Hayley教口語，“劃界”用英語怎么說？

/?di??l?m.?t/

to mark or describe the limits of something

標出…的界限，給…劃界

When you set the boundaries of something, you delimit it. Suburban homeowners often delimit their property lines with tall privacy fences.

當你為某件事設(shè)定邊界時，你就劃定了它的界限。郊區(qū)的房主經(jīng)常用高高的隱私圍欄劃定他們的房屋的界線。

Police powers are delimited by law.

警察的權(quán)限是由法律來劃定的。

There is also a figurative way to delimit, like when you delimit your summer schedule in an attempt to keep your cousin from visiting you for a month.

還有一種比喻的使用delimit的方式，比如你delimit你的暑期計劃，規(guī)劃出來一個時間段這樣讓你的表兄就不能在這期間來拜訪你。
