you can ring me between eight and nine.同义句能用call ...at

如果用call后面加时间段（between eight and nine）就不能加at,直接说：call me between right and nine.call...at 一般后面加的是特定的时间,比如call me at eight o'clock.
非要再找同义句的话,还能用：You can give me a call/phone call between eight and nine.
或：You can phone me between eight and nine.
