讓雅思索官來教你雅思閱讀多選題的正確解題步驟

接下來，讓雅思索官來教你正確的解題步驟：

1.Readthequestionandunderlinethekeywords-thesearethewordsthatyouwilltrytofindinthepassage(themainwordsthatgivethemeaningofthequestion).

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

2.Readthechoicesandunderlineoneortwokeywordsforeachone.Focusonwordsthatmakethedifferencebetweeneachchoice.

讀選項，每個劃出一兩個關(guān)鍵詞。認(rèn)真討論每個選項的差別

3.Gotothepassageandlookforthekeywordsfromthequestion.

去文章找到問題中的關(guān)鍵詞

4.Whenyouhavefoundtherightpartofthepassage,lookforkeywordsfromthechoices.

當(dāng)你找到答案段落，查找選項中的關(guān)鍵詞

5.Readtherelevantpartofthepassagecarefully,comparingittoeachchoice.

認(rèn)真閱讀相關(guān)段落，和每個選項做比較

6.Tobesureyouhavetherightanswer,youshouldbeabletoshowthattheotheranswerchoicesarewrong.

你確定你有正確答案的時候應(yīng)當(dāng)能證明其它的是錯的

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——如何推斷題點在原文中的位置。比如劍4-94頁的20-21題：Thelistbelowgivessomestatementsaboutanthropology。WhichTWOstatementsarementionedbythewriterofthetext?一看題目讓我們找anthropology相關(guān)的東西，翻回原文發(fā)覺文章標(biāo)題是archeology，所以整篇文章確定都在說archeology，而我們要找的anthropology確定只是其中集中敘述的一個插曲段落。所以出題位置確定相對集中，而且確定明顯包含anthropology字樣。只需略微瞟一眼整篇文章，很快就能發(fā)覺，幾乎每一段的開頭都是以archeology開頭，唯一例外的是第4和5段，以anthropology開頭。所以20-21確定就在這兩段之內(nèi)。這是依據(jù)題干的關(guān)鍵詞來推想定位。

樹冠的討論者

A

森林樹冠層是用來描述森林中全部樹冠總和的術(shù)語，是超過40%生物物種的棲息地，其中10%的物種是只生活在樹冠上的。GlobalCanopyProgramme是特地討論樹冠的組織，它的執(zhí)行主席AndrewMitchell說道：“我們正在討論地球上最豐富，最鮮為人知但是又最受威逼的棲息地。我們對森林熟悉的問題在于幾乎全部我們收集的信息只是從距離地面2米的地方獲得的，但是我們卻要以此討論關(guān)于距離地面60米髙的樹，或是最高達(dá)112米的紅木這樣的樹木的問題。這就好比醫(yī)生只能通過看病人的腳來治愈病人?！?/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)系的簡單性上來講，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冠上，據(jù)估量雨林中70%-90%的生物居住在樹上，有非常之一的導(dǎo)管植物是生長在樹冠層，大約20%-25%的無脊椎動物只生活在樹冠層。

C

第一個真正意義上進(jìn)入樹冠層進(jìn)行討論的英國人是SirFrancisDrake，他在1573年在巴拿馬的Darien的一刻高樹第一次看到了太平洋。但是第一個真正意義上的關(guān)于樹冠的討論指導(dǎo)1929年才開頭。MajorRWGHingston領(lǐng)導(dǎo)的牛津高?？瓶缄牳坝俟鐏喣沁M(jìn)行考察，最終在需要建筑一個觀看平臺時，他們還是向當(dāng)?shù)厝诉M(jìn)行了求助。這次科考總的來說還是很勝利的，盡管代理領(lǐng)導(dǎo)者在坐著轎子參觀的過程中被卡到懸在空中。就到達(dá)樹冠這個層面而吉，法國人可以說是優(yōu)秀的創(chuàng)新者，他們通過比空氣還輕的平臺也就是氣球和相關(guān)的設(shè)備來運送東西。來自Montpellier高校熱帶植物討論所的FrancisHalle在1980年月中期通過一個氣球從空中到達(dá)樹冠。他在法屬圭亞那的工作收了Marcel和AnnetteHladic在加蓬共和國氦氣球的啟發(fā)。Halle更近一部，他乘坐了特地建筑的一個小型的飛行器——長得像雪茄外形的氣球，是靠螺旋槳來增加機(jī)動性的。Mitchell說道：“我們突然有了一個可移動的系統(tǒng)來在樹梢四周活動，除此別無他法?！?/p>

D

自此以后，兩個以來氣球的工具就產(chǎn)生了：筏子或是雪橇，筏子是“漂移著的平臺”，被法國學(xué)者DannyCleyet—Marrel和LaurentPyot應(yīng)用在樹頂?shù)囊粋€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。這個小筏子停留在樹冠層的頂部，這樣可以讓生物抽樣（主要是植物和昆蟲）可以在平臺的邊緣停留數(shù)日。在另一方面，雪橇呈充氣六邊形，和傳統(tǒng)的氣球籃子相像，在底部的中間有一個洞，上面掩蓋著橡膠網(wǎng)，當(dāng)然這種技術(shù)不是完善的。萊比錫高校系統(tǒng)植物討論所主任DrWilfriedMorawets說道：“氣球可以掩蓋更大的區(qū)域，尤其是手機(jī)信息的時候，但是它們的造價特別高，Jibe筏子造價122,000歐元（約合86000英鎊，按2022年的匯率）雖然這種方式很有效，但是只能是討論人員到達(dá)頂部并且對天氣的依靠性很
