      6.小學(xué)人教版六年級(jí)上冊(cè)復(fù)習(xí)資料,包括:語(yǔ)文,數(shù)學(xué),英語(yǔ),科學(xué)

      科學(xué):小學(xué)六年級(jí)科學(xué)上冊(cè)復(fù)習(xí)資料 第一單元 工具和機(jī)械 一、使用工具 1. 機(jī)械 是能使我們省力或方便的裝置。

      2.螺絲刀、釘錘、剪刀這些機(jī)械構(gòu)造很簡(jiǎn)單,又叫 簡(jiǎn)單機(jī)械 。 3.用螺絲刀可以比較方便的把螺絲釘從木頭中取出,用羊角榔頭可以比較方便的把鐵釘從木頭中取出。

      不同的工具有不同的用途。 二、杠桿的科學(xué) 1.像撬棍這樣的簡(jiǎn)單機(jī)械叫做 杠桿 。

      2.杠桿上有三個(gè)重要的位置:支撐著杠桿,使杠桿能?chē)@著轉(zhuǎn)動(dòng)的位置叫 支點(diǎn) ;在杠桿上用力的位置叫 用力點(diǎn) ;杠桿克服阻力的位置叫 阻力點(diǎn) 。 3.當(dāng)阻力點(diǎn)到支點(diǎn)的距離小于用力點(diǎn)到支點(diǎn)的距離時(shí),杠桿 省力 ;當(dāng)阻力點(diǎn)到支點(diǎn)的距離大于用力點(diǎn)到支點(diǎn)的距離時(shí),杠桿 費(fèi)力;當(dāng)阻力點(diǎn)到支點(diǎn)的距離等于用力點(diǎn)到支點(diǎn)的距離時(shí),杠桿 不省力也不費(fèi)力 。

      4.杠桿尺上有支點(diǎn),左右兩邊都有到支點(diǎn)距離的標(biāo)記,是研究杠桿作用的好工具。 5.用三種不同的方法掛鉤碼,使杠桿尺保持平衡,把你的方法在下圖畫(huà)出來(lái)。

      三、杠桿類(lèi)工具的研究 1.省力的是(鐵片、羊角榔頭、老虎鉗、開(kāi)瓶器 ),費(fèi)力的是(火鉗、鑷子)。 2.常用的杠桿類(lèi)工具中羊角榔頭、老虎鉗、開(kāi)瓶器是省力杠桿;火鉗、筷子、鑷子是費(fèi)力杠桿;蹺蹺板、天平、訂書(shū)器是不省力也不費(fèi)力杠桿。

      有些杠桿類(lèi)工具設(shè)計(jì)成費(fèi)力的是因?yàn)樗蟹奖愕暮锰帲ㄈ纾鸿囎印⑨烎~(yú)竿等)。 3.“秤砣雖小,能壓千斤”,那是桿秤利用了 杠桿 原理的結(jié)果(提繩是支點(diǎn),秤砣是用力點(diǎn),稱(chēng)重物處是阻力點(diǎn))。

      4.我們身體上的前臂骨像是一根杠桿,肘關(guān)節(jié)是支點(diǎn),手握物體處是阻力點(diǎn),上臂的肱二頭肌處就是用力點(diǎn)。 5.阿基米德曾說(shuō):“只要在宇宙中給我一個(gè)支點(diǎn),我能用一根長(zhǎng)長(zhǎng)的棍子把地球撬起來(lái)?!?/p>

      這里的棍子相當(dāng)于杠桿。 四、輪軸的秘密 1.像水龍頭這樣,輪子和軸固定在一起轉(zhuǎn)動(dòng)的機(jī)械,叫做 輪軸 。

      螺絲刀是輪軸類(lèi)工具,它的刀柄是 輪 ,刀桿是 軸 。 2.在輪上用力帶動(dòng)軸運(yùn)動(dòng)時(shí) 省 力;在軸上用力帶動(dòng)輪運(yùn)動(dòng)時(shí) 費(fèi) 力。

