4、一篇寫小蝦生活習性的文章。通過觀察小蝦吃食、打架等細節的描寫，突出小蝦有趣、脾氣不好兩個特點，表達了我對小蝦的喜愛之情。課文比較淺顯易懂，以學習生字詞語，學習課文，了解小蝦的有趣之處，體會作者對小蝦的喜愛之情為目標，進而學習作者的觀察方法，為后面的作文教學打基礎。在第一課時的教學中，學生已掃清了字詞障礙，初讀了課文，了解了課文的主要內容，理清了文章脈落。在第二課時的學習中，我抓住小蝦的樣子、吃食有趣、脾氣不好三個重點段落來引導學習。在教學“吃食有趣”這段時，我設計了以下環節：1、小蝦怎樣吃東西？找出相關的句子。（小蝦真有趣。它們吃東西的時候非常小心，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，直到覺得沒有危險了，才用兩個鉗子捧著食物吃起來。）2、標畫出描寫小蝦吃東西的動詞。（碰 后退 再碰 又后退 捧著 吃）3、連接這些動詞的詞有哪些？（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到了什么？（動作敏捷 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？”這一環節的教學中，由于這是我給學生上的第一堂語文課，學生對我還不熟悉，初始有點膽怯，不敢參與，我即興表演了幾個動作，可能我的動作有點夸張，還沒表演完，就有一部分學

6、生笑起來了，還有幾個學生舉起了手，有一個學生的手舉得很高，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？像個小偷？”我一下子就笑開了，“那你能表演的更形象嗎？”這個學生自信地走上臺，惟妙惟肖地表演了小蝦吃食的樣子，甚至臉上都有了表情。“老師，我還能表演小蝦吃飽了的樣子！”學生的學習興趣一下子高漲起來，后面學習“小蝦的脾氣不好”這一部分，學生的理解也很透徹，一直有學生躍躍欲試，想表演。我想，在閱讀教學中，讓學生充分地讀，是理解感悟的前提。在課前預習時，我就要求學生反復讀課文，在第一課時教學時，更是讓學生充分地讀，正因為讀得透徹，學生對于教學內容已內化于心，才能有

7、自己的創造想象。另外，教師也要善于調動學生的學習興趣，善于在課堂上“煽風點火，推波助瀾”，引導學生自己去思考，去探索，去學習！一年級下冊20以內退位減法(20套)一年級下冊20以內退位減法(20套)/一年級下冊20以內退位減法(20套)20以內退位減法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=

49、，附加疑問句中的主語通常用they。但亦可用he，尤其是nobody, no one等作主語，具有否定概念時。如：Somebody phoned while I was out, didnt they?Everyone enjoyed the party, didnt they?Nobody wants to go there, does he?3.當陳述部分的主語是不定代詞everything, nothing, anything, something時，附加 疑問句中的主語一般用it，不用they。如：Everything seems all right now, doesnt it?No

50、thing is kept in good order, is it?Something must be done to stop pollution, isnt it?4.當陳述部分的主語是指示代詞this, that或these, those時，附加疑問句中的主語分別用it和they。如：This is important, isnt it?That isnt correct, is it?These are your friends Tom and Jack, arent they?5.如果陳述部分是以代詞one作主語，附加疑問句中的主語在正式場合用one，非正式場合用you,在美國英語

51、中，在非正式場合還可以用he。如：One cant be too careful, can one?或can you?One should do his duty, shouldnt he?6.如果陳述部分用Im結構，附加疑問部分一般用arent I。如：I am strong and healthy arent I。7.當陳述句為there be結構時，附加疑問句中的主語也用there。如：Theres no help for it, is there?Theres something wrong, isnt there?8. 若陳述部分的主語是“the +形容詞”表一類人時，疑問部分的主語

52、用they代替；若是表某一抽象概念時，疑問部分的主語用it代替。例如：The rich are not always very happy，are they？有錢人并不總是很開心，對不對？The young should respect the old，shouldnt they？年輕人應該尊重老年人，是吧？? 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，附加疑問部分的動詞用肯定形式。

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.當陳述部分為主從復合句時，附加疑問部分一般應與主句的主語和謂語動詞保持對應關系。如：She says that I did it, doesnt she?I told th

54、em not everybody could do it ,didnt I?注意：(1)當陳述部分的主語是I，謂語是think, believe, suppose, expect這類動詞時，附加疑問部分則往往與從句中的主語和謂語動詞保持對應關系，但要注意否定的轉移。I suppose that hes serious isnt he?I dont think she cares, does she?(2) 當陳述部分是由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等句型構成時，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？你好像是個專家，對吧？(3) 當陳述部分有It is said（told， reported， believed等）+that clause時，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.當陳述部分是由連詞but，and，or，for等構成的并列句時，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，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.當陳述部分帶有情態動詞must表示“必須”時，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，不能用must，而要根據陳述部分的結構(即must之后的動詞)以及含義采用相應的動詞形式。若含有表過去的時間狀語
