2017雅思小作文表達(dá)變化的方法
導(dǎo)語(yǔ)：在雅思小作文寫(xiě)作的過(guò)程中準(zhǔn)確的表達(dá)變化是非常重要的一個(gè)項(xiàng)目，YJBYS小編建議大家在備考中可以組合一些簡(jiǎn)單句來(lái)進(jìn)行，這樣可以減輕備考的負(fù)擔(dān)，也可以在考試中有更好的發(fā)揮。那么我們可以應(yīng)用哪些簡(jiǎn)單句呢?
1.主+謂
此結(jié)構(gòu)是描寫(xiě)數(shù)據(jù)動(dòng)態(tài)變化的首選句型結(jié)構(gòu)，需注意的是主語(yǔ)必須是“數(shù)據(jù)”比如number, figure, percentage等，不能是其他名詞，而謂語(yǔ)動(dòng)詞也只能是不及物動(dòng)詞比如increase, drop等。下面我們來(lái)看幾個(gè)例子：
I.The number of visitors increased sharply between 1995 and 2005 inChina.
II.The percentage of people aged 15-46 dropped slightly by 10% during the 40 years.
III.The figure for college C rose gradually to 30,000 in2002.
IV.The number of aged people over 65 dropped slightly from 1960-1980.
V.The number of aged people over 65 fluctuated between 1 million and 1.2 million from 1940-1950.
2.主+謂+賓
此句型結(jié)構(gòu)的特點(diǎn)在于謂語(yǔ)動(dòng)詞必須是及物動(dòng)詞，比如witness, see等，賓語(yǔ)位置要用表示動(dòng)態(tài)變化的'名詞比如growth, reduction等，在主語(yǔ)位置上可以仍舊為數(shù)據(jù)，也可以是地點(diǎn)或者時(shí)間段。它對(duì)于用主謂結(jié)構(gòu)表達(dá)的句子可以作同義轉(zhuǎn)換，比如：
I.The number of visitors saw a sharp increase between 1995 and 2005 inChina.
II.China witnessed a sharp increase in the number of visitors between 1995 and 2005.
III.The years between 1995 and 2005 saw a sharp increase in the number of visitors in China.
3.there + be
此簡(jiǎn)單句型一般用于對(duì)于上述兩種動(dòng)態(tài)數(shù)據(jù)描寫(xiě)句型進(jìn)行同義轉(zhuǎn)換，be動(dòng)詞的時(shí)態(tài)一定要根據(jù)數(shù)據(jù)的時(shí)間來(lái)改變，否則很容易出錯(cuò)：
I.There was an increase in the visits from about 12 to 53 million from 1979 to 1999.
II.There was a sharp rise in the number of visitors between 1995 and 2005 inChina.
III.There was a slight decline in the number of aged people over 65 from 1960-1980.
IV.There was a fluctuation between 1 million and 1.2 million from 1940-1950.