      3.輪軸可以 省 力,輪越大,用輪帶動(dòng)軸轉(zhuǎn)動(dòng)就越 省 力。所以螺絲刀的刀柄總是比刀桿要 粗 一些。

      4.扳手套在螺帽上組成了 輪軸 ,這時(shí)整個(gè)扳手是 輪 ,螺帽部分是 軸 。 5.生活中的輪軸:水龍頭、門(mén)鎖把手、汽車(chē)方向盤(pán)、扳手、轆轤等。

      五、定滑輪和動(dòng)滑輪 1.像旗桿頂部的滑輪那樣,固定在一個(gè)位置轉(zhuǎn)動(dòng)而不移動(dòng)的滑輪叫做 定滑輪 ;定滑輪可以 改變用力方向 ,但不能 省力 。 2.像塔吊的吊鉤上可以隨著重物一起移動(dòng)的滑輪叫做 動(dòng)滑輪 ;動(dòng)滑輪可以 省力 ,但不能 改變用力方向 。

      3.動(dòng)滑輪可以省力,但不能改變用力方向。 *力的大小用測(cè)力計(jì)來(lái)測(cè)量,牛頓是力的單位,用字母“N”表示。

      六、滑輪組 1.把定滑輪和動(dòng)滑輪組合在一起使用,就構(gòu)成了滑輪組。使用滑輪組既能省力,又能 改變用力方向 。

      2.一個(gè)定滑輪和一個(gè)動(dòng)滑輪組合在一起為一個(gè) 最簡(jiǎn)單的滑輪組 ,滑輪組的組數(shù)越多,就越 省力 。 3.起重機(jī)運(yùn)用了滑輪組。

      4. ①名稱(chēng):定滑輪_ ②名稱(chēng):動(dòng)滑輪 ③名稱(chēng):滑輪組 ④名稱(chēng):滑輪組 所起的作用: 所起的作用: 所起的作用: 所起的作用: ??? 改變用力方向 能省力 既能省力 既能省力 不能省力 不能改變用力方向 又能改變用力方向 又能改變用力方向 如果分別用它們提起相同重量的物品50千克,最省力的是( ④ ),其次是( ② 、③ ),不省力的是( ① )。 七、斜面的作用 1.像搭在汽車(chē)車(chē)廂上的木板那樣的簡(jiǎn)單機(jī)械,叫做 斜面 。

      2.斜面能 省 力,斜面的坡度越 小 越省力,坡度越 大 越不省力。 3.生活中應(yīng)用斜面的地方很多,如 “S” 形的盤(pán)山公路、各種斜坡、各種刀刃、螺絲釘?shù)穆菁y,高架橋的引橋等 。

      4.螺絲釘?shù)穆菁y是斜面的變形。同樣粗細(xì)的螺絲釘,螺紋越密,旋進(jìn)木頭時(shí)越 省力 。

      5. 研究的問(wèn)題:斜面的坡度對(duì)省力多少有影響嗎? 我的假設(shè): 斜面的坡度對(duì)省力多少有影響;斜面的坡度越小越省力。 需要改變的條件: 斜面的坡度大?。緣K的高低) 不改變的條件: 同一個(gè)重物,同一塊木板,提升重物的速度; 實(shí)驗(yàn)方法:(1)把一塊木板分別搭在高低不同的木塊上,做成幾個(gè)坡度不同的斜面; (2)用測(cè)力計(jì)勾住重物,用同樣的速度沿不同坡度的斜面提升重物;(3)記錄下在每種斜面上用力的大小,并進(jìn)行比較。

      八、自行車(chē)上的簡(jiǎn)單機(jī)械 1.自行車(chē)運(yùn)用了 杠桿(如:剎車(chē)、車(chē)鈴的按鈕) 、輪軸 (如:把手、腳蹬) 、斜面(如:螺絲釘) 等簡(jiǎn)單機(jī)械的原理。這些簡(jiǎn)單機(jī)械起到省力或方便的作用。

