2015年職稱(chēng)英語(yǔ)考試語(yǔ)法之名詞性從句：
1.How some mammals came to live in the sea is not know.(主語(yǔ)從句)
2.The attorney told his client that they had little chance of winning the case.(賓語(yǔ)從句)
3.The problem is what we'll do next.(表語(yǔ)從句)
4.We have no idea that he has come back.(同位語(yǔ)從句)
同位語(yǔ)(Appositive)：
同位語(yǔ)是英語(yǔ)語(yǔ)法的重點(diǎn)內(nèi)容，也是各類(lèi)考試中的一個(gè)考點(diǎn)，同時(shí)，在寫(xiě)作中正確運(yùn)用同位語(yǔ)可以使你的句型更加簡(jiǎn)潔得體。
例：When reports came into London zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.
(當(dāng)倫敦動(dòng)物園接到報(bào)告說(shuō)，在倫敦以南45英里處發(fā)現(xiàn)一只美洲獅時(shí)，這些報(bào)告并沒(méi)有受到重視。)
在這里，a wild puma had been spotted forty-five miles south of London就是同位語(yǔ)從句，它本來(lái)應(yīng)該放在“reports”后面，這里卻被放在了謂語(yǔ)成分came into London zoo的后面，目的是讓句型顯得更為穩(wěn)重。
