陳述句變一般疑問句
在句型轉(zhuǎn)換中陳述句變一般疑問句是常見的題型之一,這一節(jié)我們一起來討論如何將陳述句改為一般疑問句.在進入主話題之前請同學(xué)們回想一下我們學(xué)過了哪些時態(tài)?
Ss：一般現(xiàn)時,一般過去時,一般將來時,現(xiàn)在進行時,現(xiàn)在完成時……
T：對!這是我們必須掌握的五種時態(tài),實際上,我們還學(xué)過過去進行時,過去將來時和過去完成時,只是這三種時態(tài)在初中階段我們只須了解即可.我們今天要討論的陳述句變一般疑問句主要圍繞這些時態(tài)的句子進行.首先我們看一下一般現(xiàn)在時.誰來說一下該類句子謂語動詞的特點?
S1：含be動詞am ,is,are.
S2：含情態(tài)動詞can,may,must,need等.
S3：含實義動詞,如果句子主語是第三人稱單數(shù),謂語動詞要像名詞變復(fù)數(shù)一樣在詞尾加-s,-es.
T：Very good?那如果將含有這些動詞的句子變?yōu)橐话阋蓡柧溆衷撊绾?
S1：將be動詞提前.
S2：將情態(tài)動詞提前.
T：那如果是實義動詞呢?
S3：借助于助動詞do或does,如果句子的主語是第三人稱單數(shù)我們用does,此時原句里的第三人稱單數(shù)的動詞要還原.
T：對了,這一點是同學(xué)們最容易忽略的地方,下面兩個句子請同學(xué)們在變化時留點神.
We usually do our homework after school．
Helen often does her housework after office．
S4：句中的do,does是實義動詞而不是助動詞,在變化后句中還得保留do.
T：Quite right?同學(xué)們掌握得相當(dāng)不錯,下面我們要談?wù)摰幕旧弦源藶榛A(chǔ),只是對不同的時態(tài)有一點點小的變化而已.
S5：將來時將will（would）或shall（should）直接提前.
S6：進行時更簡單,be提前.
S7：完成時因have ／has或had是助動詞,同樣要把它前提.
T：一般過去時呢?
S8：借助于did呀,同樣要注意將原句中的動詞過去式還原.
T：看來同學(xué)們對陳述句變一般疑問句顯得相當(dāng)容易,這只是從方法形式上來講,但在實際改寫過程中大家往往因不注意一些小的問題而“痛失分數(shù)”.請大家在做此類轉(zhuǎn)換時始終要把“改”字放心間.
Ss：改?
T：對了,改大小寫,改標點符號,改……
Ss：改人稱,改詞語.
T：哪些詞在變化中要改?
S9：改any.
S10：含some的合成詞.
S11：already改為yet.
S12：老師,我們討論了這么多,你能像以前一樣給我們編個順口溜嗎?
T：好啊.請聽好：
陳述變疑問,兩種形式要分清.
Be、助、情,要提前,
行為實義三D幫,
一提二幫三改變,
變化多端好輕松.
