【正文】 。[點(diǎn)撥]本題考查的是對說明方法理解運(yùn)用的綜合能力。目前，一般有哪幾種消除暖霧的方法？陜西的消霧作業(yè)屬于其中哪一種？[點(diǎn)撥]本題考查對文章說明內(nèi)容的歸納概括能力，其實(shí)就是對信息的捕捉、篩選、理解、加工。請認(rèn)真閱讀全文，簡要概括文章的思路。請根據(jù)文意，用一句話給“霧”下定義。2002年12月，陜西就是曾通過播散液態(tài)二氧化碳來改變霧的存在形式，使其變成雪后降落。三，人工擾動混合法。二，吸濕法。目前一般有三種消除暖霧的方法：一，加熱法。既然大霧給人們的生活帶來極大的不便，那么，人們能不能消除大霧呢？ 針對大霧形成的過程，我們可以進(jìn)行工人消霧，就是指用人工影響的方式消除局部區(qū)域內(nèi)的霧滴以提高能見度。據(jù)測定，霧滴中含酸、堿、鹽、胺、酚、塵埃、病原微生物等有害物質(zhì)的比例，比通常的大氣水滴高幾十倍。另外，霧對農(nóng)業(yè)生產(chǎn)也有危害，如果連續(xù)數(shù)天大霧，將使農(nóng)作物缺少光照，進(jìn)而影響農(nóng)作物生長，誘使病害發(fā)生，如小麥抽穗時(shí)遇上連續(xù)3天以上的大霧，就容易引起赤霉病。白晝的溫度一般比較高，空氣中可容納較多的水汽；但是到了夜晚，當(dāng)溫度低到空氣不能容納原先所有的水汽時(shí)，過剩的水汽便凝結(jié)成小水滴或小冰晶，浮游在近地面的大氣中，霧就形成了。大霧到底是怎樣形成的呢？讓我們來看生活中的一個(gè)現(xiàn)象：在做飯的時(shí)候，大家肯定能看到鍋上方總是有霧氣產(chǎn)生，大霧的形成和它形成的原理相同，只是形成的范圍大，維持的時(shí)間長而已。當(dāng)?shù)蛯哟髿庵械乃_(dá)到飽和狀態(tài)時(shí)，水汽凝結(jié)物懸浮在空氣中形成霧茫茫的天氣，并使能見度的水平距離小于1千米，氣象上把這種天氣稱為霧。（2）“重要信息”具體指：a、與題目要求相關(guān)的內(nèi)容；b、體現(xiàn)文章的主要觀點(diǎn)、反映作者態(tài)度主張的內(nèi)容；c、表述新信息的內(nèi)容（新發(fā)現(xiàn)、新概念、新進(jìn)展）等；d、對新發(fā)現(xiàn)、新概念等新的知識進(jìn)行解說的內(nèi)容。準(zhǔn)確篩選、提取文中的信息進(jìn)行歸納概括再表述。[金點(diǎn)巧指]：歸納內(nèi)容要點(diǎn)，概括文意、層意和段落（1）首先要準(zhǔn)確把握文段中的中心句和說明的內(nèi)容。[復(fù)習(xí)目標(biāo)]：歸納內(nèi)容要點(diǎn)，概括文意、層意和段落。 wonder how he dare to day such ．happen to do so(just)happened that…不能用于進(jìn)行時(shí)態(tài)。有人稱、數(shù)和時(shí)態(tài)的變化。沒有人稱和數(shù)的變化,其時(shí)態(tài)只有現(xiàn)在時(shí)和過去時(shí)。 stayed single all his + O +Noun(as .) awayColumbus discovered America in down: to write down something so that you have a record of it: I want to set down my feelings on verbal phrases of “set”set aside: to keep some money or time for a special purpose set off: to start to go somewhere/ to cause a explosion set out: to start a journey/ to talk about something in an organized way set up: to start an organization/ to build something / indoors Don’t stay indoors since the weather is so They speak well of on purposeI came here on purpose to see in order toIn order to catch the train , she hurried through her too much/ much too entirelyFor him, this will be an entirely new in one’s power / out of one’s powers 15 it was the first/second time that …It is the first time that he has been in this was the second time that he had made the same mistakes 16 face to faceI rushed out of the office and found myself face to face with the adv.“過于；…得多” ,表示程度，經(jīng)常與too或形容詞、副詞的比較級連用?！锇鍟O(shè)計(jì)一、“印度支那問題”二、從“特種戰(zhàn)爭”到局部戰(zhàn)爭 ★教學(xué)反思：第四篇：英語：unit1《Friendship》教案2(新人教必修1)（精選）Period 3 Learning about language Teaching aims: discover and learn to use some words and enable students to rewrite sentences using direct or indirect speech learn more information about cultivate the spirit of cooperation, selfteaching and procedures: Step 1 Revision something about “Anne’s best friend” by using some TrueorFalse sentences 1)A friend would laugh at you.（）2)Anne lived in Amsterdam in the Netherlands during World War II.（）3)She and her family hid away for one year before they were discovered.（）4)She kept a diary as others did.（）5)She was fond of nature.（）6)She stayed awake in the night because she couldn’t sleep well.（）7)She couldn’t go out as she liked.（） the sentences students think wonderful or difficult to sentences 1)She and her family hid away for nearly twentyfive months before they were )I wonder if it’s because I haven’t been
