草船借箭

學(xué)校班級(jí)姓名等級(jí)

一、看拼音寫詞語(yǔ)。

dù jìdū dutuī quayán chítàn tīnɡm(xù)àn zǐsī zì（）（）（）（）（）（）（）diào dùshuǐ zhàil?i ɡǔ nà hǎnzhī yuánch?nɡ xiànɡxiàn qī（）（）（）（）（）（）zhí yǒu miào y?nɡsh?n jī miào suàn

（）（）

二、在括號(hào)里填上恰當(dāng)?shù)年P(guān)聯(lián)詞。

1、周瑜（）知道了，我的計(jì)劃（）完了。

2、（）諸葛亮（）能在三天之內(nèi)造十萬支箭。

3、（）諸葛亮識(shí)天文，懂地理，（）他答應(yīng)周瑜三天內(nèi)造十萬支箭。

三、按課文內(nèi)容填空。

1、課文是按照事情發(fā)展順序?qū)懙模葘懥耍又鴮懥耍貙懥耍詈髮懥恕?/p>

四、多項(xiàng)選擇：

從文中哪里可以看出諸葛亮“神機(jī)妙算”？正確的打“√”。

①他知道第三天四更時(shí)分一定有大霧。（）

②他算好了受箭的方法，二十條船可以繩索相連，一字排開，兩面受箭。（）

③他算好了人，知道魯肅忠厚誠(chéng)信向他借船沒事，周瑜聰明過人，曹操生性多疑。（）④諸葛亮能算，因?yàn)樗巧裣伞＃ǎ?/p>

五、品味探究。

1、“魯肅回來報(bào)告周瑜，果然不提借箭的事，只說??”

從這句話中，我感受到魯肅。

2、從“諸葛亮又下令把船掉過來，船頭朝東、船尾朝西，仍舊擂鼓吶喊”從這句話中，我感受到諸葛亮。

3、“霧這樣大，曹操定不敢派兵出來。我們只管飲酒取樂，天亮了就回去。”

這段話是對(duì)說的，表現(xiàn)了他的特點(diǎn)。

4、從“曹操下令說：‘江上霧大??不要輕易出動(dòng)。只叫弓弩手朝他們射箭??’”從這句話中，我感受到諸葛亮，曹操。

1.Taking frequent short breaks is better for you than one long holiday, psychologists have found.1 believe that people who use their holiday allowance in bursts 2 all in one go are happier.They claimed that people who 3 so-called mini-breaks have more 4 memories than those who spend their holidays for an extended period of time.Dan Ariely, a famous behavioural economist who 5 The Upside of Irrationality, suggested that holidaymakers 6 extended time away by doing some work in the middle of their break 7 this would make them more appreciative of their time away from the 8.The explanation is that people’s enjoyment wanes(減弱)as they become 9 to their holiday lifestyle.Professor Ariely, who 10 at Duke University in North Carolina, said, “On a long 11 , day seven is not as good as day one 12 it is not as exciting.That’s why 13 , going away four times a year provides more 14 than you would expect, and going away for one 15 is not as good as you would expect.”

the polyps die, their bodies decay.Their hard skeletons remain behind.2 Gradually, over long periods of time, reefs of coral skeletons are built up in the ocean, with living coral on the surface.3 It stretches for more than 1300 miles along the Northern Eastern coast of Australia.The Great Barrier Reef has more than 2600 kinds of coral altogether.It is the largest group of coral in the world.All together, it covers an area about half the size of Texas.The Great Barrier Reef does a lot of things for a lot of people, not just fish.It gives the fishermen plenty of fish, gives the tourists something to look at, and gives the scientists something to study.4 This happens by pollution and throwing anchors on the Great Barrier Reef.Worldwide, there are more than 4000 kinds of reef fish.The Great Barrier Reef supports about 1500 different species of fish.Some of the fish that live in it are crabs, sea turtles, sea sponges, and colourful marine worms.5 Those are only some of the species out of the thousand, and still we find more species every year.However, if we don’t start protecting the reef the fish will be in danger or eventually die.A.Coral only grows a few inches each year.B.New polyps grow on the top of the ones that died.C.You realize it is the home of millions of different fish.D.Here are some facts about coral that are really interesting.E.The Great Barrier Reef is one of the earth’s natural wonders.F.However, many people kill parts of it, and it is in danger of extinction.G.Also, you would probably see a big blue starfish, snails with beautiful shells and sharks.Ⅴ.短文改錯(cuò)

