把这一句，留给此刻的你
It definitely helps to have been through the arm training flow before and to have used the arm on orbit, and it also gives me the confidence to know that our training facilities are really good, that when you get up there, you feel like you've been there.
以前进行过手臂训练，在轨道上使用过手臂，这无疑是有帮助的，这也给了我信心，让我知道我们的训练设施真的很好，当你到达那里时，你会觉得自己已经到了那里。
