"We are going to enter high school" 可以用英语表达为 "We are about to enter high school" 或 "We are entering high school soon"。
这两种表达都是通常用于将要做某事的说法，"about to" 和 "soon" 都是表示即将发生的意思。

"We are about to enter high school, and I'm a pttle nervous."
"We are entering high school soon, so we should probably start thinking about college."
这两句话都表示我们将要进入高中了。
