思路分析:

【1】本題考查的是改肯定句為否定句的基本方法。

【2】本題考查的是改陳述句為一般疑問(wèn)句的基本方法。

【3】本題考查的是常見(jiàn)句子的認(rèn)讀與書(shū)寫(xiě)。

【4】本題考查的是學(xué)生對(duì)句子意思的理解與關(guān)鍵詞的含義的把握。做此類題首先要明確劃線部分單詞或短語(yǔ)的意義,然后確定疑問(wèn)詞。

【5】本題考查的是復(fù)數(shù)句子與單數(shù)句子的互改。

名師解析:

【1】英語(yǔ)中改肯定句為否定句的基本方法是:1.主系表結(jié)構(gòu)的句子,有系詞am,is,are,was,were只要在系詞后面+not,例如:I am a teacher.----- I am not a teacher.

2.主謂賓的句子,有謂語(yǔ)動(dòng)詞,只要在主語(yǔ)后面+do的適當(dāng)形式+not 就行了。例如:

He runs fast.----- He doesn't run fast.主語(yǔ)是三單人稱,do也要用三單形式does,謂語(yǔ)動(dòng)詞是過(guò)去式,do也要變過(guò)去式did。

3.句中有助動(dòng)詞或情態(tài)動(dòng)詞的,只需要在助動(dòng)詞或情態(tài)動(dòng)詞后面直接+not ,就可以變否定句了,例如:She can dance well.----- She can't dance well

【2】要將陳述句變成一般疑問(wèn)句,可以遵循下列步驟:

1.看句中有沒(méi)有be動(dòng)詞(am、is、 are、 was、 were)、助動(dòng)詞(do、does、did、 have、 had)或情態(tài)動(dòng)詞(can、must、will、may等),如果有,將其提到句首,句末打上問(wèn)號(hào)即可。

例:Tom's father can play the piano.Can Tom's father play the piano?

2.如果句中沒(méi)有be動(dòng)詞、助動(dòng)詞或情態(tài)動(dòng)詞,則根據(jù)謂語(yǔ)動(dòng)詞的形式借助do的相應(yīng)形式放在句首。

具體方法是:

如果謂語(yǔ)動(dòng)詞是原形,則借do;

如果謂語(yǔ)動(dòng)詞是一般現(xiàn)在時(shí)第三人稱單數(shù)形式,則借does;

如果謂語(yǔ)動(dòng)詞是過(guò)去式,則借did。

需要注意的是,借does或did后,原句的謂語(yǔ)動(dòng)詞要變回原形。

例:They go to school by bike.Do they go to school by bike?

【3】根據(jù)逐個(gè)單詞意思的提示,應(yīng)該組成的句子意思是她在做什么?,時(shí)態(tài)現(xiàn)在進(jìn)行時(shí),結(jié)構(gòu)是be doing形式。因此答案為:What is she doing?

【4】根據(jù)所給句子的意思李雷12歲了,twelve表示年齡,對(duì)年齡進(jìn)行提問(wèn)應(yīng)使用how old。因此答案為:how old。

【5】將復(fù)數(shù)句變?yōu)閱螖?shù)句的時(shí)候,需要注意以下要點(diǎn):(1)指示代詞these或those分別變?yōu)閠his或that;(2)are要變?yōu)閕s或am;(3)可數(shù)名詞復(fù)數(shù)要為單數(shù)形式,并在前面加a或an;(4)如果主語(yǔ)是人稱代詞時(shí),它們也變?yōu)閱螖?shù)形式,即:we-I;you-you;they-she/he/it。因此答案為:is,child。
