Question

—Some people now think there is no need to wear masks when going out.

—We can’t be ________ careful. ________.

A.so; Many hands make light work B.too; Actions speak louder than words

C.too; Prevention is better than cure D.very; Don’t put all your eggs in one basket

Answer

C

【解析】

句意：——有人认为现在外出时不需要戴口罩。——我们再小心也不为过。预防胜于治疗。

考查副词和情景交际。so 如此；too 太……；very 非常。Many hands make light work人多力量大；Actions speak louder than words 行动胜于雄辩；Prevention is better than cure预防胜于治疗；Don’t put all your eggs in one basket不要孤注一掷。can't be too 表示“再……也不为过/不过分”。根据语境，戴口罩是为了预防，预防胜于治疗。故选C。
