您提供的代码存在一些语法错误，可能是因为缺少一些分号或者括号不匹配。下面是修改后的代码：

public Jueseshuxing Shuxin;

public void Xuanze1_Button()
{
    Button1.SetActive(false);
    Button2.SetActive(false);
    Button3.SetActive(false);
    anniu = 1;
    Duihua(AA);
}

public void Xuanze2_Button()
{
    Button1.SetActive(false);
    Button2.SetActive(false);
    Button3.SetActive(false);
    anniu = 2;
    Duihua(AA);
}

public void Xuanze3_Button()
{
    Button1.SetActive(false);
    Button2.SetActive(false);
    Button3.SetActive(false);
    anniu = 3;
    Duihua(AA);
}

public void Continue_Button()
{
    Duihua(AA);
}

void duihua(int aa)
{
    if (aa == 0)
        switch (n)
        {
            case 0:
                Duihuakuang.text = "【序幕】";
                n++;
                break;
            case 1:
                Duihuakuang.text = "【漆黑的空间】\n【像是坠入了深渊般虚无与空洞......浓浓的窒息感】";
                n++;
                break;
            case 2:
                Duihuakuang.text = "【脑海中不断地响起....阵阵刺耳的声鸣。】";
                n++;
                break;
            case 3:
                Duihuakuang.text = "【α：滋....￥！@#%#！￥？滋%.....】";
                n++;
                break;
            case 4:
                Duihuakuang.text = "【α：...你...醒了吗？】";
                Button1_text.text = "【嗯.】";
                Button2_text.text = "【......】";
                Button3_text.text = "【你是谁？】";
                Button1.SetActive(true);
                Button2.SetActive(true);
                Button3.SetActive(true);
                Buttonjixu.SetActive(false);
                n++;
                break;
            default:
                if (anniu == 1)
                {
                    Duihuakuang.text = "【α：呵呵，我还以为你会选择沉默～】";
                    AA = 1;
                }
                if (anniu == 2)
                {
                    Duihuakuang.text = "【α：...这样呀～】";
                    AA = 2;
                }
                if (anniu == 3)
                {
                    Duihuakuang.text = "【α：我是...呵，你不必知道.】";
                    AA = 3;
                }
                n = 0;
                break;
        }
}

请注意，我只是修改了语法错误，但是代码的逻辑仍然需要您自己检查和修改。
