快速答案
verificar 是核查的动作；constatar 是核查后确认的结论。
可靠的方法是先判断这个词在句子里的功能，再翻译。
每个词的作用
constatar
to establish or find
Use constatar for reaching a factual conclusion through observation or evidence.
verificar
to check or verify
Use verificar for examining whether information, a condition, or a process is correct.
如何选择
- constatar: Choose constatar if the sentence points to reaching a factual conclusion through observation or evidence.
- verificar: Choose verificar if the sentence points to examining whether information, a condition, or a process is correct.
例句
A perícia constatou o vazamento.
The inspection established that there was a leak.
Vou verificar os dados antes de publicar.
I will check the data before publishing.
常见误区
Do not announce that you constatou something before the evidence supports the conclusion. First verify, then possibly constatar.
