19. We three were running down the path,shouting and laughing when our dog Rubby suddenly stopped in the distance.He turned around,eyeing us,with his tail swinging up and down. My little brother Toby immediately sped up and rushed to where Rubby was.He bent down,picked up something and ran back to us. It was a bunch of keys.We gathered in a circle,examining the keys one by one,hoping to find some useful information about its owner.There were 3 keys,a house key,a mail key and a car key and a unique key fob(吊墜),very likely designed specially. "Gosh,the owner might be in great trouble," my sister sighed.She was right.We once lost our keys.Although we had an extra house key,it took our parents quite a long time to get a new mail key,let alone there was a car key. Who might have lost them? After many wild guesses,we finally drew a conclusion:It might belong to someone in our neighborhood as only our neighbors wandered into the woods for a walk.But it was still impossible to figure out who it was.We had a very big neighborhood. "The owner might come back to look for them," Toby reminded.So we decided to stay where we were,keeping a watchful eye on all passers-by.Our little dog ran in circles of excitement that we stayed so long in the wild.We remained in the woods for two hours,asking everyone we came across whether they lost their keys,but in vain. It seemed we had to give up.But my sister wouldn't,saying that she just couldn't stop picturing the owner brushing aside tall grasses hoping to find the lost keys. " How anxious and upset the owner would be!" I took a look at the bunch of keys again and quite by accident,found the key fob had the alarm button, "Look!If we press the alarm button,close enough of course,we can set off the owner's car alarm..." "That's brilliant." 注意:1.續(xù)寫詞數應為150左右; 2.請按如下格式在答題卡的相應位置作答。 We rushed back to our neighborhood.___________ The door opened and in front of us stood an old lady.___________
