很不幸英语怎么说

a couple of time翻译成中文应该是：有好几次。这里的time应该要加s, a couple of times才对。

翻译：Unfortunately, on the way to school, my bike is broken, I had to run to school

The end of the story is very unfortunate

She isn't lucky.She had no luck.She has really poor luck.看你怎么说了

不幸应该是用：unfortunateshe is very unfortunate 例句：it appears like she is very unfortunate and life is treating her badly.

形容词，当然用lucky了

The end of the story very unfortunate

My home is near our school,so i often walk to my school,but sometimes i ride my bike to my school.