1.on purpose 2.a series of 3.fell in love 4.were packing up 5.was tired of Ⅱ.語(yǔ)法和詞匯知識(shí)

1.B 在It’s high time that...句型中, 從句通常用虛擬語(yǔ)氣, 謂語(yǔ)動(dòng)詞用一般過去式。句意:我認(rèn)為的確到我們采取有效措施阻止事故發(fā)生的時(shí)候了。故B項(xiàng)正確。

2.B 這是一個(gè)強(qiáng)調(diào)句, 被強(qiáng)調(diào)的部分是in Beihai Park, 其后跟有where引導(dǎo)的定語(yǔ)從句。句意:這對(duì)老夫婦就是在他們第一次約會(huì)的北海公園里給我們講了他們的愛情故事。for the first time作狀語(yǔ)修飾made a date, 故B項(xiàng)正確。

3.C 句意:——你還相信愛嗎?——非常相信。不是時(shí)間、金錢、權(quán)力而是愛能治愈我們的痛苦。這是一個(gè)強(qiáng)調(diào)句, 被強(qiáng)調(diào)部分用not...but連接。

4.A 句意:面對(duì)恐怖主義的威脅, 他們同意將政治上的分歧放在一邊, 團(tuán)結(jié)起來保衛(wèi)國(guó)家的安全。set aside “把??放在一邊”;set about “開始著手(做??)”;set off “出發(fā), 引爆”;set up “建立”。根據(jù)句意選A項(xiàng)。

5.A 考查非謂語(yǔ)動(dòng)詞及被動(dòng)語(yǔ)態(tài)。concerned...此處為過去分詞短語(yǔ)作后置定語(yǔ), 修飾all those;后一個(gè)空應(yīng)用過去分詞構(gòu)成被動(dòng)語(yǔ)態(tài)。句意:所有那些關(guān)心貧困兒童的人都應(yīng)該受到感謝。6.A 考查強(qiáng)調(diào)句型的特殊疑問句。由or可以判斷, 此句中疑問詞用which, which后用疑問語(yǔ)序, 而which 又是強(qiáng)調(diào)句中被強(qiáng)調(diào)的部分, 因此強(qiáng)調(diào)句中用that, 故選A項(xiàng)。

7.A “in order to + 動(dòng)詞原形”引導(dǎo)目的狀語(yǔ);so that 和in order that引導(dǎo)從句;because of 引導(dǎo)原因狀語(yǔ), 后面接名詞或動(dòng)詞-ing形式。句意為:游客們?yōu)榱嗽谑c(diǎn)以前到達(dá)云臺(tái)山, 很早就出發(fā)了。

8.D not...until的強(qiáng)調(diào)句型為:It is/was + not until...+ that/who...。

9.D 句意:我以前經(jīng)常跟父母吵架, 但現(xiàn)在我們相處得很好。look out “當(dāng)心, 小心”;stay up “熬夜, 挺住”;carry on “繼續(xù), 進(jìn)行”;get along “相處”, get along well “相處得好”。從前面的quarrel a lot和but可知, 這里指 “相處得好”。

10.B 句意:我們大家都知道, 好朋友會(huì)讓生活更幸福、更有意義。as引導(dǎo)非限制性定語(yǔ)從句, 用逗號(hào)和主句分開了。add...to...“把??增加到??, 為??增添??”;add to “增加, 增添”;add up “加起來”。

11.B 句意:我們都被這個(gè)受騙后被賣到山村的小女孩的經(jīng)歷震驚了。go through “經(jīng)受, 經(jīng)歷”;get through “通過, 用完, 完成”;live up to “達(dá)到, 符合, 不辜負(fù)(別人的期望)”;go against “反對(duì), 不利”。根據(jù)句意選B項(xiàng)。

12.D make + 賓語(yǔ) + 賓語(yǔ)補(bǔ)足語(yǔ)(多由名詞、形容詞、動(dòng)詞原形或過去分詞來充當(dāng))意思是 “使??”。題干中make用作了被動(dòng)語(yǔ)態(tài), 形容詞possible作主語(yǔ)補(bǔ)足語(yǔ)。句意:現(xiàn)代科學(xué)技術(shù)的發(fā)展已經(jīng)使得太空探索成為可能。

13.D You are always energetic意為 “你總是充滿活力”。powerful “強(qiáng)大的, 有力的”;weak “虛弱的, 薄弱的”;forceful “強(qiáng)有力的, 堅(jiān)強(qiáng)的, 有說服力的”;energetic “精力充沛的”。故D項(xiàng)正確。

