请教用英语怎么说：我每个月都要洗一次红领巾,我每两个星期洗一次安全帽.

I wash my red scarf every month and wash my safety cap every two weeks.

Every month I wash a red scarf, I once every two weeks.

I wash my red-tie every month and wash my safety cap every two weeks.

I wash once every month red scarf, I wash once every two weeks helmets.
