1、年 級高二學 科英語版 本人教新課標版課程標題選修8 Unit5 Meeting your ancestors -words、phrases and language points編稿老師馮振宇一校林卉二校李秀卿審核劉曉軍一、學習目標：知識目標：學習本單元的詞匯、短語和句型。能力目標：能夠使用這些詞匯、短語及句型進行語言表達，并能夠解答與之相關的習題。二、重點、難點：1. 重點：重要單詞alternative, accuracy, interrupt, assume, significance, accelerate, arrest 重要短語regardless of, at most, cu

2、t up, fed up with, look ahead, date back重要句型1) We have been excavating layers of ash almost six metres thick, which suggests that they might have kept the fire burning all winter. 2) It must have been very uncomfortable.3) If only she had looked ahead and planned better this year.2. 難點：“情態動詞+完成式”的意義

3、三、知能提升（一）重點單詞單詞學習1. alternative n.選擇對象；（兩者或兩者以上的）選擇【用法】have no alternative but to do sth.：只能做某事；除外別無選擇【例句】We have no alternative but to go on.除了繼續走下去，我們沒有選擇的余地。 There was no other alternative but to fight till the victory.除了爭取戰斗到勝利，別無選擇。【拓展】alternative n.C 可能的選擇，可能性之一。近義詞：choice。adj.選擇性的，二中擇一的v. 交替；

4、輪流alternatively adv.交替地，作為另一種選擇地alternate vt. 使交替；vi.交替；adj. 交替的；輪流的【考題鏈接】In this school, the students have three _courses, and seven _courses.A. required; alternative B. requiring; alternative C. required; alternate D. requiring; alternate答案：A解題思路：考查詞義和詞性。Require（尤指根據法規）規定、需要，此處用過去分詞required修飾cours

5、es是因為兩者之間為被動關系。后一空的意思為選擇，選其一，作定語，alternative符合句意。2. accuracy n.U精確性，正確度【例句】I doubt the accuracy of your statement. 我懷疑你的話的正確性。He aims at great accuracy.他力求十分準確。 【拓展】accurate adj. 正確的，精確的inaccurate adj.不準確的accurately adv.正確地，精確地inaccurately adv.不準確地【考題鏈接】As his best friend , I can make _ guesses abou

6、t what he will do or think.A. vague B. accurate C. particular D. vain答案：B解題思路：詞義辨析題。根據句意：由于我是他最好的朋友，（故）我能對他的所做所想做出精確的判斷。所以B項符合句意。而vague是“模糊的”意思，particular意為“特別的”，而vain則是“徒勞的”意思。3. interrupt v. 中斷，打擾，打斷，插嘴【例句】Rain interrupted our baseball game.下雨中斷了我們的棒球比賽。The baby interrupted me while I was on the p

7、hone.我在打電話時，嬰兒干擾了我。 It is rude to interrupt.打斷別人的話，是不禮貌的。“Don't interrupt,” he said. 他說：“別插嘴”。【考題鏈接】Traffic in the city was _ by a snowstorm. A. blocking B. hold up C. interrupted D. hold back答案：C解題思路：考查動詞詞義辨析及語態。雖然block, hold up都可以表示“使停頓”，但是A、B兩項的語態錯誤。traffic和謂語動作的關系為被動，只有C項符合。4. assume vt. 假設，

8、臆斷，猜想【例句】We can't assume anything in this case. 在這種情況下我們不可能做出假設。【用法】assumption n. 假定，設想，假裝，就職on the assumption that 假設assumed adj. 假定的，假裝的，裝的【拓展】assume, suppose, presumeassume“假定，設想”，用于邏輯推理，強調一種缺乏證據的結論，以檢驗某種建議。suppose意為“根據一定的證據作出的見解”，最不正式。presume意為“某人以過去的經驗作為依據，對某事作出合乎邏輯的推測”。【考題鏈接】We must _ him

9、to be innocent until he is proved guilty.A. assume B. suppose C. presumed D. pretend答案：A解題思路：考查動詞詞義辨析。根據上面所講幾個詞的區別，這里用assume符合句意。句意為：直到他被證明有罪之前，我們必須假定他是無辜的。5. significance n.意義，意思；重大意義，重要性【例句】This fact has little significance for us. 這一事實對我們沒有什么意義。They failed to appreciate significance of the precau

10、tions.他們沒有意識到這些預防措施的重要性。【拓展】significant adj.重要的，重大的，可觀的be of significance= be significant【考題鏈接】The discovery of these tombs is _for scholars studying the history of the Tang Dynasty.A. of very important B. great significantC. of great significance D. greatly importance 答案：C解題思路：這里important與significa

11、nt為同義詞，且都是形容詞，所以A項應該將of去掉，而B項應該將great改為very。D項需要加介詞of，且將greatly改為great，才符合這一句型結構的要求。6. accelerate vt.&vi. 加速，促進【例句】We must take measures to accelerate the rate of economic growth. 我們必須采取措施，加速經濟增長。The car accelerated as it overtook me. 那輛汽車一加速就超越了我。【用法】acceleration n. 加速度【考題鏈接】The leader is losin

