Some stories are for swallowing. Imagine that you have found a good story, and, what is even more important, the time to enjoy it. You might be on holiday, or on a long train journey. If it is a good book, you might say, It's so good I can't put it dow

“这本书太好了，我舍不得把它放下。”但是并非所有的故事书都属于这一类。书评家们有时把一些书说成是“难以释手”的书，或者是“难以再读”的书。
