雅思考试，下面我们要讨论用不同方法描述变化趋势，这样能避免词汇的单一性，因为有一项评分标准叫做LexicalResourceandGrammaticalRangeandAccuracy也就是选词和语法是否准确恰当。

首先考考自己能想到多少表示以下意思的同义词，

如果每一项能写出3-4个表明你已经非常不错了，比如rise,climb,rocket,soar,但是这四个动词还是有增加程度上的区别，仔细区分一下。

Verbstodescribeageneralincrease

Goup

Rise

Increase

Climb

Verbstodescribeasudden,largeincrease

Jump

Shootup

Rocket

Verbstodescribeageneraldecrease

Godown

Fall

Decrease

Drop

Verbstodescribeadecrease

Plunge

Plummet

为了更加丰富你的表达方法，如果你还记得我们第三篇介绍的一些副词，例如slightly,roughly,approximately等等，你可以在用来描述generalincrease/decrease的动词前搭配使用，如slightlyincreaseby20%,dropapproximatelyby10%等等。

然后我们看副词的不同表达方式：

Speed

Todescribeachangethathappensquickly,youcanalsouserapidlyorsharply.

Todescribeachangethathappensslowly,youcanalsousegradually.

Todescribeachangethathappensbyapproximatelythesameamounteachmonth/yearetc.youcanusesteadily.

Amount

Todescribealargeincreaseordecrease,youcanuseconsiderably,significantlyorsubstantially.

Todescribeasmallerincreaseordecrease,youcanuseslightlyormoderately.

别忘了，不仅可以用动词副词"的表达方式，还可以用形容词名词"以及see/witness"的方法表示，例如

Youcanusetheverbadverbformsabove-‘salesincreasedsubstantiallyin2016.’

Youcanalsousetheadjectivenounformtogetherwiththereis/was.Forexample,‘therewasasubstantialincreaseinsalesin2016,followedbyaslightdropin2017.’Becarefultousethecorrectprepositions!

Anotherpossibilityistousetheverbseeorwitness-‘2016sawasubstantialincreaseinsales.’

实际变化情况远比上述内容多得多，我们直观地来感受一下：

接下来我们进行实操：

Hoteloccupancyincreased__________betweenJanuaryandApril.Thenumberofguestsincreased_____________inMay.Therewasasteep___________inthenumberofguestsbetweenMayandJune.July_________amassive___________inthenumberofguests.Guestnumbersrose________inAugustbeforedroppingback______overthenextthreemonthsto40%.

Answer:

steadily

sharply

drop

saw

increase

slightly

significantly
