現在進行式可以用來表達幾種情況︰
1)一個動作、行為、狀態已經開始,仍然持續。
例) Sam is taking a picture for May. (森已經開了相機,正在對焦,還未按下拍攝鍵。)
例) I am reading. (我正在看書,可能看到中間第30頁,會持續翻頁。)
例) All the students are sitting in the hall. (學生們正坐在禮堂裏,大家都沒有動,維持坐着的狀態。)
2)計劃好將要發生的事情。
例) Joseph and Mary are having their wedding party next Wednesday.
"My table is obstructing the entrance of ABC School."一句寫桌子阻塞校門的狀態仍然持續,跟上面第3個例子屬同一種情況,可以用現在進行式。

假設事情的發生經過是︰
1) 我帶了桌子到校門前(桌子被我帶到校門前);然後
2) 桌子(被)留在那裏,阻塞了校門,
而我們希望一直把桌子當作主語來用,那麼我們會寫
My table was brought to the entrance of ABC School by me.
It has been left there, so now it is obstructing the school entrance.
其中''was brought"和"has been left"是用被動式,但到"obstruct"這個動詞配合主語"table"時,應該用主動式。

主動或被動,還是要看個別名詞跟動詞的正確配合。例如我們用中文說,桌子留在那裏,阻塞了校門,別人會明白我們的意思。但如果直接把「留在」譯成"stayed",用英文主動句寫"It stayed there, ...",便會很奇怪。所以我們會用被動句,把「留在」譯成"has been left"(被留在」。

"My table is obstructing the entrance of ABC School."一句也可以用the entrance of ABC School為主語,寫成被動句"The entrance of ABC School is being obstructed by my table."