      2.自行車(chē)上齒輪轉(zhuǎn)動(dòng)的快慢與齒輪大小的關(guān)系是:大齒輪帶動(dòng)小齒輪轉(zhuǎn)動(dòng)時(shí),小齒輪轉(zhuǎn)動(dòng)比大齒輪 快 ;小齒輪帶動(dòng)大齒輪轉(zhuǎn)動(dòng)時(shí),大齒輪轉(zhuǎn)動(dòng)比小齒輪 慢 。 * 綜合:請(qǐng)把下面物品和應(yīng)用的簡(jiǎn)單機(jī)械原理用線連起來(lái)。

      斜面 輪軸 杠桿 滑輪 螺絲刀 鑷子 螺絲釘 水龍頭 起重機(jī) 第二單元 形狀與結(jié)構(gòu) 一、抵抗彎曲 1.房屋、橋梁結(jié)構(gòu)中有直立的“柱子”和橫放的“橫梁”,橫梁比柱子容易彎曲和斷裂,所以要提高橫梁的抗彎曲能力。 2.提高材料的抗彎曲能力,我們可以通過(guò)增加材料的寬度,還可以增加材料的厚度或改變材料的形狀。

      3.紙的寬度增加,抗彎曲能力也會(huì)增加;紙的厚度增加,抗彎曲能力會(huì)大大增加。 4.研究的問(wèn)題:紙的寬度與抗彎。

      7.人教版六年級(jí)上冊(cè)英語(yǔ)復(fù)習(xí)資料有不

      六年級(jí)上冊(cè)知識(shí)點(diǎn)Unit 1 How do you go to school?主要單詞:by plane 坐飛機(jī) by ship 坐輪船 on foot步行by bike 騎自行車(chē) by bus 坐公共汽車(chē) by train 坐火車(chē) traffic lights交通燈 traffic rules交通規(guī)則 Stop at a red light 紅燈停 Wait at a yellow light 黃燈等 Go at a green light 綠燈行主要句子:How do you go to school?你怎么去上學(xué)?Usually I go to school on foot. Sometimes I go by bus.通常我步行去上學(xué)。

      有時(shí)候騎自行車(chē)去。How can I get to Zhongshan Park ?我怎么到達(dá)中山公園?You can go by the No. 15 bus.你可以坐15路公共汽車(chē)去。

      知識(shí)點(diǎn):1、There are many ways to go somewhere.到一個(gè)地方去有許多方法。這里的ways一定要用復(fù)數(shù)。

      因?yàn)閠here are是There be句型的復(fù)數(shù)形式。2、get to到達(dá).關(guān)本單元我們還要學(xué)習(xí)與get相關(guān)的短語(yǔ):get on 上車(chē) get off下車(chē)3、on foot 步行乘坐其他交通工具大都可以用介詞by?, 但是步行只能用介詞on 。

      4、go to school的前面絕對(duì)不能加the,這里是固定搭配。5、USA 和 US 都是美國(guó)的意思。

      另外America也是美國(guó)的意思。6 go to the park前面一定要加the.如果要去的地方有具體的名字,就不能再加the , 如果要去的地方?jīng)]有具體名字,由要在前面加the. go to school除外。

      7、How do you go to ??你怎樣到達(dá)某個(gè)地方?如果要問(wèn)的是第三人稱(chēng)單數(shù),則要用:How does he/she?go to ??8、反義詞:2 get on(上車(chē))---get off(下車(chē)) near(近的)—far(遠(yuǎn)的) fast(快的)—slow(慢的) because(因?yàn)椋獁hy(為什么)same(相同的)—different(不同的)9、近義詞:see you---goodbye sure---certainly---of course 10、頻度副詞:always 總是,一直 usually 通常 often經(jīng)常 sometimes 有時(shí)候 never 從來(lái)不Unit 2 Where is the science museum?主要單詞:library 圖書(shū)館 post office 郵局 hospital醫(yī)院 cinema 電影院 bookstore書(shū)店 science museum科學(xué)博物館 turn left向左轉(zhuǎn) turn right 向右轉(zhuǎn) go straight 直行 north北 south南 east東 west西主要句子:Where is the cinema, please? 請(qǐng)問(wèn)電影院在哪里?It's next to the hospital. 它與醫(yī)院相鄰。Turn left at the cinema, then go straight. It's on the left.在電影院向左轉(zhuǎn),然后直行。

