同位語(yǔ)從句講義及練習(xí)
一、理解同位語(yǔ)從句的含義，把握同位語(yǔ)從句的實(shí)質(zhì)
在主從復(fù)合句中作同位語(yǔ)的從句稱(chēng)為同位語(yǔ)從句。同位語(yǔ)從句一般用that,whether，what, which, who,when, where, why, how 等詞引導(dǎo)，常放在fact,news,idea,truth,hope,problem,information,wish, promise, answer, evidence, report, explanation, suggestion, conclusion,等抽象名詞后面，說(shuō)明該名詞的具體內(nèi)容。換言之，同位語(yǔ)從句和所修飾的名詞在內(nèi)容上為同一關(guān)系，對(duì)其內(nèi)容作進(jìn)一步說(shuō)明。
例：the news that they had won the game soon spread over the whole school.他們比賽獲勝的消息很快傳遍了整個(gè)學(xué)校。
析：they had won the game說(shuō)明the news的全部?jī)?nèi)容，因此該句為同位語(yǔ)從句。
二、正確運(yùn)用同位語(yǔ)從句的引導(dǎo)詞，準(zhǔn)確把握同位語(yǔ)從句
1.如同位語(yǔ)從句意義完整，應(yīng)用that引導(dǎo)同位語(yǔ)從句。（即that 不充當(dāng)任何成分，只起連接作用）
例：the general gave the order that the soldiers should cross the river at once.將軍下達(dá)了戰(zhàn)士們立即過(guò)河的命令。
析：the soldiers should cross the river at once是the order的全部?jī)?nèi)容，且意義完整，因此應(yīng)用that引導(dǎo)同位語(yǔ)從句。
2.如同位語(yǔ)從句意義不完整，需增加"是否"的含義，應(yīng)用whether引導(dǎo)同位語(yǔ)從句。（if不能引導(dǎo)同位語(yǔ)從句）
例：we'll discuss the problem whether the sports meeting will be held on time.我們將討論運(yùn)動(dòng)會(huì)是否會(huì)如期舉行的問(wèn)題。
析：the sports meeting will be held on time意義不完整，應(yīng)加"是否"的含義才能表達(dá)the problem的全部?jī)?nèi)容，因此應(yīng)用whether引導(dǎo)同位語(yǔ)從句。
3.如同位語(yǔ)從句意義不完整，需增加"什么時(shí)候"、"什么地點(diǎn)"、"什么方式"等含義，應(yīng)用when,where,how等詞引導(dǎo)同位語(yǔ)從句。
例1：i have no idea when he will be back.
析：he will be back意義不完整，應(yīng)加"什么時(shí)候"的含義才能表達(dá)idea的全部?jī)?nèi)容，因此應(yīng)用when引導(dǎo)同位語(yǔ)從句。
例2：i have no impression how he went home,perhaps by bike.
析：he went home意義不完整，應(yīng)加"如何"的含義才能表達(dá)impression的全部?jī)?nèi)容，因此應(yīng)用how引導(dǎo)同位語(yǔ)從句。
4.當(dāng)主句的謂語(yǔ)較短，而同位語(yǔ)從句較長(zhǎng)時(shí)，同位語(yǔ)從句常后肢。
如：the thought came to him that maybe the enemy had fled the city. 他突然想到敵人可能已經(jīng)逃出城了。
