tropical forest any longer because his health was in poor________． 答案：condition 句意：柯林斯博士不能領(lǐng)導(dǎo)在熱帶雨林里的野生動物研究了，因為他的身體狀況很壞(in poor condition)。,(2)I agree to his suggestion________the condition that he drops all charges． 答案：on 句意：我同意他的建議，條件是他放棄所有指控。on the condition that起連詞作用，引導(dǎo)條件狀語從句，意思是“條件是，以……為條件”。,1．The popularity of films such as Jurassic Park，in which a scientist clones several

popularity.proves.，句中how引導(dǎo)賓語從句；主句中又包含in which引導(dǎo)的非限制性定語從句，先行詞為Jurassic Park。 The school (which/that) he once studied in is very famous．＝The school in which he once studied is very famous． 他曾經(jīng)就讀過的學(xué)校很有名。 There are sixty students in our class in all，most of whom are from big cities． 我們班總共有60個學(xué)生，大多數(shù)來自大城市。,注意：“介詞＋關(guān)系代詞”引導(dǎo)的定語從句一般根據(jù)三個原則來確定介詞：①根據(jù)從句的謂語動詞；②根據(jù)先行詞；③根據(jù)句子意思。但也有許多考題需要我們把從句補(bǔ)充完整，建立與主句的聯(lián)系，才能找到這個介詞與句中其他部分的關(guān)系。,活學(xué)活用 用恰當(dāng)詞填空 She showed the visitors around the museum，the construction ________ ________had taken more than three years． 答案：of which 考查定語從句。句意：她帶領(lǐng)游客參觀這家博物館。這家博物館的建設(shè)歷經(jīng)三年多才完工。定語從句中whose＋名詞＝of which＋the＋名詞＝the＋名詞＋of which，由此可知答案為of which。,2．Diversity in a group means having animals with their genes arranged in different ways． 種群多樣性是指種群中動物的基因要以不同的方式排列。 (1)本句是簡單句，動名詞短語having animals.作means的賓語，with復(fù)合結(jié)構(gòu)(即“with＋賓語＋賓補(bǔ)”結(jié)構(gòu))作后置定語，arrange與their genes為動賓關(guān)系。,(3)with復(fù)合結(jié)構(gòu)的用法： 作定語 She saw a brook with red flowers and green grass on both sides． 她看到一條兩岸長著紅花和綠草的小溪。 作狀語 ①She left the office with tears in her eyes．

with結(jié)構(gòu)并不難，with后面賓語連， 動賓關(guān)系用過分，主謂關(guān)系用現(xiàn)分， 將來要把不定跟，還有三種形副介。,活學(xué)活用 用所給動詞的適當(dāng)形式填空 (1)With so many essays________(write)，he wont have time to go shopping this morning． 答案：to write (2)He felt more uneasy with the whole class________(stare)at him． 答案：staring,(3)With a growing number of college graduates________ (consider)themselves to belong to the lower levels of

extinct animals if they were to live in a zoo． 任何絕種的動物，如果一經(jīng)克隆便注定要生活在動物園里的話，那是不公平的。 本句是虛擬條件句，且表示的是與將來事實相反的假設(shè)。虛擬條件句在不同虛擬條件下，主從句謂語形式一覽表：,If it should rain tomorrow，the meeting would be put off． 如果明天下雨，會議將延期。 If I had lots of money，I would buy a car． 如果我有很多錢，我就買一輛小汽車。 If he had won the game，he would not have been so sad．

