stifling

Compared meaning: having a high temperature, very hot (adjective).

比较义项：温度高，很热（形容词）。

• hot

  The plain, all-purpose word for a high temperature; it works for food, weather, or objects and carries no hint of artificial heating or extreme intensity.

  这是表示“温度高”最普通、最通用的词，可以用来形容食物、天气或物体，既不暗示是被人为加热的，也不表示程度极端。

  The sand at the beach felt hot enough to burn my bare feet.

  沙滩上的沙子很热，几乎烫伤了我光着的脚。

• heated

  Describes something that has been warmed up, often by a device or deliberate process, such as heated seats or a heated pool, rather than being naturally hot.

  表示某物被加热或人为地变暖，通常是借助设备或特意的过程（如加热座椅、加温泳池），而不是自然而然地就很热。

  The car's heated seats felt wonderful on that freezing winter morning.

  在那个寒冷的冬日早晨，汽车的加热座椅感觉棒极了。

• blistering

  An intense, extreme degree of heat, usually describing sun, weather, or pace, strong enough to almost hurt the skin; stronger than plain hot.

  表示极端、强烈的高温，通常用来形容阳光或天气，热到几乎会伤害皮肤的程度，比普通的“hot”更强烈。

  Tourists sought shade to escape the blistering desert heat at noon.

  游客们在正午寻找阴凉处，以躲避沙漠中灼热难耐的高温。

• stifling 本词

  Combines heat with a lack of fresh air, describing an enclosed space so hot and airless that breathing feels difficult.

  把“热”和“空气不流通”结合在一起，形容一个封闭空间热得让人几乎喘不过气来，而不只是单纯温度高。

  The stifling office air made it hard to concentrate all afternoon.

  闷热得令人窒息的办公室空气让人整个下午都难以集中注意力。

Hot, heated, blistering, and stifling all mean very hot. Hot is the plain, general word for high temperature. Heated means warmed up, often artificially, like a heated seat. Blistering describes extreme, almost painful heat. Stifling means hot and airless, hard to breathe in.

这四个词都可以形容“很热”，但侧重点不同：hot最中性通用，heated强调是被加热或人为变暖的，blistering强调极端的高温程度，stifling强调闷热难以呼吸的空气环境。另外，heated还有“激烈的（如heated argument，激烈的争论）”的意思，blistering还可表示“极快的（如blistering pace，极快的速度）”，stifling也可比喻“压抑的（如stifling rules，令人窒息的规定）”，这些用法这里都不涉及。
