终于一线希望忽又来了.

At last a ray of hope appeared.

我们连一线希望也没有了。

There isn't a ray of hope left for us.

回想起很多一线心里叹息！

Look back on many a ray of hearts sigh!

但是，我还是希望看到这种现象的一线希望。

Nonetheless, I wish to see a ray of hope in this phenomenon.

这个提示使每个人心头闪现了一线希望，但是我却认为这纯粹是想入非非。

The suggestion sent a ray of hope in all their breasts, but I would have nothing to do with it.
