根据下面五幅图画，以“Go Home on a Rainy Day”为题，写一篇100字左右的短文。内容必须符合题意，语意连贯，语言简练。 当汤姆在回家的路上时，天下起了大雨。他打开伞走得更快了。突然他看见一个老奶奶手里拿着拐杖蹒跚地往前走。她手里没有伞，全身都湿透了。汤姆走上前去试图和她共用一把伞。但老奶奶太高了，而他太矮，伞举得不够高。这时他看见老奶奶的拐杖，有了一个主意。他使劲地把拐杖系在了伞把上。伞够高了，老奶奶反复地感谢他。然后他们继续往家走了。 It was raining when Tom was on his way home. He opened his umbrella and walked faster. Suddenly he saw an old woman staggering forward with a stick in her hand. She hadn't got an umbrella with her and was wet all over. Tom went up to her and tried to share his umbrella with her. But the old woman was tall and he was too short to hold it high enough. Then he saw the old woman's stick and a good idea came to him. He tried hard to tie the stick to the handle of the umbrella. Then the umbrella was long enough for both of them. The old woman thanked him again and again. Then they went on walking home.
