☆英语母语人士点评：

to limit: (as verb) to take away a part of something, but not entirely. Ex. "I'm going to limit your allowance if you keep forgetting to do your chores" (maybe only pay $5 instead of $10 or something I don't know) to restrict: (verb) much harsher, like a law against something. Ex. "There's a restriction against drinking alcohol here".

limit(作为动词)是指拿走某物的一部分，但不是全部。例:“如果你总是忘记做家务，我要限制你的零花钱”(也许只付5美元，而不是10美元或其他)。

限制（restrict）:严厉得多，就像针对某件事的法律。例:"这里禁止饮酒"。
