Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews.

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:?

You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers!

人教版新課標小學數(shù)學一年級下冊人民幣的簡單計算教案
人民幣的簡單計算是在對人民幣的認識后，是人民幣的再進一步的認識。本節(jié)課的主要知識點主要有三個：一人民幣單位間的換算、二進行簡單的計算，三是知道商品價格的表示形式。同時通過這節(jié)課的學習，逐漸培養(yǎng)交往和社會實踐能力，體會人民幣在社會生活商品交換中的作用。為了達成以上的一些目標我是這樣設(shè)計這節(jié)課。一、從學生經(jīng)驗入手直接引入商品價格，在學生回憶商品價格的表示方法中，喚醒學生的思緒，使學生覺得在所學的知識與實際生活的聯(lián)系。讓學生體驗到數(shù)學與日常生活的密切聯(lián)系。二、在操作中完成進率的換算。進率的換算在教學是一個重點也是難點，為此我在教學上通過不同的的付錢方法，深刻體會，這樣的教學讓說不清的關(guān)系，在操作講解中得以內(nèi)化。學生學了也不易忘記。

三、解題和介紹創(chuàng)作背景。"裝在套子里的人"是指生活和思想上都有某種框框，不敢越雷池一步的人，小說中的主人公就是這樣一個人物，他是沙皇專制主義的產(chǎn)物。現(xiàn)在，別里科夫已成為頑固守舊，害怕變革，阻礙社會發(fā)展的人的代名詞。我們學習這篇課文，必須把握創(chuàng)作的時代背景：19世紀末期的俄國正是農(nóng)奴制度崩潰、資本主義迅速發(fā)展、沙皇專制極端反動和無產(chǎn)階級革命逐漸興起的時期。沙皇政府面臨著日益高漲的革命形勢，極力加強反動統(tǒng)治，沙皇政府的忠實衛(wèi)道士，也極力維護沙皇的反動統(tǒng)治，仇視和反對一切社會變革。作者寫這篇小說就是為了揭露和諷刺這種人丑惡的本質(zhì)。四、結(jié)構(gòu)分析明確：故事的主要情節(jié)是別里科夫的戀愛以及最后失敗，按照情節(jié)的發(fā)展可以把課文分成三部分：（一）介紹別里科夫的外表、生活習性和思想性格（第1-4段）。（二）別里科夫與華連卡戀愛以及最后失?。ǖ?段至倒數(shù)第3段）。（三）埋葬別里科夫，但生活中還有許多"別里科夫"（最后兩段）。
人教版高中語文必修5《談中國詩》教案
教師提示：1.這句話的本體不是一般意義上的“中國詩”，即不是指中國詩歌中的某一類作品或某位詩人的作品，而是指中國詩的發(fā)展特點。早熟，是指“純粹的抒情詩的精髓和峰極，在中國詩里出現(xiàn)得異常之早”；早衰，是指“中國詩一蹴而至崇高的境界，以后就缺乏變化，而且逐漸腐化”(腐化，是對詩的思想內(nèi)容和藝術(shù)價值而言的)。這句話，借助比喻和比喻中的對比(“早熟”與“早衰”)，從詩歌發(fā)展的角度，簡要地說明了中國詩的藝術(shù)特征和由此產(chǎn)生的負面影響。2.這句話有兩層意思：一是借梵文的《百喻經(jīng)》闡釋中國的藝術(shù)和思想體構(gòu)上的缺欠，旨在批評；二是點明造成這種缺欠的根本原因?！耙粋€印度愚人要住三層樓而不許匠人造底下兩層”這樣的建筑物就是“飄飄凌云的空中樓閣”，作者以此作喻，批評中國的藝術(shù)和思想體構(gòu)缺乏嚴密的邏輯性，往往脫離客觀實際，沒有堅實的基礎(chǔ)，其結(jié)果必定影響藝術(shù)的健康、穩(wěn)定地發(fā)展。
