揭秘托福閱讀的大坑貨：地質(zhì)時(shí)期

TPO 里面有一篇閱讀文章的開頭是這么寫的：

Paleozoic Era 334 to 248 million years ago

Mesozoic Era 245 to 65 million years ago

—Triassic Period

—Jurassic Period

—Cretaceous Period

Cenozoic Era 65 million years ago to the present

想必大家第一反應(yīng)是崩潰的，這都是什么鬼?What the heck?

一個(gè)不幸的消息是出現(xiàn)這些詞的托福文章還不少。雖然托福是考查大家的英語語言能力水平，但是了解托福?？紝W(xué)科的背景知識(shí)，可以幫助大家更快地熟悉閱讀乃至聽力里面的內(nèi)容。

今天V醬請(qǐng)來了朗播網(wǎng)的王宜涵老師，帶大家了解一下這些單詞背后到底指的什么和它們背后的故事

前面超復(fù)雜的英文翻譯其實(shí)是這樣的：

古生代(從 3 億 3 千 4 百萬年前到 2 億 4 千 8 百萬年前)

中生代(從 2 億 4 千 5 百萬年前到 6 千 5 百萬年前)

—三疊紀(jì)時(shí)期

—侏羅紀(jì)時(shí)期

—白堊紀(jì)時(shí)期

新生代 (從 6 千 5 百萬年前到現(xiàn)在)

在地質(zhì)學(xué)和考古學(xué)中，地質(zhì)年代 是用來描述地球歷史事件的時(shí)間單位。其中最大的時(shí)間單位是宙/元(eon)，宙下是代(era)，代下分紀(jì)(period)，紀(jì)下分世(epoch)，世下分期(age)。 如下圖所示。

一 | Paleozoic Era 古生代

古生代意為遠(yuǎn)古的生物時(shí)代，持續(xù)約 3 億年。對(duì)動(dòng)物界來說，這是一個(gè)重要時(shí)期。它以一場至今不能完全解釋清楚的進(jìn)化拉開了寒武紀(jì)的序幕。

寒武紀(jì)動(dòng)物的活動(dòng)范圍只限于海洋，但在古生代的廷續(xù)下，有些動(dòng)物的活動(dòng)轉(zhuǎn)向干燥的陸地。古生代后期，爬行動(dòng)物和類似哺乳動(dòng)物的動(dòng)物出現(xiàn)，古生代以迄今所知最大的一次生物絕滅宣吿完結(jié)。

★ Cambrian Period 寒武紀(jì)

寒武紀(jì)距今約 5 億 4 千 1 百萬年前 — 4 億 8 千 8 百萬年。這個(gè)名字來自于英國威爾士一個(gè)古代地名的羅馬名稱“Cambria”，該地的寒武紀(jì)地層被最早研究。中文名稱源自舊時(shí)日本人使用日語漢字音讀的音譯名“寒武紀(jì)”。

寒武紀(jì)距今十分久遠(yuǎn)，人們對(duì)當(dāng)時(shí)的地貌幾乎一無所知。只知當(dāng)時(shí)的大陸由一塊主要大陸的和幾塊較小的組成，當(dāng)時(shí)的動(dòng)物都生活在海洋。

寒武紀(jì)時(shí)期氣候溫暖，海平面升高，淹沒了大片的低洼地。這種淺海地帶為新的物種誕生創(chuàng)造了極為有利的條件，產(chǎn)生了一批具有堅(jiān)硬的貝殼或內(nèi)骨骼的動(dòng)物。它們很容易形成化石，因此和以前的軟體動(dòng)物不同，寒武紀(jì)動(dòng)物留下了大量遺體。

托福曾經(jīng)就考過 Cambrian Explosion 寒武紀(jì)大爆炸。

Animals originated relatively late in the history of Earth—in only the last 10 percent of Earth’s history. During a geologically brief 100-million-year period, all modern animal groups (along with other animals that are now extinct) evolved. This rapid origin and diversification of animals is often referred to as “the Cambrian explosion.”

Excerpt from TPO 6 Reading

是不是現(xiàn)在讀起來更順滑了一些?

