Then, he began to walk along the sand reef toward the shore. He walked slowly stopping a few times to rest. He began to whistle.

然后，他开始沿着沙礁向岸边走去。他慢慢地走着，停下来休息了几次。他开始吹口哨。

So obviously, if you're reading a book and you're stopping 20 times in one page, your book is probably too difficult for you.

很明显，如果您正在阅读一本书并且在一页中停了 20 次， 那么您的书可能太难了。

但是，如果你因为新词汇而每页停四、五次，也许六次，作为一个新的英语学习者，那也不错。
