Recently，I took a trip home by train．I got a seat opposite a middle-aged man with sharp eyes，who kept______1  a young woman in a window seat with a little boy on her lap．The woman's eye fell on the man's face，and she immediately looked down and  2______  her scarf．

As the night wore on，people began to close their eyes，but the seats were so uncomfortable that only a very heavy sleeper could manage to get any  3______  ．The woman looked over at the man．He was still staring at her．She looked back at him with fire in her eyes．I was beginning to get  4______  ，too．

The train moved on．The little boy was   5______   awake on his mother's lap，but the woman dropped off to sleep．A moment later，he began to  6______  the half-open window—one leg went over it．The man jumped up and   7______  the child just before he fell out．

The  8______   woke up the woman．She seemed to be in  9______  ，and then reality dawned （显现）．“Your child has been looking for an opportunity to climb out of the window，”the man said as he gave the child back to her. ．“So I have been watching the whole time．”The woman was   10______  ，and so was I．
