從上述結(jié)構(gòu)我們看出作者的觀點(diǎn)是支持提供高科技媒體，但這個(gè)論證過程非常全面，它先在論證的第一段就退一步承認(rèn)其缺點(diǎn)，然后再就這一點(diǎn)進(jìn)行反駁，這個(gè)段落就是讓步段，參考之前提供句型，得出這一段：

Opponents of a high-tech library would argue that multimedia facilities are expensive. This may be true to some extent, because a DVD player is often more expensive than a bookshelf. However, with immense storage capacity, these new high-tech media can actually save the most valuable resource-space.

讓步段還可以運(yùn)用到討論類另一種結(jié)構(gòu)中，筆者謂之雙邊傾向論證。我們通過一個(gè)具體的實(shí)例來解釋這種論證結(jié)構(gòu)以及讓步在其中的用法。

There are social, medical and technical problems associated with the use of mobile phones. What forms do they take? Do you agree that the problems outweigh the benefits of mobile phones?

老師建議此題一定要認(rèn)真審題，因?yàn)檫@個(gè)問題模式對(duì)文章的結(jié)構(gòu)有著直接的影響。它有兩問，第一問要回答手機(jī)的三個(gè)方面的問題，第二問優(yōu)缺點(diǎn)討論，結(jié)合這兩問，得出文章結(jié)構(gòu)如下：

Introduction: State my opinion

The problems of mobile phones far exceed the merits.

Body: Ph 1 the benefits brought about by mobiles (Making concession)

Convenient, functional

Ph 2 the social, medial and technical problems of mobile phones

Conclusion: Restate my opinion

Although mobile phones have some benefits, the negative influences should not be overlooked.

看完結(jié)構(gòu)，不難理解雙邊傾向的結(jié)構(gòu)即兩個(gè)方面優(yōu)點(diǎn)和缺點(diǎn)都提及，作者的觀點(diǎn)是傾向其中一方的，那么不同意的那一方的論證段就可以理解為讓步段。結(jié)合句式，我們可以寫一下讓步段的topic sentence:

It is undeniable that mobile phones have facilitated our lives in many different ways.

接著可以列舉手機(jī)使用的幾個(gè)具體的優(yōu)點(diǎn)。這種讓步和單邊論證讓步的區(qū)別是它可以不用直接在這個(gè)段落后面反駁。

III? 結(jié)語

讓步段在論證過程中有著相當(dāng)廣泛的實(shí)戰(zhàn)意義，它可以幫助考生擴(kuò)展文章的字?jǐn)?shù)，達(dá)到要求，此外，它還能使得論證過程更加全面。老師推薦學(xué)生準(zhǔn)確使用此種論證方法，希望對(duì)寫作取得高分有切實(shí)的幫助。