14.D 句意:——大衛(wèi), 我是弗蘭克。你有幾分鐘時(shí)間嗎?我想見你。——我想我有時(shí)間, 但我希望幾分鐘別變成一小時(shí)。I’m afraid not “恐怕不行”;It doesn’t matter “沒關(guān)系”;I don’t think so “我想我沒空”。根據(jù)句意, 選D項(xiàng)。

15.D I guess not意為 “我不那么認(rèn)為”。根據(jù)所提供的情景, 可判斷說話人不同意對(duì)方的觀點(diǎn)。句意:——這個(gè)男孩的詞匯量有限, 是嗎?——我不那么認(rèn)為。他的詞匯量很大。Ⅲ.完形填空

第五篇：XX中學(xué)限時(shí)作業(yè)實(shí)施方案

XX中學(xué)限時(shí)作業(yè)實(shí)施方案

為進(jìn)一步推進(jìn)教學(xué)改革，減輕學(xué)生課業(yè)負(fù)擔(dān)，提高教育教學(xué)質(zhì)量，特制定限時(shí)作業(yè)方案如下。

一、限時(shí)作業(yè)的實(shí)施要求

1.作業(yè)布置內(nèi)容：

常規(guī)作業(yè)僅限于綜合能力訓(xùn)練和學(xué)案上的部分習(xí)題，雙休日作業(yè)限于配套練習(xí)冊(cè)和由教師整理的專門雙休日作業(yè)講義，除此之外不得安排其它教輔材料上的習(xí)題。

2.作業(yè)內(nèi)容要求：

以基礎(chǔ)性習(xí)題為主，促進(jìn)學(xué)生鞏固基礎(chǔ)知識(shí)，又要適當(dāng)進(jìn)行拓展，要設(shè)置一定量的探究性、實(shí)踐性作業(yè)，以提高學(xué)生綜合分析問題的能力，拓展性作業(yè)內(nèi)容每次約占作業(yè)量的80%。

限時(shí)作業(yè)可以嘗試教師指令性與學(xué)生自選性相結(jié)合的方式，特別是常規(guī)限時(shí)作業(yè)。即指令性2—4個(gè)題，自選性1—3個(gè)題。

3.作業(yè)時(shí)間：

①常規(guī)作業(yè)

6—9年級(jí)：語(yǔ)文、數(shù)學(xué)、英語(yǔ)課外作業(yè)書寫時(shí)間控制在30分鐘以內(nèi)。物理、化學(xué)課外作業(yè)書寫時(shí)間控制在20分鐘以內(nèi)。其他課外作業(yè)書寫時(shí)間控制在15分鐘以內(nèi)。

班主任要協(xié)調(diào)各科作業(yè)的布置情況，每天要相互溝通，不要扎堆，不要增加過重的學(xué)習(xí)負(fù)擔(dān)。

②雙休日作業(yè)

6—9年級(jí)：語(yǔ)文、數(shù)學(xué)、英語(yǔ)作業(yè)書寫時(shí)間控制在1小時(shí)以內(nèi)。物理、化學(xué)作業(yè)書寫時(shí)間控制在45分鐘以內(nèi)。其他課外作業(yè)書寫時(shí)間控制在30分鐘以內(nèi)。

各年級(jí)要在周四前將作業(yè)布置情況上報(bào)教導(dǎo)處。

③節(jié)假日作業(yè)

6—9年級(jí)：語(yǔ)文、數(shù)學(xué)、英語(yǔ)作業(yè)書寫時(shí)間控制在每天1小時(shí)以內(nèi)。物理、化學(xué)課外作業(yè)書寫時(shí)間控制在每天30分鐘以內(nèi)。其他課外作業(yè)書寫時(shí)間控制在每天20分鐘以內(nèi)。

4.作業(yè)批改

①講究及時(shí)細(xì)致批改作業(yè)。

批改要認(rèn)真細(xì)致，杜絕只寫“閱”字和日期等簡(jiǎn)單草率、不負(fù)責(zé)任的做法。另外應(yīng)及時(shí)，不積壓，原則上由教師全批全改和面批面改，或是在教師指導(dǎo)上的學(xué)生自改互改，一般情況上應(yīng)在上新課前把作業(yè)批改好發(fā)給學(xué)生。

