4、一篇寫小蝦生活習(xí)性的文章。通過觀察小蝦吃食、打架等細(xì)節(jié)的描寫，突出小蝦有趣、脾氣不好兩個(gè)特點(diǎn)，表達(dá)了我對小蝦的喜愛之情。課文比較淺顯易懂，以學(xué)習(xí)生字詞語，學(xué)習(xí)課文，了解小蝦的有趣之處，體會(huì)作者對小蝦的喜愛之情為目標(biāo)，進(jìn)而學(xué)習(xí)作者的觀察方法，為后面的作文教學(xué)打基礎(chǔ)。在第一課時(shí)的教學(xué)中，學(xué)生已掃清了字詞障礙，初讀了課文，了解了課文的主要內(nèi)容，理清了文章脈落。在第二課時(shí)的學(xué)習(xí)中，我抓住小蝦的樣子、吃食有趣、脾氣不好三個(gè)重點(diǎn)段落來引導(dǎo)學(xué)習(xí)。在教學(xué)“吃食有趣”這段時(shí)，我設(shè)計(jì)了以下環(huán)節(jié)：1、小蝦怎樣吃東西？找出相關(guān)的句子。（小蝦真有趣。它們吃東西的時(shí)候非常小心，總是先用鉗子輕輕碰一下食物，然后迅速后退，接

5、著再碰一下，又后退，直到覺得沒有危險(xiǎn)了，才用兩個(gè)鉗子捧著食物吃起來。）2、標(biāo)畫出描寫小蝦吃東西的動(dòng)詞。（碰 后退 再碰 又后退 捧著 吃）3、連接這些動(dòng)詞的詞有哪些？（先 然后 接著 又 才）4、用自己的語言描述小蝦吃東西的樣子。5、從這些詞語中你體會(huì)到了什么？（動(dòng)作敏捷 警惕性高 非常小心 很有趣）6、吃飽了的小蝦在做什么？ 7、誰能模仿一下小蝦吃食的樣子呢？8、再次品讀，讀出小蝦吃東西的有趣。 在“誰能模仿一下小蝦吃食的樣子呢？”這一環(huán)節(jié)的教學(xué)中，由于這是我給學(xué)生上的第一堂語文課，學(xué)生對我還不熟悉，初始有點(diǎn)膽怯，不敢參與，我即興表演了幾個(gè)動(dòng)作，可能我的動(dòng)作有點(diǎn)夸張，還沒表演完，就有一部分學(xué)

6、生笑起來了，還有幾個(gè)學(xué)生舉起了手，有一個(gè)學(xué)生的手舉得很高，我以為他是要迫不及待地表演一下，沒想到，他站起來說： “老師，你怎么鬼鬼崇崇的？像個(gè)小偷？”我一下子就笑開了，“那你能表演的更形象嗎？”這個(gè)學(xué)生自信地走上臺(tái)，惟妙惟肖地表演了小蝦吃食的樣子，甚至臉上都有了表情?！袄蠋?，我還能表演小蝦吃飽了的樣子！”學(xué)生的學(xué)習(xí)興趣一下子高漲起來，后面學(xué)習(xí)“小蝦的脾氣不好”這一部分，學(xué)生的理解也很透徹，一直有學(xué)生躍躍欲試，想表演。我想，在閱讀教學(xué)中，讓學(xué)生充分地讀，是理解感悟的前提。在課前預(yù)習(xí)時(shí)，我就要求學(xué)生反復(fù)讀課文，在第一課時(shí)教學(xué)時(shí)，更是讓學(xué)生充分地讀，正因?yàn)樽x得透徹，學(xué)生對于教學(xué)內(nèi)容已內(nèi)化于心，才能有

7、自己的創(chuàng)造想象。另外，教師也要善于調(diào)動(dòng)學(xué)生的學(xué)習(xí)興趣，善于在課堂上“煽風(fēng)點(diǎn)火，推波助瀾”，引導(dǎo)學(xué)生自己去思考，去探索，去學(xué)習(xí)！一年級下冊20以內(nèi)退位減法(20套)一年級下冊20以內(nèi)退位減法(20套)/一年級下冊20以內(nèi)退位減法(20套)20以內(nèi)退位減法13-9= 15-8= 14-7= 14-8= 11-3= 11-6= 13-7= 13-4= 16-9= 18-9= 13-9= 12-3= 12-4= 12-8= 15-6= 14-8= 11-8= 14-5= 11-9= 11-4= 13-6= 11-7= 11-8= 15-7= 12-5= 16-8= 12-8= 12-5= 11-6=

