連系動(dòng)詞+表語(yǔ)表語(yǔ)表語(yǔ)的功能是表述主語(yǔ)的特征、狀態(tài)、身份等。它也可以說(shuō)是一個(gè)主語(yǔ)補(bǔ)足語(yǔ)。它位于連系動(dòng)詞之后，與之構(gòu)成合成謂語(yǔ)；所謂的系表結(jié)構(gòu)，在系表結(jié)構(gòu)中，連系動(dòng)詞只是形式上的謂語(yǔ)動(dòng)詞起聯(lián)系作用，而真正起謂語(yǔ)作用的則是表語(yǔ)。(謂語(yǔ)部分)常見(jiàn)的系動(dòng)詞有：1.狀態(tài)系動(dòng)詞：be動(dòng)詞;2.感官系動(dòng)詞：look/feel/smell/taste/sound等；3.變化系動(dòng)詞：get/become/turn/grow/fall/grow等4.持續(xù)系動(dòng)詞：remain/stay/keep（仍然）5.表象系動(dòng)詞：seem/appear（似乎，好像）6.終止系動(dòng)詞：prove/turnout(結(jié)果是，證明是)Heisa

e.g.ThetroubleisthatIhavelosthisaddress.Thereasonforhisabsenceisthathehasn'tbeeninformed.2.that引導(dǎo)表語(yǔ)從句時(shí),僅起連接作用

e.g.Thequestioniswhetheryourunclewillofferhelptous.3.whether引導(dǎo)表語(yǔ)從句時(shí)，起連接作用，

①有“是否”之意②不充當(dāng)成分注意：if不能引導(dǎo)表語(yǔ)從句(1)從屬連詞:that&whether

用法歸納：a.that引導(dǎo)表語(yǔ)從句時(shí)，只起______作用，作/不作句子成分，有/沒(méi)有意義。b.whether引導(dǎo)表語(yǔ)從句時(shí)，只起______作用，作/不作句子成分，通常翻譯為“______”。注意，引導(dǎo)表語(yǔ)從句時(shí)通常不用if。連接√√連接√是否
