雅思閱讀多選題的正確解題步驟
雅思閱讀多選題是閱讀里面較難的一種選擇題，因?yàn)樗拇鸢竿?~3個(gè)選項(xiàng)，下面小編給大家?guī)?lái)了讓雅思考官來(lái)教你雅思閱讀多選題的正確解題步驟，希望能夠幫助到大家，下面小編就和大家分享，來(lái)欣賞一下吧。
讓雅思考官來(lái)教你雅思閱讀多選題的正確解題步驟
接下來(lái)，讓雅思考官來(lái)教你正確的解題步驟：
1. Read the question and underline the "keywords" - these are the words that you will try to find in the passage (the main words that give the meaning of the question).
讀題并劃出關(guān)鍵詞，就是你即將要去文章中找的能體現(xiàn)題目含義的詞語(yǔ)
2. Read the choices and underline one or two keywords for each one. Focus on words that make the difference between each choice.
讀選項(xiàng)，每個(gè)劃出一兩個(gè)關(guān)鍵詞。仔細(xì)研究每個(gè)選項(xiàng)的差別
3. Go to the passage and look for the keywords from the question.
去文章找到問(wèn)題中的關(guān)鍵詞
4. When you have found the right part of the passage, look for keywords from the choices.
當(dāng)你找到答案段落，尋找選項(xiàng)中的關(guān)鍵詞
5. Read the relevant part of the passage carefully, comparing it to each choice.
仔細(xì)閱讀相關(guān)段落，和每個(gè)選項(xiàng)做比較
6. To be sure you have the right answer, you should be able to show that the other answer choices are wrong.
你確定你有正確答案的時(shí)候應(yīng)該能證明其它的是錯(cuò)的
以上是正確的解題步驟，再補(bǔ)充一些更加細(xì)節(jié)的技巧——如何判斷題點(diǎn)在原文中的位置。比如劍4-94頁(yè)的20-21題：The list below gives some statements about anthropology。Which TWO statements are mentioned by the writer of the text? 一看題目讓我們找anthropology相關(guān)的東西，翻回原文發(fā)現(xiàn)文章標(biāo)題是archeology，所以整篇文章肯定都在說(shuō)archeology，而我們要找的anthropology肯定只是其中集中講述的一個(gè)插曲段落。所以出題位置肯定相對(duì)集中，而且肯定明顯包含anthropology字樣。只需稍微瞟一眼整篇文章，很快就能發(fā)現(xiàn)，幾乎每一段的開(kāi)頭都是以archeology開(kāi)頭，唯一例外的是第4和5段，以anthropology開(kāi)頭。所以20-21肯定就在這兩段之內(nèi)。這是根據(jù)題干的關(guān)鍵詞來(lái)推測(cè)定位。
雅思閱讀真題解析--Researcher on the Tree Crown
Researcher on the Tree Crown(樹(shù)冠研究)
You should spend about 20 minutes on Question 14-26 which are based on Reading Passage below.
AThe forest canopy-the term given to the aggregated crowns of trees in a forest-is thought to host up to 40 per cent of all species, of which ten per cent could be unique to the forest roof. "We're dealing with the richest, least known, most threatened habitat on Earth," says Andrew Mitchell, the executive director of the Global Canopy Programme/ a collection of groups undertaking research into this lofty world. "The problem with our understanding of forests is that nearly all the information we have has been gleaned from just two meters above the soil, and yet we're dealing with trees that grow to heights of 60 meters, or in the case of the tallest redwood 112 meters. It's like doctors trying to treat humans by only looking at their feet."
BTropical rainforest comprises the richest of ecosystems, rivalled only by coral reel for its diversity and complex interrelationships. And a great deal of that diversity lives up in the canopy-an estimated 70-90 per cent of life in the rainforest exists in the trees; one in ten of all vascular plants are canopy dwellers; and about 20-25 per cent of all invertebrates are thought to be unique to the canopy.