12、g ground as the rest of the runners _. A. accelerate B. promote C. help D. advance 答案：A解題思路：詞義辨析題。A項意為加速，B項意為提升，促進，C項意為幫助，D項的意思是促進。根據句意：領先者正失去優勢，因為其他選手正在加速，可知選A項。7. arrest vt. 逮捕，拘留，吸引(注意) n.C逮捕【例句】The criminal was arrested yesterday. 罪犯昨天被捕了。What she did arrested my attention. 她的行為吸引了我的注意力。【用法】be a

13、rrested for sth. 因某事而被捕arrest one s attention吸引某人的注意under arrest被捕；被拘留【考題鏈接】He was _ for stealing a car.A. accused B. arrested C. sentenced D. charged答案：B解題思路：詞義辨析題。A項后面的介詞應該為of，D項后面的介詞則為with，C項sentence的意思為宣判，在這里不合句意。所以B項“被捕”正確。即學即練1. There are several_ plans and its up to you to decide which to cho

14、ose.A. alternative B. according C. effective D. positive2. The description was pretty , so the police couldn't figure out the portrait of the criminal.A. vague B. accurate C. correct D. true3.

Gao Xiaosong was arrested_ drunken driving on his way home in Beijing.A. with B. of C. for D. to（二）重點短語短語學習1. re

16、gardless of 不管；不顧【例句】I ll take the job regardless of the pay. 不管報酬多少我都要做這份工作。He says what he thinks, regardless of other people s feelings. 他怎么想就怎么說，不考慮別人的情緒。【拓展】同義詞、短語：disregarding /in spite of /despite，它們的意義和用法相同，區別不大。【考題鏈接】This special school accepts all disabled students, _ educational level and

17、 background.A. according to B. regardless of C. in addition to D. in terms of答案：B 解題思路：考查介詞短語的用法。according to 根據；regardless of 不管，不顧；in addition to 另外；in terms of 就而言。根據句意：這所特殊學校接收所有的殘疾學生，不管他們的教育水平和背景如何，可知B項正確。2. at most 最多【例句】The trip will only cost you fifty pounds at most. 這次旅行最多只會花去你50英鎊。【拓展】at

18、least 至少at the latest 最遲at last 最后3. cut up切碎；使傷心，嚴厲批評【例句】Peter, why dont you cut up vegetables? 彼得，為何不把蔬菜切碎呢？【拓展】由cut 組成的常用短語：cut off切斷；剪掉cut down砍伐；削減cut in打斷cut out剪去，刪去，略去cut into pieces砍成碎片【例句】Don't cut in while I'm talking. 我說話時別插嘴。【考題鏈接】When the mother returned, she saw her son _veget

19、ables into pieces.A. cut down B. cut up C. to cut down D.to cut up答案：B解題思路：考查cut 的相關短語和非謂語動詞的用法。cut down砍伐；削減，cut up切碎，由句意可知用cut up。再由see sb. do sth.句式可知選B。4. fed up with受夠了，厭煩【例句】Im fed up with waiting for her to telephone. 我等她的電話都等得不耐煩了。Whats the matter? You look pretty fed up. 怎么啦？你顯得那么不高興。【拓展】fe

20、ed的相關短語：feed sb./sth. on sth.給（人或動物）食物；喂；飼養 feed sth. to sb/sth. 將某種食物喂給人或動物feed on（動物）以為主食【考題鏈接】根據句子的要求在橫線上填入適當的介詞。1) Several children were feeding bread _ the ducks. 2) What do you feed your dog _? 3) Cows feed _ grass. 4) I m fed up _ the same breakfast every morning.答案：1) to 2) on 3) on 4) with5

21、. look ahead向前看；為將來謀劃（打算）【例句】Have you looked ahead to what you ll be doing in five years time? 你是否想過五年后你要做些什么?【拓展】look的相關短語：look back 向后看；回顧look out 留神；注意look into 調查look up 查找；形勢好轉；看望look up to sb. 尊敬某人look through 仔細查閱look forward to sth./doing sth. 盼望look on 旁觀；看作look over 快速瀏覽，復習look down (on/up

22、on sth.) 向下看；輕視【考題鏈接】My students look _me very much.A. down upon B. up to C. back to D. into答案：B解題思路：考查固定短語。由句意：我的學生非常尊敬我。可知look up to sb.“尊敬某人”符合句意。6. date back = date from. 追溯到，從時候開始就有了【例句】The temple dates back to the 13th century. 這座寺廟從十三世紀開始就有了。【考題鏈接】The custom _ the Ming Dynasty has died out.A.

