istohandletheproblem.S+V+PConclusion總結(jié)：思考：表語從句的結(jié)構(gòu)：表語從句的構(gòu)成:表語從句是指在復(fù)合句中做________的從句。它位于主句的_______之后，對主語進(jìn)行解釋說明，使主語的內(nèi)容具體化。表語系動詞+Thatiswhyit’scalledthepresent!引導(dǎo)詞簡單句Howtojudgewhetheritisapredicativeclause?系動詞狀態(tài)類：be感官類：feel/look/sound/taste/smell持續(xù)類：stand/remain/keep/stay變化類：become/get/grow/turn/go/come/run/fall好像類：seem/appear證明類：prove/turnout是...可以接表語從句系動詞有：......起來保持...變得...似乎、好像...結(jié)果是...;證明是...可以接表語從句系動詞有：記憶口訣：妝感正持續(xù)變好是.........起來保持...變得...似乎、好像...表從連詞引導(dǎo)詞___

1.Themostimportantthingisthatwefinishthefinaltask.2.Thequestioniswhetherwecanfinishitinsuchashorttime.3.Thereasonwhyhewaslateisthathegotuplate.用法歸納：a.that引導(dǎo)表語從句時，只起______作用，作/不作句子成分，有/沒有意義。（一般要求謂語動詞：think、believe、suppose等）b.whether引導(dǎo)表語從句時，只起______作用，作/不作句子成分，通常翻譯為“______”。注意，引導(dǎo)表語從句時通常不用if。連接√√是否主語是reason時，表語從句不能用because,

只能用that。主語是why引導(dǎo)的主語從句，表語從句不能用because,

只能用that。c.注意這個結(jié)構(gòu)：Thereasonwhy...is

that...連接√特殊用法：用法歸納：表示___________________(advice,suggestion,request,

proposal,demand,order)等名詞后面的表語從句要用虛擬語氣,即謂語動詞用“should

+動詞原形”,should可省略。Myadviceisthatyou(should)thinkitoverbeforeyoumakeadecision.Mysuggestionisthatweall___________(take)anactivepartinthecomingsportsmeeting.建議，要求，命令(should)take1)特定名詞+系動詞＋that+（should）do結(jié)構(gòu)1.Itsoundsasifsomeone___knockingatthedoor.

asif/asthough

引導(dǎo)從句的虛擬語氣：

若跟現(xiàn)在事實不符：過去式（be動詞用were）

若跟將來事實不符：would/could/might+動詞原形

若跟過去事實不符：haddone

二、從屬連詞：asif/thoughbecause引導(dǎo)的表語從句常見于"This/That/It

is/wasbecause..."句型中e.g.Hewassenttothehospital.That'sbecausehewasill.That'sbecause…強(qiáng)調(diào)