此外，寒武紀(jì)是單細(xì)胞生物變?yōu)槎嗉?xì)胞生物的時(shí)期，有一個(gè)非常出名的動(dòng)物在此時(shí)期出現(xiàn)：Trilobite 三葉蟲。

三葉蟲是非常知名的化石動(dòng)物，其知名度可能僅次于恐龍。大多數(shù)三葉蟲是結(jié)構(gòu)簡單、體型微小的海生動(dòng)物，它們?cè)诤５着佬?，通過過濾泥沙來吸取營養(yǎng)。它們身體分節(jié)，有帶溝將身體分為三個(gè)垂直的葉。

(V醬看著這個(gè)化石瑟瑟發(fā)抖

)

托福閱讀中出現(xiàn)過三葉蟲的蹤跡：

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.

Excerpt from TPO 30 Reading

這回終于知道三葉蟲是什么鬼了。

二 | Mesozoic Era 中生代

中生代最早是由意大利地質(zhì)學(xué)家 Giovanni Arduino 所建立，在希臘文中，中生代意為“中間的”+“生物”。中生代介于古生代與新生代之間，可分為三疊紀(jì)，侏羅紀(jì)和白堊紀(jì)三個(gè)紀(jì)。

由于這段時(shí)期的優(yōu)勢動(dòng)物是爬行動(dòng)物，尤其是恐龍，因此又稱為爬行動(dòng)物時(shí)代(Age of the Reptiles)。中生代的氣候非常溫暖，對(duì)動(dòng)物的演化產(chǎn)生影響。在中生代末期，已見現(xiàn)代生物的雛形。

★ Triassic Period 三疊紀(jì)

三疊紀(jì)是 2.5 億至 2 億年前的一個(gè)地質(zhì)時(shí)代，它位于二疊紀(jì)和侏羅紀(jì)之間，是中生代的第一個(gè)紀(jì)。 這一時(shí)期最出名的應(yīng)該就是盤古大陸(Pangea)了，考古學(xué)家認(rèn)為這一時(shí)期地球上的陸地都是連接在一起的，直到侏羅紀(jì)末期陸地才開始漂移，彼此分開。

★ Jurassic Period 侏羅紀(jì)

侏羅紀(jì)(1 億 9960 萬年前到 1 億 4550 萬年前)界于三疊紀(jì)和白堊紀(jì)之間，是中生代的第二個(gè)紀(jì)。

侏羅紀(jì)前期，因?yàn)榻?jīng)歷大滅絕，所以各種動(dòng)植物都非常稀少，不過恐龍伺機(jī)稱霸陸地。侏羅紀(jì)中晚期以后，恐龍成為地球上最繁榮昌盛的優(yōu)勢物種，此后統(tǒng)治地球長達(dá) 1.5 億年。

ETS 可能覺得大家對(duì)侏羅紀(jì)非常的熟悉，所以托福很少涉及到這一時(shí)期的內(nèi)容。但偶爾，侏羅紀(jì)還是會(huì)冒出來刷一波存在感，在 TPO 6 的閱讀文章中就曾經(jīng)考查過相關(guān)內(nèi)容。

Limestone may be found in the Cambrian or—300 million years later—in the Jurassic strata, but a trilobite—the ubiquitous marine arthropod that had its birth in the Cambrian—will never be found in Jurassic strata, nor a dinosaur in the Cambrian.

Excerpt from TPO 6 Reading

這一句話不僅有 Jurassic，還有前面提到的 Cambrian 和 trilobite，emmmmm，出題人還真是喜歡寒武紀(jì)。

★ Cretaceous Period 白堊紀(jì)

白堊紀(jì)是中生代的最后一個(gè)紀(jì)，長達(dá) 8000 萬年，因歐洲西部該年代的地層主要為白堊沉積而得名。白堊紀(jì)的氣候相當(dāng)暖和，是恐龍最興盛的時(shí)期，托福中經(jīng)常提到的恐龍都是出自白堊紀(jì)。

舉個(gè)栗子：綜合寫作中出現(xiàn)過的Tyrannosaurus(簡稱 T—rex)也就是霸王龍，相信不少同學(xué)剛聽到的時(shí)候腦子是懵懵的。 What the hell?

我們來看一篇 TPO 閱讀里面的節(jié)選片段：

Data from diverse sources, including geochemical evidence preserved in seafloor sediments, indicate that the Late Cretaceous climate was milder than today’s.

The days were not too hot, nor the nights too cold. The summers were not too warm, nor the winters too frigid. The shallow seas on the continents probably buffered the temperature of the nearby air, keeping it relatively constant.

Excerpt from TPO 8 Reading

現(xiàn)在結(jié)合白堊紀(jì)的背景，讀起來是不是沒有理解上的障礙了?