23、 dates from B. dates back to C. that dated from D. dating from答案：D解題思路：解答本題首先要確定形式，根據后面的謂語動詞has died down可排除掉A、B兩項，若選擇這兩項的話就會出現兩個謂語動詞，而C項的時態錯誤，所以D項為正確選項。即學即練1. Traditionally, Chinese people _ the Chinese characters Double Happiness and stick them onto walls or doors for weddings. A. cut out B. cut o

24、ff C. cut up D. cut down2. Some people act regardless _what will happen afterwards.A. with B. as C. of D. for3. It is reported that the police will soon _ the case of two missing children. A. look upon B. look after C. look into D. look out4. It'll take _ 2 hours to do this!Oh, come on! I could

25、do it in 30 minutes.A. at least B. at most C. at the latest D. at last（三）重點句型句型學習1. We have been excavating layers of ash almost six metres thick, which suggests that they might have kept the fire burning all winter. 句子分析本句中的suggest表示“表明”。suggest最常用的兩個意思：（1）提議；提出；建議，后接動詞時要用動詞的ing形式，后接賓語從句時，從句用虛擬語氣（“

26、should+動詞原形”，should常省略）。【例句】It s noisy here. I suggest changing another hotel. 這里太吵了，我建議換個賓館。I suggest (that) you (should) ask Mr. Wu. 我建議你問問吳先生。I suggest that the boy be sent to the hospital at once. 我建議立即把小孩送到醫院。后接賓語從句要用虛擬語氣的詞可記為：一個堅持：insist / 兩個命令：command, order / 四個建議：advise, suggest, recommend,

27、 propose / 四個要求：ask, demand, request, require（2）表明，顯示，暗示；顯出，后接賓語從句（不用虛擬語氣）。【例句】His expression suggests that he has got the job.他臉上的表情表明他已經得到了那份工作。【考題鏈接】Johnson suggested the problem worth paying attention _ at the meeting. A. to be discussed B. to been discussedC. being discussed D. should be discus

28、sed答案：A解題思路：本題考查虛擬語氣和句子結構分析。由句意“建議被討論”可知，后邊應為 (should) be discussed 結構，可排除B、C兩項；再由pay attention to 短語可知選A項。此處worth paying attention作后置定語修飾the problem。2. It must have been very uncomfortable.句子分析這里的must have been表示對過去情況的肯定猜測：情態動詞+完成式的用法情態動詞+完成式往往表示過去的事情，情態動詞不同意義也不同，現簡要總結如下：can, could后接完成式，在否定句或疑問句中表示

29、對過去發生過的事情的“懷疑”或“不肯定”的態度。【例句】Where could I have put my cell phone? I cant find it anywhere.我會把手機放在哪里呢？我到處都找不到。could用在肯定句中，可以表示過去可能做到而實際并沒做到的事情，有“勸告”或“責備”的語氣。【例句】Its too late. You could have answered it earlier, I am sure. 太晚了。你可以回答得更早一些，我肯定。may, might后接完成式表示對過去某事的推測，認為某件事情在過去可能發生了。如果用might，語氣則更婉轉或更不肯

30、定。【例句】Mary might have learned some Chinese before. 瑪麗以前可能學過一些漢語。還可以表示過去本來可以做到而實際沒有做到的事情，有“勸告”或“責備”的語氣。【例句】You didnt do the work well that day. You might have done it better. 你那天做得不夠好。你本可以做得更好的。must后接完成式的用法：表示對過去某事的推測，認為某事在過去一定做到了。【例句】Your performance is so good. You must have trained very hard. 你的表演

31、這么好。你一定訓練得很刻苦吧。 should/ought to后接完成式表示過去沒有做本來應該做的事情，或是做了本來不應該做的事情。【例句】You shouldnt have spent so much time playing computer games this weekend. 這個周末你不該花費那么多時間玩電腦游戲的。neednt have done用來表示本不必要做卻做了的事情。【例句】Today is Sunday, so you neednt have got up so early.今天是星期天，你本不必起這么早的。【考題鏈接】Why? Where is your purse

32、?Dear me! I it in the taxi. A. should have left B. must have left C. need have left D. would have left答案：B解題思路：從所給的四個選項來看，都是“情態動詞+完成式”，故要看句意與這幾種結構的意義，首先排除掉C項，因為need用作情態動詞時往往用于否定句，而should have done表示本應該做卻沒有做的事情；D項則是本應干什么，但沒干，根據句意：天哪，我一定是忘在出租車上了可知選B。3. If only she had looked ahead and planned better t

33、his year.句子分析這里的if only意為但愿；要是就好了。其后一般用虛擬語氣：If only I were a doctor. 這句話用的是一般過去時，因為原意是：我現在要是個醫生就好了。與現在時態相對應的句子用一般過去時。If only I had said nothing. 而這句用的是過去完成時，原意為：我當時不說就好了。是與過去時態相對應的，故用過去完成時。If only my son didn't spend so much time before TV. 這句可以理解為一般現在時的虛擬語氣，所以句子中使用了一般過去時。原意為：要是我兒子不在電視前面呆那么長時間就好

34、了。【拓展】only if表示“只有，只要”，后接讓步狀語從句，主句采用倒裝句式：Only if a teacher has given permission is a student allowed to enter this room.只有老師同意，學生才能被允許進入這個房間。【考題鏈接】Look at the trouble Im in! If only I _your advice.A. followed B. would follow C. had followed D. should follow答案：C解題思路：考查if only引導的從句。if only引導的條件狀語從句用虛擬

35、語氣。即學即練1. Why were you driving so fast? You _somebody. A. might hurt B. might have hurt C. would hurt D. must have hurt2.

Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individualthe sort of environment
