charts are organised in different ways and so you need to decide on the organisation of each one.Concluding sentencesYour report may end with one or two sentences which summarise your report to draw a relevant conclusion.Grammar and vocabularyAvoiding repetitionYou will receive a higher mark if your writing uses a range of structures and vocabulary correctly rather than a limited number. For example, the candidate who writes:The number of cases of X disease started at 50 in 1965 and then went up to 200 in 1970 and then went up to 500 in 1980 and then went down to zero in 1990.will lose marks for being repetitive. You should therefore practise writing reports using a wide variety of terms to describe the different movements in the graphs and different structures to vary your writing.Describing trendsTrends are changes or movements. These changes are normally expressed in numeric items, for example, population, production volumes or unemployment. There are three basic trends:Expressing movement: nouns and verbsFor each trend there are a number of verbs and nouns to express the movement. We can use a verb of change, for example:Unemployment levels fellOr we can use a related noun, for example:There was a fall in unemployment levelsDirectionVerbsNounsRose (to)Increased (to)Went up (to)Climbed (to)BoomedA riseAn increaseGrowthAn upward trendA boom (a dramatic rise)Fell (to)Declined (to)Decreased (to)Dipped (to)Dropped (to)Went down (to)Slumped (to)Reduced (to)A decreaseA declineA fallA dropA slump (a dramatic fall)A reductionLevelled out (at)Did not changeRemained stable (at)Remained steady (at)Stayed constant (at)Maintained the same levelA levelling outNo changeenormousenormouslysteepsteeplysubstantialsubstantiallyconsiderableconsiderablysignificantsignificantlymarkedmarkedlymoderatemoderatelyslightslightlysmall the difference between two levelsbyofbyoftotoby,and16