三 | Cenozoic Era 新生代

新生代是地球歷史上最新的一個(gè)地質(zhì)時(shí)代，它從 6600 萬年前開始一直持續(xù)到今天。

隨著恐龍的滅絕，中生代結(jié)束，新生代開始。新生代中，盤古大陸徹底分裂，地球上的各個(gè)大陸逐漸移動(dòng)到今天的位置上。

托福經(jīng)?？嫉氖沁@時(shí)期的“冰川時(shí)期 the Ice Age”，比如：

Eventually, Agassiz and others convinced geologists and the general public that a great continental glaciation had extended the polar ice caps far into regions that now enjoy temperate climates.

For the first time, people began to talk about ice ages. It was also apparent that the glaciation occurred in the relatively recent past because the drift was soft, like freshly deposited sediment. We now know the age of the glaciation accurately from radiometric dating of the carbon-14 in logs buried in the drift.

The drift of the last glaciation was deposited during one of the most recent epochs of geologic time, the Pleistocene, which lasted from 1.8 million to 10,000 years ago.

Excerpt from TPO 19 Reading

Pleistocene 為更新世，它是新生代下面的其中一個(gè)世。了解些許的背景，這段理解起來就沒有之前那么困難了，si 不 si?

大家讀到到這里，心里的 mmp 就出來了，托福閱讀就愛考這些奇奇怪怪、超難記的單詞，真想送一首《涼涼》給自己。

但現(xiàn)實(shí)是殘酷的，想拿到高分，還是需要大家認(rèn)真準(zhǔn)備。同時(shí)，如果學(xué)有余力還可以多多了解托福?？嫉脑掝}的背景知識(shí)，一來可以給自己長長見識(shí)，二來萬一托?？嫉搅?，嘴上可以笑嘻嘻喲。

零基礎(chǔ)如何搞定托福閱讀

今天，首先要聊的就是新托福閱讀。

當(dāng)我們從0基礎(chǔ)起步的時(shí)候，有一個(gè)特別應(yīng)該注意的關(guān)鍵性問題，就是一定不要試圖一開始就面面俱到!換句話說，我們?cè)跍?zhǔn)備托?？荚嚨臅r(shí)候，首先第一件事要做的，就是要先打開一個(gè)突破口，然后順勢而入，繼而攻克其他的幾個(gè)單項(xiàng)。這是首先一定要有的一個(gè)策略問題!

當(dāng)我們有這樣一個(gè)指導(dǎo)方針之后，首先第一步，象形各位考友都會(huì)非常心里有數(shù)的選擇背單詞了。在此特別提醒，一定要背2本單詞書：大學(xué)4級(jí)單詞+7天搞定托福單詞。很多人總是會(huì)誤解，認(rèn)為考托福考試，就只背托福單詞就好了，但是實(shí)際上，所有的托福單詞書都是默認(rèn)去掉大學(xué)4記單詞的，但是對(duì)于0基礎(chǔ)的考生，又恰巧是缺了這部分單詞，因此一定要背2部分單詞，分別是大學(xué)4級(jí)單詞與托福單詞。

第二步，語法。語法其實(shí)應(yīng)該被我們分為2個(gè)部分，第一個(gè)部分是基礎(chǔ)的語法知識(shí)，這個(gè)部分應(yīng)該參照《iBT新托福語法》系列，將這個(gè)部分的內(nèi)容進(jìn)行補(bǔ)齊。

但是這個(gè)僅僅是一部分，還有第二部分，也就是對(duì)于更基礎(chǔ)性的語法內(nèi)容，應(yīng)該首先讓各位考友先報(bào)露出自己的問題，然后再通過矯正的手段來解決問題。要想這么做最好的方法就是，先寫作文，然后再進(jìn)行批改，這種方法是最好的，一個(gè)發(fā)現(xiàn)問題，然后解決問題的手段。

第三步，長難句。其實(shí)，現(xiàn)在中國的英語教學(xué)是重學(xué)不重用，對(duì)，也就是不中用。英語考試的核心應(yīng)該是注重應(yīng)用和理解，但是中國的英語考試，由于各種各樣的原因，使得中國的英語考試就喜歡考察一些邊角廢料，最不常用的內(nèi)容。

反過來倒使得最關(guān)鍵的立即和應(yīng)用變成了配角，不得不說是一個(gè)天大的悲哀!分析托福閱讀長難句，其實(shí)最關(guān)鍵的目的就是要去讓自己快速的理解和整合句意，以達(dá)到快速解題的目的。

