其次，如何展開一個(gè)觀點(diǎn)，關(guān)鍵在于是否能夠靈活運(yùn)用論證方式。常用的論證方式包括：解釋（explanation），延伸（extension），舉例（exemplification）和對比（contrast）等，如：
A lot of innovations are made with the aim of making money for a few. This is because it is the rich and powerful people in our society who are able to impose changes (such as in working conditions or property developments) that are in their own interests. （第二句為解釋論證）（《劍6》Test 4）
My view is that young people should be encouraged to broaden their horizons. That is the best way for them to get a clear perspective of what they are hoping to do with their lives and why. (第二句為延伸論證) （《劍5》Test 2）
To do this, we need to improve the choice of public transport services available to travelers. For example, if sufficient sky train and underground train systems were built and effectively maintained in our major cities, then traffic on the roads would be dramatically reduced.（第二句為舉例論證）（《劍8》Test 3）
The reasons for this trend may involve the recognition that a young adult who passes directly from school to university is rather restricted in terms of general knowledge and experience of the world. By contrast, those who have spent some time earning a living or traveling to other places, have a broader view of life and better personal resources to draw on. （第二句為對比論證）（《劍5》Test 2）
最后，提高寫作速度，其關(guān)鍵在于“固定”。要想在那么短的時(shí)間內(nèi)，在考場上高度緊張的狀態(tài)下寫出滿足字?jǐn)?shù)要求同時(shí)又非常優(yōu)秀的文章來，的確是非常困難的，但是雅思考官曾講過，考場上任何一篇優(yōu)秀文章中的每一個(gè)單詞都是經(jīng)過精心準(zhǔn)備的。因此，要想保證字?jǐn)?shù)同時(shí)又保證質(zhì)量，考前精心的準(zhǔn)備和設(shè)計(jì)是非常必要的。如：
固定開頭段
The late 20st century witnessed the every surging boom of advanced technology, which has brought attention to a heated debate concerning whether housework should be accomplished manually.
The late 20st century witnessed the ever surging boom of the world population, which has brought attention to a heated debate concerning whether people should be encouraged to move into skyscrapers.
固定常用句型
引導(dǎo)觀點(diǎn)或者解釋論證
It is a widely held perception that…
It is a commonly shared convention that…
舉例子
A great case in point is that…
延伸論證
So…that…
對比論證
主語+should/would/could/might + do +其他+ if +主語+did/be(were) +其他
連接兩個(gè)觀點(diǎn)
Not only…but also…
注意：文章中固定下來的內(nèi)容，尤其是開頭段、結(jié)尾段和文中的一些固定句型，最好不要摘自比較流行的輔導(dǎo)參考書，避免被考官認(rèn)為是抄襲或者模板。因此，考生需要自己總結(jié)或者在閱讀國外期刊雜志以及相關(guān)網(wǎng)站原版內(nèi)容的過程中不斷積累，同時(shí)還要保證固定內(nèi)容不能超出自身英語水平太高，否則，被考官認(rèn)定是語言記憶片段的可能性較大。把固定下來的內(nèi)容運(yùn)用熟練，就可以有效地提高寫作速度，從而滿足字?jǐn)?shù)要求。