CThe first Briton to actually get into the canopy may have been Sir Francis Drake who, in 1573, gained his first glimpse of the Pacific Ocean from a tall tree in Darien, Panama. However, the first serious effort to reach and study the canopy didn't begin until 1929. The Oxford University Expedition to British Guiana, led by Major RWG Hingston, still ended up help of locals when it came to building an observation platform. It was a successful expedition all the same, despite the colony's acting governor getting stuck high up on a winched seat during a visit. In terms of canopy access, the French have proved themselves to be excellent innovators, taking things further with the development of 'lighter-than-air platforms -balloons and related equipment, to you and me. Francis Halle; from the Laboratoire de Botanique Tropicale at Montpellier University took to a balloon in the mid-1980s in order to approach the canopy from above. His work in French Guiana was inspired by the use in Gabon of a tethered helium balloon by Marcel and Annette Hladick. Halle went one further by using a small purpose-built airship-a cigar-shaped balloon with propellers to aid manoeuvrability. "We suddenly had a mobile system that could move around the treetops; there was no other means of doing this," says Mitchell.
DFrom this, two balloon-dependent features have developed: the radeau or raft, and the luge or sledge. The raft is a 'floating' platform, employed by French academics Dany Cleyet-Marrel and Laurent Pyot and is essentially an island in the treetops. Made of kevlar mesh netting and edged with inflated neoprene tubes, it rests on top of the canopy, allowing sampling (mostly of plants and insects) to take place at the edges of the platform, and can stay in position for several days. The luge, on the other hand, is an inflated hexagon similar to a traditional balloon basket but with a hole in the bottom covered with Kevlar mesh. Such techniques aren't without their problems, however, "balloons can cover larger areas, especially for collection purposes, but they are extremely expensive- Jibe raft alone cost 122,000 [euro] (86,000 [pounds sterling]) in 2001], nut very effective because you can only reach the tops of the trees, and are highly dependent on the weather, " says Dr Wilfried Morawetz, director of systematic botany at the University of Leipzig. “Balloons can usually only be used in the early morning for two to four hours. Last time, we could only fly three times during a whole week." Given these factors, it comes as no surprise that operations involving these balloons numbered just six between 1986 and 2001.
ESmithsonian Tropical Research Institute in Panama. Smith had the idea of using a static crane to get into the treetops. Un-tethered balloons may allow widely distributed sites to be sampled, but cranes allow scientists to study an area of at least a hectare from soil to canopy throughout the year, year after year. "Cranes beat any other access mode. They are cheap, reliable and fast. In two minutes I can reach any point in our forest, which is essential for comparative measurements across species," says Professor Christian Korner of the University of Basel. Korner is using a static crane in a unique carbon dioxide-enrichment experiment in Switzerland, in an attempt to discover how forests might respond to the global increase in atmospheric carbon dioxide (see Swiss canopy-crane carbon experiment, right). For reasons of convenience, cranes are generally situated close to cities or a research center. Leipzig University has a crane not far from the town, the Location allowing scientists to study the effect of city pollutants on forests. In order to increase the amount of canopy a crane can access, some have been mounted on short rail tracks. In "1995, Dr Wilfried Morawetz was the first to use this technique, installing a crane on 150 meters of track in Venezuelan rainforest. “In my opinion, cranes should be the core of canopy research in the future," he says.
FIt appears that the rest of the scientific community has now come around to Mitchell's way of thinking. "I think most scientists thought him mad to consider such a complex field station at first," says internationally respected 'canopist' Meg Lowman, the executive director of the Marie Selby Botanical Gardens. "However, we've all come to realize that a combination of methods, a long-term approach to ecological studies and a collaborative approach are the absolute best ways to advance canopy science. A permanent canopy field station would allow that to happen." With A dedicated group of canopy scientists working together and a wide range of tools available for them to get into the treetops, we're now finally on our way towards a true understanding of the least-known terrestrial habitat.

