雅思考試包括口語、聽力、閱讀、寫作四個部分，相對於託福或國內其它的英語考試，更能夠全面鍛鍊學習者的英語聽說讀寫能力。以下是yjbys網小編整理的關於雅思寫作數字變化表達方式，供大家備考。
12個單詞
趨勢 描述單詞 注意事項
上升 grow, climb, soar 1.其中“soar”和“sink”為極限詞彙，不能新增任何修飾;
2.在句子和文章中，事實上很少用到上述動詞的原型，相反使用最多的是它們的“過去式”，以及對應的名詞;
3.上升和下降需要和數字建立連線，可供選擇的'介詞to, by, of
To 配合動詞和名詞，表示“達到”
By/of 表示“變化了”;by跟在動詞後面，而of跟在名詞後面
下降 drop, fall, sink
平穩 stay unchanged at+不變的值
波動 vary between…and…(兩個極值; 名詞 fluctuation between…and…
程度 dramatically (significantly)劇烈的;progressively (gradually)逐漸的;slightly (slowly)緩慢的 表中所提供的單詞均為“副詞”，需搭配動詞使用;如果需要搭配、修飾“名詞”，則上述的詞彙應變為“形容詞”，即：dramatic, progressive, slight
3個重要的句式：
例句：在2005年到2006年間，當澳洲當地的水費usage charge增加了每千升per kiloliter 0.25元。(看看下面的三種不同表達形式)
(1) 主謂句(強調量詞的變化)
The usage charge in Australia grew by $0.25 per kiloliter during 2005-2006.
(2) 主謂賓句(強調量詞的變化，詞性變化)
The usage charge in Australia had a growth of $0.25 per kiloliter between 2005 and 2006.
(3) 被動句(強調變化本身)
A growth of $0.25 per kiloliter was found in the usage charge in Australia over 1 year to Year 2006.
NB: 表示時間的變化，常用的手法
From…to…; between…and…; during…-…; for/over時間差to終止時間
4個連線詞
第一種：一個物件在不同時期的變化(時間變化)，before /, after which
第二種：不同物件的比較 similarly (= The similar pattern is found in…) / however (In contrast,)
例題：
在過去的2年中，中國的GDP(Gross Domestic Production)增長了10%，預計在明年GDP仍可能增長8%左右。但是，日本的GDP在過去的2年中，基本呈現下降趨勢，而且預計明年下降得更猛烈。
In the recent 2 years, GDP of China has grown by 10%， after which it is estimated to climb by 8% next year. In contrast, a dropping trend, in the last 2 years, has been found in that of Japan, before it is predicted to be more dramatic。
當不是特別能夠確定圖表的具體數值時，我們可以在數字前加上about, around, nearly, approximately, or so等一些比較模糊的副詞修飾。
看一道例題：
During 1979- 1999, visits overseas by UK residents, about 12 million in 1979, had a growth to nearly 52 million. The similar pattern was found in visits to the UK by international residents from around 10 million to 30 million. 6.5分
UK residents, about 12 million in 1979, had a growth to nearly 52 million. The similar pattern was found in visits to the UK by international residents from around 10 million to 30 million, but climbing slower than the former. 7分
In 1979, visits abroad by UK residents, 2 million more than those to the UK by overseas residents, was 12 million, after which a dramatic rise to nearly 52 million was found in 1999, when the similar pattern was seen in the visits to the UK by international residents to nearly 30 million. 8分
NB：高分的內容應該是資訊量較大的，而且處處充斥著比較和對比的感覺。在一個句子中，充分利用“插入語-解釋和補充”，以及非限制性定語從句來補充其他的內容，最後利用similarly或however進行比較。
