Then they put the knife down, transfer(转移) the fork to their right hand,and only then do they transport the food to their mouth . This is clearly funny, but it is considered good manners.Tables are generally laid with one knife and two forks. The outside fork is for the salad. There is no need for foreign visitors to eat the salad with only a fork, but if you do use your knife, remember to save it for the meat course. Even desserts(except ice cream) are eaten with a fork and the spoon by your dessert is meant to be for coffee ( but if you use it for your dessert no one will say anything).( )46.______ eat almost everything with a fork.A.People in the USAB.

A lot of people like to go by subway or by bus. The subway is the fastest way to get around in busy cities even during the rush hour .It is now becoming more and more popular. You don’t need to pay much money if you want to take a bus, but it i s much slower than the subway. To see a city closely by bike is a cheaper and better way. But the best and wisest way to get around in downtown areas is to go on foot.根据短文内容判断正误。

Working drawings are the complete set of standardized drawings specifying the manufacture and assembly of a product based on its design. The complexity of the design determines the number and types of drawings.Working drawings may be on more than one sheet and may contain written instructions called specifications. Working drawings are blueprints used for manufacturing products. Therefore, the set of drawings must:(a) completely describe the parts, both visually and dimensionally;(b)show the parts in assembly;(3)identify all the parts; and (4)specify standard parts. The graphics and text information must be sufficiently complete and accurate to manufacture and assemble the product without error.Generally, a complete set of Working drawings for an assembly includes: (1) Detail drawings of each nonstandard parts. (2) An assembly or subassembly drawing showing all the standard and nonstandard parts in a single drawing. (3) A bill of materials (BOM). (4) A title block. A detail drawing is a dimensioned, multiview drawing of a single pa rt, describing the part’s shape, size, material, and surface roughness, in sufficient detail for the part to be manufactured based on the drawing alone. Detail drawings are produced from design sketches or extracted from 3-D computer models. They adhere strictly to ANSI standards and the standard for the specific company, for dimensioning, assigning part numbers, notes, tolerances, etc. In an assembly, standard parts such as threaded fasteners and bearings are not drawn as details, but are shown in the班级： 姓名： 学号： --------------- ○ --------------------- ○ --------------------- ○ --------------------- ○ --------------------- ○ --------------------- ○ ---------------------assembly view. Standard parts are not drawn as details because they are normally purchased, not manufactured, for assembly. For large assemblies or assembled with large parts, details are drawn on multiple sheets, and a separate sheet is used for the assembly view. If the assembly is simple or the parts are small, detail drawings for each part of an assembly can be placed on a single sheet. Multiple details on a sheet are usually drawn at the same scale. If different scales are used, they are clearly marked under each detail. Also, when more than one detail is placed on a sheet, the spacing between details is carefully planned, including leaving sufficient room for dimensions and notes.1. Based on the message, which of the follow is wrong? A) standard p arts needn’t drawn as detailsB) for simple parts, sometimes needn’t to draw the detail working drawing C) for large assemblies details may drawn on multiple sheetsD) If different scales used in a single sheet, they should clearly marked under each detail 2. Working drawings for an assembly MAY NOT includes: ? A) BOM B) title blockC) An assembly or subassembly drawing D) Detail drawings of all parts. 3. For detail drawing, Which one of the following statement is not true? A) should not has different scalesB) Detail drawing can produced from design sketches or extracted from 3-D computer models. C) detail drawing is a dimensioned, multiview drawing of a single part D) should Adhere strictly to ANSI standards4. From the message we can infer ANSI is ? A) a set of law B) a set of notification C) an Organization D) IEEE government5. The topic of the message is ? A) How to design working drawings.B) working drawing’s character and the key influence of how to draw a working drawing C) In the design process, what should be considered?
