2、等等)二、當(dāng)句子中的主語(yǔ) S是單數(shù)第三人稱時(shí),動(dòng)詞單數(shù)第三人稱形式的變形規(guī)律 如下:1. 大局部的動(dòng)詞 +s ,如 run runs, swim swim, hop hop等2. 以ch, sh, o, x, s結(jié)尾的動(dòng)詞,必須+ es如:wash washesteach teach watch watds catch catchs do does go ges以X, S結(jié)尾的動(dòng)詞比擬少,只要記住此概念即可。3.以y結(jié)尾的動(dòng)詞,有兩種情況a.動(dòng)詞以y結(jié)尾,并且在y字母旁邊含有a,e,i,o,u其中一個(gè)字母,動(dòng)詞直接+s 女口: play plays 動(dòng)詞中y旁邊有a字母sway swaysb.

3、動(dòng)詞以y結(jié)尾,并且在y字母旁邊不含有a,e,i,o,u其中一個(gè)字母,動(dòng)詞必須 去掉y+ies女口: fly fies,cry cries,動(dòng)詞中不含有元音字母study stuies 動(dòng)詞中含有u,但是不在y的旁邊,必須去y+ies三、如何把陳述句改為一般疑問(wèn)句?可以按照以下步驟:1. 在陳述句中尋找isamarecanwill這幾個(gè)單詞 I am a good stude nt.He is a tall boy.They are cute flowers.I can run very fast.She will go to the park.2. 假設(shè)句子中出現(xiàn)以上幾個(gè)單詞,就直接把這幾個(gè)單

Can you run very fast?句子中出現(xiàn)I,都要改成youShe will go to the park. Will she

5、go to the park?3. 假設(shè)句子中沒(méi)有出現(xiàn)以上幾個(gè)單詞,就考慮用do does來(lái)進(jìn)行提問(wèn),放在句子的最前面。a. 當(dāng)句子的主語(yǔ)不是單數(shù)第三人稱時(shí),用do來(lái)提問(wèn),后面句子照抄,句子中的I變成youI like to eat apples. Do you like to eat apples?They have five cats?Do they have five cats?句子中主語(yǔ)I they都不是單數(shù)第三人稱,所以用do提問(wèn),放在句子最前面, 有I的地方改成you,其他不變。b. 當(dāng)句子的主語(yǔ)是單數(shù)第三人稱 時(shí),用does來(lái)提問(wèn),后面句子照抄,但是注意動(dòng) 詞必須改為原形。He

Does his daddy play balls with his frie nds?句子中主語(yǔ)He The bird His daddy都是單數(shù)第三人稱,所以用 does提問(wèn), 放在句子最前面,動(dòng)詞必須改為原形。一、寫出以下動(dòng)詞的第三人稱單數(shù)形式。討論第三人稱單數(shù)形式的變化規(guī)那么Model: clea nclea