②講究作業(yè)批改質(zhì)量。

做到“五有五必”，即有發(fā)必收，有收必批，有批必評(píng)，有評(píng)必透，有錯(cuò)必糾。作業(yè)批改要作好記載與分析并及時(shí)適當(dāng)點(diǎn)評(píng)，對(duì)典型性錯(cuò)誤、共性問題應(yīng)認(rèn)真、及時(shí)講評(píng)，要指導(dǎo)學(xué)生及時(shí)訂正錯(cuò)題導(dǎo)學(xué)批改，重視作業(yè)的及時(shí)講評(píng)反饋，要從作業(yè)中反思教學(xué)效果，以作業(yè)批改質(zhì)量促進(jìn)教學(xué)質(zhì)量的提升。

③講究作業(yè)批改規(guī)范化。

教師的批改一律用紅筆，批改要有對(duì)錯(cuò)符號(hào)、日期、等級(jí)（或評(píng)分、評(píng)語(yǔ)）等。批改要使用規(guī)范、統(tǒng)一的批改符號(hào)，符號(hào)醒目，使學(xué)生清楚地知道教師的批改意圖，有利于吸取經(jīng)驗(yàn)教訓(xùn)，改正錯(cuò)誤。成績(jī)?cè)u(píng)定采取等級(jí)制。

④講究用激勵(lì)性的批語(yǔ)給予鼓勵(lì)。

對(duì)于學(xué)生作業(yè)中的關(guān)鍵性錯(cuò)誤要予以修正或以紅線劃出，提倡必要時(shí)加眉批或總批予以說明、指導(dǎo)。批語(yǔ)力求準(zhǔn)確、精當(dāng)、具體，富有激勵(lì)性、啟發(fā)性、針對(duì)性和指導(dǎo)性。

⑤講究面批面改學(xué)生作業(yè)。

批改方式可多樣化，依班額、年級(jí)和學(xué)生差異，采取重點(diǎn)批改、全部批改、部分批改、當(dāng)面批改、學(xué)生自改、互改等形式，對(duì)邊緣學(xué)生、學(xué)困生的作業(yè)提倡采用面批面改方式，更有利于學(xué)生明確、彌補(bǔ)知識(shí)的缺漏。

二、限時(shí)作業(yè)的實(shí)施措施

1.加強(qiáng)領(lǐng)導(dǎo)，整體推進(jìn)。

高度重視，全員發(fā)動(dòng)，整體推進(jìn)，確保各個(gè)學(xué)科都能扎實(shí)開展。

分級(jí)領(lǐng)導(dǎo)：引領(lǐng)教師做好對(duì)重點(diǎn)工作的認(rèn)識(shí)，研究制定落實(shí)限時(shí)性作業(yè)，修訂教學(xué)常規(guī)實(shí)施要求。用規(guī)范引領(lǐng)教學(xué)改革。

業(yè)務(wù)校長(zhǎng)、教導(dǎo)主任：研究制定實(shí)施方案或細(xì)則，指導(dǎo)教研組制定出各學(xué)科具體的實(shí)施辦法，并對(duì)各教研組落實(shí)情況進(jìn)行抽查。

教研組長(zhǎng)：指導(dǎo)本學(xué)科所有教師做好限時(shí)性作業(yè)的落實(shí)，并對(duì)其檢查、總結(jié)，不斷創(chuàng)新工作的方法。

2.注重過程，量化管理。

實(shí)行“作業(yè)評(píng)估”制度，級(jí)部采取普查的方式，每周進(jìn)行一次作業(yè)評(píng)估，將作業(yè)設(shè)計(jì)質(zhì)量、作業(yè)完成情況、作業(yè)批閱及講評(píng)情況納入教師的業(yè)務(wù)考核之中。

三、限時(shí)作業(yè)布置、批改評(píng)價(jià)標(biāo)準(zhǔn)

學(xué)校教導(dǎo)處要不定期地對(duì)作業(yè)設(shè)計(jì)和批改情況全面檢查或抽查，將檢查和學(xué)生問卷調(diào)查結(jié)合認(rèn)定結(jié)果。主要檢查：作業(yè)量、批改情況、學(xué)生完成及落實(shí)情況情況，抽查時(shí)必須對(duì)上述三個(gè)方面做出結(jié)論：優(yōu)、良、中、差，檢查結(jié)果要納入教師業(yè)務(wù)量化考核，同時(shí)與評(píng)優(yōu)評(píng)先、考核掛鉤。