樹(shù)冠的研究者
A
森林樹(shù)冠層是用來(lái)描述森林中所有樹(shù)冠總和的術(shù)語(yǔ)，是超過(guò)40%生物物種的棲息地，其中10%的物種是只生活在樹(shù)冠上的。Global Canopy Programme是專(zhuān)門(mén)研究樹(shù)冠的組織，它的執(zhí)行主席Andrew Mitchell說(shuō)道：“我們正在研究地球上最豐富，最鮮為人知但是 又最受威脅的棲息地。我們對(duì)森林認(rèn)識(shí)的問(wèn)題在于幾乎所有我們收集的信息只是從距離地面2米的地方獲得的，但是我們卻要以此研究關(guān)于距離地面60米髙的樹(shù)，或是最高達(dá)112米的紅木這樣的樹(shù)木的問(wèn)題。這就好比醫(yī)生只能通過(guò)看病人的腳來(lái)治愈病人?！?/p>
B
熱帶雨林包含最豐富的生態(tài)系統(tǒng)，從生物多樣性和生物之間關(guān)系的復(fù)雜性上來(lái)講，只有珊瑚礁可以與之媲美。而其中大部分的多樣性的生物都居住在樹(shù)冠上，據(jù)估計(jì)雨林中70%-90%的生物居住在樹(shù)上，有十分之一的導(dǎo)管植物是生長(zhǎng)在樹(shù)冠層，大約20%-25%的無(wú)脊椎動(dòng)物只生活在樹(shù)冠層。
C
第一個(gè)真正意義上進(jìn)入樹(shù)冠層進(jìn)行研究的英國(guó)人是Sir Francis Drake，他在1573年在巴拿馬的Darien的一刻高樹(shù)第一次看到了太平洋。但是第一個(gè)真正意義上的關(guān)于樹(shù)冠的研究指導(dǎo)1929年才開(kāi)始。Major RWG Hingston領(lǐng)導(dǎo)的牛津大學(xué)科考隊(duì)赴英屬圭亞那進(jìn)行考察，最終在需要建造一個(gè)觀察平臺(tái)時(shí)，他們還是向當(dāng)?shù)厝诉M(jìn)行了求助。這次科考總的來(lái)說(shuō)還是很成功的，盡管代理領(lǐng)導(dǎo)者在坐著轎子參觀的過(guò)程中被卡到懸在空中。就到達(dá)樹(shù)冠這個(gè)層面而吉，法國(guó)人可以說(shuō)是優(yōu)秀的創(chuàng)新者，他們通過(guò)比空氣還輕的平臺(tái)也就是氣球和相關(guān)的設(shè)備來(lái)運(yùn)送東西。來(lái)自Montpellier大學(xué)熱帶植物研究所的Francis Halle在1980年代中期通過(guò)一個(gè)氣球從空中到達(dá)樹(shù)冠。他在法屬圭亞那的工作收了Marcel和Annette Hladic在加蓬共和國(guó)氦氣球的啟發(fā)。Halle更近一部，他乘坐了專(zhuān)門(mén)建造的一個(gè)小型的飛行器——長(zhǎng)得像雪茄形狀的氣球，是靠螺旋槳來(lái)增加機(jī)動(dòng)性的。Mitchell說(shuō)道：“我們突然有了一個(gè)可移動(dòng)的系統(tǒng)來(lái)在樹(shù)梢附近活動(dòng)，除此別無(wú)他法。”
D
