六分：文章切題，闡說充分，文章有說服力;段落組織有序，銜接緊密，過渡自然，有很強的邏輯性;段落內(nèi)句與句連接順暢，句式使用恰當(dāng)，靈活，嫻熟;用詞確切，得體。文章中有個別語法拼寫錯誤，但不影響內(nèi)容表達。
五分：文章切題，闡說基本充分，在某些細節(jié)上有缺陷。段落層次組織有序，銜接緊密，過渡自然，邏輯性強;句間連接順暢，句式使用恰當(dāng)，靈活;用詞基本得體。文章中有少量用詞不當(dāng)和語法拼寫錯誤。
四分：文章切題，闡說尚可，展開不夠。段落層次組織有序，銜接緊密，過渡自然，有邏輯性;句間連接基本順暢;有部分句法錯誤;用詞一般，有時不得體。詞性區(qū)分和拼寫等有若干錯誤。
三分：文章切題，段落組織基本合理，有邏輯性，但只存在于語義層次上，語言表達上未能體現(xiàn);句子框架結(jié)構(gòu)基本成立，但有許多語法錯誤，句間聯(lián)系不順暢，往往是不善于使用邏輯連詞，顯得幼稚，生硬。詞匯方面拼寫錯誤多，常有用詞不得體現(xiàn)象。
二分：文章切題。闡說沒有展開，只限于三言兩語地回答問題;沒有段落組織，很亂，長度很短，只有一段;句子排列有一定的邏輯關(guān)系，能看出各句基本框架，但結(jié)構(gòu)或語法錯誤較多;用詞不得體，拼寫錯誤多。
一分：文章各方面都有嚴(yán)重錯誤，句子不像句子?？傮w印象是根本沒有寫作能力，英語水平太低，夠不上二分標(biāo)準(zhǔn)，只能打最低分。

托福閱讀TPO30第2篇:The Pace of Evolutionary Change
【1】A heated debate has enlivened recent studies of evolution. Darwin's original thesis, and the viewpoint supported by evolutionary gradualists, is that species change continuously but slowly and in small increments. Such changes are all but invisible over the short time scale of modern observations, and, it is argued, they are usually obscured by innumerable gaps in the imperfect fossil record. Gradualism, with its stress on the slow pace of change, is a comforting position, repeated over and over again in generations of textbooks. By the early twentieth century, the question about the rate of evolution had been answered in favor of gradualism to most biologists' satisfaction.
【2】Sometimes a closed question must be reopened as new evidence or new arguments based on old evidence come to light. In 1972 paleontologist Stephen Jay Gould and Niles Eldredge challenged conventional wisdom with an opposing viewpoint, the punctuated equilibrium hypothesis, which posits that species give rise to new species in relatively sudden bursts, without a lengthy transition period. These episodes of rapid evolution are separated by relatively long static spans during which a species may hardly change at all.
【3】The punctuated equilibrium hypothesis attempts to explain a curious feature of the fossil record—one that has been familiar to paleontologist for more than a century but has usually been ignored. Many species appear to remain unchanged in the fossil record for millions of years—a situation that seems to be at odds with Darwin's model of continuous change. Intermediated fossil forms, predicted by gradualism, are typically lacking. In most localities a given species of clam or coral persists essentially unchanged throughout a thick formation of rock, only to be replaced suddenly by a new and different species.
【4】The evolution of North American horse, which was once presented as a classic textbook example of gradual evolution, is now providing equally compelling evidence for punctuated equilibrium. A convincing 50-million-year sequence of modern horse ancestors—each slightly larger, with more complex teeth, a longer face, and a more prominent central toe—seemed to provide strong support for Darwin's contention that species evolve gradually. But close examination of those fossil deposits now reveals a somewhat different story. Horses evolved in discrete steps, each of which persisted almost unchanged for millions of years and was eventually replaced by a distinctive newer model. The four-toed Eohippus preceded the three-toed Miohippus, for example, but North American fossil evidence suggests a jerky, uneven transition between the two. If evolution had been a continuous, gradual process, one might expect that almost every fossil specimen would be slightly different from every year.
【5】If it seems difficult to conceive how major changes could occur rapidly, consider this: an alteration of a single gene in files is enough to turn a normal fly with a single pair of wings into one that has two pairs of wings.
【6】The question about the rate of evolution must now be turned around: does evolution ever proceed gradually, or does it always occur in short bursts? Detailed field studies of thick rock formations containing fossils provide the best potential tests of the competing theories.
【7】Occasionally, a sequence of fossil-rich layers of rock permits a comprehensive look at one type of organism over a long period of time. For example, Peter Sheldon's studies of trilobites, a now extinct marine animal with a segmented body, offer a detailed glimpse into three million years of evolution in one marine environment. In that study, each of eight different trilobite species was observed to undergo a gradual change in the number of segments—typically an increase of one or two segments over the whole time interval. No significant discontinuous were observed, leading Sheldon to conclude that environmental conditions were quite stable during the period he examined.
