高二第一學(xué)期的英語期末復(fù)習(xí)備考計(jì)劃復(fù)習(xí)目標(biāo):根據(jù)高二學(xué)生對所學(xué)的知識掌握情況,進(jìn)行系統(tǒng)性歸納和總結(jié),提高綜合運(yùn)用能力。
復(fù)習(xí)重點(diǎn):以必修修五知識為主要復(fù)習(xí)內(nèi)容。
復(fù)習(xí)要求:
1、注意復(fù)習(xí)的全面性。
2、注意重難點(diǎn)。
3、注意密度、合理分配時(shí)間。
4、以練為主,綜合練習(xí)為主。
復(fù)習(xí)措施:
1、根據(jù)考試類型題,有系統(tǒng)的針對性的進(jìn)行專項(xiàng)復(fù)習(xí)的針對性練習(xí)和反饋的鞏固練習(xí)。
2、復(fù)習(xí)過程中進(jìn)行階段性綜合練習(xí)。
3、在復(fù)習(xí)過程中要注重培優(yōu)輔差工作。同時(shí)及時(shí)了解學(xué)生學(xué)習(xí)的思想動(dòng)向,給予適當(dāng)?shù)墓膭?lì)和信心。
4、加強(qiáng)單詞的朗讀和默寫,給學(xué)生明確的任務(wù),使他們也能盡自己最大能力過好單詞關(guān)。將詞組復(fù)習(xí)與單詞分類復(fù)習(xí)相聯(lián)系。在復(fù)習(xí)過程中,要緊緊抓住教材中的閱讀,做到精讀和導(dǎo)讀相結(jié)合,在較短時(shí)間內(nèi)起到良好的教學(xué)效果。把單詞、詞組、句子和閱讀作為一個(gè)有機(jī)整體,在復(fù)習(xí)過程中將它們緊密聯(lián)系起來,合理安排復(fù)習(xí)內(nèi)容,提高學(xué)生整體運(yùn)用知識的能力。
5、堅(jiān)持每節(jié)課前適量單詞的聽寫,加強(qiáng)他們認(rèn)真、細(xì)心的學(xué)習(xí)態(tài)度,鞏固知識的運(yùn)用等能力和增強(qiáng)學(xué)習(xí)成功的信心。
復(fù)習(xí)具體計(jì)劃:
1、認(rèn)記所歸納的詞組
2、歸納語法
3、進(jìn)行針對性的專項(xiàng)練習(xí)(1)單項(xiàng)選擇(2)完型填(3)閱讀理解

高二化學(xué)下冊知識點(diǎn)(一)
有機(jī)物的溶解性
(1)難溶于水的有:各類烴、鹵代烴、硝基化合物、酯、絕大多數(shù)高聚物、高級的(指分子中碳原子數(shù)目較多的,下同)醇、醛、羧酸等。
(2)易溶于水的有:低級的[一般指N(C)≤4]醇、(醚)、醛、(酮)、羧酸及鹽、氨基酸及
鹽、單糖、二糖。(它們都能與水形成氫鍵)。(3)具有特殊溶解性的:
①乙醇是一種很好的溶劑,既能溶解許多無機(jī)物,又能溶解許多有機(jī)物,所以常用乙醇
來溶解植物色素或其中的藥用成分,也常用乙醇作為反應(yīng)的溶劑,使參加反應(yīng)的有機(jī)物和無機(jī)物均能溶解,增大接觸面積,提高反應(yīng)速率。例如,在油脂的皂化反應(yīng)中,加入乙醇既能溶解NaOH,又能溶解油脂,讓它們在均相(同一溶劑的溶液)中充分接觸,加快反應(yīng)速率,提高反應(yīng)限度。
②苯酚:室溫下,在水中的溶解度是9.3g(屬可溶),易溶于乙醇等有機(jī)溶劑,當(dāng)溫度高高中化學(xué)選修5于65℃時(shí),能與水混溶,冷卻后分層,上層為苯酚的水溶液,下層為水的苯酚溶液,振蕩后形成乳濁液。苯酚易溶于堿溶液和純堿溶液,這是因?yàn)樯闪艘兹苄缘拟c鹽。
③乙酸乙酯在飽和碳酸鈉溶液中更加難溶,同時(shí)飽和碳酸鈉溶液還能通過反應(yīng)吸收揮發(fā)出的乙酸,溶解吸收揮發(fā)出的乙醇,便于聞到乙酸乙酯的香味。
④有的淀粉、蛋白質(zhì)可溶于水形成膠體。蛋白質(zhì)在濃輕金屬鹽(包括銨鹽)溶液中溶解度減小,會析出(即鹽析,皂化反應(yīng)中也有此操作)。但在稀輕金屬鹽(包括銨鹽)溶液中,蛋白質(zhì)的溶解度反而增大。
⑤線型和部分支鏈型高聚物可溶于某些有機(jī)溶劑,而體型則難溶于有機(jī)溶劑。
⑥氫氧化銅懸濁液可溶于多羥基化合物的溶液中,如甘油、葡萄糖溶液等,形成絳藍(lán)色溶液。
高二化學(xué)下冊知識點(diǎn)(二)
既能與強(qiáng)酸,又能與強(qiáng)堿反應(yīng)的物質(zhì)
(1)2Al+6H+==2Al3++3H2↑
2Al+2OH+2H2O==2AlO2+3H2↑
(2)Al2O3+6H+==2Al3++3H2O
Al2O3+2OH==2AlO2+H2O
(3)Al(OH)3+3H+==Al3++3H2O
Al(OH)3+OH==AlO2+2H2O
(4)弱酸的酸式鹽,如NaHCO3、NaHS等等
NaHCO3+HCl==NaCl+CO2↑+H2ONaHCO3+NaOH==Na2CO3+H2O
NaHS+HCl==NaCl+H2S↑NaHS+NaOH==Na2S+H2O
(5)弱酸弱堿鹽,如CH3COONH4、(NH4)2S等等
2CH3COONH4+H2SO4==(NH4)2SO4+2CH3COOHCH3COONH4+NaOH==CH3COONa+NH3↑+H2O(NH4)2S+H2SO4==(NH4)2SO4+H2S↑(NH4)2S+2NaOH==Na2S+2NH3↑+2H2O
(6)氨基酸,如甘氨酸等
H2NCH2COOH+HCl→HOOCCH2NH3ClH2NCH2COOH+NaOH→H2NCH2COONa+H2O
