The hardy hybrid roses can shift for themselves.

Now life is as safe as I can make it until they are ready to shift for themselves.

现在，在他们准备好自己转移之前， 我的生活是尽可能安全的。

At last they are able to shift for themselves: and now will the old birds be able to take breath after their labours, and enjoy themselves a little?

最后，它们终于可以自己飞翔了。现在，老鸟们在劳累之后能喘口气，享受一下了吗？
