托福官方真題Official8閱讀長難句Official8: The Rise of Teotihuacan

1. Among the main factors are Teotihuacán’s geographic location on a natural trade route to the south and east of the Valley of Mexico, the obsidian resources in the Teotihuacán Valley itself, and the valley’s potential for extensive irrigation.

2. The exact role of other factors is much more difficult to pinpoint―for instance, Teotihuacán’s religious significance as a shrine, the historical situation in and around the Valley of Mexico toward the end of the first millennium B.C., the ingenuity and foresightedness of Teotihuacán’s elite, and, finally, the impact of natural disasters, such as the volcanic eruptions of the late first millennium B.C.

3. The hard volcanic stone was a resource that had been in great demand for many years, at least since the rise of the Olmecs (a people who flourished between 1200 and 400 B.C.), and it apparently had a secure market.

Official8: Extinction of the Dinosaurs

1. Critics also point out that the shallow seaways had retreated from and advanced on the continents numerous times during the Mesozoic, so why did the dinosaurs survive the climatic changes associated with the earlier fluctuations but not with this one?

2. Scientists felt that they could get an idea of how long the extinctions took by determining how long it took to deposit this one centimeter of clay and they thought they could determine the time it took to deposit the clay by determining the amount of the element iridium (Ir) it contained.

3. Their calculations show that the impact kicked up a dust cloud that cut off sunlight for several months, inhibiting photosynthesis in plants; decreased surface temperatures on continents to below freezing; caused extreme episodes of acid rain; and significantly raised long-term global temperatures through the greenhouse effect.

Official8: Running water on Mars

1. The onrushing water arising from these flash floods likely also formed the odd teardrop-shaped “islands” (resembling the miniature versions seen in the wet sand of our beaches at low tide) that have been found on the plains close to the ends of the outflow channels.

2. Judging from the width and depth of the channels, the flow rates must have been truly enormous—perhaps as much as a hundred times greater than the 105 tons per second carried by the great Amazon river.

3. A 2003 Mars Global Surveyor image shows what mission specialists think may be a delta—a fan-shaped network of channels and sediments where a river once flowed into a larger body of water, in this case a lake filling a crater in the southern highlands.

4. But detractors maintain that the terraces could also have been created by geological activity, perhaps related to the geologic forces that depressed the Northern Hemisphere far below the level of the south, in which case they have nothing whatever to do with Martian water.

5. Furthermore, Mars Global Surveyor data released in 2003 seem to indicate that the Martian surface contains too few carbonate rock layers—layers containing compounds of carbon and oxygen—that should have been formed in abundance in an ancient ocean.

6. Aside from some small-scale gullies (channels) found since 2000, which are inconclusive, astronomers have no direct evidence for liquid water anywhere on the surface of Mars today, and the amount of water vapor in the Martian atmosphere is tiny.

在備戰(zhàn)托?？荚嚨倪^程中,，長難句往往成為考生們的一大難題。理解和分析這些復(fù)雜句子不僅需要扎實(shí)的語法基礎(chǔ),，還需要一定的技巧,。本文將分享一些關(guān)于如何攻克托福長難句的實(shí)用經(jīng)驗(yàn)，希望能幫助到每位考生,！??

1. 理解句子的結(jié)構(gòu)

首先,，面對一個長難句，最重要的是要理解其基本結(jié)構(gòu),。通常,，長難句由多個從句、短語組成,?？忌梢試L試將句子拆分成幾個部分，逐一分析,。比如,，考慮以下句子：

Although the theory was initially met with skepticism, subsequent research has provided substantial evidence supporting its validity.

在這個句子中，“Although”引導(dǎo)了一個讓步狀語從句,，而“subsequent research”是主句的主語,。理解這些關(guān)系,，可以幫助你更清晰地把握句意。

2. 學(xué)會識別信號詞

句子中的信號詞往往能幫助我們快速理解句子的邏輯關(guān)系,。例如：

• 因果關(guān)系：because, since, therefore
• 對比關(guān)系：however, on the other hand, whereas
• 遞進(jìn)關(guān)系：moreover, in addition, furthermore

通過識別這些信號詞,，考生可以更有效地理清句子的脈絡(luò)，從而提高理解能力,。??

3. 擴(kuò)充詞匯量

豐富的詞匯量是理解長難句的基礎(chǔ),。考生可以通過閱讀各種英文材料來增強(qiáng)詞匯量,，特別是學(xué)術(shù)類文章,。推薦閱讀一些經(jīng)典的托福閱讀材料，比如：

“The Impact of Climate Change on Biodiversity”

在閱讀時,，可以記錄不熟悉的單詞并進(jìn)行查閱,，逐步積累自己的詞匯庫。??

4. 練習(xí)長難句解析

多做一些長難句的解析練習(xí)也是非常重要的,?？梢赃x擇一些托福閱讀中的長難句進(jìn)行分析，嘗試回答以下問題：

• 句子的主干是什么,？
• 有哪些修飾成分,？
• 句子表達(dá)的主要觀點(diǎn)是什么？

例如,，分析句子：

Despite the challenges posed by technological advancements, educators have found innovative ways to engage students in the learning process.

通過這樣的方法,，考生可以培養(yǎng)自己的句子分析能力。??

5. 模擬考試環(huán)境

最后,，考生可以通過模擬考試來檢驗(yàn)自己的長難句理解能力,。在模擬考試中，盡量保持真實(shí)考試的時間限制和壓力,，這樣可以更好地適應(yīng)正式考試的節(jié)奏,。可以使用一些托福真題,，如：

“Reading Comprehension Practice Test”

在完成模擬測試后,，認(rèn)真分析錯題，尤其是長難句部分,，以便找到自己的薄弱環(huán)節(jié),。??

總之，攻克托福長難句的關(guān)鍵在于理解句子結(jié)構(gòu),、識別信號詞,、擴(kuò)充詞匯量、練習(xí)解析以及模擬考試,。希望這些經(jīng)驗(yàn)?zāi)軌驇椭忌鷤冊谕懈,？荚囍腥〉美硐氲某煽?！加油??
