人工10个工日，型钢1.08t，各种机械台班费400元，其他材料费320元。已知工程所在地的人工工日单价为28.5元，型钢的综合单价为每吨3 800元。

事件2：在施工过程中，由于勘察失误，业主决定改变某构件的位置，为此，承包商将原构件拆除，并重新安装，增加人工15个工日，机械台班0.5个台班。已知工程所在地人工工日单价为28.5元，该机械租赁费为700元/台班。

事件3：由于业主未能及时提供材料，导致承包商的人员窝工20个工日，该项工作的工期延长3天，并影响到总工期；某种机械设备窝工1个台班，该设备的窝工费为280元/台班。人员窝工费为23.5元/工日。

事件4：由于业主提供的动力故障，停工两天，但由于该项工作不在关键线路上，未影响总工期。人员窝工16个工日，人员窝工费为23．5元/工日。

事件5：为了确保工程质量，承包商经监理工程师批准采取了必要的技术措施，花费技术措施费2 000元。

事件6：在设备主体安装过程中，由于承包商提供的施工机械发生故障，造成人员窝工8个工日，设备主体安装过程延长2天。人员窝工费为23.5元/工日。针对上述四个事件，承包商向业主和监理工程师提出了费用索赔；同时针对事件1、2、4，提出了工期索赔。

根据事件1提供的信息，10t型钢支架的直接工程费为（）元。

A．41 040

B．44 240

C．47 090
