done可以做主語嗎？

相當于名詞的成分才可作主語或賓語.being done作主語或賓語時是動名詞,相當于名詞,而done是過去分詞,相當于形容詞或副詞,不能充當名詞的作用,故不可作主語或賓語.

例：（１）Once spoken, a word becomes a promise.一言既出，駟馬難追．(作狀語）（２）Once poured, water can’t be taken back again.覆水難收．（作狀語）（３）Never corner a defeated enemy. 窮寇莫追 ． （４）Impressed by the beautiful scenery, I forgot togo back home in time. 流連忘返．（作狀語）（５）A fault once denied(否認) is twice committed(犯)（作表語）.否認錯誤等于錯上加錯．（６）A contented mind is a continual feast (宴席）．知足常樂．（作定語）（７）Grief(憂愁） divided is made lighter.分擔憂愁能使憂愁減輕．（作定語）You will feel very frustrated if you find yourselfsometimesmisunderstood by (被誤解）yourbest friends. (misunderstand)1.及物動詞的過去分詞稱為＿donebeing 加過去分詞稱為＿ being done.這兩者都與邏輯主語構成被動關系．2.在句中擔任主語和賓語時，只能用being dong,而不用 done．因為done具有形容詞和副詞的功能，不具有名詞的性質，所以 done不能作主語和賓語 .而 being done既可用作動名詞的例子：1.充當主語和賓語．(1)Being caught in a heavy traffic is quite an unpleasant experience.( 作主語)交通擁擠堵車是相當討厭的經歷．(2) He narrowly escaped being run over,．being done 和 done 都能作表語，但 being done的動作意義強，而 done只能表狀態．
