Fill in the blanks with the suitable words or phrases given below.(3×62)is parallel to auxiliary drafted internal configuration extremely sufficient When a symmetrical object is 1 , two views are 2 to represent it（typically, one view is omitted）. A partial view can be used to substitute one of the two views. Sectional and 3 views are also commonly used to present part detail. Sectional views are 4 useful in displaying the detailed design of a complicated 5 . If the section is symmetrical around a centerline, only the upper half needs to be shown. The lower half is typically shown only in outline. Casting designers often employ sectional views to explode detail. When a major surface is inclined to three projection planes, only a distorted picture can be seen. An auxiliary plane that 6 the major surface can be used to display an undistorted view.III.

Translate the following paragraphs. (20)Because of the highly competitive nature of most manufacturing businesses, the question of finding ways to reduce cost is ever present. A good starting point for cost reduction is in the design of product. The design engineer should always keep in mind the possible alternatives available to him in making his design. It is often impossible to determine the best alternatives without a careful analysis of the probable production cost. Designing for function, interchangeability, quality, and economy requires a careful study of tolerances, surface finishes, processes, materials, and equipments.线第1页，共1页
