英语月份用介词怎么说

In English, the months of the year are typically preceded by the preposition "in." For example:
"I was born in January."
"We're going on vacation in August."
"The meeting is scheduled for June."
Note that when referring to a specific date, you would use the preposition "on." For example:
"I'm going to meet her on the 15th of July."
It's also worth noting that when discussing the seasons, you would use the preposition "in." For example:
"I love going to the beach in the summer."
"I always get a cold in the winter."
