【正文】 要求考生設(shè)計(jì)實(shí)驗(yàn)方案,拓展實(shí)驗(yàn)探究方法(如:先實(shí)驗(yàn)假設(shè)、后實(shí)驗(yàn)方案、再實(shí)驗(yàn)評(píng)價(jià)、最后實(shí)驗(yàn)拓展),注重考生的實(shí)驗(yàn)探究設(shè)計(jì)能力考查。5.選擇題中同分異構(gòu)體考查1mol酯水解生成1mol羧酸和2mol醇(或生成2mol羧酸和1mol醇).6.化學(xué)工藝流程題。播出時(shí)使用專門的電影電視轉(zhuǎn)換機(jī)將膠片上的光信號(hào)變成電信號(hào)發(fā)送出去。用電影膠片攝制、提供給電視臺(tái)播出的故事片。從技術(shù)標(biāo)準(zhǔn)方面來看,相對(duì)于一般電視劇,電視電影應(yīng)該是更精美的制作。每個(gè)鏡頭所表現(xiàn)的時(shí)間和現(xiàn)實(shí)的時(shí)間是同步的(升格、降格除外),電影是由一個(gè)個(gè)鏡頭剪接而成的,兩個(gè)鏡頭之間為時(shí)間的跳躍提供極大的自由。其次,由 于這種手法是幾條線索平列表現(xiàn),相互烘托,形成對(duì)比,易于產(chǎn)生強(qiáng)烈的藝術(shù)感染效果。這就是所謂庫里肖夫效應(yīng)。蘇聯(lián)電影導(dǎo)演列夫.庫里肖夫?yàn)榱伺迕商娴牟⒘凶饔茫隽艘豁?xiàng)有名的鏡頭剪接實(shí)驗(yàn)。① 分別寫出水楊酸和苯酚完全燃燒的化學(xué)方程式(有機(jī)物可用分子式表示)。② B + DE:_____________________________________________________。① 含有苯環(huán); ② 能發(fā)生銀鏡反應(yīng),不能發(fā)生水解反應(yīng); ③ 在稀NaOH溶液中,1 mol該同分異構(gòu)體能與2 mol NaOH發(fā)生反應(yīng); ④ 只能生成兩種一氯代產(chǎn)物。29.(21分)薩羅(Salol)是一種消毒劑,它的分子式為C13H19O3,其分子模型如下圖所示(圖中球與球之間的連線代表化學(xué)鍵,如單鍵、雙鍵等):⑴ 根據(jù)右圖模型寫出薩羅的結(jié)構(gòu)簡(jiǎn)式:___________________________。⑴ A是制取CO2的裝置。寫出該化合物的名稱及化學(xué)式_________________________________________________。L_C.L1的CH3COOH溶液中存在如下電離: CH3COOHCH3COO+H+ 對(duì)于該平衡,下列敘述正確的是: A.加入水時(shí),平衡向逆反應(yīng)方向移動(dòng) B.加入少量NaOH固體,平衡向正反應(yīng)方向移動(dòng) C.加入少量HCl溶液,溶液中c(H+)減小 D.加入少量CH3COONa固體,平衡向正反應(yīng)方向移動(dòng)12.茉莉醛具有濃郁的茉莉花香,其結(jié)構(gòu)簡(jiǎn)式如下所示:CH CH CHO CH2(CH2)CH3關(guān)于茉莉醛的下列敘述錯(cuò)誤的是: A.在加熱和催化劑作用下,能被氫氣還原 B.能被高錳酸鉀酸性溶液氧化 C.在一定條件下能與溴發(fā)生取代反應(yīng) D.不能與氫溴酸發(fā)生加成反應(yīng)13.由硫酸鉀、硫酸鋁和硫酸組成的混合溶液,其PH=1,c(Al3+)=我覺得我的學(xué)校生活是忙碌而開心。在早上,我有四節(jié)課,在下午我有三節(jié)課?;氐轿业尼烎~的地方,我發(fā)現(xiàn)我的釣竿漂浮在水面上。投擲釣竿,我沖了一箭,跳進(jìn)河里,游向男孩很快。我fimnd一個(gè)最優(yōu)惠一點(diǎn)。你覺得他怎么樣?高一英語作文:A Day in My Summer Vacation Last summer I spent a twoweek vacation at my aunt39。然后他送她回家。他總是樂意幫助我們。他問我們聽,讀,說,寫。在他的課上,我們感到非常高興。我們都叫他“朱先生。這是一個(gè)很小的,但也有許多花和樹。有一張桌子旁邊的床上。讓樹,花和草回到我們的家。我們感到很難過。這么多的樹木被砍伐,更多的大型城市將設(shè)立。有很多大或小,紅色或綠色,美麗的花園,在我們身邊。高一英語作文:我們可愛的家 Our Lovely HomeWe are now living in a mon is the provides us with enough food, enough water and enough living we must do everything to protect are lots of big or small, red or green, beautiful gardens around there are still some other lands bare of grasses or trees on the people may ask why not led all lands covered with trees, flowers and grasses?

Yes!Our environment is being polluted faster than nature and man’s efforts can is bring us more people, and more people will bring us more many trees will be cut down, and more large cities will be set of waste material, in return, is produced and harms the some experts declare that the balance of nature is being survival of man is in feel really sad about can we do to solve this problem? We must forbid cutting down trees and forbid killing animals and pouring waste water into rivers and so ’ll never destroy the balance of ’s get along well with all the trees, flowers and grasses e back to our we have only one homethe 。考試時(shí)作弊,他們有時(shí)為了得到更好的結(jié)果,請(qǐng)家長(zhǎng)和老師。t work hard at their when taking examinations, they sometimes cheat in order to get better results to please their parents and my opinion, it is wrong to cheat in examinations because it breaks the rules of students should be honest and try
