Robber's Mask - Word Web

L.I - To find the most important (main) idea in a text.
Today for reading I had to read a text called Robber's Mask. When I was reading it I had to find the words I did not understand and make a word web on it. For the Word Web I had to find the synonyms, antonyms and the definition for the word. I found it hard to find antonyms for the words. In this Word Web I had learnt what reluctantly, sooty, tingle and sarcastically means.
