Paragraph 2

First, the lecturer states that removing dead trees is not good for the health of a forest because it deprives it of nutrients necessary for future tree growth, which dead trees release into the soil as they decompose. In contrast, the reading passage states that removing old trees provides more space in which new generations of fresh trees can grow uninhibited by deadfall.
　　此段功能：
　　以 L 的觀點(diǎn)為主，L 說(shuō)移除死樹(shù)對(duì)森林是無(wú)益的因?yàn)樗罉?shù)腐爛的營(yíng)養(yǎng)是對(duì)未來(lái)生長(zhǎng)的樹(shù)非常必要的。相反的 R 卻覺(jué)得移除死樹(shù)能迅速空出地方讓新樹(shù)生長(zhǎng)，這樣無(wú)疑會(huì)失敗。
　　此段結(jié)構(gòu)：
　　此段為總分結(jié)構(gòu)。一句陳述 L 的觀點(diǎn)和證據(jù)，然后表明相反態(tài)度后，又陳述了一遍 R 的觀點(diǎn)

　　Paragraph 3
　　Second, the lecturer argues that some insects and birds that inhabit dead trees are beneficial for tree growth. Some others that are thought to be harmful have shown no evidence of causing significant damage to the forest. By eliminating both harmful and beneficial birds and insects, salvage logging may cause unwanted damage to the forest in the long run. The reading, however, mentions only harmful insects, the spruce bark beetle in particular. It points out that because clearing the forest of dead trees also destroys the habitat of these harmful insects, it ensures the healthy recovery of a forest after fires.

　　此段功能：
　　第二個(gè)分論點(diǎn)中，作者先引出 L 的結(jié)論，適當(dāng)?shù)木幼∮谒罉?shù)的昆蟲(chóng)和鳥(niǎo)類是對(duì)森林有益的。

        一些認(rèn)為有害的昆蟲(chóng)其實(shí)并沒(méi)造成一些顯著的蟲(chóng)害。如果靠移除死樹(shù)把有益和有害鳥(niǎo)類昆蟲(chóng)
　　都?xì)⑺罆?huì)造成非預(yù)期的長(zhǎng)期損失。接著作者開(kāi)始說(shuō) R 只注意到了害蟲(chóng)，認(rèn)為移除一種特定的
　　甲蟲(chóng)就能保證森林恢復(fù)。
　　此段結(jié)構(gòu)：
　　此段為分分結(jié)構(gòu)，作者列出 L 的結(jié)論和證據(jù)后，只輕易的對(duì)比了 R 的結(jié)論和證據(jù)，但是讀者
　　能感覺(jué)到 R 的證據(jù)的片面，結(jié)論的草率。使 R 在相比之下顯得十分幼稚。

　　Paragraph 4
　　Finally with regard to economic impact, the lecturer argues against salvage logging because the dead trees can only be salvaged at a very high cost. Additionally, the employment opportunities associated with salvage logging are often temporary and are typically performed by non‐native residents. On the other hand, the reading argues that this practice provides many industries with the wood necessary to sustain production and even offers employment opportunities to local people.

　　此段功能：
　　在末尾一點(diǎn)經(jīng)濟(jì)影響的爭(zhēng)論下。L覺(jué)得這種移除死樹(shù)的策略是需要付出十分高的代價(jià)的，而且
　　所謂的工作機(jī)會(huì)也只是暫時(shí)性的，而且通?？拷?jīng)驗(yàn)者而不是當(dāng)?shù)厝司湍芙鉀Q的。對(duì)比起來(lái)，R只說(shuō)死樹(shù)給工業(yè)提供了原料，并且提供了工作機(jī)會(huì)。
　　此段結(jié)構(gòu)：
　　分分結(jié)構(gòu)，L 還是用證據(jù)陳列，直接壓倒了 R 陳列的非常不足的證據(jù)。

　　三、范文全篇總評(píng)
       1、 邏輯結(jié)構(gòu)
　　全文遵從總分結(jié)構(gòu)，開(kāi)頭段直一句話表明了強(qiáng)烈的反對(duì)邏輯和總結(jié)了爭(zhēng)吵的政策。
　　隨后作者只是詳細(xì)的羅列了 L 的證據(jù)和論點(diǎn)，甚至沒(méi)有說(shuō) R 是錯(cuò)的。但是把 R 的證據(jù)和結(jié)論
　　在 L 之后一重復(fù)，大家就看出 R 的證據(jù)也不完整，結(jié)論也很粗率，實(shí)在是不堪一擊。
　　2、語(yǔ)言表達(dá)
　　文中并沒(méi)有使用很多生僻詞匯，但是段式十分漂亮，可以借鑒的詞句有：
　　1. The lecturer and the reading passage hold completely different views toward(某政策), which is
　　the (進(jìn)一步解釋政策).
　　2. The reading, however, mentions only…(觀點(diǎn)和證據(jù))
　　在一大堆詳細(xì)的 L 證據(jù)下，R 僅羅列了某證據(jù)，對(duì)比之下清晰的可以看出 R 的不足。
