with对.with 后面接sth.而 to后面应接do sth.打错了，是You shouldn't take a risk to use/with that knife. to和with都对吗我想你应该还是打错了，是不是you should't take a risk to/with use that knife如果是这样，那就应用to，即you shouldn't take a risk to use that knife如果要用with的话得是you shouldn't take a risk with using that knifeyou should't take a risk to use that knifeyou should't take a risk with that knife都对吗抱歉，10悬赏这样就都正确了感谢