【8】Similar exhaustive studies are required for many different kinds of organisms from many different periods. Most researchers expect to find that both modes of transition from one species to another are at work in evolution. Slow, continuous change may be the norm during periods of environmental stability, while rapid evolution of new species occurs during periods of environment stress. But a lot more studies like Sheldon's are needed before we can say for sure.

托福閱讀答案
1.innumerable是不可計數(shù)的，A是無數(shù)的，B是偶然的，C是大的，D是重復(fù)的。這個單詞是numerable加否定前綴，很容易就能推出意思來。
2.A答案對應(yīng)第一段第二句， B對應(yīng)第一段第三句，D對應(yīng)一段最后一句。C與原文沖突，原文一直在說darwin理論被人們廣泛接受。
3.高亮句子的主干部分是斷點平衡論挑戰(zhàn)了原來的漸進論，然后解釋了斷點平衡論的內(nèi)容。A選項which修飾不明，容易產(chǎn)生誤解;B選項與原文矛盾，C與原文不符，原文S和N的觀點是change的發(fā)生是without lengthy transition的。D和原文意思相符，并且也包含了所有的主干部分。
4.根據(jù)原文，漸進論是說物種演變是通過長時間的緩慢改變發(fā)生的;斷點平衡論是說物種演變是短期爆發(fā)的。所以選擇C，進化是否是勻速發(fā)生的。
5.根據(jù)lack of intermediate fossils定位到第三段倒數(shù)第二句，在往前看一句說，這一情況對于達爾文學(xué)說是不和的，而達爾文學(xué)說正是漸進論，這一段的最后也說原來的物種突然被替換，而不是漸漸進化改變的。所以C符合原文意思。 A與原文第一句破折號后矛盾，原文說這一現(xiàn)象一直被Ignored，B選項原文矛盾，該現(xiàn)象應(yīng)該是反對了達爾文學(xué)說，支持了物種有長期不改變的論點。D雖然正確但是只是本段的細節(jié)，不能表達主題，所以不選。
6.Compel本身是強迫，此處作為evidence的形容詞可以延伸為說服力強的。因此答案選B 有說服力的。A是驚奇的，C是有爭議的，D是細節(jié)的。都不沾邊。另外通過句義可以判斷，前文說馬的進化was once 是經(jīng)典的漸進論的證明，is now(輕微轉(zhuǎn)折)提了"equally"怎么樣的證據(jù)證明了點斷平衡論，前文既然說對gradual evolution很支持，那么后文出現(xiàn)equally，那應(yīng)該對點斷論也是有力證據(jù)。因此選B。
7.對應(yīng)部分在第四段的第二句和第五句，只有D選項沒有出現(xiàn)。
8.這一句話說一個怎么樣的單一基因就足以變一個普通飛禽的一對的正常翅為兩對翅膀，所以有推理應(yīng)該是要改變這個基因。所以選C，Alteration是修改，變更，A選項是不完美，B是替換，D是復(fù)制 帶入后都改變了原文的意思。
9.根據(jù)Peter Sheldon定位到原文第二句。后面對trilobites進行了描述，A選項對應(yīng)了原文第三句，后文又繼續(xù)說沒有明顯的斷點。所以A正確。 B與原文第四句沖突。C與第三句沖突，D原文沒有這種說法。而且上文也表明它符合gradual evolvement。
10.occasionally，是偶然偶爾的意思。A是毫無疑問的，B是基本上，C是偶爾有一次。D是在一定程度上。因此應(yīng)該選C。并且上文提出問題說是否有過逐漸進化?那么下文給的是一個逐漸進化的例子，所以應(yīng)該是在表達偶爾有一兩個的意思。
11.上文說實地勘測會給competing theories提供test，第七段就給了試驗例子，那么就證明是A正確。B與原文沖突，這個例子是支持漸進論的。C也不對，理由同上。D與原文目的不符。
12.首先句子開頭出現(xiàn)了They，那么我們應(yīng)該能在前文找到一個提到人物的地方，句子又提出environmental condition的作用，那么后文應(yīng)該會出現(xiàn)對這一理論的解釋，那么C是符合的，也可以進行代入驗證。
