     “…She was married to an officer in India, long ago India; and she had a life of physical adventure(冒险) as exciting as her poetry. Her husband could cross rivers using crocodiles(鳄鱼) as stepping stones. He died when she was only 39. Unwilling to exist without him, she took her life, leaving a son in England."
     I stared at the paper,  reading, couldn't help thinking.
     Crocodiles are lazy animals as a rule, but they can move like lightening when they want to. And they don’t mind hurrying  they're hungry. There used to be lots in Indian rivers, living on fish mostly: but what's a little fish for a fifteen-foot crocodile? They ate people, fisherman or anyone else delicious enough to get too near; women doing the , or children playing at the water's . A hungry crocodile's mouth  over a meal with a sound like a gunshot. A big fellow can  in a man in two bites(咬). 

     That woman’s husband crossed rivers  from one crocodile's back to the next. I believe it. It had to be done quickly before the creature could see what was happening. It wasn't  a brave, active man; and no doubt he improved with practice. He could never look  while crossing. 

     The wife used to watch him—I felt sure of that. She lived  the adventure, the  excitement of it all. Their real life was with tigers, snakes. It's no wonder she wrote  poetry. 

     Then he died. I imagined how she felt. Was there another man  him in India, in the world? She was still young, hardly a sitting-room widow(寡妇).“I must  too”she said to herself. So she did what she felt she had to do. A  probably, to her head.
     But her young son, their son? Was her love for him nothing compared to her husband? Well, what do you think?