go for a picnic with you． 如果明天不考試的話，我就和你一起去晚餐。,活學(xué)活用 用恰當(dāng)詞語填空 (1)(2015真題改編北京)If I________(see)it with my own eyes ，I wouldnt have believed it． 答案：hadnt seen 句意：如果不是我親眼看到，我不會相信。根據(jù)后半句wouldnt have believed可以判斷是對過去的虛擬。所以從句是if＋主語＋ had done的形式。故填hadnt seen。,(2)(真題改編北京)We ________ (be)back in the hotel now if you didnt lose the map． 答案：would be 考查虛擬語氣。根據(jù)從句的時態(tài)可知，空格處表示對現(xiàn)在情況的假設(shè)，再結(jié)合if虛擬句的特點(diǎn)可知應(yīng)填would be。句意：要是你沒有把地圖弄丟了的話，我們現(xiàn)在就已經(jīng)回到旅館了。,(3)(真題改編福建)________ (be)there no modern telecommunications，we would have to wait for weeks to get news from around the world． 答案：Were 考查虛擬語氣的倒裝。根據(jù)主句中的would have to wait可知，空格處應(yīng)表示對現(xiàn)在情況的假設(shè)，故從句用一般過去式；另外，當(dāng)if從句中含有be動詞were及助動詞had時，可以把主語和if省略，同時把were或had提前，構(gòu)成倒裝句。句意：如果沒有現(xiàn)代化的電信設(shè)施的話，我們將不得不等候好幾周的時間來獲得來自世界各地的消息。,4．Based on what we know now，you cannot clone animals that have been extinct longer than 10,000 years． 就我們現(xiàn)在所知，你不可能克隆那些已經(jīng)絕種超過一萬年的動物。 過去分詞短語based on.作狀語。介詞on后接what引導(dǎo)的賓語從句。句中that引導(dǎo)定語從句，先行詞為animals。過去分詞作狀語的用法主要有：,①作原因狀語，相當(dāng)于as，since，because引導(dǎo)的從句，這類狀語多放在句子的前半部分。 Given advice by the famous detective，the young lady was no longer afraid．(Since/As she was given advice by the famous detective.) 有了著名的偵探的指點(diǎn)，這位年輕的女士不再害怕了。 ②作時間狀語(相當(dāng)于when引導(dǎo)的狀語從句。如果兩個動作同時發(fā)生，可在分詞前用when，while等使其時間意義更明確。),When heated，water can be changed into steam． 水加熱后可以變成蒸汽。 Discussed (Having been discussed) many times，the problems were settled at last． 在討論了多次之后，問題終于解決了。(過去分詞既表被動又表完成) Seen from the hill，the park looks very beautiful． 從山上看這個公園非常漂亮。(過去分詞只表被動),③作條件和假設(shè)狀語(相當(dāng)于if，unless引導(dǎo)的從句) Given more time，we can finish the task on time． 如果被給更多的時間，我們能按時完成這項任務(wù)。 ④作方式或伴隨情況狀語 The hunter left his house，followed by his dog． 獵人離開了屋子，后面跟著他的狗。 She sat by the window，lost in thought． 她坐在窗前，陷入沉思。,注意：分詞短語作狀語時，其邏輯主語要與句子的主語保持一致，否則分詞短語就要有自己的邏輯主語(用名詞或代詞的主格來表示)，這種結(jié)構(gòu)稱為獨(dú)立主格結(jié)構(gòu)。 All our savings gone，we started looking for jobs． 積蓄全部用完了，我們就開始找工作。(All our savings gone是含有過去分詞的獨(dú)立主格結(jié)構(gòu)) He rushed into the room，his face covered with sweat． 他滿臉是汗地沖進(jìn)屋內(nèi)。(his face covered with sweat是包含過去分詞的獨(dú)立主格結(jié)構(gòu)),活學(xué)活用 用恰當(dāng)形式填空 (1)(真題改編天津)Clearly and thoughtfully ________ (write)，the book inspires confidence in students who wish to seek their own answers． 答案：written 考查非謂語動詞。句意：因為清晰周到地被寫出來，這本書鼓舞了想尋找自己答案的學(xué)生的自信心。the book與write之間是邏輯上的動賓關(guān)系，故填written。,(2) (2015真題改編重慶)Like ancient sailors，birds can find their way________(use)the sun and the stars． 答案：using 句意：象古代的水手，鳥能利用太陽和星辰來找到他們的路。using是伴隨狀語。伴隨狀語是指狀語從句的動作伴隨主句發(fā)生，它的特點(diǎn)是：它所表達(dá)的動作或狀態(tài)是伴隨著句子謂語動詞的動作而發(fā)生或存在的。,5．So the chances of dinosaurs ever returning to the earth is merely a dream！ 所以說恐龍回歸地球的可能性僅僅是個夢想罷了！ dinosaurs ever returning to the earth 為“動名詞的復(fù)合結(jié)構(gòu)”，在句中作介詞of的賓語。