13.A斷點平衡論論點為物種變化發(fā)生突然，快速，符合。B對應(yīng)文章第一段第一句話，符合漸進論。C與原文第四段第二句矛盾，原文說馬進化會變大。不選。D原文第一段第一句，符合漸進論。E對應(yīng)原文第三段。符合點斷平衡論。F原文沒提到，不選。G原文最后一段，說漸進論應(yīng)該會是環(huán)境比較穩(wěn)定的情況下的進化規(guī)則。符合漸進論。
托福閱讀譯文
【1】最近的一個關(guān)于進化的研究引發(fā)了激烈的爭論。達爾文的原始論點和進化漸進主義者支持的觀點是物種會持續(xù)地改變，但非常緩慢，增量也很小。這種改變是普遍的，但是現(xiàn)在短時間的觀察是不能察覺的，并且，這個觀點聲稱，它們通常被掩蓋于不完美的化石記錄的不可計數(shù)的缺失中。漸進主義及其對物種緩慢變化的引力讓人欣然接受，并在世代的教科書中重復(fù)出現(xiàn)。在20世紀(jì)早前之前，令大部分的生物學(xué)家滿足于利用漸進主義來回答關(guān)于進化速率的問題。
【2】有時，已經(jīng)有了結(jié)論的問題必須由在已有證據(jù)基礎(chǔ)上出現(xiàn)的新的證據(jù)和新的論點使其重新展開討論。在1972年，古生物學(xué)者Stephen Jay Gould和 Niles Eldredge用相反的論點挑戰(zhàn)了世俗的結(jié)論，即斷點平衡說，它假設(shè)了物種演變?yōu)樾碌奈锓N是通過相對突然的爆發(fā)，并非通過長時間的過渡時期。迅速的進化期被時間相對更長的靜態(tài)期分開，而在靜態(tài)時期，物種是幾乎完全不變的。
【3】斷點平衡論試著去解釋化石記錄的一個古怪的特點----在超過一個世紀(jì)的時間里它已經(jīng)為古生物學(xué)者所熟悉，但一直被忽視。許多物種似乎在上百萬年的化石記錄中一直沒有改變，這個情況與達爾文的模型所支持的物種的持續(xù)變化相悖。進化漸進論的支持者所預(yù)測的中間狀態(tài)的化石一直沒有出現(xiàn)。在大部分蛤和珊瑚的聚集地，其化石在很厚的巖石中都實際上沒有變化，只是突然被另一新的并且不同的物種而取代。
【4】北美馬的進化曾經(jīng)被用作經(jīng)典的教科書案例來證明漸變進化論，現(xiàn)在卻為斷點平衡學(xué)提供了同樣有說服力的證據(jù)。一個有說服力的5千萬年的馬祖先的進化模型----每一代都稍稍大一點，有更復(fù)雜的牙齒，更長的臉，和中間更突出的腳趾----這一切都看似強有力的支持了達爾文的論點，物種是逐步地進化的。但是，對這些化石更嚴(yán)謹?shù)尿炞C現(xiàn)在揭示了一個不太一樣的故事。馬是在不連續(xù)的步驟中進化的，其中每個進化步驟中間都有上百萬年時間保持不變，在最后被一個不同的更新的模型取代。比如四只腳趾的Eohippus 在三只腳趾的moihippus之前，但北美化石證據(jù)表明在這之間有一個不平穩(wěn)的，不均衡的轉(zhuǎn)換過程。如果進化一直都是連續(xù)，漸進的過程，人們應(yīng)該預(yù)期到的是每年的化石樣本都會存在細微的差別。
【5】如果很難設(shè)想大的改變會迅速發(fā)生，想想這些：一個單一基因的改變就足以將有一對翅膀的蒼蠅變成兩對翅膀。
【6】關(guān)于進化速度的問題現(xiàn)在發(fā)生了轉(zhuǎn)變：進化過程是逐漸發(fā)生的么，還是總是突然短時間的爆發(fā)?對含有化石的厚巖層的細致的現(xiàn)場調(diào)查可以檢驗這兩個備受爭論的理論。
【7】偶爾，有一個系列的化石豐富的巖石可以允許人們綜合性的觀察一種生物在很長一段時間中的變化。比如，Peter Sheldon對于三葉蟲，一種已滅絕的身體分節(jié)的海洋生物，的研究提供了其對三百萬年來在同一海洋環(huán)境下進化的一些細節(jié)。研究中，八種三葉蟲都觀察到了其身體節(jié)數(shù)數(shù)量逐漸改變的過程，在整個時間段中，一般身體都增加了一到兩節(jié)。沒有明顯的不連貫，這使sheldon得出結(jié)論：海洋環(huán)境在那段時間是比較穩(wěn)定的。
【8】很多來自不同時期的不同的生物都需要開展相似的相近研究。大多數(shù)研究者希望發(fā)現(xiàn)物種進化的這兩種模式都存在。緩慢的，連續(xù)的變化可能是在環(huán)境穩(wěn)定的時間段下的規(guī)律，而快速進化的新物種則發(fā)生在環(huán)境變化時期的壓力下。但是，我們需要更多的想Sheldon所做的研究以證明這個觀點。
