句子抄写有多处错误。

我查了一下原文出处：https://www.rchsd.org/health-articles/kids-talk-about-feeling-scared/

是这个样子：

Talking to a friend can help, especially if that person is supportive. About half the kids who took our survey said they’d been teased for being afraid. And even more — 75% — said they've sometimes said they weren’t afraid when they really were. So no teasing allowed. Encourage your friend today and maybe he or she will encourage you tomorrow!

国内一些英语考试用作“阅读理解”素材，被改的面貌全非了。

破折号可以表示同位关系或解释关系，所以 75% 和 even more 就是这种关系，指“人的数量”。

And even more — 75% — said they've sometimes said they weren’t afraid when they really were.

【翻译】甚至更多的人（占75%）说，他们有时说他们并不害怕，但实际上他们害怕。
