雅思考試Task1寫作常識：data的具體表達(dá)法
data在某一個(gè)時(shí)間段固定不變：fixed in time
在一系列的時(shí)間段中轉(zhuǎn)變：changes over time
持續(xù)變化的data在不同情況下:
增加：increase / raise / rise / go up ...
減少：decrease / grow down / drop / fall ...
波動(dòng)：fluctuate / rebound / undulate / wave ...
穩(wěn)定：remain stable / stabilize / level off ...
最常用的兩種表達(dá)法：
動(dòng)詞 + 副詞形式(Verb+Adverb form)
形容詞 + 名詞形式(Adjective+Noun form)

+in the number of XXX from (第一時(shí)間) to (第二時(shí)間) / between (第一時(shí)間) and (第二時(shí)間)
描述穩(wěn)定的data：
The number of XXX remained steady/stable from (第一時(shí)間) to (第二時(shí)間) / between (第一時(shí)間) and (第二時(shí)間)
The number of XXX stayed the same from (第一時(shí)間) to (第二時(shí)間) / between (第一時(shí)間) and (第二時(shí)間)
There was little change / hardly any change / no change in the number of XXX from from (第一時(shí)間) to (第二時(shí)間) / between (第一時(shí)間) and (第二時(shí)間)
描述不同狀態(tài)的data
Noun form:
steady drop / sharp rise peak / dramatic fall / sharp drop
Verbal form:
(to) bottom out / (to) reach the bottom / (to) increase gradually / (to) reach a plateau / (to) remain steady

低點(diǎn)極值：
