不幸的是怎么说英语

"Unfortunately" is a word that can be used to express that something is not desirable or fortunate. For example:
"Unfortunately, the weather is not very good today."
"Unfortunately, I won't be able to make it to the meeting."
You can also use the phrase "unluckily" to convey the same meaning. For example:
"Unluckily, I lost my keys and can't get into my house."
"Unluckily, we missed the train and now have to wait an hour for the next one."
Both "unfortunately" and "unluckily" can be used to indicate that something undesirable has happened or is likely to happen.
