各位親愛的可可網(wǎng)友們，歡迎走進(jìn)我們今天的《說法話茬》教室。我們今天來分析這個(gè)含有定語從句的復(fù)合句的錯(cuò)誤所在：

The reason of which he lost his wife was lack of medical care.

這句話的意思是：他們的死亡是缺乏醫(yī)療造成的。

在這個(gè)句子中主句是：the reason was lack of medical care，定語從句是：of which he lost his wife。這個(gè)定語從句修飾先行詞the reason。

The reason指代原因，在定語從句中做原因狀語。我想您很快會想到關(guān)系副詞why。我們可以用why來引導(dǎo)這個(gè)定語從句，即：The reason why he lost his wife。

但是寫作者是別出心裁，想用“介詞+which”來引導(dǎo)，但是有對這個(gè)介詞感到迷茫和疑惑。那么究竟這個(gè)介詞用什么呢？

我現(xiàn)在把the reason放入定語從句中，您來看這個(gè)空格處應(yīng)該用哪個(gè)介詞：He lost his wife the reason。這個(gè)空格處應(yīng)該用for。這樣引導(dǎo)詞就是for+which。

因此，我們今天對這個(gè)病句的疑問就水落石出了。此外，如果先行詞是reason的話，我們還可以用that來代替for which或者是why，而且that，for which或者是why都可以省略。

因此，我們今天的病句可以有四種說法：

1. The reason for which he lost his wife was lack of medical care.

2. The reason why he lost his wife was lack of medical care.

3. The reason that he lost his wife was lack of medical care.

4. The reason he lost his wife was lack of medical care.

記住了，定語從句修飾reason這個(gè)表示原因的先行詞的時(shí)候，可以用for which，why，that來引導(dǎo)，還可以省略這個(gè)三個(gè)引導(dǎo)詞。

您今天有收獲嗎？如果有收獲，就繼續(xù)鎖定我們的《說法話茬》節(jié)目，隨著我把定語從句扎扎實(shí)實(shí)地攻破下來。
