如果你想表示在某个物体前面,你可以使用以下表达方式:

In front of: "I'm standing in front of the building."
Ahead of: "The store is ahead of us on the left."
Before: "There's a bench before the entrance."

例如:

"I'm standing in front of the building." (我站在建筑物前面。)
"The store is ahead of us on the left." (商店在我们左边前面。)
"There's a bench before the entrance." (门口前面有一个长椅。)

希望这对你有帮助!
