blind

Compared meaning: a covering that blocks something (noun).

比较义项：遮挡物（名词）。

• screen

  Screen is a mesh- or panel-like barrier that shields an area from insects, wind, view or intrusion; it does not necessarily block light and is common on doors, windows, patios or as a room divider.

  screen（遮挡物）指用来阻挡蚊虫、风、视线或外来侵扰的网状或板状屏障，不一定能遮光，常见于门、窗、露台，或用作房间隔断。

  We put a screen door on the porch to keep mosquitoes out in summer.

  我们在门廊装了一扇screen门，这样夏天就不会有蚊子飞进来了。

• blind 本词

  Blind specifically names slats or a fabric shade fitted to a window that can be raised, lowered or tilted to control how much light and privacy enter a room.

  blind（窗帘／百叶帘）特指安装在窗户上、由细板或布料制成、可升降或调节角度以控制进光量和隐私的遮光装置。

  She lowered the blind to keep the afternoon sun out of the living room.

  她放下了blind，这样午后的阳光就照不进客厅了。

Screen and blind both cover or block an area. Screen is a mesh or panel barrier against insects, wind, or view, but not always light. Blind is slats or fabric on a window, raised, lowered, or tilted to control light and privacy.

screen和blind在“遮挡物”这一意义上都指用来遮挡某个空间的物品，但screen强调阻隔视线、昆虫、风或外来侵扰的网状／板状屏障，不一定能遮光；blind专指装在窗户上、可升降或调节角度以控制光线和隐私的遮光装置。这里不比较screen作“屏幕”（如电脑屏幕）的意思，也不比较blind作形容词“失明的”的意思。
