锁上

I remember padlocking the gate when I left for the post office.

我记得我离家去邮局时用挂把大上了的。

The door was locked on the outside.

那扇从外面上了。

My father locks every door in the house as he is paranoid about being robbed.

"我父亲患有妄想狂,常感到家里,所以总把每扇上。"

"I told you expressly to lock the door, but you didn't follow me."

"我明白地对你说过要上,但你没有听我的话。"

To their dismay, the door was locked.

使他们惊慌的, 已被上了。
