　　定語從句中只能用which

　　定語從句中只能用which，不能用that的幾種情況：

　　1. 在介詞后面的關(guān)系代詞用which而不能用that。即“介詞+which(代物)” 例如：

　　The picture for which he paid $1,000 was once owned by a duke.

　　他花了1000美元買下的畫曾為一名公爵所擁有。

　　The building in which Han Mei studied was very old.

　　韓梅在里邊學(xué)習(xí)的那幢大樓很舊。

　　2. 在非限定性定語從句中不能用that。例如：

　　Crusoe's dog, which was very old now, became ill and died.

　　克魯索的狗，現(xiàn)在已經(jīng)很老了，病死了。

　　3. 有兩個(gè)定語從句，其中一個(gè)關(guān)系代詞已有which，另一個(gè)宜用that。相反，如果其中一個(gè)為that，另一個(gè)宜用which。

　　Edison built up a factory which produced things that had never been seen before.

　　愛迪生辦了一個(gè)工廠，生產(chǎn)過去從未見過的東西。

　　Let me show you the novel that I borrowed from the library which was newly open to us.

　　讓我給你看看我從新開放的圖書館借來的小說。

　　4與一般現(xiàn)在時(shí)連用的時(shí)間狀語

　　1) 表示頻度的副詞 always, often, usually, sometimes等。

　　2)表頻率的詞組，如: once a year, twice a month, three times a week等。

　　3)表一般現(xiàn)在的時(shí)間狀語如：on Sundays, on Monday afternoon, every day, every year 等。
