"I have seven rulers" 可以用英文表示为 "I have seven rulers."

这句话的来源是指“我拥有七把尺子”这个意思。

例句:

"I need to measure this piece of wood, but I can't find my rulers. Oh wait, I have seven rulers in my drawer." (我需要测量这块木头，但我找不到我的尺子。哦，等等，我抽屉里有七把尺子。)
"I have seven rulers in my pencil case, but I only use one at a time." (我铅笔盒里有七把尺子，但我一次只用一把。)

注意：ruler 这个单词可以表示尺子或者统治者。在这里，是指尺子。
