fact後面可用which引導從句嗎？——當然可以
fact的常見搭配如
despite the fact that…儘管…的事實
due to the fact that…由於…的事實
apart from the fact that…除開…事實外
given the fact that…考慮到…的事實
in view of the fact that…考慮到…的事實
the fact is/remains that…事實是/依然是……等，
the fact後接的通常是同位語從句，用來解釋說明the fact的具體含義，從而使得讀者或聽者對所陳述的信息更為明確。（當然the fact後的that也可以引導定語從句）
但也可看到fact（見到的是a fact which的組合）後接which的情況。
《COBUILD英漢雙解詞典》第672頁fact詞條3
If you say the fact that,a fact which, this fact, etc., you are referring to a situation or state of affairs that you have just mentioned or are about to mention, and suggesting that it is true.
使用the fact that或a fact which的句法結構或this fact等時，指剛剛提到過後即將提到的一個真實情況。
There wasn』t a great deal of warmth owing to the fact that Smithy had left the door open.
由於史密賽沒有關上門，屋子裡不很暖和。
They had waited in vain, a fact whichwas repeatedly explained to them.
他們白白等了許久，就這一事實再三向他們作了解釋。
——此句中的a fact which後接的是which所引導的定語從句，當然也可以使用that來引導。
《英語搭配大辭典》（王文昌主編）第643頁fact詞條
He unearthed several facts whichthrew light on…
他發現了一些能說明…的事實。
《新概念英語》第三冊第51課
