導(dǎo)讀：對(duì)于雅思寫作，國(guó)內(nèi)很多學(xué)生強(qiáng)調(diào)模板運(yùn)用的重要性以及高效率，就這一點(diǎn)，強(qiáng)調(diào)寫作思路的訓(xùn)練，而雅思寫作模板更多的實(shí)在臨考前作為錦上添花的作用，雅思寫作模板可能有千百種的寫作手法和句型，但究其更本質(zhì)的內(nèi)在，他們的“骨架”寫作思路往往都是相似的。

　　根據(jù)分析，雅思寫作大作文出題都是比較典型的議論文類型，因此如何論證觀點(diǎn)就是雅思寫作能否獲得高分的關(guān)鍵，這個(gè)邏輯推理的過程必須嚴(yán)密。

　　1、對(duì)比論證

　　對(duì)于是否應(yīng)該做某事這樣結(jié)構(gòu)的雅思寫作題目，天道培訓(xùn)老師推薦的是通過對(duì)比的方式來(lái)引導(dǎo)整個(gè)論證過程，兩種截然相反或者不同的事物對(duì)于，其結(jié)果的利弊也就會(huì)更為凸顯。

　　下面這段就是節(jié)選自一篇關(guān)于大學(xué)前是否應(yīng)該用一年時(shí)間旅游或者工作的雅思寫作范文，之所以能成為范文，很大程度上都得益于對(duì)比關(guān)系貫穿了整個(gè)論證過程，這篇文章看起來(lái)緊湊而嚴(yán)謹(jǐn)。

　　“Those who believe in the measure say that students benefit a lot from traveling or working for a year before their formal university education. First, they can more broadly acquainted themselves with the society, deepen their understanding of the outside world, and thus better coordinate their objectives of learning with the needs of the society. In contrast, by immediate entrance to university they can not steer the direction of their study well and may display a poor combination of the theory with practice. Second, study at high school is really exhausting, especially when to win college admission. So it is necessary to grant these children a relatively long period of relaxation or buffer, say, traveling or working for a year, to loosen the chords of their brain, so that when they go back to school later again, they can become completely refreshed and rejuvenated.”

　　可以看到這是這一段就是論證的過程，而In contrast作為明顯的轉(zhuǎn)折信號(hào)詞，在此之前，先從正面闡述了如果能在上大學(xué)前去旅行或者工作一年，那么學(xué)生就能融入社會(huì)，再進(jìn)入大學(xué)就能更好地把理論和實(shí)際結(jié)合起來(lái)。In contrast之后則更詳細(xì)的從反面闡述了直接進(jìn)入大學(xué)的壞處，這樣正反結(jié)合的對(duì)比論證寫作思路，很大的一個(gè)優(yōu)勢(shì)就是，正面很突出，反面也很明顯，有足夠的說服力。

　　相比之下，如果同學(xué)們一直采用正面的論證，以大學(xué)前去旅游或者工作的優(yōu)勢(shì)貫穿整篇文章的話，或許你也可以有充足的論據(jù)，很好的論證，但是總會(huì)顯得比正反論證“無(wú)力”許多，要記住，正和反是個(gè)很好的搭檔，一個(gè)簡(jiǎn)單的比喻，如果是你用黑色的背景，再用黑色的字，那么不管字多大都不會(huì)有人能看出它來(lái)。黑和白在設(shè)計(jì)的色彩搭配中為什么是經(jīng)典?就得益于兩者通過對(duì)面后能加強(qiáng)效果。

　　　2、假設(shè)論證

　　提出假設(shè)——推出假設(shè)的后果——最后再提出結(jié)論，這在很多雅思寫作話題中也是經(jīng)常被運(yùn)用到的寫作思路和論證方法，它的優(yōu)勢(shì)在于假設(shè)能夠?qū)?ldquo;很虛”“很空”的話題一下子具體到具體的事物上，這樣再論證結(jié)果的話就不會(huì)顯得“空泛”。

　　下面就是一篇論證石油是經(jīng)濟(jì)和政府命脈的雅思寫作話題，而石油本身來(lái)說，其實(shí)離每一個(gè)考生個(gè)人的生活還是比較遙遠(yuǎn)的，因此在假設(shè)石油匱乏的前提下，同學(xué)們就可以將石油帶來(lái)的影響波及到農(nóng)業(yè)、工業(yè)等等一連串與我們生活息息相關(guān)的東西上，這樣“石油是經(jīng)濟(jì)和政府命脈”這樣一個(gè)虛、泛的話題就具體化了。

　　Then, since the transportation system is the lifeline of a country’s economic activities, its paralysis would lead to the disintegration of the economy, either industry of farming or daylife. Suppose all the means of transportation were halted for lack of oil, factories with insufficient raw materials would have to close, workers would be out of work, and ripe farm crops would have to stay in the fields at the mercy of rain and storms. People would try to store food and the price of all commodities would go up. If we take those power stations run by oil into account, situations would become even worse. In this sense, oil decides the fate of the whole economy and that of the government.

上面這一段范文節(jié)選，假設(shè)了如果沒有石油供應(yīng)下對(duì)農(nóng)業(yè)、工業(yè)將產(chǎn)生的一系列的惡性影響，而我們目前的生活，石油還是比較有供應(yīng)的，因此考生不用提出石油富足的假設(shè)，其實(shí)在大家的眼中，已經(jīng)形成了一種無(wú)形的對(duì)比——“石油匱乏的生活”和“石油還足夠供應(yīng)”的對(duì)比。某種程度上，上面這一段的論證其實(shí)就是結(jié)合了假設(shè)論證和對(duì)比論證兩種方法的。