自此以后，兩個(gè)以來(lái)氣球的工具就產(chǎn)生了：筏子或是雪橇，筏子是“漂浮著的平臺(tái)”，被法國(guó)學(xué)者Danny Cleyet—Marrel和Laurent Pyot應(yīng)用在樹(shù)頂?shù)囊粋€(gè)小島上，是用橡膠漁網(wǎng)邊緣配上充氣的氯丁橡膠管子做成的。這個(gè)小筏子停留在樹(shù)冠層的頂部，這樣可以讓生物抽樣（主要是植物和昆蟲(chóng)）可以在平臺(tái)的邊緣停留數(shù)日。在另一方面，雪橇呈充氣六邊形，和傳統(tǒng)的氣球籃子相似，在底部的中間有一個(gè)洞，上面覆蓋著橡膠網(wǎng)，當(dāng)然這種技術(shù)不是完美的。萊比錫大學(xué)系統(tǒng)植物研究所主任Dr Wilfried Morawets說(shuō)道：“氣球可以覆蓋更大的區(qū)域，尤其是手機(jī)信息的時(shí)候，但是它們的造價(jià)非常高，Jibe筏子造價(jià)122,000歐元（約合86000英鎊，按2001年的匯率）雖然這種方式很有效，但是只能是研究人員到達(dá)頂部并且對(duì)天氣的依賴性很強(qiáng)。氣球只能在淸早使用2-4小時(shí)，上周整整一周因?yàn)樘鞖庠蛭覀冎荒艹鋈タ疾?次?！辫b于以上因素，就不難理解為什么在1986年和2001年間只存六次研究活動(dòng)采用氣球。
E
接下來(lái)另一個(gè)重要的創(chuàng)新來(lái)自巴拿馬Smithsonian Tropical Research Institute的Alan Smith，他是采用一個(gè)靜止的起重機(jī)來(lái)到達(dá)樹(shù)冠。沒(méi)有繩子拴著的氣球能夠大范圍地采集樣本，但是起重機(jī)可以讓科學(xué)家年復(fù)一年地通年集中研究一公頃的范圍內(nèi)從土壤到樹(shù)冠。Basel大學(xué)的教授Christian Korner認(rèn)為“起重機(jī)比其他任何一種方法都要好，它們好，它們又便宜有可靠而且快速。我可以在兩分鐘之內(nèi)到達(dá)想要到達(dá)的森林的任何位置，這對(duì)于物種間的比較研究至關(guān)重要?！? Christian Korner在瑞士用充滿二氧化碳的空氣中用起重機(jī)進(jìn)行一個(gè)實(shí)驗(yàn)。試圖揭開(kāi)森林將如何應(yīng)對(duì)全球二氧化碳含量上升。為了簡(jiǎn)便起見(jiàn)，起重機(jī)一般都安置在靠近城市或是研究中心，萊比錫大學(xué)在離城鎮(zhèn)不遠(yuǎn)的地方就有一個(gè)研究用的起重機(jī)，該地點(diǎn)可以讓研究者對(duì)污染物對(duì)森林的影響進(jìn)行研究。為了增加起重機(jī)能到達(dá)的樹(shù)冠的數(shù)量，一些起重機(jī)放在短的鐵軌上。在1995年，Dr Wilfried Morawets是第一個(gè)采用這樣技術(shù)的人，在Venezuelan雨林假期了150米的軌道。他說(shuō)道：“在我看來(lái)，起重機(jī)將是未來(lái)研究樹(shù)冠的核心工具。”
F
似乎進(jìn)行樹(shù)冠研究的其他人和Mitchell的觀點(diǎn)一樣，被組委“樹(shù)冠學(xué)家”的Madie Selby Botanical Gardens的執(zhí)行主任Meg Lowan說(shuō)道：“期初許多科學(xué)家肯定認(rèn)為Mitchell瘋了才會(huì)想到建這樣一個(gè)復(fù)雜的實(shí)地觀察站。但是我們逐漸都點(diǎn)識(shí)到，將不同方法進(jìn)行組合，從而能夠用長(zhǎng)期合作的方法來(lái)進(jìn)行生態(tài)研究是推進(jìn)樹(shù)冠研究最好的方法。一個(gè)永久的樹(shù)冠研究站能夠做到這一點(diǎn)?！币蝗褐铝τ谘芯繕?shù)冠的科學(xué)家通力合作，運(yùn)用一系列的工具到達(dá)樹(shù)頂，從而可以真正了解最不為人知的陸地柄息地—樹(shù)冠?！?/p>
