三、用于人
表示人感觉热，又该用什么词呢?众多“热”词选手中，只有几个有此能力。
1、hot: if you feel hot, your body feels hot in a way that is uncomfortable : I was hot and tired after the journey.
The wine made her feel hot.
I feel so hot that I want to take off all my clothes.
不过，近几年在口语中，hot越来越多地指其他意思了。
A hot girl. She is hot. 等再也不是“感觉很热”的意思了。
2. bake(vi)used to say that a person or place is very hot :
We sat baking in the sun.
I’m baking!
I am baked in the scorching sun.
3. roasted/roasting: I am roasting/roasted in the scorching sun.
a roasting hot day
I’m absolutely roasting in this suit.
4. sweat/perspire:
sweat：I was sweating a lot despite the air conditioning.
sweat heavily/profusely (= sweat a lot ) Within minutes she was sweating profusely.
perspire：If you perspire, parts of your body become wet,especially because you are hot or have been doing hard work SYN sweat:
Willie was perspiring heavily.The game of squash left me perspiring profusely.He mopped his perspiring face with a handkerchief.
5、boiling: You must be boiling in that sweater.
(Informal) It is boiling hot in here.
四、用于物体(烧、灼烧相关)
1、 Singe: to damage hair, wool, paper etc by burning it slightly so that the ends or edges are burnt : The flames were hot enough to singe your eyebrows.singing，那成了“唱歌”啦，而是singeing
2、 scorch：To damage the surface of something by burning it so that a dark mark is left on it : Having the iron on a very high heat can scorch the fabric. The heater was left on all night and it scorched the wall.
直接灼烧物体表面导致表面烧焦留下一个烧焦(糊)的印迹――破坏性比singe强。例：Having the iron on a very high heat can scorch the fabric. The heater was left on all night and it scorched the wall.
3、 burn直接焚烧，以达到完全破坏之目的(等同于set fire to或set …on fire…这是明目张胆的“放火”了)――破坏性最强
4、 Scald: to burn your skin with very hot liquid or steam: The coffee was so hot it nearly scalded his tongue. It’s easy to knock a pan off the stove and scald yourself. | He was scalded by steam escaping from the broken pipe.
