这里sense的用法很奇怪。
1. fire senses 这里指的是什么呢？
2. break 2 senses 也不会这么用, 如果我的某一个感官失灵，常用 lost my sense of …
例如：I completely lost my sense of taste and smell.

3.
sense：作名词讲， 它是个很灵活的单词，有很多含义。可译为“感官，意识，判断力, 意义”等等，但是要注意习惯搭配。
常见用法：
Dogs have a strong sense of smell. 狗的嗅觉很灵敏。
He felt a sense of loss.他感到失落。
a strong sense of duty 很强的责任感

建议有关sense，重新再造，或者背诵例句
