1、at first sight Yet again, what seems secure “at first sight ”appears not so secure when performing a full ***ysis. 然而，初见看起来安全的其实在执行完整的分析时并不那么安全。
2、first meet I can be but usually when I first meet somebody. 我有时候会，但是通常是和人靠前次认识的时候。
3、to see somebody for the first time 咱俩初次见面的光景我还记得很清楚。 I still remember very clearly the scene of our first meeting.
