But she interrupted herself at that point. She had come in the form of a seed.She could not have known anything of any other worlds.Embarrassed over having let herself be caught on the verge of such a naive untruth, she coughed two or three times, in order to put the little prince in the wrong.

但她没有说下去。她来这儿的时候还是一颗种子呢，她哪里见过什么别的地方呢。她撒的谎幼稚可笑，让人一下子就能识破。她觉得有点羞怒，便咳嗽了两三声，想把过错推到小王子身上去

"The screen？”

“我要的屏风呢？”

“I was just going to look for it when you spoke to me..."

“你刚才跟我说的时候，我就准备去拿......”

Then she forced her cough a little more so that he should suffer from remorse just the same.

她又故意咳嗽，存心让他内疚不安。