The beautiful isnt always good，is it？漂亮的不總是好的，是不是？9.陳述部分帶有seldom, hardly, never, rarely, few, little,nowhere, nothing等否定詞或半否定詞時(shí)，附加疑問部分的動(dòng)詞用肯定形式。

53、如：Bob rarely got drunk, did he?Few people know him, do they?She seldom goes to the cinema, does she?如果陳述部分的否定詞帶有否定前綴，那么，該陳述部分作肯定處理，附加疑問部分一般仍用否定形式。如：He was unsuccessful, wasnt he?Tom dislikes the book, doesnt he?10.當(dāng)陳述部分為主從復(fù)合句時(shí)，附加疑問部分一般應(yīng)與主句的主語和謂語動(dòng)詞保持對應(yīng)關(guān)系。如：She says that I did it, doesnt she?I told th

54、em not everybody could do it ,didnt I?注意：(1)當(dāng)陳述部分的主語是I，謂語是think, believe, suppose, expect這類動(dòng)詞時(shí)，附加疑問部分則往往與從句中的主語和謂語動(dòng)詞保持對應(yīng)關(guān)系，但要注意否定的轉(zhuǎn)移。I suppose that hes serious isnt he?I dont think she cares, does she?(2) 當(dāng)陳述部分是由Im sure that； Im afraid that； We are sure that； We are afraid that； I feel sure that； We

55、 feel sure that； It seems that等句型構(gòu)成時(shí)，因主要意思在從句，故疑問部分的主語要與從句的主語保持一致。例如： Im sure that you know him well，dont you？你肯定非常了解他，是吧？ It seems that you are an expert，arent you？你好像是個(gè)專家，對吧？(3) 當(dāng)陳述部分有It is said（told， reported， believed等）+that clause時(shí)，其反意疑問句的疑問部分要與從句中的主謂語保持一致。例如：It is reported that the police caug

56、ht the thief yesterday， didnt they？? It is said that she has won the first place in this competition， hasnt she？11.當(dāng)陳述部分是由連詞but，and，or，for等構(gòu)成的并列句時(shí)，附加疑問句則需和就近的分句的主語和謂語一致。如：Xiao Lin has been writing letters all afternoon but he should finish them now, shouldnt he?12.在由“祈使句+附加疑問”構(gòu)成的附加疑問句中，附加疑問部分一般用will

57、 you, wont you, would you,有時(shí)也可用can you, cant you, why dont you, could you等。A) 祈使句是否定形式，附加疑問句只能用肯定。 B) 祈使句是肯定形式，附加疑問句用肯定、否定均可。如：Dont open the door, will you?Give me some cigarettes, can you?Take a rest, why dont you?但是，以lets開頭的祈使句，附加疑問部分用shall we;以let us開頭的祈使句，如果含義是allow us，不包括聽話人在內(nèi)，疑問部分用will you。如：L

58、ets have a basketball match this afternoon, shall we?Let us go out for a rest, will you?13.當(dāng)陳述部分帶有情態(tài)動(dòng)詞must表示“必須”時(shí)，疑問部分用mustnt。如：You must work hard next term, mustnt you?I must answer the letter, mustnt I?但must(may, might) + have + V-ed表推測這層含義時(shí)，不能用must，而要根據(jù)陳述部分的結(jié)構(gòu)(即must之后的動(dòng)詞)以及含義采用相應(yīng)的動(dòng)詞形式。若含有表過去的時(shí)間狀語

59、則用過去時(shí)反問。如：You must have made a mistake, havent you?They must have seen the film last week, didnt they?He must be in the library, isnt he?14.當(dāng)陳述部分含有情態(tài)動(dòng)詞used to時(shí)，疑問部分可用usednt或didnt。如：The old man used to smoke, didnt he?或usednt he?Tom used to live here, usednt he?或didnt he?15. 當(dāng)陳述部分帶有情態(tài)動(dòng)詞ought to時(shí)，疑問部分
