arise.Such warnings must be displayed prominently. Background information may be necessary in certain situations.Relevant background information helps justify the steps to be taken,especially in the case where your steps differ from previous practice.Experts may want to know why they should do what you are telling them to do. Sequenced instructions makes the central component of instructions.It is the sequence of steps the reader will need to follow.Some products need fewer steps while others require many more.Some instructions may need to be illustrated with drawings or diagrams,especially where operations are very complex or abstract. Illustrations make the steps easier and more vivid than mere words. Trouble-shooting guide informs the reader of problems that may arise and the proper way of handling them.Usually,some problematic situations are listed along with ways to address them.This makes it possible for the reader to put the situation right by himself or to seek external help. 2.组织结构 One good way to make operating instructions easy to follow is to divide them into short,simple steps.These steps should be given following a proper sequence and they should not contain gaps or loops.Where there is a large number of steps,they are divided into sections with a subheading for each.Continuous Arabic numbers are used throughout to indicate the continuity of the steps. Prose or list?The steps can be presented in continuous prose or a list.Compared with prose,a list can save the reader time by allowing them to see at a glance specific items, questions,or directions.An additional advantage is that the nearly uniform pattern may make the instructions easier to absorb.The list also helps the reader by breaking up complex statements into manageable chunks of information.For example,each instruction on the list represents one small step of action,and leads logically from the first step to the last of the operation. This does not mean that a list is always more effective than prose.Take a look at this example: Step 1 Hold the CONTROLkey down. Step 2 Press the BELLkey before releasing the CONTROLkey. The two actions are performed simultaneously.In this case,it is much clearer to combine the two actions in one sentence:arise. Such warnings must be displayed prominently.
