只有D是對的，意思是：當他馬上（就要）去開門時，他發現找不到鑰匙.填would open也表示表示“當他將要開門時…”，但是，be about to do，表示即刻或馬上就發生的動作，will（would）表示的動作遠比be about to do慢的…

When I entered the classroom，I found some students _____（watch）TV.為什麼答案寫的是were watching When I entered the classroom，I found some students _____（watch）TV. 為什麼答案寫的是were watching 新目標有一文章寫的是I found a boy crying in the corner. 這樣一看有衝突啊. 解釋一下.謝謝.

填watching和were watching都對！
填watching是分詞作賓補，單看I found some students watching TV.是個簡單句
填were watching，是found後面又帶一個賓語從句

怎麼改英語否定句和一般疑問句？Open the door，please.（否定句）We are classmates.（一般疑問句）

Don't open the door，please.
Are you classmates？
實義動詞句改否定句，在動詞前加don't，第三人稱單數加doesn't
有be動詞的句子改為一般疑問句，只要把be動詞提前，如果是第一人稱，改為第二人稱

將Open the door，please.（改成反意疑問句）

Open the door，please，will you？

could you please open the door否定句 could you please open the door？（否定句） _____you please _____open the door？

很高興能够在這裡回答你的問題，這道題的正確答案應該為：
Could you please not open the door？
