We're going to be up there in just a few more weeks, and we expect that it's probably retreated another half a mile, but if I got there and discovered that it had collapsed and it was five miles further back, I wouldn't be the least bit surprised.
再过几个星期我们要去那里， 我们猜想它可能又后退了半英里， 但是如果我到那儿发现它已经坍塌了 而且往后又退了五英里，我一点也不会感到奇怪。
