she often appears on the stage as a young girl.she must appear in a bright red dress
这两句中一个appear 作为第三人称加了S.但是后面一句当中为什么没加S?

因为第二个appear前加了一个must,must又是一个情态动词,情态动词后边加动词要用动词原型,不管第几人称.即使是过去式,也是情态动词变过去式.记住就行了,情态动词后边加动词原型.

后一句中有情态动词 must ，所以必须用原形 appear 。

祝你开心。

您好！很高兴为您解答！
翻译：作为一个年轻女孩，她经常出现在舞台上，她的出现一定是穿着明亮的红色长裙。
因为第一个是第三人称单数she作为主语用三单形式，第二个因为有情态动词must，其后用动词原形，凡是有情态动词出现，不管是否第三人称单数做主语，其后的动词都用动词原形.。

希望可以帮到您，祝您成功！...