第四步，看美劇。尤其是要將中文字幕放在屏幕上面，英文字幕放在屏幕下面。這樣做的目的就是讓我們還原英語是一門語言的這個(gè)本質(zhì)，去多接觸英語怎么說，通過量變達(dá)到質(zhì)變，這一點(diǎn)尤其對(duì)于最后期望達(dá)到100分的考友來說，十分重要。

托福閱讀真題1

PASSAGE 69

Newspaper publishers in the United States have long been enthusiastic users and distributors of weather maps. Although some newspapers that had carried the United States Weather Bureau's national weather map in 1912 dropped it once the novelty had passed, many continued to print the daily weather chart provided by their local forecasting office. In the 1930's, when interest in aviation and progress in air-mass analysis made weather patterns more newsworthy, additional newspapers started or resumed the daily weather map. In 1935, The Associated Press (AP) news service inaugurated its WirePhoto network and offered subscribing newspapers morning and afternoon weather maps redrafted by the AP's Washington, B.C., office from charts provided by the government agency. Another news service, United Press International (UPI), developed a competing Photowire network and also provided timely weather maps for both morning and afternoon newspapers. After the United States government launched a series of weather satellites in 1966, both the AP and UPI offered cloud-cover photos obtained from the Weather Bureau.

In the late 1970's and early 1980's, the weather map became an essential ingredient in the redesign of the American newspaper. News publishers, threatened by increased competition from television for readers' attention, sought to package the news more conveniently and attractively. In 1982, many publishers felt threatened by the new USA Today, a national daily newspaper that used a page-wide, full-color weather map as its key design element. That the weather map in USA Today did not include information about weather fronts and pressures attests to the largely symbolic role it played. Nonetheless, competing local and metropolitan newspapers responded in a variety of ways. Most substituted full-color temperature maps for the standard weather maps, while others dropped the comparatively drab satellite photos or added regional forecast maps with pictorial symbols to indicate rainy, snowy, cloudy, or clear conditions. A few newspapers, notably The New York Times, adopted a highly informative yet less visually prominent weather map that was specially designed to explain an important recent or imminent weather event. Ironically, a newspaper's richest, most instructive weather maps often are comparatively small and inconspicuous.

托福閱讀真題2

The origins of nest-building remain obscure, but current observations of nest-building activities provide evidence of their evolution. Clues to this evolutionary process can be found in the activities of play and in the behavior and movements of birds during mating, such as incessant pulling at strips of vegetation or scraping of the soil. During the early days of the reproductive cycle, the birds seem only to play with the building materials. In preparation for mating, they engage in activities that resemble nest-building, and continue these activities throughout and even after the mating cycle. Effective attempts at construction occur only after mating.

Although nest-building is an instinctive ability, there is considerable adaptability in both site selection and use of materials, especially with those species which build quite elaborate constructions. Furthermore, some element of learning is often evident since younger birds do not build as well as their practiced elders. Young ravens, for example, first attempt to build with sticks of quite unsuitable size, while a jackdaw's first nest includes virtually any movable object. The novelist John Steinbeck recorded the contents of a young osprey nest built in his garden, which included three shirts, a bath towel, and one arrow.

Birds also display remarkable behavior in collecting building materials. Crows have been seen to tear off stout green twigs, and sparrowhawks will dive purposefully onto a branch until it snaps and then hang upside down to break it off. Golden eagles, over generations of work, construct enormous nests. One of these, examined after it had been dislodged by high winds, weighed almost two tons and included foundation branches almost two meters long. The carrying capacity of the eagles, however, is only relative to their size and most birds are able to carry an extra load of just over twenty percent of their body weight.

(A) interesting

(B) unclear

(C) imperfect

(D) complex

2. According to the passage , which of the following activities is characteristic of the early part of the reproductive cycle of birds?

(A) Selecting a mate

(B) Collecting nest-building materials

(C) Playing with nest-building materials

(D) Building a nest

3. The word display in line 17 is closest in meaning to

(A) communicate

(B) imitate

(C) initiate

(D) exhibit

4. The novelist John Steinbeck is mentioned in line 14 because he

(A) conducted a scientific study on the behavior of ospreys

(B) was the first to describe where ospreys built their nests

(C) described the materials ospreys can use to build their nests

(D) compared the size of osprey nests with the nests of other species

5. Which of the following birds are mentioned as those that build nests that include unusual

objects?