      它在左邊。知識(shí)點(diǎn):1、near 表示在附近,next to 表示與?相鄰。

      它的范圍比near小。2、電影院在英語(yǔ)中稱(chēng)為“cinema”,在美語(yǔ)中稱(chēng)為movie theatre.3、for 表示持續(xù)多長(zhǎng)時(shí)間,當(dāng)表示做某事多長(zhǎng)時(shí)間都要用for. 如:Walk east for 5 minutes.4、當(dāng)表示某個(gè)地方在另一個(gè)地方的哪一方向時(shí),要用介詞of。

      如:the hospital is east of the cinema. 醫(yī)院在電影院的東邊。5、表示在哪兒轉(zhuǎn)時(shí),用介詞at。

      如:Turn left at the bank。在銀行左轉(zhuǎn)。

      3 6、find表示“找到”,強(qiáng)調(diào)找的結(jié)果。Look for 表示“尋找”,強(qiáng)調(diào)找的過(guò)程。

      7、英文的書(shū)信與中文的書(shū)信不完全一樣:開(kāi)頭:英語(yǔ)是在人稱(chēng)后面加逗號(hào),中文是加冒號(hào)。正文:英語(yǔ)是頂格寫(xiě),中文要空兩個(gè)格。

      結(jié)尾:英語(yǔ)的落款與人名是頂格而且是分開(kāi)寫(xiě)的。中文則是另起一行,放在一起且稍靠后一點(diǎn)兒的地方。

      8、近義詞:bookstore==bookshop 書(shū)店 go straight==go down直行after school==after class 放學(xué)后9、反義詞或?qū)?yīng)詞:here (這里)---there(那里)east(東)---west(西) north(北)---south(南)left(左)---right(右) get on (上車(chē))---get off(下車(chē))10、in the front of?表示在?的前面,是指在該地方的范圍內(nèi),in front of而則表示在該地方的范圍外。如:in front of our classroom是指在教室的外面而且在教室的前面。

      而in the front of classroom則是指在教室里的前面。11. be far from?表示離某地遠(yuǎn). be 可以是am , is ,are。

      如:I am far from school now. 我現(xiàn)在離學(xué)校很遠(yuǎn)。My home is not far from school.我家離學(xué)校不遠(yuǎn)。

      Unit 3 What are you going to do ?主要單詞:this morning 今天上午 this afternoon 今天下午this evening 今天晚上 next week 下周tomorrow 明天 tonight 今晚post card 明信片 comic book漫畫(huà)書(shū) newspaper報(bào)紙主要句子:What are you going to do on the weekend?你周末打算做什么?I'm going to visit my grandparents this weekend.這個(gè)周末我打算去看望我的外祖父母。Where are you going this afternoon? 你今天下午打算去哪里?I'm going to the bookstore.我打算去書(shū)店。

      What are you going to buy?你打算去買(mǎi)什么?I'm going to buy a comic book。我打算去買(mǎi)一本漫畫(huà)書(shū)。

      知識(shí)點(diǎn):1、What are you going to do?你想做什么?詢問(wèn)他人在未來(lái)的打算。Be going to 后面要跟動(dòng)詞的原形。

      2、this evening 和 tonight的區(qū)別:this evening指的是今天晚上睡覺(jué)以前的時(shí)間,一般指晚上十二點(diǎn)以前。而tonight指的是今晚,一般是指一整晚的時(shí)間,通宵。

      3、部分疑問(wèn)代詞的意義與用法:(1)What 什么。用來(lái)問(wèn)是什么,做什么,叫什么,什么樣等等。

      如:What is your name? 你的名字叫什么?What is your father? 你爸爸是干什么的?What is your hobby?你的愛(ài)好是什么?What is your favourite food?你最喜愛(ài)的食物是什么?What's your math teacher like? 你的數(shù)學(xué)老師長(zhǎng)得。
