40、onship.Linear orderEach sentence builds on the preceding one and looks ahead to the following sentence.WaysThe coherence between sentences can be achieved by the linear order.ContructionThe typical construction of the linear order is“Given+New”.(1)given A to new BA refrigerator A is mainly composed
41、of a compressor,a condenser and an evaporator,which are connected one another by tubes B.(2)given B to new CThe compressor B compresses the low-pressure gas from the evaporator and changes it into hot-high-pressure gas C.(3)given C to new DThis resultant hot-high-pressure gas C enters the condenser,
42、where heat is transferred into the air by radiation and the gas condenses to become cold high-pressure liquid D.(4)given D to new EThis liquid D passes through the evaporator,where the pressure on the liquid is reduced E.(5)given E to new FThe liquid with reduced pressure E turns into gas by absorbi

44、h.deductiveIf the material is highly technical and difficult,it is better to place it at the beginning.3.Using Helpful TransitionsPurpose:They lead readers from one point to the next so that the readers can easily understand the entire document.Definition:Transitional words,or Logical connectors,are
45、 words indicating relations between ideas,such as moreover,however,finally,etc.Chinese achieves coherence mainly by meaning through context.1也有一些恒星非常小，有的比地球还小。2可是可是这种恒星的物质，密度特别大。3火柴头那么大的一点点就抵得上十多个成年人的重量。4用白金造成同样大的一个球，重量才抵得上它的二千分之一。5人到了这种星星上休想站得起来 English achieves coherence mainly by form through tra
