系動(dòng)詞表語從句▲句子或主謂結(jié)構(gòu)做表語（而不是某個(gè)具體單詞做表語），這個(gè)句子就是表語從句。像這樣含有兩個(gè)及以上主謂結(jié)構(gòu)的句子，并且其中一個(gè)句子在另一個(gè)句子中充當(dāng)了成分，這樣的句子就叫做復(fù)合句。指出句子成分〖合作探究〗指出表語從句部分：Hehasbecomewhathewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthatweshouldstaycalm.4.Thequestioniswhenhecanarriveatthehotel.Hehasbecomewhat

hewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthat

weshouldstaycalm.4.Thequestioniswhen

hecanarriveatthehotel.一、表語從句定義：

表語從句是在復(fù)合句中作表語的名詞性從句,放在系動(dòng)詞之后,一般結(jié)構(gòu)是“主語+系動(dòng)詞+表語從句”。作用:對(duì)主語進(jìn)行解釋說明。例句：1）Theproblemisthatmillionsofpeopledieofillnessescausedbysmoking.2）ThequestionremainswhetherwecanwinClass3.
