### Chinese: 当我们身边有人倒下的时候，我们可以通过专业的知识去对他进行抢救，而不是傻傻地站在那里一动不动什么也做不了，这种无助的感觉太让人感到可怕了。
### English: When somebody falls down, we can conduct first aid with our professional knowledge, <v>but not doing nothing</v> by only standing there; this helpless feeling really makes people afraid.
### Errors: There is a minor style/awkward error at "but not doing nothing" within <v></v>.

### Improved English: When somebody falls down, we can conduct first aid with our professional knowledge, instead of doing nothing and only standing there; this helpless feeling is really frightening.