動名詞帶上自己的邏輯主語，就構(gòu)成了動名詞的復(fù)合結(jié)構(gòu)。其邏輯主語一般由物主代詞、名詞所有格、人稱代詞的賓格和名詞來充當(dāng)。在口語中，物主代詞和名詞所有格可分別由人稱代詞的賓格或名詞代替。在句中可以充當(dāng)主語、賓語或表語。,①Would you mind my/me opening the window？ 我打開窗子你介意嗎？ ②He insisted on his sons/his son going to college． 他堅持讓他兒子上大學(xué)。,知識拓展 (1)動名詞復(fù)合結(jié)構(gòu)作主語或動名詞本身為being時，用“物主代詞/名詞所有格＋v．ing” Marys coming late made her teacher Mr．Smith quite angry． 瑪麗的遲到使她的老師史密斯先生非常生氣。 (2)動名詞的邏輯主語為無生命的東西時，用“普通格＋v．ing” Is there any hope of our team winning the game？ 我們的球隊有獲勝的希望嗎？,(3)有生命的名詞但表示泛指意義，用“普通格＋v．ing” Have you ever heard of women playing football？ 你聽說過婦女踢足球的事嗎？ (4)兩個以上的有生命的名詞并列時，用“普通格＋v．ing” Do you remember my brother and me coming to see you the other day？ 你記得我弟弟和我前幾天來看你那件事嗎？,(5)動名詞的邏輯主語為復(fù)數(shù)名詞時，用“普通格＋v．ing” There are many reasons for animals dying out． 動物滅絕有多種原因。 (6)動名詞的邏輯主語被其他成分說明或修飾時，用“普通格＋v．ing” Have you heard of Miss Gao，our English teacher，going to the USA？ 你聽說我們的英語教師高老師要去美國嗎？,活學(xué)活用 用恰當(dāng)形式填空 (1)His________(come)late for class again made his teacher very angry． 答案：coming 句意：他上課又遲到讓老師非常生氣。分析句子結(jié)構(gòu)可知made前的成分為主語，而橫線前的his暗示此處應(yīng)為動名詞的復(fù)合結(jié)構(gòu)作主語。,(2)________(the president；attend)the meeting himself gave them a great deal of encouragement． 答案：The presidents attending 句意：總統(tǒng)親自參加會議給了他們莫大的鼓舞。本題考查動名詞的復(fù)合結(jié)構(gòu)作主語，必須采用“名詞的所有格＋v．ing的形式”。,寫作指導(dǎo) 如何寫辯論報告 Ⅰ．寫作策略探究 這類文章要求用一定的理由來說明自己對事物或問題的見解，屬于議論文的范疇。寫作時要注意以下幾點(diǎn)：,1．篇章特點(diǎn) 議論文是一種以議論為主要表達(dá)方式的文體。就是擺事實、講道理，并要求通過多方面的分析，把道理說通、說透。議論文有三要素，即論點(diǎn)、論據(jù)和論證。論點(diǎn)的基本要求是：觀點(diǎn)正確，認(rèn)真概括，有實際意義，恰當(dāng)?shù)鼐C合運(yùn)用各種表達(dá)方式；論據(jù)的基本要求是：真實可靠，充分典型；論證的基本要求是：推理必須符合邏輯。,2．注意事項 寫作時應(yīng)注意： 第一，要提出正確鮮明的論點(diǎn)。一般來說，要把論點(diǎn)寫在篇首或段首，這樣能起到綱舉目張的效果，讓讀者讀起來更容易把握文章思路。 第二，要重視論據(jù)這一關(guān)的闡述。論據(jù)就是用來證明論點(diǎn)的事實和道理。要有足夠的論據(jù)，可以列舉生活的實例來證明論點(diǎn)。 第三，論證是議論文中必不可少的部分。一段完整的議論，只有通過論證證明論據(jù)和論點(diǎn)之間的內(nèi)在邏輯關(guān)系，才能將論據(jù)和論點(diǎn)融為一體，也才能構(gòu)成一篇完整的、有說服力的文章。,3．寫作形式 此類作文一般有兩種寫法。 (1)文章分三部分進(jìn)行論述： 第一部分：提出論點(diǎn) 第二部分：給出論據(jù) 第三部分：得出結(jié)論 (2)文章分四部分進(jìn)行論述 第一部分：說明辯論的主題、參與者等 第二部分：列舉正方的觀點(diǎn)及其理由 第三部分：列舉反方的觀點(diǎn)及其理由 第四部分：闡明自己的觀點(diǎn),4．常見的寫作用語 總結(jié)： There are different opinions among people as to. We had a heated discussion about. Different people hold different opinions． Opinions are divided． People have taken/adopted different attitudes towards. People have different opinions on this problem． People take different views on this question．,表達(dá)不同觀點(diǎn)： .of them hold the opinion that. .of them are in favour of the idea that. People who are for/against the idea think.
