理了2024年12月英語四級閱讀理解模擬：泰國大象的生存危機，一起來看看吧。 2024年12月英語四級閱讀理解模擬：泰國大象的生存危機 For centuries, in the countries of south and Southeast Asia the elephant has been an intimate part of the culture, economy and religion, and nowhere more so than in Thailand. Unlike its African cousin, the Asian elephant is easily domesticated (馴化). The rare so-called white elephants have actually lent the authority of kingship to its rulers and until the 1920s the national flag was a white elephant on a red background.To the early Western visitors the country's romantic name was “Land of the White Elephant”. Today, however, the story is very different. Out of work and out of land, the Thai elephant struggles for survival in a nation that no longer needs it. The elephant has found itself more or less abandoned by previous owners who have moved on to a different economic world and a westernized society. And while the elephant's problems began many years ago, now it rates a very low national priority. How this reversal from national icon (圣像) to neglected animal came about is a tale of worsening environmental and the changing lives of the Thais themselves. According to Richard Lair, Thailand’s experts on the Asian elephant and author of the report Gone Astray, at the turn of the century there may well have beenas many as 100,000 domestic elephants in the country. In the north of Thailand alone it was estimated that more than 20,000 elephants were employed in transport, 1,000 of them alone on the road between the cities of Chiang Mai and Chiang Saen. This was at a time when 90 per cent of Thailand was still forest—a habitat (棲息地) that not only supported the animals but also made them necessary to carry goods and people. Nothing ploughs through dense forest better than a massive but sure-footed elephant. By 1950 the elephant population had dropped to a still substantial 13,397, but today there are probably nomore than 3,800, with another 1,350 roaming free in the national parks. But now, Thailand’s forest coversonly 20 per cent of the land. This deforestation (采伐森林) is the central point of the elephant's difficult situation, for it has effectively put the animals out of work. This century, as the road network grew, so the elephant's role as a beast of burden declined. 練習(xí)題： Choose correct answers to the question: 1.

Population growth rate 作為人口大國，我國很重視Population growth rate（人口增長率）。 它是反映人口發(fā)展速度和制定人口計劃的重要指標(biāo)，也是計劃生育統(tǒng)計中的一個重要指標(biāo)。人口的力量正在把世界分成兩部分：人口增長緩慢的地區(qū)，生活條件正在得到改善；人口增長迅速的地區(qū)，生活條件正在惡化。 我們來看2個例句： Obviously, Asia is a continent where the population growth rate was the highest in the world in the 20th century, which

當(dāng)做筆記： 講座文章篇幅較長，信息含量大，同學(xué)們也要適當(dāng)做一些筆記，抓住上面所提到的提示詞前后的關(guān)鍵信息和關(guān)鍵詞匯即可，運用簡寫、符號等縮短筆記時間。 在每個選項后面標(biāo)注它指定的內(nèi)容，比如時間，地點，人名或相關(guān)事件。在明白每個選項所指后，最后看問題問什么就可以輕松的選出來。 不要為了記筆記而記！注意力要更多地用來理解！ 同學(xué)們考試加油！ ?屠皓民領(lǐng)銜 四六級通關(guān)神器? ??????基礎(chǔ)班·沖刺押題班·白金班 直播錄播相結(jié)合，基礎(chǔ)強化沖刺全包括 ??不同水平，靈活選擇班型 $課程限時優(yōu)惠6折起$ 【基礎(chǔ)班

The government is about to allow universities to charge students up to $3,000 a year for their degrees, arguing that it’s a small price to pay compared with the financial rewards graduates reap later in life. But Prof. Walker’s research shows there are sharp variations in returns according to which subject a student takes. Law, medicine and economics or business are the most lucrative choices, making their average earnings 25% higher, according to the article, published in the office for national statistics’monthly journal. Scientists get 10-15% extra. At the bottom of the list are arts subjects, which make only a “small ”differenceto earnings- a small negative one, in fact. Just ahead are degrees in education-which leave hard pressed teachers anaverage of 5% better off a year than if they had left school at 18. “it’s hard to resist the conclusion that what students learn does matter a lot; and some subject areas givemore modest financial returns than others,” Prof. Walker said. As an economist, he was quick to point outthat students might gain non-financial returns from arts degrees:”Studying economics might be very dull, forexample, and studying post-modernism might be a lot of fun.” 練習(xí)題： Choose correct answers to the question: 1.What is the best title for the passage? A.Professor Walker’s Research B.How to Make Big Money. C.Differences Between Science and Arts Degrees. D.Studying Arts Has Negative Financial Outcome. 2.Universities charge students a rather high tuition mainly because_____ provide the students with very prosperous subjects to learn assume that their graduates can earn much more than they had paid don’t get financial support from the government need much revenue to support the educational expenses 3.The word “l(fā)ucrative”(Line 1, Para. 4) most probably means _____ le ve able le 4.Law, medical and business graduates could earn 25% more than ______ ion graduates graduates who had not studied at the university average income 5.We can safely conclude that the author ______ s arts degrees as meaningless this result disappointing and unfair the students to think twice before they decide what to learn in college that arts degrees are still rewarding despite its scarce financial returns 參考答案： 1.[D] 主旨大意題。本文為Walker教授的研究成果，旨在說明不同專業(yè)的畢業(yè)生有不同的經(jīng)濟回報，并非要傳授發(fā)財心得或者比較文理科的異同。文章首句即為本題解題關(guān)鍵，故D正確。 2.[B] 事實細節(jié)題。定位至第3段第1句。本文只有這一句與收取學(xué)費有關(guān)，后一個分句即前一個分句的理由，抓住其中隱含的因果關(guān)系就不難找到正確答案。 3.[C] 詞義理解題。通過下文數(shù)據(jù)earnings 25% higher和get 10-15% extra可以推測lucrative大意應(yīng)為“給人帶來豐厚收入的”,故選C。 4.[C] 事實細節(jié)題。第4段中出現(xiàn)了幾個比較數(shù)字，考題要求找到此段首句提到的收人增加25%的參照點。第2段第1句中的Getting through university 表明這類學(xué)生收人增加25%的參照對象是沒讀大學(xué)的人，且從第4段第3句中的the list和第4句即可以確定這一段是在比較大學(xué)畢業(yè)與18歲畢業(yè)(即沒讀大學(xué))收入的不同，因此C正確。 5.[D] 推理判斷題。結(jié)論往往出現(xiàn)在文章結(jié)尾,要想答對此題,一定要仔細體會本文末句。本文雖然重點討論文科沒有經(jīng)濟效益，但是作者并沒有做出主觀判斷，故A、B、C都不正確，而作者在文章最后講到了人文學(xué)科雖然經(jīng)濟效益不佳但學(xué)習(xí)過程更有趣，故D符合作者意思。 以上就是關(guān)于“2024年12月英語四級閱讀理解模擬：大學(xué)專業(yè)選擇”的全部內(nèi)容啦，祝同學(xué)們考試順利。
