Question

如题：I asked if I could go and say hello and was told that the

Answer 1

1.第一个and连接并列谓语 asked 和was told

2.第二个and连接 that they could not see me or hear me 和 that I couldn't go back两个 was told的宾语从句.语法规定：连接并列宾语从句的that,从第二个宾语从句起的that 不能省略（第一个宾语从句的that可以省略).

3.at which I panicked 是典型的非限制性定语从句,at 来自于定语从句 谓语 panick at sth.的固定搭配.which指代前面两个宾语从句所说的内容.
