"heat" 的意思 不是讨厌，而是 热。例如：

1. The heat from the sun can be very intense.

2. I need to cool down after all that physical activity； I'm feeling the heat.

"heat" 作为动词时，意为 加热或 使变热，例如：

1. I need to heat up the dinner before I eat.

2. The furnace was turned up to high heat to melt the metal.

因此，"heat" 这个词与讨厌无关，而是与温度和热度有关。
