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“Lexical Resource and Grammatical Range and Accuracy“ 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。
Verbs to describe a general increase
Go up
Rise
Increase
Climb
Verbs to describe a sudden, large increase
Jump
Shoot up
Rocket
Verbs to describe a general decrease
Go down
Fall
Decrease
Drop
Verbs to describe a decrease
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general increase/decrease的动词前搭配使用，如 slightly increase by 20%, drop approximately by 10%等等。
然后我们看副词的不同表达方式：
Speed
To describe a change that happens quickly, you can also userapidlyorsharply.
To describe a change that happens slowly, you can also usegradually.
To describe a change that happens by approximately the same amount each month/year etc. you can usesteadily.
Amount
To describe a large increase or decrease, you can useconsiderably,significantlyorsubstantially.
To describe a smaller increase or decrease, you can useslightlyormoderately.
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
You can use theverb adverbforms above - ‘salesincreased substantiallyin 2016.’
You can also use theadjective nounform together withthere is/was. For example, ‘there was asubstantial increasein sales in 2016, followed by aslight dropin 2017.’ Be careful to use the correct prepositions!
Another possibility is to use the verbseeorwitness- ‘2016saw a substantial increase insales.’
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：

July_________a massive___________in the number of guests. Guest numbers rose ________in August before dropping back ______over the next three months to 40%.
