我第一次给学生做演讲时感到很紧张.I felt very nervous when I gave a speach for the students for the first time.I was very nervous the first time I gave a speach for the studentsI felt very nervous when...是否可用定从I felt nervous the first time when I gave a speech to many students.时间状从 for the first time可放在I felt very nervous 后面？换成含at the first的句子是怎样的呢？是否可用定从I felt nervous the first time when I gave a speech to many students.可以时间状从 for the first time可放在I felt very nervous 后面？可以换成含at the first的句子是怎样的呢？at the first?没有这个短语啊at the first time也没听过，也肯能是我才疏学浅也没听过，也肯能是我才疏学浅I felt nervous the first time I gave a speech to many students.这句貌似有问题对吧哪有问题？I felt nervous the first time和I gave a speech to many students间.缺什么吧the first time 直接引导时间状语从句，中间不必再加其他词。the first time 直接引导时间状语从句中间一定什么词都不加么？定从中when=at/for which且不可用that代替吧？It's the first time that中 that 可省吗 麻烦您了O(∩_∩)O~the first time 直接引导时间状语从句中间一定什么词都不加么？是，什么都不加。定从中when=at/for which且不可用that代替吧？是，相等，且不能用that代替。It's the first time that中 that 可以省略thanks~\(≧▽≦)/~
